Expression of interpersonal aggression by angered and nonangered persons with the type A and type B behavior patterns

Thirty-seven subjects with the Type A or the Type B behavior pattern were first either angered or not angered in a problem-solving task by a confederate who posed as another subject. In a subsequent bogus learning experiment, the Type A and Type B subjects had the opportunity to punish or reward the confederate. The effectiveness of the anger manipulation was attested to by the fact that angered subjects had reliably higher pulse rates, systolic blood pressure, and diastolic blood pressure. In the learning experiment, Type A subjects who had not been angered gave the confederate reliably higher levels of punishment than did Type B subjects, but there was not a difference in the levels of punishment given by Type A and Type B subjects who had been angered. There was not a difference between Type A and Type B subjects in the levels of reward they gave the confederate. The results provided behavioral evidence for aggression in persons with the Type A behavior pattern. The fact that the difference in aggression was limited to nonangered subjects was interpreted in terms of differences in attributions of responsibility.     

Attention to important versus trivial tasks and salience of fatigue-related symptoms for coronary prone individuals

The present study tested the hypothesis that individuals with the Type A coronary prone behavior pattern focus their attention more on important tasks, and less on trivial tasks than do Type B's. The study used a paradigm in which some subjects worked on math problems (important task) and rated intervening mood items (trivial task), whereas others rated mood items they were to memorize (important task) and worked on intervening math problems (trivial task). All subjects were later tested on recall of mood items. Results indicated that Type A's performed better on math problems and recalled more fatigue-related mood items when the task was important than when it was trivial; for Type B subjects, there was no difference in the number of math problems solved correctly or number of mood items recalled between important and trivial task conditions. Moreover, Type A's reported greater fatigue when mood recall was the important task than when math was the important task, whereas fatigue ratings of Type B's did not differ across these conditions. The findings suggest that Type A's suppress their attention to fatigue-related symptoms only when symptoms are not the objects of focus.     

Challenge seeking and the type A coronary-prone behavior pattern

The present investigation sought to further delineate the Type A coronary-prone behavior pattern and to elucidate the psychophysiological process through which this behavioral disposition is translated into heart disease. Type A and Type B male subjects engaged in tasks that required varying degrees of activity before an assessment of challenge-seeking tendencies. Type A participants sought greater degrees of challenge than did their Type B counterparts. In addition, the more active the person with Pattern A had been immediately before the challenge-seeking opportunity, the greater the degree of challenge sought. Precedent activity level did not significantly influence challenge seeking in the Type B population. The Type A subjects also had significantly faster heart rates during performance of a challenging task. Pattern A behavior may be translated into heart disease through the cumulative deleterious effects of chronic and excessive challenge-induced cardiovascular excitation.     

Type a behavior as a generally available strategy: Varying activation by tasks and instructions

Abstract

This study tested the hypothesis that the proportion of subjects resorting to Type A behavior (increased effort powered by arousal in response to a challenge) would be governed by the appropriateness of effort/arousal to the task. Sixty-nine male and female subjects classified as Type A or not-A responders by Structured Interview performed physical exercise, a vigilance task and a videogame with or without challenging instructions. For the (effort-salient) exercise, instructions produced a mean increase in arousal regardless of behavior pattern, while in the vigilance (low salience) task they produced no effect. Only in the videogame task did behavior pattern classification predict arousal in interaction with instructions. Effort, as measured by performance, showed a trend to increase with challenging instructions. Ratings by subjects of physical feelings paralleled these results, but positive, negative and emotional feelings did not show behavior pattern or instruction effects. The results support a view of Type A as a generally available response to which individuals show a differential activation rather than a character trait.     

Allocation of attention and physiological responsivity in the type A coronary-prone individual

Recent studies have suggested that persons exhibiting the Type A coronary-prone behavior pattern allocate their attention to the environment differently than those not exhibiting the pattern. The present study was done to relate such differences in cognitive responding to cardiovascular changes during a dual-focus task. Heart rate and blood pressure were monitored in Types A and B male college students while they performed a color/word conflict primary task and a reaction-time secondary task. There were no differences in the behavioral performance of the Types A and B individuals. However, Types A and B subjects differed in mean heart rate, heart-rate variability, and phasic heart-rate pattern to the reaction-time stimuli. The reaction-time paradigm appears a fruitful base from which to explore cognitive/physiological response relations for Type A and Type B individuals.     

