Well-being and Need for Support of Adolescents with a Chronically Ill Family Member

This study investigates whether there are differences in the well-being, need for help and use of support services between adolescents with and without a chronically ill or disabled family member. It also examines the role played by the type of illness, the relationship to the family member and the nature and intensity of the help provided by the adolescent. A Dutch sample of 1581 adolescents (average age 14.6?years) completed a questionnaire in 2010 about mental health problems, pro-social behavior, need for and use of support and the illness of family members and any care tasks performed by the respondent. Young people with a sick family member had more mental health problems than their counterparts without a chronically ill family member. They also reported a greater need for and use of help and support. Performing domestic tasks was found to be a predictor for overall mental health problems. The intensity of the help given was related to the need for help by the adolescent. It is concluded that growing up with a chronically ill family member and spending a lot time performing (domestic) tasks are risk factors for adolescent mental health problems and adolescents’ need for help. Special attention is warranted for those who need support but who do not translate that need into reality by seeking help.     

Believe What I Believe: Correspondence Between the Beliefs of Young Adults and the Perceived Beliefs of Their Caregivers

Little research has examined the mechanisms through which adult children adopt beliefs across a range of contexts. Through an online survey, the authors examined belief transmission via the correspondence between beliefs of 837 young adults and the perceived ideological beliefs of their caregivers as a function of attachment, parental behavior, and religious beliefs in four domains: moral, political, religious, and lifestyle. The strongest predictor of belief transmission across domains was the geographic location in which the participants were sampled, with individuals currently residing in the Southern region of the United States indicating greater belief transmission compared with those residing in the Midwestern region of the United States. Women also exhibited greater belief transmission compared with men. Controlling for these predictors, we also found that insecurity was negatively related to belief transmission, whereas authority, autonomy, and religious attachment were positively related to belief transmission in some contexts. Taken together, these results suggest that the relationships that young adults remembered having had with their primary caregivers were associated with the transmission of their caregivers’ beliefs.     

Do chimpanzees learn reputation by observation? Evidence from direct and indirect experience with generous and selfish strangers

Can chimpanzees learn the reputation of strangers indirectly by observation? Or are such stable behavioral attributions made exclusively by first-person interactions? To address this question, we let seven chimpanzees observe unfamiliar humans either consistently give (generous donor) or refuse to give (selfish donor) food to a familiar human recipient (Experiments 1 and 2) and a conspecific (Experiment 3). While chimpanzees did not initially prefer to beg for food from the generous donor (Experiment 1), after continued opportunities to observe the same behavioral exchanges, four chimpanzees developed a preference for gesturing to the generous donor (Experiment 2), and transferred this preference to novel unfamiliar donor pairs, significantly preferring to beg from the novel generous donors on the first opportunity to do so. In Experiment 3, four chimpanzees observed novel selfish and generous acts directed toward other chimpanzees by human experimenters. During the first half of testing, three chimpanzees exhibited a preference for the novel generous donor on the first trial. These results demonstrate that chimpanzees can infer the reputation of strangers by eavesdropping on third-party interactions.     

Gender differences in the variability of lower extremity kinematics during treadmill locomotion

The authors examined whether there were gender differences in the variability of basic gait parameters (stride length, stride time) and 3-dimensional (3D) rotations of the hip, knee, and ankle joints during treadmill locomotion of 18 men and 15 women at 4 different gait speeds (walking at 5 km/hr, running at 8, 10, and 12 km/hr). The authors used 2-way analyses of variance to assess the data. No gender differences in the mean values or variability of basic gait parameters were detected. However, the women exhibited lower variability than did the men for 6 individual joint rotations: (a) transverse plane rotations of the ankle joint at 8, 10, and 12 km/hr, (b) transverse plane rotations of the hip and knee joints at 12 km/hr, and (c) sagittal plane rotations of the ankle joint at 12 km/hr. When collapsed across all 3D lower extremity rotations, the data showed that the women had lower variability than did the men at 12 km/hr. Reduced variability may result in more localized mechanical stress on anatomical structures and could therefore be a risk factor for injury in women at high gait speeds. The results also suggested that gender differences in variability may not be consistent across different levels of the motor system.     

