CYBATHLON is an international championship where people with severe physical disabilities compete with the aid of state-of-the-art assistive technology. In one of the disciplines, the BCI Race, tetraplegic pilots compete in a computer game race by controlling an avatar with a brain-computer interface. This competition offers a perfect opportunity for BCI researchers to study long-term training effects in potential end-users, and to evaluate BCI performance in a realistic environment. In this work, we describe the BCI system designed by the (...) team Mirage91 for participation in the CYBATHLON BCI Series 2019, as well as in the CYBATHLON 2020 Global Edition. Furthermore, we present the BCI’s interface with the game and the main methodological strategies, along with a detailed evaluation of its performance over the course of the training period, which lasted 14 months. The developed system was a 4-class BCI relying on task-specific modulations of brain rhythms. We implemented inter-session transfer learning to reduce calibration time, and to reinforce the stability of the brain patterns. Additionally, in order to compensate for potential intra-session shifts in the features’ distribution, normalization parameters were continuously adapted in an unsupervised fashion. Across the aforementioned 14 months, we recorded 26 game-based training sessions. Between the first eight sessions, and the final eight sessions leading up to the CYBATHLON 2020 Global Edition, the runtimes significantly improved from 255 ± 23 s to 225 ± 22 s, respectively. Moreover, we observed a significant increase in the classifier’s accuracy from 46 to 53%, driven by more distinguishable brain patterns. Compared to conventional single session, non-adaptive BCIs, the inter-session transfer learning and unsupervised intra-session adaptation techniques significantly improved the performance. This long-term study demonstrates that regular training helped the pilot to significantly increase the distance between task-specific patterns, which resulted in an improvement of performance, both with respect to class separability in the calibration data, and with respect to the game. Furthermore, it shows that our methodological approaches were beneficial in transferring the performance across sessions, and most importantly to the CYBATHLON competitions. (shrink)

ABSTRACT:U.S. Organizational Sentencing Guidelines provide firms with incentives to develop formal ethics programs to promote ethical organizational cultures and thereby decrease corporate offenses. Yet critics argue such programs are cosmetic. Here we studied bank employees before and after the introduction of formal ethics training—an important component of formal ethics programs—to examine the effects of training on ethical organizational culture. Two years after a single training session, we find sustained, positive effects on indicators of an ethical (...) organizational culture (observed unethical behavior, intentions to behave ethically, perceptions of organizational efficacy in managing ethics, and the firm’s normative structure). While espoused organizational values also rose in importance post-training, the boost dissipated after the second year which suggests perceptions of values are not driving sustained behavioral improvements. This finding conflicts with past theory which asserts that enduring behavioral improvements arise from the inculcation of organizational values. Implications for future research are discussed.

This study evaluated the effects of an exergame program combined with traditional tennis training on autonomic regulation, tennis technique, gross motor skills, clinical reaction time, and cognitive inhibitory control in children. Sixty-three children were randomized into four groups and compared at baseline, 6-month immediately post intervention and at 1-year follow-up post intervention. At 6-month post intervention the combined exergame and regular training sessions revealed: higher breathing frequency, heart rate and lower skin conductance levels during exergaming; additional benefits in (...) the point of contact and kinetic chain elements of the tennis forehand and backhand technique ; negative impact on the shot preparation and the follow-through elements ; higher ball skills ; higher percentages of clinical reaction time improvement and cognitive inhibitory control improvement in both congruent and incongruent trials. The 1-year follow-up test showed no differences in the tennis technique, clinical reaction time and cognitive inhibitory control improvement between groups with the same number of trainings per week. The findings support exergaming as an additional training tool, aimed to improve important cognitive-motor tennis skills by adding dynamics to the standardized training process. Caution should be placed to planning this training, e.g., in a mesocycle, since exergaming might decrease the improvement of specific tennis technique parts of the trainees.. (shrink)

