A developmental examination of ratings of associative strength

Ratings of associative strength between members of pairs of categorically related words were obtained for children from Grades 3,4,6, and 8 and for college adults. Correlations of ratings were high among the five grade levels, indicating that associative relations are an early form of semantic representation that change minimally in development.     

Effects of four psychological primary colors on anxiety state.

Effects of the four psychological primary colors were assessed by randomly assigning 40 undergraduates (13 male, 27 female) to 4 treatment groups, with each group receiving either red, yellow, green, or blue illumination. Anxiety state was assessed at 5-min. intervals using the State-Trait Anxiety Inventory. The red and yellow groups had significantly higher A-state scores than the blue and green groups, and these values did not change significantly during the 15-min. testing session.     

Psychology and self-help groups. Predictions on a partnership

Continued growth and increased legitimacy are anticipated for the American self-help group (SHG) phenomenon. Currently estimated at six and a quarter million participants annually, self-help groups will assume a central role in the nation's mental health delivery system over the next two decades. The first part of this article illuminates the self-help group phenomenon itself. Its scope, characteristics, supporting social climate, and associated research issues are reviewed. The second part is a futuristic examination of its interface with the newly industrializing world of health care. Massive increases in mental health services are predicted, especially via the SHG format. Theory development, research sophistication, changing SHG formats, a place in public policy, and acceptance into graduate curricula are also expected, as are collaborative relationships with a variety of professional disciplines. Psychologists are urged to enhance the relevance of the profession by taking an early leadership role in these developments.     

The impact of spouse monitoring on target behavior and recorder satisfaction

The objectives of this study were (a) to determine the impact of a spouse monitoring procedure on the target's (husband's) behavior and the recorder (wife's) view of the marriage and (b) to assess the relationship between the target's positive behaviors and the recorder's marital satisfaction rating. In one condition, husbands were informed that their behavior was being observed, whereas in a comparison group, husbands were kept unaware of the observation procedure. In both conditions, wives kept daily recordings of (a) positive behaviors emitted by their husbands and (b) perceptions of their marital relationships. No differences were found in rates of husbands' behavior or in wives' perceptions of their marriages as a function of the awareness manipulation. Analyses examining the relationship between spouse behavior and daily satisfaction ratings indicated a statistically reliable association, although the majority of variance in satisfaction ratings was attributable to unique subject variables.This article is based on a thesis submitted by the first author to the Department of Psychology of the University of Pittsburgh. The described research was supported in part by a Faculty Research Grant from the University of Pittsburgh awarded to the second author.     

Autonomic and behavioral effects of dextroamphetamine and placebo in normal and hyperactive prepubertal boys

The hypothesis is tested that the response to dextroamphetamine in terms of activity, attention, impulsivity, and autonomic activity is similar in normal (N) and hyperactive (H) children. Fourteen N and 15 H boys had skin conductance (SC), heart rate (HR), and finger temperature (ST) recorded during rest, presentation of eight 75- dB tones, and a reaction time (RT) procedure on three occasions: off drug (Day 1) and after ingestion (double-blind) of placebo and of .5 mg/kg dextroamphetamine. Both N and H groups showed drug effects, compared to placebo, of reduced motor activity and impulsivity, improved attention (RT), increased HR and HR slowing during RT foreperiods, and decreased ST. Both groups also had decreases in SC responsivity but in different parts of the test. Placebo compared to Day 1 produced increased activity and autonomic arousal but no change in RT. Stimulant drugs thus have similar behavioral and autonomic effects in both N and H boys, but the beneficial effects on behavior do not depend critically on increases in arousal.     

Idiosyncratic exceptions to the probability-matching decision-rule in visual discrimination

Human “Yes-No” signal-detection performance was tested under a modified perceptual-defense procedure. A majority of Ss tended to match the relative frequency with which they gave affirmative responses to the relative frequency at which signals were presented. These Ss thereby replicated the “probability-matching” behavior found in previous signal-detection and discrimination studies. However, in marked contrast to those previous results, another large set of Ss showed a tendency toward preponderant use of one of the two responses (typically, of “No”) rather than toward probability-matching. The evidence failed to suggest that the latter effect was related to a lesser ability to make the requisite sensory discrimination or to response inhibition induced by taboo stimuli.
