The paper reviews the current situation regarding a new theory of brain dynamics put forward by the authors in an earlier publication. Motivation for the theory is discussed in terms of two issues: the long-standing problem of accounting for the stability and nonlocal properties of memory, and the experimental and theoretical evidence against the classical theory of brain action. It is shown that the new theory provides an explanation and a conceptually unifying framework for phenomena of brain action that (...) resist classical explanation. Further independent experiments provide strong additional support for the theory. The fact that this theory incorporates quantum mechanisms in an essential way is considered to be of wide scientific interest in view of the unique status of the brain in relation to the physical, biological, and mental orders in nature.

The puzzle of the absentminded driver combines an unstable decision problem with a version of the Sleeping Beauty problem. Its analysis depends on the choice between “halfing” and “thirding” as well as that between “evidential” and “causal” decision theory. I show that all four combinations lead to interestingly different solutions, and draw some general lessons about the formulation of causal decision theory, the interpretation of mixed strategies and the connection between rational credence and objective chance.

It is critical to remember details about meetings with healthcare providers. Forgetting could result in inadequate knowledge about ones' health, non-adherence with treatments, and poorer health outcomes. Hearing the health care provider plays a crucial role in consolidating information for recall. The recent COVID-19 pandemic has meant a rapid transition to videoconference-based medicine, here described as telehealth. When using telehealth speech must be filtered and compressed, and research has shown that degraded speech is more challenging to remember. Here we present (...) preliminary results from a study that compared memory for health information provided in-person to telehealth. The data collection for this study was stopped due to the pandemic, but the preliminary results are interesting because the pandemic forced a rapid transition to telehealth. To examine a potential memory deficit for health information provided through telehealth, we presented older and younger adults with instructions on how to use two medical devices. One set of instructions was presented in-person, and the other through telehealth. Participants were asked to recall the instructions immediately after the session, and again after a 1-week delay. Overall, the number of details recalled was significantly lower when instructions were provided by telehealth, both immediately after the session and after a 1-week delay. It is likely that a mix of technological and communication strategies by the healthcare provider could reduce this telehealth memory deficit. Given the rapid transition to telehealth due to COVID-19, highlighting this deficit and providing potential solutions are timely and of utmost importance. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.1 (2000) vii-ix [Access article in PDF] In Memory of Henry I first met Henry W. Johstone Jr. during the spring of 1968. I was a doctoral candidate at the University of Wisconsin and Henry was in Madison as part of a distinguished visitor series hosted by my mentor, Lloyd Bitzer. Lloyd had invited a group of graduate students to his home to meet the (...) guest of honor. I was particularly excited because Henry had accepted my paper on Aristotle's theory of exemplification to appear in the new international journal Philosophy and Rhetoric, which he edited. This was my first publication and I wanted to thank him, which seemed to this novice the appropriate thing to do. I remember that evening for Henry's seeming reserve, which I later learned was a deep shyness that masked his capacity for uncanny directness and a wicked sense of humor, and for his generosity in deflecting my naiveté about the basis for editorial judgments. I also remember it for his deft way of engaging a room of young rhetoricians with questions that conveyed his doubt about their subject (he later changed his mind) without clouding his sincere openness to what we had to say. The following fall, we met again during my interview for a position in the Speech Department at Penn State University. I was offered the position and became Henry's colleague as Book Review Editor of P&R. For the next thirty years, I was blessed to serve as Henry's partner-in-crime in the joys of life that may remain today only among the professoriate. We shared in the editorial work of the journal, in co-teaching our graduate seminar in Philosophy and Rhetoric, in our intellectual passion for the bonds and wars between philosophy and rhetoric, and in the pleasure of choosing the right bottle of wine. But more than that, we shared these common pursuits in contexts of luncheons, dinners, and social occasions that mixed intellectual work with the pleasure of treasured company.My son phoned today to tell me that Henry had died. His passing leaves a void in my life that goes beyond the loss of a friend and colleague. Henry was the person who, through patient selection of manuscripts for me to referee and guidance, taught me how to read journal submissions and offer critiques that might help the author to improve and the journal to prosper. Henry was the person who taught me the value of generosity with junior colleagues by his respectful and serious engagement of my own work. He had a marvelous capacity to entertain any idea seriously, to consider the possibility that even a far-fetched conjecture might have value rather than rejecting it out of hand. He lived the ideas he wrote about as a philosopher, arguing always ad hominem and con amore. Henry was the person who took me in tow as a young Turk and suffered my impatience with the conservative ways of our established institution [End Page vii] by taking me to lunch, engaging me in discussions of ideas, and sharing the delights of intellectual work, and in the process helping me retain my ideals and my focus.Lunch for Henry was more than a noontime meal. It was the way he sustained bonds with those he valued as friends and colleagues. He would call two weeks in advance to arrange a date at the Allen Room of the State College Hotel. He would arrive at my office ten minutes early and we would take a leisurely stroll along the Old Main Mall to the hotel. Our arrival was announced by the host with "Good afternoon Dr. Johnstone," that showed in its formality deep respect and in its tone equally deep affection. Henry always took a cocktail with lunch, inviting his companion to join him, and unless you were specific about the bill beforehand, Henry usually insisted on paying. Settling the bill was never an issue for Henry. He often included a graduate assistant from the journal or an assistant professor in our party and seemed to... (shrink)

