Although a number of theoretical accounts of proactive interference (PI) in episodic memory have been proposed, existing empirical evidence does not support conclusively a single view yet. In two experiments we tested the predictions of the temporal discrimination theory of PI against alternative accounts by manipulating the presentation schedule of study materials (lists blocked by category vs. interleaved). In line with the temporal discrimination theory, we observed a clear buildup of (and release from) PI in the blocked condition, in which all the lists of the same category were presented sequentially. In the interleaved condition, with alternating lists of different categories, a more gradual and smoother buildup of PI was observed. When participants were left free to choose their presentation schedule, they spontaneously adopted an interleaved schedule, resulting again in more gradual PI. After longer delays, we observed recency effects at the list level in overall recall and, in the blocked condition, PI-related effects. The overall pattern of findings agrees with the predictions of the temporal discrimination theory of PI, complemented with categorical processing of list items, but not with alternative accounts, shedding light on the dynamics and underpinnings of PI under diverse presentation schedules and over different time scales.  相似文献

While trauma is, by definition, a necessary precursor of posttraumatic growth, other aspects of individuals’ life experiences affect their ability to cope with trauma, foster resilience, and grow following adversity. Most research on posttraumatic growth overlooks the accumulation of trauma and sub-trauma stressors as possible predictors of growth. In addition, most research on cumulative adversity omits all but the most extreme examples of discrimination and sexual harassment stressors. This exploratory study of 46 university students with trauma histories used measures of posttraumatic growth, trauma, major (sub-trauma) life events, chronic stressors, sexual harassment, and discrimination to examine the relationship between cumulative adversity and the development of posttraumatic growth. We found that cumulative adversity is positively correlated with posttraumatic growth, and that there are important relationships between gender, race, and cumulative adversity. A hypothesized curvilinear relationship between cumulative adversity and posttraumatic growth was not supported. These findings suggest that successfully coping with some amount of sub-trauma adversity may facilitate the development of posttraumatic growth. Additionally, sexual harassment and discrimination were closely linked to the number of chronic stressors; thus, they need to be included in measures of cumulative adversity to more fully represent the experiences of marginalized groups.  相似文献

Racial discrimination has detrimental effects on ethnic minority adolescents' development. Guided by the integrative model of minority children's competencies and the bioecological model, the current study examined how family and peer cultural socialization independently and conjointly buffered the detrimental effects of discrimination on ethnic minority adolescents' academic and socio emotional adjustment. Using short-term longitudinal data from 245 eighth graders (87% Latinx, 51% female), results suggested that the moderating roles of cultural socialisation operated differently for academic and socioemotional outcomes. Specifically, the three-way interaction results indicated that family and peer cultural socializations appeared to be protective for adolescents' school engagement in the face of discrimination. The significant two-way interaction results revealed that both peer and family cultural socialisation tended to be protective-reactive for socioemotional outcomes, wherein the benefits of cultural socialisation were realised under low-risk but not high-risk conditions for depressive symptoms. Our study provides a nuanced understanding of the moderating roles of cultural socialisation in the links between discrimination and adolescents' well-being, and it highlights the importance of considering cultural socialisation from multiple contexts in examining ethnic minority adolescents' adjustment.  相似文献

Response to name (RTN) is an early developmental milestone, deficits in which are associated with autism spectrum disorder (ASD). This study extends previous research by evaluating an assessment and treatment model for RTN with 13 children with ASD. For all participants, phase 1 was a naturalistic social baseline. The 9 children who did not meet mastery criteria in phase 1 underwent a series of treatment conditions in phase 2. In phase 3, treatment components were removed, and generalization was assessed. Results indicated that tangible reinforcement procedures can produce rapid increases in discriminated RTN, sometimes without prompts. The total number of trials to mastery were reduced in the current study relative to previous research. Results also provide preliminary evidence to suggest that the phase 1 baseline condition may produce distinct patterns of RTN that could be used to predict treatment effects and further reduce trials to mastery in future work.  相似文献

