Purpose: The purpose of this study is to better understand the characteristics of the language-related skills of bilingual children with specific learning disorders. The aim is achieved by analyzing language-related skills in a sample of bilingual and Italian monolingual children, with and without SLD.Patients and methods: A total of 72 minors aged between 9 and 11 were recruited and divided into four groups: 18 Italian monolingual children with SLD, 18 bilingual children with SLD, 18 Italian monolingual children without (...) SLD, and 18 bilingual children without SLD. Each child underwent tests to evaluate different aspects of language skills: lexical and grammar, metalanguage and executive functions.Results: With regard to lexical and grammatical skills, the conditions of SLD and bilingualism both impact naming in terms of total number of errors for words with low frequency of use, while the condition of SLD has an effect on semantic errors for words with low frequency of use. The condition of bilingualism impacts on the total errors for words with high frequency of use and on circumlocution-type errors for words with low frequency of use. There were significant effects of bilingualism and SLD on the metalinguistic test for understanding implicit meaning, and an impact of SLD on phonological awareness was also found.Conclusion: The results suggest that both SLD and bilingualism have an effect on some lexical skills, in particular for words with low frequency of use. Both conditions, bilingualism and SLD, seem to impact on metalinguistic abilities that depend on lexical knowledge. These findings reinforce the importance of improving understanding of the neuropsychological profile of bilingual children with SLD. (shrink)

The present study examines the comorbidity between specific learning disorders and attention deficit and hyperactivity disorder by comparing the neuropsychological profiles of children with and without this comorbidity. Ninety-seven schoolchildren from 8 to 14 years old were tested: a clinical sample of 49 children with ADHD, SLD or SLD in comorbidity with ADHD, and 48 typically-developing children matched for age and intelligence. Participants were administered tasks and questionnaires to confirm their initial diagnosis, and a battery of executive function (...) tasks testing inhibition, shifting, and verbal and visuospatial updating. Using one-way ANOVAs, our results showed that all children in the clinical samples exhibited impairments on EF measures when compared with TD children. A more specific pattern only emerged for the updating tasks. Only children with SLD had significant impairment in verbal updating, whereas children with ADHD, and those with SLD in comorbidity with ADHD, had the worst performance in visuospatial updating. The clinical and educational implications of these findings are discussed. (shrink)

Lateral temporal measures of the auditory evoked potential including the T-complex, as well as an earlier negative peak index maturation of auditory/speech processing. Previous studies have shown that these measures distinguish neural processing in children with typical language development from those with disorders and monolingual from bilingual children. In this study, bilingual children with Turkish as L1 and German as L2 were compared with monolingual German-speaking children with developmental language disorder and monolingual German-speaking children with TD in order to (...) disentangle effects of limited language input vs. reduced perceptual abilities in the processing of speech and non-speech stimuli. Sensory processing reflected by the T-complex was compared in response to a German vowel and a sine-wave tone in the three groups of children, ages 5 through 6 years. Stimuli were presented while children watched a muted video. Auditory evoked potentials were time-locked to the vowels and tones. AEPs to the frequent stimuli within an oddball paradigm were analyzed at the left and right temporal electrode sites.The results revealed language status, stimulus, and language test measures all influenced the T-complex amplitudes. Particularly, the peak amplitude of Ta was modulated by language status and stimulus type. Bilingual children had significantly more negative Ta responses than the monolingual children with TD for both vowels and tones while DLD children differed from TD children only for the vowel stimulus. The amplitude of the T-complex was overall more negative at the left than at the right site. The Na peak latency was longer for the bilingual group than that observed for the two monolingual groups. The Tb latency was shorter for DLD and bilingual groups than that for TD children in the vowel condition, but no such latency difference between DLD and bilingual children was found. We suggest that the attenuated T-complex for bilingual children indicates continued plasticity of the auditory cortex to allow for learning of novel, second-language speech sounds. (shrink)

Background:The belief that we can control our thoughts is not inevitably adaptive, particularly when it fuels mental control activities that have ironic unintended consequences. The conviction that the mind can and should be controlled can prompt people to suppress unwanted thoughts, and so can set the stage for the intrusive return of those very thoughts. An important question is whether or not these beliefs about the control of thoughts can be reduced experimentally. One possibility is that behavioral experiments aimed at (...) revealing the ironic return of suppressed thoughts might create a lesson that could reduce unrealistic beliefs about the control of thoughts. Aims: The present research assessed the influence of the thought suppression demonstration on beliefs about the control of thoughts in a non-clinical sample, and among individuals with obsessive-compulsive disorder (OCD). Method: In Study 1, we assessed the effect of the thought suppression demonstration on beliefs about the control of thoughts among low and high obsessive individuals in the non-clinical population (N= 62). In Study 2, we conducted a similar study with individuals with OCD (N= 29). Results: Results suggest that high obsessive individuals in the non-clinical population are able to learn the futility of suppression through.. (shrink)

People with personality disorders should be treated fairly. Potential crime victims should be protected. That much is uncontroversial. The hard questions ask what is fair, when is protection adequate, and how should we achieve fairness and protection together. Peay outlines five main hurdles that the law must jump to reach these goals. All five raise serious challenges. To begin to address these challenges, we must first clarify what a personality disorder is. The notion of a personality disorder is defined (...) very broadly in DSM-IV-TR as any inflexible, pervasive, enduring, stable, and early-onset pattern of experience and behavior that deviates markedly from cultural expectations, leads to clinically ..

