This study examined middle and high school students' perceptions of a weeklong science experience with nanotechnology and atomic force microscopy. Through an examination of student self assessments and their writing, the study allowed us to examine some of the issues that may contribute to discrepancies that are seen between European-American and…

Drop jumping has previously been used to measure fast stretch shorten cycle (SSC) ability and stretch load tolerance. To the knowledge of these authors a test does not exist to achieve this in the horizontal direction. The purpose of this study therefore was to estimate the reliability of a new unilateral horizontal leg power test to assess these…

To conduct a series of studies and to provide other researchers with texts that may prove useful in answering a variety of questions about perception in reading, it was necessary for two researchers to create pairs of texts that were different in meaning but were physically different in only one letter. These texts were created by first…

This article introduces a new clinical technique for psychologists who examine children with school problems. The Kinetic School Drawing, a simple variation of the Kinetic Family Drawing, asks the child to draw a picture of himself in school with a teacher and one or two friends to reveal his perception of his role.

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. (Author/BN)

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.…
