Is It What You Do,or When You Do It? The Roles of Contingency and Similarity in Pro‐Social Effects of Imitation

Being imitated has a wide range of pro‐social effects, but it is not clear how these effects are mediated. Naturalistic studies of the effects of being imitated have not established whether pro‐social outcomes are due to the similarity and/or the contingency between the movements performed by the actor and those of the imitator. Similarity is often assumed to be the active ingredient, but we hypothesized that contingency might also be important, as it produces positive affect in infants and can be detected by phylogenetically ancient mechanisms of associative learning. We manipulated similarity and contingency between performed and observed actions in a computerized task. Similarity had no positive effects; however, contingency resulted in greater enjoyment of the task, reported closeness to others, and helping behavior. These results suggest that the pro‐social effects of being imitated may rely on associative mechanisms.     

A Brief Parenting Intervention to Enhance the Parent–Child Relationship in Hong Kong: Harmony@Home

There is a dearth of high-level evidence for brief programs designed to promote positive parent–child relationships in nonwestern cultures. We present a pilot randomized controlled trial of a four-session intervention to enhance the parenting skills that promote a positive relationship with pre-adolescent children in Hong Kong. Our intervention, Harmony@Home, utilized Cunningham’s culturally appropriate coping modeling, problem-solving approach to change parental behavior. Our objective was to evaluate the feasibility, acceptability and initial evidence of benefit of the intervention. We blindly randomized 150 Hong Kong parents of children 10–13 years of age to (a) a Harmony@Home intervention group, (b) a waitlist control group, or (c) a third active intervention which shared the control group. Immediately following the intervention, we report increases in satisfaction with the parent–child relationship, one of the targeted parenting behaviors and family harmony, for the Harmony@Home group versus control group. However, only the results from satisfaction with the parent–child relationship were significant at 3-months post intervention. Most respondents reported high levels of program satisfaction. The results provide preliminary evidence that this parenting intervention is culturally acceptable for a nonwestern general population, is feasible for implementation in a community setting and shows evidence of benefit. This intervention is concordant with public health priorities because of the global importance of the parent–child relationship as a protective factor for adolescent outcomes, the need for culturally-appropriate interventions for nonwestern populations, and design characteristics that promote dissemination.     

Effects of contextual interference on learning technical sports skills.

The effects of contextual interference on learning skills of volleyball (volley, bump, serve) are influenced by the scheduling of actual practice sessions: the activities can be proposed in a repetitive practice schedule (blocked practice) by continuously repeating the same task (low interference) or in random practice schedules by performing more tasks or variations of one same activity (high interference). High contextual interference, even though causing immediate limited performance, leads to superior performance on retention and transfer tests. Four experimental groups (13 students each) were placed in conditions of random, blocked, serial, and serial with high interference practice for 8 meetings (2 tests and 6 practice). Analysis yielded significant differences among the groups on a transfer test (long transfer) for the serve, so results in this instructional setting are partially in line with those generally found in laboratory experiments.     

The Meaning of Childbearing Among IVF Service Users Assessed via Laddering Technique

The psychosocial issues related to infertility have been widely researched. However, the meaning a couple gives to childbearing remains a relatively unexplored area. This study explores the meaning making of Hong Kong Chinese couples who had received in-vitro fertilization (IVF). Eleven IVF-successful and seven IVF-unsuccessful informants were assessed using two complementary constructivist methods: laddering technique and constructivist-grounded theory analysis of in-depth interviews. Findings revealed four aspects of symbolic meaning of childbearing focused on the informant's sense of self, cultural values, existential purpose, and relations with others. The results also depicted infertility as a form of disenfranchised grief, following ambiguous loss, underscoring the need for counselors to explore the meaning of childbearing among IVF service users and the impact on their self-narratives as a function of treatment outcome.