The distinction between students diagnosed with a learning disability and those considered merely slow learners is based on conceptually flawed assumptions that: 1) LD represents a brain dysfunction while SL does not; 2) LD is a well-defined disorder; 3) valid measurement instruments distinguish LD and SL; 4) special education for students with LD is fundamentally different from that for SL students. These erroneous beliefs are maintained because governmental legislation transformed a diagnosis of LD into an admission ticket to a (...) variety of government entitlements thereby subjecting it to political, legal, social and ideological forces.

Autism spectrum disorder is an inherited long-living and neurological disorder that starts in the early age of childhood with complicated causes. Autism spectrum disorder can lead to mental disorders such as anxiety, miscommunication, and limited repetitive interest. If the autism spectrum disorder is detected in the early childhood, it will be very beneficial for children to enhance their mental health level. In this study, different machine and deep learning algorithms were applied to classify the severity of autism spectrum (...) disorder. Moreover, different optimization techniques were employed to enhance the performance. The deep neural network performed better when compared with other approaches. (shrink)

Alcohol use disorder is a burden to society creating social and health problems. Detection of AUD and its effects on the brain are difficult to assess. This problem is enhanced by the comorbid use of other substances such as nicotine that has been present in previous studies. Recent machine learning algorithms have raised the attention of researchers as a useful tool in studying and detecting AUD. This work uses AUD and controls samples free of any other substance use to (...) assess the performance of a set of commonly used machine learning classifiers detecting AUD from resting state functional network connectivity derived from independent component analysis. The cohort used included 51 alcohol dependent subjects and 51 control subjects. Despite alcohol, none of the 102 subjects reported use of nicotine, cannabis or any other dependence or habit formation substance. Classification features consisted of whole brain rsFNC estimates undergoing a feature selection process using a random forest approach. Features were then fed to 10 different machine learning classifiers to be evaluated based on their classification performance. A neural network classifier showed the highest performance with an area under the curve of 0.79. Other good performers with similar AUC scores were logistic regression, nearest neighbor, and support vector machine classifiers. The worst results were obtained with Gaussian process and quadratic discriminant analysis. The feature selection outcome pointed to functional connections between visual, sensorimotor, executive control, reward, and salience networks as the most relevant for classification. We conclude that AUD can be identified using machine learning classifiers in the absence of nicotine comorbidity. (shrink)

Children with developmental language disorder (DLD) served as a test case for determining the role of extant vocabulary knowledge, endogenous attention, and phonological working memory abilities in cross-situational word learning. First-graders (Mage = 7 years; 3 months), 44 with typical development (TD) and 28 with DLD, completed a cross-situational word-learning task comprised six cycles, followed by retention tests and independent assessments of attention, memory, and vocabulary. Children with DLD scored lower than those with TD on all measures of (...) learning and retention, a performance gap that emerged in the first cycle of the cross-situational protocol and that we attribute to weaknesses in initial encoding. Over cycles, children with DLD learned words at a similar rate as their TD peers but they were less flexible in their strategy use, demonstrating a propose-but-verify approach but never a statistical aggregation approach. Also, they drew upon different mechanisms to support their learning. Attention played a greater role for the children with DLD, whereas extant vocabulary size played a greater role for the children with TD. Children navigate the problem space of cross-situational learning via varied routes. This conclusion is offered as motivation for theorists to capture all learners, not just the most typical ones.

Two lecture styles were examined to determine which was more effective for enhancing content learning in college students. The same experienced guest lecturer presented information about bipolar disorder (a combination of depression and mania) to college students in human service-related fields. Students in classes assigned to the control group received a standard, didactic lecture. In classes assigned to the experimental group, the presenter began the lecture by informing the students that she had bipolar disorder and enhanced the standard didactic (...) lecture by interspersing descriptions of her personal experiences living with bipolar disorder. Content-specific pre-tests and post-tests developed by the researchers were used to compare acquisition of knowledge about the disorder across groups of students. Results showed that students who received the personal/experiential lecture acquired significantly more knowledge about bipolar disorder than did students who received the standard, didactic lecture. Theories and procedures that may enhance student learning and thinking in related areas are discussed. (shrink)

