Getting less than their fair share: Maltreated youth are hyper‐cooperative yet vulnerable to exploitation in a public goods game

Human cooperative behavior has long been thought to decline under adversity. However, studies have primarily examined perceived patterns of cooperation, with little eye to actual cooperative behavior embedded within social interaction. Game‐theoretical paradigms can help close this gap by unpacking subtle differences in how cooperation unfolds during initial encounters. This study is the first to use a child‐appropriate, virtual, public goods game to study actual cooperative behavior in 329 participants aged 9–16 years with histories of maltreatment (n = 99) and no maltreatment (n = 230) while controlling for psychiatric symptoms. Unlike work on perceived patterns of cooperation, we found that maltreated participants actually contribute more resources to a public good during peer interaction than their nonmaltreated counterparts. This effect was robust when controlling for psychiatric symptoms and peer problems as well as demographic variables. We conclude that maltreatment may engender a hyper‐cooperative strategy to minimize the odds of hostility and preserve positive interaction during initial encounters. This, however, comes at the cost of potential exploitation by others.     

Increasing access to low‐intensity interventions for childhood anxiety: A pilot study of a guided self‐help program for Scandinavian parents

Cognitive Behavior Therapy (CBT) is an effective treatment for child anxiety. However, access to treatment is limited. It has been suggested that low‐intensity formats of parent‐delivered CBT may improve access to treatment. Our aim was to develop and pilot‐test the acceptability and effect of a low‐intensity therapist‐guided parent‐delivered group program for anxious children (age 7–12 years) adjusted to the Scandinavian culture. The program required 1.5 hours of therapist‐time per family. Mothers, fathers and children reported on revised child anxiety and depression scale (RCADS) at referral, pre‐ and post‐treatment. Mothers and fathers also gave a qualitative account of their experiences. Thirty‐one families were enrolled and only one family dropped out. Mean age of the children was 9 years. Intent‐to‐treat analyses revealed significant reductions in anxiety and depressive symptoms from pre‐ to post‐treatment for all informants. Large effect sizes were found for child anxiety symptoms as reported by mothers and fathers, and for child depressive symptoms as reported by mothers. Medium to large effect sizes was found for the self‐reported anxiety symptoms by the children, and for depressive symptoms reported by both children and fathers. More than 93% of the parents would recommend the program. Results suggest that our program may provide a new approach to improve access to treatment for anxious children in Scandinavia; however, further research must be conducted before firm conclusions can be drawn.     

Probabilistic dynamic belief revision

We investigate the discrete (finite) case of the Popper–Renyi theory of conditional probability, introducing discrete conditional probabilistic models for knowledge and conditional belief, and comparing them with the more standard plausibility models. We also consider a related notion, that of safe belief, which is a weak (non-negatively introspective) type of “knowledge”. We develop a probabilistic version of this concept (“degree of safety”) and we analyze its role in games. We completely axiomatize the logic of conditional belief, knowledge and safe belief over conditional probabilistic models. We develop a theory of probabilistic dynamic belief revision, introducing probabilistic “action models” and proposing a notion of probabilistic update product, that comes together with appropriate reduction laws.     

An ERP investigation on the temporal dynamics of emotional prosody and emotional semantics in pseudo- and lexical-sentence context

Previous evidence supports differential event-related brain potential (ERP) responses for emotional prosodic processing and integrative emotional prosodic/semantic processing. While latter process elicits a negativity similar to the well-known N400 component, transitions in emotional prosodic processing elicit a positivity. To further substantiate this evidence, the current investigation utilized lexical-sentences and sentences without lexical content (pseudo-sentences) spoken in six basic emotions by a female and a male speaker. Results indicate that emotional prosodic expectancy violations elicit a right-lateralized positive-going ERP component independent of basic emotional prosodies and speaker voice. In addition, expectancy violations of integrative emotional prosody/semantics elicit a negativity with a whole-head distribution. The current results nicely complement previous evidence, and extend the results by showing the respective effects for a wider range of emotional prosodies independent of lexical content and speaker voice.     

