Movement control and maturation in elementary-grade children.

Serial tapping by 5-, 7- and 9-yr.-old boys and girls, as measured by Fitts' Law, was recorded. 60 Ss performed a reciprocal tapping task and were assessed developmentally via hand-wrist X-rays. No significant relationship was found between the fine motor task and skeletal age. The results of the motor task suggest an improvement in movement time, with age, due to an ability to plan subsequent movements rather than simply an increase in speed of arm movement.     

Sex-role stereotypes of feminists and nonfeminists

In light of recent attempts by feminists to upgrade the status of women by stressing the positive aspects of femininity, a comparison of sex-role stereotyping by women who endorse women's liberation with those who do not was made. Feminists showed a more positive perception of women; both groups stressed positive feminine traits in describing an ideal woman, but feminists would like to see more dominance in women. Two negative stereotypes, not previously documented, emerged from this analysis: the depiction of men as cooler, more boastful, awkward, and insensitive by the feminists and women's liberationists as more boastful, excitable, and unattractive by the nonfeminists.     

Visual signal detection and the locus of foreperiod effects

The effect of alertness on S's sensitivity to external signals was determined by varying the foreperiod in a visual signal detection task. Discriminability increased with increasing foreperiods up to an optimal foreperiod, beyond which it decreased slightly. This pattern of results parallels closely that of many foreperiod studies in which reaction time was the dependent variable. Because no speeded response was required in this signal detection task, it was concluded that alertness must be affecting an information processing stage prior to those associated with responding. Other evidence indicates that alertness does not affect sensory stages either. Alertness, by elimination, must be affecting the operation of a central stage, Posner's view of alertness which implicates the central stages is discussed.     

Multiple family therapy for Chinese families of children with attention deficit hyperactivity disorder (ADHD): treatment efficacy from the children’s perspective and their subjective experiences

This paper reports the results of our study that assessed the treatment efficacy of multiple family therapy (MFT) from the perspective of participating Chinese children with attention deficit hyperactivity disorder (ADHD) and identified their subjective experiences. Forty‐three children with ADHD in the experimental group (EG) completed a forty‐two‐hour MFT, whilst forty‐five children with ADHD in the control group (CG) had attended two writing classes scheduled three months apart that were similar to those of the MFT. Data from the outcome study were gathered using standardized questionnaires and data from the qualitative study were drawn from thirteen children with ADHD who had completed the MFT and attended the focus group interviews (n = 5) or individual interviews (n = 8) conducted in the post‐treatment phase. The results of the Paired sample t‐test and MANOVA indicated no significant changes on the scores for the four measures adopted (perception of competence, hopefulness, parent‐child relationship and perceived social support) in the pre‐ and post‐treatment for the EG and the CG. Five themes emerged from the narratives of children with ADHD, which revealed the children’s subjective experiences with the MFT: (a) full of fun; (b) building friendships through common experiences; (c) a happy family time; (d) safe space; and (e) positive parental responses and communications.     

Incremental theories of weight and healthy eating behavior

We examined whether a belief in weight as malleable (an incremental theory) leads to healthier eating than a belief that weight is fixed (an entity theory). Participants with incremental theories of weight consumed fewer calories from high‐calorie foods in a lab‐based taste‐test than did those with more entity theories of weight. This pattern held correlationally, with naturally occurring theories of weight (Study 1), and when we experimentally manipulated participants’ theories of weight (Study 2). A third study provided evidence that differences in self‐efficacy regarding food mediate the relationship between theories of weight and eating behavior (Study 3). One way to encourage healthy eating might be to develop interventions that encourage more incremental views of weight.     

The Effects of Alcohol Intoxication on Accuracy and the Confidence–Accuracy Relationship in Photographic Simultaneous Line‐ups

Acute alcohol intoxication during encoding can impair subsequent identification accuracy, but results across studies have been inconsistent, with studies often finding no effect. Little is also known about how alcohol intoxication affects the identification confidence–accuracy relationship. We randomly assigned women (N = 153) to consume alcohol (dosed to achieve a 0.08% blood alcohol content) or tonic water, controlling for alcohol expectancy. Women then participated in an interactive hypothetical sexual assault scenario and, 24 hours or 7 days later, attempted to identify the assailant from a perpetrator present or a perpetrator absent simultaneous line‐up and reported their decision confidence. Overall, levels of identification accuracy were similar across the alcohol and tonic water groups. However, women who had consumed tonic water as opposed to alcohol identified the assailant with higher confidence on average. Further, calibration analyses suggested that confidence is predictive of accuracy regardless of alcohol consumption. The theoretical and applied implications of our results are discussed.© 2017 The Authors Applied Cognitive Psychology Published by John Wiley & Sons Ltd.
