Are feeling-of-knowing and judgment-of-learning different? Evidence from older adults

International audienceThis study aims to assess age differences between Judgments-of-learning (JOLs) and Feeling-of-knowing (FOKs) as they are typically studied. The novel contribution of the present study is a comparison between these two metacognitive judgments in a within subject design. Young and older adults were tested on their JOL accuracy and were asked to predict future recall during learning. All participants were also asked to predict future recognition of unrecalled items (FOK judgments). Results showed that although older adults had similar low levels of memory performance in the JOL task and in the FOK task, metacognitive impairments were only found on the resolution of FOKs. Furthermore, an analysis of covariance showed that age differences on memory performance explained the age effect observed on the FOK, thus supporting the memory constraint hypothesis (Hertzog et al., 2010). Results are discussed in relation to contemporary models of memory
