Mediation,moderation, and context: Understanding complex relations among cognition,affect, and health behaviour

Objective: Researchers have historically treated cognition and affect as separate constructs in motivating health behaviour. We present a framework and empirical evidence for complex relations between cognition and affect in predicting health behaviour.

Main Outcome, Design and Results: First, affect and cognition can mediate each other’s relation to health behaviour. Second, affect and cognition can moderate the other’s impact. Third, context can change the interplay of affect and cognition. Fourth, affect and cognition may be indelibly fused in some psychological constructs (e.g. worry, anticipated regret and reactance). These four propositions in our framework are not mutually exclusive.

Conclusion: Examination of the types of complex relations described here can benefit theory development, empirical testing of theories and intervention design. Doing so will advance the understanding of mechanisms involved in regulation of health behaviours and the effectiveness of interventions to change health behaviours.     

The relationship between sleep problems and working memory in children born very preterm

In two studies, the relationship between sleep and working memory performance was investigated in children born very preterm (i.e., gestation less than 32 weeks) and the possible mechanisms underlying this relationship. In Study 1, parent-reported measures of snoring, night-time sleep quality, and daytime sleepiness were collected on 89 children born very preterm aged 6 to 7 years. The children completed a verbal working memory task, as well as measures of processing speed and verbal storage capacity. Night-time sleep quality was found to be associated with verbal working memory performance over and above the variance associated with individual differences in processing speed and storage capacity, suggesting that poor sleep may have an impact on the executive component of working memory. Snoring and daytime sleepiness were not found to be associated with working memory performance. Study 2 introduced a direct measure of executive functioning and examined whether sleep problems would differentially impact the executive functioning of children born very preterm relative to children born to term. Parent-reported sleep problems were collected on 43 children born very preterm and 48 children born to term (aged 6 to 9 years). Problematic sleep was found to adversely impact executive functioning in the very preterm group, while no effect of sleep was found in the control group. These findings implicate executive dysfunction as a possible mechanism by which problematic sleep adversely impacts upon cognition in children born very preterm, and suggest that sleep problems can increase the cognitive vulnerability already experienced by many of these children.     

Supervisor Humor and Employee Outcomes: The Role of Social Distance and Affective Trust in Supervisor

Purpose

To examine how social distance and affective trust in supervisor affect the relationships between supervisor humor and the psychological well-being and job performance of subordinates.

Design/Methodology/Approach

A survey was conducted among 322 matched supervisor–subordinate dyads in 14 South Korean organizations. Multi-level analyses were performed to test the research hypotheses, including the moderating effects.

Findings

Self-enhancing humor of supervisors was positively associated with the psychological well-being and job performance of subordinates. Affiliative humor was positively associated with psychological well-being, whereas aggressive humor was negatively associated with psychological well-being. In addition, supervisor humor was indirectly related to the psychological well-being of subordinates via social distance. Moreover, affective trust in supervisor significantly moderated the relationship between supervisor humor and social distance, such that the relationship between affiliative humor and social distance was stronger when affective trust in supervisor was high rather than low.

Implications

These findings are important in developing and refining humor theory on the responses of employees to various types of supervisor humor. Moreover, they provide practical implications for organizations. For example, organizations should note that supervisor humor may not always produce good results, and thus should encourage managers to use constructive humor. Similarly, supervisors should build a high-trust relationship with their subordinates to increase the effectiveness of their constructive humor.

Originality/Value

This study is one of the few studies that has examined the mechanism and boundary conditions of the effects of supervisor humor on employee outcomes.

     

A Developmental Meta-Analysis of Peer Conflict Resolution

A series of meta-analyses examine developmental trends in peer conflict resolution. Peer conflict resolutions are most likely to involve negotiation, with coercion and then disengagement the next most likely strategies. Patterns of conflict resolution differ with age. Coercion is common among children and disengagement is rare. Negotiation is prevalent among adolescents and young adults; the former do not differ in terms of coercion and disengagement, whereas the latter tend to avoid coercion in favor of disengagement. Conflict resolutions also vary as a function of peer relationships, assessment procedures, and reporters. Negotiation prevails in all peer relationships except those with siblings; there is more negotiation among romantic partners than among friends, and more negotiation among friends than among acquaintances. Negotiation is the overwhelming strategy of choice for those presented with hypothetical disputes, but actual conflicts tend to be resolved by coercion. Observers indicate that most conflicts involve coercive resolutions, in contrast to self-reports, which suggest that negotiation prevails. Although conclusions are qualified by the limited number of studies available, follow-up moderator analyses indicate that negotiation increases and coercion declines with age across most peer relationships, assessment procedures, and reporters such that different patterns of conflict resolution during childhood give way to the same relative ordering of strategies during young adulthood.     

Access and equity issues in employment and service provision for NESB immigrants in New Zealand public sector organizations

This article discusses the extent to which New Zealand public sector policies and practices concerning employment and service provision cater for immigrant access and equity needs. The views presented are based on the findings of a study that examined two interrelated areas: (a) the employment and deployment of immigrants with non-English-speaking backgrounds in government organizations; and (b) the degree to which the government services available include, in their delivery systems recognition of the linguistic and cultural requirements of an increasingly diverse population. On the basis of the survey findings, conclusions are reached regarding the need for a coherent and comprehensive policy framework for dealing with immigrant issues.     

Gender stereotypes underlie child custody decisions

Using hypothetical divorce cases we examine the role of gender stereotypes in decisions about child custody. Good mothers received greater custody allocations than did good fathers across a tightly matched pair of vignettes in three culturally distinct samples: Argentina, Brazil, and the United States (Study 1). Two follow-up studies indicated that the warmth dimension of stereotype content partly accounted for the asymmetry in custody awards: The proportion of maternal-primary custody was predicted by the tendency to ascribe warmth-related traits—such as friendliness, generosity, or trustworthiness—to mothers (Study 2) and associate them with female over male nouns (Study 3). We also found that endorsing shared custody mitigated the asymmetry in custody awards documented in our studies. Together, these results highlight the interplay of stereotyped attitudes and egalitarian commitments in the context of judicial decisions about child custody.