ABSTRACT

Stereotypes of older adults fit a paternalistic pattern, including elevated warmth and lowered competence, yet little effort has been made to elucidate this in an everyday context. This phenomenon was examined with an experimental vignette, in which a woman was offered unnecessary help; specifically, the age (young vs. old) and the independence (accepting vs. declining assistance) of the woman were manipulated. Attributions from a college-age sample toward the woman were examined. In the older conditions, hypotheses were confirmed that participants approved overaccommodative behaviors, endorsed higher warmth and lower competence, and attitudes were modified when the older women contradicted the paternalistic stereotype by declining assistance. That is, competence was modifiable for older women, whereas warmth was not. Implications of these findings as possible evidence of benevolent ageism and the malleability of the Stereotype Content Model are discussed.  相似文献

In research on timing, reinforcers often are assumed to influence discrimination of elapsed time. We asked whether changes in choice used to measure timing arise because of joint control by elapsed time and reinforcers, rather than from the direct modification of control by elapsed time by reinforcers. Pigeons worked on a concurrent-choice task in which 1 response was 9 times more likely to produce a reinforcer, reversing between locations when 19 s had elapsed since the marker event. Across conditions, we manipulated the percentage of reinforcers arranged before the probability reversal from 5 to 95%. These changes in reinforcer percentages altered control by location-based elements of the contingency, but not by time-based elements. Choice was well described by a model that assumes that control by the contingency is weakened by generalization across the time and location of reinforcers, and that these generalizations become more likely at later times since a marker. These findings add to a growing body of research that suggests that reinforcers share the same function as other environmental events in determining how the environment controls behavior.  相似文献

Previous research reports that people organized into newly formed, arbitrary groups (i.e., minimal groups) are on average in-group biased. However, that people on average behave in a certain way does not imply that most people behave that way. Here, I report four studies (n = 224) demonstrating in-group biased average behaviors driven by a minority of about 30% participants. Further, only 14% reported allocating resources in a group-biased manner because they “favored the in-group.” I investigate and discuss how methodological issues related to non-normally distributed data, not taking participants’ intentions into account, and using fixed response matrices can lead to overestimations of how widespread in-group bias is in minimal groups.  相似文献

Muslim Americans are increasingly integrated into American life, displaying high socioeconomic status, political participation, and adherence to American values. However, they are evaluated more negatively than many other racial, ethnic, and religious minorities and are frequent targets of discrimination. This article examines the mismatch between the integration of Muslims and their poor reception. Drawing on theories of cultural fluency and cognitive dissonance, we argue that cultural integration can exacerbate, rather than mitigate, perceived discrimination because integrated individuals are socialized to expect fair treatment and can recognize and decode even subtle forms of discrimination due to high levels of cultural and language fluency. Using three nationally representative surveys and an opt-in, online study of American Muslims between 2007 and 2017, we find that integrated Muslims are consistently more likely than their counterparts to report individual- and group-level societal and political discrimination. The paradox between adopting the host culture and feeling marginalized poses a challenge to the assumption that integration naturally leads to a sense of belonging among minorities, with important implications for liberal democracies.  相似文献

In teaching conditional discriminations to children with autism spectrum disorder (ASD), practitioners may progress from simple to conditional discriminations or may teach conditional discriminations from the onset of instruction. Some research indicates that teaching simple discriminations first may be unnecessary and that teaching may more efficiently focus on conditional discriminations exclusively. This study replicated comparisons of simple-to-conditional and conditional-only discrimination training methods in teaching audio-visual conditional discriminations to Chinese preschoolers with ASD. Results indicated the conditional-only training method appeared to be more efficient in teaching these skills.  相似文献

We investigated whether associations between perceived discrimination (PD), acculturation orientations (desire for culture maintenance and desire for contact), and well‐being (psychological well‐being and life satisfaction) were moderated by group efficacy beliefs—the extent to which group members believe in their ability to achieve social change collectively. We recruited 163 Syrian refugees (M_age = 36.43, SD = 12.68; 88 females and 75 males) from a south‐eastern city in Turkey. PD was negatively associated with desire for culture maintenance and positively associated with desire for contact, indicating an assimilation trend as a response to PD. Both acculturation orientations in turn predicted well‐being positively. However, the ones with higher group efficacy did not experience the detrimental effects of PD on well‐being and indicated a stronger desire for contacting mainstream society. Further conditional indirect effects demonstrated that only among the ones with lower group efficacy, PD was related to lower psychological well‐being through reduced culture maintenance. Findings indicate the critical role of group efficacy beliefs in the understanding of disadvantaged group members' reactions to PD.  相似文献
