Do 18-month-olds really attribute mental states to others? A critical test

In the research reported here, we investigated whether 18-month-olds would use their own past experience of visual access to attribute perception and consequent beliefs to other people. Infants in this study wore either opaque blindfolds (opaque condition) or trick blindfolds that looked opaque but were actually transparent (trick condition). Then both groups of infants observed an actor wearing one of the same blindfolds that they themselves had experienced, while a puppet removed an object from its location. Anticipatory eye movements revealed that infants who had experienced opaque blindfolds expected the actor to behave in accordance with a false belief about the object's location, but that infants who had experienced trick blindfolds did not exhibit that expectation. Our results suggest that 18-month-olds used self-experience with the blindfolds to assess the actor's visual access and to update her belief state accordingly. These data constitute compelling evidence that 18-month-olds infer perceptual access and appreciate its causal role in altering the epistemic states of other people.     

Examining the potential impact of a family session in therapeutic assessment: a single-case experiment

Most clinicians concede the benefits of conceptualizing children in systemic terms. Yet, many child assessments involve parents only on a limited basis. The Therapeutic Assessment model for children and families (TA-C) emphasizes parental involvement and family-driven collaboration throughout the intervention. Child TA has shown promise as an effective brief intervention (e.g., Smith, Handler, & Nash, 2010; Tharinger et al., 2009). Family intervention sessions (Finn, 2007; Tharinger, Finn, Austin, et al., 2008) are an integral component of the child TA model in facilitating familial changes. However, TA-C research has yet to empirically examine the potential impact of a family session on treatment trajectory. This case study includes an extended presentation of the development and execution of a family session. The authors use a daily measures time-series experiment to empirically examine the clinical effectiveness of the TA-C and the hypothesis that the family session was a tipping point in the trajectory of improvement.     

Trauma, soul murder, and change

The author discusses trauma, particularly in relation to childhood events, as well as one of its possible sequelae, soul murder (Shengold 1989, 1999). Negative interactions with parental figures can have long-term implications for the developing child, sometimes persisting into adulthood, and yet even the most loving parents cannot always behave toward the child in an optimal manner. The profound effect of change on the human psyche is also discussed, and two clinical vignettes are presented to illustrate the author's points.     

Preventing Contagion With Avian Influenza: Disease Salience,Attitudes Toward Foreigners,and Avoidance Beliefs1

Building on an evolutionary approach to out‐group avoidance, this study showed relations between perceived disease salience and beliefs in the efficacy of avoiding foreigners as protective measures in the context of a real‐life pandemic risk; i.e., avian influenza. People for whom avian influenza was salient and who held unfavorable attitudes toward foreigners were more likely to believe that avoiding contact with foreigners protects against infection. This finding suggests that individual differences in social attitudes moderate evolved mechanisms relating threat of disease to out‐group avoidance.     

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.
