Size-distance perception in preschool children

Journal of Experimental Child Psychology, 1979
Abstract Children between three and six years of age matched the “apparent” and “real” size of familiar and unfamiliar objects 3, 6, or 9 feet away. Prior to the experimental sessions, the children were divided into two groups: (a) those who could distinguish the phenomenal from the real sizes of the arcs in the Jastrow illusion (the “Realists”) and (

In Color Perception, Size Matters

IEEE Computer Graphics and Applications, 2012
In designing colors for digital visualization systems. one of the most critical factors is the interaction between size and color appearance. Whereas artists and visual designers understand this, recommendations for using color in visualization rarely address the issue, or even recognize it.

Object Recognition May Distort Size Perception

Perceptual and Motor Skills, 2000
Size estimation may be influenced by characteristics recalled about the object viewed. This study evaluated the influence of object familiarity on estimation of size. We compared size estimates of several familiar objects with size estimates of undefined objects matched for dimensions of pattern and color.

Size Matters: Saccades during Scene Perception

Perception, 2007
We investigated the effect of image size on saccade amplitudes. First, in a meta-analysis, relevant results from previous scene perception studies are summarised, suggesting the possibility of a linear relationship between mean saccade amplitude and image size.

Perception of Size of Movement Patterns

Journal of Motor Behavior, 1979
Physiological data suggest that perception and memory of kinesthesis may differ depending on whether a movement pattern is actively commanded or passively induced. An attempt was made to demonstrate a difference between these two types of movements by employing a cross-modal visual recognition test of size perception.

Perception of Body Size in Schizophrenia

Archives of General Psychiatry, 1962
In an earlier preliminary study, Cleveland 1 found that schizophrenics overestimate body size when making size judgments from photographs of body parts. Moreover, schizophrenics exceeded a hospital control group in size estimates made from photographs of such body parts as a heart and stomach, as well as a hand and foot.

Ballroom Dance and Body Size Perception

Perceptual and Motor Skills, 2014
Ballroom dancing consists in the performance of rhythmic movements guided by music, which provide sensorimotor integration and stimulate feelings. The body schema is the unconscious sensorimotor representation that allows the individual to perceive his anatomical body in space.

Size Constancy and Angular Size Matching in Size Perception of Near Objects

Optometry and Vision Science, 1999
Accurate judgment of the relative sizes of near objects at various distances is important for a variety of occupational visual tasks. This study involved matching the apparent size of each of a series of standard targets, placed at distances between 0.2 and 3 m and all subtending 2 degrees at the eye, with a comparison target of similar geometry, but ...

Plate size does not affect perception of food portion size

Journal of Human Nutrition and Dietetics, 2013
AbstractBackgroundEvidences have suggested that larger utensils may provoke ‘size‐contrast illusions’, influencing the perceived volume and food consumption.ObjectiveTo analyse the influence of plate size on the visual estimate of food portion size.MethodsTwo 400 g portions of pasta with tomato sauce were presented on two plates of different diameters (

Visual perception of changing size: The effect of object size

Vision Research, 1979
Abstract Since marked threshold elevations specific to changing size were produced by rectangular stimuli whose widths were less than 1.5°, but not by wider rectangles we suggest that changing size filters are not sensitive to pairs of edges separated by more than about 1.5°.
