Development of upper limb proprioceptive accuracy in children and adolescents

This study was designed to determine differences in the proprioceptively guided movements of children (8-10 years) and adolescents (16-18 years). Participants were blindfolded and asked to actively match passively determined target positions of the elbow joint under three matching conditions. Overall, children were less accurate than adolescents in all matching tasks and utilized different kinematic strategies for making the matching movements. Specifically, children made larger absolute errors and utilized matching movements which, compared to adolescents, were of shorter duration and less irregular in terms of their velocity profiles. An assessment of limb asymmetry was also performed revealing a non-dominant arm matching advantage but only for children and only in the task requiring interhemispheric transfer of a memory-based model of limb position. The proprioceptive differences observed in this study are likely the result of experience-driven refinement in the utilization of somatosensory feedback throughout childhood and into adolescence.     

The Relative Contribution of Sibling Deviance and Peer Deviance in the Prediction of Substance Use Across Middle Childhood

This study investigated the quality of sibling relationships and sibling deviancy in a sample of children at-risk for substance use and antisocial behavior. Based on a history of empirical and theoretical models suggesting strong associations between children's development in the context of relationships and the emergence of delinquency and drug use, this research extends previous efforts by including sibling relationships in this developmental model, linking siblings with later substance use. Sibling relationship quality as well as peer deviance were examined using a multirater, multimethod assessment procedure. We tested 3 constructs (deviancy, warmth, and conflict) related to sibling behavior. Only sibling deviance and peer deviance directly predicted substance use. When both sibling deviance and peer deviance were examined as predictors of changes in substance use over time, only sibling deviance was significant. Implications for the development of substance use behavior in middle childhood are discussed.     

An analysis of initial acquisition and maintenance of sight words following picture matching and copy cover, and compare teaching methods

This study compared the copy, cover, and compare method to a picture-word matching method for teaching sight word recognition. Participants were 5 kindergarten students with less than preprimer sight word vocabularies who were enrolled in a public school in the Pacific Northwest. A multielement design was used to evaluate the effects of the two interventions. Outcomes suggested that sight words taught using the copy, cover, and compare method resulted in better maintenance of word recognition when compared to the picture-matching intervention. Benefits to students and the practicality of employing the word-level teaching methods are discussed.     

Client-level predictors of adherence to MST in community service settings

This study examined the association of youth and family characteristics with therapist fidelity to an evidence-based treatment provided in real world practice settings. Participants were 233 families that reported on the 66 therapists organized into 16 teams in nine organizations providing multisystemic therapy (MST). Therapist adherence ratings were lower for youths referred for both criminal offenses and substance abuse than for youths referred either for substance abuse or status offenses, and was negatively associated with pretreatment arrests and school suspensions. Adherence ratings were positively associated with educational disadvantage and caregiver-therapist ethnic match and marginally positively associated with economic disadvantage. The findings suggest directions for future research on the implementation of evidence-based treatments in community settings.     

Personal Strategies for HIV Prevention: The Development and Validation of a Strategy-Coding Instrument1

This paper describes the development of a coding instrument to classify college students' strategies for preventing HIV infection, and examines the association of distinct strategies with social cognitive and behavioral measures related to safer sexual behavior. This instrument classifies each strategy into both a content domain (e.g., using condoms, remaining abstinent, limiting sexual partners), and 3 distinct dimensions: commitment, specificity, and effectiveness. We examine the reliability and validity of this instrument by showing the discriminative associations of each dimension with social cognitive and behavioral measures, and demonstrate the differential importance of distinct dimensions in predicting behavior in different content domains. Discussion focuses on the importance of tailoring HIV prevention messages to change strategy dimensions in order to maximize behavior change.     

