“Man's best friend:” How the presence of a dog reduces mental distress after social exclusion

A substantial amount of research shows that social exclusion is a threat to mental health. In the research reported here, we tested the hypothesis that the presence of a companion animal can serve as a buffer against these adverse effects. In a controlled laboratory experiment, we found that only socially excluded participants who did not work in the presence of a dog reported lower mental well-being compared with socially excluded participants who performed in the presence of a dog and participants who were not socially excluded. The theoretical and practical implications of these findings are discussed.     

Multi-wave Prospective Examination of the Stress-Reactivity Extension of Response Styles Theory of Depression in High-Risk Children and Early Adolescents

The current study tested the stress-reactivity extension of response styles theory of depression (Nolen-Hoeksema Journal of Abnormal Psychology 100:569–582, 1991) in a sample of high-risk children and early adolescents from a vulnerability-stress perspective using a multi-wave longitudinal design. In addition, we examined whether obtained results varied as a function of either age or sex. During an initial assessment, 56 high-risk children (offspring of depressed parents; ages 7–14) completed measures assessing rumination and depressive symptoms. Children were subsequently given a handheld personal computer which signalled them to complete measures assessing depressive symptoms and negative events at six randomly selected times over an 8-week follow-up interval. In line with hypotheses, higher levels of rumination were associated with prospective elevations in depressive symptoms following the occurrence of negative events. Sex, but not age, moderated this association. Rumination was more strongly associated with elevations in depressive symptoms following the occurrence of negative events in girls than in boys.     

Day-to-day variability in nap duration predicts medical morbidity in older adults

Objective: The objectives for the present study were to (a) examine within-person variability of nap duration and (b) assess how variability in nap duration is related to the number of health conditions in a sample of older adults. For highly variable behaviors such as sleep, it is important to consider fluctuations within the person instead of solely comparing averages of behaviors across persons. Method: Data were drawn from a previous study examining sleep in 103 community-dwelling older adults. Subjective estimates of napping behavior were obtained from sleep diaries and objective estimates of napping behavior were obtained using actigraphy. Both measures were collected for 14 consecutive days. The sampled data were aggregated in terms of (a) average daily time spent napping and (b) average within-person fluctuations in daily nap duration. The health measure consisted of the number of self-reported health conditions. Results: Both the objective and subjective measures revealed that there was considerable day-to-day fluctuation in nap duration and that variability in nap duration, not mean duration, uniquely predicted the number of health conditions, b = .03, b* = .26, t(100) = 2.71, p = .01. Conclusions: Duration of napping in older adults is a highly variable behavior, fluctuating as much within- as between-persons. Furthermore, variability in nap duration from day to day is predictive of greater medical morbidity, suggesting that clinicians should assess for inconsistencies in nap behavior in addition to duration, frequency, and timing.

Color categories and color appearance

We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary were perceptually exaggerated. This task did not require overt judgments of the perceived colors, and the tendency to group showed only a weak and inconsistent categorical bias. In a second case, we analyzed results from two prior studies of hue scaling of chromatic stimuli (De Valois, De Valois, Switkes, & Mahon, 1997; Malkoc, Kay, & Webster, 2005), to test whether color appearance changed more rapidly around the blue-green boundary. In this task observers directly judge the perceived color of the stimuli and these judgments tended to show much stronger categorical effects. The differences between these tasks could arise either because different signals mediate color grouping and color appearance, or because linguistic categories might differentially intrude on the response to color and/or on the perception of color. Our results suggest that the interaction between language and color processing may be highly dependent on the specific task and cognitive demands and strategies of the observer, and also highlight pronounced individual differences in the tendency to exhibit categorical responses.     

Decision making in children and adolescents: impaired Iowa Gambling Task performance in early adolescence

Disadvantageous decision making is cited as one of the premier problems in childhood development, underlying risky behavior and causing adolescents to make poor choices that could prove detrimental later in life. However, there are relatively few studies looking at the development of decision making in children and adolescents, and fewer still comparing it with the performance trajectories of more typically developing cognitive functions. In the current study, we measured the affective decision-making abilities of children and adolescents 8- to 17-years-old using the Iowa Gambling Task (IGT; Bechara, 2007) in conjunction with a battery of established cognitive neuropsychological assessments. In contrast to the typical linear development of executive functions, affective decision-making abilities progressed in a J-shaped curve. Younger, more developmentally naive children performed better on the IGT than older, early-adolescent individuals, with performance becoming advantageous again toward the end of the teenage years. This trajectory is thought to coincide with asymmetric neural development in early adolescents, with relatively overactive striatal regions creating impulsive reward-driven responses that may go unchecked by the slower developing inhibitive frontal cortex. This trajectory is in stark contrast with the linear development of memory, speed of processing, and other cognitive abilities over the ages.     

