Røigaard‐Petersen, H. H., Nissen, Th.&Fjerdingstad, E. J. Effect of ribonucleic acid (RNA) extracted from the brain of trained animals on learning in rats. III. Results obtained with an improved procedure.Scand. J. Psychol., 1968, 9, 1–16.—By modifying several steps in an experimental procedure in which rats are injected intracisternally with an RNA extract prepared from the brain of trained rats, and subsequently tested in the same training situation, high reproducibility is obtained. A detailed description of the procedure is

Strømnes, F. J. The randomized blocks design. A procedure for checking the success of the forming of blocks.Scand. J. Psychol., 1968, 9, 17–18.—A simple check for the success of any particular attempt at making a randomized blocks design is presented. It is proved that evaluation can be performed by comparing the mean square for blocks with the mean square for the residual. If the residual mean square is the greaterone, the randomized groups design might be used in anal

Eriksson, E. S. Two‐dimensional field effects and static slant perception.Scand. J. Psychol., 1968, 9, 19–32.—The model for two‐dimensional field effects as developed in a previous article makes possible certain predictions concerning perceived shape which, taken together with the subjective slant principle, result in predictions of the perceived slant of a circle or a surface composed of circles. Data were obtained which agreed with these predictions, showing that the geometrical shape slant invariance hypothesis is an inadequate model for depth perception. Some implications for gradient theory, Helmholtzian theories and Gestalt theory are di

Ås, A.&Osstvold, S. Hypnosis as subjective experience.Scand. J. Psychol., 1968, 9, 33–38.—Fifty female students were interviewed about their subjective experiences during experimental hypnosis. A majority of the experiences correlated positively with measured depth of hypnosis. A factor analysis suggested three experiential factors, differently correlated with hypnotic d

Smith, G. J. W. Differentiation of psychotic subjects by means of the metacontrast technique.Scad. J. Psychol., 1968, 9, 3–44.—Sixtyeight psychotic patients tested with the meta‐contrast technique (MCT) were divided in six sub‐groups according to focal symptoms. Many sub‐groups clearly differed with respect to MCT results. In the schizophrenic groups serial discontinuity due to regression was particularly prominent; in the paranoid, non‐schizophrenic groups, marked subliminal influence on the frame percept plus other signs of projection. The meaning of psychotic color responses to black‐and‐white stimuli was

Nonaggressiveness induced by defeats in fights did not affect the level of sexual activity as compared with that of the control a

Härnqvist, K. Relative changes in intelligence from 13 to 18. I. Background and methodology.Scand. J. Psychol., 1968, 9, 50–64.—A ten‐percent sample of the Swedish school population born in 1948 took an intelligence test at the age of 13. The male part was tested again at 18 in connection with enrolment for military service in 1966. Complete test scores are available for 4616 men. The data were used to investigate relative changes in intelligence connected with differences in education and home background. In this report the theoretical and statistical bases for such comparisons are analyzed. In part II the results are re

Härnqvist, K. Relative changes in intelligence from 13 to 18. II. Results.Scand. J. Psychol., 1968, 9, 65–82.—Relative changes in intelligence from 13 to 18 are shown to be related to differences in education and to some extent also home background. The relationship is stronger for general intellectual level than for a component contrasting spatial with verbal performance. Alternative interpretations of results are discussed against the background described in Pa

Ekman, G., Fröberg, J.&Frankenhaeuser, M. Temporal integration of perceptual response to supraliminal electrical stimulation.Scand. J. Psychol., 1968, 9, 83–88.—The effect of duration of electrical stimulation on perceived unpleasantness was investigated in 10 subjects. Duration of stimulation ranged from 0.05 to 3.00 sec. Three levels of intensity were investigated representing 2, 3, and 4 times the individual sensation threshold. For all stimulus intensities perceived unpleasantness was a simple logarithmic function of stimulus duration over the whole temporal range. This relation describes the trend of both the group data and the data from most individual subjects. The results support previous findings over a narrower temporal range and agree with results recently obtained in several additional sense modali

Nordenstreng, K. A comparison between the semantic differential and similarity analysis in the measurement of musical experience.Scand. J. Psychol., 1968, 9,89–96.—Ten pieces of music were rated by a group of broadcasting sound‐controllers using two different scaling techniques, the semantic differential ratings of each sound on 32 scales, and similarity ratings for all pairs of sounds. The two scaling techniques were compared matching factor spaces by transformation analysis. The results indicate almost perfect similarity of the factor structures, which suggests that similarity analysis and the semantic differential in fact measure the same