This study investigates the procedural learning, retention, and reactivation of temporal sensorimotor sequences in children with and without developmental coordination disorder. Twenty typically-developing children and 12 children with DCD took part in this study. The children were required to tap on a keyboard, synchronizing with auditory or visual stimuli presented as an isochronous temporal sequence, and practice non-isochronous temporal sequences to memorize them. Immediate and delayed retention of the audio-motor and visuo-motor non-isochronous sequences were tested by removing auditory or (...) visual stimuli immediately after practice and after a delay of 2 h. A reactivation test involved reintroducing the auditory and visual stimuli after the delayed recall. Data were computed via circular analyses to obtain asynchrony, the stability of synchronization and errors. Firstly, an overall deficit in synchronization with both auditory and visual isochronous stimuli was observed in DCD children compared to TD children. During practice, further improvements were found for the audio-motor non-isochronous sequence compared to the visuo-motor non-isochronous sequence in both TD children and children with DCD. However, a drastic increase in errors occurred in children with DCD during immediate retention as soon as the auditory stimuli were removed. Reintroducing auditory stimuli decreased errors in the audio-motor sequence for children with DCD. Such changes were not seen for the visuo-motor non-isochronous sequence, which was equally learned, retained and reactivated in DCD and TD children. All these results suggest that TD children benefit from both auditory and visual stimuli to memorize the sequence, whereas children with DCD seem to present a deficit in integrating an audio-motor sequence in their memory. The immediate effect of reactivation suggests a specific dependency on auditory information in DCD. Contrary to the audio-motor sequence, the visuo-motor sequence was both learned and retained in children with DCD. This suggests that visual stimuli could be the best information for memorizing a temporal sequence in DCD. All these results are discussed in terms of a specific audio-motor coupling deficit in DCD.

A current issue in psycholinguistic research is whether the language difficulties exhibited by children with developmental language disorder [DLD, previously labeled specific language impairment ] are due to deficits in their abilities to pick up patterns in the sensory environment, an ability known as statistical learning, and the extent to which explicit learning mechanisms can be used to compensate for those deficits. Studies designed to test the compensatory role of explicit learning mechanisms in children with DLD are, (...) however, scarce, and the few conducted so far have led to inconsistent results. This work aimed to provide new insights into the role that explicit learning mechanisms might play on implicit learning deficits in children with DLD by resorting to a new approach. This approach involved not only the collection of event-related potentials, while preschool children with DLD [relative to typical language developmental controls] were exposed to a continuous auditory stream made of the repetition of three-syllable nonsense words but, importantly, the collection of ERPs when the same children performed analogous versions of the same auditory SL task first under incidental and afterward under intentional conditions. In each of these tasks, the level of predictability of the three-syllable nonsense words embedded in the speech streams was also manipulated to mimic natural languages closely. At the end of both tasks’ exposure phase, children performed a two-alternative forced-choice task from which behavioral evidence of SL was obtained. Results from the 2-AFC tasks failed to show reliable signs of SL in both groups of children. The ERPs data showed, however, significant modulations in the N100 and N400 components, taken as neural signatures of word segmentation in the brain, even though a detailed analysis of the neural responses revealed that only children from the TLD group seem to have taken advantage of the previous knowledge to enhance SL functioning. These results suggest that children with DLD showed deficits both in implicit and explicit learning mechanisms, casting doubts on the efficiency of the interventions relying on explicit instructions to help children with DLD to overcome their language difficulties.

Reading difficulties that are not addressed at the primary level continue to exist at the secondary level with serious consequences. Thus, it is important to provide struggling students with specific reading support. In particular, many students with learning disabilities and emotional behavioral disorders demonstrate reading obstacles and are at risk for motivation loss. A multiple baseline design was used to evaluate the effects of a motivational reading racetrack as peer-tutoring on the word reading skills of secondary students with (...) LD with and without EBD. The intervention was conducted through 4–5 baseline and 16–18 reading units three times a week for 15 min over 8 weeks. The results showed positive effects indicating a highly effective treatment. In addition, follow-up results were also promising. Our findings indicate that this multicomponent intervention has a positive effect on the word fluidity of low-achieving students in secondary education with LD and/or EBD. (shrink)

