Moral judgments, emotions and the utilitarian brain

The investigation of the neural and cognitive mechanisms underlying the moral mind is of paramount importance for understanding complex human behaviors, from altruism to antisocial acts. A new study on patients with prefrontal damage provides key insights on the neurobiology of moral judgment and raises new questions on the mechanisms by which reason and emotion contribute to moral cognition.     

Is the attribution of cultural differences to minorities an expression of racial prejudice?

The social psychological literature considers two main perspectives on the study of perceived cultural differences between majorities and minorities: one proposes that perception of cultural differences is an antecedent of prejudice and another states that the attribution of cultural differences to minorities is already a hidden expression of racial prejudice. This paper offers further support to this latter perspective. One hundred and ninety-four participants answered a questionnaire measuring (1) general racist belief; (2) cultural differences attributed to Black people (hetero-ethnicization); (3) the asymmetric attribution of secondary and primary emotions to the in-group and to Black people (infra-humanization); (4) the asymmetric attribution of natural and cultural traits to in-group members and to Black people (ontologization); and (5) negative evaluation of this social category. The general racist belief scale was not anchored in a specific group and measured the belief in the inferiority of certain social groups or peoples based on biological or cultural factors. Relationships between the scales were analysed through a set of Structural Equation Models. According to the predictions, results showed that the attribution of cultural differences is a dimension of prejudice. Results also showed that attribution of cultural differences, negative evaluation of Black people, ontologization, and infra-humanization were different dimensions of a common latent factor that can be identified as racial prejudice; and that prejudice was predicted by general racist belief. Results are discussed in the light of the study of the impact of perceived cultural differences on intergroup relations and in the light of the "new racism" approaches.     

Role of the Disease in the Psychological Impact of Pre-Symptomatic Testing for SCA2 and FAP ATTRV30M: Experience with the Disease, Kinship and Gender of the Transmitting Parent

To identify possible factors affecting the psychological impact of pre-symptomatic testing for spinocerebellar ataxia type 2 (SCA2) and familial amyloid polyneuropathy (FAP ATTRV30M), we studied (1) the effect of previous experience with the disease in the family, (2) kinship with the closest affected relative and (3) gender of affected parent, when adapting to test results; as well as (4) differences in the course of psychological wellbeing in 63 subjects ( 28 at-risk for FAP ATTRV30M, and 35 at risk for SCA2), who pursued predictive testing for these diseases, in Cuba and in Portugal. Our research shows that individuals with little or no experience with the disease in their family exhibited more anxiety; at-risk subjects for SCA2 or FAP ATTRV30M who had a first degree relative with the disease showed lower levels of anxiety and depression during pre-symptomatic testing. Also those with an affected mother had lower levels of depression, either immediately, or one year after receipt of test results. Adaptation to pre-symptomatic testing results differed for subjects at-risk for the two different conditions. Unlike the FAP ATTRV30M families, carriers for SCA2 reported pathological levels of depression immediately after-testing (3 weeks), although those levels had returned to normal levels at 6 months. Subjects at-risk for FAP ATTRV30M tended to have less anxiety than those tested for SCA2, at the one-year follow-up. Overall, depression levels improved over time, while anxiety remained more constant. A longer awareness of the disease in the family, closer kinship, and a transmitting mother all lessened the impact of pre-symptomatic testing, as expressed by the post-test levels of anxiety and depression.     

非英语专业大学生CET4成绩影响因素的结构模型

以501名参加过CET4的非英语专业大学生为研究对象,通过英语自我效能感问卷（ESEQ）、英语学习焦虑量表（ELAS）和英语学习策略量表（ELSI）的测量,探讨CET4成绩与其主要影响因素性别、英语自我效能感、英语学习焦虑和英语学习策略之间的结构关系模型。结果显示：（1）非英语专业大学生的英语学习焦虑存在显著的性别差异（女生低于男生）;（2）性别除与英语学习策略不存在直接路径作用外,与CET4成绩、英语自我效能感、英语学习焦虑间均存在直接路径作用;（3）英语学习焦虑对CET4成绩既存在直接路径作用,又通过英语自我效能感、英语学习策略和英语自我效能感的中介产生问接路径作用;（4）英语学习策略仅通过英语自我效能感的中介对CET4成绩产生间接路径作用。研究还表明英语自我效能感在CET4成绩影响因素的结构模型中起着瓶颈作用。     

