Does Mindfulness Enhance Critical Thinking? Evidence for the Mediating Effects of Executive Functioning in the Relationship between Mindfulness and Critical Thinking

Ethics and Meditation: A New Educational Combination to Boost Verbal Creativity and Sense of Responsibility

Both creativity and responsibility are important higher-order skills to develop to meet the challenges of the Anthropocene, and both are related to attentional states of consciousness and to ethics. Meditation is a set of practices that trains attentional and emotional regulation. A few studies have shown that different kinds of meditation can foster different kinds of creative thinking, and others have begun to investigate the effect of the combination of meditation and ethics on ethical characteristics (but not yet on creativity or precisely on responsibility, so far). Here, we present a nonrandomized trial with an active control group among second-year science university students (n = 84) to test the effect of the secular Meditation-Based Ethics of Responsibility (MBER) program on creative potential, self-reported awareness, and sense of one's own responsibility. The results show a large effect of the program on sense of one's own responsibility and convergent and divergent creative writing tasks, both in conceptual-semantic and engineering-like verbal ideation. They also suggest that convergent conceptual-semantic thinking might moderate the effect of the MBER program on the awareness and sense of one's own responsibility. This work opens up new research and educational perspectives linked to necessary behavioral changes in the Anthropocene.

How to counter the anti-vaccine rhetoric: Filling information voids and building resilience

Widely circulating anti-vaccine misinformation online has been constituting a large obstacle for the success of COVID-19 vaccination campaigns and for the well-being of people during the pandemic. In this paper we discuss strategies to mitigate negative effects of online anti-vaccine contents on public health and to prevent hesitant individuals from falling prey of the traps set by anti-vaccine disinformation spreaders. Here we discuss the importance of filling information voids and understanding trends and concerns that shape the vaccine debate, and we highlight the relevance of building resilience to vaccine misinformation by strengthening public health and digital literacy.

Investigating mindfulness influences on cognitive function: On the promise and potential of converging research strategies

Research investigating the effects and underlying mechanisms of mindfulness on cognitive functioning has accelerated exponentially over the past two decades. Despite the rapid growth of the literature and its influential role in garnering public interest in mindfulness, inconsistent methods in defining and measuring mindfulness have yielded variable findings, which contribute to the overall dearth of clear generalizable conclusions. The focus of this article is to address the lack of cohesion in the collective methodologies used in this domain by providing a new perspective grounded in classic cognitive and experimental psychology principles. We leverage the concept of converging operations to demonstrate how seemingly disparate research strategies can be integrated towards a more unified and systematic approach. An organizing taxonomic framework is described to provide useful structure in how mindfulness can be operationalized, measured, and investigated. We illustrate the rationale and core organizing principles of the framework through a selective review of studies on mindfulness and cognitive control. We then demonstrate the utility of the approach by showing how it can be applied to synthesize extant methodologies and guide the development of future research. Specific suggestions and examples pertaining to experimental design and statistical analysis are provided.

Psychometric properties of the critical thinking disposition assessment test amongst medical students in China: a cross-sectional study

BACKGROUND

Critical thinking disposition helps medical students and professionals overcome the effects of personal values and beliefs when exercising clinical judgment. The lack of effective instruments to measure critical thinking disposition in medical students has become an obstacle for training and evaluating students in undergraduate programs in China. The aim of this study was to evaluate the psychometric properties of the CTDA test.

METHODS

A total of 278 students participated in this study and responded to the CTDA test. Cronbach's α coefficient, internal consistency, test-retest reliability, floor effects and ceiling effects were measured to assess the reliability of the questionnaire. Construct validity of the pre-specified three-domain structure of the CTDA was evaluated by explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). The convergent validity and discriminant validity were also analyzed.

RESULTS

Cronbach's alpha coefficient for the entire questionnaire was calculated to be 0.92, all of the domains showed acceptable internal consistency (0.81-0.86), and the test-retest reliability indicated acceptable intra-class correlation coefficients (ICCs) (0.93, p < 0.01). The EFA and the CFA demonstrated that the three-domain model fitted the data adequately. The test showed satisfactory convergent and discriminant validity.

CONCLUSIONS

The CTDA is a reliable and valid questionnaire to evaluate the disposition of medical students towards critical thinking in China and can reasonably be applied in critical thinking programs and medical education research.

