Although the effect of aging on episodic memory is relatively well studied, little is known about how aging influences metamemory. In addition, while executive function (EF) is known to mediate the age-related decline in episodic memory, the role of metamemory in aging-related memory differences beyond EF remains unknown. This study aimed to elucidate the effect of aging on metamemory and to clarify the role of metamemory in the age-related decline in memory.

One hundred and four adults aged 18–79 years (50 M, 54 F) performed several EF tasks, as well as a face-scene paired-associate learning task that required them to make judgments of learning, feeling-of-knowing judgments, and retrospective confidence judgments.

Aging was significantly associated with poor metamemory accuracy and increased confidence across metamemory judgment types, even after controlling for EF and memory performance. A parallel mediation analysis indicated that both confidence of learning and EF performance had significant partial mediation effects on the relationship between aging and memory, albeit in different ways. Specifically, poor EF explained the age-related decline in memory, whereas increased confidence of learning served to compensate for this memory decline.

Aging is associated with general changes (i.e., poor inferences from cues) rather than specific changes (i.e., declined activation or utilization of certain cues) in metamemory monitoring. Also, changes in confidence of learning and in EF ability contribute to the preservation and decline of memory during aging, respectively. Therefore, boosting confidence during encoding and enhancing EF skills might be complementary memory intervention strategies for older adults.

Metamemory is a component of metacognition that includes both the knowledge of factors that affect memory (i.e., declarative metamemory) and knowledge and application of factors in one's own learning and recall performance (i.e., procedural metamemory; Kreutzer et al., 1975). Previous researchers have examined children's metamemory through interviews and found that metamemory abilities are positively associated with age and performance on memory measures (see Godfrey et al., 2022 for review). However, there is not yet a standardized measure to evaluate children's metamemory. The current study aimed to examine the psychometric characteristics of a declarative metamemory questionnaire, the Measure of Metamemory (MoM-10), for children ages 6-12 years old. Based on previous research, we hypothesized that performance on the MoM-10 would not be associated with sex but would be positively associated with age and learning and memory performance.

A total of 75 English-speaking typically developing children between the ages of 6 to 12 years old were recruited for the current study (M age=9.1+1.92; females 49%). Participants completed the MoM-10 which assessed declarative metamemory via 10 multiple choice questions (accuracy score of 0 or 1 points per question) and required participants to provide an explanation for their multiple-choice answer (explanation score of 0, 1, or 2 points per question). The metamemory questionnaire provided two outcome variables: an Accuracy score of 10 possible points, and an Explanation score of 20 possible points. Additionally, participants completed a 3-trial pictorial learning/memory task which provided an Immediate Recall score and Delayed Recall score.

As hypothesized, there were no sex differences on the MoM-10 Accuracy scores (t(73)=0.71, p=0.48) or Explanation scores (t(73)=-73, p=0.47). Consistent with our hypothesis, age was significantly associated with Accuracy (r=0.31, p<0.01) and Explanation scores (r=0.79, p<0.001). Internal consistency of the MOM-10 was moderate for the Explanation score (Cronbach's alpha=0.68) and low for the Accuracy score (KR-20=0.54). Lastly, after controlling for age, participants' MoM-10 Accuracy score was significantly associated with Immediate Recall (r=0.32, p<0.01) on the learning/memory task and the Explanation scores were significantly associated with the Immediate Recall (r=0.36, p<0.01) and Delayed Recall scores (r=0.32, p<0.01) on the learning/memory task.

The current study presents an initial review of psychometric properties of a metamemory questionnaire for children ages 6 to 12 years old. Additionally, as hypothesized, these results suggest the MOM-10 performance is significantly positively associated with participants' age and immediate and delayed recall performance on a pictorial learning/memory task. These associations provide lines of evidence for convergent validity given the expected maturation of metamemory with both age and with improvements in actual memory performance. However, based on the low internal consistency of the accuracy scores, further refinement will be explored including possibly rephrasing questions from the current item set or perhaps excluding current items in future use of the scale.

To create a standardized scoring procedure to evaluate open-ended responses as part of a novel questionnaire (Measure of Metamemory; MoM) designed to assess declarative metamemory in youth. Metamemory is an aspect of metacognition that is one’s knowledge of the factors related to storage and retrieval of information (Flavell 1971; Kreutzer et al., 1975), and includes both declarative metamemory (i.e., one’s knowledge about factors influencing memory) and procedural metamemory (i.e., one’s understanding of their own memory performance).