Cognitive control processes, such as updating task-relevant information while switching between multiple tasks, are substantially impaired in older adults. However, it has also been shown that these cognitive control processes can be improved by training interventions, e.g., by training in task switching. Here, we applied an event-related potential approach to identify whether a cognitive training improves task-preparatory processes such as updating of relevant task goals. To do so, we applied a pretest-training-posttest design with eight training (...) sessions. Two groups of older adults were either trained in task switching or in performing single tasks and we compared their performance to a group of untrained younger adults. To foster cue updating in the treatment group, we applied a cue-based switching task in which the two task cues were randomly selected prior to target presentation so that participants had time to prepare for the upcoming task. In contrast, the control group also received task cues but those were redundant as only one task had to be performed. We also examined whether training in cue updating during task switching can be transferred to a similar cognitive control task measuring updating of context information, namely a modified version of the AX-Continuous Performance Task. The results revealed training-specific improvements in task switching, that is, a larger improvement in blocks requiring switching in comparison to single tasks at the behavioral level. In addition, training specific-effects were also found at the neuronal level. Older adults trained in cue updating while switching showed a reduction in mixing costs in the cue-related P3, indicating an improvement in preparatory updating processes. Additionally, P3 topography changed with training from a very broad to a parietally focused scalp distribution similar to the one found in younger adults. However, we did not obtain training-specific improvements in context updating in the AX-CPT neither at the behavioral level nor at the neuronal level. Results are discussed in the context of the ongoing debate on whether transfer of cognitive training improvements is possible. (shrink)

Persons with visual impairments (hereafter PVI) detect and discover obstacles and road conditions by touching with a white cane when walking on the streets. In one training session, an Orientation and Mobility specialist (hereafter SPT) guided a PVI by grasping and moving the cane that the PVI was holding. We conducted a multimodal analysis of two instruction sequences, one a "proving and achieving" demonstration (Sacks in Lectures on conversation, Blackwell, 1992) and the other a "learnable" (Zemel and Koschmann, (...) in Discourse Stud 16:163–183, 2014) demonstration. The achieving demonstration proved the assessment of the PVI's performance. In the "learnable" demonstration, the PVI was able to receive and perform the most critical part of the "learnable" of the long contact touch without the aid of talk. Sharing a single cane touch is an efficient way for both the guiding SPT and the guided PVI to jointly experience and understand the environmental features. The SPT did not need to verbally confirm that the guided touch was accountable to the PVI and seemed confident that intersubjectivity with the PVI had been established. A unique form of being with others and achieving intersubjectivity in society was identified. In traditional learning instruction, it has been assumed that the learnable is presented and communicated visually and audibly. However, through guided touch learnable is presented and conveyed effectively in the cases of this paper. It seems that the sense of touch has been considered to be just for the occasion, but this is an example of something that is not just for the occasion but is consequential, that is, usable for further occasions. The data is in Japanese. (shrink)

In a single richly suggestive word, "song," Sessions sums up all the factors—melodic, harmonic, rhythmic, textural, dynamic, articulative—that contribute to what I have called musical line: "Each one of these various aspects derives its functions from the total and indivisible musical flow - the song. . . . [M]usic can be genuinely organized only on this integral basis, and . . . an attempt to organize its so-called elements as separate factors is, at the very best, to pursue abstraction, (...) and, at the worst, to confuse genuine order with something which is essentially chaotic."1 Analysis, whose functions as a valuable tool for the training of composer and performer Sessions has so well explicated and demonstrated, is now all too often called on to justify and to further this essentially unmusical, or at best nonmusical, pursuit of abstraction. Herein lies the explanation for the increasing doubt of the general usefulness of the discipline that Sessions has lately evidenced.2 For the creation and analysis of art are two distinct activities, confused at the artist's peril.

Complex training is a combination training method that alternates between performing high-load resistance training and plyometric training within one single session. The study aimed to examine the effects of CT on lower-limb strength and power of elite female modern pentathlon athletes under the new modern pentathlon format and competition rules. Ten female participants of the national modern pentathlon team completed 8 weeks of RT as followed by 8 weeks of CT, with 2 weeks of (...) break. Then, the participants conducted 8 weeks of CT, which included RT combined with plyometric training. All stages of training were designed by the linear strength training period theories, requiring participants to train twice for the first 4 weeks and three times for the second 4 weeks. The one-repetition maximum of squat, isometric mid-thigh pull, counter-movement jump, squat jump, pre-stretch augmentation percentage, and reaction strength index were assessed before and after both RT and CT training. One-way repeated-measure ANOVA models revealed that the 1RM of squat was significantly improved after RT as compared to pre-RT. No significant improvement in IMTP, CMJ, SJ, PSAP, and RSI was not observed. After CT, 1RM of squat, IMTP, CMJ, SJ, RSI were significant improved as compared to pre-RT, post-RT and pre-CT, while significant improvements in PSAP were observed as compared to pre-RT and pre-CT, but not to post-RT. This pilot study showed the promise of CT following RT to improve lower-limb strength and power in elite female modern pentathlon athletes. The findings are worthwhile to be confirmed in future studies with larger sample size and randomized design. (shrink)