Dynamics of the Sphere Model of Consciousness: Silence, Space, and Self

The Sphere Model of Consciousness (SMC) delineates a sphere-shaped matrix that aims to describe subjective experiences using geometric coordinates, in accordance with a neurophenomenological perspective. According to the SMC, an experience of overcoming the habitual self and the conditioning of memories could be placed at the center of the matrix, which can then be called the Place of Pre-Existence (PPE). The PPE is causally associated with self-determination. In this context, we suggest that silence could be considered an intentional inner environment enabling self-perception to focus on the “here and now,” which in turn improves perception of one’s own body in space. To investigate the hypotheses grounded in the model, the current preliminary study examined the Place of Pre-Existence Technique (PPEt), in which practitioners are guided to focus on a self-defined aim, reach a state of detachment from the habitual self, and envision the future. Four-hundred eighty-one volunteer PPEt practitioners completed self-report questionnaires before and after an intensive 3-day meditative training. We analyzed potential relationships between subjective experiences related to physical, emotional, mental, temporal, and spatial components, as well as self-determination and silence, before and after training. The results indicated a transition from a prevailing influence of mental dimension on the other aspects of experience, to a prevailing influence of the spatial dimension. Silence was reported more often following the training and was predominantly related to mental and emotional experiences. The results are discussed in the framework of the SMC, as compared to other models, and in relation to the shift from Narrative to Minimal Self and to increased balance among the considered dimensions.

How does brief guided mindfulness meditation enhance empathic concern in novice meditators?: A pilot test of the suggestion hypothesis vs. the mindfulness hypothesis

Despite the widespread popularity of mindfulness meditation for its various benefits, the mechanism underlying the meditation process has rarely been explored. Here, we present two preliminary studies designed to test alternative hypotheses: whether the effect of brief guided mindfulness meditation on empathic concern arises from verbal suggestion (suggestion hypothesis) or as a byproduct of an induced mindfulness state (mindfulness hypothesis). Study 1 was a pilot randomized control trial of sitting (breath-and-body) meditation vs. compassion meditation that provided preliminary support for the mindfulness hypothesis. Study 2 was set up to rule out the possibility that the meditation effects observed in Study 1 were the effects of repeated measures. An inactive control group of participants underwent the repeated measures of empathic concern with no meditation in between. The pre-post comparison demonstrated no significant changes in the measures. Thus, the results of two studies supported the mindfulness hypothesis. Limitations of the present study and future research directions are discussed.

Dual mechanisms of cognitive control in mindful individuals

Not much research has adopted a multicomponent approach to examine the relationship between mindfulness and cognitive control. Studies addressing this issue have produced mixed results that may be due to the incorporation of different questionnaires to assess mindfulness and to the assessment of different stages and types of mindfulness itself. In the present study, we aimed to investigate to which extent dispositional mindfulness relates to a dynamic use of control modes as understood from the dual mechanisms of control theory. Further, we aimed to test this hypothesis by including two different frequently used mindfulness questionnaires in order to explore their confluence. Hundred thirty young adults completed two well-established assessment tools of mindfulness (Mindful Attention Awareness Scale and Five Facets Mindfulness Questionnaire) and two well-validated experimental tasks measuring proactive/reactive control modes (AX-Continuous Performance Task and Cued Task-Switching Paradigm). The data analyses were performed considering the continuous values in multiple regression analyses, as it is thought to better capture individual differences. The results replicate the previous findings suggesting that mindful individuals tend to use proactive and reactive control in a balanced manner in comparison to low mindfulness individuals, who tend to rely more on proactive control. Moreover, mindful individuals showed greater flexibility when the two processing modes were available. Hence, the major effects were found by using the two questionnaires. Altogether our findings indicate that mindful individuals, who have been characterized by an enhanced focus on the present moment without judgment, are less attached to the previous contextual information, which allows them to exhibit a more flexible performance.

Mindfulness Training for Improving Attention Regulation in University Students: Is It Effective? and Do Yoga and Homework Matter?

