The cognitive flexibility inventory (CFI) was developed to be a brief self-report measure of the type of cognitive flexibility necessary for individuals to successfully challenge and replace maladaptive thoughts with more balanced and adaptive thinking. It was designed to measure three aspects of cognitive flexibility: (a) the tendency to perceive difficult situations as controllable; (b) the ability to perceive multiple alternative explanations for life occurrences and human behavior; and (c) the ability to generate multiple alternative solutions to difficult situations. The two studies presented in this manuscript describe the initial development of the CFI and a 7-week longitudinal study. Results from these studies indicate the CFI has a reliable two-factor structure, excellent internal consistency, and high 7-week test–retest reliability. Preliminary evidence was obtained for the CFI’s convergent construct validity via the CFI’s correlations with other measures of cognitive flexibility (Cognitive Flexibility Scale) and coping (Ways of Coping Checklist-Revised), respectively. Support was also demonstrated for the concurrent construct validity of the CFI via its correlation with the BDI-II. Further research is needed to investigate the reliability and validity of the CFI among clinical populations.

Cardiovascular diseases such as coronary artery disease (CAD) have a high prevalence of psychiatric comorbidities, that may impact clinically relevant outcomes (e.g., cognitive impairment and executive dysfunction). Obsessive-compulsive personality disorder (OCPD) is a common psychiatric comorbidity in CAD. It has a distinct cognitive profile characterised by inflexible thinking and executive dysfunction, which in turn may affect treatment adherence. However, the impact of OCPD on cognitive functioning in CAD is under-researched. We aimed to investigate the impact of OCPD on executive function in individuals with CAD undergoing rehabilitation, using cognitive tests relating to inflexibility and executive planning. Seventy-eight adults (median age 59 [53.0–66.0] years) with CAD were tested within three days of hospital admission for cardiac rehabilitation occurring within two weeks of experiencing an episode of unstable angina or myocardial infarction. The Compulsive Personality Assessment Scale (CPAS) was used to evaluate OCPD traits. Neurocognitive testing was performed using the Cambridge Automated Neuropsychological Test Battery (CANTAB) including tests of set shifting (Intra-Extra Dimensional [IED] Set Shifting), and executive planning (Stockings of Cambridge [SOC]). Ten individuals with CAD fulfilled the operational criteria for DSM-5 OCPD. Individuals with comorbid OCPD made more IED intra-dimensional shift reversal errors (2.0 [2.0–4.0] vs. 1.0 [1.0–2.0], p = .004), reflecting a difficulty inhibiting previously learnt responses. When all participants were analysed as a group, negative associations were found between individual OCPD traits and other aspects of cognitive performance. Hoarding trait was associated with increased initial thinking time on the SOC at five moves (ρ = 0.242, p = .033), while the need for control and rigidity traits were each associated with increased initial thinking time on the SOC at two moves (respectively, ρ = 0.259, p = .022; ρ = 0.239, p = .035), reflecting slower executive planning. A preoccupation with details trait was associated with fewer errors on a compound discrimination stage of the IED (ρ = −0.251, p = .026). After controlling these correlations for gender and age, significant associations remained with hoarding (β = 0.243, p = .036), need for control (β = 0.341, p = .005) and rigidity (β = 0.259, p = .038) traits. Preliminary evidence suggests that individuals with CAD and comorbid OCPD traits show greater inflexibility than those without OCPD. Several OCPD traits were associated with slower planning, even after controlling them for age and gender. This may have implications for the success of rehabilitation. •We investigated the impact of OCPD on executive function in individuals with CAD undergoing rehabilitation.•Individuals with comorbid OCPD had more difficulties in inhibiting previously learned responses.•Traits hoarding, rigidity, and need for control showed slower executive planning.•Individuals with CAD and comorbid OCPD and its traits show greater cognitive inflexibility than those without OCPD.

Pre-service teachers (PSTs) of English as a Foreign Language (EFL) need extensive training, preparing them for challenges encountered in real classrooms. Such challenges include presenting the target content knowledge in front of the class and promptly responding to students’ questions on the content. High-immersion virtual reality (VR) is increasingly seen as technology facilitating teacher training. When integrated with Artificial Intelligence (AI), VR simulations can enhance teacher education by providing real-world practice opportunities. Drawing on cognitive flexibility theory (CFT), this case study investigated how pre-service EFL teachers ( N  = 17) in Poland interpret the VR-AI–assisted simulation designed to facilitate their content knowledge application. The results suggest that such simulations are valuable for professional development and reflective practice regarding content knowledge in pre-service EFL teacher training. The findings contribute to the broader understanding of the integration of VR and AI technology in language teachers’ training programs aiming to support the application of content knowledge in real-life classrooms.

