Cortisol response to behavior problems in FMR1 premutation mothers of adolescents and adults with fragile X syndrome: A diathesis-stress model

Mothers of adolescents and adults with fragile X syndrome (FXS) are faced with high levels of parenting stress. The extent to which mothers are negatively impacted by this stress, however, may be influenced by their own genetic status. The present study uses a diathesis-stress model to examine the ways in which a genetic vulnerability in mothers with the premutation of the FMR1 gene interacts with child-related environmental stress to predict their morning cortisol levels. Seventy-six mothers of an adolescent or adult with FXS participated in an 8-day telephone diary study in which they reported on the behavior problems of their son or daughter with FXS each day. We analyzed salivary cortisol collected from mothers at awakening and 30 minutes after awakening on 4 of these days. The results indicated that mothers with greater genetic vulnerability had a lower level of cortisol on mornings following days when their son or daughter with FXS manifested more episodes of behavior problems, whereas mothers with less genetic risk evinced the opposite pattern of higher morning cortisol in response to their child's behavior problems. This finding contributes to our understanding of gene-by-environment interactions and highlights the importance of interventions to alleviate parenting stress in mothers raising children with FXS.     

Aging, imagery, and the bizarreness effect

ABSTRACT This study examined the bizarre imagery effect in young and older adults, under incidental and intentional conditions. Intentionality was manipulated across experiments, with participants receiving an incidental free recall test in Experiment 1 and an intentional test in Experiment 2. This study also examined the relation between working memory resources and the bizarreness effect. In Experiment 1 young and older adults were presented with common and bizarre sentences; they later received an incidental recall test. There were no age differences in sensitivity to the bizarreness effect in Experiment 1 when ANOVAs were used to analyze the data. However, when the bizarreness effect was examined in terms of effect size, there was evidence that younger adults produced larger bizarreness effect sizes than younger adults. Experiment 2 further explored age differences in sensitivity to the bizarreness effect by presenting young and older adults with bizarre and common sentences under intentional learning conditions. Experiment 2 failed to yield age differences as a function of item type (bizarre vs. common). In addition, Experiment 2 failed to yield significant evidence that the bizarreness effect is modulated by working memory resources. The results of this study are most consistent with the distinctiveness account of the bizarreness effect.     

An interview with LA Universal Self

LA Universal Self reports his phenomenology, according to which, as he puts it, ‘I am the universe’. The Interviewer challenges the report in a variety of ways, and LA Universal Self responds to each challenge. A traditional Universal Self mysticism is given a new physicalist interpretation.     

Globalization, state transformation, and educational re-structuring: why postmodern diversity will prevail over standardization

Over the past two decades the educational policies of neo-liberal nation states have exhibited contradictory tendencies, promoting both bureaucratic standardization of curriculum and standardized evaluation on the one hand, and postmodern diversification on the other. Despite recent increases in bureaucratic standardization, I argue that the economic, social and cultural effects of globalization will pressure these states towards postmodern diversification of educational arrangements to strengthen their perceived legitimacy.     

Shared suffering can mitigate aversively‐generated aggression:

Although considerable research indicates that aversive conditions (such as uncomfortably high temperatures) often evoke aggressive inclinations, there is also evidence that people are attracted to those who share their discomfort. In a 2 × 2 design, female participants in either a hot or comfortable room worked with a nearby partner exposed to the same temperature but whose reactions to the temperature were either the same as, or different from, their feelings about the temperature. The women in a fifth condition had a partner situated in a room with a comfortable temperature . Consistent with Schachter's [1959] social–emotional comparison theory, the highest level of aggression was displayed by the participants in the hot room working with a partner whose emotional reactions were different from their own, whereas their counterparts, also exposed to the high temperature but whose partner's feelings were similar to their own, exhibited the least aggression over all the trials.

Gender differences in conflict resolution styles of managers: At work and at home

Because women and men managers occupy different roles at work and at home, role theory suggests that they would use different conflict resolution behaviors in each role. This study tested this theory empirically using the Thomas-Kilmann Conflict Mode instrument to measure the five conflict resolution styles of 201 managers (99 males and 102 females) in both situational roles. Sex differences were examined along with hierarchical rank. Both genders tended to handle conflict more competitively at work than at home, and used the accommodating style more frequently at home than at work. At home, low-level women managers were more willing to collaborate and less willing to avoid conflict than at work; men managers overall were less likely to compromise at home than at work.