The present study investigates procedural learning of motor sequences in children with developmental coordination disorder and/or developmental dyslexia, typically-developing children and healthy adults with a special emphasis on the role of the nature of stimuli and the neuropsychological functions associated to final performance of the sequence. Seventy children and ten adults participated in this study and were separated in five experimental groups: TD, DCD, DD, and DCD + DD children and adults. Procedural learning was assessed with a serial (...) reaction time task that required to tap on a specific key as accurately and quickly as possible when stimuli appeared on the screen. Three types of stimuli were proposed as cues: the classical version of the SRTT with 4 squares aligned horizontally on the screen, giving visuospatial cues, and two modified versions, with 4 letters aligned horizontally on the screen and letters at the center of the screen. Reaction times during the repeated and random blocks allowed assessing three phases of learning: global learning, specific learning and retention of the sequence. Learning was considered as completed when RT evolved significantly in the three phases. Neuropsychological assessment involved, among other functions, memory and attentional functions. Our main result was that learning and retention were not influenced by the available cues in adults whereas learning improved with specific cues in children with or without neurodevelopmental disorders. More precisely, learning was not completed with L cues in children with neurodevelopmental disorders. For children with DD, learning was completed with the VS and VS + L cues whereas for children with DCD, learning was completed with combined VS + L cues. Comorbidity between DD and DCD had no more impact on procedural learning than DCD alone. These results suggest that learning depends on the nature of cues available during practice and that cues allowing learning and retention depend on the type of disorder. Moreover, selective attention was correlated with RT during retention, suggesting that this neuropsychological function is important for procedural learning whatever the available cues. (shrink)

More than three billion users are currently on one of Meta’s online platforms with Facebook being still their most prominent social media service. It is well known that Facebook has designed a highly immersive social media service with the aim to prolong online time of its users, as this results in more digital footprints to be studied and monetized. In this context, it is debated if social media platforms can elicit addictive behaviors. In the present work, we demonstrate in N (...) = 1,094 users that it is possible to predict from digital footprints of the Facebook users their self-reported addictive tendencies toward social media by applying machine-learning strategies. More specifically, we analyzed the predictive power of a set of models based on different sets of features extracted from digital traces, namely posting activity, language use, and page Likes. To maximize the predictive power of the models, we used an ensemble of linear and non-linear prediction algorithms. This work showed also sufficient accuracy rates in distinguishing between disordered and non-disordered social media users. In sum, individual differences in tendencies toward “social networks use disorder” can be inferred from digital traces left on the social media platform Facebook. Please note that the present work is limited by its cross-sectional design. (shrink)

Although emerging evidence has implicated structural/functional abnormalities of patients with Autism Spectrum Disorder, definitive neuroimaging markers remain obscured due to inconsistent or incompatible findings, especially for structural imaging. Furthermore, brain differences defined by statistical analysis are difficult to implement individual prediction. The present study has employed the machine learning techniques under the unified framework in neuroimaging to identify the neuroimaging markers of patients with ASD and distinguish them from typically developing controls. To enhance the interpretability of the machine (...) class='Hi'>learning model, the study has processed three levels of assessments including model-level assessment, feature-level assessment, and biology-level assessment. According to these three levels assessment, the study has identified neuroimaging markers of ASD including the opercular part of bilateral inferior frontal gyrus, the orbital part of right inferior frontal gyrus, right rolandic operculum, right olfactory cortex, right gyrus rectus, right insula, left inferior parietal gyrus, bilateral supramarginal gyrus, bilateral angular gyrus, bilateral superior temporal gyrus, bilateral middle temporal gyrus, and left inferior temporal gyrus. In addition, negative correlations between the communication skill score in the Autism Diagnostic Observation Schedule and regional gray matter volume in the gyrus rectus, left middle temporal gyrus, and inferior temporal gyrus have been detected. A significant negative correlation has been found between the communication skill score in ADOS_G and the orbital part of the left inferior frontal gyrus. A negative correlation between verbal skill score and right angular gyrus and a significant negative correlation between non-verbal communication skill and right angular gyrus have been found. These findings in the study have suggested the GM alteration of ASD and correlated with the clinical severity of ASD disease symptoms. The interpretable machine learning framework gives sight to the pathophysiological mechanism of ASD but can also be extended to other diseases. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:You Mean It’s Not My Fault:Learning about Lipedema, a Fat DisorderCatherine A. Seo“As a surgeon there is nothing more I can do for you. You need to lose 75 pounds before I can even consider repairing the damage done.” Implied and not directly stated, “… Because it’s your fault.” I sat listening, dumbfounded. I was at one of the top teaching hospitals in the country, face to face (...) with a respected Harvard Medical School trained surgeon who came highly recommended.I had seemingly irreversible damage that was leading to permanent immobility. I was experiencing excessive and uncontrollable swelling in my extremities. I was in unrelenting pain that prevented me from sleeping through the night.The surgeon looked down at the floor avoiding my gaze and—after never before mentioning weight as a possible contraindication to surgery during any of our interactions associated with five surgeries, in over two years, including at least 25 consultations, pre-op, post-op, or follow-up visits stated—in essence, “I can’t help you. You are too fat. It’s your fault.” Not until now, this moment, a couple of months after “the-surgery-gone-wrong-that-ended-in-terrible-complications,” I was being told that it was my fault.He then looked down at his pager that had conveniently buzzed within minutes after he delivered this news, and then walked out of the examining room leaving me to fend for myself in dealing with serious and life-changing complications. Susan1*, his Nurse Practitioner, printed out and handed me a standard listing of BMI calculations, marched me into the common hallway to weigh me, pointed out my BMI >30, reinforced the message that he would do nothing to remedy this horrific situation unless I lost 75 pounds, and then sent me on my way.I stood outside the hospital in shock. This just wasn’t happening, and it couldn’t be happening to me. I had grown to trust this surgeon, and I was struggling to comprehend what had just happened. As the shock wore off, I reengaged in several failed attempts to get help from him. He seemed to have convinced himself that the reason the surgery had gone awry was because of my excess weight, and not because, as I later learned, I had been misdiagnosed and the procedure, as it was performed, was far too aggressive. My health condition was deteriorating and it appeared as if weight was being scapegoated for the complications.If a solution was to be found, I was going to have to find it. After many months of research, I discovered that I have lipedema, an unrecognized [End Page E6] and generally misdiagnosed hereditary, genetically-based fat disorder. I had always had lipedema, which in my case seems to have been triggered at least since puberty. There are an estimated 17 million women in the USA alone who have lipedema, unrecognized or misdiagnosed.I, like most other women in America, knew that weight was a personal choice, and fat is a result of eating too much. Or was it? This ingrained and culturally accepted structure of knowledge began to disintegrate. I then asked the question, if this disease of lipedema is a fat disorder—and I had been to many, many doctors in my 63 years—why was it never identified? Why was I left to struggle in a constant battle trying to accomplish the impossible? I then learned about and named “anti-fat bias” and began to unravel the answers.About LipedemaAccording to Karen L. Herbst, Ph.D., M.D., endocrinologist and expert on fat disorders, lipedema (lipoedema in Europe) is an inherited genetic disease, affecting at least 11% of women of all sizes, from the extremely thin to the morbidly obese, resulting in localized fat that is bilateral, symmetrical and usually from the waist to just above the ankles. It can also affect the upper arms. Unlike the “normal” fat of obesity, lipedemic fat cannot be lost through diet and exercise. It is not uncommon for the comorbidity of overweight or obesity to accompany lipedema. Allen and Hines, physicians at the Mayo Clinic, first named Lipedema in 1940.Believed... (shrink)