Variations in constrained retrieval

Mentally reinstating encoding operations at retrieval might improve access to memories; however, such constrained retrieval is an effortful process that may not always be used. The memory-for-foils procedure (Jacoby, Shimizu, Daniels, & Rhodes, Psychonomic Bulletin & Review 12, 852-857, 2005) infers participant-initiated mental reinstatement of encoding operations during attempts at recognition from the differential memory that accrues to foils during a test of deeply processed items versus during a test of shallowly processed items, as indicated by performance on a final recognition memory test for the foils. Experiment 1 tested whether differential memory for foils is due to the evocation of task context during recollection of neighboring old items. Experiment 2 tested whether inducing a set to respond without much effort on a prior recognition test affects the likelihood of constrained retrieval on later tests. Experiment 3 tested whether constrained retrieval is less likely to occur when the deep versus shallow source of test items is intermixed, rather than blocked in separate tests. These experiments provide evidence that people query memory by mentally reinstating encoding operations and identify conditions that affect the probability of constrained retrieval.     

Stalking Myth-Attributions: Examining the Role of Individual and Contextual Variables on Attributions in Unwanted Pursuit Scenarios

Undergraduates from a large southeastern university in the U.S. (n?=?258) read a scenario describing an unwanted heterosexual pursuit that manipulated story perspective (pursuer’s vs. rejecter’s) and pursuer/rejecter gender. Measures of 1) external attributions for pursuer behavior, 2) negative internal attributions to rejecters, and 3) Stalking Myths endorsement followed. Individuals adopting the pursuer’s perspective showed higher rates of external attributions for pursuer behavior than those in the rejecter perspective condition. They also endorsed more negative internal attributions for rejecters than those in the rejecter perspective condition, especially when the rejecter was male. Participant gender also mattered. Men exhibited more victim blaming tendencies than women when the rejecter was female. However, stalking myth endorsement was the strongest predictor of attributions.     

Sex differences in the relation between math performance, spatial skills, and attitudes

Sex differences have been previously found in cognitive and affective predictors of math achievement, including spatial skills and math attitudes. It is important to determine whether there are sex differences not only in the predictors themselves, but also in the nature of their relation to math achievement. The present paper examined spatial skills and math attitudes as predictors of curriculum-based measures of math performance in middle-school students, specifically comparing the patterns of these predictive relations for boys and girls. The results of the current study showed that, despite similar levels of math performance for boys and girls, the significance of particular predictors varied as a function of sex. Specifically, spatial skills predicted math performance in boys, but not in girls. We suggest that sex differences in spatial reasoning in conjunction with the differential involvement of spatial reasoning in math problem solving may lead to later sex differences in math outcomes.     

The Oneness Beliefs Scale: Connecting Spirituality with Pro‐Environmental Behavior

The inherent unity of all phenomena, or oneness, is a central concept of mysticism, but there have heretofore been no measures of oneness beliefs. We developed the Oneness Beliefs Scale, with spiritual and physical oneness subscales. The spiritual oneness subscale fills a need in the field for a short, reliable measure of spirituality not characterized by the language of traditional Western religiousness. The physical oneness subscale allows researchers to juxtapose spiritual beliefs with a nonspiritual, materialist counterpart. We found that spiritual oneness beliefs were more strongly related to mystic experiences and spirituality than to traditional religiousness. Physical oneness was not strongly associated with either religiousness or spirituality. Both spiritual and physical oneness were positively associated with pro‐environmental attitudes but not with depression, anxiety, or negative affect. Spiritual oneness was a better predictor of pro‐environmental attitudes than was religiousness. Spiritual oneness also predicted donating to a pro‐environmental group, making this to our knowledge the first empirical study to show a positive association between a religion or spirituality measure and observed, rather than self‐reported, pro‐environmental behavior.     

Adapting Parent–Child Interaction Therapy for Deaf Families That Communicate via American Sign Language: A Formal Adaptation Approach

While our field has made positive strides in adapting psychotherapeutic interventions for diverse groups of people, considerable work is still needed in this area. We present our formal adaptation procedure for parent–child interaction therapy (PCIT) with Deaf persons. This includes a review of the cultural adaptation process for psychological interventions, including PCIT, as well as an introduction to Deaf culture. Details regarding the specific adaptation of PCIT for Deaf persons are outlined. We found that the utilization of a clear framework to guide the cultural adaptation process facilitated careful consideration of the numerous linguistic and cultural variables involved, while maintaining integrity of the treatment model. While the current focus was on adapting PCIT for Deaf families who communicate via American Sign Language, this framework can also be applied to other populations and/or interventions.