Stress effects on affiliation preferences among subjects possessing the type A coronary-prone behavior pattern

An experiment tested the hypothesis that when subjects who display the Type A coronary-prone behavior pattern are placed under stress, they prefer to wait for the stressful event with others, but desire to work under stress alone. One half of 25 Type A and 25 Type B (non-coronary-prone) subjects were told that they would receive painful electric shock while working on a mental task, while the other one half were told that they would receive subliminal stimulation. Both groups were then given the choice of waiting for the event with others or alone and the choice of working on the task alone, in the company of others, or in a leader-directed group. The results showed that Type As relative to Type Bs tended to wait in the company of others regardless of threat level, but displayed a marked preference to work alone under high threat. This decision to work alone was not influenced by waiting preference. Subsequent correlational studies showed that coronary patients (n = 40) reported a greater preference for working alone when under pressure than matched controls (n = 40), as did Type A college students (77% vs. 14% for Type Bs) when asked their preference within the context of the structured interview that is used to assess the Type A pattern. The significance of the findings for increasing the understanding of affiliative preferences and coronary-prone behavior are discussed.     

Type A behavior, family history of hypertension, and cardiovascular responsivity among black women

The purpose of this study was to determine the effects of Type A behavior and family history of hypertension on cardiovascular reactivity to mental stress in a group of employed black women. Measures of heart rate and of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were taken at rest, during a mental arithmetic task, and during the Type A Structured Interview (SI). Results indicated that the Type A behavior pattern was associated with SBP and DBP hyperresponsivity during the SI but not during mental arithmetic. Additionally, certain speech components of the Type A pattern, as well as features of the potential-for-hostility component, were also related to cardiovascular responses during the SI. Family history of hypertension did not influence the cardiovascular parameters either alone or in combination with Type A behavior. The results suggest that many of the cardiovascular response characteristics of the Type A pattern that have been observed in predominantly white samples also hold true for blacks. Replication of these findings with other subgroups of blacks, such as young females and middle-aged males, will help document the generality of these findings within the black population.     

Actual and Perceived Group Performance as a Function of Group Composition: The Moderating Role of the Type A and B Behavior Patterns1

This study examined the moderating influence of the Type A and B behavior patterns on group performance and group functioning. Type As and Bs were assigned to different roles in groups given the task of deciding what items to transfer from a sinking ship to a life raft. Results indicated that groups with Type A leaders in conflict with a Type A group member arrived at relatively poor decisions. Type A leaders, however, also were perceived by their groups to be more competent than were Type B leaders. These results suggested that the Type A behavior pattern can have the paradoxical effects of hindering group problem-solving and of leading others to view Type As as more competent than Type Bs because of their active dynamic style.     

Orangutans (Pongo abelii) "play the odds": information-seeking strategies in relation to cost, risk, and benefit

Recent research has examined whether animals possess metacognition, or the ability to monitor their knowledge states. However, the extent to which animals actively control their knowledge states is still not well delineated. Although organisms might be capable of seeking information when it is lacking, it does not mean that it is always adaptive to do so. In the present set of experiments, we examined the flexibility of this behavior in captive orangutans (Pongo abelii; two adults and one juvenile) in a foraging task, by varying the necessity of information-seeking, the cost associated with it, the likelihood of error, and the value of the reward. In Experiment 1, subjects searched for information most often when it was "cheapest" energetically. In Experiment 2, subjects searched for information most often when the odds of making an error were the greatest. In Experiment 3, subjects searched for information more when the reward was doubled in value. In Experiment 4, adult subjects adapted to risk/benefit trade-offs in their searching behavior. In every experiment, subjects sought information more often when they needed it than when they already knew the solution to the problem. Therefore, the current research suggests that information-seeking behavior in orangutans shows a sophisticated level of flexibility, comparable to that seen in human children, as they appear to "play the odds" when making the decision to seek information or not.     

