EVOLUTION,CONTINGENCY, AND CHRISTOLOGY

Christopher Southgate has made important contributions to theodicy and the theory of divine action in light of the contingency in evolution and the suffering of creation. What happens then when one thinks through the implications of contingency for Christology? One can admit that aesthetic and moral judgments are products of a contingent history and yet affirm that they really are valid. Similarly, we argue, one can acknowledge the contingency of Jesus’ existence, actions, and subsequent impact and still maintain that his will was uniquely united with the divine will. Following a critical engagement with the recent work of Keith Ward, we argue that a high Christology is compatible with the actual contingencies of evolutionary and social history, without the necessity of interventionist divine action.     

Spectral indices of cardiovascular adaptations to short-term simulated microgravity exposure

We investigated the effects of exposure to microgravity on the baseline autonomic balance in cardiovascular regulation using spectral analysis of cardiovascular variables measured during supine rest. Heart rate, arterial pressure, radial flow, thoracic fluid impedance and central venous pressure were recorded from nine volunteers before and after simulated microgravity, produced by 20 hours of 6° head down bedrest plus furosemide. Spectral powers increased after simulated microgravity in the low frequency region (centered at about 0.03 Hz) in arterial pressure, heart rate and radial flow, and decreased in the respiratory frequency region (centered at about 0.25 Hz) in heart rate. Reduced heart rate power in the respiratory frequency region indicates reduced parasympathetic influence on the heart. A concurrent increase in the low frequency power in arterial pressure, heart rate, and radial flow indicates increased sympathetic influence. These results suggest that the baseline autonomic balance in cardiovascular regulation is shifted towards increased sympathetic and decreased parasympathetic influence after exposure to short-term simulated microgravity.     

Fear of AIDS: Its meaning and implications for clinical practice

Clinical reports have appeared about patients who present for mental health treatment with the major symptom of fearing that they have AIDS. The clinical reports of patients who fear AIDS are similar to those made many years ago by patients who feared syphilis. As with the syphilophobia of years ago, the AIDS group represents a divergent set of patients. Some can be described as the worried well who have realistic concerns because of a recent history of high risk behavior; others have unrealistic fears that are secondary to a major mental disorder such as hypochondriasis, depression, or schizophrenia. Suggestions are made to psychotherapists who encounter patients presenting with the problem of fearing AIDS.The views expressed here do not necessarily represent those of the Pennsylvania Psychological Association     

The contribution of anxiety and depression to fatigue among a sample of Australian university students: suggestions for university counsellors

Responses to the Zung Self-Rating Anxiety Scale (SAS: Zung, W. (1971). A rating instrument for anxiety disorders. Psychosomatics, 12, 371–379), the Self-Rating Depression Scale (SDS: Zung, W. (1973). From art to science: The diagnosis and treatment of depression. Archives of General Psychiatry, 29, 328–337) and the Fatigue Severity Scale (FSS) developed by Krupp and colleagues (Krupp, L.B., LaRocca, N.G., Muir-Nash, J., & Steinberg, A.D. (1989). The fatigue severity scale: Application to patients with multiple sclerosis and systemic lupus erythematosus. Archives of Neurology, 46, 1121–1123) were collected from 200 Australian university students to explore the links between these three disorders. Reliability data were satisfactory for all three scales and there were no significant gender or age-related differences between total scale scores. Factor analyses revealed a 5-factor solution for the SAS, a 6-factor solution for the SDS and a single factor for the FSS. There were 8 major and meaningful correlations found and these were entered into a regression of the SAS and SDS factor scores upon the single factor of the FSS. Fatigue factor scores were most powerfully predicted by psychomotor agitation, pain and resultant fatigue and cognitive and emotional arousal factor scores from the SAS and SDS. These data argue for an arousal/anxiety-fatigue-depression progression in disease that may be developmental or accumulative, with extreme levels of psychomotor arousal, resultant muscle fatigue and pain, plus concurrent elevated emotional state and cognitive arousal contributing to an eventual depletion of physical resources, leaving the individual in extreme fatigue. Implications for diagnosis and treatment by counsellors are discussed.     

