Study of behavioural and neural bases of visuo‐spatial working memory with an fMRI paradigm based on an n‐back task 下载免费PDF全文

The goal of this study was to propose a new functional magnetic resonance imaging (fMRI) paradigm using a language‐free adaptation of a 2‐back working memory task to avoid cultural and educational bias. We additionally provide an index of the validity of the proposed paradigm and test whether the experimental task discriminates the behavioural performances of healthy participants from those of individuals with working memory deficits. Ten healthy participants and nine patients presenting working memory (WM) deficits due to acquired brain injury (ABI) performed the developed task. To inspect whether the paradigm activates brain areas typically involved in visual working memory (VWM), brain activation of the healthy participants was assessed with fMRIs. To examine the task's capacity to discriminate behavioural data, performances of the healthy participants in the task were compared with those of ABI patients. Data were analysed with GLM‐based random effects procedures and t‐tests. We found an increase of the BOLD signal in the specialized areas of VWM. Concerning behavioural performances, healthy participants showed the predicted pattern of more hits, less omissions and a tendency for fewer false alarms, more self‐corrected responses, and faster reaction times, when compared with subjects presenting WM impairments. The results suggest that this task activates brain areas involved in VWM and discriminates behavioural performances of clinical and non‐clinical groups. It can thus be used as a research methodology for behavioural and neuroimaging studies of VWM in block‐design paradigms. 相似文献

Personality dimension extraversion describes individual differences in social behaviour and socio‐emotional functioning. The intrinsic functional connectivity patterns of the brain are reportedly associated with extraversion. However, whether or not extraversion is associated with functional hubs warrants clarification. Functional hubs are involved in the rapid integration of neural processing, and their dysfunction contributes to the development of neuropsychiatric disorders. In this study, we employed the functional connectivity density (FCD) method for the first time to distinguish the energy‐efficient hubs associated with extraversion. The resting‐state functional magnetic resonance imaging data of 71 healthy subjects were used in the analysis. Short‐range FCD was positively correlated with extraversion in the left cuneus, revealing a link between the local functional activity of this region and extraversion in risk‐taking. Long‐range FCD was negatively correlated with extraversion in the right superior frontal gyrus and the inferior frontal gyrus. Seed‐based resting‐state functional connectivity (RSFC) analyses revealed that a decreased long‐range FCD in individuals with high extraversion scores showed a low long‐range functional connectivity pattern between the medial and dorsolateral prefrontal cortex, middle temporal gyrus, and anterior cingulate cortex. This result suggests that decreased RSFC patterns are responsible for self‐esteem, self‐evaluation, and inhibitory behaviour system that account for the modulation and shaping of extraversion. Overall, our results emphasize specific brain hubs, and reveal long‐range functional connections in relation to extraversion, thereby providing a neurobiological basis of extraversion. 相似文献

Considering the impostor phenomenon (IP) as an important psychological construct in the context of career development requires a theoretical grounding. Using the career construction model of adaptation as a guiding framework, we investigated how the IP is related to adaptive readiness (represented by core self-evaluations), career adaptability resources, and adapting responses, namely, career planning, career decision-making difficulties, career exploration, and occupational self-efficacy. We used parallel multiple mediation modeling to investigate specific indirect effects through concern, control, curiosity, confidence, and the IP. We conducted an online study with 289 university students. Results indicated a positive effect of core self-evaluations on career planning, career exploration, and occupational self-efficacy and a negative effect on career decision-making difficulties through adaptability resources. The IP emerged as a “maladaptability” resource: That is, it might be a hindrance to adaptive coping and behavior and consequently promote maladaptive coping and behavior by decreasing career planning and occupational self-efficacy and increasing career decision-making difficulties. Supplementary negative effects of the IP on adaptability resources are discussed. 相似文献

Further analysis of subtypes of automatically reinforced SIB: A replication and quantitative analysis of published datasets 下载免费PDF全文

