The misperception of rotary motion

Two principles for predicting the relative frequency of illusory reversals of rotating plane objects were derived and tested empirically. Ten objects, variously’ combining valid and confounding depth cues, were used. Predictions based on the principles were confirmed in every case. The results are offered as an improved explanation of the Ames trapezoid illusion and other illusions of rotary motion.     

The role of regression and range effects in determination of the power function for electric shock

A scale for the apparent intensity of electric shock applied to the forearm was derived from cross-modality matching functions relating noise level, number, and force of handgrip to both line length and shock. For each response mode, the effects of psychophysical regression were estimated from the line judgments and used to make adjustments in the corresponding shock judgments. For shocks ranging from (1.0 to 5.5 mA, combined estimates of subjective magnitude were found to grow as the 2.26 power of the stimulating current.     

Wrapping services in an urban setting

Efforts to reform services for children and their families in Baltimore City have included providing Wraparound services to youth returned or diverted from out-of-state residential treatment. We briefly present the history and evolution of the system reform efforts in Baltimore City that were necessary to support the implementation of a Wraparound model of service delivery. The characteristics of the Wraparound service model is presented along with the referral pathway of the youth into the service system, the components of the service delivery system and an overview of step-down services and linkages utilized to transition the youth. Data are presented that demonstrate the level of community adjustment of a subset of the 121 youth served through the Wraparound model in contrast to the level of community adjustment achieved by nonequivalent comparison groups. We discuss the use of report card type of outcome measures, its user-friendly features, limitations, and the developmental steps needed to refine it further.     

How are graphs read? An indication of sequence

Graphs are an extremely powerful communicative and analytical tool commonly used in both the behavioral sciences and computing (as well as many other fields). More than 2.2 trillion graphs are published annually, and these graphs are used to communicate a host of often very important information to readers. Yet despite the multitude of applications for which graphs are used, and despite the frequency of their use, little is known about how graphs communicate information or about the cognitive processes that readers use when they read and interpret the information presented within graphs. Insight into the answers to these questions can be obtained through the study of the techniques that people use to read graphs. This paper describes the research methodology and results of an empirical investigation into the viewing order in which readers choose to view the different components of graphs and into the length of time that readers spend studying each of these components.     

College Students' Judgments of Verbal Sexual Harassment1

Most studies of sexual harassment focus on physical coercion or pressure for sexual favors. This research attempts to outline the factors involved in verbal sexual harassment, which is conceived of as a speech act similar to taboo language, with conversational “rules” and semantic categories that differentiate it from merely inappropriate language. One hundred thirty-seven college students rated 37 sexual remarks for degrees of sexual harassment and inappropriateness. Total harassment scores correlated with total appropriateness scores at r = .68; although harassment ratings were high, remarks were judged more inappropriate than harassing. Five harassment factors and six appropriateness factors emerged. Women rated harassment factors of euphemisms and obscenity as significantly more harassing, and appropriateness factors of objectification, belittling competency, and name calling as more inappropriate. We conclude that men, who are less likely to be targets of harassment, are more used to taboo language and “naming” games, and are reluctant to admit to harassment, even when remarks are deemed inappropriate. Practical implications for defining verbal sexual harassment are discussed.     

Voice reaction time of stuttering and nonstuttering children and adults

The voice reaction time (VRT) of 5-yr old, 9-yr old, and adult stutterers and nonstutterers was investigated. Subjects initiated the sound / Λ / in response to fifty-five 1000-Hz tones of 1 sec duration. The tones were presented in five equal sets of 11 tones each with the silent intervals between the tones randomly selected to be 3, 4, 5, or 6 sec. Data analysis was based on responses 2–11 for each set. The VRTs for both the stutterers and the nonstutterers decreased significantly as an inverse function of age, with the largest decrease in reaction time occuring between 5 and 9 yr. The VRTs for the stutterers, however, were significantly slower than those of the nonstutterers at each of the three age levels. The results suggest that observed disruption in the laryngeal behavior for at least some stutterers may not result from the development of stuttering with age, but may contribute to early difficulty in the child's ability to produce fluent speech. Consideration of central factors are discussed.     

Differential effects of ethnic membership, sex, and occupation on the California Psychological Inventory

This study investigated the effects of race, sex, and occupation on college students' responses to the California Psychological Inventory. Analyses of variance of the standard CPI scales indicated numerous race, sex, and race X sex effects. A comparison of the results of factor analyses of the responses of black and white subjects (within each sex) indicated a similarity in factor structure between the two female groups, but not for the two male groups. These findings suggested that, due to these major differences in scale means and factor structure, care be taken in interpreting scores from the CPI when they are obtained from nonwhite populations.     

Two Models of the Trinity?

Contrary to a common assumption, I argue that there is full agreement between East and West on the issue of the relation between the divine essence and the divine persons. I defend this claim by using the understanding of universals found in D. M. Armstrong to cast light on the theories. Taking Gregory of Nyssa and John of Damascus as representatives of the Eastern tradition, I show that this tradition sees the divine essence as a numerically singular object that is wholly present in each divine person. The Eastern tradition explicitly sees this object as a universal. The Western tradition – exemplified in Augustine and Aquinas – likewise sees the divine essence as a numerically singular object that is wholly present in each divine person. But this tradition customarily denies that such an object could be a universal, on the merely philosophical grounds that universals are divided amongst the particulars that share them, and thus cannot be numerically one. Having shown the fundamental consonance of the two traditions, I argue by way of conclusion that differences between social and non–social theories of the Trinity depend entirely on the nature and extent of the features that are supposed to distinguish the persons from each other.     

Theoretical Antecedents of Distress Disclosure in a Community Sample of Young People1

The Distress Disclosure Index ( Kahn & Hessling, 2001 ) measures the tendency to disclose psychological distress and is important in understanding psychological well‐being, interpersonal relationships, and help seeking. This paper used the disclosure decision model ( Omarzu, 2000 ) to explore the theoretical antecedents of distress disclosure. Results of a community‐based survey of 17–18‐year‐olds in South Wales (United Kingdom), suggesting that private self‐consciousness, social support, and femininity were associated with higher distress disclosure. Shame was associated with lower distress disclosure. Moderating effects of gender and gender identity were also explored. Social support and femininity both interacted with gender to predict distress disclosure. The results suggest a number of interventions to increase distress disclosure in young men and women.