In resistance training, the use of predicting proximity to momentary task failure, and repetitions in reserve scales specifically, is a growing approach to monitoring and controlling effort. However, its validity is reliant upon accuracy in the ability to predict MF which may be affected by congruence of the perception of effort compared with the actual effort required. The present study examined participants with at least 1 year of resistance training experience predicting their proximity to MF in two different (...) experiments using a deception design. Within each experiment participants performed four trials of knee extensions with single sets to their self-determined repetition maximum and MF. For the first experiment participants used loads equal to 70% of a one repetition maximum performed in a separate baseline session. Aiming to minimize participants between day variability in repetition performances, in the second separate experiment they used loads equal to 70% of their daily isometric maximum voluntary contraction. Results suggested that participants typically under predicted the number of repetitions they could perform to MF with a meta-analytic estimate across experiments of 2.0 [95%CIs 0.0 to 4.0]. Participants with at least 1 year of resistance training experience are likely not adequately accurate at gauging effort in submaximal conditions. This suggests that perceptions of effort during resistance training task performance may not be congruent with the actual effort required. This has implications for controlling, programming, and manipulating the actual effort in resistance training and potentially on the magnitude of desired adaptations such as improvements in muscular hypertrophy and strength.

Previous work has shown that concerns of breast cancer patients after finishing radiotherapy are responsive to conversations with radiographers during the treatment period. This study seeks to further understand radiographer and patient experiences, determine shared priorities for improvement in clinical interaction and develop communication guidelines and training to help radiographers support patients.Methods: Using the principles of Experience-Based Co-Design, semi-structured interviews were held with N = 4 patients and N = 4 radiographers, followed by feedback events to validate findings. Patients (...) and radiographers exchanged experiences in a joint co-design session, agreed with shared priorities and generated ideas for further support. A survey was conducted for process evaluation. To scale up findings, UK-wide representatives from patient networks and radiographers and managerial staff provided consultative input utilizing an iterative, adaptive procedure.Results: Radiographers expressed a need for support with “difficult conversations,” especially those on Fear of Cancer Recurrence, and their appropriate management. Important pointers for reassuring communication were identified, including: being treated like a person, knowing what to expect, and space to ask questions. The co-design process was rated positively by both staff and patients. Thematic collation of findings and mapping these on literature evidence resulted in the “KEW” communication guidelines for radiographers: Know, Encourage, Warmth. National stakeholder consultations validated and helped fine-tune the training model. The resulting training package, included: trigger videos, a simulated patient scenario and interactive handouts on fears of cancer recurrence and the patient pathway.Conclusions: The co-design process captured good practice to help standardize quality in empathic communication in the radiotherapy service. The resulting KEW: Know, Encourage, Warmth guidelines, and training package are user-centered as well as evidence-based. Supplementing single-site co-design with national consultative feedback allows for the development of interventions that are relevant to the clinical practice, even in detail, and helps to generate appropriate buy-in for roll out on a wider scale after evaluation.Trial Registration:www.ClinicalTrials.gov ID: NCT03468881.

