The author uses the metaphor of mapping to illuminate a structural feature of racist thought, locating the degraded object along vertical and horizontal axes. These axes establish coordinates of hierarchy and of distance. With the coordinates in place, racist thought begins to seem grounded in natural processes. The other's identity becomes consolidated, and parochialism results. The use of this kind of mapping is illustrated via two patient vignettes. The author presents Freud's (1905, 1927) views in relation to such a "mapping" process, as well as Adorno's (1951) and Baldwin's (1965). Finally, the author conceptualizes the crucial status of primitivity in the workings of racist thought. 相似文献
The octave illusion occurs when each ear receives a sequence of tones alternating by 1 octave but with the high and low tones in different ears. Most listeners perceive these stimuli as a high pitch in one ear alternating with a low pitch in the other ear. D. Deutsch and P. L. Roll (1976) interpreted this phenomenon as evidence for a what-where division of auditory processing caused by sequential interactions between the tones. They argued that the pitch follows the frequency presented to the dominant ear but is lateralized toward the higher frequency component. This model was examined in 4 experiments. Results indicate that the perceived pitch approximates the fundamental frequency and that the illusion does not depend on sequential interactions. The octave illusion may arise from an interaction between dichotic fusion and binaural diplacusis rather than from suppression as proposed by Deutsch. 相似文献
The association between attachment and school-related cognitive functioning was longitudinally examined for a French Canadian sample of 108 school-age children. The affective quality of mother-child interaction patterns, child cognitive engagement, and quality of child attachment to mother were evaluated during a laboratory visit that included a separation-reunion procedure occurring when the children were approximately 6 years of age. Children's mastery motivation and academic performance were assessed 2 years later (at age 8). Analyses indicated that secure children had higher scores than their insecure peers on communication, cognitive engagement, and mastery motivation. Controlling children were at greatest risk for school underachievement, with the poorest performance on all measures except mastery motivation. Avoidant and ambivalent children were lowest on mastery motivation. Results of mediational analyses support the salience of mother-child interactional processes and child cognitive engagement at school age in explaining relations between attachment and cognitive functioning in school. 相似文献
This paper obtains the weak completeness and decidability results for standard systems of modal logic using models built from
formulas themselves. This line of work began with Fine (Notre Dame J. Form. Log. 16:229–237, 1975). There are two ways in
which our work advances on that paper: First, the definition of our models is mainly based on the relation Kozen and Parikh
used in their proof of the completeness of PDL, see (Theor. Comp. Sci. 113–118, 1981). The point is to develop a general model-construction
method based on this definition. We do this and thereby obtain the completeness of most of the standard modal systems, and
in addition apply the method to some other systems of interest. None of the results use filtration, but in our final section
we explore the connection. 相似文献
Few studies have been carried out on emerging adults’ friendships and on their developmental roots. Research suggests that in adolescence, both attachment to parents and attachment to peers play a role in future socio-emotional development. The aim of the present study was to compare attachment in these two types of relationships in adolescence according to gender and test whether they respectively predicted the perception of best friendship in early adulthood. A sample of 83 participants (49 girls) was seen in early adolescence (M?=?13.66 years, SD?=?0.64) and 7 years later (mean age?=?21.15 years, SD?=?0.83). At T1, participants completed the Inventory of Parent and Peer Attachment, which measures attachment using three subscales (communication, alienation and trust) and one global security score. At T2, they completed the McGill Friendship Questionnaire. Results show that in adolescence, boys report higher security with parents compared to peers (mainly due to better communication), unlike girls who obtain higher scores with peers. Longitudinal findings reveal that alienation in the relation with parents is what best predicts friendship quality in early adulthood. These findings underline the specific internal working models at play in socio-emotional development and the way gender differences evolve from adolescence to early adulthood.
Animal personalities have been demonstrated for almost 200 species, with stable dimensions of responses (aggressive to fearful; shy to bold) across contexts and with a heritable basis to these traits. As a long-lived and highly social species, elephants (Loxodonta africana) were expected to demonstrate complex dimensions to individual characteristics or personalities, which would be obvious to human observers and validated by behavioral observations. We used principal-components analysis of ratings on 26 behavioral adjectives applied to one social unit, coded as the EB family, which has been observed for 38 years. Eleven adult females were rated by four observers and found to have individually variable traits on four dimensions described by principal-components analysis. The first component was associated with effective and confident family leadership. Component 2 was age-related, and defined by playfulness, exploration and high levels of activity, suggesting both an experience and an age-related element to its structure. Component 3 represented gentleness and at its other extreme, aggression, and Component 4 was related to constancy (predictability and popularity), with both of these latter components reflecting social integration. Leadership among elephant females represents the successful negotiation among individual interests, and our components were related to a capacity to affect the behavior of others in the absence of aggressive dominance. The family matriarch, Echo, was high on elements associated with leadership. The importance of the matriarch in this family's success suggests that elements of personality may underlie interfamilial variation in long-term survival and reproduction.
