What individuals believe they can and cannot do: explorations of realistic and unrealistic control beliefs

We examined construct validity and implications of scales that assess perceived control over controllable events (realistic control belief) and perceived control over uncontrollable events (unrealistic control belief). We found that people high in unrealistic control belief are less likely to discriminate between controllable and uncontrollable situations and to distort task outcomes so as to make them appear more favorable (more under control). We also found that people high in realistic control belief are more likely to assume responsibility for past mistakes. In additional studies on coping and health risk behavior, higher realistic control belief was related to direct engagement with the stressor and to less risky sexual behavior; higher unrealistic control belief was related to less emotional processing and to more risky sexual behavior. The results demonstrate a need to discriminate between the two types of control beliefs.     

Night and day: are siblings as different in temperament as parents say they are?

Twin studies suggest that parent ratings of temperament exaggerate differences between twins. The present study examined whether such contrast effects also operate for nontwin siblings. The activity level (AL) and shyness of 95 nontwin sibling pairs (ages 3 to 8 years) were assessed via parent ratings and objective measures (actigraph and observer ratings). Siblings showed no resemblance in either parent-rated AL or shyness; however, sibling resemblance for actigraph AL and observer-rated shyness was substantial. Thus, parents do contrast their nontwin siblings when rating these 2 temperament dimensions. Moreover, the importance of sibling differences in temperament to the sibling relationship and differential maternal treatment varied across the different measures of AL and shyness, suggesting that parent perceptions may play a role in these associations.     

When plausibility manipulations work: An examination of their role in the development of false beliefs and memories

In the current study we examined whether prevalence information and imagery encoding influence participants' general plausibility, personal plausibility, belief, and memory ratings for suggested childhood events. Results showed decreases in general and personal plausibility ratings for low prevalence events when encoding instructions were not elaborate; however, instructions to repeatedly imagine suggested events elicited personal plausibility increases for low-prevalence events, evidence that elaborate imagery negated the effect of our prevalence manipulation. We found no evidence of imagination inflation or false memory construction. We discuss critical differences in researchers' manipulations of plausibility and imagery that may influence results of false memory studies in the literature. In future research investigators should focus on the specific nature of encoding instructions when examining the development of false memories.     

Family business: A fertile ground for research on time,teams and positive organizational study

Further reflecting on the study of organizational behaviour (OB) in family business (FB), this rejoinder piece discusses and integrates the points raised in the three thoughtful commentaries and our original article. We start by highlighting the general agreement between us and the commentators on three points: (1) that family firms are theoretically distinct from non-family firms due to significant involvement of kinship ties in the enterprise; (2) there is paucity of research at the interface of OB and FB and (3) there is an abundance of interesting research questions at this interface with the potential to benefit both domains of study. Next, we discuss and elaborate on the research possibilities on time, teams and positive organizational study, suggested by the commentators. An illustrative list of interesting research questions at the OB–FB interface that extend and enrich our agenda for future research is shared. We conclude that not only is FB a promising context for behavioural scholars to investigate, the timing is perfect for such investigations.     

Effects of Age and Control Beliefs on Resource Allocation During Reading Abstract

Past work suggests that a strong sense of control over one's cognitive ability is associated with higher levels of cognitive performance and that control beliefs may be even more important in later life, due to age-related declines in cognitive processes. However, less is known about the effects of control beliefs on encoding strategies, and whether these effects are comparable for younger and older adults. Participants were divided into high- (HC) and low- control (LC) beliefs groups based on their scores on the Personality in Intellectual-Aging Contexts Inventory. Participants then read relatively easy and difficult passages word-by-word on a computer for subsequent recall. The data suggest that among older, but not younger adults, control beliefs are particularly important when reading difficult passages. Findings as they relate to models of self-regulation and to implications for everyday functioning are discussed.     

Cardiovascular and testosterone responses to contested dominance in women

Examined cardiovascular and testosterone responses of dominant and submissive women to an acute stressor involving contested dominance. Twenty (10 dominant, 10 submissive) university students rated their dominance to a predefined reference group, participated in a task that involved debating with a trained technician, and were continuously provided with bogus feedback throughout the task concerning biochemical substances in their blood that purportedly covaried with dominance. Covariance analyses revealed that dominant women were much more reactive to the stressor in several cardiovascular parameters than those classified as submissive. Serum testosterone did not vary as a function of the experimental manipulation, and at each measurement point, dominant and submissive subjects had essentially identical serum levels of this hormone. Interestingly, however, baseline testosterone for the dominant group was related to changes in systolic blood pressure (i.e., gain scores computed as task response minus baseline values).     

Contact and the personal/group discrimination discrepancy in an Inuit community

The personal/group discrimination discrepancy involves disadvantaged group members rating discrimination directed at their group considerably higher than ratings of discrimination aimed at themselves personally as members of that group. This robust phenomenon has been found in samples of women, African Americans, and aboriginal people. In the present study, the authors used a sample of Inuit from a remote Arctic community to confirm the perceived discrepancy. However, ratings for perceived group discrimination were surprisingly low. The authors argue that geographical isolation may have led Inuit to be unaware of the impact of discrimination on their lives. In support of this argument, findings showed that group discrimination ratings were higher for Inuit who did have contact with mainstream Canadian culture. Implications for the traditional contact hypothesis are discussed.     

The relationship between childhood abuse and adult personality disorder symptoms

This study assessed personality disorder symptomatology in a community sample of healthy adults without diagnosable DSM-IV-TR Axis I psychiatric disorders who reported a history of childhood abuse. Twenty-eight subjects with a history of moderate to severe physical, sexual, and/or emotional abuse according to the Childhood Trauma Questionnaire were compared to 33 subjects without an abuse history on symptoms of personality disorders. Subjects in the Abuse group were more likely to report subclinical symptoms of paranoid, narcissistic, borderline, antisocial, obsessive compulsive, passive-aggressive, and depressive personality disorders. These findings link reports of childhood abuse with symptoms of personality disorders in the absence of Axis I psychiatric disorders in a community sample of healthy adults.