Police officers often encounter potentially dangerous situations in which they strongly rely on their ability to identify threats quickly and react accordingly. Previous studies have shown that practical experience and targeted training significantly improve threat detection time and decision-making performance in law enforcement situations. We applied 90-min traditional firearms training as a control condition and a specifically developed intervention training to police cadets. The intervention training contained theoretical and practical training on tactical gaze control, situational (...) awareness, and visual attention, while the control training focused on precision and speed. In a pre- and posttest, we measured decision-making performance as well as response preparation and execution to evaluate the training. Concerning cognitive performance training, the number of correct decisions increased from pre- to posttest. In shoot scenarios, correct decisions improved significantly more in the intervention group than in the control group. In don’t-shoot scenarios, there were no considerable differences. Concerning the training of response preparation and execution in shoot scenarios, the intervention group’s response time, but not hit time, decreased significantly from pre- to posttest. The control group was significantly faster than the intervention group, with their response and hit time remaining constant across pre- and posttest. Concerning the training of tactical action control, the intervention group performed significantly better than the control group. Moreover, the intervention group improved the tactical handling of muzzle position significantly. The results indicate that a single 90-min session of targeted gaze control and visual attention training improves decision-making performance, response time, and tactical handling of muzzle position in shoot scenarios. However, these faster response times do not necessarily translate to faster hit times – presumably due to the motor complexity of hitting an armed attacker with live ammunition. We conclude that theory-based training on tactical gaze control and visual attention has a higher impact on police officers’ decision-making performance than traditional firearms training. Therefore, we recommend law enforcement agencies include perception-based shoot/don’t-shoot exercises in training and regular tests for officers’ annual firearm requalification. (shrink)

It is widely recognized that police performance may be hindered by psychophysiological state changes during acute stress. To address the need for awareness and control of these physiological changes, police academies in many countries have implemented Heart-Rate Variability biofeedback training. Despite these trainings now being widely delivered in classroom setups, they typically lack the arousing action context needed for successful transfer to the operational field, where officers must apply learned skills, particularly when stress levels rise. The study presented here (...) aimed to address this gap by training physiological control skills in an arousing decision-making context. We developed a Virtual-Reality breathing-based biofeedback training in which police officers perform deep and slow diaphragmatic breathing in an engaging game-like action context. This VR game consisted of a selective shoot/don’t shoot game designed to assess response inhibition, an impaired capacity in high arousal situations. Biofeedback was provided based on adherence to a slow breathing pace: the slower and deeper the breathing, the less constrained peripheral vision became, facilitating accurate responses to the in-game demands. A total of nine male police trainers completed 10 sessions over a 4-week period as part of a single-case experimental ABAB study-design. Results showed that eight out of nine participants showed improved breathing control in action, with a positive effect on breathing-induced low frequency HRV, while also improving their in-game behavioral performance. Critically, the breathing-based skill learning transferred to subsequent sessions in which biofeedback was not presented. Importantly, all participants remained highly engaged throughout the training. Altogether, our study showed that our VR environment can be used to train breathing regulation in an arousing and active decision-making context. (shrink)

Maintaining and coordinating multiple task-sets is difficult and leads to costs, however task-switching training can reduce these deficits. A recent study in young adults demonstrated that this training effect occurs at an amodal processing level. Old age is associated with reduced cognitive plasticity and further increases the performance costs when mixing multiple tasks. Thus, cognitive aging might be a limiting factor for inducing cross-modal training effects in a task-switching environment. We trained participants, aged 62–83 years, with an (...) auditory task-switching paradigm over four sessions, to investigate whether training-related reductions in task-switching costs would also manifest in an untrained visual modality version of the task. Two control groups trained with single tasks or not trained allowed us to identify improvements specific to task-switching training. To make statistical evaluations of any age differences in training and cross-modal transfer, the data from the Kattner cohort were incorporated into the present analysis. Despite the tendency for older adults to respond more cautiously, task-switching training specifically led to a mixing cost reduction in both trained and untrained modalities, the magnitude of which was statistically similar regardless of age. In line with a growing body of research, we failed to observe any far transfer effects in measures of inhibition, working memory or fluid intelligence. Overall, we conclude that any apparent cognitive limitations associated with aging do not prevent cognitive control processes which support set-shifting from improving at an amodal level. (shrink)

Although numerous media literacy training sessions on internet safety for children and adolescents have been conducted, their number contrasts sharply with the few systematic studies on their effectiveness. In this study, we describe the evaluation of nationwide-implemented training sessions on internet safety in Luxembourg, which included perceptions of learning outcomes and evaluations of implementation and effectiveness. Training data from 2011 to 2018 were analyzed, including 28,060 students and 5,031 teachers. Students reported pronounced learning effects, especially for younger (...) students and for repeated training participation. Teachers greatly appreciated the implementation and effectiveness, which generally increased over the years. The perceived effectiveness of the training was significantly related to teachers’ planning to cover internet safety topics in future lessons. The present study shows that carefully planned and continuously evaluated training sessions on internet safety successfully support children’s understanding and teachers’ willingness to implement internet safety in their curriculum.