Hagopian, Rooker, and Zarcone (2015) evaluated a model for subtyping automatically reinforced self‐injurious behavior (SIB) based on its sensitivity to changes in functional analysis conditions and the presence of self‐restraint. The current study tested the generality of the model by applying it to all datasets of automatically reinforced SIB published from 1982 to 2015. We identified 49 datasets that included sufficient data to permit subtyping. Similar to the original study, Subtype‐1 SIB was generally amenable to treatment using reinforcement alone, whereas Subtype‐2 SIB was not. Conclusions could not be drawn about Subtype‐3 SIB due to the small number of datasets. Nevertheless, the findings support the generality of the model and suggest that sensitivity of SIB to disruption by alternative reinforcement is an important dimension of automatically reinforced SIB. Findings also suggest that automatically reinforced SIB should no longer be considered a single category and that additional research is needed to better understand and treat Subtype‐2 SIB. 相似文献

In the Italian academic system, a student can enroll for an exam immediately after the end of the teaching period or can postpone it; in this second case the exam result is missing. We propose an approach for the evaluation of a student performance throughout the course of study, accounting also for nonattempted exams. The approach is based on an item response theory model that includes two discrete latent variables representing student performance and priority in selecting the exams to take. We explicitly account for nonignorable missing observations as the indicators of attempted exams also contribute to measure the performance (within-item multidimensionality). The model also allows for individual covariates in its structural part. 相似文献

Over several decades, appraisal theory has emerged as a prominent theoretical framework explaining the elicitation and differentiation of emotions, and has stimulated a great deal of theorising and empirical research. Despite the large amount of research in this area, there are many aspects of appraisal theory and research that remain unclear or problematic. In this review, we identify a common assumption of many appraisal theories—the fixed appraisal set—and argue that this assumption, combined with a lack of explicit theorising about the predicted relationship between appraisals and emotions, leads to a lack of clarity in both appraisal models and the empirical testing of those models. We recommend that appraisal theorists move in a direction already taken by a small number of theorists, and adopt the starting assumption of a variable appraisal set. We further suggest that theories of concepts and categorisation may inform theorising about appraisal–emotion relationships. 相似文献

Individuals with Autism Spectrum Disorder (ASD) often present with comorbid Obsessive Compulsive Behaviors (OCBs), but little research exists on effective intervention for OCBs. Using a single-case experimental design, this study highlights the efficacy of a Group Functional Behavior-based Cognitive-Behavior Therapy (Fb-CBT) to reduce OCBs in an 11-year-old youth with ASD. Tailored to the individual needs of this youth, Fb-CBT included traditional CBT components (e.g., psychoeducation, cognitive-behavioral skills training, and exposure and response prevention) coupled with functional behavior assessment and intervention. Time-series parent report data and standardized measures showed clinically significant decreases in OCBs, an increase in psychosocial functioning, and high consumer satisfaction. 相似文献

Dual‐system models propose that cognitive processing can occur either intuitively or deliberately. Unlike deliberate decision strategies, intuitive ones are assumed to have an emotional component attached to the decision process. We tested if intuitive decisions are indeed accompanied by an emotional response while deliberate decisions are not. Specifically, we conducted a psychophysiological study in which participants were instructed to decide either intuitively or deliberately if three simultaneously presented words were semantically coherent or incoherent (triad task). The degree of emotionality of these two decision strategies (intuitive vs. deliberate) was compared using changes in electrodermal activity (EDA) and the reaction time (RT) effect of an affective priming paradigm as primary measurements. Based on a valence‐arousal model, our results revealed that intuitive and deliberate judgments do not differ as to their emotional valence but that they do differ in emotional arousal. Most notably, sympathetic activation during intuitive judgments was significantly lower compared to sympathetic activation during deliberate judgments. Our results reflect that a relaxed state of mind—manifested in low sympathetic activity—could underlie the holistic processing that is assumed to facilitate the proliferation of semantic associations during coherence judgments. This suggests that coherence judgments made under an (instructed) intuitive decision mode have a specific psychophysiological signature and that arousal is the differentiating component between intuitive and deliberate decision strategies. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd. 相似文献
