Following monocular fixation of a red stimulus figure on a grey background, a projection field having the same colour as the stimulus figure was viewed either with ( a ) the stimulated eye, or ( b ) the non-stimulated eye. In case ( a ) the after-image appeared grey on a red background, but in case ( b ) green or blue, on a red background. In the latter case the brightness and to some extent the hue of the after-image varied when the amount of light coming to the originally stimulated eye varied. The data are in agreement with the assumption that after-images are primarily retinal. 相似文献

Changes in the dimensionality of the moral criteria, i.e. of those aspects of an action-sequence to which a person pays attention when judging how good/bad (nice/naughty) the agent is, were studied with 7-, 10-, and 13-year-old girls and adult subjects. Action sequences varying in respect to potential moral criteria were presented as cartoons. A proximity setting technique and Kruskal's (1964) method of analysis were used. In the younger age groups a remorse-spite-dimension was obtained, the motive criterion becoming more dominant and differentiated with age. Methodological problems are discussed. 相似文献

Zusammenfassung Zur Klärung der Frage, ob und unter welchen Umständen einstellungskonträre Agitation auf den Agitator zurückwirkt, wurden Gruppen- und Einzelversuche durchgeführt. Als Versuchspersonen dienten insgesamt 409 männliche und weibliche Oberschüler und Studenten. In allen Versuchen mußten die Versuchspersonen Reden erfinden und halten. Die Messung der Meinungsänderung und einiger hypothetischer Variablen wurde mit Fragebogen vorgenommen, zum Teil wurden nach den Versuchen Interviews durchgeführt.Wir erhielten folgende Hauptergebnisse: Erfinden und Vortragen von Argumenten für einen zudiktierten Standpunkt führen, unabhängig voneinander und von der im Vortrag enthaltenen Argumentation, zu einer Meinungsänderung. Ihre Richtung und ihr Ausmaß sind außerdem abhängig vom Verhältnis der zudiktierten Stellungnahme zu anderen, bereits vorhandenen psychischen Inhalten — starke Verankerung der ursprünglichen Meinung führt zur Meinungsänderung im Gegensinne der Agitation (Bumerang-Effekt) — sowie vom Grad der Willentlichkeit der Handlung: bereits die Entscheidung, einen einstellungskonträren Standpunkt nach außen zu vertreten, kann zu einer Meinungsänderung führen. Das Lernen der Argumente, die Bewertung der eigenen Leistung, des Versuchs und Versuchsleiters sowie Eigenschaften eines Themas für sich erweisen sich nicht als alleinige Bedingungen der Meinungsänderung.Diese und andere, weniger wichtige Ergebnisse werden diskutiert. Die Theorie der kognitiven Dissonanz wird als beste einheitliche Erklärungsgrundlage der empirischen Befunde angesehen.

Summary Experiments with groups and single persons were conducted to test the effect of persuasive behaviour on the communicator. 409 male and female high-school and university students served as subjects. In all experiments the subjects had to invent and verbalize speeches contradicting their own opinion. Opinion change and some hypothetical variables were measured by questionnaires, the sessions were partially followed by interviews.Main results: Inventing or speaking of arguments in favour of an appointed opinion lead, independently of each other and of the informational content of the arguments, to opinion change the direction and magnitude of which are, in addition, dependent on the relation of the argument to previously existent mental contents (if the original opinion is strongly anchored, the persuasive behaviour results in a boomerang effect), as well as the degree of volition of the subject's persuasive behaviour. (Already the decision to defend a point of view contrary to one's own may lead to opinion change). Learning of arguments and evaluation of own achievement, of the experiment and the experimenter as well as the qualities of a topic in itself cannot be shown to be the only conditions of opinion change.These and other, less important results are discussed; the theory of cognitive dissonance is considered the best uniform explanation of these empirical results.

An automated system for measuring intracranial self-stimulation behavior is described. The system consists of two Commodore 6502 microcomputers interfaced with a constant-current generator and a standard operant chamber. The system hardware allows sine- and square-wave stimulation. Stimulus intensity can be varied in 256 steps between 0 and 100, 0 and 500, or 0 and 1,000 /µA. The system programs, which are written in machine language, allow the control of various schedules of reinforcement, the counting of operant responses and reinforcements, the measurement of interresponse intervals, and the storage of the data on disk. The software is designed for the determination of the threshold of reinforcement, on the basis of the titration of postreinforcement pauses caused by changeover in schedule control between concurrent continuous reinforcement and fixed ratio schedules. 相似文献

The Hand Test was administered to 98 severely behavior handicapped (SBH) children and a matched control group of public school children. The withdrawal score and associated variables, indicative of severe psychopathology, differentiated the two groups. In addition, a qualitative analysis of the SBH protocols tentatively suggested a preponderance of four behavioral types that could be described as the underproductive, perseverative, psychotic and impulsive child. Implications of these findings are discussed. 相似文献

Modification of Restle's theory (1970) explains the moon illusion and related phenomena on the basis of three principles: (1) The apparent sizes of objects are their perceived visual angles. (2) The apparent size of the moon is determined by the ratio of the angular extent of the moon relative to the extents subtended by objects composing the surrounding context, such as the sky and things on the ground. (3) The visual extents subtended by common objects of a constant physical size decrease systematically with increasing distance from the observer. Further development of this theory requires specification of both the components of the surrounding context and their relative importance in determining the apparent size and distance of the moon. 相似文献

This research examines the expression of positive and negative emotions under minimally social conditions. Male and female encoders were covertly videotaped while they viewed and made written ratings of their responses to a number of slides, using a list of emotion terms derived from members of the same subject pool. Results show that, even when the social nature of the situation is reduced to a minimum, the experience of some emotions is reflected on the face, and there is clear evidence for differential expression of certain positive emotions. However, the reduced social nature of the situation removes the usual female encoding advantage, supporting the suggestion that this reflects the operation of display rules. The ability to recognize the minimal expressions in this study is related to both gender and emotion type in ways that may be explained by a socialization hypothesis.I wish to thank Gill Thorpe and Eiko Mori for running the decoding subjects of this study, and Sylvie Collins, Tony Manstead, and two anonymous reviewers for comments on an earlier version of the paper. 相似文献
