    As a control experiment to (III) Multi-dimensional scaling (MDS) of distance matrix constructed indirectly from haptic differential profiles, the following data were analyzed by MDS model of Torgerson. (C) Direct estimation of similarities (DES)-touch with vision, (D) DES-vision only, (E) DES-concept only, and (F) indirect scaling of similarity from semantic differential profiles, among 25 samples of various material.
    Results; All MDS yielded very similar configuration of vectors. Metals and stones cluster at the one pole, while fibers and papers at the opposite pole. Results of (III) and (F) are similar, while the other three give slightly different configurations from the above two.

  • RESPONSE LATENCY DEPENDS ON RESPONSE SPEED

    8 groups of Ss tried to push a plate coupled to a weight (500 or 1, 000gm) to an indicated distance (5 or 25cm) at a pace determined by the speed of a belt (37.2 or 7.74cm/sec) operated through an adjustable-speed motor. After 10 such trials, each S was to push the plate for 10 more trials, trying to keep pace with the other speed of the belt than previously used, while all other conditions were kept the same. It was found that response speed is a powerful variable in determining response latency. Implications of this finding were then discussed.

    Twelve sets of directly obtained hue-discrimination thresholds, from König up to Weale, were plotted in a figure and a representative curve as a function of wavelength was determined. With this curve, 3 sets of theoretical thresholds were compared, one derived from multidimensional scaling by Shepard with Ekman's data, one from multidimensional scaling by Shepard and Carroll with Boynton and Gordon's data, the other from the opponent-colors theory by Hurvich and Jameson. Except for a few points, those indirectly obtained thresholds were in good agreement with the representative curve. The same kind of comparison was made in regard to hue-coefficients, according to the terminology of Hurvich and Jameson. Seven sets of hue-coefficient curves, each consisting of 4 curves for red, yellow, green, and blue, and also the theoretical curves of the opponent-colors theory were plotted in a figure. The 7 sets consisted of the curves derived from some of the above-mentioned experimental data and of the curves obtained in color naming experiments by Schouten. Though it was rather difficult to assess the agreement among the sets, all exhibited about the same patterns.

  • DIFFERENTIAL EFFECTS OF CHLORPROMAZINE UPON PASSIVE AVOIDANCE RESPONSE IN RATS UNDER TWO TYPES OF SHOCK TREATMENT

    Chlorpromazine at 2mg/kg, i.p. was shown to inhibit the rat's passive avoidance response in a two-compartment apparatus when the rat was given unescapable electric shock, being confined in the small compartment, while the same effect failed to appear when the rat, placed in the large compartment, received electric shock only upon attempting to enter the small compartment and thus the shock was escapable. A slight but nonsignificant drug-learning dissociation appeared in the “confinement shock” rat. 17 min after the two-compartment training, the rat was observed spontaneous activities in an open-field but no clear-cut differences were found between two types of shock treatment, or between saline and chlorpromazine medication.
