A NOTE ON INTEROCULAR TRANSFER AND THE COLOUR OF VISUAL AFTER-IMAGES

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.     

ON THE ONTOGENETIC DEVELOPMENT OF MORAL CRITERIA

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.     

Meinungsänderung durch eigenes Handeln Die Rückwirkung einstellungskonträrer Agitation

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.

Input- and output-monitoring in implicit and explicit memory

Previous experiments have shown that the procedure of questioning subjects retrospectively about the input and output status of information (input and output monitoring) is a useful method for assessing the awareness states of subjects during implicit and explicit memory tasks. The main purpose of the present study was to investigate whether the previous findings could be extended to other implicit and explicit memory tasks. We were especially interested in whether differences in input- and output-monitoring performance can be observed when both the implicit and explicit memory tasks are conceptual ones. In a final test phase, the target items from the study phase and new distractor items were presented. In a recognition-like situation, subjects had to decide whether an item had been presented in the study phase (input status), as well as whether they had produced the item in the memory-test phase (output status). In all three experiments judgments about the input status - but only for those items that had been produced in the implicit or in the explicit memory test - were more precise after explicit than after implicit memory testings. This finding was not influenced by the distinction between perceptual and conceptual-memory tasks (Exp. 1), and was obtained under conditions in which the implicit and the explicit memory tasks were both conceptual and differed only in test instructions (Exps. 2 and 3). These results suggest that not only subjects performing a perceptual test of implicit memory, but also subjects in a conceptual implicit test were less aware of using information from a previous study episode than subjects who received memory instructions. It is concluded that requiring judgments about the input status of information is a good method for assessing subjects test awareness and is preferable to the use of a questionnaire (Exp. 3). In contrast, in all three experiments no differences were found with the output-monitoring measure between implicit and explicit test conditions.     

Persistent crying and parenting: Search for a butterfly in a dynamic system

The risks and causes of persistent crying in early infancy are discussed on the basis of a study of 61 infants referred to the Munich Interdisciplinary Research and Intervention Program for Fussy Babies for persistent crying between 1 and 6 months of age, and of a community sample of 51 infants of the same age. Particular attention was paid to pre-verbal parent-infant communication, the development of which was interpreted in terms of a dynamic interactional system including both regulatory and communicative predispositions in infants and intuitive competence for supporting infant predispositions in parents. Neither a gut problem nor any other single causal factor was identified for persistent crying in the majority of cases. In contrast, persistent crying was significantly associated with multiple biological and psychosocial risk factors for both parents and infants. Neurological immaturity, difficult temperament and sleep problems in infants, and impaired psychological conditions, limited resources and failures of intuitive competences in mothers were found to threaten the developmental process in infants and give rise to ‘vicious circles’ which were destabilizing the interactional systems. Increased attention to intuitive parental competences is recommended as one effective model for therapeutic interventions.     

Axiomatic justifications of the utility principle: A formal investigation

It is argued that existing axiomatic theories of utility do not provide the utility principle or the principle of maximising expected utility with a formal justification. It is also argued that these theories only put mild constraints on a decision-maker in a decision-context. Finally, it is argued that the prospects are not particularly bright for finding formal non-circular arguments for the utility principle that do not rely on the law of large numbers.     

Good governance,law and social reality: Problematic relationships

This article examines the ways in which the linkage between good governance and economic development has originally developed as alegal discussion constrained by the constitution of the World Bank. This normative character of the linkage has subsequently shaped discussions about good governance. It is here argued that this tends to lead these discussions to focus on selective and normative aspects of the interrelations between economic, political and legal-administrative structures and institutions. While the role of law is increasingly acknowledged in more recent debates and policy statements, law tends to be approached from a normative economic or legal perspective that does not provide much insight into the social significance of law. Too little attention is given to anthropological or sociological approaches to legal pluralism in society. These factors combine to detract attention from the fact that governance issues in reality deal withbad rather than with good governance. Franz von Benda-Beckmann is professor in the department of Agrarian Law of the Agricultural University Wageningen and teaches on law and rural development in Third World states and anthropology of law. He holds a doctorate in law and aHabilitation in anthropology. His primary research interests are issues of property rights and social security in rural development, legal pluralism and legal anthropological theory. This is a revised version of a paper presented in the 1993 RAWOO (Advisory Council for Scientific Research in Development Problems) lecture series.