The scientific and practical fields—especially high-performance sports—increasingly request a stronger focus be placed on individual athletes in human movement science research. Machine learning methods have shown efficacy in this context by identifying the unique movement patterns of individuals and distinguishing their intra-individual changes over time. The objective of this investigation is to analyze biomechanically described movement patterns during the fatigue-related accumulation process within a single training session of a high number of repeated executions of a ballistic sports (...) movement—specifically, the frontal foot kick (mae-geri) in karate—in expert athletes. The two leading research questions presented for consideration are (1) Can characteristics of individual movement patterns be observed throughout the entire training session despite continuous changes, i.e., even as fatigue-related processes increase? and (2) How do intra-individual movement patterns change as fatigue-related processes increase throughout a training session? Sixteen expert karatekas performed 606 frontal foot kicks directed toward an imaginary target. The kicks were performed in nine sets at 80% (K-80) of the self-experienced maximal intensity. In addition, six kicks at maximal intensity (K-100) were performed after each of the nine sets. Between the sets, the participants took a 90-s break. Three-dimensional full-body kinematic data of all kicks were recorded with 10 infrared cameras. The normalized waveforms of nine upper- and lower-body joint angles were classified using a supervised machine learning method (support vector machine). The results of the classification revealed a disjunct distinction between the kinematic movement patterns of individual athletes. The identification of unique movement patterns of individual athletes was independent of the intensity and the degree of fatigue-related processes. In other words, even with the accumulation of fatigue-related processes, the unique movement patterns of an individual athlete can be clearly identified. During the training session, changes in intra-individual movement patterns could also be detected, indicating the occurrence of adaptations in individual movement patterns throughout the fatigue-related accumulation process. The results suggest that these adaptations can be modeled in terms of changes in patterns rather than increasing variance. Practical consequences are critically discussed. (shrink)

The aim of this study was to compare the acute effects of performing a lower body resistance training program in one long or two shorter sessions in 1 day on training volume and affective measures. Employing a randomized-crossover design, 23 resistance-trained women performed two training days consisting of one long or two short sessions separated by 3.5–5 h. Each training day was separated by 4-6 days and consisted of three sets to failure for six exercises. (...) class='Hi'>Training volume were recorded during the sessions. Rating of perceived exertion for effort, rating of perceived exertion for discomfort, session displeasure/pleasure and exercise enjoyment were measured 10 min after each session. Participants also completed a readiness to train questionnaire, 24 h after each session, and which training protocol they preferred, 48 h after the last session. The long session led to higher RPE, RPD and sPDF compared to the short sessions. There was no difference in EES. The short sessions had 3% higher training volume than the long session. There were no differences in perceived readiness to train 24 h after the sessions. Twenty-two participants preferred the long session, while one preferred the short sessions. In conclusion, performing a longer, lower body, resistance training session led to greater perceptions of effort, discomfort and session pleasure than splitting the same program into two shorter sessions among resistance-trained women. However, two shorter sessions led to a greater training volume. (shrink)

Conversation analysis (CA) of children-adult—interaction in various contexts has become an established field of research. However,child therapyhas received limited attention in CA. In child therapy, the general psychotherapeutic practice of achieving empathy faces particular challenges. In relation to this, our contribution sets out three issues for investigation and analysis: the first one is that practices of achieving empathy must be preceded by efforts aiming to establish which kind of individualized conversation works with this child (Midgley,2006). Psychotherapy process researchers in adult (...) therapy (Stiles et al.,2015) have found that therapists “invent” a new therapy for each patient (Norcross and Wampold,2018). The second issue is that it can be difficult for adults to understand the ways in which children express their conflicts and issues. In particular, play activities in therapy, e.g., with dolls, can open up additional scenarios of interaction. The play scenario can be used to disclose unformulated problems masked in everyday and family interactions. The third issue is how to respect the child's higher degree of vulnerability, compared with adult patients. How is it communicated and dealt with in therapy? We present an interaction analysis of a single case study of the first 20 min of a child therapy session with an adopted girl aged 4 years brought to treatment because of “unexplainable rage.” The session was videotaped; parents granted permission. We analyze this session using an applied version of CA. In our analysis, we describe “doing contrariness,” as a conversational practice producing epistemic and affiliative disruptions, while “avoiding doing contrariness” and “remedying contrariness” are strategies for preserving or restoring the affiliative dimension of a relationship (in child therapy). We show how these practices operate in various modes and how they are used by both parties in our case study to variously aid and impedethe achievement of empathy and understanding. (shrink)

