Low perceived control as a risk factor for episodic memory: the mediational role of anxiety and task interference.

Low perceived control is considered a risk factor for poor cognitive functioning, but the mechanisms are unclear. The goal of the present study was to analyze anxiety and task interference as sequential mediators of the association between control beliefs and episodic memory. Cognitive-specific control beliefs were assessed prior to the lab session. State anxiety was assessed in the lab, followed by a word list recall task. The frequency of intrusive thoughts during the memory task was reported by the participants as a measure of task interference after the completion of the cognitive testing. The results for 152 participants from the ages of 22 to 84 years supported the predicted three-path mediation model. Lower levels of control beliefs were associated with higher state anxiety, which in turn affected episodic memory performance by increasing the likelihood of task interference, with age, sex, and verbal abilities as covariates. The implications of the results for developing interventions to improve memory performance are considered.
