精神分裂症对情绪的面部表情加工及其神经机制

综述了近年来关于精神分裂症对情绪面部表情加工损伤的研究,讨论了这种损伤的性质,以及对这种损伤性质的解释,比如它属于一般性还是特异性的损伤,与临床症状以及认知特征之间的关系等。比较分析表明,精神分裂症情绪面部表情知觉损伤,可能兼有面部信息加工障碍和情绪信息知觉困难的特性。另外,介绍了国外关于针对精神分裂症面部表情再认和识别的康复训练研究以及近年来利用事件相关电位（ERPs）和功能磁共振成像（fMRI）等认知神经科学技术进行的神经生理机制研究     

同步与否：婴儿基本面部表情识别的发展特点

面部表情是通过眼部、口部等肌肉动作传递出来的情绪信号。婴儿对面部表情的正确识别是婴儿与外界交流的重要手段,有利于情绪认知的发展。婴儿对基本面部表情识别的发展具有非同步性的特点：对正性效价表情的识别早于负性效价表情,2个月大的婴儿能辨别出正性效价表情,4～6个月大时能辨别出不同的负性效价表情;情绪感知能力的发展早于情绪理解能力,7个月大的婴儿已初步具备情绪感知能力,12个月大的婴儿还不能准确区分不同的负性效价表情所表达的情绪意义。婴儿识别表情受到环境和认知因素的双重影响,反映了基本情绪的激活到情绪图式的形成过程。

社会性发展迟滞大学生的表情加工及其类别知觉

本研究比较了社会性发展迟滞大学生与正常大学生的表情加工,探讨迟滞个体表情加工的特点及可能原因,还验证面部表情类别知觉效应。采用Morph情绪面孔实验发现：除恐惧情绪外,基本表情的强度越大被试对表情的识别越好;但迟滞个体的表情加工速度比正常个体慢,对愤怒的识别也更差;他们辨别混合表情中悲伤、愤怒的类别界线都发生偏移。迟滞个体的表情加工能力不如正常个体,并且对悲伤具有反应偏向,对愤怒存在加工缺陷。     

表情强度对自闭症儿童面部表情识别影响的实验研究

为探寻自闭症儿童在识别低强度（10%,30%）、中强度（40%,60%）和高强度（70%,90%）的愤怒和开心面部表情时,识别情绪类型的既有能力和差异。采用表情标签范式,用E-prime软件在电脑上呈现不同强度的3D合成面部表情刺激,分别对10名自闭症儿童、10名正常发育儿童和10名智障儿童进行了实验研究。结果发现,自闭症儿童在低强度表情时具有面部表情识别障碍,其对不同强度面部表情识别正确率显著低于智障儿童和正常发育儿童;自闭症儿童面部表情识别正确率与面部表情强度呈正相关,面部表情强度越大,自闭症儿童面部表情识别的正确率越高;自闭症儿童对低强度面部表情识别时,对开心表情的识别正确率高于愤怒表情,但是,在中强度和高强度面部表情识别时,存在显著的愤怒优势效应。     

先天性音乐障碍的音高空间表征能力研究

利用音高空间表征任务、心理旋转任务和音高辨别任务,探讨先天性音乐障碍者音高空间表征能力、心理旋转加工能力和音高辨别能力。结果发现：先天性音乐障碍组音高空间表征任务标准差、心理旋转任务错误率和音高辨别任务错误率均显著高于控制组。 这些结果表明先天性音乐障碍并非音乐特异性障碍,而是音乐相关性障碍。     

面部表情的类别知觉及其个体差异

面部表情类别知觉效应是指连续变化的表情在人脑中按照类别表征, 且不同类别的表情之间存在明显的类别界线。介绍了面部表情类别知觉效应的行为和脑电研究范式及基础研究, 综述了攻击性、抑郁症、精神分裂症、社交焦虑等对面部表情类别知觉的影响, 以及面部表情类别知觉的发展研究。综述表明, 类别知觉研究能够揭示不同人群表情知觉类别界线及其偏移情况, 有助于解释相应的社会行为。未来研究应注重对面部表情类别知觉效应的个体差异和神经生理机制的探索。     

中央线索化对听觉障碍人群辨别任务返回抑制的影响

选取一组先天聋被试和与之匹配的听力正常被试,采用线索提示范式考察中央线索化对听觉障碍被试在辨别任务中基于位置返回抑制的影响。实验结果发现,在有中央线索化的任务实验中,听力正常和听觉障碍被试都出现了返回抑制,但是听觉障碍被试消失得比听力正常被试早。无中央线索化的辨别任务实验中,听力正常被试组仅在SOA=650ms时,听觉障碍被试没有发现返回抑制现象。结果表明听觉障碍被试辨别任务的返回抑制更易受中央线索化条件的影响,听障被试的空间注意调节机制更具策略性和有效性。     

