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…

Investigates influence of three variables--sex of stimulus person, sex type of subject, and sex of subject--on ratings of the social perception of anger expression. Finds that the variables were important predictors of perceptions of anger, and that type of anger response unexpectedly influenced ratings. (MW)

The specific intention of this study was to determine whether samples of disadvantaged students showed positive self-images (as had been shown by some of previous researches) and whether these are maintained when disadvantaged children move out of their neighborhood schools to the more integrated environment of the high school. Seven hundred and…

Discussion of stereoscopic and planoscopic diagrams as they relate to the level of understanding in depth relationships. Findings indicate a significantly lower understanding in stereoscopic diagrams when compared to a real three-dimensional situation. (JEG)

The project's purpose was to determine whether attention to the task during testing was a confounding variable in measures of visual perception ability. Samples of 30 perceptually handicapped (PH) and 30 normal subjects (N) were randomly selected from children so classified on the Frostig DTVP, providing they had IQ scores between 85 and 115 on…

Grade level norms were developed, based on a sample of 678 elementary school students, for various error scores of the Benton Visual Retention Test. Norms were also developed for 201 normal children, 58 minimal brain dysfunction children, and 101 educable mentally retarded children. In both the copying mode and the memory mode, most errors were…

Compares the format frequencies of the six basic Russian vowels as spoken and perceived by native speakers from Moscow, Minsk, and Kiev. Three experiments examine (1) perception of artificial vowel stimuli; (2) production of vowels from three dialect groups; and (3) dialectal perception of an English vowel. (LMO)

A study was conducted to investigate the comprehensibility of microcomputer-generated color graphics that are displayed on monochromatic monitors. Subjects were 64 second, third, and fourth graders who were randomly assigned to one of two conditions. Children in the first treatment were asked to identify, on a monochrome monitor, a figure that was…

The purpose of this study was to adapt the Hidden Figures Test (a measure of field dependence/independence) to microcomputer display and to assess its alternate form reliability when compared to a paper and pencil test. Participants included 58 undergraduate and graduate students (91.4% female) at a southeastern university who were fairly normal…

The effects of various rates of presentation were studied in combination with massed and spaced, concurrent and nonconcurrent, overt and covert practice modes on film-mediated perceptual performance. Selected values of the independent variables were investigated within a 3x3x2 factorial design, and the experimental treatments were randomly ordered…