Developmental dyslexia hinders reading and writing acquisition of around 5-10 % of the children all over the world. However, little is known about role of prospective memory among dyslexics. Prospective memory is realization of delayed intention. Realization of delayed intention requires self initiated process. The present study explored the role of memory (prospective and retrospective memory), meta-memory and attention among dyslexic’s children. One hundred and fifteen children (51 dyslexics and 64 normal controls) participated in the (...) study. Prospective and retrospective memory questionnaire, everyday attention questionnaire and meta-memory were administered on children. Analysis of variance was used to analyses the data. All the main effects were significant. Some interactions were also found to be significant. Results suggest that dyslexic’s performance on memory (prospective and retrospective memory) was worse than normal control. Meta-memory influences both dyslexics and normal control on prospective and retrospective memory. However, meta-memory affected dyslexics much more than normal control group. Similarly, significant differential effects were observed for simple, difficult and mixed attentional condition among between dyslexics and normal control. Dyslexic’s performance was deteriorated as compared to normal control group. The findings of the study are discussed in the light of the existing literature. Keywords: Meta-memory, Phoneme, Phonological awareness,and Visuo-spatial sktechpad. (shrink)

The emotions that people experience in day-to-day social situations are often mixed emotions. Although autobiographical recall is useful as an emotion induction procedure, it often involves recalling memories associated with a specific discrete emotion. However, real-life emotions occur freely and spontaneously, without such constraints. To understand real-life emotions, the present study examined characteristics of emotions that were elicited by recalling “stressful interpersonal events in daily life” without the targeted evocation of a specific discrete emotion. Assuming generation of mixed and complex (...) emotions, emotional groups with relatively strong correlation of multiple emotions according to surprise, fear, anger, disgust, sadness, and happiness were expected. Seventy-two university students participated in the study. In the emotion induction procedure, participants freely recalled memories as per the instructions on a monitor, and then responded silently to a series of questions concerning any one recalled incident. Assessments of emotional states using emotion scales and another item indicated that validated emotional changes had occurred during the task. Inter-correlations between six emotions demonstrated an emotional group consisting of disgust and anger, which frequently occur as negative interpersonal feelings, and that of fear and sadness. This indicated generation of mixed and complex emotions as experienced in social life. Future studies concerning relationships between these emotions and other factors, including neurophysiological responses, may facilitate further understanding about relationships between mental and physiological processes occurring in daily life.

This paper presents the findings of an ultrasound study of ten New Zealand English and ten Tongan -speaking trombone players, to determine whether there is an influence of native language speech production on trombone performance. Trombone players’ midsagittal tongue positions were recorded while reading wordlists and during sustained note productions. After normalizing to account for differences in vocal tract shape and ultrasound transducer orientation, we used generalized additive mixed models (GAMMs) to estimate average tongue shapes used by the players from (...) the two language groups when producing notes at different pitches and intensities, and during the production of the monophthongs in their native languages. The average midsagittal tongue contours predicted by our models show a statistically robust difference at the back of the tongue distinguishing the two groups, although tongue shape during playing does not directly map onto vowel tongue shapes as prescribed by the pedagogical literature. While the New Zealand English-speaking participants employed a playing tongue position approximating the neutral vowel schwa and vowel used in the word ‘lot’, the Tongan participants used a tongue shape loosely patterning with the back vowels /o/ and /u/. We argue that these findings represent evidence for native language influence on brass instrument performance; however, this influence seems to be secondary to more basic constraints of brass playing related to airflow requirements and acoustical considerations, with the vocal tract configurations observed across both groups satisfying these conditions in different ways. Our findings furthermore provide evidence for the functional independence of various sections of the tongue and indicate that speech production, itself an acquired motor skill, can influence another skilled behavior via motor memory of vocal tract gestures forming the basis of local optimization processes to arrive at a suitable tongue position for sustained note production.

