Children's Use of Mnemonic Strategies: Variability in Response to Metamemory Training

In this study, 8- to 12-year-old children were tested to determine their level of use of a strategy for organizing lists of low-associated words into semantic groups. Then, on the basis of their scores in the strategy tests, the children were placed in either a strategic or nonstrategic group. The groups were divided into a sort-instruction training condition, in which they were told to group words so that they “go together” in some way, and a metamemory training condition, in which these instructions were supplemented by feedback, strategy reminders, and opportunities to self-test. One week later, each child's strategy use was reassessed. Children in the strategic group sorted semantically throughout training and transfer, and they showed high recall, regardless of condition. Children in the nonstrategic group showed high strategy use and recall during training, but they showed significantly more variability in recall than did the children in the strategic group. Children in the nonstrategicmetamemory condition who benefited from training were also more likely to transfer the use of the strategy than were children trained in the sort-instruction condition.     

Freely Chosen Index Finger Tapping Frequency Is Increased in Repeated Bouts of Tapping

Healthy individuals (n = 40) performed index finger tapping at freely chosen frequency during repeated bouts and before and after near-maximal muscle action consisting of 3 intense flexions of the index finger metacarpal phalangeal joint. One experiment showed, unexpectedly, that a bout of tapping increased the tapping frequency in the subsequent bout. Thus, a cumulating increase of 8.2 ± 5.4% (p < .001) occurred across 4 bouts, which were all separated by 10 min rest periods. Follow-up experiments revealed that tapping frequency was still increased in consecutive bouts when rest periods were extended to 20 min. Besides, near-maximal muscle activation, followed by 5 min rest, did not affect the tapping frequency. In conclusion, freely chosen tapping frequency was increased in repeated bouts of tapping, which were separated by 10–20 min rest periods. The observed phenomenon is suggested to be termed repeated bout rate enhancement.     

How simulations fail

‘The problem with simulations is that they are doomed to succeed.’ So runs a common criticism of simulations—that they can be used to ‘prove’ anything and are thus of little or no scientific value. While this particular objection represents a minority view, especially among those who work with simulations in a scientific context, it raises a difficult question: what standards should we use to differentiate a simulation that fails from one that succeeds? In this paper we build on a structural analysis of simulation developed in previous work to provide an evaluative account of the variety of ways in which simulations do fail. We expand the structural analysis in terms of the relationship between a simulation and its real-world target emphasizing the important role of aspects intended to correspond and also those specifically intended not to correspond to reality. The result is an outline both of the ways in which simulations can fail and the scientific importance of those various forms of failure.

Critical Hopefulness: A Person-Centered Analysis of the Intersection of Cognitive and Emotional Empowerment

Leaders in struggles for social justice agree on the importance and the difficulty of maintaining hopefulness while developing critical awareness of social issues. Research has indicated that the analogous components of psychological empowerment (emotional and cognitive) often do not co-vary across populations. This study used a person-centered analytic approach, latent class analysis, to identify subpopulations of participants (n = 1,322) according to the cognitive and emotional components of psychological empowerment. Four distinct sub-groups emerged: those who were relatively (1) critical but alienated, (2) uncritical but hopeful, (3) uncritical and alienated, or (4) critical and hopeful. These clusters were then examined for demographic differences and relationships with a set of conceptually relevant variables including social capital, psychological sense of community, openness, organizational participation and mental wellbeing. Results shed light on the complexity of empowerment processes and yield implications for ongoing community research and action.     

Effects of Multiple Maternal Relationship Transitions on Offspring Antisocial Behavior in Childhood and Adolescence: A Cousin-Comparison Analysis

Previous studies of the association between multiple parental relationship transitions (i.e., when a parent begins or terminates an intimate relationship involving cohabitation) and offspring antisocial behavior have varied in their efforts to rule out confounding influences, such as parental antisocial behavior and low income. They also have been limited in the representativeness of their samples. Thus, it remains unclear to what degree parents’ multiple relationship transitions have independent effects on children’s antisocial behavior. Analyses were conducted using data on 8,652 6–9-year-old, 6,911 10–13-year-old, and 6,495 14–17-year-old offspring of a nationally representative sample of U.S. women. Cousin-comparisons were used in combination with statistical covariates to evaluate the associations between maternal relationship transitions and offspring antisocial behavior in childhood and adolescence. Cousin-comparisons suggested that associations between maternal relationship transitions and antisocial behavior in childhood and early adolescence are largely explained by confounding factors. In contrast, the associations between maternal relationship transitions and offspring delinquency in late adolescence were robust to measured and unmeasured confounds. The present findings suggest that interventions aimed at reducing exposure to parental relationship transitions or addressing the psychosocial consequences of exposure to parental relationship transitions could reduce risk for offspring delinquency in late adolescence.     

Predictors of Entry into Age-Discordant Relationships Among Adolescent Girls

Teenage girls in age-discordant relationships remain of concern for healthy development and well-being. We examine whether factors from several sociological frameworks—self-esteem, deviance, social ecology, family cohesion, and religious involvement—predict entry into such relationships. With longitudinal data on 1,537 adolescent girls, we use structural equation modeling to assess risk and protective factors by age group. Results indicate that few social factors predict entry to such relationships; only religious involvement for the youngest adolescents and self-esteem for middle adolescents predict entry. While adolescent girls who date older males are largely like their peers, any impact of social factors may vary by the developmental stage that adolescent girls occupy.
