Metacognitive reflection and insight therapy (MERIT) for patients with schizophrenia
2019
Impaired metacognition is associated with difficulties in the daily functioning of people with psychosis. Metacognition can be divided into four domains: Self-Reflection, Understanding the Other's Mind, Decentration, and Mastery. This study investigated whether Metacognitive Reflection and Insight Therapy (MERIT) can be used to improve metacognition.
This study is a randomized controlled trial. Patients in the active condition (n = 35) received forty MERIT sessions, the control group (n = 35) received treatment as usual. Multilevel intention-to-treat and completers analyses were performed for metacognition and secondary outcomes (psychotic symptomatology, cognitive insight, Theory of Mind, empathy, depression, self-stigma, quality of life, social functioning, and work readiness).
Eighteen out of 35 participants finished treatment, half the drop-out stemmed from therapist attrition (N = 5) or before the first session (N = 4). Intention-to-treat analysis demonstrated that in both groups metacognition improved between pre- and post-measurements, with no significant differences between the groups. Patients who received MERIT continued to improve, while the control group returned to baseline, leading to significant differences at follow-up. Completers analysis (18/35) showed improvements on the Metacognition Assessment Scale (MAS-A) scales Self Reflectivity and metacognitive Mastery at follow-up. No effects were found on secondary outcomes.
On average, participants in the MERIT group were, based on MAS-A scores, at follow-up more likely to recognize their thoughts as changeable rather than as facts. MERIT might be useful for patients whose self-reflection is too limited to benefit from other therapies. Given how no changes were found in secondary measures, further research is needed. Limitations and suggestions for future research are discussed.

Decision makers consider all options in choice triplets
2025
Most contemporary decision-making research focuses on choices between only two alternative options, in spite of the fact that most real-world decisions involve more than two options. Beyond this practical point, multi-option decisions are also important from a theoretical perspective. Experimental and computational studies have demonstrated that the composition of a set of choice options has predictable effects on choice outcomes. Specifically, with more options available to choose from, responses are slower and more stochastic. This effect is amplified when the values of the options (including the worst option in the set) are more similar to each other. In this study, we provide further evidence of these known effects. We also provide evidence that metacognitive factors such as feelings of confidence in the response or mental effort exertion during deliberation show similar effects as the cognitive factors (consistency between choices and value estimates, response speed). Finally, we provide novel evidence that value estimates are refined during deliberation for all options in choice triplets, similar to what has previously been show for choice pairs.

For decades, research on
metacomprehension
has demonstrated that many learners struggle to accurately discriminate their comprehension of texts. However, while reviews of experimental studies on relative metacomprehension accuracy have found average intra-individual correlations between predictions and performance of around .27 for adult readers, in some contexts even lower near-zero accuracy levels have been reported. One possible explanation for those strikingly low levels of accuracy is the high conceptual overlap between topics of the texts. To test this hypothesis, in the present work participants were randomly assigned to read one of two text sets that differed in their degree of conceptual overlap. Participants judged their understanding and completed an inference test for each topic. Across two studies, mean relative accuracy was found to match typical baseline levels for the low-overlap text sets and was significantly lower for the high-overlap text sets. Results suggest text similarity is an important factor impacting comprehension monitoring accuracy that may have contributed to the variable and sometimes inconsistent results reported in the metacomprehension literature.

