Attention bias towards personally relevant stimuli: the individual emotional Stroop task.

The emotional Stroop task is a widely used method for investigating attentional bias towards stimuli due to mood or affect. In general, standardized stimuli are used, which might not be appropriate when investigating individual contextual frameworks. It was investigated whether words chosen to be related to individuals' personal life events would produce more pronounced Stroop interference (as an indicator of attentional bias) than stimuli without any personal relevance.

Cognitive performance and subjective complaints before and after remission of major depression.

Introduction: Patients with major depression report on severe cognitive deficits but objective neuropsychological test results indicate rather mild problems. In the present study we aimed at investigating neuropsychological performance, subjective complaints, and observer ratings of cognitive abilities in everyday life.

Methods: Fifteen patients with major depression were studied in the acute state of illness and after remission.

Comparison between visual half-field performance and cerebral blood flow changes as indicators of language dominance.

The determination of hemispheric language dominance (HLD) can be accomplished in two ways. One approach relies on hemispheric differences in cerebral blood flow velocity (CBFV) changes during language activity, while the other approach makes use of performance differences between the left and right visual field when verbal stimuli are presented in a tachistoscopic visual field paradigm. Since both methodologically different approaches claim to assess functional HLD, it seems plausible to expect that the respective laterality indices (LI) would correspond.

Comparison of hemispheric activation during mental word and rhyme generation using transcranial Doppler sonography.

The Wada test is at present the method of choice for preoperative assessment of patients who require surgery close to cortical language areas. It is, however, an invasive test with an attached morbidity risk. By now, an alternative to the Wada test is to combine a lexical word generation paradigm with non-invasive imaging techniques.

A new approach in clinical neuropsychology to the assessment of spatial working memory: the block suppression test.

The Block Suppression Paradigm developed by Beblo, Klaver, Grubich, Wachowius, and Herrmann (1999) is based on the Corsi Block tapping test and requires that a subject reproduces every 2nd block in a given sequence. Results from two studies of a standardized version, the Block Suppression Test (BST), are presented here. In Study 1 the BST was administered to 48 healthy subjects along with a battery of comprehensive neuropsychological tests.
