Handgun Ownership and the Religion Factor

This article addresses the relationship between religious affiliation and a very specific form of firearms ownership, that is, handgun ownership. Literature is reviewed relative to explanations of gun ownership. A test of the hypothesized relationship between religious affiliation and handgun ownership demonstrated a statistically significant ( p < 0.03) association. Protestants were found to have a disproportionately high level of handgun ownership compared to other religious groups. Speculation for this finding is reviewed relative to other recent research on this topic.     

An "Epidemic" Model of Adolescent Cigarette Smoking

The prevalence of regular smoking increases rapidly during adolescence. We applied modeling methods from the study of epidemic infectious disease to smoking behavior. Our "epidemic" models dealt with the process of transition among four states: nonsmoker (susceptible), trier (exposed), regular smoker (infected), and ex-smoker (recovered). The best fitting model was one in which the transition from nonsmoker to trier was a social contagion process where nonsmokers contacted either triers or regular smokers. All other transitions were treated as constant rate processes in which a constant proportion of eligible individuals made the transition in a given year. The recursive equation model embodying these assumptions was able to predict accurately the proportion of adolescents in each state in Grades 6–11. Our results support a "stage" model of smoking, suggesting that different psychological and physiological processes are involved in the initiation of smoking than in developing a habit of regular smoking. A possible sex difference was found in the non-contact transition between trier and smoker states, with the transition being more probable in females than in males.     

Developmental amnesia

The concept of developmental amnesia is proposed to describe the impairment of normal memories during a person's school age life. One hundred psychotherapy patients were interviewed and the age of earliest memories ranged from 1–12 years, with a mode of 5 years. Memory was continuous for 53% of patients by 1st grade, while 18% reported life memory was still episodic at age 18 or later. Parental alcohol problems were associated with delay of continuous memories.     

The valuing process: A study of favorite songs and the inner experience of persons diagnosed with schizophrenia

Since valuing is a process grounded in the organizational tendency of human behavior, the characteristics of a highly valued object should reflect the experience of the individual who selects it. This research compared the favorite songs of fourteen individuals diagnosed with schizophrenia to their inner experience as assessed in a standard interview. Many relationships were revealed between the two, often pertaining to important issues identified in theories of schizophrenia. Results may have therapeutic applications and shed light on processes through which psychological difficulties persist.     

Integration of the big five and circumplex approaches to trait structure.

To integrate the 5-dimensional simple-structure and circumplex models of personality, the Abridged Big Five Dimensional Circumplex (AB5C) taxonomy of personality traits was developed, consisting of the 10 circumplexes that can be formed by pitting each of the Big Five factors against one another. The model maps facets of the Big Five dimensions as blends of 2 factors. An application to data consisting of 636 self-ratings and peer ratings on 540 personality trait adjectives yielded 34 well-defined facets out of a possible 45. The AB5C solution is compared with simple-structure and lower dimensional circumplex solutions, and its integrative and corrective potential are discussed, as well as its limitations.     

Consensus at zero acquaintance: replication, behavioral cues, and stability.

That observers tend to agree in their ratings of a target even if they have never interacted with that target has been called consensus at zero acquaintance. The basic finding that consensus is highest for judgments concerning a target's degree of extraversion (EV) and somewhat weaker for judgments of conscientiousness is replicated. Several potential observable cues that might be used by judges when rating targets are examined. The finding that ratings of physical attractiveness correlate with judgments of EV is replicated. In Study 1, rapid body movements and smiling were also found to correlate with EV judgments. The level of consensus declined when initially unacquainted Ss interacted one-on-one (Study 2), but did not decline--and even increased--when Ss interacted in a group (Study 3). Ss judged as extraverted at zero acquaintance were also seen as extraverted after interacting with others.     

Social support, depressed mood, and adjustment to stress: a genetic epidemiologic investigation.

A survey of 821 same-sex female twin pairs from a population-based registry assessed 8 dimensions of social support and social integration. Twin analyses documented significant common environmental influences on 5 of these 8 measures and significant genetic influences on 5 of the 8. A decomposition of the multiplicative association between support and a measure of stressful life experiences in predicting depressed mood--an association typically interpreted as providing evidence for a stress-buffering effect of social support--shows clearly that it is the environmental and genetic factors that cause support, rather than support itself, that buffer the effects of stress on mood in most cases. We discuss the implications of this result for future research on the relationship between social support and psychopathology.