Background Cognitive flexibility refers to the capacity to shift between conceptual representations particularly in response to changes in instruction and feedback. It enables individuals to swiftly adapt to changes in their environment and has significant implications for learning. The present study focuses on investigating changes in cognitive flexibility following an intervention programme—Structure Learning training. Methods Participants are pseudo-randomised to either the Training or Control group, while matched on age, sex, intelligence and cognitive flexibility performance. In the Training group, participants undergo around 2 weeks of training (at least 13 sessions) on Structure Learning. In the Control group, participants do not have to undergo any training and are never exposed to the Structure Learning task. The effects of Structure Learning training are investigated at both the behavioural and neural level. We measured covariates that can influence an individual’s training performance before the training phase and outcome measures that can potentially show training benefits after the training phase. At the behavioural level, we investigated outcomes in both cognitive and social aspects with a primary focus on executive functions. At the neural level, we employed a multimodality approach and investigated potential changes to functional connectivity patterns, neurometabolite concentration in the frontal brain regions, and brain microstructure and myelination. Discussion We reported the development of a novel training programme based on Structure Learning that aims to hone a general learning ability to potentially achieve extensive transfer benefits across various cognitive constructs. Potential transfer benefits can be exhibited through better performance in outcome measures between Training and Control participants, and positive associations between training performance and outcomes after the training in Training participants. Moreover, we attempt to substantiate behavioural findings with evidence of neural changes across different imaging modalities by the Structure Learning training.

An earlier meta-analysis and review indicated that trauma exposure may be related to lower levels of executive functioning in youth. Since different developmental trajectories were found for three core executive functions, the present study focused on working memory, inhibition, and cognitive flexibility specifically. We conducted a multi-level meta-analysis on 55 studies and 322 effect sizes published between 2001 and 2017 that were retrieved from MEDLINE, Embase, and PsycINFO. The 8070 participants in selected studies were aged 2-25 years. We investigated whether the association between constructs would be moderated by trauma-specific moderators (onset, duration, and type), and study (age, gender, ethnicity, and socio-economic status) and measurement (quality) characteristics. We found small to medium effect sizes for working memory (d = −0.49), inhibition (d = −0.46), and cognitive flexibility (d = −0.44). Moderator analyses showed that, for working memory, when studies used low-quality measurements the effect size was significantly stronger than when studies used high-quality measurements.Compared to single trauma-exposed youth, violence-exposed/abused and foster care/adopted youth showed more problems in inhibition, and foster care/adopted youth showed more problems in cognitive flexibility. Our findings imply that trauma-exposed youth have lower levels of executive functions. Clinical practice should incorporate problems in executive functioning, especially working memory, inhibition, and cognitive flexibility, in assessment and treatment guidelines.

Visual-motor illusion (VMI) is an intervention to induce kinesthetic sensation from visual stimuli. We aimed to compare the effects of VMI of different visual stimuli on the paralyzed side ankle joint of stroke hemiplegic patients (hemiplegic patients) and to clarify their indication. We applied two types of VMI images of ankle dorsiflexion: ankle dorsiflexion without resistance (standard VMI (S-VMI)) and maximum effort dorsiflexion with resistance (power VMI (P-VMI)). Twenty-two hemiplegic patients were divided into two groups: Group A, which received S-VMI first and P-VMI one week later (n = 11), and Group B, which received P-VMI first and S-VMI one week later (n = 11). Immediate effects were evaluated. Outcomes were the dorsiflexion angle and angular velocity, degree of sense of agency (SoA), and sense of ownership. Patient’s characteristics of cognitive flexibility were assessed using the Trail making test-B (TMT-B). Fugl-Meyer assessment and the Composite-Spasticity-Scale were also assessed. P-VMI was significantly higher than S-VMI in SoA and dorsiflexion angular velocity. Additionally, the degree of improvement in dorsiflexion function with P-VMI was related to TMT-B and degree of muscle tone. Therefore, P-VMI improves ankle function in hemiplegic patients more than S-VMI but should be performed with cognitive flexibility and degree of muscle tone in mind.

Cognitive flexibility refers to the ability to quickly reconfigure our mind, as when we switch between different tasks. This review highlights recent evidence showing that cognitive flexibility can be conditioned by simple incentives typically known to drive lower-level learning, such as stimulus–response associations. Cognitive flexibility can also become associated with, and triggered by, bottom-up contextual cues in our environment, including subliminal cues. Therefore, we suggest that the control functions that mediate cognitive flexibility are grounded in, and guided by, basic associative-learning mechanisms and abide by the same learning principles as more low-level forms of behavior. Such a learning perspective on cognitive flexibility offers new directions and important implications for further research, theory, and applications.

