A test of Weiner's attribution theory inertial motivation hypothesis1

This study (N= 160 males) examined the cognitive and inertial motivation effects of overt success feedback on subjects high and low in resultant achievement motivation. The cognitive effects of overt success feedback were investigated by requesting attributions to effort, ability, luck, and task difficulty concerning performance on a digit symbol substitution task. The inertial motivation effects of overt success feedback were investigated through a transfer design. Results indicated overt success feedback to have an inertial motivation effect on performance efficiency at a subsequent verbal learning task. The results provided evidence against Weiner's (1972) attribution theory version of the inertial motivation hypothesis, and were interpreted within the general learning theory framework combined with the achievement and test anxiety models of Atkinson and Sarason. The interpretation offered considers the various experimental conditions as sources of motivation.     

Aging and mental health in the decade ahead: what psychologists need to know

Until relatively recently, most psychologists have had limited professional involvement with older adults. With the baby boomers starting to turn 65 years old in 2011, sheer numbers of older adults will continue to increase. About 1 in 5 older adults has a mental disorder, such as dementia. Their needs for mental and behavioral health services are not now adequately met, and the decade ahead will require an approximate doubling of the current level of psychologists' time with older adults. Public policy in the coming decade will face tensions between cost containment and facilitation of integrated models of care. Most older adults who access mental health services do so in primary care settings, where interdisciplinary, collaborative models of care have been found to be quite effective. To meet the needs of the aging population, psychologists need to increase awareness of competencies for geropsychology practice and knowledge regarding dementia diagnosis, screening, and services. Opportunities for psychological practice are anticipated to grow in primary care, dementia and family caregiving services, decision-making-capacity evaluation, and end-of-life care. Aging is an aspect of diversity that can be integrated into psychology education across levels of training. Policy advocacy for geropsychology clinical services, education, and research remains critical. Psychologists have much to offer an aging society.

Effects of stimulus preexposure on omission responding and omission-produced dishabituation of the human electrodermal response

As a test of Wagner's (1981) theory of habituation, three experiments examined the effects of stimulus preexposure on electrodermal responding to the absence of a stimulus and on omission-produced dishabituation. The general procedure for all experiments consisted of a preexposure phase in which one stimulus (S1) was presented 20 times, followed by a pairing phase in which S1 was followed by a second event, S2. After a number of S1-S2 pairings, S2 was omitted for one trial and was then represented following S1 on the next trial. Electrodermal activity was measured in all experiments, and in Experiments 2 and 3, a measure of expectancy of S2 in the presence of S1 was also obtained to provide a putative index of S2 priming by S1. Experiments 1 (N=48) and 2 (N=72) employed 15 S1-S2 pairings prior to S2 omission. Significant omission responding and dishabituation to S2 were obtained in both experiments. However, omission effects were not influenced by preexposure presentations of S1. Experiment 3, on the other hand, demonstrated that omission responding and dishabituation were attenuated by 20 preexposures of S1 when only 4 S1-S2 pairings were employed. In addition, Experiments 2 and 3 revealed that although expectation of S2 developed as a function of S1-S2 pairings, it too was reduced by preexposure to S1. Only Experiment 3 provided preexposure effects that are consistent with Wagner's (1981) theory.
