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.     

Interference Effects of Contextual Cues in Advertisements on Memory for Ad Content

The effectiveness of advertisements has been an issue of great concern to marketers, especially with the rapid increase in the number of marketing communications that the average consumer receives every day. Prior research has examined the impact of verbal interference on consumers’ memory for different elements of the advertisement—that is, interference caused by similar verbal elements in advertisements for brands in the same product category. This study examined the impact of similar contextual or background stimuli on consumers’ memory for different elements of the advertisement. Consumers were exposed to print advertisements for products in different product categories. The similarity of contextual cues—that is, background scenes—was manipulated (similar vs. dissimilar). Using a 2 (contextual cues interference: low and high) x 2 (processing goal: ad and brand) x 3 (cues: brand name, ad photo, product class) between‐subjects design, it was found that exposure to ads with similar contextual elements reduced individuals’ ability to recall not only contextual or background elements but also brand name from a target advertisement.     

Psychological type and attitude toward Christianity: a replication

A sample of 149 university students completed the Francis Psychological Type Scales together with the Francis Scale of Attitude Toward Christianity. The data indicated that university students classified as Feeling Types hold a more positive attitude toward Christianity than those classified as Thinking Types. These findings replicate the 1999 report of Jones and Francis.     

Identity motives underlying desired and feared possible future selves

Desired and feared possible future selves are important motivators of behavior and provide a temporal context for self-evaluation. Yet little research has examined why people desire some possible selves and fear others. In two studies, we tested the reflection of identity motives for self-esteem, efficacy, meaning, continuity, belonging, and distinctiveness in people's desired and feared possible future selves and in their possible future identity structures. As predicted, participants desired especially those possible futures in which motives for self-esteem, efficacy, meaning, and continuity would be satisfied, and they feared especially those in which the same four motives and, marginally, the motive for distinctiveness would be frustrated. Analyses supported an indirect path from belonging via self-esteem to desire and fear. Desired and feared possible future selves reflect potential satisfaction and frustration of these identity motives.     

Temporal brightness enhancement: Studies of individual differences

We have previously identified categorical individual differences in the occurrence of temporal brightness enhancement (TBE) by using a simultaneous brightness discrimination paradigm (Bowen & Markell, 1980).TBE is a nonmonotonic relation between brightness and pulse duration, pulses of intermediate duration (75–125 msec) can appear brighter than longer or shorter pulses of the same luminance. Three classes of observers can be defined based on whether they perceive TBE under one of two conditions of temporal asynchrony between a short test pulse and a longer (500 msec) comparison pulse:simultaneous onset of the pulses orsimultaneous offset. Type A observers show TBE for both asynchrony conditions; Type B observers show the effect for simultaneous offset but not simultaneous onset; Type C observers do not show TBE for either asynchrony. In the present study, we show that Type A and Type C observers maintain a constant brightness-duration relation as the asynchrony between test and comparison pulses is varied from simultaneous onset to simultaneous offset. Type B observers show a gradual shift in the brightness-duration relation as asynchrony changes. In a separate experiment, we find that practice has little effect on Type A and Type B observers but that Type C observers may change in classification to Types A and B over as few as five experimental sessions. The hypothesis that individual differences are due to differential “weighting” of chromatic (sustained) and achromatic (transient) visual channels is discussed.     

Functional connectivity dynamics during film viewing reveal common networks for different emotional experiences

Recent theoretical and empirical work has highlighted the role of domain-general, large-scale brain networks in generating emotional experiences. These networks are hypothesized to process aspects of emotional experiences that are not unique to a specific emotional category (e.g., “sadness,” “happiness”), but rather that generalize across categories. In this article, we examined the dynamic interactions (i.e., changing cohesiveness) between specific domain-general networks across time while participants experienced various instances of sadness, fear, and anger. We used a novel method for probing the network connectivity dynamics between two salience networks and three amygdala-based networks. We hypothesized, and found, that the functional connectivity between these networks covaried with the intensity of different emotional experiences. Stronger connectivity between the dorsal salience network and the medial amygdala network was associated with more intense ratings of emotional experience across six different instances of the three emotion categories examined. Also, stronger connectivity between the dorsal salience network and the ventrolateral amygdala network was associated with more intense ratings of emotional experience across five out of the six different instances. Our findings demonstrate that a variety of emotional experiences are associated with dynamic interactions of domain-general neural systems.     

