Weber and Weimar: A response to Factor and Turner

In their critique, Factor and Turner attempt to substitute one commonplace for another by merely supplying long lists of publications that mention Max Weber. While accepting their reproof that I applied the concept of „influence”︁ too narrowly, my response endeavors to map out the directions that further research in this area will need to follow if the controversy is ever to move beyond jejune polemics.     

Eye vergence is susceptible to the hollow-face illusion

When an observer looks at a hollow mask of a face, a normal convex face is often perceived [the hollow-face illusion--Gregory 1973, in Illusion in Nature and Art (London: Duckworth) pp 49-96]. We show that in exploring an illusory face, the eyes converge at the illusory and not at the real distances of fixated targets like the tip of the nose. The 'vergence error' appears even though the resulting disparities of the two retinal images of the target provide feedback that would allow an immediate correction. It is presumably the success of recognising a familiar object (a face) which overrides the correction of convergence. This suggests that the brain strives for a congruency of eye vergence and distance perception.     

The generalization of shared reality: When communication about one target shapes evaluations of other targets

Communicators often tune their message about a target to the audience's attitude toward that target. This tuning can shape a communicator's own evaluation of the target, which reflects the creation of a shared reality with the audience. So far, evidence for shared‐reality creation has been confined to one specific target. In two experiments, we examined whether and when a shared reality would generalize to other targets. In Experiment 1, shared‐reality creation about an ambiguous sexist target generalized to the evaluation of a new ambiguous sexist target for which no audience attitude was provided. However, this happened only when there was high (vs. low) commonality with the audience regarding previous judgments. In Experiment 2, we investigated conditions for the temporal persistence of generalization. One week after message tuning to a high‐commonality audience, a shared reality generalized to a new ambiguous sexist target when participants recalled the shared‐reality creation about the initial target, but it did not generalize in conditions without such recall. Also, no generalization occurred for non‐ambiguous or non‐sexist targets. Results suggest that shared reality generalization depends on perceived commonality with the audience, recollection of shared reality at time of judgment, and similarity between new and initial targets.     

Kandidaten in psychotherapeutischer Ausbildung

In the context of the discussion about a reform of psychotherapeutic training in Germany the question arises, which factors influence the decision of psychologists and physicians for a particular training. 343 candidates in psychodynamic, behavioural or psychoanalytic training were asked about their motives for the training, their professional objectives in general and their satisfaction with their choice of training. The candidates' decision for a particular training was associated with personal attitudes and professional goals, with the given information about psychotherapeutic treatment within their studies and with their field of study. For the most part, the respondents are not satisfied with the quality and quantity of information on psychotherapeutic treatment within their studies. Candidates in analytic training are altogether more satisfied with their choice of training and do not plan to start an additional psychotherapeutic training as often as candidates in behavioral training. The consequences of these results in particular for the medical and psychological curricula (a more balanced representation of psychotherapeutic methods) are discussed.     

What triggers causal attributions? The impact of valence and subjective probability

Various field studies and experimental simulations demonstrated that causal reasoning increases after unexpected as well as after unpleasant events. However, unpleasant events are seen as less likely than pleasant ones in everyday life. Accordingly, the subjective probability of the event and its hedonic quality were naturally confounded in these studies. To isolate the contribution of both determinants, the subjective probability and the valence of an event were independently manipulated in a laboratory experiment. Subjects completed an ostensible ‘professional skills test’ and received either success or failure feedback in relation to a criterion set by the experimenter. The subjective probability of success was varied by informing subjects about the distribution of success and failure in a comparable population (either 23 per cent or 77 per cent were said to meet the criterion). The results indicate a pronounced valence effect: The intensity of causal reasoning and the number of possible reasons reported for the outcome was greater after negative than after positive feedback, independent of the a priori probability of the outcome. No evidence for an increase in causal explanations after unexpected, as compared to expected, events was obtained. Several mediating processes are discussed.     

Self-controlled visual discrimination learning of group-housed dwarf goats (Capra hircus): behavioral strategies and effects of relocation on learning and memory

In most studies on animal learning, individual animals are tested separately in a specific learning environment and with a limited number of trials per day. An alternative approach is to test animals in a familiar environment in their social group. In this study, the authors--applying a fully automated learning device--investigated voluntary, self-controlled visual shape discrimination learning of group-housed dwarf goats (Capra hircus). The majority of the tested goats showed successful shape discrimination, which indicates the adaptive value of an effective learning strategy. However, in each group, a few individual goats developed behavioral strategies different from shape discrimination to get reward. Relocation impairs memory retrieval (probably by attention shifting) only temporarily for previously learnt shapes. The results demonstrate the usefulness of a self-controlled learning paradigm to assess learning abilities of social species in their normal social settings. This may be especially relevant for captive animals to improve their welfare.
