Olfactory perceptual learning is a relatively long-term, learned increase in perceptual acuity, and has been described in both humans and animals. Data from recent electrophysiological studies have indicated that olfactory perceptual learning may be correlated with changes in odorant receptive fields of neurons in the olfactory bulb and piriform…

The study compared language-disordered and normal young children (N=49) in ability to interpret emotional meaning from vocal cues of adult speakers. Findings indicated that language-disordered children were less accurate in identifying vocal cues of emotion than were normal children, although their error pattern was not significantly different.…

Presents results of a test of nonmusic majors' ability to remember song titles. Suggests that, although the process of categorization seems to be a basic function of perception, appropriate categorization needs to be learned. Supports the view that music learning, like verbal learning, involves a categorization of stimuli based on holistic…

Nonverbal behaviors as part of the communication process in interpersonal relationships has recently become of interest to therapists. Usual investigations of nonverbal behavior have involved observations and ratings of the subjects' behaviors in interview and conventional treatment situations. The author's interest is in: (1) teaching people…

Composition researchers and teachers grant that the relationship of non-verbal thinking and language plays a crucial role in the writing of fiction and poetry, but they are sometimes reluctant to perceive that non-verbal thinking must, necessarily, be crucial, with different emphases, in the thinking/writing processes of rhetoric. Activities and…

Human recognition behavior is influenced by the phenomenon of shape constancy, which occurs when the shape of an object is correctly perceived regardless of the orientation of the object in space. The research reported here tests the validity of the shape-slant invariance hypothesis, a theoretical formulation of the phenomenon of shape constancy.…

Acetylcholine release in sensory neocortex contributes to higher-order sensory function, in part by activating nicotinic acetylcholine receptors (nAChRs). Molecular studies have revealed a bewildering array of nAChR subtypes and cellular actions; however, there is some consensus emerging about the major nAChR subtypes and their functions in…

The impact of age effects on nonverbal memory for auditory or tactual patterns has been largely neglected in research studies. The effects of age on nonverbal memory were investigated by comparing subjects (N=120), divided by age decades into six groups (N=20), through tests using visual, auditory, and tactual items which were resistant to verbal…

Two experiments examined the effects of reductions in cortical cholinergic function on performance of a novel task that allowed for the simultaneous assessment of attention to a visual stimulus and memory for that stimulus over a variable delay within the same test session. In the first experiment, infusions of the muscarinic receptor antagonist…

Literature dealing with the disadvantaged is cursorily reviewed and questions raised by the literature are considered. Specifically, this study concerns the relationship between social class and the rate of processing of visual information in young children. Although various sources of slowness in learning are mentioned, this study focused only on…

Based on the more general principle that all thinking (including reasoning) is basically perceptual in nature, the author proposes that visual perception is not a passive recording of stimulus material but an active concern of the mind. He delineates the task of visually distinguishing changes in size, shape, and position and points out the…
