Understanding the perception of multiracial persons is increasingly important in today's diverse society. The present research investigated the process of categorizing multiracial persons as “Multiracial.” We hypothesized that perceivers would make fewer Multiracial categorizations of multiracials and that these categorizations would take longer than monoracial categorizations. We found support for these hypotheses across six experiments. Experiment 1 demonstrated that perceivers did not categorize morphed Black–White faces as Multiracial with the same frequency with which they categorized Black and White faces as Black and White (respectively), and that categorizations of multiracials as Multiracial took longer than monoracial categorizations. Experiment 2 replicated and extended these effects to real Black–White faces. Experiment 3 showed that these findings generalized to Asian–White faces. We used pixel variance analysis to show that these effects were not due to increased variance among Multiracial faces. The image analysis showed that the Black–White morphs and real biracials were actually less varied than either the Black or White sets of faces. Experiments 4 and 5 demonstrated that cognitive load and time constraints detrimentally affected multiracial, but not monoracial, categorizations. Experiment 6 showed that imbuing monoracial categories with importance decreases the use of the Multiracial category. Implications of these findings for understanding perceptions of multiracial persons are discussed.  相似文献

The coincidence of historical trends in youth antisocial behavior and change in family demographics has led to speculation of a causal link, possibly mediated by declining quality of parenting and parent–child relationships. No study to date has directly assessed whether and how parenting and parent–child relationships have changed. Two national samples of English adolescents aged 16–17 years in 1986 (N = 4,524 adolescents, 7,120 parents) and 2006 (N = 716 adolescents, 734 parents) were compared using identical questionnaire assessments. Youth-reported parental monitoring, expectations, and parent–child quality time increased between 1986 and 2006. Ratings of parental interest did not change. Parenting differences between affluent and disadvantaged families narrowed over time. There was thus little evidence of a decline in quality of parenting for the population as a whole or for disadvantaged subgroups. Parent-reported youth conduct problems showed a modest increase between 1986 and 2006. Findings suggested that the increase in youth conduct problems was largely unrelated to observed change in parent–child relationships.  相似文献

This study looked at cumulative lifetime estrogen exposure, as estimated with a mathematical index (Index of Cumulative Estrogen Exposure (ICEE)) that included variables (length of time on estrogen therapy, age at menarche and menopause, postmenopausal body mass index, time since menopause, nulliparity and duration of breastfeeding) known to influence estrogen levels across the life span, and performance on prospective and retrospective memory measures in a group of 50 postmenopausal women (mean age=69.3years) who, if they were current or former users of estrogen therapy, had started therapy within 5years of menopause. The ICEE was found to be a significant predictor of performance on the Prospective Memory task (F(1)=4.21, p=.046, η(p)(2)=.084). No significant relationship was noted between the ICEE and performance on measures of retrospective memory. The results suggest that the level of cumulative lifetime exposure to estrogen a woman has influences her prospective memory performance later in life and that the influence of reproductive and biological markers of endogenous estrogen exposure are relevant factors to consider when studying the effect of estrogen therapy on cognitive functioning in postmenopausal women. In addition, the finding that performance on a measure of prospective memory, but not performance on measures of retrospective memory, was associated with the ICEE adds further support to the theory that the frontal cortex may be especially sensitive to estrogen.  相似文献

We explored and compared rates of youth diagnosed with oppositional defiant disorder (ODD) at entry into three broad program types, home-based care, foster care, and residential care. We also explored factors other than an ODD diagnosis that could be associated with program placement, and compared the presence of these factors in youth with and without an ODD diagnosis. Analyses were conducted using data from an ongoing, private-agency led, outcome measurement project. Programs were grouped into low (home-based), moderate (foster), or high (residential) categories, based upon levels of supervision and structure provided. A sample of 9,564 youth admitted into care between years 2005 and 2007 was used. Results suggested the following rates of ODD: 14.2 % overall; 7.9 % for low level programs; 5.3 % for moderate level programs; 21.1 % for high level programs. Rates were significantly different by program level (p ≤ 0.001). Sixty of 65 additional risk factors were also significantly associated with placement by level of program. No risk factors were unique to youth with ODD. Of the significant factors for youth with ODD, 4 were particularly strong: Classification as a child in need of services (CHINS), history of neglect, verbal aggression, and truancy. Youth classified as CHINS and with substantiated or suspected neglect were more likely placed into a moderate level program. Youth with verbal aggression or truancy were more likely placed into a high level program. Results suggested many factors are considered at program entry. Given the potential for poor prognosis and social costs of ODD, results support an individualized approach to placement determinations, with increased attention to symptoms of ODD and associated features at program entry.  相似文献

Three main ideological stances exist regarding sex work issues: abolitionism, sex-positive feminism, and decriminalization. We argue for decriminalization based on decades of research results. Research on female sex workers is most often done through feminist theory and focus on gender relationships and on the experience of oppression and/or agency. Such studies examine the motivations to do sex work, the experience of being objectified, the stigma related to sex work, and, finally, the impact of this kind of work on self-esteem, on couple relationships, and on social relationships. Research on male sex workers examines power dynamics, representations of masculinity, self-perception, and the socioeconomic conditions that lead to sex work and influence safe-sex practices. Usually, feminist approaches do not take the experiences of male sex workers into account. However, taking these experiences into consideration would give a broader perspective to the understanding of sex work, as the experiences of male sex workers show many aspects similar to those of female sex workers. We contend that a woman’s sexual experience has been socially constructed as being part of her identity, in such a way that she becomes socially devalued whenever she does not comply to norms, thus making sex work a ‘degrading’ experience even though it is not intrinsically so.  相似文献