Covid-19 brought back memories of past pandemics. In society, a pandemic imaginary was installed, framing an imaginary landscape, alongside a rationalized pandemic intellect to which the media contributed a lot. We live immersed in tele technologies, adding present to the past and past to the present. At a time when home confinement became the rule, this was even more highlighted. In this screen technological Era, social practices were even more subject to the five great sociotechnical effects that condition information and (...) the way it articulates memory and the present: ubiquity, instantaneity, acceleration, mobilization and presentism. This article intends to demonstrate the presence of the imaginary of past pandemics in the present (Applying Einstein's Theory of General Relativity), the way in which we appropriate these memories to create solutions and the way in which we mix the present with the solutions that came from the past.

People frequently gesture when a word is on the tip of their tongue (TOT), yet research is mixed as to whether and why gesture aids lexical retrieval. We tested three accounts: the lexical retrieval hypothesis, which predicts that semantically related gestures facilitate successful lexical retrieval; the cognitive load account, which predicts that matching gestures facilitate lexical retrieval only when retrieval is hard, as in the case of a TOT; and the motor movement account, which predicts that any motor movements should (...) support lexical retrieval. In Experiment 1 (a between‐subjects study; N = 90), gesture inhibition, but not neck inhibition, affected TOT resolution but not overall lexical retrieval; participants in the gesture‐inhibited condition resolved fewer TOTs than participants who were allowed to gesture. When participants could gesture, they produced more representational gestures during resolved than unresolved TOTs, a pattern not observed for meaningless motor movements (e.g., beats). However, the effect of gesture inhibition on TOT resolution was not uniform; some participants resolved many TOTs, while others struggled. In Experiment 2 (a within‐subjects study; N = 34), the effect of gesture inhibition was traced to individual differences in verbal, not spatial short‐term memory (STM) span; those with weaker verbal STM resolved fewer TOTs when unable to gesture. This relationship between verbal STM and TOT resolution was not observed when participants were allowed to gesture. Taken together, these results fit the cognitive load account; when lexical retrieval is hard, gesture effectively reduces the cognitive load of TOT resolution for those who find the task especially taxing.

AimsIn this pilot mixed-methods study, we examined the participants experiences of engaging in virtual drawing tasks and the impact of an olfactory stimulus on outcomes of affect, stress, self-efficacy, anxiety, creative agency, and well-being.MethodsThis study used a parallel mixed-methods, simple block randomization design. The study participants included 24 healthy adults aged 18 to 54 years, including 18 women and six men. The participants completed two 1-h immersive virtual art making sessions and were randomly assigned to receive either a fragrance or (...) a non-fragrance condition for the first session. Quantitative and qualitative datasets were collected concurrently and integrated during data analysis.ResultsThe quantitative results indicated that the fragrance condition demonstrated a significant reduction in negative affect, namely, reduced feelings of negativity when compared to the non-fragrance condition. A trend toward improvement in self-efficacy was also seen in the fragrance condition. No significant changes were found for fragrance or non-fragrance conditions for positive affect, anxiety, and creative agency. The qualitative findings included five themes related to art making experiences in virtual reality in both conditions: fun and joy; novelty of virtual media, experimentation, and play; relaxation and calm; learning curve; and physical discomfort and disorientation. Four themes were identified for virtual art content and visual qualities: nature imagery, references to memories and personal symbols, fantasy and play within imagery, and depiction of everyday objects.ConclusionsOverall, the participants reported positive responses to the novel virtual art making experiences which were further heightened by the inclusion of the fragrance stimulus for negative affect. These preliminary findings need to be replicated with larger sample sizes to confirm the outcomes and the trends that were seen in this pilot study. Further research is recommended to examine the differences between experiences of virtual and traditional art media and to examine different olfactory stimuli promoting focus and concentration.

In recent years, there has been an increasing interest in the role of collective memory in ethno-national projects. In addition, there has been an expansion of research utilising memory work and auto/biographical methods, which have been particularly effective in the writing of feminists of colour. The paper is prompted by a return to Avtar Brah's ‘The Scent of Memory’ that it uses as a starting point to explore the relationships between competing accounts of ‘private’ memories of racialisation (...) that come from mixed-race siblings growing up in a mainly white town. Drawing on interviews, the paper uses familial narratives and their individual telling, to show how sense is made of divergent experiences and memories of childhood and teenage in 1960s and 1970s Britain. The paper shows how narrative accounts are often negotiated through multiple senses, revealing them as both imagined and recalled, contested and negotiated. The paper considers the strengths and limitations of narrative analysis in understanding the relationship between individual and collective memories at both national and familial levels. It argues that the ways in which the social and personal memories are connected in the processes of subjectivation are unstable and opaque, and can only ever be partially known through the process of narrativisation.

