Colored aftereffects produced with moving edges

Colored aftereffects that lasted as long as 6 weeks were produced with moving patterns of parallel black and white stripes or with black and white spirals. During adaptation, the patterns moved periodically in opposite directions, each direction paired with one illuminant, red or green. When the moving patterns were later viewed in white light, S saw the red and green colors, but they were related in the opposite way to the direction of motion. The red and green aftereffects were also produced by other pairs of illuminants, red and white, white and green, reddish-yellow and white, and white and greenish-yellow. The aftereffects did not occur unless, during adaptation, the stripes moved in both directions, each direction paired with a different color. The aftereffect was elicited by stripe motion over the retina—it was seen when the eye swept over a pattern of stationary stripes. The aftereffect desaturated when the retinal orientation of the stripes was changed from the adaptation orientation. Saturation was increased by longer exposure and slower speed during adaptation and by faster speed and a more rapid rate of altemation during the test. The luminance of the adaptation light seemed to have little effect. The aftereffect did not transfer from one eye to the other, and it did not change retinal locus, as was shown when clear images of a colored square that lasted several days were produced with a spiral. S ftxated the spiral’s center. The spiral rotated altemately in opposite directions. A red square with a green surround was projected on the center of the spiral when it rotated in one direction; a green square with a red surround was used when it rotated in the other direction. Following 50 min of adaptation, colored images of the squares were seen when the center of the spiral was ftxated and the direction of     

Effects of musically evoked affect on women's interpersonal attraction toward and perceptual judgments of physical attractiveness of men

In a between-subjects design, female subjects evaluated photographs of attractive and unattractive stimulus males while listening to positive affect-evoking rock music, negative affect-evoking avant-garde music, or no music at all. Consistent with previous research, subjects evaluated attractive stimulus males more positively than unattractive males on a variety of interpersonal judgment dimensions. Furthermore, subjects responded with more positive evaluations of personal character of, and attraction toward, stimulus persons in the rock music as compared to the avant-garde music condition. Finally, assessments of physical attractiveness were influenced by the music conditions, with stimulus persons judged of greater physical attractiveness in the rock as compared with the avant-garde music condition. The results are discussed in terms of extending the Byrne-Clore reinforcement-affect model of interpersonal attraction.     

On the brightness of short and long flashes

The equation proposed by S. S. Stevens to describe the relations among brightness, intensity, and duration involves assumptions that are here made explicit. The equation is shown to apply to earlier studies designed to measure critical duration.     

Information available In brief tactile presentations

Two experiments investigated characteristics of Immediate recall for brief tactile stimuli applied to the 24 interjoint regions of the fingers of both hands (thumbs excluded) The obtained Immediate-memory span varied from 35 to 7,5 stimulus positions correct after correction for guessing, similar to the results In analogous visual studies, Properties of any hypothetical tactile short-term memory were studied by requiring subjects to report only a specified portion of the stimuli presented, and by varying the time of occurrence of the marker specifying which portion of the stimuli to report, In this partial-report condition, subjects had more stimulus information available at the time of reporting than their immediate memory spans indicated, provided that the stimulus marker occurred within 0.8 sec after stimulus termination, The data suggest that at least for the amount of training employed here, any tactile short-term memory has much less capacity than an analogous visual short-term memory.     

Gender and family factors as predictors of late adolescent emotional expressiveness and adjustment: A longitudinal study

This study examined the longterm effects of the socialization of emotion in a sample of European American families. Late adolescents, whose families had been more emotionally expressive and accepting of emotions when they were in fifth grade, were more likely to report showing emotions not traditionally associated with their gender roles—specifically, males reported a greater propensity for crying, and females reported a greater tendency to express anger. In addition, in late adolescence, greater frequency of showing fear and showing warmth or affection were associated with higher levels of social and psychological adjustment—whereas crying was associated with better adjustment for males and poorer adjustment for females. Overall, adolescent females tended to report a higher level of emotional expressiveness and a higher level of family support of emotions than did adolescent males.     

Multiple trajectories of physical aggression among adolescent boys and girls

Latent growth mixture modeling was used to identify discrete patterns of physical aggression from Grades 7 to 11 among a sample of 1,877 youth. Four trajectory classes adequately explained the development of physical aggression in both boys and girls: Low/No Aggression; Persistent High Aggression; Desisting Aggression, characterized by decreasing risk throughout adolescence; and Adolescent Aggression, characterized by low early risk that increases until Grade 9, levels out, and then declines in late adolescence. Girls were less likely than boys were to be in any trajectory besides the Low/No Aggression trajectory. Parental supervision, deviant peer association, academic orientation, impulsivity, and emotional distress at Grade 7 were all strongly associated with trajectory class membership. These associations did not differ by gender. These findings strongly suggest that the processes involved in the development of physical aggression in adolescence operate similarly in boys and girls.     

To reason or not to reason: is autobiographical reasoning always beneficial?

Autobiographical reasoning has been found to be a critical process in identity development; however, the authors suggest that existing research shows that such reasoning may not always be critical to another important outcome: well-being. The authors describe characteristics of people such as personality and age, contexts such as conversations, and experiences such as transgressions, which may hinder adaptive reasoning. They also propose alternatives to autobiographical reasoning for managing challenging events and constructing the life story, which include different kinds of meaning-making than those primarily focused on in the current literature.     

Contrasting jail diversion and in-jail services for mental illness and substance abuse: do they serve the same clients?

Baseline data from a study of jail diversion services and in-jail behavioral health services were used to examine the differences in clients served by these two models of responding to people with co-occurring mental health and substance abuse problems in the criminal justice system. Clients of the diversion service had more acute psychiatric symptoms and were more likely to have a diagnosis of psychosis NOS. Clients of the in-jail service were more likely to have been on probation or parole in the past and to have received substance abuse treatment. Different service models may attract and serve different populations of clients. Diversion services may cast a wider net that includes clients who may not have otherwise been involved in forensic services.