ObjectiveTo investigate the instant impact of hemodialysis on the cerebral morphological measurements of patients with end-stage renal disease.Materials and methodsTwenty-five patients undergoing maintenance HD and twenty-eight age-, sex-, and education-matched healthy control were included. The HD group and HC group had 3D high-resolution structural magnetic resonance imaging scans twice and once, respectively. Both groups underwent neuropsychologic tests. The morphological measurements of structural MRI were measured using CAT12 and these measures were compared among three groups. The relationship between morphological measures and (...) clinical parameters and neuropsychological tests were investigated through multiple regression analysis.ResultsCompared to the HC group, the cortical thickness before HD significantly decreased in the bilateral temporal lobe and significantly decreased in the left superior temporal gyrus after HD. The cortical thickness significantly increased in the bilateral temporal lobe, frontal lobe and occipital lobe after HD compared to before HD. The sulcus depth in the bilateral insula, frontal lobe, and parietal lobe after HD significantly increased compared to before HD. No significant differences in sulcus depth between HD and HC were detected. After HD, the cortical thickness of the right parsopercularis was positively correlated with the number connection test-A. Cortical thickness in multiple regions were positively correlated with blood flow velocity and cortical thickness in the left parahippocampal gyrus was negatively correlated with ultrafiltration volume. Patients showed better performance in the digit symbol test and line tracing test after HD compared to before HD, but there were no significant differences in the comparison of neuropsychologic tests between patients and HC.ConclusionThe instant morphological changes were captured during a single hemodialysis in HD patients. There was an association between these instant changes in the brain and clinical parameters and neuropsychologic tests. This work implied the instant impact of a single hemodialysis impact on the brain in HD patients. (shrink)

In sport, perceptual skill training software is intended to assist tactical training in the field. The aim of this field study was to test whether ‘laboratory-based’ pattern recall training would augment tactical skill training performed on the field. Twenty-six soccer players between 14-16 years of age from a single team participated in this study and were divided into three groups. The first received field training on a specific tactical skill plus cognitive training sessions (...) on the pattern recall task. The second performed only the field training while the third group served as a control group and had field training on other topics. The task on the pre-, post- and retention tests was to recall specific soccer patterns displayed on a computer screen. Results showed significant changes between pre- to post-test performance. There was no significant interaction between groups and tests but the effect size was large. From pre- to retention-test, there was a significant difference between tests and an interaction between groups and tests, but no main effect difference between groups. On the basis of significance testing only retention was affected by the additional training, however, descriptive results and effect sizes from pre- to post-test were as expected and suggested there were learning benefits. Together these results indicate that augmented perceptual-cognitive training might be beneficial, but some limitations in our study design (e.g., missing field test, missing placebo group, etc.) need to be improved in future work.

ABSTRACTPrior experiments indicated that reading literary fiction improves mentalising performance relative to reading popular fiction, non-fiction, or not reading. However, the experiments had relatively small sample sizes and hence low statistical power. To address this limitation, the present authors conducted four high-powered replication experiments testing the causal impact of reading literary fiction on mentalising. Relative to the original research, the present experiments used the same literary texts in the reading manipulation; the same mentalising task; and the same kind of participant (...) samples. Moreover, one experiment was pre-registered as a direct replication. In none of the experiments did reading literary fiction have any effect on mentalising relative to control conditions. The results replicate earlier findings that familiarity with fiction is positively correlated with mentalising. Taken together, the present findings call into question whether a single session of rea... (shrink)