Randomized control trial to assess the efficacy of metacognitive training compared with a psycho-educational group in people with a recent-onset psychosis
2017
Aims were to assess the efficacy of metacognitive training (MCT) in people with a recent onset of psychosis in terms of symptoms as a primary outcome and metacognitive variables as a secondary outcome.
A multicenter, randomized, controlled clinical trial was performed. A total of 126 patients were randomized to an MCT or a psycho-educational intervention with cognitive-behavioral elements. The sample was composed of people with a recent onset of psychosis, recruited from nine public centers in Spain. The treatment consisted of eight weekly sessions for both groups. Patients were assessed at three time-points: baseline, post-treatment, and at 6 months follow-up. The evaluator was blinded to the condition of the patient. Symptoms were assessed with the PANSS and metacognition was assessed with a battery of questionnaires of cognitive biases and social cognition.
Both MCT and psycho-educational groups had improved symptoms post-treatment and at follow-up, with greater improvements in the MCT group. The MCT group was superior to the psycho-educational group on the Beck Cognitive Insight Scale (BCIS) total (p = 0.026) and self-certainty (p = 0.035) and dependence self-subscale of irrational beliefs, comparing baseline and post-treatment. Moreover, comparing baseline and follow-up, the MCT group was better than the psycho-educational group in self-reflectiveness on the BCIS (p = 0.047), total BCIS (p = 0.045), and intolerance to frustration (p = 0.014). Jumping to Conclusions (JTC) improved more in the MCT group than the psycho-educational group (p = 0.021). Regarding the comparison within each group, Theory of Mind (ToM), Personalizing Bias, and other subscales of irrational beliefs improved in the MCT group but not the psycho-educational group (p < 0.001-0.032).
MCT could be an effective psychological intervention for people with recent onset of psychosis in order to improve cognitive insight, JTC, and tolerance to frustration. It seems that MCT could be useful to improve symptoms, ToM, and personalizing bias.

Abstract
Background
In psychosis spectrum disorders, maladaptive mental imagery is associated with auditory verbal hallucinations (AVHs). This study evaluates the feasibility, acceptability, and effectiveness of the following 4 imagery techniques in targeting mental imagery and AVHs severity: Imagery Rescripting (ImRs), Promoting positive Imagery de novo (Pos-Im), Metacognitive Imagery techniques (Meta-Im), and playing Tetris.
Study Design
Four replicated single-case series experimental designs were used. Participants were randomized to 1 of the 4 treatment conditions. Primary, we measured the severity of mental imagery and AVHs thrice daily on an 11-point VAS scale during a 2-week baseline, throughout 3 weeks of therapy, and during a 2-week follow-up phase. Randomization tests were used to examine whether daily severity levels of momentary mental imagery and AVHs decreased post-therapy. Secondary, questionnaires assessing the severity of AVHs, mental imagery characteristics, and levels of mood, anxiety, and functioning were administered at baseline, before, and posttreatment.
Results
Twenty-eight participants completed all treatment sessions. Mental imagery significantly decreased after ImRs (P < .001, d = 1.13) and Pos-Im (P = .039, d = 0.22), with no significant effects observed following Meta-Im or Tetris. AVHs significantly decreased with all treatment conditions, with largest effects for ImRs (P = .001, d = 1.39) and Pos-Im (P < .001, d = 1.99). Secondary results demonstrated reductions in the severity of AVHs, mood, anxiety, imagery frequency, and appraisals.
Conclusions
Imagery techniques appear feasible and acceptable for addressing mental imagery and AVHs in the psychosis continuum and may be valuable additions to current treatment for AVHs.

Hydrocortisone decreases metacognitive efficiency independent of perceived stress
2020
It is well established that acute stress produces negative effects on high level cognitive functions. However, these effects could be due to the physiological components of the stress response (among which cortisol secretion is prominent), to its psychological concomitants (the thoughts generated by the stressor) or to any combination of those. Our study shows for the first time that the typical cortisol response to stress is sufficient to impair metacognition, that is the ability to monitor one’s own performance in a task. In a pharmacological protocol, we administered either 20 mg hydrocortisone or placebo to 46 male participants, and measured their subjective perception of stress, their performance in a perceptual task, and their metacognitive ability. We found that hydrocortisone selectively impaired metacognitive ability, without affecting task performance or creating a subjective state of stress. In other words, the single physiological response of stress produces a net effect on metacognition. These results inform our basic understanding of the physiological bases of metacognition. They are also relevant for applied or clinical research about situations involving stress, anxiety, depression, or simply cortisol use.