System justification and the defense of committed relationship ideology

A consequential ideology in Western society is the uncontested belief that a committed relationship is the most important adult relationship and that almost all people want to marry or seriously couple (DePaulo & Morris, 2005). In the present article, we investigated the extent to which the system justification motive may contribute to the adoption of this ideology. In Studies 1 and 2, we examined whether a heightened motive to maintain the status quo would increase defense of committed relationship values. In Study 3, we examined the reverse association, that is, whether a threat to committed relationship ideology would also affect sociopolitical system endorsement. As past research has found that the justification of political systems depends upon how much these systems are perceived as controlling, in Study 4 we tested whether the defense of the system of committed relationships would also increase when framed as controlling. Results from Studies 1-4 were consistent with our hypotheses, but only for men. In Study 5, using cross-cultural data, we sought to replicate these findings correlationally and probe for a cause of the gender effect. Results from more than 33,000 respondents indicated a relationship (for men) between defense of the sociopolitical system and defense of marriage in countries where the traditional advantages of men over women were most threatened. In Studies 6 and 7, we investigated when this gender difference disappears. Results revealed that when we measured (Study 6) or manipulated (Study 7) personal relationship identity rather than relationship ideology, effects also emerge for women.     

Seeing isn't believing: the effect of intergroup exposure on children's essentialist beliefs about ethnic categories

Adults and children seem to essentialize certain social categories. Three studies investigated whether, and how, exposure to ethnic diversity affects this bias. Participants were 516 kindergarten, 2nd grade, and 6th grade Israeli Jewish and Arab children attending regular (mono-cultural) or integrated schools. Study 1 revealed that exposure increased the salience of ethnicity, especially for Jewish children. Study 2 showed no differences among groups at kindergarten regarding the relevance of recalling a story character's ethnicity, but by 2nd grade, Jewish children attending integrated schools were the most likely to mention such information. Finally, Study 3 revealed that while all kindergarteners started off at a similar level of essentialism towards ethnicity, exposure affected Arab, but especially Jewish, children's essentialist beliefs. Moreover, there were negative correlations between the salience of and essentialism towards ethnicity. Thus, interethnic exposure alleviated children's essentialist bias towards ethnicity and did so via making children aware of, rather than blind to, ethnic categories.     

The development of the Social Bullying Involvement Scales

This study reports findings of a newly developed measure of social bullying based on Underwood's [2003] framework of social aggression. The Social Bullying Involvement Scales (SBIS) consist of four scales measuring the extent to which children experience social victimization, engage in social bullying, witness social bullying, and intervene in social bullying. The sample consisted of 636 participants (311 females and 325 males, age range 11-16 years; 71% White). Confirmatory factor analysis supported a revised version of Underwood's framework for each of the four participant role scales. Internal consistencies for each scale ranged from .93 to .97. Results revealed that social victimization was related to an increase in anxiety, depressive, and externalizing behaviors. Social bullying was associated with an increase in general externalizing behaviors only. Social witnessing was moderately correlated with depression scores. Intervening in social bullying was not linked with psychological maladjustment or externalizing behaviors. The SBIS provides a comprehensive measure of social victimization, social bullying, social witnessing, and social intervening.     

Initial validation of a measure of self-efficacy in romantic relationships

This study examines the psychometric properties of a self-report measure of self-efficacy in romantic relationships (SERR). Analyses (with 775 undergraduates) indicated a coherent factor structure representing broad beliefs about task demands in romantic relationships and abilities to meet such demands. SERR scores predict relationship anxiety and expectations of relationship success when demographic characteristics, current romantic relationship status, general self-efficacy, and social self-efficacy are considered. The SERR assesses broad feelings of relationship self-efficacy, independent of specific relationships or partners, important for understanding individual-level relationship expectations, behaviors, and interventions.
