"The conditionability of the eyeblink response using a photocell method with human infants was explored... The data indicate the feasibility of studying such conditioning in young infants. (Author)

Using an objective measure of attention obtained during a baseline period, assesses in two studies the effects of attention on operant learning among 240 infants 14 weeks of age who were rewarded for kicking with a pattern of lights and tones. (RH)

The internal reliability of the Speech Sounds Perception Test was examined in two independent samples. Both indicated a significantly greater number of errors on the first half of the test; the largest number of errors occurred on Subtests B and A. Reliability coefficients and a performance classification formula are discussed. (Author/CM)

Intraperceptual theories of attention allow for the selective modulation of amount of nonconscious, perceptual processing of concurrent stimuli. Previous research is inconclusive because of the lack of an appropriate measure of perceptual processing. This experiment provides such a measure. The data support a broad version of intraperceptual…

Five experiments are reported concerning the effect on visual information processing of concurrently maintaining verbal information. The results suggest that the left cerebral hemisphere functions as a typical limited-capacity information processing system that can be influenced somewhat separately from the right hemisphere system.

Newborns were presented with a tape-recorded rattle sound through a single loudspeaker, through two loudspeakers with one onset leading the other by seven msecs., and through two loudspeakers simultaneously. Newborns turned toward the single source sound, but not toward either of the dual source sounds. (Author/RH)

The results indicated that normal children experience auditory fusion at shorter time intervals than is true for either of the disabled groups, that signal intensity affects auditory fusion for all groups, and that only the learning disabled children are differentially affected by the frequency of the stimulus tones. (Author/PHR)

The schema hypothesis proposed by Kagan and Lewis was used to make predictions concerning the preferences of infants 3 to 14 months old for speech stimuli. An operant response method was used in determining the infants' preferences for inflected, monotone, and scrambled natural speech stimuli. (MS)

A new procedure for estimating the dichotic ear advantage is applied for the first time in conjunction with the single-response requirement. Most subjects showed unusually large right-ear advantages, making the present methodology interesting for the study of hemispheric asymmetry. (Editor)

Investigates how the inhibition and latency-reduction effects interact with each other and how they change with changes in the intensity of the startle-eliciting stimulus. (Author/RK)

Describes two variants of the form-priming paradigm (direct and mediated form priming) and summarizes the results obtained with each. With both variants, participants are presented with a target, to which a response is required, preceded by a prime. (28 references) (Author/CK)

Notes that phonemic restoration is a powerful auditory illusion. Points out that when part of an utterance is replaced by another sound, listeners perceptually restore the missing speech. Several paradigms measure this illusion and explore its bottom-up and top-down bases. Findings reveal that acoustic properties of the replacement sound strongly…