Sexualdelinquenz bei Schizophrenie

Studies suggest a complex relationship between schizophrenia and sexually offensive behaviour. This study aimed to preserve first findings of sex offence features and behaviours exhibited by psychotic men in Germany. Furthermore a typology of the schizophrenic offender group was developed. A comparative trial design was used to differentiate the psychotic and non psychotic offender group. A checklist was developed and applied to the records of 64 male restricted hospital order in-patients in Berlin with an index conviction for a contact sex offence against a woman. Social isolation, antisocial behaviour, psychosexual variables and adverse childhood experiences are found for schizophrenic and sexual offenders in general. Different sexual offensive behaviours appeared in the schizophrenic subgroups. Negative symptoms of schizophrenia as well as antisocial traits had a great impact on schizophrenic sexual offending. A heterogeneous group of psychotic offenders can be supposed.     

Excel: An intensive and structured program of advising and academic support to assist minority freshmen to succeed at a large state university

It is a consistent observation that minority students graduate at much lower rates than majority students at our large state colleges and universities. The Excel program was designed to assist ethnic minority students adjust to the demands of university life and succeed both academically and personally. The program has three major components: a two semester two credit core seminar, weekly instructional support groups, and peer led tutorial/discussion groups. The results of the first two years of the program were evaluated in a number of studies comparing the performance of the Excel students to other minority and majority freshmen at the university. In all comparisons the Excel students were found to have performed significantly better than other minority groups and equal to or better than majority students. The results are discussed in terms of the variables that appear to affect minority student success at large universities.     

Cross-cultural validity of the masculine and feminine gender role stress scales

The objective was to examine the usefulness of Dutch versions of the Masculine Gender Role Stress (MGRS; Eisler & Skidmore, 1987) Scale and the Feminine Gender Role Stress (Gillespie & Eisler, 1992) Scale in The Netherlands. Undergraduate students (N = 2,239) completed both gender role stress scales. A subgroup (n = 508) also completed questionnaires about masculinity-femininity and daily hassles. With regard to both gender role stress scales, results of confirmatory factor analyses supported the original 5-factor structures and revealed no cross-sex differences on the factor models. Reliability and homogeneity indexes were all well within acceptable to satisfactory limits. Further evidence of construct validity was found in (a) medium to large correlations with daily hassles, (b) sex differences on the FGRS scale, and (c) small to medium correlations with masculinity-femininity. The major discrepancy with previous studies was that for Dutch female and male students, the MGRS scale was not sex specific. Taken together, this study sustained the utility of both gender role stress scales for use in The Netherlands.     

The benefits of frequent positive affect: does happiness lead to success?

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors suggest a conceptual model to account for these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive affect engenders success. Three classes of evidence--crosssectional, longitudinal, and experimental--are documented to test their model. Relevant studies are described and their effect sizes combined meta-analytically. The results reveal that happiness is associated with and precedes numerous successful outcomes, as well as behaviors paralleling success. Furthermore, the evidence suggests that positive affect--the hallmark of well-being--may be the cause of many of the desirable characteristics, resources, and successes correlated with happiness. Limitations, empirical issues, and important future research questions are discussed.     

Patterns and predictors of change in energy and mood around a vacation from the workplace: Distinguishing the effects of supplemental work activity and work-related perseverative cognition

This study contributes to the vacation literature by exploring predictors of change in school teachers' negative affective states around a 2-week (Christmas) vacation. Drawing from a combination of self-regulatory and effort-recovery theoretical principles, we hypothesized that supplemental work activity during the vacation might have some positive consequences for mood state, while simultaneously impairing the ability to recover from work-related exhaustion. Ninety teachers completed measures across eight consecutive weeks, spanning the period before, during and after vacation (710 observations in total). Teachers' weekly levels of emotional exhaustion, anxious mood and depressed mood decreased significantly from before to during the vacation. Following the vacation, anxious mood showed the most rapid rate of increase, returning to its prevacation level within 2 weeks of work resumption. Exhaustion and depressed mood re-emerged more gradually across 4 consecutive weeks following the vacation. Supplemental work activity during the vacation was associated with weaker recovery from exhaustion, but did not exhibit a detrimental relationship with change in anxious or depressed mood. Of note, supplemental working during the vacation was associated with a less pronounced re-emergence of anxious mood after the vacation. Work-related perseverative cognition (worry and rumination) during the vacation impeded energy restoration and mood repair and was related to faster fade out of beneficial vacation effects. These findings demonstrate the utility of examining discrete energy and mood states in respite research, reveal the mixed functions of engaging in supplemental work activity during vacations and highlight the harmful impact of perseverative cognition on the recovery from work process.