The present study examined the effects of mindfulness training on attention regulation in university students and whether the potential benefits of implementation are influenced by the yoga component of mindfulness-based interventions (MBIs) and/or by MBI homework practice. In a non-randomized trial with pre- and post-assessments, n = 180 university students were allocated to either mindfulness training (experimental groups), awareness activities (active control group), or no training (passive control group). Mindfulness was taught through two MBIs, one including yoga and the other excluding yoga. Attention regulation was operationalized via behavioral indicators, namely sustained attention, cognitive flexibility, cognitive inhibition, and data-driven information processing. With the exception of speed in a cognitive flexibility task, the results indicated no systematic or differential advantage arising from mindfulness training, with or without yoga, regarding the aspects of attention regulation. There was no consistent influence of homework quantity or quality. The implications for mindfulness training in academic contexts are discussed.

The Bilingual Advantage in Thinking Critically: The Roles of Age of Onset and L2 Proficiency

The bilingual advantage and its effect on executive function (EF) are among the major concerns of researchers in the field of bilingualism. Nevertheless, the bilingual effect on critical thinking has not yet received the attention it truly deserves. The present study aimed to investigate the bilingual effect on critical thinking disposition (CTD) and its relationship to age, age of onset (AoO), and L2 proficiency. An experimental design was adopted to study the impact of bilingualism on CTD. Correlational designs were then used to investigate the association between L2 proficiency and age of bilinguals with their CTD scores. The sample included 286 participants, consisting of 143 bilinguals, carefully matched with 143 monolinguals based on age and socioeconomic status. The bilinguals were then divided into two groups of early bilinguals (AoO = 10 years or less) and late bilinguals (AoO = 11 years or more). Their L2 proficiency and performance on the University of Florida Critical Thinking Disposition Inventory were measured and compared. The results indicate an advantage in CTD in favor of the bilinguals, with no significant difference between early and late bilinguals. A larger effect size was observed with an elevation in the age of the bilinguals. A positive association was found between L2 proficiency and the bilinguals’ CTD, with a weak correlation between education and CTD scores. The results are also compared with those of the bilingual effect on EF.

Clinical Reasoning in Physical Therapy: A Concept Analysis

BACKGROUND

Physical therapy, along with most health professions, struggles to describe clinical reasoning, despite it being a vital skill in effective patient care. This lack of a unified conceptualization of clinical reasoning leads to variable and inconsistent teaching, assessment, and research.

OBJECTIVE

The objective was to conceptualize a broad description of physical therapists' clinical reasoning grounded in the published literature and to unify understanding for future work related to teaching, assessment, and research.

DESIGN/METHODS

The design included a systematic concept analysis using Rodgers' evolutionary methodology. A concept analysis is a research methodology in which a concept's characteristics and the relation between features of the concept are clarified.

RESULTS

Based on findings in the literature, clinical reasoning in physical therapy was conceptualized as integrating cognitive, psychomotor, and affective skills. It is contextual in nature and involves both therapist and client perspectives. It is adaptive, iterative, and collaborative with the intended outcome being a biopsychosocial approach to patient/client management.

LIMITATIONS

Although a comprehensive approach was intended, it is possible that the search methods or reduction of the literature were incomplete or key sources were mistakenly excluded.

CONCLUSIONS

A description of clinical reasoning in physical therapy was conceptualized, as it currently exists in representative literature. The intent is for it to contribute to the unification of an understanding of how clinical reasoning has been conceptualized to date by practitioners, academicians, and clinical educators. Substantial work remains to further develop the concept of clinical reasoning for physical therapy, including the role of movement in our reasoning in practice.

Does mindfulness training modulate the influence of spatial attention on the processing of intracutaneous electrical stimuli?

Mindfulness based stress reduction (MBSR) training has been proposed to improve attentional skills by modulating thalamo-cortical loops that affect the sensitivity of relevant cortical areas like the somatosensory cortex. This modulation may be reflected in the electroencephalographic (EEG) alpha rhythm, and could affect the processing of subsequently applied intracutaneous electrical stimuli. Participants took part in an MBSR training and participated in two EEG sessions. EEG was measured in variants of an endogenous orienting paradigm in which attention had to be directed to the left or right forearm. After the orienting interval, the electrical stimulus was applied, equally likely on the attended or the unattended forearm. One group of participants took part in the EEG session before and after the training, while the other group took part after the training, and another time, eight weeks later. The influence of the MBSR training and spatial attention were examined with behavioral measures, lateralized alpha power within the orienting interval, and with event-related potentials (ERPs) evoked by the electrical stimuli. Self-reported mindfulness was clearly affected by the training, but no influence was found on other behavioral measures. Alpha power was clearly lateralized due to spatial attention and several ERP components (N130, N180, P340) were modulated by spatial attention but no support was found for an influence of the MBSR training. Finally, analyses revealed that individual differences in training time modulated some of the observed effects, but no support was found for an influence on attentional orienting.

