Using closely spaced microelectrode penetrations, we have mapped the representation of the visual field and of several functional response properties on the surface of cat area 18. The representation of the visual field was anisotropic, with the magnification factor for vertical visual space being about 2-5 times greater than that for horizontal. The topographic anisotropy was paralleled by an ...

Three studies using exploratory and confirmatory factor analyses provided consistent evidence for a three-factor model of the social dominance orientation (SDO) in Mainland China. Support for exclusionism, which was not found in previous research, emerged as an independent SDO factor (Studies 1, 2, and 3). In Study 2, this factor predicted SDO difference between a high status group (managers) a...

under the title \Models of Ocular Dominance and Orientation Columns." Reused by permission. ABSTRACT The formation of ocular dominance and orientation columns in the mammalian visual cortex is brieey reviewed. Correlation-based models for their development are then discussed, beginning with the models of Von der Malsburg. For the case of semi-linear models, model behavior is well understood: co...

Three studies were conducted to explore the relationship between social dominance orientation (SDO) and John Henryism (JH). Each study was framed using an intersectionality perspective which predicted that specific combinations of social identities would impact endorsement of SDO and JH in unique ways. We hypothesized that upper-class non-Whites would be higher in SDO and lower in JH than any o...

Research on intergroup ideologies (colorblindness, multiculturalism) has increased our understanding of intergroup attitudes. This article reports empirical tests of the relation between a newly studied ideology, polyculturalism (ideology focusing on interactions and connections among racial/ethnic groups), and intergroup attitudes. Across four studies (with racially/ethnically diverse U.S. und...

1. Quantitative analyses of orientation specificity and ocular dominance were carried out in striate cortex of the rhesus monkey. 2. Sharpness of orientation selectivity was greater for simple (S type) than for complex (CX type) cells. CX-type cells became more broadly tuned in the deeper cortical layers: S-type cells were equally well tuned throughout the cortex. 3. Sharpness of orientation se...

BURGOON AND HER COLLEAGUES have identified seven dimensions of communication: dominance-submission, emotional arousal, composure, similarity, formality, task versus social orientation, and intimacy (Burgoon, Buller, Hale, & DeTurck, 1984; Burgoon & Hale, 1984). Intimacy is the broadest and most often studied dimension; it includes the themes of trust, depth, affection, intensity, and receptivit...
