Cardiovascular reactivity and interpersonal influence: active coping in a social context

Previous studies have demonstrated that effortful attempts to secure positive outcomes or avoid negative outcomes produce significant increases in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Although these effects of active coping on cardiovascular reactivity are central in current psychosomatic theories, virtually all of the research to date has used impersonal, asocial tasks. Our two studies examined the cardiovascular effects of effortful attempts to influence other people. In Study 1, male subjects attempting to influence the opinions of their discussion partner to improve their own chances of winning money displayed significantly greater SBP, DBP, and HR reactivity. In Study 2, we obtained similar effects on SBP and DBP reactivity in men and women, while both preparing an influence attempt and making that attempt. Furthermore, reactivity levels were larger as the magnitude of incentive for successful persuasion increased. Implications of this interpersonal equivalent of active coping for the development of cardiovascular disease are discussed.     

Perceptions of control, competence, and contingency as influences on the stress-behavior symptom relation in school-age children

Analyzed data from 154 school-age children and their mothers to examine the relations between stress, perceived competence and contingency, and behavior symptoms. Analyses focused on the relative merits of unidimensional vs multidimensional measures of control in predicting symptoms. The stress of undesirable life events and behavior symptoms were related in the expected direction. Multiple regression models with R2 ranging from .11 to .14 (all ps less than .0002) included significant main effects for stress, competence, and control. Analyses supported the relative superiority of the multidimensional measure of control. Models containing main effects and interaction terms were of equivalent magnitudes in accounting for variance in symptom scores. Findings support the idea of perceived control as a moderator of the stress-illness relation and are consistent with earlier suggestions that simple main effects models may be the most useful in examining these relations.     

Delusions and hallucinations as a reflection of the subcultural milieu among psychotic patients of the 1930s and 1980s

Delusions and hallucinations reported in the social histories of 150 patients admitted to an East Texas state hospital during the 1930s and of 150 patients admitted during the 1980s were examined for content that would characterize and contrast the patient subcultural milieu of the two time periods. Patients admitted during the 1930s tended to reflect the material deprivation and personal powerlessness of the great depression in delusions of great wealth and positive "special powers." The hallucinatory visions and voices of the 1980s patients reflected a more threatening and negative subcultural milieu, with more visions of blood, snakes, and dead people or animals. Command hallucinations to hurt, to kill, or to do "perverse things" would also suggest that the subculture milieu of the 1980s had become more dangerous.     

Psychometric properties of Loevinger's Sentence Completion Test in an adult psychiatric outpatient sample

Little research has been conducted on Loevinger's Washington University Sentence Completion Test of Ego Development in adult psychiatric outpatients. The measure is a promising method of assessing a construct of personality and character functioning that should be useful in research on psychopathology and in choosing treatment modalities. The data presented in this study address the question of the psychometric adequacy of the measure in this segment of the subject population. Specifically, estimates of interrater reliability, internal consistency, and test-retest reliability are presented for a sample of 42 adult outpatients. In addition, the relationship between total protocol ratings and item sum scores is explored.     

A quantitative analysis of chain-schedule performance

Six pigeons were trained with a chain variable-interval variable-interval schedule on the left key and with reinforcers available on the right key on a single variable-interval schedule arranged concurrently with both links of the chain. All three schedules were separately and systematically varied over a wide range of mean intervals. During these manipulations, the obtained reinforcer rates on constant arranged schedules also frequently changed systematically. Increasing reinforcer rates in Link 2 of the chain increased response rates in both links and decreased response rates in the variable-interval schedule concurrently available with Link 2. Increasing Link-1 reinforcer rates increased Link-1 response rates and decreased Link-2 response rates. Increasing reinforcer rates on the right-key schedule decreased response rates in Link 1 of the chain but did not affect the rate in Link 2. The results extend and amplify previous analyses of chain-schedule performance and help define the effects that a quantitative model must describe. However, the complexity of the results, and the fact that constant arranged reinforcer schedules did not necessarily lead to constant obtained reinforcer rates, precluded a quantitative analysis.     

Autobiographical memory in a case of multiple personality disorder

Previous research on multiple personality disorder (MPD) has been concerned with between-personalities amnesia, and little attention has been paid to within-personality memory function. This study examined the autobiographical memory of a multiple personality patient, I.C., with cueing procedures that have proven useful in previous studies of normal and abnormal memory. Results indicated that I.C. was able to retrieve autobiographical episodes from the recent past, although her performance differed in several respects from that of matched controls. The study also revealed a striking deficit in I.C.'s autobiographical memory for childhood: She was unable to recall a single episode from prior to the age of 10 in response to various retrieval cues, whereas control subjects had no difficulty recalling numerous childhood episodes. This phenomenon of extended childhood amnesia has not been reported previously in studies of MPD.     

Agreeable fancy or disagreeable truth? Reconciling self-enhancement and self-verification

Three studies asked why people sometimes seek positive feedback (self-enhance) and sometimes seek subjectively accurate feedback (self-verify). Consistent with self-enhancement theory, people with low self-esteem as well as those with high self-esteem indicated that they preferred feedback pertaining to their positive rather than negative self-views. Consistent with self-verification theory, the very people who sought favorable feedback pertaining to their positive self-conceptions sought unfavorable feedback pertaining to their negative self-views, regardless of their level of global self-esteem. Apparently, although all people prefer to seek feedback regarding their positive self-views, when they seek feedback regarding their negative self-views, they seek unfavorable feedback. Whether people self-enhance or self-verify thus seems to be determined by the positivity of the relevant self-conceptions rather than their level of self-esteem or the type of person they are.     

Effects of Salience of Consciousness-Raising Information on Perceptions of Acquaintance versus Stranger Rape

In the present study the effects of salience of consciousness-raising information on the perception of acquaintance vs. stranger rape were focused on. One half of the subjects were exposed to information which emphasized the inappropriateness of sexual inequality (salient condition), while the other half were exposed to no such information (nonsalient condition). Subsequently, subjects read a passage which depicted an acquaintance rape or a stranger rape. The results indicated that those subjects in the salient condition perceived the victim more favorable and reported a lesser likelihood to commit rape (male subjects) than those in the nonsalient condition. Additionally, those in the stranger rape condition perceived the victim more favorably and reported a lesser likelihood of committing rape (male subjects) than those in the acquaintance rape condition. Finally, there was a significant interaction between salience and type of rape. To amplify, when subjects read the stranger rape passage, perceptions did not vary as a function of salience. On the other hand, when subjects read the acquaintance rape passage, those in the salient condition perceived the victim more favoraby and reported a lesser likelihood of committing rape than those in the nonsalient condition.
