Effects of memory self-efficacy beliefs on brain activity

Memory self-efficacy beliefs do not necessarily reflect objective memory performance. Nonetheless, those beliefs may modulate the way a cognitive task is apprehended. We hypothesized that such modulation might be revealed at the brain-activity level when performing a task. Younger and older adults completed the prospective and retrospective metamemory questionnaire before undergoing functional Magnetic Resonance Imaging. In the scanner, participants imagined themselves in scenes requiring motor processes (e.g., planting flowers) or not (e.g., waiting for the bus), and memorized them. After scanning, participants recalled scenes and rated their vividness. Only in the motor condition, low-memory believers elicited more brain activity than high-memory believers, independent of age (p < .001). Additionally, higher activity in frontal cortex and precuneus was related to poorer vividness in the younger group (p = .02). These patterns may reflect increased effortful operations during mental imagery among persons with low memory beliefs.