Contributions to the history of psychology: CXVII. Who's who in American psychology: a citation study of introductory psychology textbooks

The author indexes of 15 introductory psychology textbooks were surveyed to identify the authorities cited most frequently. The five names cited most often in descending order were Freud, Bandura, Skinner, Piaget, and James. Differences from earlier comparable citation studies are discussed.     

Involvement of 5-HT1A receptors in animal tests of anxiety and depression: evidence from genetic models

Clinical studies have suggested the involvement of 5-HT1A receptors in anxiety and depressive disorders because partial 5-HT1A receptor agonists such as buspirone are therapeutic. The present review considers evidence from genetic animal models that support a role for 5-HT1A receptors in anxiety-like and depressed-like behavior in animals. Selective breeding for differential hypothermic responses to a selective 5-HT1A receptor agonist led to the development of the high DPAT sensitive (HDS) and low DPAT sensitive (LDS) lines of rats. The HDS rats differ from the LDS rats on several behavioral measures reflective of anxiety or depression, including reduced social interaction, reduced responding in a conflict task and exaggerated immobility in the forced swim test. However, they do not differ from the LDS rats in the elevated plus maze task, which is a commonly used test of anxiety. Nor do the HDS rats exhibit a typical anxiogenic response to the hippocampal administration of the 5-HT1A agonist. Although the HDS rats do exhibit elevations in 5-HT1A receptors in regions of the limbic cortex, it is not clear whether these increases account for the behavioral differences. Paradoxically, 5-HT1A receptor knockout mice also exhibit anxiety-like behavior in the plus maze, open field and conflict tests compared to wild type mice. However, the knockouts exhibited less immobility in the forced swim test than wild type control mice. Recent studies using selective regional reinstatement of the receptor have implicated the postsynaptic 5-HT1A receptors in these changes in anxiety-like behavior. Thus, preliminary evidence from two different types of genetic animal models suggests that anxiety-like behavior can arise if the 5-HT1A receptor function is eliminated or overexpressed. Further study with additional tests of anxiety are needed to confirm this intriguing relationship.     

Social interactions and cardiovascular reactivity during problem disclosure among friends

The authors examined the relations of social interactions with cardiovascular response in the context of two friends disclosing a problem. They also examined the relations of the sex composition of the dyad and partner gender-related traits (communion/agency) with social interactions. Same-sex and opposite-sex dyads (N = 79) came to the lab. One friend disclosed a real-life problem while the partner provided support; cardiovascular response was monitored. Women provided more emotional support than men, and this sex difference was due to women's higher levels of communion. Agency was linked with greater advice, whereas unmitigated communion was linked with greater negative interactions. Negative interactions predicted slower diastolic blood pressure (DBP) recovery, whereas advice predicted slower heart rate (HR) recovery. Sex composition of dyad moderated some of these effects.     

The relationship between executive function and verbal memory in Parkinson's disease

A growing body of evidence suggests that the various cognitive symptoms found in Parkinson's disease (PD) are secondary to executive dysfunction. Studies addressing this possibility for memory impairment specifically have not included measures of working memory nor have they ruled-out potential mediating variables such as overall level of cognitive impairment or depression. The purpose of this study was to include measures of these variables in determining the relationship between multiple aspects of executive function and delayed verbal recall in 32 idiopathic PD patients. Results were consistent with the original hypothesis and further suggest that working memory is a key factor in recall memory and may mediate the relationship between other executive measures and recall in PD.     

An overview of the major changes in the 2002 APA Ethics Code

This article summarizes the major changes that were made to the 2002 Ethical Principles and Code of Conduct of the American Psychological Association. The 2002 Ethics Code retains the general format of the 1992 Ethics Code and does not radically alter the obligations of psychologists. One goal of the Ethics Committee Task Force was to reduce the potential of the Ethics Code to be used to unnecessarily punish psychologists. In addition, the revised Ethics Code expresses greater sensitivity to the needs of cultural and linguistic minorities and students. Shortcomings of the 2002 Ethics Code are discussed.     

Ethics education after licensing: ideas for increasing diversity in content and process

Continuing professional education in ethics for psychologists is becoming more common, as psychology licensing boards in 14 states now require continuing education in ethics as a condition of licensure renewal. This article suggests ways to improve the quality of ethics continuing education by diversifying the content and teaching methods.