The Central Executive Mediates the Relationship Between Children's Approximate Number System Acuity and Arithmetic Strategy Utilization in Computational Estimation

Studies investigating the relationship between working memory (WM) and approximate number system (ANS) acuity in the area of arithmetic strategy utilization are scarce. The choice/no choice method paradigm was used in the present study to determine whether and how ANS acuity and WM components affected strategy utilization. The results showed that the central executive (CE) mediated the relationship between ANS acuity and strategy utilization. Furthermore, quantile regression analyses revealed that the association between CE and strategy choice was robust from the first to highest quantile. Notably, the relationship between ANS acuity and strategy choice was significant at the median and higher quantiles (i.e., 0.5, 0.75, and 0.85 quantiles), but not significant at lower quantiles (i.e., 0.15 and 0.25 quantiles). These results suggest that domain-general skills play a crucial role in the relationship between children's ANS acuity and mathematical ability. The impact of ANS acuity and CE on strategy choice was dependent on the distribution of the strategy utilization level. These results provide a further understanding of the utilization of cognitive strategies.

The Effect of Mindfulness Training on Proactive and Reactive Cognitive Control

Previous studies have demonstrated that mindfulness practice can improve general cognitive control. However, little research has examined whether mindfulness practices affect different cognitive control strategies. According to the dual mechanisms of control (DMC) model, different cognitive control strategies may play distinct roles in individuals' lives. Proactive control allows people to maintain and prepare for goals, whereas reactive control allows them to respond flexibly to a changing environment. Thus, this study investigates the influences of mindfulness training on proactive and reactive control measured by the AX version of the Continuous Performance Test (AX-CPT). Thirty participants completed AX-CPT and the Five Facet Mindfulness Questionnaire (FFMQ) before and after random assignment to either an 8-week mindfulness training group or a control group. The results showed no interaction between group and test time for AY or BX trial type, but the training group had fewer post-test errors on the BX trial and a higher Behavior Shift Index (BSI) of reaction time (RT) compared with the control group. This finding indicates enhanced trend of proactive control with mindfulness training. A positive correlation between the BSI of RT and observing scores on the FFMQ confirmed the connection between attentional components in mindfulness and proactive control. Errors on the AY trial in the post-test decreased in both groups, reflecting reactive control that did not differ between groups. The 8-week mindfulness training demonstrates a potential improvement effect on proactive control and could be helpful in overcoming interference.

A randomised active-controlled trial to examine the effects of an online mindfulness intervention on executive control, critical thinking and key thinking dispositions in a university student sample

BACKGROUND

Arguments for including mindfulness instruction in higher education have included claims about the benefits of mindfulness practice for critical thinking. While there is theoretical support for this claim, empirical support is limited. The aim of this study was to test this claim by investigating the effects of an online mindfulness intervention on executive function, critical thinking skills and associated thinking dispositions.

METHOD

Participants recruited from a university were randomly allocated, following screening, to either a mindfulness meditation group or a sham meditation group. Both the researchers and the participants were blind to group allocation. The intervention content for both groups was delivered through the Headspace online application, an application which provides guided meditations to users. Both groups were requested to complete 30 guided mindfulness meditation sessions across a 6 week period. Primary outcome measures assessed mindfulness, executive functioning, critical thinking, actively open-minded thinking and need for cognition. Secondary outcome measures assessed wellbeing, positive and negative affect, and real-world outcomes.

RESULTS

In a series of full-information maximum likelihood analyses, significant increases in mindfulness dispositions and critical thinking scores were observed in both the mindfulness meditation and sham meditation groups. However, no significant effects of group allocation were observed for either primary or secondary measures. Furthermore, mediation analyses testing the indirect effect of group allocation through executive functioning performance did not reveal a significant result and moderation analyses showed that the effect of the intervention did not depend on baseline levels of the key thinking dispositions, actively open-minded thinking and need for cognition.

