Letter familiarity does not aid feature extraction

Summary Familiarity effects in visual letter processing were examined by means of a mutilation detection task. The uppercase E was used as the non-mutilated letter. One or two horizontal bars of the E were delected, to produce an upright or inverted F or L. These four mutilations of the E were assigned to the same response. In Experiment 1, brief exposure of the stimuli was followed by a backward mask. Experiment 2 was identical to Experiment 1, except that the display duration of the stimulus was increased and the backward mask was omitted. In Experiment 3, the overall luminance of the stimuli (luminance per point times length of the constituent line segments) was held constant. In Experiment 4, the upright and inverted non-E letter occurred in different blocks to encourage a normal (upright) letter processing strategy in the upright letter blocks. Accuracy (Experiment 1) and mean correct response times (all experiments) were not different for the upright and inverted F or for the upright and inverted L. These findings and converging results from other studies indicate that the higher familiarity of the upright letters did not aid feature extraction.     

Die Abschaffung der somatoformen Störungen durch DSM-5 – ein akademischer Schildbürgerstreich?

The new fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has introduced “somatic symptom disorder” as a diagnosis which is no longer differentiated into medically unexplained and explained physical symptoms. As a consequence, the status of somatoform disorders as an independent clinical group is called into question. Against all original intentions, the semantic, conceptual and practical problems of the previous classification have not been solved. The validity of the new diagnosis is doubtful because of its over-inclusive character. Further points of criticism are the less than optimal selection of psychological features, the abandonment of hypochondriasis as a homogeneous concept and imprecise workmanship of the diagnostic criteria where exclusion criteria needed for differential diagnosis are missing.     

Music as a way of knowing: tentative steps towards extending the boundaries of traditional music philosophy

Based on Howard Gardner's theory of Multiple Intelligences and Ray Jackendoff s theory of a Universal Musical Grammar this article proposes that music be regarded as a way of knowing by which man endeavours to make sense of, interpret and articulate—by means of a system of sound symbols—an aspect of reality which cannot be expressed in any other way. The four main points of this hypothesis are: (1) Music refers to a reality that is neither solely a product of my imagination, my feelings or the constitution of my body, nor to a reality that can be explained solely in empirical terms. Rather, it includes both these dimensions, but at the same time is more than both of them put together. (2) The language of music is unique in that it is structured like no other language; it is structured in accordance with the reality it refers to. (3) Unlike mathematics (or even spoken language), the language of music, in its manifestation as culturally diverse musics, is semantically and ethically not a neutral language. (4) The emergence of art music can be explained particularly well by means of the model of music as a way of knowing.     

When we like what we know – A parametric fMRI analysis of beauty and familiarity

This paper presents a neuroscientific study of aesthetic judgments on written texts. In an fMRI experiment participants read a number of proverbs without explicitly evaluating them. In a post-scan rating they rated each item for familiarity and beauty. These individual ratings were correlated with the functional data to investigate the neural correlates of implicit aesthetic judgments. We identified clusters in which BOLD activity was correlated with individual post-scan beauty ratings. This indicates that some spontaneous aesthetic evaluation takes place during reading, even if not required by the task. Positive correlations were found in the ventral striatum and in medial prefrontal cortex, likely reflecting the rewarding nature of sentences that are aesthetically pleasing. On the contrary, negative correlations were observed in the classic left frontotemporal reading network. Midline structures and bilateral temporo-parietal regions correlated positively with familiarity, suggesting a shift from the task-network towards the default network with increasing familiarity.     

Aesthetic appreciation of poetry correlates with ease of processing in event-related potentials

Rhetorical theory suggests that rhythmic and metrical features of language substantially contribute to persuading, moving, and pleasing an audience. A potential explanation of these effects is offered by “cognitive fluency theory,” which stipulates that recurring patterns (e.g., meter) enhance perceptual fluency and can lead to greater aesthetic appreciation. In this article, we explore these two assertions by investigating the effects of meter and rhyme in the reception of poetry by means of event-related brain potentials (ERPs). Participants listened to four versions of lyrical stanzas that varied in terms of meter and rhyme, and rated the stanzas for rhythmicity and aesthetic liking. The behavioral and ERP results were in accord with enhanced liking and rhythmicity ratings for metered and rhyming stanzas. The metered and rhyming stanzas elicited smaller N400/P600 ERP responses than their nonmetered, nonrhyming, or nonmetered and nonrhyming counterparts. In addition, the N400 and P600 effects for the lyrical stanzas correlated with aesthetic liking effects (metered–nonmetered), implying that modulation of the N400 and P600 has a direct bearing on the aesthetic appreciation of lyrical stanzas. We suggest that these effects are indicative of perceptual-fluency-enhanced aesthetic liking, as postulated by cognitive fluency theory.     

Kognitive Therapie des chronischen dekompensierten Tinnitus

Chronic earnoises lead to severe emotional disturbances in many individuals. At the moment, it is not possible to treat chronic tinnitus effectively on a medical basis. If the individual suffers strongly, psychological interventions can help reduce the degree of subjective tinnitus annoyance. Psychotherapists are often insecure when treating tinnitus sufferers, because of their tendency to strongly focus on the chronic earnoises. Knowledge about typical dysfunctional beliefs and systematic cognitive mistakes, that hinder the habituation process in tinnitus sufferers, help understand the patient and help find an anchor point for reducing tinnitus annoyance. In this paper, the most important cognitive characteristics of tinnitus sufferers are summarised and the cognitive modification process is systematically described.     

Die Geisteswissenschaften und die Praxis

Ohne ZusammenfassungDer vorliegende Beitrag stellt die auf das Dreifache erweiterte Fassung eines Vortrags dar, den ich unter dem Titel Zur Funktion der Geisteswissenschaften in der Konzeption von J.

Hypochondriasis Among Patients with Multiple Somatoform Symptoms—Psychopathology and Outcome of a Cognitive-Behavioral Therapy

As hypochondriasis often occurs with somatization, patients with somatization disorder plus hypochondriasis were compared to patients with somatization syndrome alone regarding psychopathology, patterns of physical symptoms and outcome of a cognitive-behavioral inpatient treatment. A sample of patients with DSM-IV hypochondriasis and multiple somatoform symptoms(N = 27) and a matched sample of patients with multiple somatoform symptoms but without hypochondriasis (N = 27) were assessed. All subjects obtained a cognitive-behavioral treatment for somatization and hypochondriasis. Assessment took place at admission and at one-year follow-up. Only a few differences between the groups were found: Hypochondriacs suffered more often from abdominal pain, and they reported a higher intolerance of bodily complaints. At follow-up, all outcome variables improved significantly. High effect sizes were found for the reduction of symptoms and the mean number of visits to the doctor. The specific effect on health care use highlights the socioeconomic relevance of these results.     

Overgeneral memory and suppression of trauma memories in post-traumatic stress disorder

The study investigated the relationship between the suppression of trauma memories and overgeneral memory in 42 assault survivors with and without PTSD. Overgeneral memory (OGM) was assessed with a standard autobiographical memory test (AMT). Participants completed two further AMTs under the instructions to either suppress or not suppress assault memories, in counterbalanced order. Participants with PTSD retrieved fewer and more general memories when following the suppression instruction than participants without PTSD, but not under the control instruction. OGM correlated with PTSD symptom severity, and measures of cognitive avoidance. The results are discussed with reference to current theories of overgeneral memory and its possible relationship with PTSD.