Substantial evidence indicates that cognitive training can be efficacious for older adults, but findings regarding training-related brain plasticity have been mixed and vary depending on the imaging modality. Recent years have seen a growth in recognition of the importance of large-scale brain networks on cognition. In particular, task-induced deactivation within the default mode network is thought to facilitate externally directed cognition, while aging-related decrements in this neural process are related to reduced cognitive performance. It is not yet clear whether task-induced (...) deactivation within the DMN can be enhanced by cognitive training in the elderly. We previously reported durable cognitive improvements in a sample of healthy older adults who completed 6 weeks of process-based object-location memory training compared to an active control training group. The primary aim of the current study is to evaluate whether these cognitive gains are accompanied by training-related changes in task-related DMN deactivation. Given the evidence for heterogeneity of the DMN, we examine task-related activation/deactivation within two separate DMN branches, a ventral branch related to episodic memory and a dorsal branch more closely resembling the canonical DMN. Participants underwent functional magnetic resonance imaging while performing an untrained object-location memory task at four time points before, during, and after the training period. Task-induced activation values were extracted for the ventral and dorsal DMN branches at each time point. Relative to visual fixation baseline: the dorsal DMN was deactivated during the scanner task, while the ventral DMN was activated; the object-location memory training group exhibited an increase in dorsal DMN deactivation relative to the active control group over the course of training and follow-up; changes in dorsal DMN deactivation did not correlate with task improvement. These results indicate a training-related enhancement of task-induced deactivation of the dorsal DMN, although the specificity of this improvement to the cognitive task performed in the scanner is not clear.

This paper is a tentative step towards a historical cognitive science, in the domain of memory and personal identity. I treat theoretical models of memory in history as specimens of the way cultural norms and artifacts can permeate ('proto')scientific views of inner processes. I apply this analysis to the topic of psychological control over one's own body, brain, and mind. Some metaphors and models for memory and mental representation signal the projection inside of external aids. Overtly at (...) least, medieval and Renaissance theorists agreed that such models had to allow for, or even guarantee, some conception of cognitive order and discipline. Individual memory traces had to be independent, not mixed up or interfering with others. The long tradition of improving or bypassing 'natural memory' by deliberately internalizing artefactual models was part of an arduous process of self-fashioning. Moral panic about confusion and mixture features centrally in the imposition of cognitive discipline in local memory traditions. (shrink)

Multicarrier systems, such as car batteries and semiconductors, have surprisingly complex transport properties. Even for steady-state transport, one can find counterexamples to standard assumptions about local electroneutrality, constancy in space of the electric field, linearity in space of the voltage, and the relationship between dissipation, voltage, and current. Moreover, unless recombination processes occur, boundaries impose conditions that can disturb the response far into the bulk to remove memory of the boundaries. Because the demands of the chemical reactions at the (...) electrodes cannot be satisfied by diffusion alone, car batteries are electrically active even when they are neither charging nor discharging. We offer practical advice on battery care for bike-riders, say, who only occasionally use their cars. For semiconductors, recombination does occur, which in transport enables partial currents to adjust from their surface to their bulk values. For mixed ionic electronic conductors, bulk recombination may be essential to an understanding of “blocking electrodes.” The voltage associated with both current-producing and non-current-producing surface reactions provides a natural explanation for the bioelectric fields observed during root and other growth processes.

Working memory performance affects children’s learning. This study examined objective, subjective, and physiological cognitive load while children completed a spatial working memory complex span task. Frist, 80 Taiwanese 11-year-olds who participated in Experiment 1 confirmed the suitability of the materials. Then, 72 Taiwanese 11-year-olds were assigned to high and low complexity groups to participate in Experiment 2 to test the study hypothesis. Children had to recall at the end of a dual-task list and answer two questions regarding the (...) difficulty and mental effort involved in processing and storage. Their pupil diameters were recorded using an eye-tracker. Two-way mixed ANOVA found that the processing requirements and memory load reduced storage and aggravated the subjective CL of storage; the subjective CL of processing was higher under highly complex conditions. Stepwise regression analysis indicated that subjective CL of processing predicted memory performance in low CL conditions, and physiological CL of processing predicted it in high CL conditions.

