On the form and universality of the contempt expression: A challenge to Ekman and Friesen's claim of discovery

The claim of Ekman and Friesen (1986, A New Pan- Cultural Facial Expression of Emotion,Motivation and Emotion, 10, 159–168) that they have found the first empirical support for the existence of a pancultural expression of contempt is challenged on three grounds. First, the claim that no one else had ever attempted to describe an expression unique to contempt in any culture neglects a tradition of research dating back to Darwin. Second, the data presented by Ekman and Friesen were derived using stimuli that are ambiguous representations of their intended expressions. Finally, there are earlier data for the universality of contempt expressions. Ekman and Friesen's contempt expression may best be viewed as a learned modification of a prototypical expression evolved from the infrahuman snarl.     

Children by choice or by chance: The perceived effects of parity

In a study examining inferences made about couples based on their choice whether or not to have children, college undergraduates projected 1-year and 25-year life situations for a hypothetical couple who either (1) neither had nor wished to have children, (2) were presented without any reference to children, or (3) already had two children. This manipulation notwithstanding, most couples were projected as becoming parents. Female subjects saw having children as enhancing the quality of life of both partners, while males took the opposite view.     

Treating nailbiting: a comparative analysis of mild aversion and competing response therapies.

This study compared two methods of treating nail-biting. One method involved the use of a mild aversive stimulus in which subjects painted a bitter substance on their nails, and the other required the subject to perform a competing response whenever they had the urge to bite or found themselves biting their nails. Both methods included self-monitoring of the behaviour, and a third group of subjects performed self-monitoring alone as a control condition. The study lasted four weeks. Twenty-one subjects, seven per group, participated. Both methods resulted in significant improvements in nail length, with the competing response method showing the most beneficial effect. There was no significant improvement for the control group. The competing response condition also yielded significant improvements along other dimensions such as degree of skin damage and subjects own ratings of their control over their habit. These were not seen for the other two conditions. The benefits of this abridged version of Azrin and Nunn's (Behaviour Research and Therapy, 11, 619-628, 1973) habit reversal method in terms of treatment success, use of therapist time and client satisfaction, are discussed.     

An advocacy intervention program for women with abusive partners: Initial evaluation

Experimentally tested the hypotheses that (1) battered women are in need of numerous community resources upon exit from a domestic violence shelter, (2) working with advocates increases women's effectiveness in obtaining needed resources and social support, and (3) success in obtaining resources and social support increases women's levels of life satisfaction and decreases their risk of further abuse. The initial findings of a short-term intervention project designed to provide postshelter advocacy services to women with abusive partners are presented. One-hundred forty-one battered women were interviewed immediately upon their exit from a domestic violence shelter as well as 10 weeks thereafter. Half the sample was randomly assigned to receive the services of trained advocates who assisted them in accessing needed community resources. Women who worked with advocates reported being more effective in accessing resources and had higher levels of social support and overall quality of life postintervention. Although all women reported some decrease in postshelter abuse, there were no differences between those with and those without advocates, and abuse continued to be a problem for many women.     

Effect of sulpiride on amphetamine-induced activity and stereotyped locomotion

To investigate the hypothesis that sulpiride potentiates stereotyped locomotion at an intermediate dose of amphetamine, rats were assigned to one of four treatment groups (n=7 per group): vehicle + saline; 20 mg/kg sulpiride + saline; vehicle + 3.5mg/kg amphetamine; 20 mg/kg sulpiride + 3.5 mg/kg amphetamine. An automated tracking system was used to record distance moved and sequences of movements between quadrants in a circular open-field. The results showed that amphetamine increased horizontal distance moved, and increased the number and proportion of thigmotaxic trips around the perimeter of the apparatus. Sulpiride reduced amphetamine-induced hyperactivity and the number of perimeter trips, but had no effect on the proportion and maximum run length of perimeter trips. Thus sulpiride reduces the hyperactivity produced by an intermediate dose of amphetamine, but does not appear to affect the stereotyped nature of locomotion under the drug.     

Assessing retirement satisfaction and perceptions of retirement experiences.

A 2-part investigation developed a measure of retirement as a life transition. Study 1 generated items from interviews with retirees (n = 40) and service providers. Item analysis with recent retirees (n = 86) produced a 51-item Retirement Satisfaction Inventory assessing 6 areas: preretirement work functioning, adjustment and change, reasons for retirement, satisfaction with life in retirement, current sources of enjoyment, and leisure and physical activities. Study 2 examined a heterogeneous sample of men (n = 159) and women (n = 243) retires. Factor analyses produced internally consistent subscales. Moderate, but acceptable, test-retest reliability was demonstrated. Satisfaction scores correlated with concurrent measures and, together with pre- and postretirement experiences, discriminated 4 groups of voluntary and involuntary retirees. Few effects related to gender, socioeconomic status, length of retirement, and part-time employment were found.     

Relating a Social Influence Model to the Role of Acculturation in Substance Use Among Latino Adolescents1

This study examined determinants of substance use derived from the theory of planned behavior as influenced by acculturation. Latino adolescents (n= 448) completed measures of attitudes, subjective norms, perceived behavioral control, intentions toward substance use, and 2 acculturation components. The degree to which Latino adolescents were exposed to as well as use Spanish was unrelated to determinants of future substance use, whereas the degree to which they interact with non-Latino peers exerted a protective effect regarding future substance use. However, both acculturation components influenced the extent social influence determinants predicted future substance use. Intervention strategies may need to consider acculturation in order to effectively direct resources toward those psychosocial determinants of substance use of greatest relevance to Latino populations.
