Components of task switching: A closer look at task switching and cue switching

Research using the diffusion model to decompose task-switching effects has contributed to a better understanding of the processes underlying the observed effect in the explicit task cueing paradigm: Previous findings could be reconciled with multiple component models of task switching or with an account on compound-cue retrieval/repetition priming. In the present study, we used two cues for each task in order to decompose task-switch and cue-switch effects. Response time data support previous findings that comparable parts of the switching effect can be attributed to cue-switching and task-switching. A diffusion model analysis of the data confirmed that non-decision time is increased and drift rates are decreased in unpredicted task-switches. Importantly, it was shown that non-decision time was selectively increased in task-switching trials but not in cue-switching trials. Results of the present study specifically support the notion of additional processes in task-switches and can be reconciled with broader multiple component accounts.     

Scham und Familienbeziehungen bei Bulimie

Background

Empirical studies show a relationship between family factors and disturbed eating behavior. Feelings of shame are associated with a higher level of eating disorder symptoms and with family relations perceived as being dysfunctional. Thus shame can be understood as a mediator of the relationship between dysfunctional family relations and eating disorder symptoms.

Material and methods

For 69 female patients, including 55 with bulimia nervosa and 14 with eating disorder not otherwise specified (EDNOS) between 14 and 22 years of age, who participated in a comparative study of psychotherapy outcome, eating disorder symptoms (EDI, EDE-Q), general psychiatric symptoms severity (SCL-90R), level of shame (TESE-KJ) and perceived family relations (FB-A) were measured at the beginning of psychotherapy.

Results

The higher the feeling of shame the more dysfunctional the perceived family relationships were and the more the eating disorders and general symptoms severity were reported. Shame was a partial mediator of the relationship between family functionality and symptoms.

Discussion

Feelings of shame could originate in dysfunctional family relationships but could also evoke more negative perceptions of interpersonal relationships. The direction of causality could not be proven in the correlative design; nevertheless, shame contributes to an understanding of the mechanisms between dysfunctional family relationships and eating disorder symptoms.     

Emotional Mimicry: Why and When We Mimic Emotions

The goal of this review was to provide a brief overview of recent developments in the domain of emotional mimicry research. We argue that emotional signals are intrinsically meaningful within a social relationship, which is crucial for understanding the functionality and boundary conditions of emotional mimicry. On the basis of a review of the literature on facial mimicry of emotion displays, we conclude that the classic matched motor hypothesis does not hold for emotional mimicry. We alternatively propose a contextual view of emotional mimicry, which states that emotional mimicry depends on the social context: we only mimic emotional signals that are interpreted to promote affiliation goals and not necessarily what we see. As a further consequence, we are less likely to mimic strangers and we do not mimic people we do not like nor emotions that signal antagonism.     

From face to face: the contribution of facial mimicry to cognitive and emotional empathy

ABSTRACT

Despite advances in the conceptualisation of facial mimicry, its role in the processing of social information is a matter of debate. In the present study, we investigated the relationship between mimicry and cognitive and emotional empathy. To assess mimicry, facial electromyography was recorded for 70 participants while they completed the Multifaceted Empathy Test, which presents complex context-embedded emotional expressions. As predicted, inter-individual differences in emotional and cognitive empathy were associated with the level of facial mimicry. For positive emotions, the intensity of the mimicry response scaled with the level of state emotional empathy. Mimicry was stronger for the emotional empathy task compared to the cognitive empathy task. The specific empathy condition could be successfully detected from facial muscle activity at the level of single individuals using machine learning techniques. These results support the view that mimicry occurs depending on the social context as a tool to affiliate and it is involved in cognitive as well as emotional empathy.     

