On the pervasive effect of word frequency in metamemory

The Self-Reference Effect in Metamemory and the Role of Beliefs in This Process

Previous research has shown a clear self-reference effect in our memory. However, the question arises as to whether this effect could extend to higher cognitive domains such as metamemory. Thus, this study examined the effects of different encoding types on judgments of learning (JOLs) and explored the role of beliefs in this process. A one-way (encoding type: semantic, self-referential) within-participants design was employed in Experiment 1, which found no self-reference effect in JOLs. In Experiment 2, we manipulated participants' beliefs to explore their effect on JOLs under different encoding strategies. The results showed that learners' metamemory beliefs about encoding types influence JOLs. Learners who believed that self-referential and semantic encoding had the same memory effect tended to give equal JOLs to both words. However, learners who believed that self-referential encoding had a better memory effect than semantic encoding gave higher JOLs to self-referentially encoded words. The conclusions are as follows: There is no self-reference effect in JOLs, but learners' metamemory beliefs about encoding types influence JOLs.

Metacognitive processes accompanying the first stages of autobiographical retrieval in the self-memory system

According to Conway's view, Autobiographical memory (AM) construction is accompanied by control processes. These processes range from filtering out relevant memories according to the current context, to generating or elaborating appropriate retrieval cues. These processes can be conceptualised as metacognition, the ability to control and monitor cognitive processes. Experimentally, little has been carried out to support the idea that metacognition is involved in AM. To assess this, we designed a task, the Feeling of Retrieval. Participants had to predict whether cue words would facilitate AM access (i.e., fluent access cues) or not (i.e., limited access cues) in a limited time (either 1 (Exp. 2) or 2 (Exp. 1) s). Later, they retrieved memories in response to both types of cues. Results show that cues judged as fluent access led to better AM generation, as illustrated by AM retrieval latency and a subjective measure of the ease with which the AMs were retrieved. These rapid predictions may rely on epistemic feelings and / or other mnemonic cues such as a partial retrieval of information. This metacognitive access to the earliest stages of AM retrieval illustrates the ability to monitor AM processes as proposed by Conway (2005).

Cooking through perceptual disfluencies: The effects of auditory and visual distortions on predicted and actual memory performance

The current study investigated the joint contribution of visual and auditory disfluencies, or distortions, to actual and predicted memory performance with naturalistic, multi-modal materials through three experiments. In Experiments 1 and 2, participants watched food recipe clips containing visual and auditory information that were either fully intact or else distorted in one or both of the two modalities. They were asked to remember these for a later memory test and made memory predictions after each clip. Participants produced lower memory predictions for distorted auditory and visual information than intact ones. However, these perceptual distortions revealed no actual memory differences across encoding conditions, expanding the metacognitive illusion of perceptual disfluency for static, single-word materials to naturalistic, dynamic, multi-modal materials. Experiment 3 provided naïve participants with a hypothetical scenario about the experimental paradigm used in Experiment 1, revealing lower memory predictions for distorted than intact information in both modalities. Theoretically, these results imply that both in-the-moment experiences and a priori beliefs may contribute to the perceptual disfluency illusion. From an applied perspective, the study suggests that when audio-visual distortions occur, individuals might use this information to predict their memory performance, even when it does not factor into actual memory performance.
