Psychotherapie und Internet

Zusammenfassung  Die Außendarstellung im Internet ist wichtig und in der Zukunft unverzichtbar. Jedoch hat die Liberalisierung des Werberechts der freien Berufe keineswegs zur absoluten Schrankenlosigkeit geführt. Vielmehr sind die zu beachtenden Regeln auf verschiedene Gesetze und Rechtsgebiete verstreut, so dass ohne fachkundige Hilfe—etwa durch die Kammern oder durch juristische Beratung—die Selbstdarstellung im Internet schnell zu einem bösen Erwachen führen kann.

Symmetry axiom of Haken–Kelso–Bunz coordination dynamics revisited in the context of cognitive activity

We present an axiomatic derivation of a model proposed by Haken, Kelso, and Bunz (1985) that describes dynamical aspects of the rhythmic coordination between two limbs. Elaboration of this model has included a symmetry parameter that captures the coordination consequences of an inherent or imposed frequency difference between the limbs. We modified one of the axioms involved in the model derivation, a symmetry axiom, in order to incorporate a new symmetry parameter. This new parameter defines a shift between (a) the laboratory coordinate system, in which the behavior is observed, and (b) a second, postulated coordinate system. It is this second coordinate system, in which the relevant state dynamics is assumed to take place and in which the state dynamics evolves under the impact of an attractor. The state dynamics as described in the attractor coordinate system is then mapped by means of the new symmetry parameter to the laboratory coordinate system. We discuss analytically the bifurcation diagram of the model and determine main effects and interaction effects of manipulations related to the symmetry parameters and related to the mode of coordination (in-phase and anti-phase). The theoretical results are brought to bear on the challenging experimental observation that concurrent cognitive activity (counting, encoding, retrieving, sentence analysis) changes the location of the bimanual coordination attractor but not its strength. The theoretical results suggest that cognitive activity may have the effect it has because it shifts the attractor coordinate system relative to the laboratory coordinate system.     

Hypnotic experience and the autism spectrum disorder. A phenomenological investigation

In recent decades, the focus in autism research progressively expanded. It presently offers extensive material on sensorimotor disturbances as well as on perceptive-cognitive preferences of people with autism. The present article proposes not only a critical interpretation of the common theoretical framework in autism research but also focuses on certain experiences common to some people with autism and which can be appropriately understood by phenomenology. What I will call “hypnotic experiences” in autism are moments in which some individuals withdraw into intense sensorial and perceptive experiences. Following their examples, I use the term “hypnosis” primarily to describe a trance state in which the individuals become highly alert to and awake for an experience of a totally new kind. Through a close analysis of autobiographical writings from people with autism I defend the idea that the particularity of hypnotic experiences in autism consists in a certain qualitative shift within experience itself: what changes, in the hypnotic moments, is the way a person with autism relates to his/her own bodily experiences. If this qualitative shift is indeed difficult to account for within a reifying and intellectualist research perspective, phenomenology offers a large conceptual framework for understanding it. Phenomenology, and precisely, phenomenological psychopathology, will thus emerge as a major device in accounting for such “hypnotic experiences”. The argument mainly draws on the twofold structure of experience which is traditionally used in phenomenological research: it claims that in hypnotic experience people with autism are inclined to focus on non-reified “sensings”, “perceivings” and “movings”, and thus leave aside the object itself and any intentional reification of it. Finally, I will claim that this restriction to mere non-reified sensings might lead to a completely new conception of self and world. In the hypnotic experiences of autism, neither the subject nor the object come to a full-blown and independent existence. A thorough phenomenological analysis of hypnotic experience in autism therefore also has to face the question of a corresponding ontology of these experiences.     

