Needed: Standards for Occupational Licensing

Occupational licensing in the states constitutes a growing public problem from the legislator's point of view. No standards exist to permit sound judgments on specific proposals, and the operation of licensing acts tends to be in the hands of the occupation itself, operating with the sanction of the state. No groups exist to act as counter-lobbyists or disinterested public representatives to protect the public interest. Licensing sometimes closes off employment opportunities to young people entering the employment market. Standards for occupational licensing and the administration of licensing acts must be developed. Those involved in guidance and personnel work could perform a valuable public service by taking an interest in occupational licensing both from the theoretical standpoint and by actively providing advice to legislatures considering occupational licensing proposals.     

The effect of meaning on the allocation of visually induced movement

The directional characteristics of a meaningful target were found to affect its apparent motion when it was displaced relative to a neutral object. The effect was destroyed, however, when the target was surrounded by a frame. This was because the frame imparted a meaning which tended to override that conveyed by the target.     

On the handling of heavy bias in a self-paced task

Following an earlier observation that systematic variations in performance on a task with heavy frequency imbalance was correlated with fluctuations in the amount of bias in the input programme, an experiment was carried out to establish the roles of long and short term sampling. Two groups of subjects were trained on a self-paced, five-choice task. One group's input had an average of 68 per cent. bias on one source, the other had 44 per cent. on the same source. Analysis of data was carried out on three levels of local bias for each condition, one level being identical for both conditions. It was found that responses to the biased stimuli were determined by the average bias in each input sequence and not by moment to moment variations in that bias. The effect observed originally can therefore be accounted for in terms of a relatively simple additive model which includes the “repetition effect” first described by Bertelson.     

Observing responses in pigeons

Pigeons were trained on an observing-response procedure in which periods of VR 100 and EXT alternated unpredictably during a white light (mixed stimulus). During VR 100, responses on a food-producing key (the first key) were intermittently reinforced. Responses on the observing key (the second key) produced a green light (positive stimulus) when VR 100 was in effect, and a red light (negative stimulus) for EXT. The birds did not respond on either key during the negative stimulus, but they responded on the food-producing key when the positive stimulus appeared. When observing responses produced the positive or negative stimulus on FR, observing responses were maintained until the FR reached a maximum; beyond this, only food-producing responses occurred. When observing responses did not produce either stimulus, the observing-response rates fell to zero. With prolonged exposure to an FR 20 schedule of observing, observing-response rates during EXT were higher than during VR 100. Chlorpromazine hydrochloride decreased the total response output but markedly increased observing-response rates except when it was administered before sessions of observing response extinction.     

Dos-based exercises that demonstrate classic studies in human memory

Ten exercises are described that demonstrate some classic experiments in human memory and cognition. The studies, prepared in MEL Professional V1.0, have been incorporated in an undergraduate class taught by the author for a number of years. Survey data from students completing the course indicate that the exercises promote understanding of class material. Availability of the programs is described.     

Sense of Closeness to Parents and Family Rules: A Study of Arab and Jewish Youth in Israel

The present study investigated adolescents' perception of closeness to their parents and family rules restricting their conduct, in Arab and Jewish Israeli samples. A total of 854 11th-grade high school students reported their perceptions by a self-report questionnaire. Overall, the results indicate that the Arab youths perceived more closeness toward their parents and more rules restricting their conduct, compared with their Jewish counterparts. In both cultures, girls reported more restrictions on dating and leaving home than boys. Among Israeli Arab adolescents a positive association was uncovered between closeness to parents and number of rules. No such pattern was evident among Israeli Jewish youth. These and additional findings are discussed within the context of Triandis' cross-cultural dimension of collectivism-individualism.     

Sex Differences on Affective Dimensions: Continuing Examination

This study was designed to explore sex differences along several affective dimensions. A sample of 455 undergraduate students was administered several affective scales. A discriminant analysis was performed using the affective scales as discriminating variables and sex as the group variable. Significant sex differences were found on only two of nine affective scales, and the substantive significance of these differences seems to he minimal. The authors concluded that the promotion of faulty stereotypical beliefs should be abandoned in favor of increasingly complex inquiry in this area.     

The processing of inflected words

Summary Is an inflected word identified by first decomposing it into stem plus suffix or, instead, is it recognized as a whole? Several lexical decision experiments studied the recognition of inflected words in English (a language with few inflections) and Serbo-Croatian (a heavily inflected language). If recognition depended on decomposition, preceding the inflection with a brief exposure of the stem (<100 ms) should have primed the lexical entry for the stem and, therefore, facilitated recognition of the whole inflected word that followed. It did not. It was also found that the speed of recognizing an inflected word was more strongly associated with the frequency of the whole inflected form than with the frequency of its stem. The results suggested that in word recognition, lexical contact is first made with the whole word form. Nevertheless, morphological decomposition may still occur in subsequent processing.     

Traditional gender role beliefs and individual outcomes: An exploratory analysis

The results of a survey administered to 806 undergraduate students serve as the basis for analyzing the relationships among traditional gender roles, same-sex intimacy, and homophobia. High levels of homophobia and low levels of intimacy were found among those who believe strongly in the traditional roles. Previous research has shown both homophobia and a lack of intimacy to be harmful to individuals and for society. The present findings may, therefore, constitute empirical evidence of the negative effects of gender roles. Sex differences found in the survey results also support this contention. A general model of the consequences of traditional gender role beliefs for those who hold these views is also speculated.
