Sensitivity to attachment, alignment, and contrast polarity variation in local perceptual grouping

A number of leading theories (e.g., Grossberg & Mingolla, 1985; Kellman & Shipley, 1991; Rensink & Enns, 1995) commonly assume that perceptual grouping by contour alignment occurs preattentively across reversing contrast polarity elements. We examined this notion in seven visual search experiments. We found that only grouping by attachment supported preattentive visual search and that grouping by contour alignment required attention in order to operate. Both attachment grouping and grouping by contour alignment were sensitive to contrast reversals. Further results showed that contour alignment was a strong grouping cue only among elements with the same contrast sign but that it did not facilitate grouping across reversing contrast. These results suggest that grouping by contour alignment operates only on inputs of consistent contrast polarity.     

Fitting in with the flock: Social attractiveness as a mechanism for well‐being in religious groups

For most people, religion is practiced and experienced within a social group of believers who interact regularly. Yet the role of social psychological intergroup processes has largely been ignored with respect to religious phenomena. The present study explores social attraction as a mechanism by which religious groups affect the psychological well‐being of their members. Data were taken from a large survey of the members of 411 religious congregations in the United States. Linear mixed modeling analyses were conducted predicting two aspects of well‐being in the religious context from a range of variables at the levels of the individual, of the group, and of individual–group fit. Fit measures between individual characteristics and norms within congregations were found to be significant predictors of well‐being for a variety of measures across domains of demographics, religious beliefs, religious behavior, and group integration. These results support the view that the intragroup process of social attraction is a mechanism by which people obtain some benefits from belonging to religious groups.

Practical Reason,Sympathy and Reactive Attitudes

This paper has three aims. First, I defend, in its most radical form, Hume's scepticism about practical reason, as it applies to purely self‐regarding matters. It's not always irrational to discount the future, to be inconstant in one's preferences, to have incompatible desires, to not pursue the means to one's ends, or to fail to maximize one's own good. Second, I explain how our response to the “irrational” agent should be understood as an expression of frustrated sympathy, in Adam Smith's sense of sympathy, rather than a genuine judgement about Reason. We judge these people because we cannot imaginatively identify with their desires and attitudes, and this is frustrating. Third, compared to the standard cognitive view, my account better explains the nature of our criticism of the “irrational,” and, by portraying “irrationality” as a cause of upset to other people, provides a better normative basis for being “rational.”     

Positive and negative intergroup contact predict Black and White Americans' judgments about police violence against Black Americans

We examined whether past positive and negative interracial contact predict people's views of interracial police violence. White (N = 207) and Black (N = 116) Americans reported on their past intergroup experiences before viewing information about one of two true events involving the death of a Black man at the hands of a White police officer. For White Americans, negative contact predicted a reluctance to blame the officer and a willingness to believe that people's responses to the events involved “playing the race card.” For Black Americans, positive contact predicted marginally less officer blame and lower beliefs that the victim was racially profiled. This suggests the potential for a vicious cycle, whereby past contact experiences color perceptions of intergroup conflict in the present.     

Recollections of Childhood Religious Identity and Behavior as a Function of Adult Religiousness

People have a strong motivation to maintain a self-concept that is coherent and consistent over time. Religion is a central source of social identity for many people, but its importance is prone to dramatic change across the life course. To maintain a consistent perception of self, recollections of one's own past religiousness may shift to better fit with the present. This study examined changes between early and middle adulthood in retrospective perceptions of religious behavior and identity in childhood. Data from a population-based birth cohort sample were matched with data from individuals who participated in at least 2 of 3 adult follow-up studies, at intervals of approximately 10 years. Logistic regression was used to analyze the association of final recollections of childhood behavior and identity with previous recollections and current religious characteristics. Consistent with the predictions of temporal self-appraisal theory, participants' perception of their religious identity as children tended to change over time to match their adult religious identity. Recollections of childhood religious behavior were more stable than recollections of religious identity, and change was unrelated to adult behavior. These results have implications for studying religious characteristics using retrospective measures, regarding their accuracy and their independence from contemporary measures.     

