A rapid serial visual presentation (RSVP) technique was used to investigate the role of the nature of processing carried out on targets in the Lag-1 sparing phenomenon. Lag-1 sparing refers to a higher accuracy in the task associated with the 2nd target when the 2 targets are immediately successive in the RSVP stream relative to when there are 1…

The authors investigated the calibration of reach distance by gradually distorting the haptic feedback obtained when participants grasped visible target objects. The authors found that the modified relationship between visually specified distance and reach distance could be captured by a straight-line mapping function. Thus, the relation could be…

Previous research, in which static figures were used, showed that the ability to perceive illusory contours emerges around 7 months of age. However, recently, evidence has suggested that 2-3-month-old infants are able to perceive illusory contours when motion information is available (Johnson & Mason, 2002; Otsuka & Yamaguchi, 2003). The present…

The consistent, but often wrong, impressions people form of the size of unseen speakers are not random but rather point to a consistent misattribution bias, one that the advertising, broadcasting, and entertainment industries also routinely exploit. The authors report 3 experiments examining the perceptual basis of this bias. The results indicate…

A label can efficiently convey nonobvious information about category membership, but this information can sometimes conflict with one's own expectations. Two studies explored whether 24-month-olds (N = 56) would be willing to accept a category label indicating that an animal (Study 1) or artifact (Study 2) that looked like a member of one familiar…

Active externalism (also known as the extended mind hypothesis) says that we use objects and situations in the world as external memory stores that we consult as needs dictate. This gives us economies of storage: We do not need to remember that Bill has blue eyes and wavy hair if we can acquire this information by looking at Bill. I argue for a…

Use of the Slingerland Screening Tests to detect auditory, visual, and kinesthetic handicaps among children in the classroom is advocated in reference to implementation of Tennessee Public Law 839 which mandates educational services for handicapped persons 4 to 20 years of age. (JC)

Lowenfeld (1945) developed a series of six instruments which could be used to identify perceptual abilities. For this study, the visually oriented person was defined as the objective viewer of the environment, while the haptic person was defined as a person who uses the eyes only when forced to do so and relates to his environment subjectively. He…

PERCEPTION IS DEFINED AS THE MEANINGFUL RESPONSE TO THE VISUAL OR ORAL SIGNAL WHICH IS UNIVERSALLY REFERRED TO AS WORDS. PERCEPTION INCLUDES THE AROUSAL OF MEANING AND IS A CONSCIOUSNESS OR AN AWARENESS OF THE EXPERIENCES ELICITED BY THESE VISUAL OR ORAL SIGNALS. IMPROVING WORD PERCEPTION INVOLVES AT LEAST THE FOLLOWING THREE PROCESSES WHICH ARE…

A STUDY WAS CONDUCTED TO DETERMINE WHETHER AUDIOVISUAL PERCEPTUAL ABILITY CAN ACCOUNT FOR READING ACHIEVEMENT. SUBJECTS WERE 120 PUPILS SELECTED RANDOMLY FROM 38 SCHOOLS IN ILLINOIS. PUPILS WERE IN GRADES 2, 4, AND 6. MEASURES OF VISUAL PERCEPTION, AUDITORY PERCEPTION, VISUAL-AUDITORY SHIFTING PERCEPTION, INTELLIGENCE, SOCIOECONOMIC STATUS, AND…

A THEORY OF TEACHING SEVERELY HANDICAPPED READERS TO READ BY MODALITY BLOCKING OR NONVISUAL ATK, THE AUDITORY-KINESTHETIC-TACTILE METHOD, RATHER THAN BY STRENGTHENING ALL SENSORY MODALITIES IS REPORTED. INDIVIDUALS WHO SPEAK ADEQUATELY BUT WHO READ INADEQUATELY SUFFER INTERFERENCE FROM THE VISUAL INPUT SYSTEM IN THE LEARNING OF READING. IF THE…

Presented is a test used to measure visual perception ability, which consists of 30 groups of forms that are similar to lines used in forming letters, but do not make letters. They are comparable to nonsense syllables used to simulate words. Each group includes four forms and is numbered. The test was used in Rodenborn's study to determine the…

Two groups of continuing education students were tested using three of Viktor Lowenfeld's tests of visual-haptic perception. The scores from the three tests were added to yield a score which identified an individual's location on Lowenfeld's visual-haptic continuum. The investigation also uncovered scoring problems with two of the tests which had…

This article investigates categorical perception as a phenomenon which can be understood in terms of adaptation level theory. Data from four experiments, two visual and two tactual-kinesthetic, supports the idea that categorical perception is a pervasive characteristic of perceptual organization. (JAZ)

The use of a nonvisual tactual and auditory tutorial method to teach initial reading skills to 16 reading disabled children (ages 7 to 14) was evaluated. The method was shown to be less effective than sighted methods. (DB)