ObjectivePreviously Mindfulness-Based Swinging Technique 's immediate efficacy for overcoming psychological concerns has recently received empirical support, yet its longer-term efficacy needed to be evaluated among women with breast cancer. The objective of this study was to assess and report the efficacy of MBST intervention among breast cancer patients for hopelessness, anxiety, depression, self-efficacy, oxygen intensity, and heart rate-beats per minute at an 8-week period.MethodThe State-Trait Anxiety Inventory, The Emotion Thermometer, Hospital Anxiety and Depression Scale, Self-Efficacy for Managing Chronic Disease, and (...) Beck's Hopelessness Scale were used for assessing the intervention's outcome; 149 BC patients were randomly assigned into two groups. The participants in the control group received Cognitive Behavioural Therapy -Cognitive-Disputation for 20 min, and intervention group received MBST intervention. No additional psychological interventions were given between week-1 and week-8.ResultOutcomes of the 8-week post-treatment follow-up exhibited significantly higher improvements in all evaluated-measurements for CG, and some for IG with large effect size in the following: anxiety and depression levels. It increased self-efficacy for managing disease and hopefulness, and saturation levels measured by pulse-meter/oximeter.ConclusionsBoth CBT-CD and MBST have been found to be efficacious interventions to shorten the psychotherapy duration for reducing clinical anxiety and hopelessness as well as increase self-efficacy for BC women. This may have a distinct clinical importance for supporting BC patient's adherence-to-treatment since CBT-CD could be an alternative technique to MBST as a brief intervention. In future studies, the effectiveness of MBST through adapting to virtual reality and other online delivery methods should be examined. (shrink)

In this 6-year, multi-study paper we summarize a new and effective framework of single-session problem-solving developed in an elite sport context at a world leading national institute of sport science and medicine. In Study 1, we used ethnography to observe how single-session problem-solving methods were being considered, explored, introduced and developed within the EIS. In Study 2, we used case-study methods split into two parts. A multiple case-study design was employed in Part one to evaluate how (...) the approach was refined into an effective framework of practice. An individual case-study is then illustrated to detail the framework in-action. Collectively, findings realized a framework of single-session problem-solving for use both inside and outside of elite sport that focused on ways to reframe clients’ problems into more ‘solvable’ descriptions. Guidance for psychologists wishing to integrate these problem-solving techniques into their practice are offered. (shrink)

Individuals with substance use disorders exhibit risk-taking behaviors, potentially leading to negative consequences and difficulty maintaining recovery. Non-invasive brain stimulation techniques such as transcranial direct current stimulation have yielded mixed effects on risk-taking among healthy controls. Given the importance of risk-taking behaviors among substance-using samples, this study aimed to examine the effects of tDCS on risk-taking among a sample of adults using cannabis. Using a double-blind design, 27 cannabis users [M age = 32.48, 41% female] were randomized, receiving one (...) class='Hi'>session of active or sham tDCS over the bilateral dorsolateral prefrontal cortex. Stimulation parameters closely followed prior studies with anodal right dlPFC and cathodal left dlPFC stimulation. Risk-taking—assessed via a modified Cambridge Gambling Task—was measured before and during tDCS. Delay and probability discounting tasks were assessed before and after stimulation. No significant effects of stimulation on risk-taking behavior were found. However, participants chose the less risky option ∼86% of the trials before stimulation which potentially contributed to ceiling effects. These results contradict one prior study showing increased risk-taking among cannabis users following tDCS. There was a significant increase in delay discounting of a $1000 delayed reward during stimulation for the sham group only, but no significant effects for probability discounting. The current study adds to conflicting and inconclusive literature on tDCS and cognition among substance-using samples. In conclusion, results suggest the ineffectiveness of single session dlPFC tDCS using an established stimulation protocol on risk-taking, although ceiling effects at baseline may have also prevented behavior change following tDCS.