Based on instructions people can form task representations that shield relevant from seemingly irrelevant information. It has been documented that instructions can tie people to a particular way of performing a task despite that in principle a more efficient way could be learned and used. Since task shielding can lead to persistence of inefficient variants of task performance, it is relevant to test whether individuals with attention deficit/hyperactivity disorder – characterized by less task shielding – are more likely and quicker (...) to escape a suboptimal instructed variant of performing a task. The paradigm used in this online study builds on the observation that in many environments different covarying features could be used to determine the appropriate response. For instance, as they approach a traffic light, drivers and pedestrians monitor the color and/or the position of the signal. Similarly, we instructed participants to respond to the color of a stimulus without mentioning that color covaried with the position of the stimulus. In order to assess whether with practice participants would use the non-instructed feature position to an increasing extent, we compared reaction times and error rates for standard trials to trials in which color was either ambiguous or did not match the usual covariation. Results showed that the covariation learning task can be administered online to adult participants with and without ADHD. Performance differences suggested that with practice ADHD participants might increase attention to non-instructed stimulus features. Yet, they used the non-instructed covarying stimulus feature to a similar extent as other participants. Together the results suggest that participants with ADHD do not lag behind in abandoning instructed task processing in favor of a learned alternative strategy. (shrink)

In this chapter, we investigate whether psychopathy is a mental disorder. We argue that addressing this question requires engaging, at least, with three principal issues that have conceptual, empirical, and normative dimensions. First, it must be established whether current measures of psychopathy individuate a unitary class of individuals. By this we mean that persons classifed as psychopaths should share some relevant similarities that support explanation, prediction, and treatment. Second, it must be proven that psychopathy harms the person who has it. (...) Third, it must be established that the harm associated with psychopathy is relevant for the ascription of disorder status. Regarding this latter issue, we argue that psychopathy should be considered a disorder if its harmfulness derives from certain incapacities or limited capacities. These incapacities should affect basic competences that are justifably required for conducting a preferable type of life. Within this framework, we tentatively advance the hypothesis that some normatively justifed conclusions and empirical evidence about psychopathy, that needs nonetheless to be further investigated, might support the claim that people with psychopathy have a mental disorder.

I examine the phenomenon of implicit learning, the process by which knowledge about the rule-governed complexities of the stimulus environment is acquired independently of conscious attempts to do so. Our research with the two seemingly disparate experimental paradigms of synthetic grammar learning and probability learning, is reviewed and integrated with other approaches to the general problem of unconscious cognition. The conclusions reached are as follows: Implicit learning produces a tacit knowledge base that is abstract and representative (...) of the structure of the environment; such knowledge is optimally acquired independently of conscious efforts to learn; and it can be used implicitly to solve problems and make accurate decisions about novel stimulus circumstances. Various epistemological issues and related problems such as intuition, neuroclinical disorders of learning and memory, and the relationship of evolutionary processes to cognitive science are also discussed.

