Contextual amplification of pubertal transition effects on deviant peer affiliation and externalizing behavior among African American children.

The effects of the pubertal transition on behavior problems and its interaction with family and neighborhood circumstances were examined with a sample of 867 African American children 10-12 years of age. Pubertal development status, pubertal timing, and primary caregivers' parenting behaviors were significantly related to affiliation with deviant peers and externalizing behaviors. Externalizing behavior among early-maturing children was associated positively with primary caregivers' use of harsh-inconsistent discipline and negatively with nurturant-involved parenting practices. Disadvantaged neighborhood conditions were significantly associated with deviant peer affiliation. The effect of pubertal transition varied according to family and neighborhood conditions: Early-maturing children living in disadvantaged neighborhoods were significantly more likely to affiliate with deviant peers. Early-maturing children with harsh and inconsistent parents were significantly more likely to have externalizing problems.     

Individual differences in episodic memory abilities predict successful prospective memory output monitoring

Output monitoring refers to memory for one’s previously completed actions. In the context of prospective memory (PM) (e.g., remembering to take medication), failures of output monitoring can result in repetitions and omissions of planned actions (e.g., over- or under-medication). To be successful in output monitoring paradigms, participants must flexibly control attention to detect PM cues as well as engage controlled retrieval of previous actions whenever a particular cue is encountered. The current study examined individual differences in output monitoring abilities in a group of younger adults differing in attention control (AC) and episodic memory (EM) abilities. The results showed that AC ability uniquely predicted successful cue detection on the first presentation, whereas EM ability uniquely predicted successful output monitoring on the second presentation. The current study highlights the importance of examining external correlates of PM abilities and contributes to the growing body of research on individual differences in PM.     

Working memory capacity and retrieval from long-term memory: the role of controlled search

In two experiments, the role of working memory capacity (WMC) in the controlled search of long-term memory was examined. Participants performed a prolonged category fluency task that required them to retrieve as many animals as possible in 5 min. The results suggested that WMC differences arose in the numbers of animals retrieved, the numbers of clusters retrieved, and the rates of the retrieval (Exp. 1). However, no differences were found in terms of how participants initiated retrieval or in the nature of the clusters generated. Furthermore, an examination of differences in retrieval strategies suggested that high-WMC individuals were more strategic than low-WMC individuals and that these differences in retrieval strategies accounted for the overall differences in the numbers of animals retrieved. Additionally, presenting participants with retrieval cues eliminated WMC differences in the numbers of animals retrieved (Exp. 2). These results suggest that low-WMC individuals are less able than high-WMC individuals to select and utilize appropriate retrieval strategies to self-generate cues to access information in long-term memory. Collectively, the results are consistent with research suggesting that WMC is important for controlled search from long-term memory.     

Assessing Individual Differences: Effects of Responding to Prior Questionnaires on the Substantive and Psychometric Properties of Self-Esteem and Depression Assessments

It has become a common practice among psychological researchers to administer batteries of individual difference assessments to research participants, although little is known about whether the substantive and psychometric integrity of the questionnaires are maintained when they are administered after the subject has completed other instruments. The studies presented here consider these issues in relation to the assessment of self-esteem and depression. In the first study, college students responsed to a self-esteem inventory (a) by itself (control group), (b) after one prior questionnaire, (c) after three prior questionnaires, or (d) after five prior questionnaires. Results indicated that filling out one or more questionnaires before an assessment of self-esteem resulted in repots of lower self-esteem relative to the control condition. Additional analyses revealed that filling out three or five prior questionnaires created lower reliabilities of subscale scores and lower estimates of concurrent validity between self-esteem and depression. When the effect of prior questionnaires on the General Self-Esteem subscale was examined, the aforementioned results were replicated, and the prior questionnaire treatment created heterogeneous variances across the experimental groups. The second study was designed as a replication of the first study, using an assessment of depression as the target questionnaire. These results revealed that reports of depressive symptomatology increased as the number of prior questionnaires increased. Again, the prior or questionnaire treatment created heterogeneity of variance between the groups, but did not adversely affect its internal consistency.     

Treatment of a four-year-old victim of incest

Abstract

A case study describing the use of behavior techniques in the treatment of a four—year—old sexual assault victim is presented. The target behaviors included eating, phobic behaviors, self—injurious behaviors, and comments made about the father (the perpetrator) and the paternal grandmother. The child's mother served as both data collector and therapist. The study demonstrates that child victims can experience a sexual assault trauma syndrome similar to that manifested by adult victims. Additionally, the findings illustrate that a simple behavioral intervention implemented by a parent can be effective in treating young sexual assault victims.     

The effects of free recall testing on subsequent source memory

The testing effect is the finding that prior retrieval of information from memory will result in better subsequent memory for that material. One explanation for these effects is that initial free recall testing increases the recollective details for tested information, which then becomes more available during a subsequent test phase. In three experiments we explored this hypothesis using a source-monitoring test phase after the initial free recall tests. We discovered that memory is differentially enhanced for certain recollective details depending on the nature of the free recall task. Thus further research needs to be conducted to specify how different kinds of memorial details are enhanced by free recall testing.     

A meta-analysis of burnout with job demands, resources, and attitudes

A meta-analysis was conducted on job demands, resources, and attitudes and their relation with burnout in regard to the COR theory. The version of the Maslach Burnout Inventory used was explored as a moderator of the aforementioned variables. Results suggest that higher demands, lower resources, and lower adaptive organizational attitudes are associated with burnout. In particular, results of the current study show stronger relations than previous meta-analysis (Lee & Ashforth, 1996) have suggested. The scale type also provided some evidence of moderation, with stronger effects found in samples that utilized the MBI-HSS. Implications of the findings in relation to the COR theory and future research directions to clarify the relation between job demands, job resources, organizational attitudes and burnout are discussed.