Fourteen short vignettes related to memory were administered to 100 participants (age 6-12) with questions such as, “Two children hear a story they must remember. The first person is 5 years old. The second person is 12 years old. Who is most likely to remember it best?” After answering, they were then prompted to explain their answer (i.e., “Why?”) and their responses were recorded verbatim. To develop standardized and objective criteria for each of the 14 open-ended responses, responses from a subsample of 20 youth were collectively examined by the study team and a scoring structure similar to open-ended items on common intelligence tests (e.g., WISC-V/WAIS-IV) was created. Two points (full credit) were awarded for complete and thorough understanding of memory processes related to the question; 1 point was given for partially accurate or incomplete understanding of the related memory process; and 0 points for an inability to correctly express an understanding of relevant memory concepts. This scoring guide was then applied independently by each of the six raters to an additional 25 participants (ages 6-12 mean age (SD)). To assess the interrater reliability of this 3-point ordinal scoring system, we examined both Fleiss’ kappa and 2-way random-effects, single-rater, absolute agreement Intra-Class Correlations (ICC).

Across the six independent raters, reliability coefficients for each of the 14 items ranged from (Fleiss') k =. 277 to .792 (ICC ranged from .481 to .880). Of these 14 items, the kappa value was classified (using interpretation rules for Cohen’s kappa) as “substantial” for 10 items, “moderate” for 3 items, and “fair” for 1 item. Based on these lower inter-rater reliabilities, two items were subsequently removed from the measure to create the 12-item open-ended measure of metamemory, the MoM-12, with reliable scoring for youth as young as 6 years old.

A consensus process established a quantifiable scoring procedure to assess open-ended responses related to youth’s knowledge of memory (e.g., metamemory). Reliability metrics identified acceptable interrater reliabilities in 12 of the 14 original items. Further examination of psychometric properties, including internal consistency and lines of evidence for validity is needed. The successful crafting of a scoring procedure is a first step towards developing a psychometrically sound measure (the MoM) to evaluate and study metamemory concepts objectively and reliably in youth.

Metamemory is an aspect of metacognition that is one's knowledge of memory and understanding of their own memory performance (Kreutzer et al., 1975). Executive function skills are foundational skills required for the development of metamemory in early school-age children (Lockl & Schneider, 2007; Lecce et al., 2015). Previous studies have suggested children with Attention-Deficit/Hyperactivity Disorder (ADHD) may have weaker study and organizational strategies, suggesting weaker metamemory skills (O'Neill & Douglas, 1991; Voelker et al., 1989). The current study aimed to examine the metamemory knowledge of typically developing (TD) children and children with ADHD on a novel declarative metamemory questionnaire. We hypothesized that the ADHD group would have worse metamemory performance than the TD group and that executive functioning skills would be significantly associated with metamemory for all groups.

The current study recruited a total of 93 English-speaking children between the ages of 6 to 12 years old, including 70 typically developing (TD) children (M age=9.1+1.92; females 49%), and 23 children with diagnoses of ADHD (M age=9.56+1.27; females 57%). Fifty-seven percent of the ADHD group reported daily use of stimulant medication, but no participants took medication on the day of testing. The participant groups did not significantly differ regarding age or sex. Participants completed the Measure of Metamemory (MoM-10) which included 10 multiple choice questions (i.e., Accuracy) and asked participants to explain their multiple-choice answer (i.e., Explanation). This provided three scores: Accuracy (max 10 points), Explanation (max 20 points), and Total (max 30 points). Additionally, participants' parents completed the 12-item Behavior Rating Inventory of Executive Function, 2nd Edition (BRIEF-2) Screening form, evaluating the child's executive functioning, which provided a percentile based on age and sex.

Within the ADHD group, BRIEF-2 percentiles and MoM-10 scores did not differ between those who were medicated and those who were not. As previous literature has shown, the TD and ADHD groups significantly differed on the BRIEF-2 screening score percentiles (t(91)=-5.78, p<0.001; TD M=52.89+26.1; ADHD M=85.26+13.82). The TD and ADHD groups did not significantly differ on either the MoM-10 Accuracy (p=0.13; TD M=7.22+1.84; ADHD M=7.87+1.32), the Explanation (p=0.08; TD M=9.34+3.80; ADHD M=10.57+2.92), or Total (p=0.13). There was a trend towards a significant correlation between the Explanation scores and BRIEF-2 for TD participants (r=-0.23, p=0.06), but there was no significant correlation between Explanation, Accuracy, or Total scores and the BRIEF-2 for the ADHD group.

