Individual differences in pulse brightness perception

When brightness-pulse duration relations are studied with a simultaneous brightness discrimination procedure, three classes of observers emerge (Bowen & Markell, 1980). These classes are defined by whether or not observers perceive temporal brightness enhancement (the Broca-Sulzer effect) under two asynchrony conditions for pulses to be compared: simultaneous onset and simultaneous offset. Type A observers perceive brightness enhancement for both asynchrony conditions; Type B observers perceive brightness enhancement for simultaneous offset of pulses but not for simultaneous onset; Type C observers do not generate the Broca-Sulzer effect under either asynchrony condition. Here we present supplementary measures on observers of all three types: (1) magnitude estimation of the brightness of single pulses of light of varying duration, (2) modulation sensitivity for sin~wave flicker, and (3) contrast sensitivity for moving sine-wave gratings. The magnitude estimation data differentiated the three types of observers, but flicker and motion sensitivity did not. The three classes of observers probably differ in the perceptual criteria they employ in judging the brightness of isolated pulses of light; they probably do not differ in their underlying neurophysiological responses.     

Intergenerational occupational inheritance in the military: a reexamination

Recent problems the military services have experienced in retaining sufficient personnel to meet growing manpower requirements are unlikely to diminish in the 1980s. As a consequence, it is vital that military decision makers understand the factors that influence career commitments of service members. Based on a stratified probability sample of Air Force married enlisted personnel and officers, this study reexamines the relationship between the military service patterns of fathers and the career intentions of their sons who enlist in military service. It also expands upon past analysis to include the actual career decisions of military men as a dependent variable. In partial support of past research, the present investigation provides no support for an intergenerational linkage between military service patterns of fathers and the career intentions and decisions of their sons--either enlisted members or officers. Implications for future research are discussed.     

Effects of Counseling and Ethnic Identity on Perceived Risk and Cancer Worry in African American Women

Improving breast screening behaviors in African American women is an important public health goal. To increase participation in screening, it is necessary to identify factors that contribute to reduced screening, including perceived risk and cancer worry. This paper presents predictors of changes perceived in risk and worry among African American women of differing ethnic identities as they undergo breast cancer risk counseling. Participants (n = 113) were recruited from community sources to a study of counseling for breast cancer risk. They completed a baseline assessment, randomly received breast cancer risk counseling or served as a control group, and completed a follow-up assessment. Counseling produced significant differences in perceived risk and cancer worry. Predictors of risk and worry changes, as a result of counseling, included income and ethnic identity. These data can guide better services for African American women and research into the complexity of the effects of ethnic identity on health.     

THE EFFECTS OF THE QUESTION “WHAT DO YOU WANT?” ON MAND TRAINING OUTCOMES OF CHILDREN WITH AUTISM

Mands sometimes are taught using the question “What do you want?” as a supplement to the required features of the mand relation: an establishing operation and a related consequence. Although verbal prompts have been used during mand training, they also may result in undesirable stimulus control. However, no direct empirical evidence exists to support this concern. The purpose of the present study was to compare mand training with and without supplemental questions on acquisition rate and maintenance when those questions were no longer presented. The 2 training conditions did not differ substantially in their outcomes for 2 children with autism.     

Partner violence against heterosexual and gay men: Prevalence and correlates

Female victims of intimate partner violence (IPV) have been the focus of a substantial amount of research. However, the subject of male victims of IPV remains a controversial topic, and one which has been comparatively neglected within the literature, despite some findings suggesting that men are victimized by intimate partners at an equivalent, or even higher rate than women. This paper reviews the literature on male victims of IPV, both within opposite and same-gender relationships, focusing on the prevalence and correlates of IPV, as well as exploring the relationship between IPV and ethnicity. According to the literature reviewed, the prevalence of female perpetrated IPV against heterosexual male victims ranges from 0.2% to 93%, homosexual male victimization ranges between 1.8% and 93.7%, and heterosexual female victimization ranges between 1.3% and 86% depending on the type of IPV included, whether the reference period includes the past 12 months, or lifetime experience, and the method used to assess IPV. These data indicate that victimization is as much an issue for men as it is for women. In addition, it appears that men of certain ethnicities may be more at risk than others. Finally, the empirical literature which examines the correlates of male victimization indicates that male victims in heterosexual and gay relationships share many correlates. Unfortunately however, methodological weaknesses in the available literature and a lack of research in some areas restrict the extent to which conclusions can be drawn, and findings generalized. Recommendations for future research are made.     

Emotional support and counselling for people with visual impairment: Quantitative findings from a mixed methods pilot study

Aims: This paper reports on mainly quantitative findings from a mixed methods evaluation of a new model of emotional support and counselling for people with moderate visual impairment. Method: The CORE Outcome Measure was completed with service users at baseline and post‐intervention to assess the impact of the new service on psychological wellbeing and social functioning. Their perceived needs and expectations of the service were also explored. Results: Of the 35 individuals providing data at each assessment time, mean item scores on the CORE fell significantly (p<.001), taking the sample from within a clinical population before therapy, to a mean score below this following therapy. A more positive outlook accompanied this improvement in functioning. Discussion: Findings from the study augment the growing evidence that emotional support and counselling services can play an important role alongside and within related vision services. Implications for practice: The study indicates that therapeutic input for the visually impaired client group may need to target both wellbeing (feelings about oneself and the future) and problems (depression, anxiety, physical health, and trauma). Conclusions: Our findings suggest that a dual model of emotional support and counselling offers considerable benefit for people with visual impairment.

Managing personal networks: An examination of how high self-monitors achieve better job performance

Structural holes are important network structures that have positive implications for individuals' job performance. Although the emergence of structural holes is closely related to self-monitoring, little is known about how chameleon-like high self-monitors manage to occupy brokerage positions. We posited that leader–member exchange (LMX) quality and network diversity might serve as two important mediating paths through which self-monitoring links to structural holes and sequential job performance. Using structural equation modelling to analyse 10 department networks, we found that high self-monitors were more likely to build high-quality LMX relationships and diversified co-worker networks, which helped to enhance structural holes and job performance. Theoretical contributions and managerial implications are discussed.
