Ordered preference differences without ordered preferences

Axiomatizations of ordered preference differences typically assume that preferences are ordered. However, the mere assumption that preference differences can be ordered says nothing about whether preferences themselves are ordered. Utility representations for ordered differences without ordered preferences are investigated.     

Quality-of-life measures: hospital interview versus home questionnaire

Measures adapted from social survey research were used to assess the quality of life of 33 end-stage renal disease (ESRD) patients in a 2-week test-retest design that varied both location and format of administration (hospital interview vs. home self-administered questionnaire). The measures were found to have substantial consistency over time, location, and format. These results indicate that quality of life is a stable construct and support the usefulness of questionnaire quality-of-life measures for evaluating medical interventions.     

Psychopathy: A psychobiological perspective

After critically examining the concept of psychopathy and reviewing the major existing theories of psychopathy in the light of a psychobiological conception of abnormal behaviour (Öhman, 1981), this paper attempts to present an integrated, psychobiological model of psychopathy. Essentially this analyses psychopathy in terms of the predisposing influences, the triggering environmental events which initiate psychopathic behaviour, and the neurophsychological mechanisms which mediate it. It is suggested that individuals who show chronic antisocial behaviour, conforming to the North American term ‘sociopath’, may demonstrate a maturational deficit but do not necessarily show a psychopathic personality disorder. The latter is said to be characterised, at a personality trait level, by high Impulsiveness and Psychopathy (Blackburn, 1982 a, b), reflecting interactive deficits in goal direction and affect. At a dynamic (state) level, a psychopathic personality disorder is said to be characterised by a lack of coping, reflecting either, in the case of the secondary psychopath, a deficit in primary appraisal, (over-perception of threat), or in the case of the primary psychopath, a deficit in secondary appraisal (low perceived control over aversive environmental events). It is further suggested that a genetic predisposition to social withdrawal and exposure to an uncontrollably aversive early environment may interact to predispose an individual to develop a psychopathic personality disorder in adulthood.     

Children and cigarettes: The effect of a model who quits

Twenty-six previous studies were reviewed which demonstrated a consistent link between children's smoking uptake and exposure at home to an actively smoking older family member. The present study included another variable: the family model of smoking cessation. The smoking practices, intentions, and attitudes of 344 children aged 10–14 in Western Australia were anonymously assessed. Those with ex-smokers but no active smokers at home resembled children who had never been exposed to a smoking family model in being less likely to smoke now or intend to in the future, having fewer smoking chums, and believing that cigarettes had more personal and social disadvantages than their peers who shared households with active smokers. This suggested that any pro-smoking modeling while the ex-smoker was active had been counteracted by modeling of quitting. Implications for intervention were discussed.     

Social reciprocity in handicapped and nonhandicapped children in a dyadic play situation

Social reciprocity behavior was compared for handicapped and nonhandicapped preschool children when they were in play situations with both handicapped and nonhandicapped partners. In a counterbalanced design, handicapped and nonhandicapped children were paired with both handicapped and nonhandicapped play partners, and the social initiation and response sequences of the dyads were observed. Types of initiation observed were friendly statements, friendly questions, mildly negative advances, and demanding statements. Friendly, ignoring, and negative responses were observed to these initiations. Handicapped and nonhandicapped children did not differ on overall number of initiations. However, they did differ on the types of initiation they made. Handicapped children asked fewer friendly questions and engaged in more demanding initiations than expected. Both groups made more initiations when paired with handicapped partners than when paired with nonhandicapped partners, but the groups did not differ on the types of initiation made to handicapped and nonhandicapped partners. The handicapped children made more ignoring and negative responses to friendly initiations than the nonhandicapped children. Behaving similarly, both groups tended to respond negatively to negative and demanding initiations.     

Psychopathology subtypes and symptom correlates among former prisoners of war

Psychopathology and symptom patterns were studied in 60 former prisoners-of-war (POWs) by administering standardized tests including the Minnesota Multiphasic Personality Inventory (MMPI), an adjustment problem checklist, and a structured clinical interview. Most POWs showed marked psychological impairment, but modal profile analysis identified two prototypic MMPI patterns, which differed in pervasiveness and type of psychopathology. Profile subtypes were defined by unique clusters of clinical symptoms and differed in confinement stress severity. The typology of symptoms argues against a homogeneous conceptualization of stress-induced disorders and suggests the need for definition of the severity and subtype of stress phenomena and individual difference factors in responding to trauma.     

Dating age and stage as correlates of adolescent sexual attitudes and behavior

Dating experiences, especially the type or stage of dating, have consistently been found to be related to premarital sexual behavior. Findings regarding the age at 1st date and sexual behavior have been less consistent. This paper examined the age at which dating began and the type of dating relationship as correlates of premarital sexual attitudes and behavior among mid-teen adolescents. The analyses were based on a sample of high school students (n=836), most of whom were between the ages of 15 and 18 when the surveys were conducted. Early dating, especially early steady dating, was related to permissive attitudes and to premarital sexual experience among both males and females. The relationship between early dating and intercourse experience was particulary strong among Mormons, a religious group which has institutionalized age 16 as the legitimate age to begin dating.     

The Novacco Anger Scale and Jenkins Activity Survey as predictors of cardiovascular reactivity

This study investigated the relationship among anger, the Type A construct, and cardiovascular reactivity. The Novacco Anger Scale and the Jenkins Activity Survey (JAS) were used to measure anger proneness and Type A characteristics, respectively. Twenty-four college males were selected from the upper and lower quintiles of the JAS distribution. During the study, the subjects were exposed to varying levels of experimentally induced challenge, while measurements were taken of heart-rate and blood-pressure changes. The results showed a modest but significant correlation between scores on the Novacco Anger Scale and the JAS. More importantly, scores on the Novacco Anger Scale correlated significantly with heart rate and systolic blood pressure under all challenge conditions, while those on the JAS were unrelated to cardiovascular excitability. These results raise questions about the usefulness of the JAS as a predictor of CHD risk. They are also consistent with the beliefs of other investigators that anger and hostility are the most important Type A behaviors in predisposing patients to coronary heart disease. Additional implications of the study are discussed.