Community-Based Interventions to Reduce Low Income, African American Women's Risk of Sexually Transmitted Diseases: A Randomized Controlled Trial of Three Theoretical Models

A community-based sample of disadvantaged African American women (n = 445) was recruited to participate in 1 of 3 theoretically driven experimental interventions based on either the theory of gender and power, social learning theory, or cognitive behavioral theory. Intervention outcomes were compared with a waiting list control condition. From baseline to postintervention, women in the experimental interventions showed differential change on cognitive indices (knowledge and attitudes) and skill acquisition (partner negotiation skills, correct condom application, lubricant selection, and information-provision to social networks) whereas control participants were unchanged. Women in the 3 experimental interventions also completed follow-up assessments for 1 year following the interventions. In all 3 experimental conditions, condom use increased relative to the control group and there were no differences between the experimental interventions. Women who participated in one of the theoretically grounded interventions continued to increase condom use over the following year. Women entering new relationships reported significantly more condom use than did women who remained in ongoing relationships. The findings suggest that intervention models that have proven effective for women who engage in high-risk behavior may be less effective for women in established relationships for whom risk is primarily derived from the extrarelationship behavior of their partners.     

The formation of structurally relevant units in artificial grammar learning

A total of 78 adult participants were asked to read a sample of strings generated by a finite state grammar and, immediately after reading each string, to mark the natural segmentation positions with a slash bar. They repeated the same task after a phase of familiarization with the material, which consisted, depending on the group involved, of learning items by rote, performing a shortterm matching task, or searching for the rules of the grammar. Participants formed the same number of cognitive units before and after the training phase, thus indicating that they did not tend to form increasingly large units. However, the number of different units reliably decreased, whatever the task that participants had performed during familiarization. This result indicates that segmentation was increasingly consistent with the structure of the grammar. A theoretical account of this phenomenon, based on ubiquitous principles of associative memory and learning, is proposed. This account is supported by the ability of a computer model implementing those principles, PARSER, to reproduce the observed pattern of results. The implications of this study for developmental theories aimed at accounting for how children become able to parse sensory input into physically and linguistically relevant units are discussed.     

Verbal working memory and on-line syntactic processing: Evidence from self-paced listening

Two experiments investigated the relationship between performance on standard tests of verbal working-memory and the on-line construction of syntactic form. In Experiment 1, working-memory was measured in 100 college students on a version of the Daneman and Carpenter (1980) reading-span task, and online syntactic processing was assessed using a self-paced listening task with four sentence types. In Experiment 2, working-memory was measured in 48 college students on two versions of the reading-span task and two other tests of verbal working-memory, and on-line syntactic processing was assessed using the self-paced listening task with an additional sentence type. In both experiments, there was no relationship between working-memory capacity and the increase in processing time seen for the on-line construction of syntactic form for either syntactically more complex or syntactically simpler sentences. The results indicate that the capacity of the working-memory system that is measured by standard working-memory tests does not determine the efficiency of on-line syntactic processing. They are consistent with the view that the working-memory system used for parsing is at least partially separate from that measured by traditional measures of working-memory capacity.     

Visual space perception and visually directed action.

The results of two types of experiments are reported. In 1 type, Ss matched depth intervals on the ground plane that appeared equal to frontal intervals at the same distance. The depth intervals had to be made considerably larger than the frontal intervals to appear equal in length, with this physical inequality of equal-appearing intervals increasing with egocentric distance of the intervals (4 m-12 m). In the other type of experiment, Ss viewed targets lying on the ground plane and then, with eyes closed, attempted either to walk directly to their locations or to point continuously toward them while walking along paths that passed off to the side. Performance was quite accurate in both motoric tasks, indicating that the distortion in the mapping from physical to visual space evident in the visual matching task does not manifest itself in the visually open-loop motoric tasks.
