| Popis: | Clinical depression with verbal short-term memory relation research does not yield unequivocal results. While short-term memory (STM) deficits in depressed patients are consistently displayed in working memory (WM) and executive attention tasks, for STM passive memorizing tasks this holds less correct. Objective. Primary goal was to collect initial data on depressed patients treated in Serbian institutions WM/ STM. In addition, we estimated the power of WAIS IV WM subtests to discriminate depressed patients from normal subjects. Method. Depressed patients' sample was contrasted with the parallel group in WAIS' IV Arithmetic, Digit Span, and Letter- Number Sequencing; free word recall task, semantic fluency task, without and with category switching. Results. All the WM measures, with the exception of Digit Span Backward score, discriminate depressed from no depressed subjects. On the other hand, STM tasks, with the exception of short-term word free recall, fail to do the same. We suggest explanation for both the exceptions in terms of WM efficiency. WAIS IV Arithmetic, Digit Span Sequencing and Letter-Number Sequencing can be used to discriminate depressed from control subjects. Performance in STM/WM tasks is in moderate to strong negative correlation with depression severity as assessed with the Hamilton scale. Conclusion. STM deficits in the depressed are likely to be observed in tasks requiring executive attention and WM efficiency rather than in standard STM span tasks. The deficits are inertly related to depression severity. |