Race-contingent aftereffects suggest distinct perceptual norms for different race faces

Faces of one's own race and of other races are thought to be located in different regions of face space (Valentine, 1991 Valentine, T. 1991. A unified account of the effects of distinctiveness, inversion, and race in face recognition. Quarterly Journal of Experimental Psychology, 43A: 161–204. [Taylor & Francis Online] , [Google Scholar]). Here we investigated whether faces of different races (Caucasian and Chinese faces) have dissociable neural coding and distinct norms. We used adaptation techniques to alter perceptions of normality (aftereffects) for faces. Caucasian and Chinese participants adapted to distorted faces of one race (e.g., Chinese contracted faces—Experiment 1), or oppositely distorted faces of both races (e.g., Chinese contracted and Caucasian expanded faces—Experiment 2). We then tested for aftereffects in Chinese and Caucasian test faces. In Experiment 1 aftereffects were reduced when a change in race between the adapt faces and test faces occurred. In Experiment 2 aftereffects occurred in opposite directions for the two races. These results demonstrate that dissociable neural populations code faces of different races and suggest the existence of race-specific face norms.     

Older Mexican Americans and God-mediated control: exploring the influence of Pentecostal/Evangelical affiliation

A growing number of Mexican Americans are leaving the Catholic Church to join Pentecostal and Evangelical congregations. The purpose of this study is to explore the benefits that are associated with joining Pentecostal and Evangelical congregations. A latent variable model is specified that contains the following core relationships: (1) older Mexican Americans who affiliate with Pentecostal/Evangelical congregations will attend worship services more often; (2) older Mexican Americans who attend church more often will receive more spiritual support from their fellow church members; (3) older Mexican Americans who receive more spiritual support will develop a closer relationship with God; and (4) older Mexican Americans who have a close relationship with God will develop a stronger sense of God-mediated control. Findings from a nationwide survey of older Mexican Americans provide support for each of these linkages.     

Perceptual and decisional factors influencing the discrimination of inversion in the Thatcher illusion

The Thatcher illusion (Thompson, 1980) is considered to be a prototypical illustration of the notion that face perception is dependent on configural processes and representations. We explored this idea by examining the relative contributions of perceptual and decisional processes to the ability of observers to identify the orientation of two classes of forms-faces and churches-and a set of their component features. Observers were presented with upright and inverted images of faces and churches in which the components (eyes, mouth, windows, doors) were presented either upright or inverted. Observers first rated the subjective grotesqueness of all of the images and then performed a complete identification task in which they had to identify the orientation of the overall form and the orientation of each of the interior features. Grotesqueness ratings for both classes of image showed the standard modulation of rated grotesqueness as a function of orientation. The complete identification results revealed violations of both perceptual and decisional separability but failed to reveal any violations of within-stimulus (perceptual) independence. In addition, exploration of a simple bivariate Gaussian signal detection model of the relationship between identification performance and judged grotesqueness suggests that within-stimulus violations of perceptual independence on their own are insufficient for producing the illusion. This lack of evidence for within-stimulus configurality suggests the need for a critical reevaluation of the role of configural processing in the Thatcher illusion.

THE DISCRIMINATION OF OBJECT NAMES AND OBJECT SOUNDS IN CHILDREN WITH AUTISM: A PROCEDURE FOR TEACHING VERBAL COMPREHENSION

We assessed whether 2 preschoolers with autism learned to discriminate between the sounds of musical instruments more rapidly than the spoken names of the instruments. After the children learned the sound‐object relations more rapidly than the name‐object relations, we then evaluated a prompt‐delay procedure for transferring stimulus control from the sounds to the names of the instruments. The prompt‐delay procedure facilitated the acquisition of name—object relations for both children.
