Defines holography, identifies visual factors in driving and the techniques used in on-road visual presentations, and presents the design and testing of a holographic system for driver training. (RAO)

Visual pattern preferences were established for 96 9- and 13-week-old infants using stimuli varying in contour density presented either at a low, moderate, or high luminance level. Age differences in the maximally preferred patterns across stimuli and luminance levels indicated that luminance interacts with contour density in determining stimulus…

Children listened to a fairy tale and were then asked to draw a picture that the story brought to mind. It was hypothesized that hearing a fairy tale would stimulate archetypal images, rather that the action-related scenes that might be prompted by reading it. (SB)

The ability of forty 8-week-old infants to discriminate between projected-stereograms with and without retinal disparity was tested with an habituation-dishabituation paradigm. Results were interpreted as indicating that the infants could discriminate between stimuli when the only difference between them was binocular disparity. (MS)

Three experiments, employing conditioned suppression in rats, examined the extent to which pretraining on one element of a compound stimulus blocked conditioning to the other element when some feature of the reinforcer was changed on compound trials. (Editor)

The research reported here was directed at evaluating whether or not the effectiveness of a Pavlovian unconditioned stimulus (US) in promoting associative learning is reduced if the US is shortly preceded by another occurrence of the same US. (Author)

By using the concept of modalities (learning processes involving the auditory and/or visual realms) systematically, a teacher may be sure that all modality tasks are covered and that reading weaknesses and strengths are discovered. (MB)

Recent data indicate that the form of the conditioned response (CR) may often be substantially influenced by the characteristics of the conditioned stimulus (CS) as well as by those of the unconditioned stimulus (US). Here five experiments examine the influence of CS characteristics on the form of the Pavlovian CR anticipatory to a food US in…

Sequences of seven tones were presented, and recognition memory for individual tones of each sequence was tested under varying degrees of context. (Editor)

Demonstrates that categorization of speech sounds can be influenced by the phonetic structure of connected speech. (Editor/RK)

This article is concerned with the perceptual load in searching for a number of kinds of target which are presented for a fixed, short period of time. The aim is to establish data which any acceptable model of human information processing will need to fit. (Author)

Repeated, isolated presentations of a stimulus typically reduce the subsequent ability of that cue to become an effective conditioned stimulus. This phenomenon is known as the latent inhibition effect. Four experiments investigate this effect. (Editor/RK)

If the N1 wave (amplitude component between 80-130 msec) does not serve as an index of an initial stimulus set stage of selection, the N1 amplitudes should be differentiated between channels whether the selection is based on pitch, spatial position, intensity, or cues that lead to an efficient rejection of unwanted information.