Effect of Level of Challenge on Pressor and Heart Rate Responses in Type A and B Subjects1

The present study examined the relationship between the Type A coronaryprone behavior pattern and the magnitude of cardiovascular response induced by varying levels of environmental challenge. In a 2 × 2 experimental design, Type A and B (noncoronary-prone) subjects (n= 80) were randomly assigned to either high or low challenge instructional conditions for both the cold pressor (CP) and a choice reaction time task (RT). Overall, across both tasks, Type A subjects responded with greater systolic blood pressure (SBP) and heart rate (HR) elevation than Type B subjects. While these differences between the Types tended to be larger in the high challenge condition, some differences were also observed under low challenge. Component analyses of the Pattern revealed that high hostile/competitive Type A's responded to both low and high challenge instructions in the CP and RT tasks with physiologic elevations comparable to that displayed by globally defined Type A's receiving high challenge instructions. The present findings tentatively suggest that (a) high hostile/competitive Type A's respond to even mild challenge with enhanced physiologic response; (b) globally defined A's tend to evidence the physiologic elevations when specifically challenged; and (c) Type B's show much smaller physiologic reactions to such challenges. Consistent with previous research, comparison of Type A assessment techniques revealed that the Rosenman diagnostic interview was a better predictor of physiologic response than other questionnaire methods. Two hypotheses are advanced and future research recommended regarding possible relationships between environment, behavior, physiology, and disease.     

Familial similarity in Type A behaviour and physiological measurements as related to sex

Thirty-one families with pre-school children were examined with regard to Type A behaviour and cardiovascular and neuroendocrine measurements. Type A scores (MYTH) of the children from the ages of three to six were positively correlated with independent Type A measurements (Jenkins Activity Survey, Bortner Type A scale) of the parents (significant for fathers but not for mothers). The children's resting systolic blood pressures were significantly correlated with maternal and paternal values, while no significant familial aggregation was found for diastolic blood pressure, heart rate, catecholamine or cortisol excretion. The children's systolic and diastolic blood pressures and adrenaline excretion were significantly correlated between ages three and six. The results are consistent with the assumption that genetic as well as environmental factors contribute to the development of Type A behaviour. No significant association was found between Type A scores and physiological measurements during routine activities in the children or the adults.     

An MMPI typology of cocaine abusers.

Three types were found in a cluster analysis of scores on the Minnesota Multiphasic Personality Inventory (MMPI) of 100 men voluntarily presenting for treatment of cocaine abuse. Type 1 (n = 59) had a mean MMPI profile consistent with the hypothesized grouping of persons who self-medicate with cocaine as a means of overcoming depression. The relatively normal mean MMPI profile obtained by Type 2 (n = 37) suggested little indication of significant psychopathology. Type 3's (n = 4) mean MMPI profile suggested either severe disturbance or profile invalidity. Types were found to differ in the nature of drug use, reactions to cocaine, education level, and social class, but not on the scales of the Adjective Check List.     

Visual working memory capacity for objects from different categories: a face-specific maintenance effect

The capacity of visual working memory was examined when complex objects from different categories were remembered. Previous studies have not examined how visual similarity affects object memory, though it has long been known that similar-sounding phonological information interferes with rehearsal in auditory working memory. Here, experiments required memory for two or four objects. Memory capacity was compared between remembering four objects from a single object category to remembering four objects from two different categories. Two-category sets led to increased memory capacity only when upright faces were included. Capacity for face-only sets never exceeded their nonface counterparts, and the advantage for two-category sets when faces were one of the categories disappeared when inverted faces were used. These results suggest that two-category sets which include faces are advantaged in working memory but that faces alone do not lead to a memory capacity advantage.

A new driver behavior model to create realistic urban traffic environment

This paper presents a new driver behavior model, which emulates various driving styles (i.e. behaviors) for different categories of drivers. The model was highly parametric and was developed based on a two-layer Hierarchical Concurrent State Machines (HCSM) programming framework. Our study has been specifically oriented to create a realistic urban traffic environment with hazardous situations typical of real life in a driving simulator, and let the novice drivers to practice in a safe environment. In our study, we used TRAFIKENT driving simulator as a test-bed. Experiments and evaluations demonstrated satisfactory results in terms of behavioral validity of our model.     

Environmental demand and demand engendering behavior: an observational analysis of the type A pattern

In a prospective, observational study, we examined Type A behavior as a predictor of source of work demands, volume of work and nonwork activity, whether work begun was finished, and attention to more than one activity at a time. Police radio dispatchers (N = 72) were observed throughout one work shift, and half of the sample was observed on two additional work shifts. Behavioral categories showed substantial stability between observation occasions. Hierarchical regression revealed that two components of the broader Type A pattern, Hard-Driving Competitiveness and Job Involvement, were better predictors of work demands and behavior than was the global A score. Results support an interactional personality perspective in that Type As, relative to Type Bs, received more externally imposed demands from particular sources such as superiors or peers. However, these same Type As also generated more demand by simultaneously initiating work tasks for themselves and attending to multiple tasks.     

