本研究旨在考察歧视知觉(包括个体和群体歧视知觉)在社会经济地位和留守儿童社会适应之间的中介作用.542名10~18岁留守儿童参加了本次调查,测量工具包括社会经济地位(三个指标:父母职业,父母受教育程度和家庭经济),个体和群体歧视知觉量表,积极和消极情感量表,自尊量表和问题行为量表.结果发现:(1)留守儿童社会经济地位与其社会适应之间有着显著的正相关;(2)相对于个体歧视知觉,留守儿童群体歧视知觉在家庭社会经济地位和社会适应之间的中介作用更为显著;(3)留守儿童群体歧视知觉中介模型不存在显著的性别差异,但高群体歧视知觉的男生比同类别的女生更容易产生社会适应问题. 相似文献

Whereas many studies have considered the role of attention in prospective timing, fewer have established relations between movement complexity and prospective timing. The present study aims at assessing to what extent motion complexity interferes with prospective timing and at delineating a neuropsychophysical plausible model. We have thus designed a visual paradigm presenting stimuli in sequential pairs (reference comparison interval). Stimuli are motionless or moving according to different complexities, and stimulus complexities are intermixed within each pair. To prevent a possible attention-sharing effect, no concurrent task was required. Our study suggests that movement complexity is a key component of duration perception, and that the relative judgement of durations depends on spatio-temporal features of stimuli. In particular, it shows that movement complexity can bias subjects’ perception and performance, and that subjects detect that comparison intervals are longer than reference before their end. In the discussion, we advocate that the classical internal clock model cannot easily account for our results. Consequently, we propose a model for time perception, based on a parallel processing between comparison interval perception and the reconstruction of the reference duration. 相似文献

Perceptual reorganisation of infants' speech perception has been found from 6 months for consonants and earlier for vowels. Recently, similar reorganisation has been found for lexical tone between 6 and 9 months of age. Given that there is a close relationship between vowels and tones, this study investigates whether the perceptual reorganisation for tone begins earlier than 6 months. Non-tone language English and French infants were tested with the Thai low vs. rising lexical tone contrast, using the stimulus alternating preference procedure. Four- and 6-month-old infants discriminated the lexical tones, and there was no decline in discrimination performance across these ages. However, 9-month-olds failed to discriminate the lexical tones. This particular pattern of decline in nonnative tone discrimination over age indicates that perceptual reorganisation for tone does not parallel the developmentally prior decline observed in vowel perception. The findings converge with previous developmental cross-language findings on tone perception in English-language infants [Mattock, K., & Burnham, D. (2006). Chinese and English infants' tone perception: Evidence for perceptual reorganization. Infancy, 10(3)], and extend them by showing similar perceptual reorganisation for non-tone language infants learning rhythmically different non-tone languages (English and French). 相似文献

The level of racism in Australia against Aboriginal Australians is well documented. This has an extremely detrimental effect on the health and wellbeing of Aboriginal Australians. One part of the solution may be anti‐prejudice strategies, but to date few strategies that include a pre‐test and a post‐test assessment have been conducted in Australia. The present study describes the interventional qualities of a cultural psychology unit at an Australian university. Results indicated that after a 6‐week period, students reported a significant reduction in prejudice, acceptance of false beliefs about Aboriginal Australians, and the perception that Aboriginal Australians unfairly receive preferential or special treatment. The article concludes that cultural psychology units have the potential to be an effective way of developing acceptance of cross‐cultural differences. 相似文献

By definition, all of the stimuli in an equivalence class have to be functionally interchangeable with each other. The present experiment, however, demonstrated that this was not the case when using post-class-formation dual-option response transfer tests. With college students, two 4-node 6-member equivalence classes with nodal structures of A-->B-->C-->D-->E-->F were produced by training AB, BC, CD, DE, and EF. Then, unique responses were trained to the C and D stimuli in each class. The responses trained to C generalized to B and A, while the responses trained to D generalized to E and F. Thus, each 4-node 6-member equivalence class was bifurcated into two 3-member functional classes: A-->B-->C and D-->E-->F, with class membership precisely predicted by nodal structure. A final emergent relations test documented the intactness of the underlying 4-node 6-member equivalence classes. The coexistence of the interchangeability of stimuli in an equivalence class and the bifurcation of such a class in terms of nodal structure was explained in the following manner. The conditional discriminations that are used to establish a class also imposes a nodal structure on the stimuli in the class. Thus, the stimuli in the class acquire two sets of relational properties. If the format of a test trial allows only one response option per class, responding on those trials will be in accordance with class membership and will not express the effects of nodal distance. If the format of a test trial allows more than one response option per class, responding on those trials will be determined by the nodal structure of the class. Thus, the relational properties expressed by the stimuli in an equivalence class are determined by the discriminative function served by the format of a test trial. 相似文献

In Experiment 1, rats were trained in a symbolic delayed matching-to-sample task to discriminate sample stimuli that consisted of sequences of magazine light flashes. The intertrial interval was illuminated by the houselight for Group Light, and it was dark for Group Dark. Retention functions exhibited a choose-many response bias when the delay interval was illuminated by the houselight in both groups, and no consistent response bias when the delay interval was dark. In Experiment 2, rats were trained to discriminate sample stimuli that consisted of sequences of tone bursts. During delay testing, a different tone (i.e., different frequency and location than the sample tone) was present or absent during the delay interval. The retention functions exhibited a significant choose-many bias when tone was present during the delay and a choose-few bias when tone was absent. Asymmetrical retention functions for tone burst and light flash sequences are due to the similarity between the stimulus conditions of the delay interval and the modality of the sequential event being discriminated. These results are consistent with an instructional ambiguity explanation of response biases in memory for number. 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

Muslim Australians represent one of the fastest growing migrant groups in Australia. They are also the group who, after Indigenous Australians, experience the most discrimination. Previous research on the minority stress model confirms a link between such discrimination and mental health. However, in relation to self‐esteem and discrimination, the results are mixed, potentially reflecting whether people reject or identify with prejudiced views of them and also the type of discrimination being measured. To explore this issue further in an Australian context, we asked 49 Australian Muslims to complete Rosenberg's Self‐esteem Scale and the Perceived Religious Discrimination Scale. In support of both the minority stress model and the rejection‐identification model, we found that perceived interpersonal and systemic discrimination accounts for a small but significant variation in self‐esteem. Interpersonal discrimination was negatively related to self‐esteem, and systemic discrimination positively related. The effects of interpersonal discrimination on self‐esteem can guide therapists to interventions that help clients resist internalising discrimination experiences. The effects of institutional discrimination support therapists becoming part of the resistance to and challenging of discrimination and inequality. 相似文献
