Many people erroneously believe that an object carried by another moving object will, if dropped, fall in a straight vertical line. This belief may stem from a perceptual illusion in which objects dropped from a moving carrier are perceived as falling straight down or even backward. (Author/RD)

The relationship between vision and mental functioning was investigated in a study of 295 elderly residents from three levels of care. Visual acuity and mental status were assessed. Findings indicate that there was indeed a relationship between vision and mental status. (Author)

This paper reviewed briefly the major types of masking effects obtained with various methods and the major theories or models that have been proposed to account for these effects, and outlined a three-mechanism model of visual pattern masking based on psychophysical and neurophysiological properties of the visual system.

Gaze at objects, another person, and background was measured for 15 days which constituted five different experimental groups in which task and situational factors were varied. Background stimuli had an unreliable effect on gaze. A simple object attracted a great deal of gaze and reduced gaze at the other person. (Author)

Evaluated with two groups of 35 children (median age 12 years) either having or not having school learning and visual perception problems was the sensitivity of human figure drawings in measuring the emotional effects of visual perceptual training of children with visual perceptual problems. (DB)

High intensity discharge lighting sources share the compactness and beam controllability of incandescent sources, but are far more efficient and longer-lived. They share the efficiency and long life of fluorescent sources, but are compact and optically controllable, and are available in higher wattages. (Author/MLF)

Preschool and third grade children matched the orientation of stimuli tachistoscopically presented at times individually set to achieve about 75 percent correct performance. Preschoolers showed no superiority on left versus right while third graders showed significant top and right superiorities. Results are compared with those for adults on the…

This paper describes a theoretical framework for the investigation of some specific types of visual learning difficulties commonly experienced by biology undergraduates. The framework was developed based on the findings of three simple qualitative pilot studies. A variety of neurological, cognitive and cultural mechanisms can influence what humans…

This research investigated three elementary preservice teachers' perceptions of elementary science teachers. Three questions guided this investigation. What images did elementary Masters of Arts in Teaching (M.A.T.) interns have of science teaching at the beginning and end of science methods courses? What changes, if any, did they make in their…

Reports a study indicating that an informal program of training in visual perception was equivalent to a formal program both in producing better results on a visual perception measure and on a reading achievement test. (TO)

Studied influences of simultaneously and successively exposing kindergarten and elementary children to low and high speed motion pictures on their judgment of distance, synchroneity, and isochronism. Concluded the presence of tau and kappa-movement effects in the younger group and anti-kappa effects among the older group. (CC)

The purpose of the experiment was to ascertain whether the duration of the spiral illusion could be extended by a 'learning procedure' which would distinguish a longer-term learning effect from short-term adaptive changes due to inhibition. (Author)

Findings from an experiment designed to discover if color could improve learning from television. (Author/HB)

The relation between type of label and perception of faces was assessed in second- and sixth-grade children. Labels associated with color increased color perception, whereas labels based on expressiveness increased differentiation of expression variations, but not color perception. (ST)