The effect of semantic relatedness on immediate serial recall and serial recognition

Several researchers have reported that learning a particular categorization leads to compatible changes in the similarity structure of the categorized stimuli. The purpose of this study is to examine whether different category structures may lead to greater or less corresponding similarity change. We created six category structures and examined changes in similarity within categories or between categories, as a result of categorization, in between-participant conditions. The best supported hypothesis was that the ease of learning a categorization affects change in within-categories similarity, so that greater (within-categories) similarity change was observed for category structures that were harder to learn.     

Type A behavior,anger expression,and reactions to anger imagery

The experiment investigated the effects of Type A behavior, anger expression, and gender on perceptions of control and heart rate. Jenkins Activity Survey defined Type A and B subjects, categorized as either high or low in anger expression, were asked to recall, image, and generate self-referent statements about angry situations. State anger and heart rate were measured during all of the anger induction conditions, and ratings of imagery vividness and perceptions of control for self and others were taken following the recalled and imaged anger conditions. The results, with both the heart rate and self-report measures, indicated that the effects of the independent variables were interactive and situationally dependent. Type A behavior was associated with increased heart rate in two experimental conditions (mood anger and recalled anger), and, in one instance, this effect was amplified in male subjects (recalled anger). The self-report results yielded interactional effects that most commonly took the form of high anger expression, with male Type A's providing higher ratings of state anger, more vivid anger imagery, and lower perceived self-control ratings than did other categories of subjects. Taken together, these results suggest that anger expressiveness, particularly among males, amplifies the usual reactions attributed to Type A's, and that such effects are mediated by the threat of loss of control. Further, the observed interactive relationships limit the generalizability of A/B differences and raise definitional questions about Type A behavior.     

High-risk situations associated with parasuicide and drug use in borderline personality disorder

Both parasuicide and drug use continue to be difficult problems to treat in borderline personality disorder (BPD). One useful approach that has not yet been applied to BPD is to develop a taxonomy of triggering situations for these problems. Once these high-risk precipitants are identified, then the behaviors can be targeted with skills training. This model has been applied by Marlatt (1996) with very influential results. To examine high-risk situations for parasuicide and drug use in BPD, the current study examined women with BPD who came to treatment for two different primary problems: parasuicide (N = 75) and drug dependence (N = 47). Participants identified the situation associated with highest risk for relapse in either the parasuicide or drug category. A taxonomy is presented, which divides results into six main categories. Differences between high-risk situations for drugs and parasuicide were also explored. Parasuicide was significantly more likely to be linked to interpersonal problems, whereas drug use was more likely to be preceded by addiction cues (i.e., being near drugs or people who use drugs).     

Stress and Distress as a Function of Jenkins Activity Survey-Defined Type A Behavior and Control Over the Work Environment

Although laboratory studies have demonstrated that situational factors which are particularly threatening to Type A individuals induce both Type A behaviors and cardiovascular reactivity, field studies have failed to demonstrate consistent differences between Types A and B in response to stress. Rhodewalt, Hays, Chemers, and Wysocki (1984) argued that this inconsistency is caused by the failure to take into account the individual's perception of the situation. They demonstrated that Type A individuals who perceived high levels of job stress reported more psychological and physical health problems than Type As under low stress or Type Bs under high or low stress. This study attempted to replicate this earlier finding, as well as identify factors in the situation which lead Type A individuals to perceive their job as stressful. Three hundred thirty-six male school principals (categorized as Type A or Type B by the Jenkins Activity Survey [JAS]) completed questionnaires assessing their degree of control in their work environment, perceived job stress, and physical and psychological well-being. A path mediation analysis indicated that Type A individuals reported more job stress under lower levels of perceived control, and that higher job-stress levels subsequently lead to greater incidence of physical and psychological symptoms, especially for Type As.     

The conceptual base view of categorization

An experiment was designed to show that some categories, called Type C categories, are mediated by an abstract, interpretively derived conceptual base. To this end, each of four groups of subjects ranked 10 sentences (instances) in terms of how well they illustrated the figurative meaning of a proverb (Proverb group), or how well they illustrated the meaning of an excellent interpretation of the proverb (Excellent Interpretation group), or a poor interpretation of the proverb (Poor Interpretation group), or an unspecified, unstated underlying meaning (Control group). The Excellent Interpretation groups' rankings correlated highly with standard ranks established by the Proverb group, but the Poor Interpretation group's and the Control group's ranking were uncorrelated with these two group's rankings. Apparently, the subjects in the Proverb group accomplished their rankings by using a conceptual base or microtheory similar in meaning to the interpretation used by the Excellent Interpretation group. Discussion centered on the question of whether the Classical, Probabilistic, or Exemplar Views of categorization (Smith & Medin, 1981) could account for the results. It was argued that they could not, basically because Type C categories are more dependent upon interpretive processes than the more perceptually based Type P categories to which these views have traditionally been applied.IBM.
