A new history of Hartley's Observations on Man

In 1749 David Hartley published his Observations, a work of great historical significance, yet the history of the Observations has been frequently debated. Establishing an accurate history of the Observations is, therefore, warranted. This has been undertaken here by reexamining known source materials, as well as additional primary documents not previously applied to Hartley studies. Significant historical information has been gleaned from transcribing the Hartley-Lister shorthand correspondence. The synthesis of material from these sources has led to a new history of the stages of conceptual development, composition, and publication of Hartley's Observations that differs substantially from previous accounts.     

Effects of a limited nap on night sleep in older subjects

The night sleep of sixteen 50-60-year-old women, which had been preceded by either afternoon naps or no-nap control periods, was assessed by polygraphic and subjective measures. There were 2 nap and 2 non-nap nights. The naps were limited to a 1-hr opportunity. The measures of all subjects, good nappers (more than 20-min sleep on both nap occasions), and subjects with 50-min or more nap time, were separately analyzed. The null hypothesis of a nap effect could not be rejected. Within limits, naps may be recommended to offset the common night-time awakenings in older persons.     

Dugald Arbuckle—Dialogue With Jerry Pine

Dugald S. Arbuckle, an advocate of human rights in counseling and writer on the implications of existential humanistic thought in psychotherapy and education, reflects on the roots of his humanistic thinking from his boyhood days in the mining country of the Western Canadian Rockies through more than 30 years of teaching and private practice. A major contributor to the literature that has shaped counseling and psychotherapy, Arbuckle is the founder of the graduate Program in Humanistic Counseling at Boston University and served as president of the American Personnel and Guidance Association (1959–60). In this dialogue he discusses a wide and provocative range of ideas with a former student, Gerald J. Pine, currently Professor of Counselor Education at the University of New Hampshire.     

Does changing behavioral intentions engender behavior change? A meta-analysis of the experimental evidence

Numerous theories in social and health psychology assume that intentions cause behaviors. However, most tests of the intention- behavior relation involve correlational studies that preclude causal inferences. In order to determine whether changes in behavioral intention engender behavior change, participants should be assigned randomly to a treatment that significantly increases the strength of respective intentions relative to a control condition, and differences in subsequent behavior should be compared. The present research obtained 47 experimental tests of intention-behavior relations that satisfied these criteria. Meta-analysis showed that a medium-to-large change in intention (d = 0.66) leads to a small-to-medium change in behavior (d = 0.36). The review also identified several conceptual factors, methodological features, and intervention characteristics that moderate intention-behavior consistency.     

Psychophysiological profiles of batterers: autonomic emotional reactivity as it predicts the antisocial spectrum of behavior among intimate partner abusers

On the basis of studies finding heart rate deceleration among severely violent (SV) batterers (J. M. Gottman et al., 1995) and unsuccessful psychopaths (S. S. Ishikawa, A. Raine, T. Lencz, S. Bihrle, & L. Lacasse, 2001), this study compares the physiological reactivity of SV batterers (n=35) with low-level violent (LLV) batterers (n=37) and nonviolent men (n=21) during 2 laboratory tasks. Men's heart rate and skin conductance level were recorded during baseline, a conflict discussion, and a standardized anger induction. Results suggest that autonomic hyporeactivity is a risk marker for antisocial features among SV men, whereas autonomic hyperreactivity is a risk marker among LLV men. Psychophysiological responding appears to be a stronger correlate of general antisocial behavior than of intimate partner abuse.     

The interplay between goal intentions and implementation intentions

Two studies tested whether action control by implementation intentions is sensitive to the activation and strength of participants' underlying goal intentions. In Study 1, participants formed implementation intentions (or did not) and their goal intentions were measured. Findings revealed a significant interaction between implementation intentions and the strength of respective goal intentions. Implementation intentions benefited the rate of goal attainment when participants had strong goal intentions but not when goal intentions were weak. Study 2 activated either a task-relevant or a neutral goal outside of participants' conscious awareness and found that implementation intentions affected performance only when the relevant goal had been activated. These findings indicate that the rate of goal attainment engendered by implementation intentions takes account of the state (strength, activation) of people's superordinate goal intentions.     

Junior High School Athletes Excel in Scholarship

Ninth grade boys from a California junior high school who were participants in interscholastic athletics were compared with non-participants with respect to academic achievement. The athletic group tested higher on academic ability on the School and College Ability Test and earned a higher academic grade-point average. When athletes and non-athletes were matched on SCAT test scores, the athletic group showed higher academic achievement. The majority of boys who participated in sports for only one semester did as well as or better academically during their semester of participation than they did the other ninth grade semester. An incidental finding of the study showed that boys in general showed improved grade-point averages in the ninth grade when compared with their eighth grade records.     

Shifting of attentional focus within and about a visual display

If several positions must be attended in a large visual display, does the efficiency of performance vary as a function of the display distance between these to-be-attended positions? Two previous experiments (Podgorny & Shepard, 1983; Shaw, 1978) gave conflicting answers. In the present experiments, eight-letter circular displays were briefly presented. On each trial one, two, or three positions of the display were cued or precued. The number of noncued display positions intervening between the cued locations varied from zero to three. The subjects' task was to rapidly discriminate between two target letters. Although reaction time was found to increase with increases in the number of cued locations, no significant or suggestive effects were found for the spacing or distance between the cued locations. The evidence strongly suggests that the subjects serially searched the cued locations, which further implies that attention can index locations in the visual field at a speed that is independent of the distance between these locations.     

Mood and sleep in aging women

The possible covariations of mood and sleep was examined in a group of 25 normal, aging women. Mood assessments made in the evenings of 3 consecutive days were independently related to both before and after sleep night. Only two sleep variables: sleep efficiency and latency to first rapid eye movement (REM) period--were reliably related to daytime moods. The relative paucity of relation between mood and sleep variables was interpreted as reflecting a general insulation of sleep from day-to-day mood variations.
