Centering biases in heterochromatic brightness matching
When the method of constant stimuli is used to measure heterochromatic brightness matches, the resulting matches can be strongly biased toward the center of the range of test luminances used. In the present paper, we investigate the source of this centering bias. The stimuli were 2 degrees red squares presented in a gray surround. In the main experiments, two ranges of stimulus luminance were p...
متن کاملHeterochromatic brightness matching with checkerboard patterns.
Heterochromatic brightness matches with checkerboard patterns made up of a white reference and a chromatic test element for various element sizes from 3' to 2 degrees 30' square and with a 5 degrees bipartite field were carried out with a color cathode-ray tube. The brightness-to-luminance (B/L) ratios of six chromatic stimuli were obtained, and the brightness additivity for the mixture of red ...
متن کاملInduction effects for heterochromatic brightness matching, heterochromatic flicker photometry, and minimally distinct border: implications for the neural mechanisms underlying induction.
Brightness induction refers to the finding that the apparent brightness of a stimulus changes when surrounded by a black versus a white stimulus. In the current study, we investigated the effects of black/white surrounding stimuli on settings made between red and green stimuli on three different tasks: heterochromatic brightness matching (HBM), heterochromatic flicker photometry (HFP), and mini...
متن کاملRelative influence of anchoring and centering biases in reconstructive memory
We report the results of an experiment probing the relative influence of centering and anchoring biases in reconstructive memory for line lengths. On each of 90 trials participants (N=120) viewed a target line, which they reproduced after a delay by adjusting a response line. We manipulated the starting size of this response line in three conditions: one provided an anchoring bias opposite the ...
متن کاملInfluence of Luminance Flicker and Purity on Heterochromatic Brightness Matching and Hue Discrimination: A Postreceptoral Opponent Process
We have studied psychophysically the characteristics of the postreceptoral stage of visual processing, using heterochromatic brightness matching (HBM) between 540 and 600 nm, and hue discrimination between 565 and 585 nm, under differing luminance flicker (0-30 Hz) and excitation purity (1.0-0.1) conditions. The HBM curves exhibit deeper minima around 575 nm with decreasing purity. The minimum ...
