Two ways of scaling letter size across eccentricity were investigated in a choice reaction time (CRT) task. Experiments 1 and 2 tested cortical magnification theory (M-scaling), while Experiment 3 used scaled sizes drawn from Anstis’s regression formula (A-scaling). Experiment 4 compared both scaling techniques, together with the effect of exposure duration and the absolute size of the foveal letter. Results showed that scaling effectiveness improved when large rather than small foveal letters were used. A-scaling with a large foveal letter provided a good fit for the data at parafoveal locations, but underestimated the letter sizes needed at large eccentricities. M-scaling with a large foveal letter size produced CRTs that were independent of eccentricity. Exposure duration did not substantially affect performance.  相似文献

The choice-making behavior of 5 young children with developmental disabilities who engaged in aberrant behavior was studied within a concurrent operants framework. Experimental analyses were conducted to identify reinforcers that maintained aberrant behavior, and functional communication training packages were implemented to teach the participants to gain reinforcement using mands. Next, a choice-making analysis, in which the participants chose one of two responses (either a mand or an alternative neutral response) to obtain different durations and qualities of reinforcement, was conducted. Finally, treatment packages involving choice making via manding were implemented to decrease inappropriate behavior and to increase mands. The results extended previous applications of choice making to severe behavior disorders and across behaviors maintained by positive and negative reinforcement.  相似文献

This paper makes use of a unique data set fordoctoral-level biochemists, earth scientists,physicists, and physiologists to examine the question ofwhether the rewards to publishing in science are gender blind. The longitudinal nature of the data, andthe inclusion of different research outcome variables,permit the estimation of a wage-change model thatcontrols for fixed effects and productivity differences. We find little evidence that the reward processin academe during the 1970s was affected by gender. Wedo, however, find evidence that catch-up was occurring,implying that all was not well in the past for the women scientists in the study. [The1975 Survey of Doctorate Recipients indicates thatracial minority groups (Blacks, American Indians, andAsians) comprised, respectively, 5.9%, 6.3%, 2.8%, and 6.3% of the doctoral populations in physics,chemistry, earth science, and thebiosciences.]  相似文献

Among women, college is a high risk period for sexual assault by male acquaintances. Differences in expectations held by men and women may contribute to misinterpretation of social cues and subsequent sexual aggression and may impair women's ability to respond effectively. This paper presents findings from a predominantly Caucasian sample (85.9%) of college sorority (n = 66) and fraternity (n = 34) members regarding the social context within which they interact and their expectations regarding perpetration of and response to sexual aggression. Results showed differences in men's and women's expectations and responses, and in particular highlighted how men's expectations were related to women's resistance of unwanted sex. Understanding the cognitive processes that men and women draw upon in social interactions can be useful for developing sexual aggression prevention and resistance interventions.An earlier version of this paper was presented at the Council on Social Work Education Annual Program Meeting, March 1995, San Diego.

Abstract— People typically provide higher similarity ratings in response to the question "How similar is the typical preppie to you?" than to the question "How similar are you to the typical preppie?" Observed asymmetries in comparisons of the self and person prototypes have been offered as evidence that the self-concept acts as a habitual reference point in social judgment However, such a task does not test the habitual placement of a concept in the referent position of a comparison. In this study, participants judged the similarity between the self and person prototypes in response to linguistic (forced directional) queries or to spatial (nonforced) queries in which the self was positioned above or below the person concept Participants also rated pairs of familiar and unfamiliar countries in a similar manner, to replicate and extend the work of Tversky (1977) Expected asymmetries were observed in forced comparisons. The self and the familiar country were seen as more similar to other people and less familiar countries, respectively, when the former concepts served as the referent of a comparison than when they served as the subject Asymmetries were not observed in the nonforced conditions, and mean similarity in these conditions was of the same magnitude as in the forced condition in which the more familiar stimulus was the referent of the comparison. This result provides the first direct evidence that the self serves as a habitual referent in similarity judgments  相似文献

Holland's theory of congruence of work environments was examined by analyzing the career redirection of 62 men of managerial and professional level who changed occupations between the ages of 33 and 54. Three-letter personality codes for each subject were obtained by administering the Strong-Campbell Interest Inventory. Dictionary of Occupational Titles codes for first and second occupation were obtained and then translated into Holland codes. These were compared to the personality code for each man to determine whether the first or second job was more congruent. It was found that 26 men changed to careers more congruent with their personality, 25 to careers less congruent, and 11 made no change. The results of the study do not lend support to Holland's theory, probably because of the imprecision of DOT categories for research purposes. The need for a more reliable means for coding work environments is discussed.  相似文献

Cases of sexual abuse of children are being reported in increasing numbers. A large percentage of child sexual abuse occurs in or around the home. Family members, family friends, or known adults are most often the offenders. There are certain family factors likely to be operating in a child's sexual abuse and these factors must be explored with all family members. Sexual abuse can have many disturbing consequences for the child and the family. A counseling approach should be to help an abused child and the offender feel that they are still worthwhile individuals. Underlying issues in the family should also be explored. Paula Slager-Jorné is director of training at the Children's Center in Detroit, Michigan.  相似文献

Murray Sidman's contributions to the science of behavior span many areas including avoidance behavior, coercion and its effects, stimulus control, errorless learning, programmed learning, stimulus equivalence, and single-subject methodology. He was also a great mentor to many and helped shape the discipline we now call behavior analysis. In this memoriam, we briefly highlight his scholarly legacy and share some personal anecdotes.  相似文献