Abstract
Individualized metacognitive training (MCT+) is a novel psychotherapy that has been designed to specifically target delusional beliefs in people with psychosis. It works by developing an awareness of the implausible content of delusional beliefs, while also targeting the cognitive biases that contribute to their formation and maintenance. It was expected that MCT+ would lead to significantly greater reductions in delusional severity compared to a cognitive remediation (CR) active control condition. A total of 54 patients with a schizophrenia spectrum disorder and active delusions were randomized into four 2-hourly sessions of MCT+ (n = 27) or CR (n = 27). All participants completed posttreatment assessment, and only 2 participants did not complete 6-month follow-up assessment, resulting in MCT+ (n = 26) and CR (n = 26) for final analysis. The primary outcome measures of delusional and positive symptom severity were assessed rater-blind; secondary outcome assessment was non-blinded and included clinical and cognitive insight, the jumping to conclusions (JTC) bias, and cognitive functioning. Participants in the MCT+ condition showed significant reductions in delusional and overall positive symptom severity (large effect) and improved clinical insight (moderate effect) relative to CR controls. In contrast, CR controls showed moderate improvement in problem-solving ability relative to MCT+, but no other cognitive domain. Importantly, these findings were maintained at 6-month follow-up. The study adds further efficacy to the MCT program, and suggests that even brief psychotherapy can help to ameliorate the symptoms of psychosis.

EFL listening comprehension has been a stark challenge for language learners, but little is known about the combined effect of individual differences, such as working memory capacity, and metacognitive intervention. Thus, the present experimental study investigates the effect of metacognitive intervention on the listening performance and metacognitive awareness of high- and low-WMC EFL learners. For this purpose, Oxford Placement Tests were distributed among 120 male Iranian EFL learners, of which 94 were identified as intermediate. Then, backward visual digit span tests were administered to measure their working memory capacity. Based on the median of all scores, 80 learners were selected and randomly assigned to two experimental groups and two control groups each with 20 participants. Next, their performance on the International English Language Testing System and the Metacognitive Awareness Listening Questionnaire was measured before and after the 8-session metacognitive intervention. Results showed that high-WMC experimental learners had a higher gain with a large effect size in terms of listening performance compared with all the other groups. In addition, the experimental group learners reported the significantly higher use of the metacognitive strategies with a moderate effect size. Interestingly, low-WMC learners’ listening performance and metacognitive awareness also improved as a result of the intervention. Our findings bear pedagogical significance in that individual differences in WMC should be considered more in both EFL language classes and the future line of research involving the metacognitive intervention.

How Much Do Metamemory Beliefs Contribute to the Font-Size Effect in Judgments of Learning?
2015
Evidence shows that the font size of study items significantly influences judgments of learning (JOLs) and that people's JOLs are generally higher for larger words than for smaller words. Previous studies have suggested that font size influences JOLs in a belief-based way. However, few studies have directly examined how much people's beliefs contribute to the font-size effect in JOLs. This study investigated the degree to which font size influenced JOLs in a belief-based way. In Experiment 1, one group of participants (learners) studied words with different font sizes and made JOLs, whereas another group of participants (observers) viewed the learners' study phase and made JOLs for the learners. In Experiment 2, participants made both JOLs and belief-based recall predictions for large and small words. Our results suggest that metamemory beliefs play an important role in the font-size effect in JOLs.

Schizophrenia is a complex psychiatric disorder with unknown and presumably heterogeneous etiology. While the disorder can have various outcomes, research is predominantly “deficit-oriented” emphasizing the hardship that the disorder inflicts on sufferers as well as their families and society. Beyond symptom reduction, imparting patients with hope and meaning in life is increasingly considered an important treatment target, which may raise self-esteem, and reduce self-stigma and suicidal ideation. The present study compared a psychotherapeutic treatment aimed at improving cognitive insight, individualized metacognitive intervention (MCT+), with an active control in order to elucidate if personal meaning-making and hope can be improved in patients with psychosis across time. A total of 92 patients were randomized to either individualized metacognitive therapy (MCT+) or CogPack (neuropsychological training) and followed up for up to 6 months. The “Subjective Sense in Psychosis Questionnaire” (SUSE) was administered which covers different salutogenetic vs pathogenetic views of the disorder, valence of symptom experiences and the consequences of psychosis. Patients in the MCT+ group showed a significant positive shift in attitudes towards the consequences of their illness over time relative to patients in the active control condition. There was some evidence that MCT+ also enhanced meaning-making. The perceived negative consequences of psychosis were highly correlated with depression and low self-esteem, as well as suicidality. The study shows that a cognitive insight training can improve meaning-making in patients and help them come to terms with their diagnosis.
