Abstract

The present study tested a model in which the perceived incompatibility of ethnic Russian and regional North Caucasian identities mediates the relationship between perceived discrimination and acculturation strategies in two generations of ethnic Russian minority members living in the Kabardino-Balkar Republic, North Caucasus, Russian Federation. Two identities might be perceived incompatible when they represent conflicting sets of norms and values and the two communities may place competing demands on individual commitment and loyalty. We sampled 105 dyads from ethnic Russian families (youth: M = 18 years, SD = 2.35, 48.6% female; parents: M = 43 years, SD = 6.97, 68.6% female). The questionnaire included measures of perceived discrimination, perceived identity incompatibility, and acculturation strategies. The results of multigroup path analysis showed that the perceived identity incompatibility mediated the relationship between perceived discrimination and two strategies, aimed at culture maintenance (integration and separation) in both generations. Identity incompatibility is regarded as a psychological mechanism that explains the impact of perceived discrimination on minority acculturation preferences in a multicultural region.  相似文献

Perception and Emotion: How We Recognize Facial Expressions   总被引:2,自引:0,他引:2  
ABSTRACT— Perception and emotion interact, as is borne out by studies of how people recognize emotion from facial expressions. Psychological and neurological research has elucidated the processes, and the brain structures, that participate in facial emotion recognition. Studies have shown that emotional reactions to viewing faces can be very rapid and that these reactions may, in turn, be used to judge the emotion shown in the face. Recent experiments have argued that people actively explore facial expressions in order to recognize the emotion, a mechanism that emphasizes the instrumental nature of social cognition.  相似文献

The Unrecognized Stereotyping and Discrimination Against Singles   总被引:1,自引:0,他引:1  
ABSTRACT— A widespread form of bias has slipped under our cultural and academic radar. People who are single are targets of singlism : negative stereotypes and discrimination. Compared to married or coupled people, who are often described in very positive terms, singles are assumed to be immature, maladjusted, and self-centered. Although the perceived differences between people who have and have not married are large, the actual differences are not. Moreover, there is currently scant recognition that singlism exists, and when singlism is acknowledged, it is often accepted as legitimate.  相似文献

This study examines the explanations and justifications offered by those engaged in selecting housemates. The rationale for the research follows the recent housing demographic, whereby shared living has become increasingly popular among young adults in Western countries. This study sought to address the surprising lacuna in the extant research through the application of discursive psychology to understanding prejudice and discrimination within the context of contemporary social and political sanctions against openly discussing prejudice. Data were drawn from interviews with young New Zealanders aged from early twenties to early thirties who were experienced with house sharing. Detailed results are presented involving discrimination based on age, gender, and ethnicity. The study found that rigid narrow preferences were stated with respect to age, gender was less important, and ethnicity was talked about cautiously, especially if there was the possibility of significant cultural differences or language barriers.  相似文献

In an arbitrary matching-to-sample procedure, two mentally retarded subjects learned conditional discriminations with two sets of stimuli. Each set included a spoken name (N1 or N2), an object (O1 or O2), and a printed symbol (S1 or S2). One subject selected conditionally (a) O1 upon N1, and O2 upon N2, and (b) S1 upon O1, and S2 upon O2. The other subject selected conditionally (a) S1 upon N1, and S2 upon N2, and (b) O1 upon S1, and O2 upon S2. For both subjects, selections of O1 and S1 produced one type of food, F1; selections of O2 and S2 produced a different type of food, F2. Both subjects also learned identity-matching performances, selecting O1, O2, S1, S2, F1, and F2 conditionally upon those stimuli as samples; F1 followed selections of O1, S1, and F1; F2 followed selections of O2, S2, and F2. Matching performances consistent with stimulus class formation involving the names, objects, symbols, and foods were demonstrated on probe trials, even though these performances had not been taught explicitly. Next, new objects, X1 and X2, were presented on identity-matching trials, producing F1 and F2, respectively. Without further training, X1 was selected conditionally upon N1, S1, and O1, and X2 was selected upon N2, S2, and O2. When the contingencies were changed so that selections of X1 and X2 were now followed by F2 and F1, respectively, X2 was selected conditionally upon N1, S1, and O1, and X1 was selected upon N2, S2, and O2. Class membership of X1 and X2 had apparently changed. This study provides evidence that reinforcers may become members of stimulus classes, and that new stimuli may become class members through relations with reinforcers.  相似文献

