We report on the use of our Sniffy program to teach operant conditioning to 900 introductory psychology students. The simulation is designed primarily to teach the principles of shaping and partial reinforcement in an operant chamber. Advanced features are provided for exploring modeling issues and the learning parameters of the model. Students observe the rat’s pretraining behaviors, shape barpressing, and explore the effects of partial reinforcement schedules on a cumulative record. Any of 30 actions can be trained to occur in specific locations in the Skinner box. This paper summarizes details about the software, interface, and instructional objectives. 相似文献

We present three experiments designed to investigate the role of prosody during sentence processing. The first investigated the question of whether an utterance's prosodic contour influences its comprehension on-line. We spliced the beginning and end portions of direct object and embedded clause sentences and observed the consequent effects on comprehension using a dual-task procedure to measure processing load. Our second experiment sought to determine-whether the constituent structure of these sentences could be reliably predicted using prosodic information. We found that the duration and F0 contour associated with the main-clause verb and the following NP reliably distinguished between the direct object and embedded clause constructions. In the final experiment, we manipulated the duration of the main-clause verb and found that subjects used this information to guide their initial parse during on-line sentence comprehension. The need for a model of sentence processing that addresses the use of prosodic information is discussed.The work reported in this paper was supported in part by NTH grant DC00494. 相似文献

The importance of using culturally sensitive educational materials in HIV-related interventions with racial and ethnic minority groups is widely recognized. However, little empirical research has been conducted to assess the relative effectiveness of different techniques for creating culturally sensitive AIDS educational videos. Two field experiments with three samples of African American adults (N = 174, 173, and 143) were conducted to assess how source characteristics (race of communicator), message characteristics (multicultural message vs. culturally specific message), and audience characteristics (racial distrust and AIDS-related distrust) influence proximate (perceptions of the message's credibility and attractiveness) and distal (AIDS-related attitudes, beliefs, and behavioral intentions) output variables for AIDS educational videos. In Study 1, an AIDS video with a culturally specific message was rated as more credible, more attractive, and of higher quality than was a video with a multicultural message. The multicultural message was rated less favorably when delivered by a White announcer than when the announcer was Black. In Study 2, the same pattern was replicated with a second community sample and a campus-based sample. Study 2 also indicated that a multicultural message might be more effective if delivered in a culturally specific context, namely, after audience members watch a culturally specific video. Minimal changes were observed in distal outcome variables. It is argued that influencing proximate output variables is necessary, though not sufficient, for effecting long-term change in AIDS-related attitudes, beliefs, and behaviors. 相似文献

An observational scale to record aggressive behaviors, defenses, and interventions that occur during a psychotherapy group has been developed. Content and process items were included. The content items focus on the spoken material and are on a continuum of increasing group members' awareness of and responsibility for their anger. The process items are directed to underlying psychodynamic issues on a continuum from avoiding anger, to indirect and then expression of anger. Leader interventions (responses) are also included. The development of the scale, the Aggression Observation Scale for Group Psychotherapy (AOSGP), is described including pilot testing and reliability and validity findings. 相似文献

Intervening effectively with youths at risk from early deprivation, family dysfunction, poverty, abuse, and other factors is a major concern for educational and social service policymakers. Current research suggests that a majority of at-risk youths do not experience drastic outcomes, but many exhibit protective factors that buffer them from negative consequences. Longitudinal studies from Hawaii, the continental United States, and Great Britain have identified several personality, familial, and environmental variables that promote resiliency in youths at risk. This article discusses these variables and provides counselors with an assessment technique and strategies to promote a salutogenesis perspective. 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.

Amendments to the Age-Universal I-E scale, used to measure intrinsic and extrinsic orientations toward religion, are proposed to facilitate the scales' use among both religious and non-religious samples. The original and revised versions of the intrinsic and extrinsic scales were administered to six adult samples from the U.S.A. (N = 156; N = 144), England (N = 135; N = 149) and Norhern Ireland and Republic of Ireland (N = 189; N = 167). Data show in all six samples the percentage of I-E scales completed was greater for the revised version than the original version. In addition, the revised version of the scales demonstrates more satisfactory reliability estimates than the original version. It is suggested that researchers examining intrinsic and extrinsic orientation towards religion may benefit from using the revised version. 相似文献