BackgroundSexual minority (SM) older adults experience mental health disparities. Psychiatric disorders and neuropsychiatric symptoms (NPS) are risk factors for cognitive decline. Although older people in same-sex (SSR) compared to mixed-sex relationships (MSR) perform more poorly on cognitive screening tests, prior studies found no differences in rates of dementia diagnosis or neuropsychological profiles. We sought to explore the role of NPS on neurocognitive outcomes for SM populations. We compared cognitive performance and structural brain parameters of older adults in SSR and MSR.MethodsData (...) were originally collected at Alzheimer's Disease Research Centers (ADRCs). Inclusion criteria were: age of 55+ years, a study partner identified as a spouse/partner, and availability of T1-MRI brain volumes/thickness. Participants were labeled as either SSR or MSR based on their/their co-participant's reported sex. We identified 1,073 participants (1,037 MSR−555 cognitively unimpaired [CU]; 36 SSR−23 CU) with structural MRI data, Mini-Mental State Exam (MMSE), and Neuropsychiatric Inventory Questionnaire (NPI-Q) scores. A subset of the overall sample completed comprehensive neuropsychological assessment (n = 939; 908 MSR−494 CU; 31 SSR−22 CU). Covariates included in statistical models were age, sex, education, total intracranial volume, and apolipoprotein E genotype.ResultsMultivariate general linear models showed significant diagnosis-by-relationship interaction effects on the left parahippocampal gyrus volume. After stratification by relationship group, only cognitively impaired (CI) MSR had significantly smaller left parahippocampal volumes than MSR-CU. The SSR group showed better episodic memory performance. Severity of neuropsychiatric symptoms was negatively associated with volume/thickness of bilateral fronto-temporal areas and with MMSE scores, predominantly in the MSR group.ConclusionIn our study, MSR participants presented with a more compromised cognitive profile than SSR participants. MSR-CI participants showed significantly smaller left medio-temporal volumes, a neural signature of AD. Neuropsychiatric symptoms predicted smaller fronto-temporal volumes in the MSR more consistently than in the SSR group. These findings may be due to unexplored protective factors against cognitive decline in SM elders. Indeed, social support has been proposed as a protective factor warranting future investigation.

Reasoning may help solving problems and understanding personal experiences. Ruminative reasoning, however, is inconclusive, repetitive, and usually regards negative thoughts. We asked how reasoning as manifested in oral autobiographical narratives might differ when it is ruminative versus when it is adaptive by comparing two constructs from the fields of psychotherapy research and narrative research that are potentially beneficial: innovative moments (IMs) and autobiographical reasoning (AR). IMs captures statements in that elaborate on changes regarding an earlier personal previous problem of the (...) narrator, and AR capture the connecting of past events with other parts of the narrator’s life or enduring aspects of the narrator. A total ofN= 94 university students had been selected from 492 students to differ maximally on trait rumination and trait adaptive reflection, and were grouped as ruminators (N= 38), reflectors (N= 37), and a group with little ruminative and reflective tendencies (“unconcerned,”N= 19). Participants narrated three negative personal experiences (disappointing oneself, harming someone, and being rejected) and two self-related experiences of more mixed valence (turning point and lesson learnt). Reflectors used more IMs and more negative than positive autobiographical arguments (AAs), but not more overall AAs than ruminators. Group differences were not moderated by the valence of memories, and groups did not differ in the positive effect of narrating on mood. Trait depression/anxiety was predicted negatively by IMs and positively by AAs. Thus, IMs are typical for reflectors but not ruminators, whereas the construct of AR appears to capture reasoning processes irrespective of their ruminative versus adaptive uses. (shrink)

It is about analyzing the connection between just memory, narration and art, using an approach that mixes philosophy and visual arts. We will start from the perspective of the French philosopher Paul Ricoeur on fair memory, presented in his work Memory, History, Oblivion (2000), according to which there is an institutionalized ideologization of memory in which narrations are silenced or distorted by the so-called official history. In the process of recovering fair memory, these narratives need (...) to be heard, recognized and valued, deconstructing abusive mechanisms that silence them with the aim of producing oblivion or that manipulate them involve distorting the facts to benefit hegemonic discourses. Next, we will discuss how the myth of Brazilian racial democracy is an example of institutionalized ideologization of memory, considering mainly the reflections of Brazilian philosophy Sueli Carneiro in Device of raciality (2023). Finally, we will show how Elian Almeida's pictorial counter-narratives, especially the Vogue series (2020), work to strengthen and disseminate unofficial narratives about Brazil that have been suffocated by official history.