Pigeons were trained to peck a key on a variable-interval 2-min schedule of food reinforcement. Prior to each session, either 2.0 mg/kg methadone (n = 3), 3.0 mg/kg cocaine (n = 4), or 5.6 mg/kg cocaine (n = 2) was administered. When each pigeon's rate of pecking was stable, a range of doses of the training drug and saline were administered prior to 20-min extinction sessions separated by at least four training sessions. Rate of pecking during these extinction tests was generally an increasing function of dose, with the lowest rates obtained following saline and low doses and the highest rates obtained following doses near the training doses. Dose functions from pigeons trained with 5.6 mg/kg cocaine were steeper than those from pigeons trained with 3.0 mg/kg cocaine. Pigeons trained with methadone or 3.0 mg/kg cocaine were then given discrimination training, in which food reinforcement followed drug administration and 20-min extinction sessions followed saline administration. Rates of pecking under these conditions quickly diverged until near-zero rates were obtained following saline and high rates were obtained following drug. Discrimination training steepened dose functions for the training drugs, and the effects of several other substituted drugs depended on the pharmacology of the training drug. The pigeons trained with 5.6 mg/kg cocaine were tested with d-amphetamine, methadone, and morphine prior to discrimination training. d-Amphetamine increased rates dose dependently, and methadone and morphine did not. The results suggest that discriminative control by methadone and cocaine was established without explicit discrimination training.  相似文献

Four rhesus monkeys were trained to respond on one key when a one-second noise burst was presented through one speaker and to respond on a second key when the noise burst was presented through a second speaker. The acquisition of stimulus control was studied under three conditions, in each of which the relationship between the sound source and the response-key positions varied: an adjacent condition in which the noise burst was presented through the key and a response on this key was reinforced; a reversed-adjacent condition in which the noise burst was presented through one key and responding on the other key was reinforced: and a nonadiacent condition in which responding on the key nearer the sound was reinforced. Under adjacent conditions, stimulus control developed within one or two sessions. Under reversed and nonadjacent conditions, 10 sessions were required for the development of control. The asymptote of correct responding was the same under each condition in all animals.  相似文献

Two different prompting procedures to teach visual and auditory discriminations to autistic children were compared. The first involved presenting an added cue as an extra-stimulus prompt. This required the child to respond to both prompt and training stimulus. The second involved the use of a within-stimulus prompt. This consisted of an exaggeration of the relevant component of the training stimulus and thus did not require that the child respond to multiple cues. The results indicated that (1) children usually failed to learn the discriminations without a prompt, (2) children always failed to learn when the extra-stimulus prompt was employed but usually did learn with the withinstimulus prompt, and (3) these findings were independent of which modality (auditory or visual) was required for the discrimination.  相似文献

Where do equivalence relations come from? One possible answer is that they arise directly from the reinforcement contingency. That is to say, a reinforcement contingency produces two types of outcome: (a) 2‐, 3‐, 4‐, 5‐, or n‐term units of analysis that are known, respectively, as operant reinforcement, simple discrimination, conditional discrimination, second‐order conditional discrimination, and so on; and (b) equivalence relations that consist of ordered pairs of all positive elements that participate in the contingency. This conception of the origin of equivalence relations leads to a number of new and verifiable ways of conceptualizing equivalence relations and, more generally, the stimulus control of operant behavior. The theory is also capable of experimental disproof.  相似文献

In the popular folklore three-score-years-and-ten is treated as a fair innings for people, and thereby serves as an informal reference point for judgements about distributive justice within a community. But length of life alone is an insufficient basis for such judgements - a person's health-related quality-of-life also needs to be taken into account. If one of the objectives of public policy is to reduce inequalities in lifetime health, it will be demonstrated that this is very likely to require systematic discrimination against the older members of a community. The notion of community solidatity will also be tested, because a decision will need to be made as to whether the same fair innings applies to all members of the community, or whether some are entitled to more than others. The strength of the fair innings principle is that it brings these issues to the fore in a systematic way which should ais their resolition in a practical context.  相似文献
