Verification of the effectiveness of motor imagery (MI) has mainly focused on the method of implementing MI, and few studies have assessed individual factors. This study examined the individual differences in MI effects from the viewpoint of the multiple components of working memory. Forty-six healthy subjects (mean age 20.8 years) performed the Stroop Test (central executive within working memory) and reverse chanting (phonological loop within working memory). Then, F-waves were measured at rest for 30 s, the Purdue Pegboard was performed with the non-dominant hand to evaluate finger dexterity (Peg score) before MI, F-waves were measured during 30 s of kinesthetic MI, and the Peg score was evaluated after MI. For statistical analysis, the amplitude F/M ratio and Peg score were used as dependent variables, and the subjects were divided into Good and Poor groups according to cognitive function. The results showed an interaction for the amplitude F/M ratio and Peg score when grouped by reverse inverse chanting. In the subsequent simple main effect analysis, the Peg score was significantly improved after MI in both groups. The amplitude F/M ratio was significantly increased during MI compared to the resting state only in the Poor phonological loop group. Conversely, there was no interaction when the groups were divided by Stroop interference. No relationship was found between individual differences in central executive and changes in hand finger dexterity and spinal motor nerve excitability induced by MI. However, there may be a relationship between individual differences in phonological loops and changes in MI-induced finger dexterity and spinal motor nerve excitability.

This review explores the multifaceted nature of age-related decline in source memory and associative memory. The review highlights the potential effects of age-related decline in these types of memory. By integrating insights from behavioral, cognitive, and neuroscientific research, it examines how encoding, retrieval, and neural mechanisms influence this decline. Understanding these processes is critical to alleviate memory decline in older adults. Directing attention to source information during encoding, employing unitization techniques to strengthen memory associations, and utilizing metacognitive strategies to focus on relevant details show promise in enhancing memory retrieval for older adults. However, the review acknowledges limitations in processing resources and executive function, necessitating a nuanced approach to the complexities of age-related decline. In conclusion, this review underscores the importance of understanding the complexities of age-related source and associative memory decline and the potential benefits of specific cognitive strategies. It emphasizes the need for continued research on age-related memory function to improve the quality of life for aging populations.

The current study focuses on how autistic adults utilize context to determine whether ambiguous utterances (e.g., "I'm thirsty") are intended as indirect requests or as literal comment/questions. Two questions are addressed: (1) How do autistic adults compare to neurotypical adults in using context to interpret an utterance's intention as either literal or a request? (2) What cognitive mechanisms correlate with indirect request interpretation, and are these different for participants in each group? Twenty-six autistic and 26 neurotypical college students participated, engaging in an online experiment where they read narratives that ended with utterances open to literal or request interpretations, based on context. After each narrative, participants selected the best paraphrase of the utterance from two options, literal versus request. Following this task, participants completed two mentalizing measures (a false belief and emotion-identification task) and several executive functioning tests. The best model for predicting paraphrase choice included scores on the emotion-identification task and context as main effects, along with the interaction between both. Participants with higher emotion-identification test scores were more likely to provide correct paraphrases. Models including group as a main effect and/or interaction were not better at fitting the data, nor were any models that included executive functioning measures as main effects or interactions. Emotion-identification test scores, but not autism diagnosis, predict how adults infer whether an utterance is a request. Findings suggest that autistic adults use context similarly to neurotypical adults when interpreting requests, and that similar processes underlie performance for each group.

Retrieving information from memory enhances long-term retention. In this manuscript, we describe the dual-memory framework, which makes interval-scale predictions of the magnitude of this retrieval practice effect. After outlining the framework, we use data from our laboratory—both at the group level and at the distribution level—to fit the equations from the dual-memory framework. Overall, we successfully fitted the model predictions to the observed average data. In addition, we compared the predicted and the observed distributions of performance in the retrieval practice condition. More importantly, we introduce a useful approach to simulate empirical scenarios and test the relationship between individual-difference variables and the retrieval practice effect. We illustrate the application of this approach using data from a study that measured fluid intelligence. Future studies may benefit from contrasting different strength-based frameworks.