Preference change and conservatism: comparing the Bayesian and the AGM models of preference revision

Richard Bradley’s Bayesian model of preference kinematics is compared with Sven Ove Hansson’s AGM-style model of preference revision. Both seek to model the revision of preference orders as a consequence of retaining consistency when some preferences change. Both models are often interpreted normatively, as giving advice on how an agent should revise her preferences. I raise four criticisms of the Bayesian model: it is unrealistic; it neglects an important change mechanism; it disregards endogenous information relevant to preference change, in particular about similarity and incompleteness; and its representational framework, when expanded with similarity comparisons, may give misleading advice. These criticisms are based on a principle of conservatism, and on two proposals of similarity metrics for the Bayesian model. The performance of the Bayesian model, with and without the similarity metrics, is then tested in three different cases of preference change, and compared to the performance of the AGM model.     

On a three-valued logical calculus and its application to the analysis of the paradoxes of the classical extended functional calculus

A three-valued propositional logic is presented, within which the three values are read as ‘true’, ‘false’ and ‘nonsense’. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.     

A reversal of the search asymmetry favouring negative schematic faces

Quite a number of studies have tested whether the affective valence of stimuli can guide attention in visual search. Studies using schematic affective faces frequently found a relative search asymmetry (RSA), with more efficient search for a negative face in a friendly crowd than vice versa. Whether, however, this effect relates to differences in affect or to the confounded differences in perceptual features is unknown. The present study proposes and tests a similarity-based account for the RSA. Experiments 1a and 1b first replicate the typical RSA. Experiment 2 shows that the stimulus could be simplified to some degree without losing the RSA. Experiments 3 and 4, finally, demonstrate that the RSA could be reversed by a rather simple stimulus change, that leaves the facial expression intact. It is concluded that the strong dependence of the RSA on stimulus factors seriously questions the claim that emotional factors drive the RSA.

Effects of cooperation and competition on responsibility attribution after success and failure

Pairs of Ss cooperated (Experiment I) or competed (Experiment II) in a response-matching task whose outcome either exceeded (Success condition), met (Neutral condition), or did not reach (Failure condition) a prior-established expected outcome level. Afterwards, Ss attributed responsibility for their outcomes. It was found under both cooperation and competition that neutral outcomes tended to produce situational attribution, and success produced self-attribution. However, failure produced partner attribution under cooperation but situational attribution under competition. The results were discussed from the standpoint of two general theories of responsibility attribution, the first emphasizing problem solving based on cues, and the second emphasizing motivational biases.     

Examination of efficacious,efficient, and socially valid error‐correction procedures to teach sight words and prepositions to children with autism spectrum disorder

Prior research shows that learners have idiosyncratic responses to error‐correction procedures during instruction. Thus, assessments that identify error‐correction strategies to include in instruction can aid practitioners in selecting individualized, efficacious, and efficient interventions. The current investigation conducted an assessment to compare 5 error‐correction procedures that have been evaluated in the extant literature and are common in instructional practice for children with autism spectrum disorder (ASD). Results showed that the assessment identified efficacious and efficient error‐correction procedures for all participants, and 1 procedure was efficient for 4 of the 5 participants. To examine the social validity of error‐correction procedures, participants selected among efficacious and efficient interventions in a concurrent‐chains assessment. We discuss the results in relation to prior research on error‐correction procedures and current instructional practices for learners with ASD.     

The Interdisciplinarity of Collaborations in Cognitive Science

We introduce a new metric for interdisciplinarity, based on co‐author publication history. A published article that has co‐authors with quite different publication histories can be deemed relatively “interdisciplinary,” in that the article reflects a convergence of previous research in distinct sets of publication outlets. In recent work, we have shown that this interdisciplinarity metric can predict citations. Here, we show that the journal Cognitive Science tends to contain collaborations that are relatively high on this interdisciplinarity metric, at about the 80th percentile of all journals across both social and natural sciences. Following on Goldstone and Leydesdorff (2006), we describe how scientometric tools provide a valuable means of assessing the role of cognitive science in broader scientific work, and also as a tool to investigate teamwork and distributed cognition. We describe how data‐driven metrics of this kind may facilitate this exploration without relying upon rapidly changing discipline and topic keywords associated with publications.
