The wane of childhood amnesia for autobiographical and public event memories

We modified Bruce, Dolan, and Phillips-Grant's (2000) threshold procedure for determining the wane of childhood amnesia. In two experiments, undergraduates labelled childhood events (e.g., your first permanent tooth came in) as know or recollect memories and estimated their age at the event's occurrence. In both studies the estimated transition from mostly know memories to mostly recollect memories was roughly 4.7 years. This transition estimate was replicated in a sample of adults (ages 24-65 years) with both Bruce et al.'s event-generation task and the Experiment 1a questionnaire. By contrast, in two experiments a transition estimate of roughly 6 years was found for undergraduates' memories of public events (e.g., the Challenger explosion). The wane of childhood amnesia appears to occur around 4.7 years.     

Item method directed forgetting diminishes false memory

Directed forgetting may reduce the ORM false memory illusion by interfering with meaning processing. Participants were presented with a list composed of six 10-word semantically associated sub-lists, and they were either (a) asked to remember a ll list it ems or (b) asked to remember all associates from sub-lists and to forget all associates from other sub-lists. All participants were requested to recall and recognise list items. Although directed forgetting effects have been previously reported only for true responses in the ORM paradigm with the list method, we also found directed forgetting for false responses with the item method. Such forgetting instructions reduced both verbatim and meaning processing, decreasing both the intrusion and the false alarm rate. These results are consistent with two-process explanations of DRM false memories, such as fuzzy-trace theory, and add to our understanding of false memory editing.     

The Effects of Socio‐Economic Status on Infant Attention

The development of visual attention is a key component of cognitive functioning in infancy and childhood. By the time children in poverty reach school, deficits in attention are readily apparent; however, when these attention delays manifest is unknown. The current study tested attention longitudinally at 6, 9 and 12 months in infants from high‐socio‐economic status (SES) and low‐SES families. Infants were tested in a free play attention task in both simple and complex conditions, and two measures each of attention and inattention were scored. High‐SES infants showed greater attention overall and greater increases in attention when the stimuli were more complex. Low‐SES infants showed higher inattention than their high‐SES peers at all ages and were less likely to modulate their attention on the basis of stimulus complexity. Thus, by 6 months of age, low‐income infants already show deficits in attention. Results are discussed in terms of adaptability, implications for social development and attention interventions.

Conscious and Unconscious Use of Self: The Evolution of a Process

Recent emphasis has been placed on the central role of the therapeutic relationship in successful treatment. One aspect of the development of an effective relationship is the clinical social worker's use of self. We argue that the use of self happens both consciously and unconsciously and is a dynamic and evolving process in psychotherapy. This evolution can result in the clinical social worker shifting from a stance of doing to being. Drawing from a Japanese tradition of learning, three stages of learning provide a framework for understanding how therapists may transition from a state of doing to being in the therapy. Through this process, the conscious use of self may develop into unconscious use of self. Two case examples demonstrate how expanding and using one's self-awareness and the new knowledge through meaningful learning experiences can shift a clinical social worker's ability to develop and enhance his or her use of self, inviting therapeutic presence and depth.     

Testing an extended theory of planned behavior to predict young people's intentions to join a bone marrow donor registry

An extended theory of planned behavior (TPB) was used to understand the factors, particularly control perceptions and affective reactions, given conflicting findings in previous research, informing younger people's intentions to join a bone marrow registry. Participants (N = 174) completed attitude, subjective norm, perceived behavioral control (PBC), moral norm, anticipated regret, self‐identity, and intention items for registering. The extended TPB (except PBC) explained 67.2% of variance in intention. Further testing is needed as to the volitional nature of registering. Moral norm, anticipated regret, and self‐identity are likely intervention targets for increasing younger people's bone marrow registry participation.     

Finite Mixtures for Simultaneously Modeling Differential Effects and Nonnormal Distributions

Regression mixture models have been increasingly applied in the social and behavioral sciences as a method for identifying differential effects of predictors on outcomes. Although the typical specification of this approach is sensitive to violations of distributional assumptions, alternative methods for capturing the number of differential effects have been shown to be robust. Yet, there is still a need to better describe differential effects that exist when using regression mixture models. This study tests a new approach that uses sets of classes (called differential effects sets) to simultaneously model differential effects and account for nonnormal error distributions. Monte Carlo simulations are used to examine the performance of the approach. The number of classes needed to represent departures from normality is shown to be dependent on the degree of skew. The use of differential effects sets reduced bias in parameter estimates. Applied analyses demonstrated the implementation of the approach for describing differential effects of parental health problems on adolescent body mass index using differential effects sets approach. Findings support the usefulness of the approach, which overcomes the limitations of previous approaches for handling nonnormal errors.     

Understanding the emotional past: relations between parent and child contributions in emotionally negative and nonnegative events

The past event conversations of 33 mothers with their 3-year-old children (18 girls and 15 boys) were selected from a larger sample based on their discussion of negative events. Negative events included both those that were negative in topic and those that contained negative incidents but were otherwise positively themed. Within-subjects comparisons were made between the negative events and a neutral or positive event. There were few differences in how mothers and their children talked about negative and nonnegative events. Children did include more interpretations (internal state and causal references) in their negative event conversations. For both event types, mothers who talked more about the past events had children who reported more. When maternal talkativeness was controlled, involving children in the negative event conversations through deflecting the conversational turn predicted children's total contributions and number of interpretations. Repeating information and requests for information while constraining the topic was negatively related to the number of details children reported for nonnegative past events. Conversations about minor negative experiences demonstrate that mothers can influence children's involvement in discussions and understanding of the past.     

Culture and social support: who seeks it and why?

Are Asians and Asian Americans more or less likely to seek social support for dealing with stress than European Americans? On the one hand, the collectivist orientation of Asian countries might favor the sharing of stressful problems; on the other hand, efforts to maintain group harmony might discourage such efforts. In 2 studies, Koreans (Study 1) and Asians and Asian Americans in the United States (Study 2) reported using social support less for coping with stress than European Americans. Study 3 examined potential explanations for these effects and revealed that relationship concerns accounted for the cultural differences in use of support seeking. Discussion centers on the potential benefits and liabilities of seeking social support.     

When what you know is not enough: expertise and gender dynamics in task groups

This study investigates how the contribution, identification, and consideration of expertise within groups are affected by gender differences. The authors examined the effects of member expertise and gender on others' perceptions of expertise, actual and own perceptions of influence, and group performance on a decision-making task. The authors' findings are consistent with social role theory and expectation states theory. Women were less influential when they possessed expertise, and having expertise decreased how expert others perceived them to be. Conversely, having expertise was relatively positive for men. These differences were reflected in group performance, as groups with a female expert underperformed groups with a male expert. Thus, contrary to common expectations, possessing expertise did not ameliorate the gender effects often seen in workgroups. The findings are discussed in light of their implications for organizational workgroups in which contribution of expertise is critical to group performance.
