Infants in more alert states demonstrated significantly higher rates of sucking following sound change. Treating state as a dependent variable revealed that state was not significantly affected by a change in stimulus conditions. (RH)

It has been suggested that the inertia tensor governs many instances of haptic perception. However, the evidence is inconclusive because other candidate mechanical parameters (i.e., invariants) were not or were insufficiently controlled for in pertinent experiments. By independently varying all candidate mechanical parameters, the authors were…

Ivry [Ivry, R. B. (1996). The representation of temporal information in perception and motor control. Current Opinion in Neurobiology, 6, 851-857.] proposed that explicit coding of brief time intervals is accomplished by neurons that are tuned to a preferred temporal interval and have broad overlapping tuning curves. This proposal is analogous to…

If a student's perception of his environment affects his behavior in it, the college should have a measure of it as additional data for educational decisions. This would be added to the student's personal data file already maintained by the college, and used in developing new programs and policies; in self-study; to compare with normative data; to…

Two studies assessed the kinesthetic aftereffect using a wide inducing block with the Petrie measurement procedure and a traditional procedure. The subjects included 76 male and 101 female undergraduates. Aftereffect scores were generally correlated as predicted. (TJH)

Analyzes a method of detecting changes in a particular frequency band by evaluating the overall shape or profile of the auditory signal spectrum. Claims that profile analysis is different from intensity discrimination, and applies the new method to detecting noise sinusoid and to results obtained when signal frequency is uncertain.

Twenty normal-hearing, sighted subjects (ages 20-42) viewed soundless videotapes of a speaker reading lists from the two forms of the Utley Lipreading Test and three from Harris' revised Central Institute for the Deaf (CID) Everyday Sentences. Results do not support the interchange of Utley and CID sentences for test-retest comparisons of…

Four experiments replicated findings that perceiving two terms in a unitary relationship facilitates their association. (Author/ML)

Presents study designed to further evaluate the nature of spoken-language comprehension under conditions of varying perceptual load by manipulating different comprehension conditions. Investigates effects of subsidiary task paradigms on course of simultaneous comprehension processing. Argues that these can only be used when accompanied with probes…

Seven experiments with a total of 480 subjects indicated that subjects visually imaging classical ambiguous figures have difficulty reconstructing the images, and that their construal of the image strongly influences what is depicted within the image. Image content, rather than image inspection, appears to be selective. (SLD)