Disability, Minority, and Difference

In this paper I develop a characterization of disability according to which disability is in no way a sub-optimal feature. I argue, however, that this conception of disability is compatible with the idea that having a disability is, at least in a restricted sense, a harm. I then go on to argue that construing disability in this way avoids many of the common objections levelled at accounts which claim that disability is not a negative feature.     

The Contribution of Attributional Style to Perceived Disability in Rheumatoid Arthritis: A Longitudinal Study

The current study investigated the influence of general causal attributions on self-reported physical disability over the course of 1 year in a sample of 42 patients with rheumatoid arthritis (RA). Participants completed measures of attributional style, pain, and disability; physician assistants completed objective measures of disability on two occasions, approximately 1 year apart. Results indicated that internal attributions for disease-unrelated negative events assessed at Time 1 were associated with lower perceived physical disability, whereas stable attributions for negative events were associated with greater perceived physical disability 1 year later. These findings are discussed in terms of behavioral and characterological self-blame models, respectively. Implications of our findings for clinical management of RA are also discussed.     

The Influence of Group Size and Stigma Severity on Social Acceptance: The Case of People with Intellectual Disability Moving into Neighbourhoods

Dutch adults from a nationwide Internet panel (N = 426) were asked to imagine that their next‐door neighbours would move out and that people with intellectual disability would move in. Severity of disability and group size were varied to manipulate intergroup threat. These two factors independently influenced social acceptance and a variety of emotional and behavioural measures. In particular, it was found that a large group with severe disability aroused the strongest negative response, whereas a small group with mild disability aroused the weakest negative response. Small groups with a severe disability and large groups with a mild disability aroused similar and intermediate negative responses. Results are discussed in terms of theories of intergroup threat and stigmatisation. Practical implications for predicting the success of de‐institutionalisation and social integration of groups with special needs are addressed. Copyright © 2011 John Wiley & Sons, Ltd.     

The effect of video observation on warmth and competence ratings of individuals with a disability

ObjectivesThis study examined whether a video featuring an adult with a physical disability engaging in either sport, exercise, or an activity of daily living (ADL) can mitigate negative stereotypes of disability held by people without a disability.DesignThis study used a pre-post design, involving three participant groups.MethodsParticipants (n = 212) read a vignette describing an adult with a disability (target). Consistent with the stereotype content model, participants judged the target's warmth and competence. One week later, participants viewed a video of the target participating in sport, exercise, or an ADL and judged the target's warmth and competence.ResultsJudgements of competence but not warmth changed over time. The greatest increases occurred in the sport condition. At follow-up, the typical high warmth low competence stereotype of disability was reversed; the character was judged as being more competent than warm especially in the sport condition.ConclusionVideos of adults with a disability engaging in physical activity, particularly sport, have potential to mitigate negative stereotypes of disability.     

Negative and Positive Disability-related Events and Adjustment of Parents with Acquired Physical Disabilities and of their Adolescent Children

This study merged stress-and-coping research with the social model of disability to describe the most frequently experienced disability-related events experienced by 19 parents with acquired physical disabilities and their adolescent children, and examined the relations between these events, severity of disability, and psychological adjustment. Parents and adolescents reported many more positive than negative disability-related events, although parents reported significantly more negative events than did their children. Frequency of parents’ experienced negative disability-related events correlated significantly with self-reported anxiety, depression, and weaker feelings of parental self-efficacy, with their reports of adolescents’ internalizing and externalizing problems, and with adolescents’ self-reports of depression, anxiety, and lower self-esteem. Frequency of adolescents’ negative disability-related events correlated significantly with self-reported depression and lower self-esteem, and approached significance with self-reported anxiety. There were no significant associations between parents’ positive events and self-reported or adolescent adjustment. Total frequency of adolescents’ positive events correlated significantly with less parent-reported anxiety. There were several significant associations between parental rating of severity of disability and number of physical limitations with their and their children’s adjustment. Implications for understanding the daily effects of parental physical disability on parents and their adolescent children are discussed, and recommendations are suggested for prevention interventions.     

