Background: Recent studies indicate that depressed individuals may have difficulties disengaging visual-spatial attention from negative information. Preliminary studies in depressed older adults provide evidence for the existence of biased attention to negative stimuli. However, the specific components of attention driving the detected bias effects in this population are not known. Aims: This study examined the mechanisms underlying attention biases in Late Life Depression (LLD). It was predicted that depressed older adults, like their younger counterparts, would demonstrate an impaired ability to disengage attention from negative stimuli relative to neutral and positive stimuli, as compared to non-depressed older adult controls. Methods: 16 clinically depressed older adults and 22 older adult controls matched for age, gender and pre-morbid verbal IQ performed an emotional spatial cueing task that required classifying a target stimulus. The location of the target was correctly or incorrectly cued by a neutral, positive or negative word. Results: Planned comparisons did not support the primary hypotheses. However, participants in the depressed group, in general, were slower to respond than participants in the control group. Conclusions: Results suggest that the ability to disengage attention from negative words is not impaired in LLD; however methodological limitations prevent firm conclusions being drawn. Possible explanations for the results are discussed along with directions for future research.
