Scientific Revolutions without Paradigm-Replacement and the Coexistence of Competing Paradigms: The Case of Generative Grammar and Construction Grammar

In the Kuhnian and Post-Kuhnian Philosophy of Science, it is widely accepted that scientific revolutions always involve the replacement of an old paradigm by a new paradigm. This article attempts to refute this assumption by showing that there are paradigm-constellations that conform to the relation of a scientific revolution in a Kuhnian sense without a paradigm-replacement occurring. The paradigms investigated here are the linguistic paradigms of Generative Grammar and Construction Grammar that, contrary to Kuhn’s conception of a sequence of paradigm-replacements, are reconstructed as coexisting competing paradigms. By choosing linguistic paradigms, Kuhn’s assumption that paradigm-led research takes place only in the natural sciences is implicitly challenged, and an insight into linguistic theory-construction largely underrepresented in the philosophy of science is given.     

Differential neuronal responses to the self and others in the extrastriate body area and the fusiform body area

The extrastriate body area (EBA) and the fusiform body area (FBA) are selectively activated by viewing human bodies. However, the role of these functionally defined brain areas in self-other discrimination is still unresolved. Thirty-one females were presented with 16 pictures of their own body and another body in a bikini and with scrambled images while fMRI was performed. Moreover, standardized stimulus material was used in order to localize the EBA and FBA. Region-of-interest analysis showed an enhanced BOLD response to the self-images relative to the non-self-images in the right EBA and FBA. The right EBA and FBA are activated differently by viewing oneself and others and might thus play a role in visual self-other discrimination.     

Using Dynamic Field Theory to extend the embodiment stance toward higher cognition

The embodiment stance emphasizes that cognitive processes unfold continuously in time, are constantly linked to the sensory and motor surfaces, and adapt through learning and development. Dynamic Field Theory (DFT) is a neurally based set of concepts that has turned out to be useful for understanding how cognition emerges in an embodied and situated system. We explore how the embodiment stance may be extended beyond those forms of cognition that are closest to sensorimotor processes. The core elements of DFT are dynamic neural fields (DNFs), patterns of activation defined over different kinds of spaces. These may include retinal space and visual feature spaces, spaces spanned by movement parameters such as movement direction and amplitude, or abstract spaces like the ordinal axis along which sequences unfold. Instances of representation that stand for perceptual objects, motor plans, or action intentions are peaks of activation in the DNFs. We show how such peaks may arise from input and are stabilized by intra-field interaction. Given a neural mechanism for instantiation, the neuronal couplings between DNFs implement cognitive operations. We illustrate how these mechanisms can be used to enable architectures of dynamic neural fields to perform cognitive functions such as acquiring and updating scene representations, using grounded spatial language, and generating sequences of actions. Implementing these DFT models in autonomous robots demonstrates how these cognitive functions can be enacted in embodied, situated systems.     

Social Value Orientation and information search in social dilemmas: An eye-tracking analysis

Previous work has demonstrated that Social Value Orientation (SVO) is related to cooperative behavior in social dilemmas. However, little is known concerning the underlying processes. In two eye-tracking studies investigating decisions in money allocation tasks (Experiment 1) and Public Good Dilemmas (Experiment 2), we show that differences in SVO are accompanied by consistent differences in information search. Decision time, number of fixations, the proportion of inspected information, the degree of attention towards the others’ payoffs, and the number of transitions from and towards others’ payoffs gradually increase with absolute SVO deviation from a pure selfish orientation. Overall these effects seem to be similar for individuals caring positively (i.e., cooperative) or negatively (i.e., competitive) about others. The fact that changes are gradual instead of abrupt indicates that differences in SVO seem to be related to gradual changes in weights given to outcomes for self and others.     

Serial recall and presentation schedule: A micro‐analysis of local distinctiveness

According to temporal distinctiveness theories, items that are temporally isolated from their neighbours during presentation are more distinct and thus are recalled better. Event‐based theories, which deny that elapsed time plays a role at encoding, explain isolation effects by assuming that temporal isolation provides extra time for rehearsal or consolidation of encoding. The two classes of theories can be differentiated by examining the symmetry of isolation effects: Event‐based accounts predict that performance should be affected only by pauses following item presentation (because they allow time for rehearsal or consolidation), whereas distinctiveness predicts that items should also benefit from preceding pauses. The first experiment manipulated inter‐item intervals and showed an effect of intervals following but not preceding presentation, in line with event‐based accounts. The second experiment showed that the effect of following interval was abolished by articulatory suppression. The data are consistent with event‐based theories but can be handled by time‐based distinctiveness models if they allow for additional encoding during inter‐item pauses.     

Relations between personality,knowledge, and behavior in professional service encounters

We report two studies that tested hypotheses about relations between personality, knowledge about service encounters, and performance in service encounters. A novel method for measuring knowledge was used. In one study, we measured undergraduates' personality, knowledge, and skill in handling service encounters in jobs performed by human factors professionals. The other study reanalyzed data reported by Motowidlo, Crook, Kell, and Naemi about volunteers' personality, knowledge about volunteer service encounters, and job performance. Both studies found that knowledge about service encounters is correlated with effectiveness in service encounters, even when effects of personality are controlled. Conscientiousness was correlated with this knowledge. We discuss implications of personality in the development of knowledge about effective behavior in social situations at work.     

Accuracy of respiratory symptom perception in persons with high and low negative affectivity

Accuracy of respiratory symptom perception was investigated in different contexts in participants (N = 56) scoring high or low for negative affectivity (NA). Within subject-correlations were calculated between minute ventilation (frequency per minute × tidal volume) and the subjective symptom ‘faster and/or deeper breathing’ across 10 subsequent breathing trials of 2?min with varying air mixtures, containing fresh or foul smelling odours and/or 5.5% CO₂. Half the participants were given a positive information frame for the sensations (‘some air mixtures may induce a pleasantly arousing feeling, like when being in love’), whereas the other half was given a negative frame (‘some air mixtures may induce feelings of being anxious and distressed’). Interoceptive accuracy was overall fairly high (r = 0.56–0.74), but it dropped considerably (r = 0.27), when bodily sensations were induced in high NA persons in a negative information frame (interaction, p < 0.005). Interoceptive accuracy appears low when persons with high NA are in situations characterised by negative affective cues.     

Who’s Afraid of Nagelian Reduction?

We reconsider the Nagelian theory of reduction and argue that, contrary to a widely held view, it is the right analysis of intertheoretic reduction. The alleged difficulties of the theory either vanish upon closer inspection or turn out to be substantive philosophical questions rather than knock-down arguments.     

Behandlungsleitlinie Persönlichkeitsstörungen

The S2 guidelines for the treatment of personality disorders (PD) are summarized. In the diagnostic assessment of personality disorders a clinical interview should be supplemented by (semi-) structured clinical interviews and self-report measures for the categorical and dimensional assessment of PDs. The results of the assessment process should be communicated to the patient based on a psycho-educational framework. The diagnosis should always be linked to the patient’s individual history. Psychotherapy is the treatment of choice for personality disorders. A detailed analysis of the patient’s problems as well as the definition of a hierarchy of treatment goals are part of the process of treatment planning. For three PDs empirical evidence for treatment approaches is available: (1) dialectical behavior therapy, mentalization-based therapy, schema focused therapy and transference focused therapy all proved beneficial in the treatment of borderline personality disorder. Cognitive-behavior therapy proved helpful in the treatment of (2) dissociative personality disorder and (3) avoidant personality disorder. There is limited evidence for interpersonal therapy and psychodynamic therapies in the treatment of avoidant personality disorder.