Characterizing the Musical Phenotype in Individuals With Williams Syndrome

Williams Syndrome (WS), a neurodevelopmental genetic disorder, is characterized by peaks and valleys in mental function: substantial impairments in cognitive domains such as reasoning, arithmetic ability, and spatial cognition, alongside relatively preserved skills in social domains, face processing, language, and music. We report the results of a comprehensive survey on musical behaviors and background administered to the largest sample of individuals with WS to date (n = 118, mean age = 20.4), and compare the results to those obtained from a control group of typically developing normal individuals (n = 118, mean age = 20.9) and two groups of individuals with other neurodevelopmental genetic disorders, Autism (n = 30, mean age = 18.2) and Down Syndrome (n = 40, mean age = 17.2). Individuals with WS were found to be rated higher in musical accomplishment, engagement, and interest than either of the comparison groups, and equivalent on most measures to the control group. Compared to all other groups including the controls, the WS individuals displayed greater emotional responses to music, manifested interest in music at an earlier age, and spent more hours per week listening to music. In addition, the effects of music listening (whether positive or negative) tended to last longer in the WS group. A factor analysis extracted seven principal components that characterize the musical phenotype in our sample, and discriminant function analysis of those factors was able to successfully predict group membership for the majority of cases. We discuss the neurobiological implications of these findings.     

Association between Inhibitory Control Capacity and Body Weight in Overweight and Obese Children and Adolescents: Dependence on Age and Inhibitory Control Component

It has been assumed that overweight individuals show weak inhibitory control capacity leading to a failure to resist external cues for palatable food and that this deficit underlies the recently reported empirical association between obesity and attention deficit/hyperactivity disorder (ADHD). In childhood and adolescence, empirical research on this issue is scarce. Here, the hypothesis is tested that high body weight is associated with weak inhibitory control performance and that this association is moderated by age.

The sample included 177 overweight and obese children and adolescents (BMI: M = 29.2, SD = 4.33; BMI-SDS: M = 2.45, SD = 0.43) between 8 and 15 years. Inhibitory control was assessed by a Go/No-Go task and an Interference Task. A principal component analysis yielded two components: impulsivity (fast but invalid responses) and inattention (highly variable reaction times).

While controlling for age, gender, and maternal education level, we found that more obese children/adolescents showed more inattention. As indicated by a significant interaction effect, exclusively at younger ages, high impulsivity was associated with high body weight.

The results thus confirm a link between low inhibitory control capacity and high body weight and might point to a developmental period with heightened significance of impulsivity for weight gain.

Emotion and object processing in Parkinson’s disease

The neuropsychological literature on the processing of emotions in Parkinson’s disease (PD) reveals conflicting evidence about the role of the basal ganglia in the recognition of facial emotions. Hence, the present study had two objectives. One was to determine the extent to which the visual processing of emotions and objects differs in PD. The other was to assess the impact of cognitive load on the processing of these types of information. Thirty-one patients with idiopathic PD (IPD) under dopamine replacement therapy (DRT) were compared to 30 control subjects on emotion and object recognition tasks. Recognition of objects was more accurate and faster than recognition of facial expressions of emotion, for both groups of subjects. In a second experiment using an N-back procedure with the same stimuli—a more demanding task with a higher cognitive load—patients with IPD were as accurate as control subjects in detecting the correct sequential presentation of stimuli, but were much slower in their decision responses. This indicates that IPD patients under DRT are not impaired in encoding emotion or object information, but that they have difficulty with the processing demands of the N-back task. Thus, patients with IPD appear to be more sensitive to cognitive load than to type of information, whether facial emotions or objects. In this perspective, one must consider that a deafferented dopaminergic system has problems processing more complex information before one can posit the existence of deficits affecting a specific type of information.     

Are expert athletes ‘expert’ in the cognitive laboratory? A meta‐analytic review of cognition and sport expertise

Recent literature has demonstrated the usefulness of fitness and computer‐based cognitive training as a means to enhance cognition and brain function. However, it is unclear whether the combination of fitness and cognitive training that results from years of extensive sport training also results in superior performance on tests of cognitive processes. In this study we examine, in a quantitative meta‐analysis (k = 20), the relationship between expertise in sports and laboratory‐based measures of cognition. We found that athletes performed better on measures of processing speed and a category of varied attentional paradigms, and athletes from interceptive sport types and males showed the largest effects. Based on our results, more research should be done with higher‐level cognitive tasks, such as tasks of executive function and more varied sub‐domains of visual attention. Furthermore, future studies should incorporate more female athletes and use a diverse range of sport types and levels of expertise. Copyright © 2009 John Wiley & Sons, Ltd.
