High school polydrug users and abusers

Among 433 high school seniors, 12% were determined to be either polydrug users or abusers. In comparison to the non-polydrug users, polydrug users and abusers were significantly more likely to indicate: (1) physical abuse by and many conflicts with parents; (2) self-ratings of lazy, bored, rejected, and unhealthy, (3) serious suicidal thoughts, delinquent behavior, early use of marijuana and alcohol, and the tendency to drink more than six alcoholic drinks at a sitting; and (4) agreement with the following statements: "If something feels good, I usually do it and don't worry about the consequences" and "I try to play as much as possible and work as little as possible." These findings suggest that many polydrug users and abusers are either seeking pleasure or trying to escape pain. Because of the different reasons behind polydrug use, a variety of treatment and prevention strategies will be necessary to curb the polydrug problem among adolescents.     

Psychophysiologic correlates of Type A behavior: Comments on Houston (1983) and Holmes (1983)

On the basis of a literature review, B. K. Houston (1983, Journal of Research in Personality, 17, 22–39) concluded that there is a reliable but relatively weak association between Type A (coronary-prone) behavior and heightened physiologic reactivity. D. S. Holmes (1983, Journal of Research in Personality, 17, 40–47) contends that by failing to take into account dependent measures yielding null results, Houston overestimated the consistency with which A/B differences have been obtained. In the present article, we show that it is critical to take into account the method used to assess Type A behavior. Structured Interview assessments show a more consistent association with reactivity than those based on the Jenkins Activity Survey. We then point out that, for certain physiologic measures, null effects do not necessarily reflect an absence of A/B differences in sympathetic-adrenomedullary activity. Other issues that are discussed include the role of situational parameters in eliciting hyperresponsiveness in Type A's, the problem of evaluating the magnitude and importance of A/B effects, and the need for a more theoretical approach to the study of Type A behavior.     

Apparent velocity of motion aftereffects in central and peripheral vision

Adapting to a drifting grating (temporal frequency 4 Hz, contrast 0.4) in the periphery gave rise to a motion aftereffect (MAE) when the grating was stopped. A standard unadapted foveal grating was matched to the apparent velocity of the MAE, and the matching velocity was approximately constant regardless of the visual field position and spatial frequency of the adapting grating. On the other hand, when the MAE was measured by nulling with real motion of the test grating, nulling velocity was found to increase with eccentricity. The nulling velocity was constant when scaled to compensate for changes in the spatial 'grain' of the visual field. Thus apparent velocity of MAE is constant across the visual field, but requires a greater velocity of real motion to cancel it in the periphery. This confirms that the mechanism underlying MAE is spatially-scaled with eccentricity, but temporally homogeneous. A further indication of temporal homogeneity is that when MAE is tracked, by matching or by nulling, the time course of temporal decay of the aftereffect is similar for central and for peripheral stimuli.     

ATTRIBUTIONS,COMPLEXITÉ ATTRIBUTIONNELLE ET SATISFACTION CONJUGALE*

The present study investigates the relation among attributions, attributional complexity, and marital satisfaction. More specifically, we examine the value of attributional complexity as a possible moderator in the relationship between attributions and marital satisfaction. Seventy-four French Canadian couples completed the Marital Attributional Style Questionnaire, the Conflict Rating Scale, the Attributional Complexity Scale, and the Dyadic Adjustement Scale. The results corroborate the existence of a relationship between attributions and marital satisfaction. Against predictions, attributional complexity does not seem to moderate the relation between attributional style and marital satisfaction. The theoretical implications of these findings are discussed.     

Task demand and cardiovascular response magnitude: further evidence of the mediating role of success importance

The interactive effects of success importance and task demand upon cardiovascular reactivity were investigated in 2 experiments. In Experiment 1, Ss learned that success on an easy or difficult memory task would allow them to avoid a mild or severe noise. As expected, pretask and task elevations in heart rate and systolic blood pressure increased with difficulty only when the noise was to be severe. In Experiment 2, Ss listened to a victim, attending either to how she must feel or to technical features of the presentation. Then they were given the chance to earn a donation by succeeding on an easy or difficult memory task. Pretask cardiovascular data accorded with predictions predicated on the assumption that the need to help would be greater among victim perspective Ss. For them, systolic elevations increased with difficulty, whereas for technical perspective Ss systolic elevations were low regardless of task demand.     

Introduction

I would also like to extend my special thanks to my co-editor for this special section, Dr. Nancy Edwards. Her sensible editorial judgment, emotional support, and intellectual lucidity were crucial in bringing this project to fruition.     

Variables related to pro-choice attitudes among undergraduates

Pro-choice attitudes among undergraduates were assessed to determine the extent of anti-abortion sentiments during President Reagan's first term in office, which was marked by his support of the anti-abortion issue as well as by increased media coverage of the right-to-life movement. Self-administered questionnaires were completed by 840 participants enrolled in introductory psychology classes at a university in central Texas during the week prior to the presidential election of 1984. Students were asked if they would approve or disapprove of abortion under four different circumstances. Results indicated that the majority of both males and females were in favor of allowing abortion under all four conditions.     

Motivation, anxiety, and the difficulty of avoidant control

The present research addresses the question of whether avoidant control that is difficult to exercise induces greater physiologic arousal and unpleasant affect than easy-avoidant control or no-avoidant control. Two types of control difficulty were distinguished and factorially varied: (a) control difficulty due to the effortfulness of a controlling activity and (b) control difficulty due to uncertainty about how to exercise control over an unpleasant outcome. To examine responses under conditions where avoiding an unpleasant event is impossible, a cell was included in which subjects were not given the means by which to exercise control. In all but one condition (the high-effort-exercise/high-response-uncertainty condition), when avoidance was expected to be easy or impossible (a) pulse rates were lower, (b) digital pulse volumes were higher (indicating reduced physiologic activity), (c) self-reported anxiety was lower, and (d) ratings of the stressor's unpleasantness were lower than they were when avoidance was expected to be difficult. In the high-effort-exercise/high-response-uncertainty condition, cardiovascular arousal, self-reported anxiety, and shock unpleasantness scores were relatively low, suggesting that control was sufficiently difficult in that condition to cause subjects to "give up." Results are discussed in terms of a recently proposed model of motivation, conceptions of anxiety, and the relation between stress and control.     

Listeners' discrimination of real and human-imitated animal sounds

To determine if listeners can accurately distinguish between real and human-imitated animal sounds, a total of 165 recorded sounds (55 real and 110 human-imitated) of cats, cows, dogs, pigs, and sheep were randomly arranged on a master tape and presented to 30 listeners for discriminative judgments. Results indicate that, in general, listeners can accurately discriminate real from human-imitated animal sounds. Suggestions for future research are discussed.     

The impact of task difficulty upon perceptions of arousal and goal attractiveness in an avoidance paradigm

Measures of goal attractiveness, self-perceived energization, and self-perceived tension were taken immediately before 55 young male subjects were to perform an easy, difficult, or impossible motor activity in order to avoid an unpleasant noise. Results showed a greater magnitude of goal valence, and higher energization and tension in the difficult task condition than in the easy task condition. Subjects in the impossible task condition reported reduced energy relative to subjects in the difficult task conditions; however, tension and goal attractiveness scores did not differ significantly between these conditions. Theoretical implications are discussed.
