Processing Asymmetries

Two experiments investigated visual processing asymmetries in normal and dyslexic readers, with unilateral tachistoscopic presentations. The experiments employed randomized or blocked presentations of verbal and nonverbal materials to determine whether previously reported differences between dyslexics and normals were due to structural hemispheric differences or to strategical processing differences. The results indicate that if dyslexics are unable to predict the nature of the stimulus, then they behave as normal readers. Their atypical laterality emerges only when they can adopt a strategy in anticipation of a specific type of stimulus. This leads to the suggestion that developmental dyslexia is associated more with inappropriate modes of thought than it is with hemispheric dysfunction.

Processing Mechanisms

The role of top-down processing on the horizontal-vertical line length illusion was examined by means of an ambiguous room with dual visual verticals. In one of the test conditions, the subjects were cued to one of the two verticals and were instructed to cognitively reassign the apparent vertical to the cued orientation. When they have mentally adjusted their perception, two lines in a plus sign configuration appeared and the subjects had to evaluate which line was longer. The results showed that the line length appeared longer when it was aligned with the direction of the vertical currently perceived by the subject. This study provides a demonstration that top-down processing influences lower level visual processing mechanisms. In another test condition, the subjects had all perceptual cues available and the influence was even stronger.

Abstract. This project compared the relative performance of professional dancers and nondancers on the Music Apperception Test (MAT; van den Daele, 2014 ), then compared dancers’ performance on the MAT with that on the Thematic Apperception Test (TAT; Murray, 1943 ). The MAT asks respondents to “tell a story to the music” in compositions written to represent basic emotions. Dancers had significantly shorter response latency and were more fluent in storytelling than a comparison group matched for gender and age. Criterion-based evaluation of dancers’ narratives found narrative emotion consistent with music written to portray the emotion, with the majority integrating movement, sensation, and imagery. Approximately half the dancers were significantly more fluent on the MAT than the TAT, while the other half were significantly more fluent on the TAT than the MAT. Dancers who were more fluent on the MAT had a higher proportion of narratives that integrated movement and imagery compared with those more fluent on the TAT. The results were interpreted as consistent with differences observed in neurological studies of auditory and visual processing, educational studies of modality preference, and the cognitive style literature. The MAT provides an assessment tool to complement visually based performance tests in personality appraisal.

The Feminine

Past research has shown that the gender typicality of applicants’ faces affects leadership selection irrespective of a candidate’s gender: A masculine facial appearance is congruent with masculine-typed leadership roles, thus masculine-looking applicants are hired more certainly than feminine-looking ones. In the present study, we extended this line of research by investigating hiring decisions for both masculine- and feminine-typed professional roles. Furthermore, we used eye tracking to examine the visual exploration of applicants’ portraits. Our results indicate that masculine-looking applicants were favored for the masculine-typed role (leader) and feminine-looking applicants for the feminine-typed role (team member). Eye movement patterns showed that information about gender category and facial appearance was integrated during first fixations of the portraits. Hiring decisions, however, were not based on this initial analysis, but occurred at a second stage, when the portrait was viewed in the context of considering the applicant for a specific job.