While cochlear implantation has benefitted many patients with single-sided deafness (SSD), there is great variability in cochlear implant (CI) outcomes and binaural performance remains poorer than that of normal-hearing (NH) listeners. Differences in sound quality across ears – temporal fine structure (TFS) information with acoustic hearing versus coarse spectro-temporal envelope information with electric hearing – may limit integration of acoustic and electric patterns. Binaural performance may also be limited by inter-aural mismatch between the acoustic input frequency and the place (...) of stimulation in the cochlea. SSD CI patients must learn to accommodate these differences between acoustic and electric stimulation to maximize binaural performance. It is possible that training may increase and/or accelerate accommodation and further improve binaural performance. In this study, we evaluated lateralization training in NH subjects listening to broad simulations of SSD CI signal processing. A 16-channel vocoder was used to simulate the coarse spectro-temporal cues available with electric hearing; the degree of inter-aural mismatch was varied by adjusting the simulated insertion depth (SID) to be 25 mm (SID25), 22 mm (SID22), and 19 mm (SID19) from the base of the cochlea. Lateralization was measured using headphones and head-related transfer functions (HRTFs). Baseline lateralization was measured for unprocessed speech (UN) delivered to the left ear to simulate SSD and for binaural performance with the acoustic ear combined with the 16-channel vocoders (UN+SID25, UN+SID22, and UN+SID19). After completing baseline measurements, subjects completed 6 lateralization training exercises with the UN+SID22 condition, after which performance was re-measured for all baseline conditions. Post-training performance was significantly better than baseline for all conditions (p<0.05 in all cases), with no significant difference in training benefits among conditions. Given that there was no significant difference between the SSD and the SSD CI conditions before or after training, the results suggest that NH listeners were unable to integrate TFS and coarse spectro-temporal cues across ears for lateralization, and that inter-aural mismatch played a secondary role at best. While lateralization training may benefit SSD CI patients, the training may largely improve spectral analysis with the acoustic ear alone, rather than improve integration of acoustic and electric hearing.

The COVID-19 outbreak has simultaneously increased the need for mental health services and decreased their availability. Brief online self-help interventions that can be completed in a single session could be especially helpful in improving access to care during the crisis. However, little is known about the uptake, acceptability, and perceived utility of these interventions outside of clinical trials in which participants are compensated. Here, we describe the development, deployment, acceptability ratings, and pre–post effects of a single-session (...) intervention, the Common Elements Toolbox, adapted for the COVID-19 crisis to support graduate and professional students. Participants, who were not compensated, were randomly assigned to two of three modules: behavioral activation, cognitive restructuring, and gratitude. Over 1 week, 263 individuals began and 189 individuals completed the intervention. Participants reported that the intervention modules were acceptable, helpful, engaging, applicable to their lives, and could help them manage COVID-related challenges. Participants reported pre- to post-program improvements in secondary control and in the perceived negative impact of the COVID-19 crisis on their quality of life. On average, differences in their perceived ability to handle lifestyle changes resulting from the pandemic were positive, but small and at the level of a non-significant trend. Our results highlight the acceptability and utility of an online intervention for supporting individuals through the COVID-19 crisis. (shrink)

In Parkinson’s disease, the fronto-striatal network is involved in motor and cognitive symptoms. Working memory updating training engages this network in healthy populations, as observed by improved cognitive performance and increased striatal BOLD signal. This two-part study aimed to assess the feasibility of WM updating training in PD and measure change in cognition, movement and functional brain response in one individual with PD after WM updating training. A feasibility and single-subject study were performed in which patients (...) with PD completed computerized WM updating training. The outcome measures were the pre-post changes in criterion and transfer cognitive tests; cognitive complaints; psychological health; movement kinematics; and task-related BOLD signal. Participants in the feasibility study showed improvements on the criterion tests at post-test. FL displayed the largest improvements on the criterion tests and smaller improvements on transfer tests. Furthermore, FL reported improved cognitive performance in everyday life. A shorter onset latency and smoother upper-limb goal-directed movements were measured at post-test, as well as increased activation within the striatum and decreased activation throughout the fronto-parietal WM network. This two-part study demonstrated that WM updating training is feasible to complete for PD patients and that change occurred in FL at post-test in the domains of cognition, movement and functional brain response.

Within the Australian university context, research has uncovered increasing levels of psychological distress, in the form of stress, anxiety and depression. Higher rates of psychological distress have been reported in undergraduate students specifically enrolled in creative arts programs. Despite these increasing levels of psychological distress, university students are reluctant to engage with mental health and wellbeing supports. To explore ways to meet the mental health and wellbeing needs of creative arts university students, the Creative Arts and Music Therapy Research Unit (...) at The University of Melbourne commenced a project exploring the benefits and pitfalls of a brief creative arts therapies approach for students attending a campus based wellbeing clinic. This exploratory research study formed the art therapy component of this much broader research endeavor. Creative arts students in this research study were invited to participate in a single session art therapy encounter that involved the visual exploration of the miracle question, asking students to visually depict “what the problem looks like and how it will look when the problem is resolved or you feel like you can cope with it better?” The descriptive findings of this exploratory research study revealed how the combination of art therapy used within a single session framework was able to afford students a novel means to externalize problems, leading students to forming a less internalized view of the self.
