Differential effects of social and non‐social reward on response inhibition in children and adolescents

An important issue in the field of clinical and developmental psychopathology is whether cognitive control processes, such as response inhibition, can be specifically enhanced by motivation. To determine whether non‐social (i.e. monetary) and social (i.e. positive facial expressions) rewards are able to differentially improve response inhibition accuracy in typically developing children and adolescents, an ‘incentive’ go/no‐go task was applied with reward contingencies for successful inhibition. In addition, the impact of children's personality traits (such as reward seeking and empathy) on monetary and social reward responsiveness was assessed in 65 boys, ages 8 to 12 years. All subjects were tested twice: At baseline, inhibitory control was assessed without reward, and then subjects were pseudorandomly assigned to one of four experimental conditions, including (1) social reward only, (2) monetary reward only, (3) mixed social and monetary reward, or (4) a retest condition without reward. Both social and non‐social reward significantly improved task performance, although larger effects were observed for monetary reward. The higher the children scored on reward seeking scales, the larger was their improvement in response inhibition, but only if monetary reward was used. In addition, there was a tendency for an association between empathic skills and benefits from social reward. These data suggest that social incentives do not have an equally strong reinforcing value as compared to financial incentives. However, different personality traits seem to determine to what extent a child profits from different types of reward. Clinical implications regarding probable hyposensitivity to social reward in subjects with autism and dysregulated reward‐seeking behaviour in children with attention‐deficit/hyperactivity disorder (ADHD) are discussed.     

Participation restrictions at work indicate participation restrictions in other domains of life

Health problems are often associated with activity limitations and participation restrictions, as defined in the International Classification of Functioning, Disability and Health (ICF). This often affects the workplace in the form of sick leave or a reduction in productivity. The question is, "to what extent are participation restrictions at work related to participation restrictions in other domains of life?" A total of 382 primary health care patients (aged 18-65) were asked to provide information on their employment status, perceived health-related workplace problems and sick leave status. Health-dependent participation restrictions across different domains of life were assessed using the Index for Measuring Participation Restrictions (IMET) self rating questionnaire. Currently unemployed patients reported significantly higher degrees of participation restrictions across all domains of life than the employed participants. Employed patients with workplace problems scored higher than patients without workplace problems. The domain of work encompassed the highest level of impairment, while the lowest was observed in personal relationships. Workplace problems occur frequently for primary health care patients. They coincide with participation restrictions in other domains of life. For patients who complain about their capacity to work, diagnosis and treatment must not only focus on the work domain, but also enquire into and consider participation restrictions in other domains of life.     

A Great Many Things to Do and Not a Minute to Spare: Can Feedback From Supervisors Moderate the Relationship Between Skill Variety,Time Pressure,and Employees' Innovative Behavior?

Workplace changes necessitate employees' innovative behavior. Developing and implementing new ideas can be enhanced by focusing on situational characteristics and adjusting them to improve employees' working conditions. To date, mostly interactions between situational and personal characteristics on innovative behavior have been researched. This study focused explicitly on the interaction between 3 situational characteristics: time pressure, skill variety, and feedback from supervisors. A questionnaire study was administered to 81 employees (age range 40–64 years) from different organizations. Results indicated direct positive correlations between time pressure and skill variety with idea generation and implementation. Feedback from supervisors moderated the positive relationships while controlling for effects of creative thinking abilities. Implications are explored.     

On the action of social groups

This paper deals with the question of whether and when it is appropriate or inappropriate to say that a social group performs an action. After some remarks on the concept of action three kinds of groups are distinguished, i.e. assemblies, institutions, and classes. It is found that in the first two of these cases predication of action is possible: an assembly can act in that all its members act, or some of them do who are interchangeable with any others; and an institution can act because it has a structure and some individuals can act on its behalf. A class, however, cannot be said to act, for its concept may be freely formed, its members cannot be assembled, and it has no organs through which actions could be performed.     

Sex differences in neural efficiency: Are they due to the stereotype threat effect?