Defining Mental Disorder: Jerome Wakefield and His Critics, edited by Denis Forest and Luc Faucher, is essential reading for students and researchers in philosophy of medicine whose work is informed by that of Jerome Wakefield, or the disease debate in general. If you are anything like me, this book will open the door to a new depth of understanding of the harmful dysfunction analysis (HDA) and its methodical underpinnings, and an enriched appreciation of what is at stake in defining medical (...) disorder. To those confident that they understand Wakefield’s view and the surrounding debate, thinking perhaps that they do not need a refresher, I would say: perhaps you do not understand it as well as you think. Defining Mental Disorder provides much more than an overview of previously well-trodden ground. The chapters themselves, and Wakefield’s own detailed responses, help to elucidate a number of methodological nuances and peculiarities that have rarely been covered in such depth before. I was startled to learn how philosophically complex Wakefield’s position actually is, and how shallow my own understanding of it has been. It emerges as a far more nuanced and sophisticated account than I had given it credit for, and one that deserves serious reevaluation. (shrink)

In this dissertation, I examine our mental health concepts to see what work they are currently doing as well as what work they could be doing. In 1976, Christopher Boorse stated that the mental health literature is a “web of obscurities” (p. 51). To resolve some of this confusion, I argue that we need to consider the goals we should have for our mental health concepts and then give accounts of those concepts that meet our stated goals. I argue that (...) our goals for our mental health concepts should be twofold: first, we need concepts that will work to alleviate the stigmatization of mental disorder as this stigmatization gets in the way of providing and receiving medical help, and second, we need concepts that will be useful tools for medical practitioners to use in their diagnosis and treatment practices. -/- I begin by arguing that our mental disorder concept is not currently a useful tool for medical practitioners. Moreover, I argue that our mental disorder concept is confused in such a way that it is unlikely that it could ever be a useful tool for medical practitioners. If we cannot give an account of the mental disorder concept that is a useful tool for medical practitioners, then perhaps we can give an account of the mental disorder concept that can be used toward our goal of alleviating the stigmatization of mental disorder. Before we can do that, however, we need an account of the stigmatization concept so that we can understand what our mental disorder concept needs to be alleviating. -/- I argue that stigmatization is a process whereby some entity becomes marked as disgraceful or shameful. This stigmatization process includes (1) an attitude against the entity for reasons found in the social ideology, and (2) acts against the entity. I then argue that acts of stigmatization take two forms: direct stigmatization (where stigmatizors take acts against the stigmatized entity) and indirect stigmatization (where potential victims of stigmatization take acts to avoid becoming victims of stigmatization). With that in mind, we learn that if we are to alleviate the stigmatization of mental disorder, we need to work on alleviating both direct and indirect stigmatization. It is at this point that I argue for a new account of our mental disorder concept that can be utilized to alleviate the direct and indirect stigmatization of mental disorder. With our mental disorder concept redesigned to achieve that goal, I turn to the goal of providing medical help for persons that need that help. I argue that we need to reconceptualize what it means to be a ‘diagnosable condition’ so that we can develop a new framework for diagnosis and treatment that will be more efficacious than our current system. In conclusion, I suggest that we can untangle the current confusion that is the mental health literature by imbuing our mental health concepts with specific purposes and then utilizing them to achieve those purposes as I outline in this dissertation.

We have made huge progress in understanding the biology of mental illnesses, but comparatively little in interpreting them at the psychological level. The eminent philosopher Jonathan Glover believes that there is real hope of progress in the human interpretation of disordered minds. -/- The challenge is that the inner worlds of people with psychiatric disorders can seem strange, like alien landscapes, and this strangeness can deter attempts at understanding. Do people with disorders share enough psychology with other people (...) to make interpretation possible? To explore this question, Glover tackles the hard cases—the inner worlds of hospitalized violent criminals, of people with delusions, and of those diagnosed with autism or schizophrenia. Their first-person accounts offer glimpses of inner worlds behind apparently bizarre psychiatric conditions and allow us to begin to learn the “language” used to express psychiatric disturbance. Art by psychiatric patients, or by such complex figures as van Gogh and William Blake, give insight when interpreted from Glover’s unique perspective. He also draws on dark chapters in psychiatry’s past to show the importance of not medicalizing behavior that merely transgresses social norms. And finally, Glover suggests values, especially those linked with agency and identity, to guide how the boundaries of psychiatry should be drawn. -/- Seamlessly blending philosophy, science, literature, and art, Alien Landscapes? is both a sustained defense of humanistic psychological interpretation and a compelling example of the rich and generous approach to mental life for which it argues.

