Primary and Secondary Control Over Age-Related Changes in Physical Appearance

Beliefs about appearance-related changes due to aging were used to test the effects of perceived control and secondary control (acceptance) in a sample of 412 young, early-middle-age, and late-middle-age college-educated adults. Mean difference in aging-related appearance control and hypotheses regarding the adaptiveness of primary and secondary control were examined. Primary control over aging-related appearance was lower in older adults and secondary control was higher. In addition, the results indicated support for the Primacy/Back-Up Model that primary perceived control is important at all levels of actual control. Those with stronger beliefs in their primary control were less distressed. Secondary control served a back-up function in that it was related to less distress only for those who had medium or lower beliefs in primary control. The implications of these findings, that primary control may be advantageous even in low-control circumstances, are discussed.

On the role of causal intervention in multiple-cue judgment: positive and negative effects on learning

Previous studies have suggested better learning when people actively intervene rather than when they passively observe the stimuli in a judgment task. In 4 experiments, the authors investigated the hypothesis that this improvement is associated with a shift from exemplar memory to cue abstraction. In a multiple-cue judgment task with continuous cues, the data replicated the improvement with intervention and participants who experimented more actively produced more accurate judgments. In a multiple-cue judgment task with binary cues, intervention produced poorer accuracy and participants who experimented more actively produced poorer judgments. These results provide no support for a representational shift but suggest that the improvement with active intervention may be limited to certain tasks and environments.     

Practice Effects in Bimanual Force Control: Does Age Matter?

ABSTRACT

The authors examined age-related differences in fine motor control during a bimanual coordination task. The task required the modulation of fingertip forces in the precision grip according to a visually presented sinusoidal antiphase pattern (force range 2–12 N; frequency 0.2 Hz). Thirty-four right-handed participants of three age groups (young, early middle-aged, and late middle-aged) practiced 30 trials of the task. Accuracy and variability of relative timing and relative forces at minima and maxima of the sine wave were analyzed for hand–hand and hand–stimulus couplings and compared between age groups. Analysis showed for relative timing and force weaker hand–hand than hand–stimulus coupling as well as lower accuracy and higher variability for minima as compared to maxima. Further, we analyzed practice effects by comparing the first and last trials and characterized the course of practice by detecting the transition of a steeper to a shallower acquisition slope for the different age groups. Late middle-aged participants demonstrated poorer performance than both other groups for all parameters. All groups improved performance to a similar amount. However, an age-related difference in acquisition strategy is visible. Late middle-aged participants seemed to have focused on improvement of force amplitude, whereas young and early middle-aged focused on timing.     

Explaining Public Attitudes towards the Integration of Muslims in British Society: The ‘Solidarity of the Religious’?

There has been growing concern in recent years about the integration of Muslims and the emergence of ‘Islamophobia’ in Britain. But there has been a lack of research into the sources of public opinion towards Muslims in British society. This article contributes to emerging research in this area by using a nationally representative survey to examine public opinion towards Muslims’ efforts to integrate into British society. It examines the relative impact of social, religious, and attitudinal variables. Religious affiliation has no impact, while greater religious salience and pro-religion attitudes on religious–secular policy issues are related to positive views of Muslims’ efforts to integrate. Women and the university-educated are more positive in their assessments. A traditionalist view of Christianity, socially authoritarian beliefs, and anti-immigrant bias are related to negative views of Muslims’ efforts to integrate. Overall, the findings lend support to the ‘solidarity of the religious’ perspective and should encourage further investigation into attitudes towards religious groups in Britain.
