Emotional stroop performance in older adults: effects of habitual worry.

OBJECTIVE: In clinically anxious individuals, selective attention to negative cues in the environment may perpetuate a vicious cycle of emotional dysfunction. However, very little is known regarding the role of negative attentional bias in anxious older adults. There is evidence that in older adults without clinical anxiety, the opposite bias (toward positive, and away from negative, emotional material) is present. We explored how these age-related changes in emotional processing interact with anxiety.
METHOD: Sixty older adults (age 60+) completed the emotional Stroop (eStroop) task, a widely used measure of attentional bias, which requires rapid identification of the color in which neutral and emotional words are printed. Participants were stratified into high-, mid-, and low-worry groups on the basis of a self-report measure, the Penn State Worry Questionnaire.
RESULTS: The high-worry group exhibited a bias toward threat-related words whereas the low- and mid-worry groups showed a bias away from threat-related words. By contrast, the low- and mid-worry groups showed a bias toward positive words, potentially consistent with an established positivity effect in older adults whereas the high-worry group showed a bias away from positive items.
CONCLUSION: Older adults who worry frequently exhibit a pattern of eStroop performance that is broadly consistent with the younger adult literature, suggesting that selective attention toward threat-related information may be seen as a relevant factor in older, as in younger, anxiety.