It is often assumed that similar domain-specific behavioural impairments found in cases of adult brain damage and developmental disorders correspond to similar underlying causes, and can serve as convergent evidence for the modular structure of the normal adult cognitive system. We argue that this correspondence is contingent on an unsupported assumption that atypical development can produce selective deficits while the rest of the system develops normally (Residual Normality), and that this assumption tends to bias data collection in the field. (...) Based on a review of connectionist models of acquired and developmental disorders in the domains of reading and past tense, as well as on new simulations, we explore the computational viability of Residual Normality and the potential role of development in producing behavioural deficits. Simulations demonstrate that damage to a developmental model can produce very different effects depending on whether it occurs prior to or following the training process. Because developmental disorders typically involve damage prior to learning, we conclude that the developmental process is a key component of the explanation of endstate impairments in such disorders. Further simulations demonstrate that in simple connectionist learning systems, the assumption of Residual Normality is undermined by processes of compensation or alteration elsewhere in the system. We outline the precise computational conditions required for Residual Normality to hold in development, and suggest that in many cases it is an unlikely hypothesis. We conclude that in developmental disorders, inferences from behavioural deficits to underlying structure crucially depend on developmental conditions, and that the process of ontogenetic development cannot be ignored in constructing models of developmental disorders. Key Words: Acquired and developmental disorders; connectionist models; modularity; past tense; reading. (shrink)

This article gives an overview of what we can learn about face perception from studying its disorders. The term “disorders” is broadly interpreted to include acquired brain injury and disease, neurodevelopmental differences, and neuropsychiatric problems. The article examines the reasons for various opinions about what can be learnt from disorders, ranging from the entire spectrum from “nothing that isn't misleading” to “everything worth knowing.” Cognitive neuropsychology typically operates in a unique way, in which the emphasis is on (...) detailed analysis of individual patients with theoretically interesting impairments. The article then highlights a number of the assumptions that get made, explains why things are often complicated, and emphasizes the value of a pragmatic “converging operations” approach in which evidence from disorders of face perception is brought together with other sources of data and theory.

Background Genomic research on neurodevelopmental disorders (NDDs), particularly involving minors, combines and amplifies existing research ethics issues for biomedical research. We performed a review of the literature on the ethical issues associated with genomic research involving children affected by NDDs as an aid to researchers to better anticipate and address ethical concerns. Results Qualitative thematic analysis of the included articles revealed themes in three main areas: research design and ethics review, inclusion of research participants, and communication of research results. (...) Ethical issues known to be associated with genomic research in general, such as privacy risks and informed consent/assent, seem especially pressing for NDD participants because of their potentially decreased cognitive abilities, increased vulnerability, and stigma associated with mental health problems. Additionally, there are informational risks: learning genetic information about NDD may have psychological and social impact, not only for the research participant but also for family members. However, there are potential benefits associated with research participation, too: by enrolling in research, the participants may access genetic testing and thus increase their chances of receiving a (genetic) diagnosis for their neurodevelopmental symptoms, prognostic or predictive information about disease progression or the risk of concurrent future disorders. Based on the results of our review, we developed an ethics checklist for genomic research involving children affected by NDDs. Conclusions In setting up and designing genomic research efforts in NDD, researchers should partner with communities of persons with NDDs. Particular attention should be paid to preventing disproportional burdens of research participation of children with NDDs and their siblings, parents and other family members. Researchers should carefully tailor the information and informed consent procedures to avoid therapeutic and diagnostic misconception in NDD research. To better anticipate and address ethical issues in specific NDD studies, we suggest researchers to use the ethics checklist for genomic research involving children affected by NDDs presented in this paper.

This paper discusses the current fashion for brain-based learning, in which value-laden claims about learning are grounded in neurophysiology. It argues that brain science cannot have the ‘authority’ about learning that some seek to give it. It goes on to discuss whether the claim that brain science is relevant to learning involves a category mistake. The heart of the paper tries to show how the contribution of brain science to our grasp of the nature of (...) class='Hi'>learning is limited in principle. Finally the paper explores the potential of brain science to illuminate specific learning disabilities. (shrink)

Currently, there is an increasing number of older population groups, especially in developed countries. This demographic trend, however, may cause serious problems, such as an increase in aging diseases, one of which is dementia whose main symptom consists in the decline of cognitive functioning. Although there has been ongoing pharmacological research on this neurological disorder, it has not brought satisfying results as far as its treatment is concerned. Therefore, governments all over the world are trying to develop alternative, non-pharmacological strategies/activities, (...) which could help to prevent this cognitive decline while this aging population is still healthy in order to reduce future economic and social burden. One of the non-pharmacological approaches, which may enhance cognitive abilities and protect against the decline in healthy older population, seems to be the learning of a foreign language. The purpose of this mini-review is to discuss recent findings about the effect of foreign language learning on the enhancement of cognitive functions among healthy older individuals. The findings, divided into three research areas, show that the learning of a foreign language may generate a lot of benefits for older individuals, such as enhancement of cognitive functioning, their self-esteem, increased opportunities of socializing, or reduction of costs. However, as Ware et al. (2017) indicate, any intervention program on foreign language learning should be well thought of and tailored to the needs of older people in order to be effective and avoid accompanying factors, such as older people’s anxiety or low self-confidence. Nevertheless, more empirical studies should be done in this area. (shrink)

