Two distinguishing characteristics of speech perception are the rate at which speech can be perceived and the proficiency with which temporal order information is preserved. The present article is concerned primarily with the latter. (Author/RK)

A STUDY OF PERCEPTION USED A SAMPLE OF 325 CEREBRAL PALSIED CHILDREN (211 WERE SPASTIC, 114 WERE ATHETOID) AND 110 NORMAL CHILDREN. ALL CHILDREN WERE BETWEEN SIX AND 16 YEARS OF AGE AND OF NORMAL INTELLIGENCE. TO INVESTIGATE PERCEPTUAL DISTURBANCES, SIX TESTS WERE ADMINISTERED--THE TACTUAL MOTOR TEST, THE SYRACUSE VISUAL FIGURE BACKGROUND TEST…

THE VALUE OF THE ACOUSTIC PARAMETERS OF A PHONETIC EVENT VARY FROM SPEAKER TO SPEAKER AND, TO SOME EXTENT, FROM DAY TO DAY. THE ABSENCE OF STABLE INVARIANTS IN SPEECH PRODUCTION IMPLIES THAT A COMPUTER MUST BE SELF-ADAPTIVE IN ORDER TO RECOGNIZE THE PHONETIC EVENTS OF DIFFERENT SPEECH PRODUCTIONS. SELF-ADAPTATION, HOWEVER, REQUIRES THAT PHONEME…

THE CHANGING ROLES OF THREE VISUAL-SPATIAL ABILITIES (SPATIAL ORIENTATION, VISUALIZATION, AND PERCEPTUAL SPEED) IN THE PERFORMANCE OF GROSS MOTOR SKILLS AT SUCCESSIVE STAGES DURING THE LEARNING PERIOD WERE STUDIED. THE SUBJECTS CONSISTED OF 48 WOMEN, AGES 17 TO 24, WHO WERE EQUALLY ASSIGNED TO EITHER OF TWO SECTIONS AND SUBDIVIDED INTO THREE…

THE PROBLEM OF THE RESEARCH WAS TO STUDY THE RELATIONSHIP BETWEEN PERCEPTION AND COGNITION FACTORS IN THE GROWING CHILD. A CENTRAL TASK WAS TO DEVELOP AN INSTRUMENT FOR ASSESSING THE DEVELOPMENT OF SIZE CONSTANCY IN A PROCEDURE IN WHICH THE EFFECTS OF COGNITIVE ACTIVITY COULD BE EITHER CONTROLLED OR EVALUATED. USING A NUMBER OF CONSIDERATIONS, THE…

This study investigated whether or not there is a significant difference between pupil perceptions of teachers who score high on Shostrom's Personal Orientation Inventory (POI) and pupil perceptions of teachers who score low. The POI was administered to 11 teachers of the fourth, fifth and sixth grades to measure aspects of self-actualization. The…

This experiment asked whether infants at 5 months perceived an invariant over four types of rigid motion (perspective transformations), and thereby differentiated rigid motion from deformation. Four perspective transformations of a sponge rubber object (rotation around the vertical axis, rotation around the horizontal axis, rotation in the frontal…

The first aim of this study was to assess the proportion of students at different levels in a Nigerian secondary school who interpret selected diagrams in 3 or 2 dimensional terms and to see if there are differences between these interpretations and those of English students. (Author/AM)

The short-term reliability and long-term stability of visual habituation and dishabituation in infancy were assessed in a sample of 186 infants from four age groups (3-, 4-, 7- and 9-month-olds) seen for two within-age sessions, and in a sample of 69 infants seen longitudinally at 3, 4, 7, and 9 months of age.

Presents a study which investigated the perception of music majors and nonmusic majors concerning their ability to discriminate the way in which altered musical excerpts differed in pitch or tempo (or both) from preceding presentations. Concludes that both groups responded similarly across conditions and replications, and that tempo changes were…

Investigated the tempo note preferences of 100 randomly selected college-level musicians using familiar orchestral music as stimuli. Subjects heard selections at increased, decreased, and unaltered tempi. Results showed musicians were not accurate in estimating original tempo and showed consistent preference for faster than actual tempo.…

Examines the relationship between home musical environment and musical attributes among 116 second-grade primarily Mexican-American children. Multiple regression analyses revealed no significant relationship between home environment and tonal or rhythmic perception. (Author/JDH)

Attempts to determine (1) the number and nature of perceptual dimensions of tone in Cantonese, Mandarin, and Taiwanese listeners; (2) to what extent individual differences in tone perception are influenced by a Chinese listener's language background, and (3) whether differences in perceptual saliency of dimensions across Chinese languages can be…

There is a conflict in the literature on selective attention. Five experiments were conducted to resolve this conflict, and all involved a comparison of tachistoscopic recognition when alternatives were either presented beforehand or not. (Editor/RK)

Reports the results of studies of perception of very young infants. Sixty infants 6 to 23 days old were presented objects; looking-at and reaching-for the objects were measured. Results indicated active visual exploration of objects did occur; however, little motor activity was directed toward the objects. (SL)
