A six-month-old infant who can remove a transparent cloth from his hand when it is covered after he grasps a toy may not be able to remove an opaque cover. Alternative interpretations of the phenomenon, that is, degree of bimanual coordination and focus of attention, are discussed. (Author/MB)

It is concluded from the study that the three tests tested are not interchangeable despite the fact that they appear to measure similar perceptual functions. All three tests should be combined in a battery if used for diagnostic purposes. (Author)

A Q sort was used to examine the self percepts and ideal self percepts held by counselors in training at the beginning and end of a quarter in which they received formal instruction. The results indicate no significant difference or change in perceptions of self and ideal self. (Author)

The study investigated whether children assigned to classes for severe oral language handicaps in California by a multidisciplinary diagnostic team exhibit a characteristic Illinois Test of Psycholinguistic Abilities performance profile or a number of distinct profiles. (Author)

The underestimation (righting) of frame-of-reference tilt correlates with the perception of the vertical rod as tilted in the opposite direction (the rod-and-frame effect). The rod-and-frame effect can be thought of as the solution to the problem of the rod's tilt given the perceived tilt of the frame. (Author/PN)

This study was designed to investigate the development of the visual placing response in infants, as well as the visual mediation of the response and texture factors that influence this response during its development. The response was associated with age and apparently developed in two phases. (Author/DB)

Results of two studies were consistent with the view that 3-month-old infants perceive movement in depth during their own movement. They can move to avoid a surface just prior to contacting it. (Author/RH)

Scores of 25 learning disabled students (aged 9 to 13) were compared on five tests: a visual-perceptual test (Coloured Progressive Matrices); an auditory-perceptual test (Auditory Motor Placement); a listening and reading comprehension test (Durrell Listening-Reading Series); and a word recognition test (Word Recognition subtest, Diagnostic…

Supports the hypothesized distinction between Mongol children's visual-motor performance and their correctly perceiving visual designs. (Author/RL)
