Using psychophysical methods, I am also investigating how light and dark stimuli are treated differently in normal and abnormal visual systems.
(19) cannot be made because different psychophysical methods and luminance conditions to measure CSF were used.
We are currently evaluating other psychophysical methods that may trade an acceptable increase in testing time for greater sensitivity.
However, quantitatively precise psychophysical methods are needed to examine those factors most salient to masking and investigate mixture properties with sufficient precision and reliability to enable the development of predictive models and test mechanistic hypotheses.
That research employed psychophysical methods (Kling & Riggs, 1971) to identify the smallest degree of abnormality that individuals could identify, by touch, in breast tissue (Adams et al., 1976; Bloom, Criswell, Pennypacker, Catania, & Adams, 1982).
Presents evidence from available research, clinical reports, and extensive personal experience to demonstrate that hypnosis, and especially the hypnoreflexogenous technique, facilitates the mother's comfort in pregnancy, labor, and delivery; is superior to the use of chemicals or other psychophysical methods as the primary aid in childbirth; and results in lasting benefit for the mother, the child, and the family as a whole.
First, a model of fatigue or inattention could be set forth and simulated to determine whether both psychophysical methods are differentially affected; some progress along this line has been made and very preliminary (but promising) results have been reported by Alcala-Quintana and Garcia-Perez (2004b).
This result agrees with the results of our previous studies (Higashiyama et al., 2001; Higashiyama & Shimono, 2004), in which scales for distance were obtained by three psychophysical methods. For each method used, the exponent of power function was smaller in convex mirrors than in a plane mirror (0.89 against 0.95 for the partition method; 1.36 against 1.43 for the method of magnitude production; 0.88 against 1.03 for the method of magnitude estimation).
The benefits of using psychophysical methods to assess exposure to forceful exertions are numerous.
Although, as we shall see, the LBW decision is suitable for study by psychophysical methods, it poses one particular problem of its own, namely, the large dimensionality of the stimulus.