Dynamic assessment is an approach that aims to improve student performance through interventions. One of the important application areas of dynamic assessment is the assessment of intelligence. Within the scope of the study, after a Cognitive intervention program (CIP) was developed, its effects on intelligence scores were examined with a quasi-experimental research method. The CIP was prepared by adopting a dynamic assessment approach to improve the performance of students with expert support. This improvement would be provided by the clues and feedback given during the intervention within the scope of the CIP. The sample of the study included 173 students in the 5–6 age group (83 experimental group, 90 control group). The CIP developed by the researcher consisted of 54 worksheets and was applied to the experimental group for 9 weeks. The implementation of the worksheets was supervised by classroom teachers. The digital application of the Anadolu-Sak Intelligence Scale (d-ASIS) and Raven’s colored progressive matrices (RCPM) were applied to both the experimental and control groups as pretests and posttests. The increases in the intelligence scores of the experimental and control groups were analyzed by MANOVA. The analysis showed that the intelligence levels of the experimental group increased significantly more than the control group in terms of both d-ASIS and RCPM total gain scores (posttest to pretest). This result indicated that the CIP, which was developed by adopting a dynamic assessment approach, supported cognitive development.

People's preferences for the utilitarian outcome in sacrificial moral dilemmas, where a larger group of individuals are saved at the cost of a few, have been argued to be influenced by various factors. Taking expected utility (EU) theory into consideration, we investigate whether the expected effectiveness of actions elucidate certain inconsistencies in moral judgments. Additionally, we also explore whether participants' role in the dilemma as the executor or a superior who merely makes a decision, which is carried out by a subordinate, influences judgments-a factor generally overlooked by classical EU models. We test these hypotheses using a modified moral dilemma paradigm with a choice between two actions, one highly successful and the other more likely to fail. Both actions are either expected to result in a favorable outcome of saving five individuals by sacrificing one or an unfavorable outcome of sacrificing five to save one. When the efficient action is anticipated to lead to a favorable outcome, in line with EU models, people almost invariably choose the efficient action. However, in conditions where the EUs associated with efficient and inefficient actions are close to each other, people's choice for favored outcome is above chance when they act as agents themselves. We discuss the implications of our results for existing theories of moral judgments.

Critical thinking as one of the key skills for success in the 21st-century has been considered by many scholars in teacher education. This study tries to examine the interaction of critical thinking disposition with two other key characteristics of successful teachers: cognitive flexibility and self-efficacy. To this end, a sample of pre-service English as a Foreign Language (EFL) teachers was selected for this study. Based on the findings, a positive and strong relationship between cognitive flexibility and critical thinking disposition, and a positive and robust correlation between self-efficacy and critical thinking disposition were observed. Hence, it can be suggested that teacher-educationists can use this link for designing teacher-training courses with tailored tasks for both in and pre-service teachers. The main contribution of the findings might be beneficial for homogenizing teacher-training courses around the globe with the 21st-century trends. In addition, this line of research can be followed by empirical studies for checking the effectiveness of tailored tasks for provoking teachers' critical thinking dispositions, cognitive flexibility, and self-efficacy in teaching activities.

This study explored whether instructing participants to make forward or backward joystick movements in response to morality words is consistent with the conceptual metaphor MORAL IS MOVING FORWARD/IMMORAL IS MOVING BACKWARD in Chinese-English bilinguals' first and second languages. Chinese-English bilinguals were instructed to categorize words as moral or immoral while moving a joystick in a compatible block (moral-forward, immoral-backward) and an incompatible block (moral-backward, immoral-forward). The results revealed three main conclusions: First, participants showed faster categorization of immoral words when their responses involved backward joystick movements compared to forward joystick movements. Second, participants also demonstrated a slightly faster categorization of moral words when their responses involved backward joystick movements compared to forward joystick movements. Third, Chinese morality words were categorized faster overall than English morality words. However, despite a slightly larger effect size observed in L1, the action compatibility effects for morality words exhibited a similar pattern across both languages. In sum, bilinguals showed shared access to the IMMORAL IS MOVING BACKWARD conceptual metaphor across both L1 and L2, but they did not access the MORAL IS MOVING FORWARD conceptual metaphor in either L1 or L2. This study provides new evidence supporting the conceptual metaphor theory.

Metaphorical sentences are assumed to be related to more costly processes than their literal counterparts. However, given their frequent use in our daily lives, metaphorical sentences "must come with a benefit" (Noveck et al. Metaphor Symb 16:109-121. https://doi.org/10.1080/10926488.2001.9678889 , 2001). In this paper, we investigated whether metaphorical sentences were better remembered than their literal counterparts. In addition, we were interested in assessing whether the relevance of the metaphors impacted this recall. Anchoring this hypothesis in the appraisal theory, we hypothesized that food-related metaphorical sentences may be particularly relevant when one is hungry, and consequently, be better remembered in that particular physiological state. Participants were presented with randomized metaphorical sentences and their literal counterparts and were later asked to remember the missing word in both metaphorical and literal sentences. General mixed model analyses revealed that metaphorical sentences were better remembered. However, there was no significant effect of hunger. We discuss these results in relation to (1) the metaphor literature and (2) the appraisal theory of emotion.