Disability, race/ethnicity and gender: themes of cultural oppression, acts of individual resistance

Community psychologists have called for research on human diversity and interactions between individuals and society with a focus on oppression. This study examines learning disabilities as they co-occur with other sociopolitical minority statuses. We examined dominant cultural narratives of and individual responses to learning disability, race/ethnicity and gender identified by low-income men and women of color with learning disabilities. Our qualitative analysis identified cultural narratives that suggest that: (1a) individuals with learning disabilities are perceived as having an illegitimate impairment and being of lower intellectual ability and unworthy; (1b) having an invisible disability facilitates passing as nondisabled, thereby lessening disability discrimination from within racial/ethnic groups; (1c) having a learning disability detracts from positive gender expectations and exacerbates negative ones; and (1d) gender and racial/ethnic narratives are relevant for individuals with learning disabilities. Our analysis also identified two overarching individual acts of resistance used to thwart internalization of oppressive cultural narratives: (2a) removing self from oppressive environments and (2b) reframing dominant cultural narratives (including discounting the validity of negative messages, using negative narratives for motivation, and engaging in positive self-talk). We discuss findings in relation to extant research and theory and consider implications for research, theory, and practice.     

Predictors of COVID-19 precautionary behaviors to protect people with disabilities

Disability is conceptualized using one of two major frameworks: the medical and the social model of disability. The medical model of disability describes disability as an individual issue in which the appropriate intervention is to remove the disability. The social model of disability describes disability as a social construction in which the appropriate intervention is societal change to increase accessibility. This study drew on models of disability to understand predictors of engagement in COVID-precautionary behavior prior to the vaccine to protect people with disabilities (PWD) from contracting COVID-19. Participants (n = 720) with and without disabilities (n = 77 and n = 633, respectively) completed an online questionnaire measuring disability beliefs, attitudes toward PWD, concerns about PWD contracting COVID-19, and engagement in behavior protecting PWD from contracting COVID-19. Medical model beliefs were negatively associated with behavior. In addition, negative attitudes toward PWD and low concern about PWD contracting COVID-19 fully accounted for the relationship. Social model beliefs were positively associated with behavior. In addition, positive attitudes toward PWD and greater concern about PWD contracting COVID-19 partially explained the relationship. These findings suggest that framing disability as a social construction rather than a medical issue could promote greater public health behavior to protect PWD from contracting COVID.     

Health, wealth, and happiness: financial resources buffer subjective well-being after the onset of a disability

We examined the hypothesis that the relationship between financial status and subjective well-being, typically found to be very small in cross-sectional studies, is moderated by health status. Specifically, we predicted that wealth would buffer well-being after the onset of a disability. Using data from the Health and Retirement Study, a longitudinal study of people at and approaching retirement age, we employed within-subjects analyses to test whether wealth measured prior to the onset of a disability protected participants' well-being from some of the negative effects of a new disability. We found support for this hypothesis: Participants who were above the median in total net worth reported a much smaller decline in well-being after a new disability than did participants who were below the median. We also found some evidence that the buffering effect of wealth faded with time, as below-median participants recovered some of their well-being.     

Interpersonal Reactions to Depression and Physical Disablllty In Dyadic Interactions1

Examined the interpersonal responses of persons engaged in dyadic interactions with confederates who enacted either depressed or socially appropriate roles and appeared either with or without a physical disability. Subject negative evaluations of confederates were indirectly obtained from a thought-listing measure. The overt behaviors of subjects were surreptitiously recorded on videotape and measures of verbal and nonverbal behavior were acquired. Subjects spoke less to the depressed targets and had significantly higher rates of negative evaluations of these persons. In addition, subjects gazed less at the depressed confederates. These effects were not moderated by target physical appearance. Findings are discussed as they relate to social models of depression and the stigmatizing effects of disability.     

Normal and Natural, or Burdensome and Terrible? Women with Spinal Cord Injuries Discuss Ambivalence about Menstruation

Literature on women’s reproductive health experiences after spinal cord injuries (SCI) documents a temporary period of amenorrhea after women’s injuries. However, research is lacking on how women with SCI feel about amenorrhea or menstruation. That is, we do not know the meanings that women with permanent, physical disability ascribe to their experiences of simultaneously “normal” and “abnormal” reproductive processes. Prioritizing a feminist disability perspective and using interview data from a snowball sample of 20 women with SCI in Detroit, Michigan, in the United States, we outline how interviewees are ambivalent (yet also slightly negative) towards menstruation and amenorrhea within the context of their disability, and may be both different from and similar to able-bodied women in their attitudes and experiences as a result.