Type A behavior pattern, parental history of hypertension, and cardiovascular reactivity in college males

Two risk factors for cardiovascular disorders, parental history of hypertension and the Type A behavior pattern, were investigated concurrently with respect to cardiovascular reactivity to challenging situations. Sixty-four college males were given both the Structured Interview (SI) and Jenkins Activity Survey (JAS) for the Type A behavior pattern and a family health questionnaire to determine parental history of hypertension. The students were monitored for blood pressure (BP), heart rate (HR), and pulse transit time (PTT) response to four tasks: cold pressor, isometric handgrip exercise, a reading comprehension task, and backwards digit span. Type As based on SI classification had significantly higher HR levels across all tasks than did Type Bs, as well as higher diastolic BP levels in the cold pressor task. No main effects for Type A-B using JAS classification were found. Positive parental history students had higher HR and shorter PTT levels across all the tasks. Type A and parental history did interact in a limited way on some tasks, but the interactions were also dependent on the Type A classification used.     

Type A behavior pattern and self-evaluation of abilities: empirical tests of the self-appraisal model

The self-appraisal model proposes that Type A behavior reflects active attempts to generate diagnostic information about abilities, particularly in situations that evoke high uncertainty. In Study 1, subjects were provided feedback indicating high or low uncertainty about underlying abilities in two domains. When subjects were more uncertain of their ability in one domain than in the other, Jenkins-Activity-Survey-defined Type As (but not Type Bs) subsequently constructed tests that were biased to assess the more uncertain domain. Study 2 examined postfailure performance. The model holds that Type As perform poorly because they suspend information gathering when faced with evidence that requisite abilities are absent. Results indicated that deficits emerged only if Type As believed that a second task assessed the same abilities as the initial task on which they failed. A final study examined social comparison among Type As and Bs. Results indicated that Type As engaged in social comparison to obtain diagnostic information, primarily when they were uncertain of their ability levels.     

Time Urgency and the Type A Coronary-Prone Behavior Pattern1

Two experiments were conducted to examine behavioral consequences of a sense of time urgency, which presumably characterizes individuals classified as manifesting a so-called “Type A” coronary-prone behavior pattern. Experiment I indicated that time-urgent Type A Ss were reliably less successful than noncoronary-prone “Type Bs” in performing a task requiring a low rate of response for reinforcement (DRL). Type As were not only unable to delay their responses; they also showed greater evidence of tension and hyperactivity than Type Bs during DRL performance. Experiment II extended these results to the interpersonal domain. Time-urgent Ss became more impatient and irritated than less urgent Ss when both types were systematically slowed down in their efforts to reach a solution on a joint decision-making task. The results were discussed in terms of a conceptualization of the A-B dimension as reflecting differential expectations of and needs for environmental control. Additional evidence was presented in support of this approach. Consideration was also given to possible physiologic mechanisms mediating the relationship between psychological variables such as the Type A pattern and actual occurrence of coronary heart disease.     

Type a behavior,irritability, and cardiovascular response

Previous research suggests that high levels of hostility may augment the cardiovascular reactivity and risk of coronary heart disease (CHD) associated with Type A behavior. In contrast, other research indicates that the tendency to deny or suppress anger is associated with enhanced cardiovascular reactivity and risk of CHD. To delineate further the combined role of anger processes and Type A behavior in CHD risk, this study examined the interactive effects of Type A behavior and self-reported irritability on cardiovascular response to a challenging mental task. Type A and Type B college students were further classified as either high or low in self-reported irritability. Type A subjects who were low in self-reported irritability evidenced greater cardiovascular reactivity (i.e., systolic blood pressure and pulse rate) than did Type B subjects low in irritability. However, Type A subjects who were high in irritability tended to demonstrate less cardiovascular response than Type B subjects high in irritability. Further, Type A's low in self-reported irritability evidenced greater cardiovascular response than high-irritability Type A's. It is suggested that reduced reporting of irritability by Type A's may reflect suppression or denial, and further that this reduced reporting is associated with enhanced cardiovascular responsivity.     

Cognitive appraisal of daily hassles in college students showing Type A or Type B behavior patterns

To test the hypothesized role of cognitive appraisal in Lazarus' model of life stress, 312 male and female undergraduate students completed the Hassles Scale and the Jenkins Activity Survey, Form C. Based upon their scores on the Type A scale of the Jenkins Activity Survey, subjects showing Type A behavior pattern differed significantly from subjects showing Type B behavior pattern on both reported frequencies of hassles (higher for Type A scoring subjects) and hassles content pattern. This is interpreted primarily as supportive of the cognitive appraisal variable in Lazarus' life stress model.     