Our results tentatively suggest a possible association between metamemory and parent reported executive functioning for TD children, supporting the expected association between the development of executive functioning and the development of metamemory. However, there was no association between metamemory and executive functioning for children with ADHD, likely due to the restricted range of executive functioning scores for this group (i.e., M=85.25+13.82; Range 55-99). Additionally, metamemory did not significantly differ between diagnostic groups. Children with ADHD may have comparable metamemory knowledge to TD children as a result of executive functioning instruction and support they have received. Rather, there may be group differences in the application of metamemory judgement and strategies.

While loss of insight into one’s cognitive impairment (anosognosia) is a feature in Alzheimer’s disease dementia, less is known about memory self-awareness in cognitively unimpaired (CU) older adults or mild cognitive impairment (MCI) or factors that may impact self-awareness. Locus of control, specifically external locus of control, has been linked to worse cognitive/health outcomes, though little work has examined locus of control as it relates to self-awareness of memory functioning or across cognitive impairment status. Therefore, we examined associations between locus of control and memory self-awareness and whether MCI status impacted these associations.

Participants from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study (mean age=73.51; 76% women; 26% Black/African American) were classified as CU (n=2177) or MCI (amnestic n=313; non-amnestic n=170) using Neuropsychological Criteria. A memory composite score measured objective memory performance and the Memory Functioning Questionnaire measured subjective memory. Memory self-awareness was defined as objective memory minus subjective memory, with positive values indicating overreporting of memory difficulties relative to actual performance (hypernosognosia) and negative values indicating underreporting (hyponosognosia). Internal (i.e., personal skills/attributes dictate life events) and external (i.e., environment/others dictate life events) locus of control scores came from the Personality in Intellectual Aging Contexts Inventory. General linear models, adjusting for age, education, sex/gender, depressive symptoms, general health, and vocabulary examined the effects of internal and external locus of control on memory self-awareness and whether MCI status moderated these associations.

Amnestic and non-amnestic MCI participants reported lower internal and higher external locus of control than CU participants. There was a main effect of MCI status on memory self-awareness such that amnestic MCI participants showed the greatest degree of hyponosognosia/underreporting, followed by non-amnestic MCI, and CU participants slightly overreported their memory difficulties. While, on average, participants were fairly accurate at reporting their degree of memory difficulty, internal locus of control was negatively associated with self-awareness such that higher internal locus of control was associated with greater underreporting (ß=-.127, 95% CI [-.164, -.089], p<.001). MCI status did not moderate this association. External locus of control was positively associated with self-awareness such that higher external locus of control was associated with greater hypernosonosia/overreporting (ß=.259, 95% CI [.218, .300], p<.001). Relative to CU, amnestic, but not non-amnestic, MCI showed a stronger association between external locus of control and memory self-awareness. Specifically, higher external locus of control was associated with less underreporting of cognitive difficulties in amnestic MCI (ß=.107, 95% CI [.006, .208], p=.038).

In CU participants, higher external locus of control was associated with greater hypernosognosia/overreporting. In amnestic MCI, the lower external locus of control associations with greater underreporting of objective cognitive difficulties suggests that perhaps reduced insight in some people with MCI may result in not realizing the need for external supports, and therefore not asking for help from others. Alternatively, in amnestic participants with greater external locus of control, perhaps the environmental cues/feedback translate to greater accuracy in their memory self-perceptions. Longitudinal analyses are needed to determine how memory self-awareness is related to future cognitive declines.

In normative aging, there is a decline in associative memory that appears to relate to self-reported everyday use of general memory strategies (Guerrero et al., 2021). Self-reported general strategy use is also strongly associated with self-reported memory abilities (Frankenmolen et al., 2017), which, in turn, are weakly associated with objective memory performance (Crumley et al., 2014). Associative memory abilities and strategy use appear to differ by gender, with women outperforming men and using more memory strategies (Hertzog et al., 2019). In this study, we examine how actual performance and self-reported use of specific strategies on an associative memory task relate to each other and to general, everyday strategy use, and whether these differ by gender.

