Dichotic listening with forced attention in patients with temporal lobe epilepsy: significance of left hemisphere cognitive dysfunction

Fifty right-handed patients with focal temporal lobe epilepsy were administered a dichotic listening test with consonant-vowel syllables under non-forced, forced right and forced left attention conditions, and a neuropsychological test battery. Dichotic listening performance was compared in subgroups with and without left hemisphere cognitive dysfunction, measured by the test battery, and in subgroups with left and right temporal epileptic focus. Left hemisphere cognitive dysfunction led to more correct responses to left ear stimuli in all three attention conditions, and fewer correct responses to right ear stimuli in the non-forced attention condition. This was probably caused by basic left hemisphere perceptual dysfunction. Dichotic listening was less affected by a left-sided epileptic focus than by left hemisphere cognitive dysfunction. General cognitive functioning influenced dichotic listening performance stronger in forced than in non-forced attention conditions. Larger cerebral networks were probably involved in the forced attention conditions due to the emphasis on conscious effort.     

Decreased approach motivation in depression

The present study examined relations between choice preference and reaction time to emotionally valenced words, dysphoric symptoms (BDI), and dysfunctional attitudes (DAS) in clinically depressed (CD; n= 61), previously depressed (PD; n= 42), and never depressed controls (ND; n= 46). The results showed: (1) NDs and PDs exhibited a choice preference for the relatively more positive words and differed significantly from CDs; (2) PDs and CDs exhibited longer reaction time and differed significantly from NDs; and (3) BDI and DAS were positively associated with reaction time to positively valenced words, whereas no associations were found for reaction time to negatively valenced words. The increased reaction time, in PDs and CDs, is discussed as a possible vulnerability factor to depression, which may be related to decreased approach motivation.     

The inquiring mind

There is nothing, either in the recent developments of philosophy or in the development of the sciences, which should prevent philosophy from continuing its role of mother‐science and the sciences from influencing methods and conclusions of philosophers. The inquiring mind respects no boundaries between disciplines except those which are imposed by differences in questions raised. But basic questions, whether raised by philosophers or by scientists, tend to have components requiring co‐ordination of research or analysis of highly different disciplines. Both Anglo‐Saxon and continental developments in philosophy justify, however, a distinction between cultivating philosophy and being engaged in solving or resolving a philosophical problem, the former comprising the latter.     

Using facial emotional stimuli in visual search experiments: The arousal factor explains contradictory results

For more than two decades, visual search experiments using pictures of emotional faces as stimuli have generated contradictory results. Evidence of a superior detection of angry faces compared to happy faces have been mixed with an equal amount of evidence in the opposite direction. In this article, we review this literature, and examine the hypothesis that the neglected stimulus factor of emotional arousal may explain these contradictory results. Through an extensive reanalysis of results from our own laboratory as well as from other researchers, we show that the arousal factor systematically influences the outcome of the reviewed visual search experiments, and may thus provide a key to the historical contradictions within this research field.     

Potential Space - The Place of Encounter between Inner and Outer Reality

This paper was one in a series of lectures called ''Space and identity'' that were given to a public audience during the spring of 1998. ''Space and identity'' was part of the program for Stockholm as the cultural capital of Europe in 1998 and was arranged by the Museum of Architecture and the two psychoanalytical societies in Stockholm. Building on the theories of especially Winnicott and Bion and with references to literature the paper gives a picture of the development of inner space and of potential space as the place for creativity and creative living.     

A Comment on teurnell's “the piggle—a sexually abused girl?”

Abstract

In his comment on Teurnell's paper “The Piggle—a sexually abused girl?” the author points to the risk of organizing a complicated clinical material around one single idea and briefly describes other ways of understanding the material in Winnicott's book. To the author's mind, the richness and depth of the material and the subtleness and aesthetics of the interplay between Winnicott and the Piggle, in Teurnell's way of reading, collapse into one single question: the possibility of a sexual trauma. At the end of the comment the role of the Piggle's father is shortly discussed.