Effects of parental styles on anxiety and type A behavior pattern

The present study examined the effect of reported parental styles on 35 undergraduates' anxiety and the Type A behavior pattern. The modified version of Kelly and Goodwin's Parental Control-style Questionnaire, the State-Trait Anxiety Inventory, and the student version of the Jenkins Activity Survey were administered. Analysis showed that the subjects who had autocratic parents exhibited more Type A behavior pattern as well as having higher scores on the anxiety scales than those who had either permissive or democratic parents.     

Type A behavior, personality hardiness, and cardiovascular responses to stress

Type A behavior and hardiness were examined as predictors of cardiovascular responses to stress in 68 male undergraduates. Systolic and diastolic blood pressure (SBP and DBP) and heart rate were monitored while subjects performed a difficult mirror-tracing task. Type A assessments based on the Structured Interview, but not those based on the Jenkins Activity Survey, were associated with significantly enhanced SBP and DBP elevations. Hardiness was associated with significantly reduced DBP responsiveness. In addition, a significant interaction indicated that the Type B-high hardiness group showed the least DBP reactivity. A near-significant interaction (p = .06) suggested that Type B-high hardiness subjects also reported the least anger. Further exploration of the data indicated that the challenge component of hardiness accounted for its relationship to DBP reactivity. These results have implications both for the psychophysiologic study of Type A behavior and for understanding the health-promoting effects of hardiness.     

Empirical support for a Type A belief system

Much of the research on Type A behavior has focused on overt manifestations of the pattern; consequently, the underlying psychological dimensions are poorly understood (Matthews, 1982). Price (1982) has proposed an elaborate, but empirically unvalidated, model suggesting that a specific set of beliefs underlies the Type A behavior pattern. A series of experiments was conducted to test the validity of Price's model and to develop a device for assessing these beliefs. The internal consistency and test-retest reliability of this measure were .94 and .84, respectively. Significant positive correlations were found with traditional measures of Type A behavior as well as various facets of anger and anxiety. Finally, subjects who endorsed a high degree of Type A beliefs set significantly higher performance standards and were less likely to achieve these standards than their low-scoring counterparts. Results are discussed with regard to the theoretical construct of Type A as well as their implications for future research and treatment.This research is an extension of a study presented at the 92nd meeting of the American Psychological Association, Toronto, Canada, August 1984Special thanks to to Drs. James A. Blumenthal, Martin T. Gipson, Abby C. King, and Ellie T. Sturgis for their helpful comments in the preparation of this article.     

Preference for control and the coronary-prone behavior pattern: "I'd rather do it myself"

We explored differential preference for control among Type A and Type B individuals. Forty-six subjects were threatened with an aversive event (loud noise) and were allowed to choose whether to turn off the noise themselves or to yield control to another (more competent) individual. The results showed that Type B subjects (regardless of sex) tended to relinquish control to their more competent confederates and thus reduce the aversive stimulus, whereas the choice behavior of Type As was less clear. In addition, although female subjects tended to yield control, male subjects were more inclined to retain it. Because the willingness to yield control in general appears to be stronger in women than in men, the behavior observed in Type As may be partly moderated by the subject's sex. Although there were suggestive trends in the data, the central psychological features of the Type A pattern remain ambiguous and await studies in which researchers explore these effects, using a variety of situations and larger sample sizes.     

Type A behavior, achievement striving, and a dysfunctional self-evaluation system

We conducted two experiments to examine the relations among characteristics of how Type A individuals strive for achievement, including goal achievement, self-evaluation, and psychological distress. We evaluated these relations as subjects performed two sequential general information tests. Experiment 1 indicated that achievement striving associated with the Type A behavior pattern is characterized by a tendency to set personal goals in excess of performance and is associated with a low probability of achieving goals. The results of Experiment 2 indicated that the achievement strategy Type A individuals adopted was associated with low self-evaluation of their actual performance. Furthermore, a pre- and postexperiment self-report questionnaire of psychological state suggested that failure to achieve personal goals was related to increased psychological distress. The results of our study suggest that unrealistically high performance standards and failure to achieve personal goals may be a mechanism that triggers the negative psychological states and performance dissatisfaction associated with the Type A behavior pattern. Our study also supports theoretical conceptualizations that excessive achievement striving can act as a potential motivational mechanism but can also have potential pathogenic consequences through misregulation of achievement expectancy and evaluation.
