Gray-scale graphics using dot matrix printers

Gray-scale graphics can be printed on conventional dot matrix printers by varying the dot density, rather than the dot intensity. The technique described here takes advantage of the high-contrast print possible with these printers and the increased resolution available using compressed character sets. The reflectance of individual characters and symbols was measured with a photometer, and a character set was selected that increased from dark to light in equal logarithmic steps of reflectance. Various criteria for choosing dot patterns are discussed, and the technique is applied to two-dimensional visual field maps.     

Health and Well-Being in Highly Cohesive Units of the U.S. Army1

A large civilian literature on the role of social support in health and well-being suggests that military units high in unit cohesion should provide their members both significant protection from physical and mental illness and high levels of job satisfaction. This hypothesis was tested with a questionnaire survey of soldiers in Special Forces “A-teams”, generally viewed as the U.S. Army's most cohesive permanent units. As predicted, A-team soldiers reported greater physical and psychological well-being and greater satisfaction with job and career than did soldiers in conventionally organized units, be they Special Forces, airborne, or mechanized infantry. The best predictors in our battery of demographic, personality, and cohesion measures were ratings of social support from and satisfaction with one's Army unit, and relatively more “internal” scores on the Rotter locus-of-control scale. From these data and extensive participant observation we conclude that unit cohesion provides the soldier considerable protection from the stresses of military life, even in peace, and that it is organizational rather than individual variables that are primarily responsible for the very high levels of cohesion and/or social support in Special Forces A-teams.     

The effect of the repeated presentation of a standard interval on the reproduction of the standard

The Langley Porter Neuropsychiatrie Institute, San Francisco, California 94122 Eleven human Ss (five male and six female) reproduced intervals of 1, 2, and 3 sec delimited by clicks after the standard intervals had been repeated one, three, or five times. The absolute error of reproduction decreased with increasing repetition of the standard for intervals of 2 and 3 sec. The effect was more pronounced with increasing duration among female Ss.     

Saving psychological Solipsism

I am indebted to both Lynne Rudder Baker and George Graham for helpful, critical correspondence on an earlier draft of this paper. John Pollock and Keith Lehrer generously commented on that same draft. Conversations with Alvin Goldman, Joseph Tolliver and Juanita Simpson have been helpful on the matter of narrow content. None of these philosophers is liable for those of my mistakes that have resisted instruction.     

The effect of autonomy on counterfactual thinking about controllable events

We investigated the role of autonomy in counterfactual thinking in two experiments. Autonomy emphasises intrinsic motivation and reduced preoccupation with external outcomes. Experiment 1 demonstrated that autonomy influences both the number and content of counterfactual thoughts, particularly for individuals performing a task rather than reading about someone else performing a task. Experiment 2 investigated the performance improving effects of counterfactual thinking, while considering the role of autonomy. Individuals higher in autonomy were more likely to focus on undoing controllable aspects of their behaviour compared to individuals lower in autonomy. Controllable (versus uncontrollable) counterfactual thoughts were associated with greater performance improvement on a subsequent task. Self-regulatory traits such as autonomy may be important in the types of counterfactual thoughts that people generate. We discuss the mechanisms by which autonomy may exert an influence on counterfactual thinking and consider the implications of the findings for the functional theory of counterfactual thought.     

“Hooking Up” at College: Does Religion Make a Difference?

Recent attention from media, scholars, and religious leadership has focused on the dating activities of college students, particularly in relation to casual physical encounters or what some have termed "hooking up." In this article, we examine the impact of both individual and institutional religious involvement on "hooking up" in a national sample of college women ( N = 1,000). The results of our analysis reveal several important patterns. First, Catholic college women are more likely to have "hooked up" while at school than college women with no religious affiliation. Second, conservative Protestant college women are less likely to have "hooked up" while at school than college women with no religious affiliation; however, this difference is mediated or explained by church attendance, which is protective against "hooking up." Finally, women who attend colleges and universities with a Catholic affiliation are more likely to have hooked up while at school than women who attend academic institutions with no religious affiliation, net of individual-level religious involvement.     

The Relevance of People Versus Objects in Explaining Females’ Advantage over Males in Appearance Accuracy

Do females remember their surroundings better than males? Does it matter who or what is in those surroundings? In small groups, 108 undergraduates from a Midwestern university in the USA were instructed to pay attention to a videotaped person (target) while seated in an office with an experimenter (non-target). Afterwards, in a surprise recall task, participants’ memory for the appearance of the target, non-target, and office was tested. Females’ greater interpersonal orientation was predicted to give them an advantage over males in memory for only the people. Results showed that females had better memory for the target and non-target but not the office. Discussion centers on the importance of people versus objects in explaining females’ greater appearance accuracy.
