Proximal and Distal Predictors of Homophobia: Framing the Multivariate Roots of Outgroup Rejection1

A proximal-distal theoretical framework was developed to examine the multivariate roots of homophobia. Using data from a sample of 288 undergraduates who had participated in a computer-assisted panel study over a three-year period, the effects on homophobia of distal and proximal family factors (e. g., parental education and family environment), distal and proximal individual factors (e. g., personality constructs and current beliefs), and proximal individual-situational factors (e. g., acquaintance with homosexuals) were tested in regression analyses. Both analyses employing sets of variables varying in proximity to the homophobic attitude and hierarchical regression employing variables contributing significantly in each set supported the proposed framework. All sets predicted significantly when regressed separately on homophobia; the sets containing the distal factors contributed most weakly, and the sets containing the proximal factors contributed most strongly. In hierarchical regression analysis, this pattern maintained such that the incremental increase in r² decreased with the addition of each more distal set, with the most distal factors failing to contribute significantly to the prediction. The importance of study findings for attitude change efforts is discussed.

The moral reasoning of juvenile delinquents: A meta-analysis

To test the hypothesized immaturity of juvenile delinquents' moral reasoning, the results of 15 studies of the moral reasoning of juvenile delinquents were integrated quantitatively using meta-analysis. Hedges and Olkin (1985) methods were used to (a) compute effect sizes, (b) test the homogeneity of the obtained effect sizes, and (c) test the statistical significance of the pooled mean effect size. The results supported the hypothesis that the moral reasoning of juvenile delinquents is immature. It was concluded that several other issues are in need of investigation.     

Operate your own World-Wide Web server

Although many researchers wishing to use the World-Wide Web for academic purposes rely on centralized Web services, they should be aware that it is neither expensive nor difficult to operate their own server. Doing so provides research-related benefits such as complete control over their host name and documents provided, the guaranteed ability to execute common gateway interface and server-side include programs, immediate access to their collected data, and the ability to better control who participates in their experiments. This paper surveys Web-server software features likely to be of interest to psychologists and conceptually summarizes their operation and use. The basic steps required to set up a Web server on popular microcomputers are reviewed, and security issues concerning Web-server operation are discussed. An accompanying resource Web page can assist users in setting up their own servers.     

Colour vision,evolution, and perceptual content

Computational models of colour vision assume that the biological function of colour vision is to detect surface reflectance. Some philosophers invoke these models as a basis for externalism about perceptual content (content is distal) and objectivism about colour (colour is surface reflectance). In an earlier article (Thompson et al. 1992), I criticised the computational objectivist position on the basis of comparative colour vision: There are fundamental differences among the colour vision of animals and these differences do not converge on the detection of any single type of environmental property. David R. Hilbert (1992) has recently defended computational objectivism against my comparative argument; his arguments are based on the externalist approach to perceptual content originally developed by Mohan Matthen (1988) and on the computationally inspired theory of the evolutionary basis for trichromacy developed by Roger N. Shepard (1990). The present article provides a reply to Hilbert with extensive criticism of both Matthen's and Shepard's theories. I argue that the biological function of colour vision is not to detect surface reflectance, but to provide a set of perceptual categories that can apply to objects in a stable way in a variety of conditions. Comparative research indicates that both the perceptual categories and the distal stimuli will differ according to the animal and its visual ecology, therefore externalism and objectivism must be rejected.Versions of this article were read to the Department of Philosophy at the University of Chicago and to the Department of Philosophy at Boston University. I am grateful to the audiences for the discussions that ensued. I am also grateful to an anonymous referee for constructive criticism of certain points in the article. Special thanks are due to my comparative colour vision collaborators, Adrian Palacios and Francisco Varela.     

Romantic partners and body image disturbance: Further evidence for the role of perceived—actual disparities

In this study, female and male college dyads (primarily Caucasian) involved in a “romantic relationship” used schematic figures to rate their conceptions of body size on a variety of rating protocols, including actual self, ideal self, ideal opposite gender, perceived partner's ideal opposite gender, perceived partner's rating of self, and rating of partner's body size. Based on the reflected-appraisal literature and previous body image research on perceived—actual disparities in body size ratings, five discrepancy indices were created and related to dispositional levels of body image disturbance, eating dysfunction, and general psychological function (self-esteem, depression). The results clearly indicated gender differences in the particular predictor associated with all measures of disturbance. For females, the discrepancy between the Self rating and the Perceived Partner's Ideal Other Gender rating accounted for almost all of the variance associated with clinical indices of disturbance. For males, the discrepancy between the Self rating and the Actual Partner's Ideal Other Gender rating was the only important predictor to emerge in regression analyses. The findings are interpreted in light of recent research on actual/perceived differences in body size ratings.     

Stereotyped movement disorder in an adult following acquired brain injury: Effect of environmental stimulation

In the present study, a naturalistic functional analysis procedure was used to assess the effect of environmental stimulation on the stereotypic behavior (body rocking) of an adult whose stereotypy appeared to be induced by an acquired brain injury. Environmental stimulation, operationalized in terms of both physical and social characteristics, resulted in only minimal changes in the occurrence of body rocking. Body rocking occurred in excess of 50% of the observations in all environmental stimulation conditions and in a naturally occurring baseline condition. To our knowledge, this is the first published report of a functional analysis of stereotypy associated with acquired brain injury.     

Grammatical determinants of ambiguous pronoun resolution

Crawley et al. (1990) argue for the primacy of a subject assignment strategy for pronoun assignment during reading, and against the notion of parallel function (Sheldon, 1974). However, most of their items deviated from parallel structure, and none included subject pronouns. In four experiments with subject and nonsubject pronouns, strong parallel function effects emerge when a potential antecedent has the same syntactic role as the pronoun and when the two clauses have the same attachment site and constituent structure. Attachment nonparallelism causes the greatest ambiguity, while the other types lead to more subject assignment overall, although there is always an overlaid parallel function effect. These observations support a model of pronoun assignment according to which potential antecedents are checked for morphological, syntactic and semantic feature matches with the pronoun, and priming/reactivation of syntactic structure across clauses facilitates parallel assignment.This research was supported in part by research grant 410-89-0395 from the Social Sciences and Humanities Research Council of Canada. A preliminary version of the paper was presented at the 1992 meetings of the Canadian Linguistic Association in Charlottetown, Prince Edward Island. I would like to thank Elizabeth Cowper, Keren Rice, Rosemary Stevenson, and an anonymous reviewer for their comments.     

The effects of maternal employment and non-maternal infant care on development at two and four years

Differences in maternal employment during children's first year of life and children's entry into non-maternal care before the age of 1 year failed to predict differences in cognitive and socioemotional development at 2 and 4 years of age, after family background variables were controlled. Two samples were studied: a population sample of 1100 Bermudian children and a smaller subsample of children most of whom were determined to be at risk for developmental problems. To assess the effects of maternal employment, we compared infants with mothers who worked 20 or more hours a week to infants with mothers who worked less than 20 hours a week. To assess the effects of entry into non-maternal care before the age of one, we compared infants who were placed in regular non-maternal care before the age of one versus infants who did not experience regular non-maternal care before the age of one. The results revealed that family background variables frequently predicted many child outcome measures in both the total sample and the smaller research sample. After controlling for family characteristics, no differences were found between children whose mothers worked 20 or more hours a week when they were infants and children with mothers who worked less than 20 hours a week in either sample. In addition, age of entry into non. maternal care before the age of one did not significantly predict any child outcome measures.
