Auditory and proprioceptive spatial impairments in blind children and adults

It is not clear what role visual information plays in the development of space perception. It has previously been shown that in absence of vision, both the ability to judge orientation in the haptic modality and bisect intervals in the auditory modality are severely compromised (Gori, Sandini, Martinoli & Burr, 2010; Gori, Sandini, Martinoli & Burr, 2014). Here we report for the first time also a strong deficit in proprioceptive reproduction and audio distance evaluation in early blind children and adults. Interestingly, the deficit is not present in a small group of adults with acquired visual disability. Our results support the idea that in absence of vision the audio and proprioceptive spatial representations may be delayed or drastically weakened due to the lack of visual calibration over the auditory and haptic modalities during the critical period of development.     

“清代道藏”——江南蒋元庭本《道藏辑要》之研究

继明代《正统道藏》之后,《道藏辑要》是最重要的道教丛书。《道藏辑要》一书的形成至今仍是个谜,当代学者普遍认为它有三个主要版本:一为彭定求(1645-1719)编原本,二为蒋元庭(1755-1819)增补本,三为贺龙骧、彭瀚然最终修订本。与学者们普遍认可的观点不同,本文力图证明《道藏辑要》实际上只有两个版本(版本二和版本三),而所谓的彭定求本纯属虚构。在对蒋元庭之同代人闵一得(1748/58-1836)的作品进行研究后,我们证实蒋元庭确是《道藏辑要》的编者。在闵一得的作品中,我们还可以发现《道藏辑要》在江南地区与"吕洞宾崇拜"有关之道教社团中的影响;在巴黎藏本《道藏辑要》(这一版本与藏书家丁福保编制目录之版本十分近似)中,这种影响的痕迹更是十分明显。在此发现的基础上,本文力图开辟新的研究领域,使读者可以更好地了解《道藏辑要》的复杂文本历史,以及它在推动清代道教纯粹远景及扶鸾崇拜中的角色。     

The Perceived Ethnic Discrimination Questionnaire: Development and Preliminary Validation of a Community Version1

This paper describes 2 studies that evaluated a new instrument, the Perceived Ethnic Discrimination Questionnaire‐Community Version (PEDQ‐CV). The PEDQ‐CV can be used across ethnic groups to assess perceived racism or ethnic discrimination. The scales measure several subdimensions of racism, permitting the examination of different forms of this race‐related stressor. The first study evaluated the psychometric properties of the PEDQ‐CV in a large sample of community‐dwelling adults. The second evaluated psychometric properties of a brief version of the PEDQ‐CV, developed for research protocols requiring a shorter administration time. Tests were made of reliability and several forms of construct validity. Both versions of the PEDQ‐CV have good reliability and construct validity. The PEDQ‐CV can facilitate the development of an integrative body of knowledge across different ethnic groups regarding the existence, determinants, and consequences of discrimination.     

The Self-Report Psychopathy Scale and passive avoidance learning: a validation study of race and gender effects

The reliability and validity of the Self-Report Psychopathy Scale (SRPS) was examined in a noninstitutionalized offender sample of mixed gender and race. Adequate alpha coefficients were obtained for the total sample and across gender and race. The SRPS was compared to measures of trait anxiety and passive avoidance errors. SRPS total, primary, and secondary scores were positively and significantly correlated with trait anxiety and passive avoidance (commission) errors, but not omission errors. Employing hierarchical regression models, no anxiety, gender, or ethnic effects were found. Intelligence confounded the relationship between psychopathic traits and passive avoidance errors. Findings provide tentative support of the SRPS as a valid measure of psychopathy.     

A test of whether attributions provide for self-enhancement or self-defense

It is well known that people often make attributions in a way that is favorable to their self-concepts (see R. L. Collins, 1996, for a review). However, it is less clear whether the primary effect is to enhance self-esteem or to defend against the possible loss of self-esteem. The authors performed an experiment to test these possibilities against each other. In a completely between-participants design, participants recalled either a positive behavior or a negative behavior that was performed by themselves or others. They then judged the positivity or negativity of the behavior and made trait attributions about the actor (i.e., himself, herself, or others). The results indicated that although judgments and trait attributions for positive behaviors were similar for the self and for others, judgments and trait attributions for negative behaviors were less negative for the self than they were for others. The authors interpreted these and other findings as supporting a defensive strategy rather than an enhancive strategy.     

Recognition accuracy and reaction time of vocal expressions of emotion by African-American and Euro-American college women

This study examined the relationship of racial group membership and vocal expressions of emotion. Recognition accuracy and reaction time were examined using the Diagnostic Assessment of Nonverbal Accuracy 2 Receptive Paralanguage subtests with 18 young Euro-American and African-American women. Participants listened to Euro-American children and adults speaking a neutral sentence, and identified the emotion as happy, sad, angry, or fearful. Analysis identified a significant effect for race on reaction time. Euro-American participants had faster mean RT than the African-American women for the recognition of vocal expression of emotion portrayed by Euro-Americans. However, no significant differences were found in mean accurate identification between the two groups. The finding of a significant difference in recognition RT but not in accuracy between the stimuli spoken by an adult and a child was unexpected. Both racial groups had faster mean RT in response to vocal expression of emotion by children.     

The association of psychopathic traits with aggression and delinquency in non-referred boys and girls

The current study investigated the association of psychopathic traits with aggression and delinquency in a non-referred sample of boys (n=86) and girls (n=114) in the fifth through ninth grades at two public schools in a large urban area. Psychopathic traits were measured by both teacher- and self-report ratings, whereas aggression and delinquency were assessed through self-report ratings. Self-reported psychopathic traits were associated with both aggression and delinquency and teacher-reported psychopathic traits were associated with higher levels of aggression. There were no clear differences for the callous-unemotional, narcissism, or impulsivity dimensions in their associations with aggression and delinquency. Also, psychopathic traits predicted aggression and delinquency for both boys and girls. The one clear gender difference was in the stronger associations between psychopathic traits and relational aggression for girls.     

Treatment of panic disorder: live therapy vs. self-help via the Internet

A randomized trial was conducted comparing 10 individual weekly sessions of cognitive behaviour therapy for panic disorder (PD) with or without agoraphobia with a 10-module self-help program on the Internet. After confirming the PD diagnosis with an in-person structured clinical interview (SCID) 49 participants were randomized. Overall, the results suggest that Internet-administered self-help plus minimal therapist contact via e-mail can be equally effective as traditional individual cognitive behaviour therapy. Composite within-group effect sizes were high in both groups, while the between-group effect size was small (Cohen's d=16). One-year follow-up confirmed the results, with a within-group effect size of Cohen's d=0.80 for the Internet group and d=0.93 for the live group. The results from this study generally provide evidence to support the continued use and development of Internet-distributed self-help programs.     

Estimating the frequency of events from unnatural categories

We report two experiments about how people estimate the frequency of event properties when they are explicitly (e.g, spinach-GREEN) and implicitly (e.g, spinach) presented. In Experiment 1, verbal reports indicated that, for explicitly presented properties, participants used several retrieval- and impression-based strategies and were relatively accurate. Implicitly presented properties led to off-target retrieval, which brought to mind more instances of nontarget than of target properties and degraded estimates. A third group estimated the frequency of taxonomic categories (e.g., furniture) much as the explicit property group did, suggesting that people can use properties to organize remembered events. In a second experiment, estimation time patterns underscored the results of Experiment 1 and eliminated reactive verbal reports as an explanation. Off-target retrieval was both ineffective and slow.
