The relation between mother–infant coordinated interpersonal timing, an automated microanalytic measure of dyadic vocal coordination, and maternal sensitivity was explored. Thirty-five mothers and their developmentally normal 4-month-old infants were audio-recorded during a 20-min laboratory vocal interaction session, that was later analyzed for degree of vocal coordination. Maternal Sensitivity ratings (Ainsworth & Bell, 1969) were based on a video-taped 45-min unstructured laboratory interaction period. A significant curvilinear relation between the degree to which mother coordinated her noninterruptive co-occurring speech to that of her infant was found and revealed that mothers highest in sensitivity were characterized by moderate levels of coordination. Examining mother-infant interaction at the specific behavioral level, while incorporating tests of nonlinear trends, may provide important information about the nature of sensitive parenting.  相似文献

In 1877 Thomas Barlow, a London physician, published a remarkable case of functional recovery of speech following brain damage. It involved a 10-year-old boy who had lost his speech, regained it, and lost it again before he died from a disorder that affected his heart and produced embolisms that subsequently affected other organs, including his brain. Examination of the boy's brain revealed two focal regions of softening; one that affected Broca's area and the left facial-motor area, and another, which occurred weeks later, in the homologous regions of the right hemisphere. Although Barlow was most concerned with motor deficits, others at the turn of the century began to cite this case as strong evidence that the corresponding region of the right hemisphere can take over speech functions for Broca's area on the left. Whether this case really provides good support for functional takeover or vicariation theory is critically evaluated in the light of contemporary research, including PET scan studies involving damage to Broca's speech region.  相似文献

A theory of diversity in speeded cognition, the difference engine, is proposed, in which information processing is represented as a series of generic computational steps. Some individuals tend to perform all of these computations relatively quickly and other individuals tend to perform them all relatively slowly, reflecting the existence of a general cognitive speed factor, but the time required for response selection and execution is assumed to be independent of cognitive speed. The difference engine correctly predicts the positively accelerated form of the relation between diversity of performance, as measured by the standard deviation for the group, and task difficulty, as indexed by the mean response time (RT) for the group. In addition, the difference engine correctly predicts approximately linear relations between the RTs of any individual and average performance for the group, with the regression lines for fast individuals having slopes less than 1.0 (and positive intercepts) and the regression lines for slow individuals having slopes greater than 1.0 (and negative intercepts). Similar predictions are made for comparisons of slow, average, and fast subgroups, regardless of whether those subgroups are formed on the basis of differences in ability, age, or health status. These predictions are consistent with evidence from studies of healthy young and older adults as well as from studies of depressed and age-matched control groups.  相似文献

To expand the collection of instruments available for assessment of anxiety in the elderly, this report examined the original and revised Hamilton anxiety scales in a sample of 50 older adults diagnosed with Generalized Anxiety Disorder (GAD) and 93 normal community participants (ages 55–82). Although the revised anxiety scale had better discriminant validity (lower correlation with the revised Hamilton depression scale) than the original anxiety and depression scales, a considerable amount of shared variance still existed (41% shared variance, GAD sample alone; 17% control sample alone; 74% shared variance, both samples combined). Near-perfect group classification was possible using 7 items from the original anxiety scale and 10 items from the revised anxiety scale. Results are discussed in light of their implications for use of the Hamilton anxiety rating scale with older anxiety-disordered patients.  相似文献

The purpose of this qualitative study was to investigate the use of strategies for managing suicide-related events (SREs; i.e., suicide deaths, suicide attempts, and suicidal ideation with a plan and intent to die) during deployment from the perspective of Army decision makers: behavioral health providers (BHPs), chaplains, and leaders. A total of 76 Army personnel participated in individual interviews or focus groups. Participants identified unit watch, weapon removal, medical evacuations, and debriefings as common strategies used to manage SREs in deployed settings. Many of these strategies were highlighted as short-term solutions only. Participants also underscored the importance of unit cohesion and communication among leaders, BHPs, and chaplains to effectively manage SREs. The need for structured guidelines for successfully managing SREs in deployed settings is discussed.  相似文献

Benchmarking is a program evaluation approach that can be used to study whether the outcomes of parents/children who participate in an evidence-based program in the community approximate the outcomes found in randomized trials. This paper presents a case illustration using benchmarking methodology to examine a community implementation of Parent–Child Interaction Therapy (CI-PCIT) utilized as a child maltreatment prevention effort. Data were collected from 83 parent–child dyads. Change scores were compared to treatment and control effect sizes aggregated from the PCIT literature. Pre-post results indicated significant positive changes in child behavior for CI-PCIT completers. Benchmarking analyses revealed that parents who completed CI-PCIT reported significantly greater positive child outcomes than the aggregate control group benchmark, and significantly less than observed in the treatment benchmark. A summary of decision points and implications for utilizing this methodology in the child maltreatment field are postulated.  相似文献

Objectives

In the present study, we tested a model examining the relationships between exercise imagery use, motivational regulations for exercise engagement, intention to exercise, and self-reported exercise behavior. This work represents an initial attempt to examine relationships between a new type of exercise imagery (enjoyment imagery) and motivational regulations for exercise.

Design

Cross-sectional.

Method

Exercisers with a mean age of 40.29 years (SD = 13.29; 177 female, 141 male) completed measures of the targeted variables.

Results

Structural equation modeling analyses revealed direct and indirect (via motivational regulations) links between imagery and exercise-related outcomes. Technique and enjoyment imagery were positively related to autonomous motivation. Conversely, appearance imagery was positively associated with controlled motivation. Direct relationships were evidenced between energy imagery and self-reported exercise behavior, and between appearance imagery and intention to exercise.

Conclusions

The potential motivational functions served by different exercise imagery types are discussed, and the inclusion of enjoyment imagery in future exercise imagery research is recommended.  相似文献

This study uses meta-analytic methods to explore programmatic moderators or common factors of the effectiveness of marriage and relationship education (MRE) programs. We coded 148 evaluation reports for potential programmatic factors that were associated with stronger intervention effects, although the range of factors we could code was limited by the lack of details in the reports. Overall, we found a positive effect for program dosage: moderate-dosage programs (9-20 contact hours) were associated with stronger effects compared to low-dosage programs (1-8 contact hours). A programmatic emphasis on communication skills was associated with stronger effects on couple communication outcomes, but this difference did not reach statistical significance for the relationship quality/satisfaction outcome. There was no evidence that institutionalized MRE programs (formal manuals, ongoing presence, formal instructor training, multiple evaluations) were associated with stronger effects. Similarly, there was little evidence of differences in program setting (university/laboratory vs. religious). We discuss possible explanations for these findings and implications for program design and evaluation.  相似文献

The goal of this study was to investigate individual and relationship influences on expressions of negativity and positivity in families. Parents and adolescents were observed in a round-robin design in a sample of 687 families. Data were analyzed using a multilevel social relations model. In addition, genetic contributions were estimated for actor effects. Children showed higher mean levels of negativity and lower mean levels of positivity as actors than did parents. Mothers were found to express and elicit higher mean levels of positivity and negativity than fathers. Actor effects were much stronger than partner effects, accounting for between 18%-39% of the variance depending on the actor and the outcome. Genetic (35%) and shared environmental (19%) influences explained a substantial proportion of the actor effect variance for negativity. Dyadic reciprocities were lowest in dyads with a high power differential (i.e., parent-child dyads) and highest for dyads with equal power (sibling and marital dyads).  相似文献
