Infants are trichromats.

Two experiments were conducted to demonstrate that human infants 3 months of age perceive color in a normal, trichromatic manner. In the first experiment, the visual attention of 30 infants was monitored in a habituation-dishabituation paradigm that used spectral and white lights with brightness factors eliminated. Infants discriminated white from monochromatic light in a region of the spectrum (490–500 nm) where color-normal adults can but color-deficient adults cannot. In the second experiment which also used a habituation paradigm, eight infants showed good discrimination between hues in a region of the spectrum (560–580 nm) where color-deficient adults typically show no hue discrimination. Results from these studies of the neutral zone and hue discrimination evidence trichromatic vision in infancy and are discussed in the context of their several clinical, social, and intellectual implications.     

Reference group perspectives and the vocational maturity of lower socioeconomic black youth

The reference group perspectives of 188 lower socioeconomic black high school seniors were found to be related to their career maturity. Students who evidenced an orientation toward middle-class reference group perspectives obtained higher vocational maturity scores than those who subscribed to reference perspectives traditionally associated with the lower class. Students' sex and family background were not related to their reference group perspectives or to their vocational maturity ratings. It was found that students' post-high school plans (either work- or college-bound) and their views of the opportunity structure of America were related to both their reference group perspectives orientation and their career maturity scores. Questions are raised concerning the relevance of the term career maturity for analyzing the career development of lower socioeconomic black youth.     

The relationship between goals,performance, success,self-image,and involvement under different organization climates

This is an attempt to test the following causal chain of relationships: →support←goals→performance→success→self-image→involvement→future goals as hypothesized in Hall's (Organizational Behavior and Human Performance, 1971, 6, 50–76) model of the development of work involvement. It was further hypothesized that there would be more evidence for the existence of this “success cycle” in an organization with a climate of high support and feedback than in an organization with lower levels of support and feedback. Data were collected near the beginning and end of the school year in two primary schools and analyzed with correlations and path analysis. The hypotheses received moderate support. As expected, more evidence for the success cycle was found in the high-support school. In the high-support organization, the person's own goals correlated with success, while in the lower-support school, the person's self-image was the main correlate of success.     

Nonverbal cues to sex-role attitudes

This study explored the relationship between self-reported attitudes toward “masculinity-femininity” and nonverbal behavior as judged by peers. Subjects (Ss) were preselected using an Mf questionnaire into: high-“feminine” males (N = 16) and females (N = 15) and low-feminine males (N = 16) and females (N = 15). The 62 Ss were videotaped in a 5-min standardized interview. Peer-age judges (Js) then viewed the videotapes without sound and asked to check which of the 170 adjectives describe Ss. Some Js were asked to rate average college male and female. A large number of adjectives discriminated the sexes (91 out of 170). Women were more often seen as warm, affable, oversocialized, emotional, and unstable. Men were seen as forceful, dominant, and detached. Sixty-two adjectives discriminated high- and low-feminine women. Feminine women were seen as warm, affable, oversocialized, and submissive, while low-feminine women were seen as dominant. High-feminine men were described as impulsive, dominant, and socially uneasy, while low-feminine men were seen as oversocialized and conventional.     

The influence of a model's reinforcement contingency and affective response on children's perceptions of the model

Following their observation of a videotaped model, boys and girls were asked to rate various characteristics of that model. In each of two experiments, the subjects were 90 primary grade children. The model's reinforcement (reward, punishment, or no consequences) and affective response (positive, neutral, or negative) constituted the independent variables. In both experiments, children who observed an affectively neutral model receive punishment, perceived his affective state as more negative than children who observed this model receive reward or no consequences. The converse attribution (i.e., inferring consequences based on depicted model affect) did not obtain. Also, data from both experiments supported the conclusions that (a) the punished model was less attractive than no-consequences and rewarded models, and (b) the model was perceived as less competent when he demonstrated negative affect or received punishment.     

Why additive utility models fail as descriptions of choice behavior

This experiment sought to determine whether previously found metric violations of additive expectancy-value models C.F. J. C. Shanteau, Journal of Experimental Psychology, 1974, 103, 680–691; J. G. Lynch and J. L. Cohen, Journal of Personality and Social Psychology, 1978, 36, 1138–1151) were attributable to the inappropriateness of these models or to nonlinearities in the relationship between numerical ratings and underlying psychological impressions. Undergraduate participants performed two tasks employing the same experimental stimuli. In the first task, they rated the subjective values of hypothetical bets, judged separately and in combination. In the second task, they made pairwise comparisons of the same bets in terms of preference. The use of the same experimental stimuli in both tasks allowed a test of alternative models of utility judgment through application of the criterion of scale convergence (M. H. Birnbaum & C. T. Veit, Perception and Psychophysics, 1974, 15, 7–15). Results suggested that the additive expectancy-value model of judgments of the utilities of combinations of outcomes should be replaced by a weighted averaging rule in which the weight given to the value of each outcome in the averaging process is greater when this value is negative and extreme than when it is neutral.     

Maintenance of fluency: A review

Three purposes for writing this paper are: to review specific work done on the maintenance of fluency in the post-treatment environment, to abstract and discuss pertinent issues in maintenance, and to present several speculative positions which might account for the relapse phenomenon and stimulate further research.     

Androgyny and traditional versus nontraditional major choice among college freshmen

The present study investigated the relationship of psychological androgyny to career choice among college freshmen. Women in home economics and engineering and men in engineering (N = 231) completed the Bem Sex-Role Inventory and rating scales of satisfaction with and certainty of college major and intended occupation. As a group, women in engineering scored in a more androgynous direction than did either men in engineering or women in home economics. Among sex-typed subjects, more women in engineering scored in a masculine sex-typed category than did women in home economics. Men and women in engineering did not differ on satisfaction and certainty ratings of major or career; however, feminine-typed women were significantly less satisfied with and tended to be less certain of their choice of major than other women in engineering.     

Effects of availability of feature changes on behavior segmentation

Thirty-five subjects segmented one of two videotapes of an actor methodically assembling 20 five-page questionnaires. In one sequence, the completion of each questionnaire resulted in a highly visible change in the stimulus fields: The top page of the stack changed from black to white or from white to black with the completion of each questionnaire. In a second sequence the action was identical, but the changing feature was concealed from view. Results disclosed that subjects viewing the tape with the visible change segmented the action on the basis of that change. Subjects viewing the same action without the visible change segmented the behavior into its fine-unit components, despite the fact that the higher-level organization in the behavior was readily understood.
