A large part of the empirical research in the field of visual attention has focused on various concrete paradigms. However, as yet, there has been no clear demonstration of whether or not these paradigms are indeed measuring the same underlying construct. We collected a very large data set (nearly 1.3 million trials) to address this question. We…

The type of visual information needed for categorizing faces and nonface objects was investigated by manipulating spatial frequency scales available in the image during a category verification task addressing basic and subordinate levels. Spatial filtering had opposite effects on faces and airplanes that were modulated by categorization level. The…

Evidence presented by psychologists has indicated that perceptual development results in part from learned experience and may be modified to varying deqrees by social pressure. Since vision is a primary source of perceptual information for art education, this study sought to determine the effects of prophecy, or expectation, on perceptual response…

Butler (1980) compared errors representing intrusions and mislocalizations on 3x3 letter displays under pattern-mask versus no-mask conditions and found that pattern masking increased character mislocalization errors (naming a character in the display but not in the target position as being the target) over intrusion errors (naming a character not…

THIS STUDY WAS CONDUCTED TO INVESTIGATE THE EFFECTS OF VARIATIONS IN THE SPEED AND DIRECTION OF A FLYING OBJECT ON VISUO-PERCEPTUAL JUDGMENTS MADE, DIFFERENCES IN THE ABILITY OF SKILLED AND UNSKILLED SUBJECTS IN MAKING SUCH JUDGMENTS, AND THE EFFECTS OF AGE OR MATURITY LEVEL ON THE SPEED AND ACCURACY OF SUCH JUDGMENTS. THE SUBJECTS WERE 54 MALE…

Yunger children, like adults, are found to demonstrate active tactual horizontal-vertical illusions that are like those obtained in vision. (Authors)

Examined critical features of tactile and kinesthetic processes by administering 8 traditional psychometric instruments and 14 measures of tactile and kinesthetic perceptual processes to 116 female college students in Australia. Results show, as is consistent with earlier findings, that visual-spatial processes are difficult to separate from…

The defining attributes of analytic ability as they relate to theoretical cognitive styles were explored in a study using a sample of 492 males aged 16-21 years. The Group Embedded Figures Test (GEFT--Witkin, Oltman, Rasher, and Karp) was used to measure field dependent and independent aptitude. Scores on the GEFT were compared with scores on an…

The difference in cognitive resources required for imagination and perception was tested in two experiments by examining the reduced substitutability of imagination and perception in problem solving by college undergraduates. Eighty subjects in Experiment 1 drew capital letters from lines or descriptions of lines in a seven-page booklet. The…

A common paradigm in measuring the ability to recognize facial expressions of emotion is to present photographs of facial expressions and to ask subjects to identify the emotion. The Affect Blend Test (ABT) uses this method of assessment and is scored for accuracy on specific affects as well as total accuracy. Another method of measuring affect…

To measure how the complexity of a television image affects the viewer's ability to identify or recognize visual details within the image, two coders rated the form complexity of 30 public service announcements, basing their evaluation on the familiarity of the images in the announcements, the rate at which they presented new information, and the…
