Functional communication during signaled reinforcement and/or extinction

Schedule thinning following functional communication training (FCT) can increase treatment feasibility. Multiple‐schedule arrangements are often used in this process; however, the current literature provides little information on the optimum signal arrangements. In the current study, we examined the effects of three signal arrangements (i.e., signaled FR1, signaled EXT, and signaled FR1/EXT) on rates of problem behavior at dense schedule values and during schedule thinning. At all schedule values, signaled FR1/EXT controlled collateral behavior better than did signaled FR1 or signaled EXT. Additionally, for the single signal arrangements, the signaled FR1 was more efficient than the signaled EXT at dense schedules whereas the inverse was true at leaner schedules.

Just how stable are stable aesthetic features? Symmetry,complexity, and the jaws of massive familiarization

Using both group- and individual-level analyses, we explored the complex and dynamic effects of basic visual features on aesthetic judgment. Specifically, the mediating influence of familiarization on the combined effects of complexity and symmetry on aesthetic judgment was examined. Experiment 1 showed that symmetry and complexity are indeed powerful determinants of aesthetic judgment. Experiment 2 demonstrated that massive familiarization generated contrast effects for complexity: participants familiarized to simple stimuli subsequently judged complex stimuli more beautiful and participants familiarized to complex stimuli subsequently judged simple stimuli more beautiful. In contrast, moderate familiarization in Experiment 3 did not elicit the above effects. Group-level analyses were augmented with judgment analyses of individual response patterns resulting in a more comprehensive assessment of aesthetic judgment.     

Coordinating the effects of multiple variables: A skill fundamental to scientific thinking

The skill of predicting outcomes based on simultaneous effects of multiple factors was examined. Over five sessions, 91 sixth graders engaged this task either individually or in pairs and either preceded or followed by six sessions on the more widely studied inquiry task that requires designing and interpreting experiments to identify individual effects. Final assessment, while indicating a high level of mastery on the inquiry task, showed progress but continuing conceptual challenges on the multivariable prediction task having to do with understanding of variables, variable levels, and consistency of a variable’s operation across occasions. Task order had a significant but limited effect, and social collaboration conferred only a temporary benefit that disappeared in a final individual assessment. In a follow-up study, the lack of effect of social collaboration was confirmed, as was that of feedback on incorrect answers. Although fundamental to science, the concept that variables operate jointly and, under equivalent conditions, consistently across occasions is one that children appear to acquire only gradually and, therefore, one that cannot be assumed to be in place.     

Ausbildungs- und Berufserfahrungen älterer Psychoanalytiker

Based on the discussion about the crisis of psychoanalysis and in particular of psychoanalytic training, 145 (female and male) analysts older than 70 years of age were interviewed about their training and professional experiences as well as about their attitudes towards psychoanalysis. This older generation is of great interest because their training generally took place prior to 1967 and preceded the introduction of guideline therapy (cost coverage by the general health insurance) and under much less formalized conditions, which can be seen almost as a contrast to the current circumstances and conditions. This research has shown that especially personal or content and value-based motivations (personal problems, therapeutic experience, interest in the subject, the desire for depth, self-realization and expansion of the situation perceived as restrictive of their former profession) were the main determining factors for the choice of career. The training analyses were, despite some exceptions, of substantial length even then (an average of 544 h), but often had a lower frequency (30% had less than 3 h per week). Since the age limitation for running a psychoanalytic practice within the general health services (formerly 68 years) is no longer compulsory, the results of this study regarding the professional life of older psychoanalysts are of special interest. Of the respondents 45% are still running their own practice and 22% are working as training analysts.     

A constraint on comparisons: Equally detailed alternatives

Children's errors in collective comparison tasks are atributed to the comparison of the wrong classes. It is specifically hypothesized that alternative classes are erroneously formed subject to the constrain that the same kinds of properties are criterial for each alternative. This hypothesis, called the equally detailed alternatives hypothesis, is tested in three experiments with hierarchically organized stimuli and requests to compare a superordinate class and a nonincluded subclass, for example, dogs and yellow cats. In all three experiments 4-year-old children's comparisons were found to be in accord with the hypothesis. In the first experiment both perceptual and linguistic factors determine which classes are compared. In the second experiment, as predicted, erroneous subclass comparisons were more common when all subclasses were distinguished by the same kinds of properties. In the third experiment, the children were asked to partition the stimulus objects into the classes to be compared. The vast majority of partitions were erroneous and in accord with the hypothesis. Potential benefits of the constrain are considered.     

Der Ideologiebegriff bei Marx und die heutige Kontroverse über Ideologie und Wissenschaft in den sozialistischen Ländern

Marx and Engels inherited and developed the 18th Century notion of ideology as distorted consciousness. Although they did not speak explicitly of a ‘proletarian ideology’, they did develop the elements which Lenin then elaborated. His failure to develop a theory of ideology has left this task to contemporary Marxists (e.g., Althusser) and Marxist-Leninists (e.g., Choruc), who often do this in the process of criticizing non-Marxist theories. A lively discussion took place in the 1960's in Poland (Schaff and Bauman) and in the Soviet Union (Jadov and Julina). One of the results has been to cast doubt on the systemic validity of the principle of party-mindedness (partijnost').