Objectives: Mental disorders are vastly underdiagnosed in low-income countries that disproportionately affect women. We aimed to evaluate the prevalence of common mental disorders in newly postpartum women, and stigma associated with mental health reporting in an Ethiopian community using a validated World Health Organization survey.Methods: The Self Reporting Questionnaire for psychological distress was administered in Amharic by nurses to 118 women aged 18–37 years who had given birth in the prior 3 months in the Glenn C. Olsen Memorial Primary Hospital (...) in Yetebon. Mental health stigma among the four nursing staff was assessed using Link and Phelan's Components of Stigma.Results: Among 118 women surveyed, 18% had a probable common mental disorder using the SRQ 4/5 cutoff and 2% admitted to suicidal thoughts. Presence of stigma in the healthcare staff was verified, including labeling, stereotyping, separating, and status loss and discrimination.Conclusion: Postpartum mental health disorders as well as stigma against such diagnoses are common in the Yetebon community. There is an urgent need for increased availability of properly trained and supervised healthcare staff in the identification and referral of postpartum women with common mental disorders. (shrink)

Findings suggest a positive impact of bilingualism on cognition, including the later onset of dementia. However, it is not clear to what extent these effects are influenced by variations in attentional control demands in response to specific task requirements. In this study, 20 bilingual and 20 monolingual older adults performed a task-switching task under explicit task-cuing vs. memory-based switching conditions. In the cued condition, task switches occurred in random order and a visual cue signaled the next task to be (...) performed. In the memory-based condition, the task alternated after every second trial in a predictable sequence without presenting a cue. The performance of bilinguals did not vary across experimental conditions, whereas monolinguals experienced a pronounced increase in response latencies and error rates in the cued condition. Both groups produced similar switch costs and mixing costs, but bilinguals produced them with lower response latencies. The cognitive benefits of bilingualism seem not to apply to executive functions per se but to affect specific cognitive processes that involve task-relevant context processing. The present results suggest that lifelong bilingualism could promote in older adults a flexible adjustment to environmental cues, but only with increased task demands. However, due to the small sample size, the results should be interpreted with caution. (shrink)

Auditory warnings have been shown to interfere with verbal working memory. However, the impact of different types of auditory warnings on working memory tasks must be further researched. This study investigated how different kinds of auditory warnings interfered with verbal and spatial working memory. Experiment 1 tested the potential interference of auditory warnings with verbal working memory. Experiment 2 tested the potential interference of auditory warnings with spatial working memory. Both experiments used a 3 × (...) 3 mixed design: auditory warning type was between groups, and task condition was within groups. In Experiment 1, earcons and spearcons but not auditory icons worsened the performance on the verbal serial recall task in the identify-warning condition, compared with that in the no-warning or ignore-warning conditions. In Experiment 2, only identifying earcons worsened the performance on the location recall task compared with performance without auditory warnings or when auditory warnings were ignored. Results are discussed from the perspective of working memory resource interference, and their practical application in the selection and design of auditory warning signals is involved. (shrink)

This essay deals with Nina Bouraoui’s mixed-race identity as presented in her autobiographical novels Garçon manqué and Mes mauvaises pensées. The métis question takes the shape of a representation of an ethnicized, dual and fractured identity. My argument explores a contradiction at work in Bouraoui’s texts: while reclaiming the existence of a Franco-Algerian métis identity, Bouraoui represents the métis as the incarnated perpetuation of the historical tensions that divided France and Algeria. The narratives simultaneously construct and deconstruct Bouraoui’s Franco-Algerian métis (...) identity. I examine how Bouraoui represents her Algerian legacy and appropriates a familial history to construct herself as Algerian. I analyze how traumatic memories of asphyxiation are a metaphor for Bouraoui’s difficult relationship with her French self, symbolized by the motif of white skin. And I consider how the ends of the two novels provide a problematic acceptance and fulfillment of Bouraoui’s métis identity. (shrink)

Previous studies have demonstrated that lying can undermine memory and that its memory-undermining effects could be modulated by the cognitive resources required to tell lies. We extended the investigation of the memory-undermining effect by using a daily life setting in which participants were highly involved in a mock shopping task. Participants were randomly assigned to truth-telling, denying or mixed lying conditions. After finishing the shopping task, participants were told that two people wanted to know about their shopping (...) lists and would ask them some questions in an interview. During the interview, participants were asked whether each of ten items were on the shopping list, five of which were randomly selected from the shopping list, while the other five were not sold in the store. In answering the interview questions, the truth-telling group was asked to respond honestly, the denying group was asked to give denial responses, and the mixed lying group was asked to respond deceptively. Thus, the denying group told five lies and the mixed lying group told ten lies in the interview. The item memory test, source memory test and destination memory test were given in an orderly manner 48 h after the interview. We found that the mixed lying group, rather than the denying group, forgot the lies they told in the interview and mistakenly believed they had lied about something that they had not lied about. Moreover, the mixed lying group retained fewer memories about the person they responded to than the honest group. In addition, participants in the mixed lying group had more non-believed memories than those in the truth-telling group in both item and source memory tests. We conclude that more lies could result in more memory disruptions in daily life. (shrink)