CONCLUSION

No evidence was found to suggest that engaging in guided mindfulness practice for 6 weeks using the online intervention method applied in this study improves critical thinking performance. While further research is warranted, claims regarding the benefits of mindfulness practice for critical thinking should be tempered in the meantime.

TRIAL REGISTRATION

The study was initially registered in the AEA Social Science Registry before the recruitment was initiated (RCT ID: AEARCTR-0000756; 14/11/2015) and retrospectively registered in the ISRCTN registry ( RCT ID: ISRCTN16588423 ) in line with requirements for publishing the study protocol.

Biofunctional Understanding and Conceptual Control: Searching for Systematic Consensus in Systemic Cohesion

For first generation scientists after the cognitive revolution, knowers were in active control over all (stages of) information processing. Then, following a decade of transition shaped by intense controversy, embodied cognition emerged and suggested sources of control other than those implied by metaphysical information processing. With a thematic focus on embodiment science and an eye toward systematic consensus in systemic cohesion, the present study explores the roles of biofunctional and conceptual control processes in the wholetheme spiral of biofunctional understanding (see Iran-Nejad and Irannejad, 2017b, Figure 1). According to this spiral, each of the two kinds of understanding has its own unique set of knower control processes. For conceptual understanding (CU), knowers have deliberate attention-allocation control over their first-person "knowthat" and "knowhow" content combined as mutually coherent corequisites. For biofunctional understanding (BU), knowers have attention-allocation control only over their knowthat content but knowhow control content is ordinarily conspicuously absent. To test the hypothesis of differences in the manner of control between CU and BU, participants in two experiments read identical-format statements for internal consistency, as response time was recorded. The results of Experiment 1 supported the hypothesis of differences in the manner of control between the two types of control processes; and Experiment 2 confirmed the results of Experiment 1. These findings are discussed in terms of the predicted differences between BU and CU control processes, their roles in regulating the physically unobservable flow of systemic cohesion in the wholetheme spiral, and a proposal for systematic consensus in systemic cohesion to serve as the second guiding principle in biofunctional embodiment science next to physical science's first guiding principle of systematic observation.

A protocol for a randomised active-controlled trial to evaluate the effects of an online mindfulness intervention on executive control, critical thinking and key thinking dispositions in a university student sample

BACKGROUND

While most modern research focuses on the clinical benefits of mindfulness, an emerging body of work suggests that mindfulness can facilitate self-regulation of everyday thinking in typically developing individuals. This behaviour is best captured using critical thinking assessments. The aim of this paper is to describe a rigorous, pre-registered study which will investigate the effect of an online mindfulness intervention on Executive Functioning, critical thinking skills and associated thinking dispositions.

METHOD

The design employed is a randomised-controlled 2 (condition) X 2 (time) parallel-group design which is explanatory in nature. A sample of at least 60 participants will be recruited from the pool of students at NUI Galway, with those between the ages of 18 and 65 with an adequate level of English included. Participants will be randomly assigned following screening, using block randomisation with a fixed block of 6 and a 1:1 ratio, to either the mindfulness meditation group or a sham meditation group. Both groups will be given access to the Headspace app. This is an app which provides guided meditations to users. Participants in each group will receive unique codes granting access to either the experimental or active-control intervention materials. Group allocation will be double-blinded. The primary outcome measures will assess mindfulness, executive functioning, critical thinking, actively open-minded thinking and need for cognition. Secondary outcome measures will assess eudaimonic and hedonic wellbeing, positive and negative affect, and real-world outcomes. These will be measured at baseline and at the end of the intervention. Manipulation checks will assess adherence to the intervention, meditation quality and task difficulty and enjoyment.

DISCUSSION

If this intervention proves effective, it will show the potential of mindfulness practice to facilitate everyday critical thinking and should stimulate more interest in this line of research. If ineffective, claims regarding mindfulness and thinking skills should be tempered. This research was funded by a Galway Doctoral Research Scholarship awarded to the first author and was facilitated by Headspace Inc. who provided the intervention materials. The trial is registered in the ISRCTN registry and any protocol amendments will be recorded there (RCT ID: ISRCTN16588423. Registered 7th January 2016).
