A simple system for monitoring the timing of infant gaze to stimuli at specific locations

A system for monitoring the timing of infant gazes to specific locations is described. Infants sit on a parent’s lap in a dark room and observe videotaped stimuli presented on one of four monitors. Infrared (IR) light sources provide illumination for an IR-sensitive video camera and are positioned so that the infant’s direction of gaze can be readily apprehended on the basis of the reflections of the IR light sources relative to the infant’s pupil. The parent monitors the infant’s eyes through a headmounted display and keeps the infant in view of the video camera. Direction and timing of gaze shifts can be coded from frame-by-frame inspection of the videotape. We demonstrate that this coding is relatively accurate and that the present system provides some advantages over coding gaze direction on the basis of an unembellished video recording.     

Word shape's in poor shape for the race to the lexicon

Current models of fluent reading often assume that fast and automatic word recognition involves the use of a supraletter feature corresponding to the envelope or shape of the word when it is printed in lowercase. The advantages of mixed case over pure case and of pure lowercase over pure uppercase have often been taken as evidence favoring the word-shape hypothesis. Alternative explanations for these phenomena are offered. Experiment 1 shows that previous demonstrations of word-shape effects during proofreading are better described as individual letter effects. Experiments 2-4 explore the possibility that word shape facilitates lexical access through uncertainty reduction. In all three experiments performance on words with rare shapes is compared to those with common shapes. There were no effects of shape frequency in either tachistoscopic recognition or lexical-decision tasks. This was true regardless of the degree to which the visual shape cue was supplemented by the nonvisual factors of familiarity and expectancy. Possible reasons why fluent readers ignore word shape are discussed within the framework of a model that assumes that automatic word recognition is mediated by the activation of abstract letter identities.     

Successful Rebellious Professionals: The Black Woman's Professional Identity and Community Commitment

Using interview data from a larger career study of 25 black women who have achieved public recognition as workers for change in the black community, this paper explores the experiences of seven black professional women. The conflicts they confronted as black professionals, resolution of those conflicts, the special conditions of conflict resolution through rebellious professionalism, are explored, as well as the curious routes to success which place them in the position of role models to other human services professionals who are organizationally constrained from rebelling in such ways. The implications of these routes to professional success are explored in an effort to understand contemporary nationalism among black professionals and semi-professionals within the context of conflicts between dominant group organizational expectations and black community membership. The data suggest that particularistic commitments do not necessarily conflict with professional ideals if success is defined in terms of community achievements and positive evaluation by colleagues, rather than material rewards.     

Schema shifting: Children's cognitive monitoring of the prose-schema interaction in comprehension

Facility in shifting between familiar schemata in a listening comprehension task was examined in children from the third and sixth grades (8 and 11 years old, respectively). The children heard two consecutively presented ambiguous passages about very familiar daily activities. Comprehension of both passages demanded precisely timed activation of a schema appropriate to each passage. Half of the children were not explicitly cued to the passage shift, thus requiring that they spontaneously recognize the need for a schema shift. Analyses of free recall and interview responses showed that although the younger children had more difficulty than the older children, children at both grade levels demonstrated deficiencies in their cognitive monitoring of the prose-schema interaction.     

Feminist and sympathetic feminist consciousness

Data from the 1976 American National Election Study were used to assess the effects of one outgroup characteristic, belief similarity—dissimilarity, on the enhancement of women's feminist consciousness. Women were focused on as the ingroup and men as the outgroup. The sample consisted of 677 women who believed that women should have an equal role with men. Outgroup belief similarity referred to women's perception that most men supported an equal role for women and outgroup dissimilarity to the perception that men did not support an equal role. Results indicated that outgroup belief similarity significantly enhanced women's feminist consciousness. Women who supported an equal role and perceived outgroup belief dissimilarity scored higher on cognitive and behavioural measures of feminist consciousness than those who supported an equal role but did not perceive outgroup dissimilarity. Secondary analyses were undertaken assessing the effect of ingroup belief similarity dissimilarity on the enhancement of sympathetic feminist consciousness among men.     

Perceptual sampling of orthogonal straight line features

Summary Among mathematical models of visual confusion of letters and similar material, those that posit a feature detection process have been especially popular. The present study provides direct tests of several of the central assumptions of such models with feature-stimuli composed of the blank, one of two straight line features, or both line features positioned at a right angle. In one condition, the two features were connected when they appeared together, whereas in the other condition they were separated by a gap. A model which makes the strong assumptions that the features are sampled (detected) independently and then reported in a direct, unbiased fashion, performed acceptably in both conditions. Feature dependency models and those positing a biased decision process were ruled out on the basis of poor fits or lack of parsimony. The perceptibility (d) of a specific feature depended on the stimulus that contained it in the Gap condition but not in the Connected condition. The relative perceptibility of the horizontal vs in the vertical features was also different in the Gap vs Connected conditions. The results were compared with other recent studies, including ones in which sampling independence was falsified, apparently because of greater stimulus complexity, and employing a stimulus set that did not contain all possible combinations of features.We would like to thank J.T.