The ability to accurately assess credibility is important in countless situations, including many in which individuals being assessed are not speaking their native language. There is reason to believe that native and non‐native speakers may behave differently when lying and that detectors may have a bias to believe non‐native speakers are lying. However, very little is known about detecting deception in non‐native speakers, and the few existing studies have not resulted in consistent findings. The current research compared the ability to detect lies and truths in native speakers with that in non‐native speakers and looked at differences in the cues displayed via the Psychologically Based Credibility Assessment Tool. Results from two samples with different demographic characteristics and backgrounds indicated that there was a bias to believe that non‐native speakers were lying. These results may have implications regarding the use of interpreters in settings where credibility is being assessed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

In this article, we introduce a preliminary, neurobiologically informed model of group therapy that links the timing and nature of specific group interventions with hypothesized changing neurobiological needs of the group. We suggest that the observed phases of group development reflect an underlying reorganization of neuronal circuitry that occurs as members progress through a hierarchically organized treatment, and that this reorganization involves the integration and homeostatic rebalancing of subcortical and neural networks. Our preliminary Dynamic Relational Model suggests that an understanding of the neurobiological processes involved in group development may help inform and direct effective group-based psychotherapy interventions.  相似文献

The AX-continuous performance task (AX-CPT) and dot pattern expectancy (DPX) are the predominant cognitive paradigms used to assess the relative utilization of proactive versus reactive cognitive control. Experimental parameters vary widely between studies and systematically between different modalities (i.e., fMRI vs. EEG) with unknown consequences for the implementation of control. This meta-analytic review systematically surveyed these bodies of literature (k = 43, 73 data points) to resolve how cue–probe delay knowledge, delay length, and trial set count modulate the preferential use of proactive versus reactive control. In healthy young adults, delay knowledge and increasing trial set count each bias participants toward greater proactive control. Further, the interaction of delay knowledge and trial set count accounts for ~40% of variability in proactive/reactive control performance. As trial count varies reliably between experimental modalities, it is critical to understand how these parameters activate distinct cognitive processes and tap into different neural mechanisms for control. Subgroup analyses revealed important distinctions from our results in healthy young adults. Healthy, slightly older adults (ages 30–45 years) performed more reactively compared to healthy young adults. In addition, participants with schizophrenia showed evidence of more proactive control as trial set count increased. In light of this meta-analytic review, we conclude that delay knowledge and trial set length are important parameters to account for in the assessment of proactive versus reactive control. More broadly, this metaregression provides strong evidence that cognitive control becomes more reactive when timing demands are not known, and that both healthy persons and persons with schizophrenia shift toward proactive control with increasing repetitions of a task set.  相似文献

Reading is a complex process that includes the integration of information about letters (graphemes) and sounds (phonemes). In many circumstances, such as noisy environments, response inhibition is an additional factor that plays a marked role in successful oral reading. Response inhibition can take the form of task relevant inhibition (i.e., foils in a go/no-go task) and task irrelevant inhibition (i.e., distractor information). Here we investigated task relevant inhibition by having participants (N?=?30) take part in two tasks: go/no-go naming with nonwords foils (GNG-NW) and go/no-go naming with pseudohomophones foils (GNG-PH). Also, we investigated the addition of task irrelevant inhibition by having participants (N?=?28) take part in two tasks: GNG-NW?+?information masking and GNG-PH?+?information masking. We provide evidence that during a task relevant inhibition task, sub-word sound level information can be successfully inhibited, as evidenced by comparable response times for regular words and exception words, provided the foils do not contain familiar sound-based information (GNG-NW). In contrast, regular words were read aloud faster than exception words in a GNG-PH task, indicating that sub-word level interference occurs when the foils contain familiar sound-based information. The addition of task irrelevant inhibition (i.e., information masking at the phoneme level), served to increase response time overall, but did not impact the pattern of response times between regular words and exception words. Together these findings provide useful information regarding the role of response inhibition in word recognition and may be useful in computational models of word recognition and future work may benefit from accounting for the effects outlined in this paper.  相似文献

Synthetic biology is an emerging technology that asks for inclusive reflection on how people frame the field. To unravel how we can facilitate such reflection, this study evaluates the Frame Reflection Lab (FRL). Building upon playfulness design principles, the FRL comprises a workshop with video-narratives and co-creative group exercises. We studied how the FRL facilitated frame reflection by organizing workshops with various student groups. Analysis of 12 group conversations and 158 mini-exit surveys yielded patterns in first-order reflection (problem analysis and solution finding in reflection on the development of synthetic biology as a field) as well as patterns in second-order reflection (reflection on values and assumptions underlying the first-order reflection). Also patterns in participants’ (re)framing of synthetic biology could be induced; participants’ viewpoints converged to some extent, yet with openness to individual viewpoint differences. Although the FRL method fortified the reflection processes of participants, the narratives and the workshop’s flexible format could inhibit the reflection too. Therefore, we advise designers of future frame reflection methods to apply stronger conversational facilitation and narratives of slightly mysterious yet identifiable narrators, in case e.g. video-narratives are created and used to scaffold the reflection process. Nevertheless, we argue that the use of a playful frame reflection method like the FRL could function well as (1) a step to precede more application-specific deliberation or decision-making on synthetic biology and as (2) a method for the collection of contemporary citizen viewpoints plus rationales underlying these, for the further (societally) responsible development of the emerging field.  相似文献
