Download or read book The Spiral Aftereffect Influence of Stimulus Size and Viewing Distance on the Duration of Illusory Motion written by William E. Collins and published by . This book was released on 1968 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study examined some effects of stimulus size and distance on the persistence of one type of illusory motion, viz., the spiral aftereffect (SAE). Duration of SAE was investigated with stimuli of 2, 4, 8, 12, and 16 inches in diameter. The distance between the observers and the rotating spirals was varied to produce visual angles between 1 deg. 12 min. and 18 deg. 56 min. of arc. Data indicate that the duration of illusory motion reaches peak values between approximately 2 deg.-4 deg. of visual angle. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Decision Processes in Visual Perception explores the relationships between the organization of a complex visual pattern by the perception system and the molecular activity involved in the discrimination of differences in magnitude or intensity between two stimulus elements. The text discusses the basic principles of discrimination, identification, and self-regulation of the perception system; demonstrates how adaptive decision modules emerge from multiple constraints; shows how combinations of simple decisions lead to complex judgmental tasks; and synthesizes traditional approaches to perception in order to clarify the crucial and pervasive role of these modules in the overall activity of perceptual organization. Psychologists, neuroscientists, molecular biologists, and physiologists will find the book invaluable.

This book was released on 1971 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many safety problems encountered in aviation have been attributed to visual illusions. One of the various types of visual illusions, that of apparent motion, includes as an aftereffect the apparent reversed motion of an object after it ceases real movement. The study examined some effects of perceived size, perceived distance, and perceived stimulus speed on the persistence of illusory motion in the spiral aftereffect. Two major conditions were used: Size Constant: a 4-inch spiral was positioned to subtend visual angles of 1/2, 1, 2, 4, and 8 deg with seven rates of retinal speed (10-100 minarcs/sec) used at each angle; Angle Constant: three sizes of spirals were positioned so that each subtended visual angles of 2, 4, and 8 deg with physical speed held constant (75 rpm) in one case, and retinal speed (45 minarcs/sec) held constant in another. Durations of the illusion were significantly affected by low retinal speeds, by small visual angles, and by perceived size per unit of retinal size. The results suggest that complex interactions of physical and perceptual factors can significantly alter the presence and the magnitudes of visual illusions of motion. (Author).

This book was released on 1965 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the stationary spiral itself as a test object 8 ft. from S, the duration of the spiral aftereffect was measured in three experiments which varied diameter, direction and speed of rotation of spiral, inspection time, number of turns and relative proportion of black and white. Duration of the aftereffect increased as number of turns of the spiral increased from 1.5 to 3.5, as inspection time increased from 15 - 120 sec. and as the relative width of light and dark bands decreased from 1:5 to 5:1. The aftereffect was longer with the expanding condition than with the contracting one. It decreased as spiral diameter changed from 4 or 8 to 16 in. corresponding to changes in visual angle ranging from 2 degrees to 9 degrees. Speeds of 25, 100 and 250 RPM did not produce significant differences although an interaction was found between speed and number of turns. (Author).

Download or read book The Spiral Aftereffect Ii Influences of Visual Angle and Retinal Speed on the Duration and Intensity of Illusory Motion written by Mary Jane Williams and published by . This book was released on 1969 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual illusions have been a persistent problem in aviation research. The spiral aftereffect (SAE) is an example of one type of visual illusion--that which occurs following the cessation of real motion. Duration and intensity of the SAE was evaluated under five conditions. Results indicate that perceived (rather than physical) characteristics of the stimulus situation may have the most significant effects on duration of the SAE. The findings thus have considerable pertinence to the evaluation of effective factors in the production of a variety of other visual illusions which can occur in aviation environments. (Author).
Download or read book Current Topics in Clinical and Community Psychology written by Charles D. Spielberger and published by Academic Press. This book was released on 2013-10-22 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Topics in Clinical and Community Psychology, Volume 1 reviews advances in clinical and community psychology. Topics covered include theory and research in areas such as psychological assessment of intelligence, personality, and abnormal behavior; psychotherapy, broadly defined to include counseling and behavior modification; and psychophysiological and neurological determinants of personality and psychopathology. Comprised of five chapters, this volume first illustrates how reinforcement and modeling techniques can enable psychologists to function effectively as mental health consultants and agents of social change in an institution for delinquent children. The second chapter describes a unique program designed to prevent emotional dysfunction in school children by combining effective therapeutic intervention with relevant research and evaluation. The third chapter challenges the relevance of psychological research that does not take into account the relationship between the experimenter and his subjects, and instead demonstrates the impact of experimenter self-disclosure on the responses given to psychological tests and on subjects' behavior in psychology experiments. The fourth chapter proposes a behaviorally oriented model for the assessment of positive mental health and describes a successful application of this model in the assessment of the competence of college freshmen. The final chapter relates research on human psychophysiology to problems of psychological assessment and psychotherapy that are of central concern to clinical psychologists. This book should prove useful to practicing clinical and community psychologists, graduate and undergraduate students of psychology, and members of other mental health professions.
