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.     

Solution of the intermediate size problem by pigeons

Pigeons learned to respond to the middle-sized member (S^D) of a set of three simultaneously presented stimuli with responses to the S^D reinforced on a VI 1 schedule. They were then tested for several days with other sets of three stimuli. One procedure presented reinforcements on a VI 1 schedule during the test independent of the stimulus chosen when a reinforcement was programmed. The tests were also given under extinction conditions. With the testing carried out with extinction, preference consistently was for the test stimulus most similar in physical size to the S^D. However, when the tests were with reinforcement, random responding resulted. Another effect of testing with reinforcement was an increase in incorrect responding with the training set. Such a test procedure was unsatisfactory for determining the effective aspect of the S^D. The conclusion, based on the data of the extinction series, was that pigeons learned the intermediate size problem on the basis of the discrimination of absolute stimulus properties.     

Escape behavior under continuous reinforcement as a function of aversive light intensity

In 11 male albino rats, lever-pressing responses, maintained under a CRF escape schedule with light as the aversive stimulus, were examined at each of five intensities, viz., 2.5, 18, 105, 190, and 386 ft-C. The function relating reciprocal of latency of the escape response to aversive light intensity passed through a maximum.     

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.

The detection of malingering in neuropsychological assessment

Although malingering, or the manipulation of data by the patient, is a problem commonly faced by neuropsychologists, there has been little systematic investigation of this problem. This paper reviews the literature on the detection of malingering in assessment instruments commonly used by clinical neuropsychologists. Criticism of previous research is discussed, and suggestions are made both for future research and for clinical practice.     

Prevalence of personality disorders among bulimics,nonbulimic binge eaters,and normal controls

We examined the comorbidity of bulimia and personality pathology among college women. Subjects included women (n=23) meeting DSM-III-R criteria for bulimia nervosa (bulimics), women (n=23) who reported binge eating but did not fulfill the criteria for bulimia nervosa (binge eaters), and women (n=23) who did not binge eat (normals). The subjects completed an assessment battery consisting of the Personality Disorders Examination and the SCID as well as the Beck Depression Inventory, the Rosenberg Self-Esteem Index, and measures of impulsivity and self-defeating tendencies. Fourteen of 23 bulimics (61%) met criterion for a personality disorder using DSM-III-R Axis II criteria. In comparison, 3 of 23 (13%) binge eaters and 1 of 23 (4%) normal subjects received an Axis II diagnosis. Borderline and self-defeating diagnoses were the predominant personality disorders in 96% of the bulimics exhibiting clinically significant personality pathology. Bulimics also exhibited significantly more depression, impulsivity, and self-defeating behavior and lower self-esteem than binge eaters and normals. The findings are discussed within a conceptual framework that posits an interaction between personality pathology and restrained eating.
