Negative affect interference and fear of happiness are independently associated with depressive symptoms.

OBJECTIVES: Reward devaluation theory (RDT) posits that some depressed individuals avoid positivity due to its previous association with negative outcomes. Behavioral indicators of avoidance of reward support RDT, but self-report indicators have yet to be examined discriminantly. Two candidate self-report measures were examined in relation to depression: negative affect interference (NAI), or the experience of negative affect in response to positivity, and fear of happiness, a fear of prospective happiness. METHOD: Participants completed measures assessing NAI, fear of happiness scale, and depression online via Amazon's Mechanical Turk at three time points (N = 375). Multilevel modeling examined the relationship between NAI, fear of happiness, and depressive symptoms longitudinally. RESULTS: NAI and fear of happiness were both positively associated with depressive symptoms. They both uniquely predicted depressive symptoms when included within the same model. CONCLUSIONS: These findings suggest that different conceptualizations of positivity avoidance are uniquely associated with depressive symptoms.

Both congruent and incongruent trials drive the congruency sequence effect: Novel support for an episodic retrieval view of adaptive control in the prime-probe task.

The congruency effect in Stroop-like tasks-a popular measure of distraction-is smaller after incongruent relative to congruent trials. However, it is unclear whether this congruency sequence effect (CSE)-a popular index of coping with distraction-reflects adjustments of control after congruent trials, incongruent trials, or both. The episodic retrieval account of the CSE posits adjustments of control after both congruent and incongruent trials. In this account, retrieving a memory of the previous trial's congruency (i.e., congruent or incongruent) biases control processes to prepare for an upcoming trial with the same congruency (i.e., congruent or incongruent). In contrast, the default setting account posits adjustments of control after a single trial type. For example, control processes might increase inhibition of the response cued by the distractor after incongruent trials but make no adjustments after congruent trials. To distinguish between these accounts for the first time while (a) using long distractor-target intervals and (b) excluding prevalent feature integration and contingency learning confounds, we employed a confound-minimized prime-probe task with neutral trials. We usually observed adjustments of control after both trial types. Furthermore, whether the reduction of the congruency effect after incongruent trials indexed (a) inhibition of the distractor-congruent response or (b) activation of the distractor-incongruent response depended on whether the distractor and target were same-sized or different-sized, respectively. These findings favor the episodic retrieval account of the CSE over the default setting account. They also indicate that "low-level" stimulus properties may influence the nature of "high-level" control adjustments. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