Vocal imitation in songbirds exhibits interesting parallels to infant speech development and is currently the model system of choice for exploring the behavioural, molecular and electrophysiological substrates of vocal learning. Among songbirds, the Zebra Finch ( Taeniopygia guttata ) is currently used as the `flying mouse' of birdsong research. Only males sing and they develop their song primarily during a short sensitive period in early life. They learn their speciesspecific song patterns by memorizing and imitating the songs of conspecifics, (...) mainly adults. Since Immelmann's pioneering work, thousands of zebra finches have been raised in strictly controlled auditory environments to examine how their experience affected their songs. In this article, I review the different experimental procedures that have been used in the laboratory to study the social influences on song learning in the Zebra Finch. Poor song learning was observed using passive playback of taped songs, whereas self-eliciting exposure using operant tutoring techniques induced significant learning, but with a high interindividual variability. The success of the training paradigm is often measured by the quality of imitation of the songs to which the young bird is exposed. Using empirical evidence from the field and the laboratory, I will also discuss this issue, by summarizing possible advantages and disadvantages of producing a perfect imitation. So far, the best method to get a close copy of a song model in the Zebra Finch is to place a single young bird with an adult male. This situation, which is rather unnatural, does not meet the criteria for precise control necessary in experimental conditions. Optimizing the methods used to train a zebra finch to learn a song, in order to be able to predict the imitation success, will improve our understanding of the dynamics of vocal production learning. It would also consolidate this species as a research model of relevance to human speech development and disorders. Keywords: Zebra Finch; birdsong; learning; development; memory; social influences.

Managing the violent behaviour of mentally disordered offenders is challenging in all jurisdictions. We describe the ethical framework and practical management of MDOs in England and Wales in the context of the move to equivalence of healthcare between hospital and prison. We consider the similarities and differences between prison and hospital management of the violent and challenging behaviours of MDOs. We argue that both types of institution can learn from each other and that equivalence of care should extend to equivalence (...) of criminal proceedings in court and prisons for MDOs. We argue that any adjudication process in prison for MDOs is enhanced by the relevant involvement of mental health professionals and the articulation of the ethical principles underpinning health and criminal justice practices.

This literature review focused on effective teaching strategies for children with Attention Deficit Hyperactivity Disorder (ADHD) in classrooms where English as a Foreign Language (EFL) is taught, which is undoubtedly a novel and crucial issue that demands immediate attention. This review not only concentrates on identifying the teaching strategies used for students with ADHD but also delves into and considers different teaching approaches and inclusive education adaptations for students with ADHD. The impact of this review might be significant for educators, (...) parents, and stakeholders alike since it could provide valuable recommendations and knowledge based on the evidence gathered. This would lead to developing more effective, efficient, and inclusive teaching strategies or mechanisms for students with ADHD. Programs aimed at teacher training could also benefit from the findings of this review, contributing to the general support and improving the academic experience of students with ADHD in foreign language learning environments.

Deep brain stimulation (DBS) is an effective treatment for the debilitating motor symptoms of Parkinson’s disease and other neurological disorders. However, clinicians and commentators have noted that DBS recipients have not necessarily experienced the improvements in quality of life that would be expected, due in large part to what have been described as the ‘psychosocial’ impacts of DBS. The premise of this paper is that, in order to realise the full potential of DBS and similar interventions, clinical services need (...) to be arranged in such a way that these psychosocial dimensions are recognised and managed. Our starting point is that the psychosocial effects of DBS ‘in the field’ present us with analytically-useful disruptions: they disturb and foreground deeply held assumptions relating to the individual, health and its treatment, and which in a crude form manifest as the myth of technological solutionism within health care. Drawing on scholarship in medical sociology and science and technology studies (STS), we argue that DBS brings to the fore the relational dimensions of personhood, and demonstrates the emotional and social turmoil that can result if the relational dimensions of personhood are ignored by clinical services. In light of this, we argue that DBS should be implemented within a regime of care. Drawing on ethnographic research of a paediatric DBS clinical service, we provide an example of a regime of care, and conclude by reflecting on what other DBS services might learn from this paediatric service.

The Affective grounding hypothesis suggests that affective experiences play a crucial role in abstract concepts’ processing (Kousta et al. 2011). Vigliocco and colleagues test the role of affective experiences as well as the role of language in learning words denoting abstract concepts, comparing children with typical and atypical development. They conclude that besides the affective experiences also language plays a critical role in the processing of words referring to abstract concepts.
