JOURNAL FREE ACCESSStevens' power law is examined by magnitude estimation method and ratio rating method. Stimuli are nine plastic cylinders weighing from 40 to 200 g. The criteria for prothetic-metathetic dichotomy are discussed in terms of ratio axioms and distribution functions. We find three kinds of biases, corresponding to the axioms, which originated from stimulus presentation procedures. So called ratio scale constructed by direct method cannot be conceived as a ratio scale in its original form, as it will not satisfy the axioms. After the biases are eliminated and the scale values are revised, we obtain power psychophysical equation. Psychological scaling methods are closely related to definitions about distribution function of sensation magnitude. Curvilinear relationship between category scale and ratio scale is an artifact due to the definitions.View full abstractDownload PDF (721K) -

JOURNAL FREE ACCESSIn order to control response latency, goat's leg was subjected to a specifiable external force which produced a passive forward movement of the leg. A shock to the paw was contingent on its passive forward movement of 12 cm. A stimulus (45-watt light, 1200-msec duration) preceded the external force by 200 msec in one session and 1200 msec in another. The amount of inhibition with which S resisted by responding to the stimulus on a trial was obtained from the extent of the passive forward movement of the paw. The results from administration of test stimuli (18, 36, 63, and 100 watts) show that the stimulus intensity effect depends on response latency. The stimulus intensity effect was then interpreted in terms of stimulus intensity-duration reciprocal relationship and response latency.View full abstractDownload PDF (522K) -

JOURNAL FREE ACCESSThe present study is an attempt to investigate the child's number concept from two aspects; namely, the effect of the magnitude of number and several attributes of the stimulus upon the acquisition of number concept. A controlled experimental procedure and a statistical analysis were used in order to standardize the data. 32 boys and 38 girls whose ages varied from six years to six years and five months were tested. The results are as follows; 1. They understand number from small to large. 2. The difference of condition between an equal number of elements and a different number of elements is scarcely found. 3. They are independent of the stimulus attribute, to a certain extent, except in case of a disorderly arrangement. 4. They can not understand the higher level of number concept. 5. The verbal label does not play a role in judging the number of elements.View full abstractDownload PDF (892K) -

JOURNAL FREE ACCESSThrough the application of multidimensional scaling method (Torgerson's procedure), a possibility has been tested and confirmed that the binocular visual space in the sense of Luneburg is describable in terms of Euclidean geometry of appropriate dimensions. In a dark room, 14 small light points were presented in the eye level to the S whose head was fixed but eyes were allowed to move freely to fixate each stimulus point. The S himself was counted as a point in addition to the 14 light points and ratio judgments about apparent interpoint distances of all possible pairs were made and scaled. The apparent interpoint distances were accounted for fairly well within the framework of two dimensional Euclidean geometry. From the correspondence between two configurations, of stimuli in the physical space and of perceived points in the visual space, an attempt was made to deduce theoretical forms of horopters, distance and parallel alleys.View full abstractDownload PDF (556K) -
