Negative implications of fragmented public perspectives toward local alcohol programs

Strengthening local alcohol programs so as to emphasize primary prevention is an active concern among mental health professionals; yet interventions intended to achieve this aim have produced only modest shifts in program orientation in most communities. An analysis of data obtained from those active in local affairs in a small community, using Q-sort techniques, suggested that contrasting perspectives toward alcohol abuse as a social problem may stand as an unseen barrier to relevant change.     

Detecting “cracks” in mental health service systems: Application of network analytic techniques

This paper argued that problems of coordination and integration of community mental health systems are best approached from a network perspective in which all linkages between agencies are considered simultaneously. Structural coordination and integration can be assessed through the analysis of these linkages. The utility of this approach was demonstrated by deriving a typology of system "cracks" from network analytic constructs. A network analysis of a community mental health service network was then generated to illustrate how these cracks can be empirically identified. It is suggested that mental health planners will find both the network analytic approach and the typology of cracks useful for addressing problems of coordination and integration.     

Eyeheight-scaled information about affordances: a study of sitting and stair climbing

Previous work has shown that both the perceived and actual critical (maximum) heights of surfaces that afford "sitting on " and "climbing on" can be expressed as constant proportions of each actor's leg length. The current study provides evidence that these judgments of critical action boundaries are based on an existing source of size and distance information that is already scaled with reference to the actor's eyeheight. In Experiment 1 changes in judgments of "perceived eyeheight" (an index of the intrinsic scalar) as a function of viewing distance were shown to be highly correlated with changes in the maximum height that was perceived to afford sitting on or climbing on. In Experiments 2 and 3 observers wore 10-cm blocks and made judgments about whether the heights of various surfaces afforded sitting or climbing. The use of eyeheight-scaled information as the basis for their estimates predicted the obtained pattern of errors in these judgments. With a modicum of experience wearing the blocks, however, observers were able to retune accurately their critical action boundary to a degree that would not have been predicted from their consistent overestimation of the height of the block on which they were standing. These results have implications for understanding how observers obtain information about their specific action boundary.     

Gender,sex roles,and attitudes toward war and nuclear weapons

The observation that men are usually more supportive of war than women had led several authors to suggest that masculinity plays a causal role in the decision to make war and stockpile nuclear arms. In order to examine the relationship between sex role orientation and attitudes towards war and nuclear weapons, gender and measures of sex role orientation were used to predict three attitudes about nuclear weapons and the use of military force. Two specific and two classes of hypotheses regarding the possible relationships among these variables were tested: masculinity, femininity, Masculinity × Femininity interaction, and Gender × Sex Role Orientation hypotheses. The results provided limited support only for the femininity hypothesis—that attitudes toward war are associated with feminine traits. However, neither masculinity nor femininity was found to be the only mediators of the gender/war attitude relationship, indicating that sex role orientation (and especially masculinity) should be given less emphasis when trying to explain the relationship between gender and attitudes toward war.The author gratefully acknowledges the helpful comments of Douglas Kenrick, Nancy Russo, and an anonymous reviewer on a earlier version of this paper.     

Of beasties and butterflies: Evidence for the stability and domain-specificity of individual differences in categorization

Previous research has failed to demonstrate unambiguously the relative stability across time and consistency across tasks of individual differences in categorization, or categorization breadth The present study of categorizing behavior in college students assesses breadth at each of four points in time over a six-week period Results are consistent with an interpretation of breadth as a highly stable individual difference variable, but one that is constrained by the nature of the stimulus sets employed High stability coefficients were observed for each of two redundant tasks In contrast, cross-task consistency indices were generally low Personality correlates of breadth were similarly weak and inconsistent Several variables are suggested that may attenuate the generality of categorization breadth The existence of multiple styles of categorization is discussed     

Attributional mediators of social inhibition and avoidance

People differ in the degree to which they become inhibited and avoidant when they feel socially anxious This study explored the hypothesis that characterological attributions for one's feelings of nervousness in social settings are related to social inhibition and avoidance In a preliminary study, the dimensions people use to explain their feelings of nervousness and relaxation were determined One hundred and twenty-five subjects then completed measures of social anxiousness, inhibition, and avoidance, and made attributions for feeling nervous and relaxed in 10 interpersonal scenarios As predicted, attributions of nervousness to characterological factors, such as ability and personality traits, correlated positively with social inhibition and avoidance Unexpectedly, behavioral attributions for nervousness also predicted inhibition and avoidance     

Statistics,data analysis and Psychometrika: Major developments

Approximately 15% of all papers appearing inPsychometrika during the period 1960–1984 have been statistical or data analytic in nature. While these papers cover a very wide range of issues and are technically quite similar to those appearing in other major statistical journals, collectively they possess features which make them identifiablyPsychometrika.     

Duration of negative practice and the reduction of leg pounding of a traumatically brain-injured adult

This study evaluated the relative efficacy of long (1 minute) and short (15 seconds) durations of negative practice for reducing self-stimulatory leg pounding of a traumatically brain-injured adult. In individual social skill training classes, long negative practice and short negative practice were administered concurrently in an alternating treatments design. Generalization of treatment effects outside of training sessions was assessed during the client's lunch period. The results revealed that both durations of negative practice were equally effective in reducing leg pounding during training sessions. However, the effects of training did not generalize to settings in which the practice contingency was not enforced. Pounding was more frequent and negative practice somewhat less effective during periods of high social stimulation.
