AD/HD Symptoms and Conduct Problems: Similarities and Differences in Maternal Perceptions

Several theories attempt to explain the high co-occurrence of Attention Deficit/ Hyperactivity Disorder (AD/HD) and Conduct Problems (CP). A strong possibility is that AD/HD behaviours lead to the development of CP, due to family coercive interaction patterns, maintained through parental false beliefs regarding child problem behaviour. We compared maternal perceptions about AD/HD behaviors and CP, and the possible reactions elicited by such behaviours. The sample consisted of 317 mothers of boys and girls aged 4–6. Four versions of The Parental Account of the Causes of Childhood Problems Questionnaire were used, in which a vignette was ascribed to either a boy or a girl displaying some of the major AD/HD behaviours or CP. The results showed that CP were perceived as significantly more severe than AD/HD behaviours. Moreover, AD/HD behaviours were attributed to biological causes more often than CP, and less strict rearing practices were chosen for AD/HD symptoms. Our findings provide evidence that mothers usually perceive AD/HD behaviours and CP as separate entities and may behave accordingly with their children.     

Predicting the suicide attempts of lesbian, gay, and bisexual youth

In this study predictors of serious suicide attempts among lesbian, gay, and bisexual (LGB) youth were examined. Three groups were compared: youth who reported no attempts, youth who reported attempts unrelated to their sexual orientation, and youth whose attempts were considered related to their sexual orientation. About one third of respondents reported at least one suicide attempt; however, only half of the attempts were judged serious based on potential lethality. About half of all attempts were related to youths' sexual orientation. Factors that differentiated youth reporting suicide attempts and those not reporting attempts were greater childhood parental psychological abuse and more childhood gender-atypical behavior. Gay-related suicide attempts were associated with identifiability as LGB, especially by parents. Early openness about sexual orientation, being considered gender atypical in childhood by parents, and parental efforts to discourage gender atypical behavior were associated with gay-related suicide attempts, especially for males. Assessment of past parental psychological abuse, parental reactions to childhood gender atypical behavior, youths' openness about sexual orientation with family members, and lifetime gay-related verbal abuse can assist in the prediction of suicide attempts in this population.     

Re-examining the contribution of visuospatial working memory to inhibition of return

Castel and colleagues (Percept Psychophys 65(6):970–981, 2003) proposed that visuospatial working memory is needed to retain and update the irrelevant but attended location in an inhibition of return (IOR) procedure. In a series of three experiments, we re-examined this hypothesis by loading visuospatial working memory and manipulating the timing of encoding. When the visuospatial memory items were presented right after the cue, as in Castel et al. (Percept Psychophys 65(6):970–981, 2003), we replicated the lack of IOR in the dual-task condition (Experiment 1). However, when we presented the visuospatial memory items before the spatial cue, to control for retroactive interference in encoding, we found robust IOR effects (Experiment 2); the effect remained strong even when participants were prevented from using verbal labels to rehearse the memory material (Experiment 3). We conclude that IOR does not seem to depend on retaining the position of the irrelevant cue in visuospatial working memory.     

Powerless people don't yell but tell: The effects of social power on direct and indirect expression of anger

Expressing anger can engender desired change, but it can also backfire. In the present research we examined how power shapes the expression of anger. In Study 1, we found that powerless individuals were less inclined to express their anger directly but more inclined to express it indirectly by sharing it with others. Powerless participants’ reluctance to express anger directly was mediated by negative social appraisals. In Study 2, we replicated the effect of power on direct anger expression in a situation in which participants had actual power (or not). Anger was evoked in the laboratory using an ecologically valid procedure, and participants were given an opportunity to express anger. Study 3 showed that powerless participants expected direct anger expression to arouse more anger than fear in the target, whereas the opposite was true for indirect anger expression. Powerful participants always expected to elicit more fear than anger in the target.
