- W2897881029 abstract "Metacognition is defined as the knowledge and reflective capacities one has concerning one's own cognitive functioning.In recent years, metacognition studies have also advanced to older adults and the efforts are based on the idea that self-reflection can serve as a “bridge between decision making and memory, between learning and motivation, between learning and cognitive development”.Recent studies suggest that unawareness of memory impairment reflects not only damage to self-referential networks but also to memory and to the connections between these networks.This evidence hints a bidirectional relationship between self-reflection about memory and memory performance.The authors aim to verify if lack of metacognition predicts worst cognitive performance in a population-based study. The data derived from a study previously published underwent a post-hoc analysis. In this referred study,a metacognitive questionnaire(Memory Assessment Clinic-Q,MAC-Q) and a brief cognitive assessment[semantic verbal fluency test of animals(SVFTa) and fruits(SVFTf), and Montreal cognitive assessment(MoCA)] were applied in a volunteer sample of community-dwelling middle-aged and older adults(above 40y), with high educational level (12y or more).Participants were divided into four groups:Normal Group(NG), Subjective Memory Complaints(SMC), Lack of Metacognition(LM) and Objective Cognitive Impairment(OCI).The groups LM(n=24) and OCI(n=18), selected due to lowest cognitive scores, were the only ones below cutoff.The LM group has altered cognitive tests without memory complaints, showing memory unawareness and the OCI group has memory complaints with altered cognitive tests, denoting self-awareness about its memory.The analysis was adjusted for age, since it was the only significant variable of distinction between the groups(among others, such as gender, schooling and marital status).These two groups were compared(Mann-Whitney test) for outcomes in the brief cognitive battery. Significant differences in cognitive performance were not found.In the middle-aged (40–64y) subgroup, the scores between LM vs. OCI were:SVFTf(median/standard deviation,12±2,8 vs. 15±4;p=0,573),SVFTa (15,5±6,4 vs. 20±11,7;p=0,811) and MoCA(23,5±2,8 vs. 25±2;p=0,469).Significance was also not found in the elderly (above 64y) subgroup:SVFTf(12,5±4,8 vs. 12±3,3;p=0,591),SVFTa (15,5±5,3 vs. 16±4,7;p=0,533) and MoCA(21±3,8 vs. 21±4,8;p=0,747). Lack of metacognition does not predict worst cognitive performance,in a community-dwelling middle-aged and elderly population with high educational level, although in the middle-aged subgroup, there is a consistent tendency to lower scores." @default.
