Stimulus and response contributions to the children's reaction-time repetition effect

Adults and 8-, 10-, 12-, and 14-year olds completed a serial reaction-time task with two stimuli mapped to each of two responses and 100-, 500-, and 1000-msec response-stimulus intervals (RSIs). Trials were classified as (1) identical (same stimulus and same response on two consecutive trials), (2) response equivalent (different stimulus but same response on two consecutive trials), or (3) different (different stimulus and different response on two consecutive trials). Identical and different trials were compared as a general indication of repetition effects. Response-equivalent minus identical reaction time identified stimulus contributions, and different minus response-equivalent reaction time identified response contributions. Adults received a repetition advantage at all RSIs and children received a repetition advantage at 500- and 1000- but not 100-msec RSIs. Stimulus contributions accounted for the repetition effect for both adults and children. At the 500- and 1000-msec RSIs, both the overall repetition effect and stimulus contribution were positive and decreased in magnitude as age increased. The response contribution was independent of RSI and was negative for 8- and 10-year-olds and near zero or positive for older performers. At the longer RSIs, positive stimulus contributions were sufficient to overcome the negative response contributions present for younger children.     

Incidence of suicidal ideation and behavior in the United States, 1994.

Completed suicides reflect only a portion of the impact of suicidal behavior; sublethal behaviors cause morbidity and can signal treatable problems such as depression. There is no national quantification of nonlethal suicidal behaviors. The present study used a random-digit-dialed telephone survey to estimate the 12-month incidence of suicidal ideation, planning, and attempts among U.S. adults. Of 5,238 respondents, 5.6% (representing about 10.5 million persons) reported suicidal ideation, 2.7% (about 2.7 million) made a specific suicide plan, and 0.7% (about 700,000) made a suicide attempt (estimate = 1.1 million attempts). Hence, suicidal behaviors are not uncommon and occur along a continuum ranging from ideation to completed suicides. Preventing nonlethal precursor behaviors may prevent deaths.     

Changes in social support as mediators of the impact of a psychosocial intervention for spouse caregivers of persons with Alzheimer's disease

The spouse caregivers of 406 patients with Alzheimer's disease were randomly assigned to an enhanced counseling and support intervention or to a usual care control condition. Structured interviews were conducted to assess changes in social support and psychosocial outcomes for the 312 caregivers who provided care in the home for at least 1 year. The number of support persons, satisfaction with the support network, and support persons' assistance with caregiving all increased significantly as a function of the intervention. Structural equation models indicated increased satisfaction with the social support network mediated a significant proportion of the intervention's impact on caregiver depression. A portion of this mediated effect was further mediated by changes in caregiver stress appraisals. Implications for strengthening intervention programs for spouse caregivers of individuals with Alzheimer's disease are discussed.     

There is no moral authority in medicine: response to Cowdin and Tuohey.

Central to the Cowdin-Tuohey paper is the concept of a moral authority proper to medical practitioners. Much as I agree with the authors in refusing to degrade doctors to the status of mere technicians, I argue that one does not succeed in retrieving the moral dimension of medical practice by investing doctors with moral authority. I show that none of the cases brought forth by Cowdin-Tuohey really amounts to a case of moral authority. Then I try to explain why no such cases can be found. Developing an insight that is common to all the major moral thinkers in the philosophia perennis, I show that doctors are professionally competent with respect only to a part of the human good; morally wise persons are competent with respect to that which makes man good as man. I try to show why it follows that a) professional expertise has no natural tendency to pass over into moral understanding, and that b) doctor and non-doctor alike start from the same point in developing their understanding of medical morality. It follows that the authors fail in their attempt to de-center the moral magisterium of the Church by setting up centers of moral authority outside of the Church.     

Closeness between female college students and their professors: A novel assessment technique

An empirical investigation was conducted using a technique developed by Adler to assess how close female college students felt toward their professors. The sample included mostly white college women enrolled in a psychology of women course. The women felt closer to their female professors than to their male professors. The findings have pedagogical implications.We would like to thank Susan Eckstein, Maria Narvaez, Kathleen Peets, Ann Pufall, Sue Rosenberg Zalk, and two anonymous reviewers for their help.     

Attitudes of clinical psychologists towards clients with personality disorders

Previous studies have found that a variety of mental health professionals hold negative attitudes towards clients diagnosed with a personality disorder. These negative attitudes may lead to clients receiving a lower quality of service. Specialist training has been found to improve attitudes towards personality disorders but no empirical studies in Australia have examined this among clinical psychologists. In this study, the attitudes of 81 clinical psychologists towards clients with personality disorders were examined. We were specifically interested in investigating the relationship between recency of specialist training and clinician's attitudes as well as the influence of percentage of personality disorder clients on the clinician's caseload. Results demonstrated that both recency of specialist training and percentage of clients seen were associated with more positive attitudes; however, a higher caseload of clients with personality disorders was the most important predictor of positive attitudes. The implication is that recent participation in specialist training for personality disorders appears to be valuable in improving clinician's attitudes but that more positive attitudes are associated with seeing a greater number of individuals with personality disorders.     

Moderators of the association between exercise identity and obligatory exercise among participants of an athletic event

Previous research has connected exercise identity with obligatory exercise, yet to date no empirical studies have identified moderator variables of this association. The current study included participants of an athletic event (full marathon, n = 582; half marathon, n = 1,106; shorter distance, n = 733) who completed questionnaires about exercise behaviors, obligatory exercise, and internalization of both the thin-ideal and athletic-ideal body shapes. General linear model analyses were conducted to examine the exercise identity–obligatory exercise relationship; moderator variables included gender, internalization of the thin-ideal body shape, and internalization of the athletic-ideal body shape. After controlling for the effects of body mass index, age, and distance group, the three-way interaction of exercise identity, gender, and internalization of the athletic-ideal body shape predicted obligatory exercise. Findings suggest that women who report high identification with exercise and high value on having an athletic physique may be vulnerable to obligatory exercise.     

Factor structure of the Eating Disorder Examination Questionnaire (EDE-Q) in male and female college athletes

The study explored the psychometric properties of the Eating Disorder Examination Questionnaire (EDE-Q) among 1637 university students. Participants were divided into male (n = 432) and female (n = 544) competitive athletes, and male (n = 229) and female (n = 429) comparison groups comprised of individuals who had not engaged in competitive sports for at least one year. All groups were subjected to confirmatory factor analysis (CFA) to test the fit of the published factor structure in this population, and then exploratory FA (EFA). A three-factor solution was the best fit for three out of four groups, with a two-factor solution providing best fit for the male comparison group. The first factor for all groups resembled a combined Shape and Weight Concern subscale. The factor structure among male and female competitive athletes was remarkably similar; however, non-competitive athletic/low activity males appear qualitatively different from other groups.     

Use of an Antecedent Intervention to Decrease Vocal Stereotypy of a Student With Autism in the General Education Classroom

This study examined the use of an antecedent-based intervention to reduce the vocal stereotypy of a student diagnosed with Autism within the general education classroom. The student displayed frequent nonfunctional speech and disruptive vocal sounds. An antecedent-based intervention, involving the use of qualitatively different cards—to cue the student when it was appropriate or inappropriate to engage in vocal stereotypy—was designed and implemented. An adaptive alternating treatment design was utilized and conditions were randomized and counterbalanced across treatment sessions. Data on vocal stereotypy were collected using partial interval recording. The results indicated the participant was successful in discriminating between cues and decreased stereotypy during intervention compared to baseline conditions. Similar findings were found when the intervention was implemented across a second school setting.