Tactile exploration often involves sequential touches interspersed with stimulus-free durations. Whereas it is obvious that texture-related perceptual variables, irrespective of the encoding strategy, must be stored in memory for comparison, it is rather unclear which of those variables are held in memory. There are two established variables—“intensity” and “frequency”, which are “temporally global” variables because of the long stimulus integration interval required to average the signal or derive spectral components, respectively; on the other hand, a recently established third (...) contender is the “temporally local” variable that codes for kinematic profiles of very short, suprathreshold events in the vibrotactile signal. Here, we present the first psychophysical evidence that temporally local variables can be stored in memory. To that end, we asked participants to detect changes in pulsatile indentation stimuli at their fingertips with and without a gap of 1 s between stimulus presentations. The stimuli either contained global variables alone, or a mix of local and global variables. We found, first, that humans are much better at detecting a change in stimuli when local variables are available rather than global ones alone—as evident by the fact that 21 compared to only 6 participants out of 25 yielded a valid psychophysical curve, respectively. Second, this observation persists even when there is a gap between the stimuli, implying local variables must be stored in memory. Third, an extensive array of relevant intensity definitions failed to explain participants’ performance in any consistent manner, which implies that perceptual decisions were less likely to be driven by intensity coding. Taken together, our results suggest that humans perform pulsatile change detection utilizing local pulse shape, and to a lesser degree global pulse rate, and that both parameters can be stored in memory.

We introduce a new and time-efficient memory-encoding paradigm for functional magnetic resonance imaging. This paradigm is optimized for mapping multiple contrasts using a mixed design, using auditory and visual stimuli. We demonstrate that the paradigm evokes robust neuronal activity in typical sensory and memory networks. We were able to detect auditory and visual sensory-specific encoding activities in auditory and visual cortices. Also, we detected stimulus-selective activation in environmental-, voice-, scene-, and face-selective brain regions. A subsequent recognition task allowed (...) the detection of sensory-specific encoding success activity in both auditory and visual cortices, as well as sensory-unspecific positive ESA in the hippocampus. Further, sensory-unspecific negative ESA was observed in the precuneus. Among others, the parallel mixed design enabled sustained and transient activity comparison in contrast to rest blocks. Sustained and transient activations showed great overlap in most sensory brain regions, whereas several regions, typically associated with the default-mode network, showed transient rather than sustained deactivation. We also show that the use of a parallel mixed model had relatively little influence on positive or negative ESA. Together, these results demonstrate a feasible, versatile, and brief memory-encoding task, which includes multiple sensory stimuli to guarantee a comprehensive measurement. This task is especially suitable for large-scale clinical or population studies, which aim to test task-evoked sensory-specific and sensory-unspecific memory-encoding performance as well as broad sensory activity across the life span within a very limited time frame.

Allocating attention determines what we remember later. Attentional demands vary in a task-switching paradigm, with greater demands for switch than for repeat trials. This also results in lower subsequent memory performance for switch compared to repeat trials. The main goal of the present study was to investigate the consequences of task switching after a long study-test interval and to examine the contributions of the two memory components, recollection and familiarity. In the study phase, the participants performed a task-switching (...) procedure in which they had to switch between two classifications tasks with pictures. After a short vs. a long study-test interval of a week, the participants performed a surprise memory test for the pictures and gave remember/know judgements. The results showed that recognition memory declined after 1 week and this was mainly due to a decrease in “remember” responses. The results also showed that the task-switching effect on memory was enduring. Whereas the results of the immediate test were mixed, the results of the delayed tests showed that the task-switching effect was based on recollection, expressed in more “remember” responses for repeat than for switch trials. As recollection is more sensitive to attention manipulations than familiarity, the results align with the notion that attentional requirements at study determine what we remember, in particular after a long study-test interval.

“Pale Blue Dot” and “Anthropocene” are common tropes in astrobiology and often appear in ethical arguments. Both support a decentering of human life relative to biological life in terms of value. This article introduces a typology of life-value narratives: hierarchical narratives with human life above other life and holistic narratives with human life among other life. Astrobiology, through the two tropes, supports holistic narratives, but this should not be viewed as opposed to Christianity. Rather, Christian scriptures provide seeds of both (...) hierarchical and holistic narratives, each of which may flourish in different environments. By attending to which aspects of human life are valued—or disvalued—relative to biological life, we can better understand how life-concepts do work in ethics, anthropology, and soteriology in secular as well as theological contexts.

