A DEVELOPMENTAL DEFICIT IN LOCALIZING OBJECTS FROM VISION

Abstract— We describe a college student, A. H., with a developmental deficit in determining the location of objects from vision. The deficit is selective in that (a) localization from auditory or tactile information is intact, (b) A H reports the identity of mislocalized objects accurately, (c) visual localization errors preserve certain parameters of the target location, and (d) visual localization is severely impaired under certain stimulus conditions, but nearly intact under other conditions. These results bear on the representation and processing of location information in the visual system, and also have implications for understanding developmental dyslexia.     

REFLECTIONS ON AFFIRMATIVE ACTION GOALS IN PSYCHOLOGY ADMISSIONS

Four goals of affirmative action in higher education are described as they relate to psychology admissions. Broadly conceived, these goals are compensating for past injustice, correcting present inequity, promoting intellectual diversity, and enhancing the presence of role models. It is argued that the four goats differ in their underlying assumptions about the purposes of affirmative action and that these differences can result in disparate admission decisions. Data from three experiments on decision making in graduate psychology admissions are presented to illustrate the analysis. In these studies, academic psychologists rated the admissibility of hypothetical graduate student applicants who varied on a number of characteristics (e g., ethnicity, social class, interest in minority research) pertinent to affirmative action. A consistent pattern of ethnic group differences in admissibility ratings was documented, illustrating that compensation for past injustice can be interpreted as a salient affirmative action goal in graduate admissions decisions. Implications of the analysis for clarifying admissions decisions guided by affirmative action goals are discussed.     

Judging others in the shadow of suspicion

Previous research has found that when perceivers have reason to be suspicious of the motives underlying an actor's behavior, they are likely to draw inferences about the actor's true disposition that reflect a relatively sophisticated style of attributional processing. The present research was designed to examine some of the negative consequences that suspicion can have on perceivers' judgments. In each of the three studies reported, some subjects were made suspicious about the motives of an actor on the basis of contextual information surrounding the actor's behavior, rather than the behavior itself. Results of these studies suggest that, particularly when perceivers believe that the actions or motives of the actor could affect them, suspicion may cause perceivers to see the actor in a more negative light, even if the perceivers are not convinced that the actor's behavior was indeed affected by ulterior motives.The authors thank Patrick Carver and Gilbert Fein for their assistance with the stimulus materials for Study 1, and Jessica Cross, Thomas Tomlinson, and Amy Elmore for their assistance with Studies 2 and 3.     

Propositional attitudes and formal ontology

This paper develops — within an axiomatic theory of properties, relations, and propositions which accords them well-defined existence and identity conditions — a sententialist-functionalist account of belief as a symbolically mediated relation to a special kind of propositional entity, theproxy-encoding abstract proposition. It is then shown how, in terms of this account, the truth conditions of English belief reports may be captured in a formally precise and empirically adequate way that accords genuinely semantic status to familiar opacity data.I am deeply indebted to Edward Zalta for many helpful comments and suggestions.     

Factor analytic structure of theScale to Asses World View

This article reports on the factor structure of theScale to Assess World View ^(c) (SAWV). Alpha reliabilities for the factors are presented. Gender differences in world views are also explored to understand how men and women in this sample viewed the world. Recommendations for client assessment, therapy, education and training, and scale revision are discussed. The research reported here is based on a paper presented at the annual meeting of the American Psychological Association, Washington, DC, August 17, 1992.     

Attentional misguidance in visual search

Previous research has shown that a task-irrelevant sudden onset of an object will capture an observer’s visual attention or draw it to that object (e.g., Yantis & Jonides, 1984). However, further research has demonstrated the apparent inability of an object with a task-irrelevant but unique color or luminance to capture attention (Jonides & Yantis, 1988). In the experiments reported here, we reexplore the question of whether task-irrelevant properties other than sudden onset may capture attention. Our results suggest that uniquely colored or luminous objects, as well as salient though irrelevant boundaries, do not appear to capture attention. However, these irrelevant features do appear to serve as landmarks for a top-down search strategy which becomes increasingly likely with larger display set sizes. These findings are described in terms of stimulus-driven and goal-directed aspects of attentional control.     

Latent Structure of the Sources of Mathematics Self-Efficacy

General social cognitive theory and its career-specific elaborations posit four primary sources through which self-efficacy beliefs are acquired and modified: personal performance accomplishments, vicarious learning, social persuasion, and physiological states and reactions. We present two studies exploring the dimensionality of these sources within the context of career-relevant mathematics activities. In Study 1, 295 college students completed measures of the source variables. Testing two- through five-factor models, we found strongest support for a four-factor latent structure of the efficacy sources. In Study 2, involving 481 high school students, a five-factor model fit the data well. We also found evidence of a higher order factor structure in both samples. Several directions for further research on the sources of efficacy information are considered, along with implications for career and academic interventions.     

Parental Smoking and the “Epidemic” Spread of Cigarette Smoking1

“Epidemic” models of transitions between stages of cigarette smoking describe the spread of smoking behavior through face-to-face encounters. An epidemic model was successfully fitted that allowed epidemic parameters to be conditioned on the smoking status of adolescents' parents. Model comparisons supported the conclusion that the transition from nonsmoker to trier involved social contacts, whereas the transition from trier to regular smoker was best modeled as a constant rate (i.e., did not depend on the population prevalence of smokers). The transition rate from nonsmoker to trier was more rapid in children of smoking parents than in children of nonsmoking parents. Adolescents with and without smoking parents did not differ in the rate of transition from trier to regular smoking.