Matching of visual input to only one item at any one time

When we perform a visual search we know what we are looking for and determine where it is. A representation of the object in our working memory, the ‘search-template’, is compared to the items in the scene until a match is found. So far it is unknown whether observers can search for multiple items at the same time. Here we compare the performance of subjects between a task in which they search for one of two target-items in a stream of visual objects and a task with only a single target. We find that search is effectively limited to one item at a time. This limitation occurs for simple and complex objects and even if the subjects have to look for two features from different domains. We conclude that matching has a fundamental capacity-limitation as the visual input can be matched to only one search-template at a time.     

Sex roles and social support as moderators of life stress adjustment

In this study we used a longitudinal design to test the stress-buffering effects of sex role orientation in combination with perceived social support on measures of trait anxiety and depression. College undergraduates served as subjects. The cross-sectional analyses provided strong support for the hypothesis that masculinity would function as a life stress buffer. The hypothesis that social support would serve as a stress buffer when coupled with high masculinity was supported by one of the cross-sectional analyses as well as the longitudinal analysis. This pattern was found primarily for perceptions of tangible social support. The longitudinal analysis also revealed a significant interaction involving negative life events and masculinity and femininity. This interaction effect provided unexpected support for a balance model of androgyny, in that non-sex-typed subjects showed greater resilience to recent life stress than did sex-typed subjects. The findings are discussed in terms of their implications for the study of life stress adjustment.     

Optimum split-half reliabilities for the Rorschach: projective techniques are more reliable than we think

A new technique for optimizing split-half reliability estimates yielded substantial and comparable increases in indexes of internal reliability for some major Rorschach variables across two diverse samples. Practical suggestions for applying this method to other projective tests were advanced. The inadvisability of computing odd-even reliability coefficients without regard to split-half distributional anomalies is addressed.     

Religiosity and the formulation of causal attributions

Researchers have suggested that religious individuals engage primarily in intuitive over analytic processing. We investigated a connection between specific aspects of religiosity and the attribution of causation to social and physical events. College undergraduates completed measures of religiosity online and were asked to determine the causes of events that varied in type, outcome, and likelihood, as well as the personality characteristics of the protagonist. Individuals with greater intrinsic religious orientation, fundamentalism, who viewed God as loving, who were more dogmatic, and had an external locus of control were more likely to attribute supernatural phenomena to events compared to those lower in those traits. Supernatural causation was invoked more often when the character of the protagonist and the outcome of social event matched in valence (both positive or both negative) than when they did not match (e.g., character positive, outcome negative). Individuals low and high in religiosity showed similar reasoning, but individuals higher in religiosity were more likely to attribute supernatural causes for positive outcomes and characters in physical scenarios, consistent with their view of God as benevolent.     

Automatic retrieval in directed forgetting

In two experiments, we investigated the role of automatic retrieval in directed forgetting, using a stem completion test. In each experiment, we compared the performance of an implicit group, a process dissociation procedure (PDP) group, and a group given a speeded response task. The response times of the speeded response group on the stem completion task replicated earlier data in suggesting that this group adopted a purely automatic retrieval strategy. Experiment 1 revealed a directed-forgetting effect on automatic retrieval with the item method, but Experiment 2 revealed no directed-forgetting effect on automatic retrieval with the list method, consistent with the lack of implicit effects with the list method throughout the literature. Both experiments showed lower automatic estimates for the PDP group than for the implicit and speeded response groups, which did not differ. The data are consistent with either a selective rehearsal or an inhibition account of directed forgetting with the list method. The comparison of methods for assessing automatic retrieval is consistent with earlier evidence suggesting that subjects may adopt a generate/recognize strategy when given direct retrieval instructions.