For a long while the dilemma between ‘not being’ and ‘being other’ has haunted the history of Brazil. The country's mixed-race condition lay at the heart of the dilemma which reached its apogee in the second half of the nineteenth and the beginning of the twentieth centuries. At that point in its history, that is, its emergence as a nation-state, the construction of a national identity became an imperative for the political and intellectual elites of Brazil. In this context, a (...) European, the German naturalist, Carl von Martius, made himself particularly notable for having been one of the first, after Independence, to point out the significance of miscegenation in the composition of Brazilian identity.

The state of Alaska has a complex historical relationship with its wild wolf packs. The authors expand Connell's concept of frontier masculinity to interpret articles from the Anchorage Daily News as an alternative way to understand Alaska's shifting wolf policies. Originally, state policies were shaped by frontier masculinity and characterized by claims of sportsmen's rights to kill wolves. With the reinstitution of an aggressive wolf-eradication project, Alaska policy makers retooled frontier masculinity. This altered form of masculinity, retro frontier masculinity, is (...) constructed at the state level and deploys new strategic emphases: vilifying opponents as feminized sissies, casting wolf hunters as paternalist protectors, reifying the masculine family provider role, and framing the issue as fundamentally about competition.

Both Aristotle and Ernst Mayr present theories of dual explanation in biology, with proximal, clearly physical explanations and more distal, biology-specific explanations. Aristotle’s presentation of final cause explanations in Posterior Analytics relates final causes to the necessary material, formal, and efficient causes that mediate them. Johnson and Leunissen demonstrate the problematic nature of historical and recent interpretations and open the door for a new interpretation consistent with modern evolutionary theory. Mayr’s differentiation of proximate and ultimate/evolutionary causes provides a key to (...) appropriating Aristotle for modern use, if care is taken to differentiate Mayr’s proximate/distal and mechanical/evolutionary distinctions from his intentional/non-intentional distinction. Building on Mayr, and noting his appropriation of ancient and recent commentary, a strong case can be made for nested explanation, wherein evolutionary explanations are instantiated in systems of mechanical explanations. Biological concepts of organism, gene, function, etc., are etiologically prior to mechanical explanations of function, but temporally posterior to mechanical explanations of historical adaptation. Such an analysis sheds light on recent arguments within evolutionary biology while highlighting the importance of epistemology in contemporary science. (shrink)

The primary challenge for generating a useful scientific definition of life comes from competing concepts of biological activity and our failure to make them explicit in our models. I set forth a three-part scheme for characterizing definitions of life, identifying a binary , a range , and a preference . The three components together form a proper activity in biology . To be clear, I am not proposing that proper activity be adopted as the best definition of life or even (...) as a desirable definition for life. Instead, I am arguing that some notion of proper activity already exists within common scientific definitions. By making the implicit elements explicit, the notion can be analyzed to see whether it is useful and appropriate in the context of the biological sciences. (shrink)

Rips et al. raise important questions about the relation between infant quantification and achievement of natural number concepts. However, they may be oversimplifying the interactions that characterize actual development in real time. Though they propose a worthwhile agenda for future research, its explanatory power will be limited if it does not address developmental issues with greater sensitivity.

These commentaries will obviously be of interest to students of Aquinas. They should also be of interest to students of Aristotle, but with one caveat. The translators have had the delicate task of rendering into English not Aristotle’s Greek but the Latin translation of it on which Aquinas is commenting. As the Latin translates Aristotle on something close to a word-for-word basis, so the translators have translated the Latin version of Aristotle into English almost word-for-word. Further, as Macierowski explains, they (...) have taken care to preserve the opacity of terms that Aquinas explains in his commentary; to have clarified these opaque terms in the initial translation of Aristotle’s text would have made Aquinas’s later clarifications nugatory. The rationale is clear and the policy defensible, but the resulting translation of Aristotle can be rough going, for example, “for it is not just from a distance, and not close up, that one of the mixed colors appears, but from anywhere” ; “Therefore they seek in this way, and, not seeking, they still recollect in this way, when that motion comes into being after the other one; but it used to come about when the other motions such as we have.

This paper is a critical examination of Harry Collins's investigation into a third form of knowledge, “interactional expertise.” We argue that although Collins makes a genuine contribution to the phenomenological literature on expertise, his account requires further critical evaluation and response due to pragmatic and ontological considerations. We contend that by refining (in some questionable ways) the category of interactional expertise so as to create epistemological equivalence between activists, sociologists, critics, journalists, and some science administrators, Collins potentially undermines the value (...) that a more rigorously construed concept of interactional expertise might have. We further show that Collins misunderstands the nature of embodiment in a way that is exacerbated by the sociological perspective that he adopts. (shrink)
