What's the difference between psychophysical and psychophysics?
Psychophysical
Definition:
(a.) Of or pertaining to psychophysics; involving the action or mutual relations of the psychical and physical in man.
Example Sentences:
(1) The reports of rod-dominated psychophysical spectral sensitivity from the deprived eye of monocularly lid-sutured (MD) monkeys are intriguing but difficult to reconcile with the absence of any reported deprivation effects in retina.
(2) Questionnaires and psychophysical testing have been used to quantify dyspnea, but there is variability in dyspnea grade from these methods.
(3) An attempt is made to relate the results of auditory psychophysics to the physiology of the hearing mechanism.
(4) Psychophysical results on human colour matching (Stiles & Burch, 1955; Stiles & Burch, 1959) were well predicted from the spectral sensitivities of the monkey cones.
(5) Coombs's theory of data (1952, 1964) and his unfolding theory of preferential choice (1950, 1964) provided the conceptualization of metacognition in this psychophysical task context.
(6) The psychophysical relationships between the objective and subjective magnitudes of lung volume were tested during air breathing and at two levels of hypercapnia (breathing 4% and 6% CO2 in oxygen).
(7) Perimetry is a subjective psychophysical sensory examination.
(8) The results of ecological studies appear to be more consistent that those dealing with "specific" psychosomatic disorders and suggest that man has a general psychophysical propensity to disease.
(9) The overall score obtained for all answers informed about the total psychophysical load.
(10) In the skin regions of high thresholds, on the other hand, practically all psychophysical thresholds were higher than the thresholds of the most sensitive afferent units.
(11) Orientation bandwidths of psychophysical channels in the human visual system were inferred from contrast thresholds for a special class of polar-separable, two-dimensional patterns.
(12) Predictions of the model are compared with recently obtained psychophysical data.
(13) The psychophysical methods of magnitude estimation and cross-modal matching were used on a group of 10 men (M age = 19.6 yr.) and 10 women (M age = 20.2 yr.).
(14) A psychophysical scaling procedure confirmed that the constraints generated tone sequences bearing degrees of perceptual similarity to "real" melodies.
(15) Thus, if intensity coding is based on localized firing rate, this fundamental psychophysical behavior does not result solely from peripheral processes.
(16) In psychophysics as well as in sensory physiology, the response amplitude R is often a power function of the stimulus intensity S over a wide range of S (i.e.
(17) Most studies that measured the magnitude of biomechanical, physiological and psychophysical stresses attempted to define peak work-loads.
(18) This fact, in conjunction with some recent psychophysical findings (Lansford and Baker effect) leads to infer that interocular EOG influences are mediated by other mechanisms, in addition to spread across facial tissues.
(19) The use of psychophysical methods for air pollution applications is illustrated by two studies on effects on sensory functions in smokers and passive smokers.
(20) The reliability coefficients for both the psychophysical variables--measured on Borg's CR-10 scale--and heart rate were high.
Psychophysics
Definition:
(n.) The science of the connection between nerve action and consciousness; the science which treats of the relations of the psychical and physical in their conjoint operation in man; the doctrine of the relation of function or dependence between body and soul.
