Bidirectional influences in mother–toddler dyads: an examination of the relative influence of mothers' and children's behaviours

This study examined bidirectional relationship between mothers' lax and overreactive discipline and children's misbehaviour and negative effect. We examined the moment‐to‐moment stability of mothers' and children's behaviours (actor effects) and mothers' and children's influence on their partners' subsequent behaviours (partner effects). Participants were 71 mothers and their 24‐ to 48‐month‐old children observed during a 30‐min interaction. Both children and mothers exhibited stability in their own behaviours and influenced the subsequent behaviours of their partners. Additionally, a comparison of partner effects indicated that overreactive discipline more strongly predicted child's negative effect than child's negative effect predicted overreactive discipline. In contrast, although a child's negative effect predicted lax discipline, lax discipline did not predict subsequent child's negative effect. Copyright © 2010 John Wiley & Sons, Ltd.     

Self-Efficacy as a Mediator of the Relationship Between Causal Attributions and Exercise Behavior

The primary purposes of this study were to examine whether the attribution–intention link was mediated by self-efficacy and whether the attribution–behavior link was mediated by self-efficacy. As a secondary purpose, we examined whether the attribution–behavior link was mediated by exercise intentions. These relationships were tested prospectively at multiple time points. Participants were 260 adult exercisers ( M age=32 years) enrolled in 12 weeks of structured exercise classes. Social cognitive measures were assessed at early and midprogram; attendance was tracked for the first and second half of the program. Hierarchical multiple regression procedures indicated support for self-efficacy as a mediator of the relationship between attributions and behavior. Secondary analyses revealed support for intention as a mediator of the attribution–behavior relationship. Finally, additive relationships in support of social cognitive theory also were detected. The attribution/self-efficacy/behavior link is important for adherence interventions and should be investigated further in both asymptomatic and symptomatic populations.     

Co‐thought gestures in children's mental problem solving: Prevalence and effects on subsequent performance

Co‐thought gestures are understudied as compared to co‐speech gestures yet, may provide insight into cognitive functions of gestures that are independent of speech processes. A recent study with adults showed that co‐thought gesticulation occurred spontaneously during mental preparation of problem solving. Moreover, co‐thought gesturing (either spontaneous or instructed) during mental preparation was effective for subsequent solving of the Tower of Hanoi under conditions of high cognitive load (i.e., when visual working memory capacity was limited and when the task was more difficult). In this preregistered study ( https://osf.io/dreks/ ), we investigated whether co‐thought gestures would also spontaneously occur and would aid problem‐solving processes in children (N = 74; 8–12 years old) under high load conditions. Although children also spontaneously used co‐thought gestures during mental problem solving, this did not aid their subsequent performance when physically solving the problem. If these null results are on track, co‐thought gesture effects may be different in adults and children.     

Measuring motor speed through typing: a surrogate for the finger tapping test

Motor speed is an important indicator and predictor of both cognitive and physical function. One common assessment of motor speed is the finger-tapping test (FTT), which is typically administered as part of a neurological or neuropsychological assessment. However, the FTT suffers from several limitations, including infrequent in-person administration, the need for a trained assessor and dedicated equipment, and potential short-term sensory–motor fatigue. In this article, we propose an alternative method of measuring motor speed, with face validity to the FTT, that addresses these limitations by measuring the interkeystroke intervals (IKI) of familiar and repeated login data collected in the home during a subject’s regular computer use. We show significant correlations between the mean tapping speeds from the FTT and the median IKIs of the nondominant (r = .77) and dominant (r = .70) hands, respectively, in an elderly cohort of subjects living independently. Finally, we discuss how the proposed method for measuring motor speed fits well into the framework of unobtrusive and continuous in-home assessment.     

Early educational foundations for the development of civic responsibility: an African experience

An innovative curriculum designed to foster the development of social responsibility among pre-adolescent children was introduced at a rural Zambian primary school. The curriculum invoked Child-to-Child principles focusing on health education, advancing a synthesis of Western psychological theories and African cultural traditions. The teacher sought to democratize the educational process through cooperative learning in mixed-gender, mixed-social-class, and mixed-ability study groups. Learners engaged in community service activities and contributed to the nurturant care of younger children. Young adults interviewed seventeen years after completing the program recalled their experience and reflected on how it had promoted their personal agency, cooperative disposition, and civic responsibility in early adulthood.     

Concurrent validity of the wide range assessment of visual motor abilities in typically developing children ages 4 to 11 years

Pediatric clinicians working with school-age children use the Wide Range Assessment of Visual Motor Abilities (WRAVMA) as a method for evaluating visual perception and motor skills in children despite limited information on concurrent validity. Whether it may be substituted for the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI) and has suitable estimates of concurrent validity were examined with a convenience sample of 91 typically developing children ages 4 to 11 years. No systematic concurrent validity between the WRAVMA and the VMI emerged. Only two subtests of the WRAVMA (Matching with Visual Perception, and Pegboard with Motor Coordination) gave scores statistically significantly correlated with those on the VMI, and these correlations were weak, accounting for very small amounts of the shared variance. As such, they have low clinical relevance. These findings do not provide evidence of concurrent validity to support the use of WRAVMA as an alternative method for the VMI for assessing children's visual perception and motor skills.