The neural efficiency hypothesis postulates a more efficient use of brain resources in more intelligent people as compared to less intelligent ones. However, this relationship was found to be moderated by sex and task content. While the phenomenon of neural efficiency was previously supported for men when performing visuo-spatial tasks it occurred for women only when performing verbal tasks. One possible explanation for this finding could be provided by the well-studied phenomenon called stereotype threat. Stereotype threat arises when a negative stereotype of one’s own group is made salient and can result in behavior that confirms the stereotype. Overall, 32 boys and 31 girls of varying intellectual ability were tested with a mental rotation task, either under a stereotype exposure or a no-stereotype exposure condition while measuring their EEG. The behavioral results show that an activated negative stereotype not necessarily hampers the performance of girls. Physiologically, a confirmation of the neural efficiency phenomenon was only obtained for boys working under a no-stereotype exposure condition. This result pattern replicates previous findings without threat and thus suggests that sex differences in neural efficiency during visuo-spatial tasks may not be due to the stereotype threat effect.     

The Relationship Between Sluggish Cognitive Tempo,Subtypes of Attention-Deficit/Hyperactivity Disorder,and Anxiety Disorders

The objective of the present study was to examine the relationship between sluggish cognitive tempo (SCT), subtypes of attention-deficit/hyperactivity disorder (ADHD), and anxiety disorders (AnxDs). One hundred and forty-one children (90 males, 51 females) aged 7–13 years were assigned to four groups, i.e., referred children with comorbid AnxDs and ADHD (n = 25), ADHD (n = 39), AnxDs (n = 41), and nonreferred controls (n = 36). Furthermore we explored the association between SCT and several neurocognitive measures (reaction time, verbal memory, and spatial memory). Diagnoses were established using Kiddie-SADS P/L. SCT was assessed using a 17-item mother-reported questionnaire. SCT correlated significantly with inattentiveness, regardless of the subtype of ADHD. Furthermore, we found significant differences in the levels of SCT among the four groups, with the highest SCT scores observed in the comorbid group. SCT correlated with variability in spatial memory; in contrast, there was no correlation between SCT and reaction time.     

Processes underlying congruent and incongruent facial reactions to emotional facial expressions

The present electromyographic study is a first step toward shedding light on the involvement of affective processes in congruent and incongruent facial reactions to facial expressions. Further, empathy was investigated as a potential mediator underlying the modulation of facial reactions to emotional faces in a competitive, a cooperative, and a neutral setting. Results revealed less congruent reactions to happy expressions and even incongruent reactions to sad and angry expressions in the competition condition, whereas virtually no differences between the neutral and the cooperation condition occurred. Effects on congruent reactions were found to be mediated by cognitive empathy, indicating that the state of empathy plays an important role in the situational modulation of congruent reactions. Further, incongruent reactions to sad and angry faces in a competition setting were mediated by the emotional reaction of joy, supporting the assumption that incongruent facial reactions are mainly based on affective processes. Additionally, strategic processes (specifically, the goal to create and maintain a smooth, harmonious interaction) were found to influence facial reactions while being in a cooperative mindset. Now, further studies are needed to test for the generalizability of these effects.     

Die Zukunft gestalten im Angesicht der Vergangenheit

We report on the 4th Nazareth Conference with Jewish and German participants, most of whom are psychoanalysts. As Herman Beland has observed, these Conferences are intended to be “something like a self-experiment by Germans and Israelis to become, in the presence of the other group, aware of the unconscious identity of both people after the Holocaust.” There is still a widespread inability to mourn for the consequences of the terrible events in the years between 1933 and 1945 and deal satisfactorily with their effects. None of the groups, neither the German, nor the Israeli / Jewish, can do their own inner work without the other. For this reason, the method chosen as appropriate was the Tavistock-style “group relations conference”. This approach was developed by the Institute of Human Relations in London and does not focus on the individual’s behaviour but uses large and small groups to investigate group processes in the here and now. -The present work describes, among other things, the unexpectedly strong resistance towards changes of the conscious and unconscious inner images both of one’s own group and of the other. This process led to a feeling of hopelessness and paralysis within the German group that, due to the presence of the Jewish group, we could not avoid. For the Germans, it was hard to bear and observe the mutually shared history. Jewish participants were not able to accept their own German–Austrian childhood memories as a part of their own identity and connect them to the Germans. Each participant across the groups experienced the fantasy of destruction and the unfruitful effects of division. We had to feel how much the fate of the Germans and the Jews were interlocked to understand the participants’ tensions and efforts for opening new pathways.
