Beyond the Grand Illusion: What Change Blindness Really Teaches Us About Vision

Experiments on scene perception and change blindness suggest that the visual system does not construct detailed internal models of a scene. These experiments therefore call into doubt the traditional view that vision is a process in which detailed representations of the environment must be constructed. The non-existence of such detailed representations, however, does not entail that we do not perceive the detailed environment. The “grand illusion hypothesis” that our visual world is an illusion rests on (1) a problematic “reconstructionist” conception of vision, and (2) a misconception about the character of perceptual experience.     

Going the distance: Extra-symbolic contributions to the symbolic control of spatial attention

Over the past 30 years, researchers have used symbolic cues such as spatial words and arrows to direct observers' attention to the location of target objects that appear at a single, fixed distance in simple visual environments; however, they have done so by using symbolic cues that provide only partial—directional—information about the spatial location of target objects. Thus, it remains unclear whether observers can only shift their attention broadly in the cued direction in response to these cues or whether they can shift their attention to the specific location of the target by combining an expectation about direction (derived from apprehension of the directional cue) with an expectation about distance (derived from some extra-symbolic cue). The results of two experiments showed that observers do shift their attention to relatively coarse spatial locations by combining expectancies about direction and distance, and that the extent to which observers do so is modulated by the presence of visible markers and the expected distance of the target. These findings are important because they provide the first evidence that extra-symbolic information about distance contributes to the symbolic control of spatial attention.     

The ecological imagination

This paper offers a psychoanalytic exploration of meaning within the concept of ecology. From a starting point in the experience of primal anxiety, originating in the work of Freud, Jung and Klein, links are made to cultural themes through a developing comparison of case studies in literature, mythology, the public sphere and clinical practice. It is argued that the application of psychoanalytic ideas to environmental concern has validity. The idea emerges that individual and public attitudes to our environment might be open to positive change through an appreciation of the concept of early anxiety, currently available to us in work of the imagination.     

Effects of exposure to thin-ideal media images on body dissatisfaction: Testing the inclusion of a disclaimer versus warning label

The current study was designed to determine whether the inclusion of a disclaimer (i.e., “Retouched photograph aimed at changing a person's physical appearance.”) or warning (i.e., “Warning: Trying to look as thin as this model may be dangerous to your health.”) added to images of thin/attractive models would affect body dissatisfaction and intent to diet in female undergraduate students (n = 342). Participants were randomly assigned to one of four groups: (a) disclaimer, (b) warning, (c) model control, or (d) car control. Results revealed a significant interaction between group and time, whereby only the car control group reported a significant change (i.e., decrease) in body dissatisfaction over time. Groups did not differ on intent to diet measured at post-exposure. The results largely replicate other findings in this area and call into question advocacy efforts to label media images as a strategy to decrease women's identification with the stimuli.     

Factors Associated with Perceived Paternal Involvement in Childrearing

Interest in paternal involvement in child care has increased as the demands on the time and resources of maternal caretakers have increased. The purpose of the present study was to examine variables associated with perceived paternal involvement in child care. Participants were 137 (90 European American and 47 African American) fathers of children between the ages of 2 and 6. Hierarchical multiple regression and analyses of variance indicated that ethnicity, gender role orientation, and perceived skill at child care were associated with higher levels of perceived paternal engagement in and responsibility for child care. Partners' work status was associated with perceived paternal responsibility for, but not engagement in child care. Data suggest that fathers' perceptions of their abilities, gender role, and family requirements may combine to influence child care involvement.     

“Statistical,” “Practical,” and “Clinical”: How Many Kinds of Significance Do Counselors Need to Consider?

The present article reviews and distinguishes 3 related but different types of significance: “statistical,” “practical,” and “clinical.” A framework for conceptualizing the many “practical” effect size indices is described. Several effect size indices that counseling researchers can use, or that counselors reading the literature may encounter, are summarized. A way of estimating “corrected” intervention effects is proposed. It is suggested that readers should expect authors to report indices of “practical” or “clinical” significance, or both, within their research reports; and it is noted that indeed some journals now require such reports.     

Sources of variability in sequelae of very low birth weight.

Few investigations have examined the specificity of sequelae of very low birth weight (VLBW, <1500 g) or sources of variability in outcome. To better understand the nature and determinants of outcome, we assessed neuropsychological and achievement skills at mean age 11 years in 62 children with <750 g birth weight, 54 with 750-1499 g birth weight, and 66 term-born controls. Distinct cognitive constructs were identified by factor analysis, and the three birthweight groups were compared on these constructs and on composite measures of achievement. Although the group with <750 g birth weight performed less well on all tests than term-born controls, group differences in a perceptual planning factor and in mathematics remained even when IQ was controlled, and deficits were more pronounced in mathematics than in reading. Results from structural equation modeling were consistent with the hypothesis that neuropsychological skills mediated the relationship between birth weight and achievement. The findings confirm the differential deficit hypothesis, support the need to consider multiple sources of variability in VLBW outcomes, and highlight the importance of neuropsychological constructs in developing an explanatory framework.     

Distinguishing the cognitive and behavioral consequences of attitude importance and certainty: A new approach to testing the common-factor hypothesis

Some published factor analyses have suggested that attitude importance and certainty are distinct psychological constructs, but other factor analytic investigations have suggested they are largely redundant reflections of a more general underlying construct. This latter sort of finding has led investigators to average measures of importance and certainty together into a composite index and then explore its cognitive and behavioral consequences. In this paper, we report three studies gauging the underlying structure of these strength-related attitude attributes by assessing whether they in fact relate in the same ways to information processing and action tendencies. We found that importance and certainty both independently predicted the likelihood that a person attempted to persuade others to adopt his or her attitude. Importance (but not certainty) was associated with the tendency to seek out information that would enable people to use their attitudes in a subsequent judgment and only importance predicted whether or not they turned out to vote in an election to express their attitudes. Certainty (but not importance) was related to the tendency to find more than one political candidate acceptable. And importance and certainty interacted to predict the frequency with which people performed attitude-expressive behaviors. All this suggests that importance and certainty have distinct effects on thinking and behavior and supports the maintenance of conceptual and empirical distinctions between them in social psychological theory building.