An international sample of older adults (N = 566, 53% female, aged 60-80) were administered a demographic questionnaire and online tasks, including 1. the Multifactorial Memory Questionnaire (MMQ) which measures self-reported memory ability, satisfaction, and everyday strategy use (Troyer & Rich, 2018); and 2. the Face-Name Task which measures associative memory (Troyer et al., 2011). Participants were also asked about specific strategies that were used to complete the Face-Name Task.

On the Face-Name Task, participants who reported using more strategies performed better (F(3, 562) = 6.51, p < 0.001, n2 = 0.03), with those who reported using three or four strategies performing best (p < .05). There was a significant difference in performance based on the type of strategy used (p(2, 563) = 11.36, p < 0.001, n2 = 0.04), with individuals who relied on a “past experiences/knowledge” strategy performing best (p < .01). Women (M = 0.79, SD = 0.19) outperformed men (M = 0.71, SD = 0.20), f(545) = -4.64, p < 0.001, d = -0.39. No gender differences were found in the number (X2(3, N = 564) = 2.06, p = 0.561) or type (x2(2, N = 564) = 5.49, p = 0.064) of strategies used on the Face-Name Task. Only participants who reported using no strategies on the Face-Name Task had lower scores on the MMQ everyday strategy use subscale (p < .05). A multiple-regression model was used to investigate the relative contributions of the number of strategies used on the Face-Name Task, MMQ everyday strategy subscale score, gender, age, education, and psychological distress to Face-Name Task performance. The only significant predictors in the model were gender (B = 0.08, t(555) = 4.55, p < 0.001) and use of two or more strategies (B = 0.07, f(555) = 2.82, p = 0.005).

Reports of greater self-initiated strategy use, and use of a semantic strategy in particular, related to better performance on an associative memory test in older adults. Self-initiated, task-specific strategy use also related to everyday strategy use. The findings extend past work on gender differences to show that women outperform men on an associative memory task but that this is unlikely to be due to self-reported differences in strategy use. The results suggest that self-reported strategy use predicts actual associative memory performance and should be considered in clinical practice.

In neurological diseases, metacognitive judgements have been widely used in order to assess the degree of disease awareness. However, as yet little research of this type has focused on multiple sclerosis (MS).

We here focused on an investigation of item-by-item metacognitive predictions (using feeling-of-knowing judgements) in episodic and semantic memory and global metacognitive predictions in standard neuropsychological tests pertinent to MS (processing speed and verbal fluency). Twenty-seven relapsing–remitting MS (RR-MS) patients and 27 comparison participants took part.

We found that RR-MS patients were as accurate as the group of comparison participants on our episodic and semantic item-by-item judgements. However, for the global predictions, we found that the MS group initially overestimated their performance (ds = .64), but only on a task on which performance was also impaired (ds = .89; processing speed). We suggest that MS patients, under certain conditions, show inaccurate metacognitive knowledge. However, postdictions and item-by-item predictions indicate that online metacognitive processes are no different from participants without MS.

We conclude that there is no monitoring deficit in RR-MS and as such these patients should benefit from adaptive strategies and symptom education.

In previous studies we suggested that liberal acceptance (LA) represents a fundamental cognitive bias in schizophrenia and may explain why patients are more willing to accept weak response alternatives and display overconfidence in incorrect responses. The aim of the present study was to test a central assumption of the LA account: false alarms in schizophrenia should be particularly increased when the distractor–target resemblance is weak relative to a control group.

Sixty-eight schizophrenia patients were compared to 25 healthy controls on a visual memory task. At encoding, participants studied eight complex displays, each consisting of a unique pairing of four stimulus attributes: symbol, shape, position and colour. At recognition, studied items were presented along with distractors that resembled the targets to varying degrees (i.e. the match between distractors and targets ranged from one to three attributes). Participants were required to make old/new judgements graded for confidence.

The hypotheses were confirmed: false recognition was increased for patients compared to controls for weakly and moderately related distractors only, whereas strong lure items induced similar levels of false recognition for both groups. In accordance with prior research, patients displayed a significantly reduced confidence gap and enhanced knowledge corruption compared to controls. Finally, higher neuroleptic dosage was related to a decreased number of high-confident ratings.

These data assert that LA is a core mechanism contributing to both enhanced acceptance of weakly supported response alternatives and metamemory deficits, and this may be linked to the emergence of positive symptomatology.
