Cognitive-behavioral modification of coronary-prone behaviors: Proposal for a treatment model and review of the evidence

The Type A behavior pattern (TABP) has been proposed as a causal risk factor in coronary heart disease (CHD), and Cognitive-Behavioral treatment procedures have been proposed as a means of altering TABP. However, recent research suggests that only one component of TABP, hostility and anger, is the primary pathogenic factor in CHD. We review the research literature addressing the relationship of cognitive dysfunction and TABP and the relationship between cognitive dysfunction and anger expression. We then review the cognitive-behavioral therapy research literature regarding the modification of cognitive dysfunction, TABP and anger expression. While sparse, the research suggests that cognitive-behavioral treatments for anger and hostility hold promise for the treatment of individuals at risk for CHD.Jeffrey M.

Limbic networks and associative learning: I. Entorhinal contributions to instrumental conditioning

The hippocampal formation is a highly delineated brain structure that is believed to play a prominent role in learning and memory. The present experiment evaluated the contributions of medial and lateral perforant path input to bar press-conditioning under (a) continuous and (b) differential reinforcement of low rates of responding (DRL) schedules, and (c) shuttlebox avoidance conditioning. Bilateral deafferentation of either pathway had no effect on the acquisition of bar press responses or on performance under the DRL schedule. Deafferentation of the medial pathway facilitated acquisition of avoidance responses in a manner much like the effects seen in hippocampectomized animals. It is suggested that the medial perforant path participates in the expression of correlated patterns of neuronal discharge known to develop within the hippocampus and that this “model” serves to modulate the temporal characteristics of simple conditioned reflexes. Loss of the modulatory influence of the model may affect acquisition and extinction rates. Contributions of other hippocampal circuits are discussed in relation to established deficits. Preliminary results of this experiment were presented at the second annual convention of the American Psychological Society, Dallas, Texas, June 1990.     

Actual differences and stereotypical perceptions in body image and eating disturbance: A comparison of male and female heterosexual and homosexual samples

In the present study, 32 homosexual males (HMM), 32 homosexual females (HMF), 32 heterosexual males (HTM), and 32 heterosexual females (HTF) completed measures of body image disturbance and concerns with weight and dieting from five different perspectives: self, and typical homosexual male, heterosexual male, heterosexual female, and homosexual female. Participants were primarily Caucasian. Results indicated that, in general, HMMs and HTFs showed greater actual concerns with appearance, weight, and dieting, and were perceived to possess greater body image disturbance and dieting concerns compared to HTMs and HMFs. Subjects also held various stereotypic misperceptions about certain target groups such that HTFs and HMMs were predicted to possess greater body image disturbance and be more concerned with weight and dieting than was actually true. In addition, subjects made accurate predictions about HTMs overall, but were inconsistent in their predictions of HMFs on these measures. Results are discussed in terms of possible variation in the degree of importance these attributes may have for members of these four populations and how such differences may lead to an increased risk for developing eating disorders among heterosexual females and homosexual males.     

Limbic networks and associative learning: II. Entorhinal contributions to spontaneous alternation, passive avoidance, and taste aversion learning

The hippocampus plays an important role in learning and memory, but the precise nature of that involvement remains uncertain. Transection of the perforant path, a primary input pathway to the hippocampus, has been shown to produce changes in reaction to novelty and acquisition of active avoidance; the nature and magnitude of these changes vary with lateral or medial perforant path damage. In a series of experiments on adult rats, the role of these pathways in spontaneous alternation, exploration, acquisition and extinction of conditioned responses, passive avoidance, and conditioned taste aversion was investigated. Lateral transection reduced exploration while medial transection facilitated acquisition of an active avoidance response; no effects were observed on any other measure. Results are discussed in terms of what perforant path damage might reveal regarding the interactions of the hippocampus with other brain regions.     

HOLOMOVEMENT METAPHYSICS AND THEOLOGY

Abstract. The holomovement metaphysics of David Bohm emphasizes connections and continuous change. Two general movements through space-time extend Bohm's ideas. One is that the universe was nonlocal when it started but increases in locality. (With nonlocality, two simultaneous but distant events affect each other.) The other is the opposite movement or evolution toward increasingly complex systems exhibiting internal connections and a type of nonlocality. This metaphysics produces a theology when the holomovement is a model for God. Several topics follow, including global nonlocality, God as creator, God's transcendence and immanence, and God as personal. This theology shows promise but needs further development.     

The Situational Specificity of Validities: Correcting for Statistical Artifacts Does Not Always Reduce the Trans-Situational Variability of Correlation Coefficients

Validity generalization research suggests that much of the variability in validity coefficients is due to statistical artifacts, such as sampling error. Correcting for these artifacts usually reduces the trans-situational variability in validity coefficients, but the reverse can happen. Conditions under which corrections for statistical artifacts can increase the variability in validity coefficients are described, examples of meta-analyses reporting larger corrected than observed variance in validity are cited, and implications for the situational specificity of validity coefficients are discussed. In general, the true variability in validity coefficients based on large samples is often larger than the observed variability in test validities.     

THE TRANSMITTER-PERSISTENCE EFFECT:

Abstract— In four studies, Boninger, Brock, Cook, Cruder, and Romer (1990) found thai altitude change following exposure to a persuasive message persisted longer if recipients were expecting to have to transmit the message to someone else. The present experiment demonstrated thai this effect obtains only if the people preparing to transmit, as was the case in the studies of Boninger et a!., are denied the opportunity to do so. It is argued, then, that the findings of Boninger et at. may be attributable to a tendency toward thought perseveration triggered hy the failure to complete the transmission task, rather than being a consequence of the preparation to transmit per se.     

Optimism,perceived control over stress,and coping

To examine the ability of the expectancy-based personality dimensions dispositional optimism and perceived control over stress to predict the ways in which people characteristically attempt to cope with stress, 420 undergraduate students completed the Life Orientation Test (LOT; Scheier and Carver, 1985), a measure of perceived control over stress, and the dispositional version of the COPE Inventory (Carver, Scheier and Weintraub, 1989). The results revealed a modest but reliable positive correlation between optimism and the perceived control measure. Principal-components analysis of the COPE revealed a factor structure which was generally in accord with prior research. Optimism was positively correlated with active coping and positive reinterpretation, and negatively correlated with focusing on and venting of emotion. Perceived control over stress was negatively correlated with behavioural disengagement. Implications and directions for future research are discussed.     

ETHNICITY,ABILITY, ASPIRATIONS AND SOCIAL STATUS ATTAINMENT

In this study longitudinal data were used to examine relationships among children's intellectual ability, adolescents' aspirations and young adults' social-status attainment. The sample included 21-year-old Australians from Anglo-Australian, Greek and Southern Italian families. Regression surfaces were constructed from hierarchical models that examined possible linear, interaction and curvilinear associations among the variables. Typically, the findings indicated that in each ethnic group adolescents' aspirations had moderate to strong associations with status attainment. For Anglo-Australian and Greek young adults the relationships between ability and attainment were, in general, mediated by adolescents' aspirations. In contrast, for Southern Italians, ability continued to be associated with the educational and occupational attainment of the young adults.