Background Various instruments have been developed to assess cognitive flexibility, which is an important construct in psychology. Among these, the self-report cognitive flexibility scale (CFS) is particularly popular for use with English speakers; however, there is not yet a Japanese version of this scale. This study reports on the development of a Japanese version of the cognitive flexibility scale (CFS-J), and the assessment of its internal consistency, test–retest reliability, and validities. Methods We used the standard translation–back-translation process to develop the Japanese wording of the items and tested these using a sample of 335 eligible participants who did not have a mental illness, were aged 18 years or older, and lived in the suburbs of Tokyo. Participants included office workers, public servants, and college students; 71.6 % were women and 64.8 % were students. The translated scale’s internal consistency reliability was assessed by calculating Cronbach’s alpha and McDonald’s omega, and test–retest reliability was assessed with 107 eligible participants via intra-class correlation coefficient (ICC) and Spearman’s correlation of coefficient. Exploratory factory analysis (EFA) and correlations with other scales were used to examine the factor-based and concurrent validities of the CFS-J. Results Results indicated that the CFS-J has good internal consistency (Cronbach’s alpha = 0.847, McDonald’s omega = 0.871) and acceptable test–retest reliability (Spearman’s = 0.687, ICC = 0.689). EFA provided evidence that the CFS-J has a one-factor structure and factor loadings were generally appropriate. The total CFS-J score was significantly and positively correlated with the cognitive flexibility inventory-Japanese version and its two subscales, along with the cognitive control scale and the positive subscale of the short Japanese version of the automatic thought questionnaire–revised (ATQ-R); further, it had a significantly negative correlation with the negative subscale of the ATQ-R ( p s < 0.001). This study developed a Japanese version of the cognitive flexibility scale and confirmed its reliability and validity among a sample of people with no current mental illness, who were living in the suburbs of Tokyo.

This research paper discusses the validation process of the cognitive flexibility scale (CFS) as a measurement instrument for farmers’ cognitive flexibility (CF). The role of CF in influencing behaviour has been established for centuries among psychologists. Thus, individual differences might be among the correlates of adoption of cassava processing technology among farmers. However, lack of an effective instrument to measure farmers’ CF has been limiting the predictive and descriptive potential of farmers’ CF. The instrument was validated in a two stages study with some specific objectives guiding the study namely; assess the instrument’s component structure validity and reliability of CFS, examine whether CFS could categorise farmers’ performance in cognitive flexibility by farmers’ demographics; and whether or not could cognitive flexibility have an influence on farmers’ adoption of cassava farming technologies. In the first stage the instrument was pilot tested in a survey conducted in Serengeti district in Mara region of Tanzania among 200 participants. Principle component Analysis (CPA) indicated that CFS was a three factor scale with good internal consistency (α = 0.85). The three factors found were technology acceptance (α = 0.92), open mindedness (α = 0.86), and adapting to new situations (α = 0.37). In the second stage, a total of 360 participants, of whom 181 were males and 178 were females responded to the CFS. It was found that the improved CFS was a three factor scale reaching an internal consistency of α = 0.85. The three subscales in the CFS were adapting to new farming technologies (α = 0.88), acceptance of new farming technologies (α = 0.86), and open mindedness to other people’s ideas (α = 0.80). The findings further indicate low correlations among the subscales, implying discriminant validity of the scale. In addition to theoretical implications, the paper discusses the measure’s effectiveness and its potential applicability in the field of rural development and with specific focus to adoption of farming technologies. The findings provide support for validity and reliability of the CFS and its multidimensional nature. It is recommended that one needs to consider contextual factors such as the level of cassava processing technology before generalizing the validity and reliability of CFS, and thus, a need for further validation studies of the instrument.

Peer feedback affects adolescents' behaviors, cognitions and emotions. We examined neural circuitry underlying adolescents' emotional response to peer feedback using a functional neuroimaging paradigm whereby, 36 adolescents (aged 9-17 years) believed they would interact with unknown peers postscan. Neural activity was expected to vary based on adolescents' perceptions of peers and feedback type. Ventrolateral prefrontal cortex (vlPFC) activity was found when adolescents indicated how they felt following feedback (acceptance or rejection) from peers of low vs high interest. Greater activation in both cortical (e.g. superior temporal gyrus, insula, anterior cingulate) and subcortical (e.g. striatum, thalamus) regions emerged in response to acceptance vs rejection feedback. Response to acceptance also varied by age and gender in similar regions (e.g. superior temporal gyrus, fusiform, insula), with greater age-related increases in activation to acceptance vs rejection for females than males. Affective response to rejection vs acceptance did not yield significantly greater neural activity in any region. vlPFC response suggests cognitive flexibility in reappraising initial perceptions of peers following feedback. Striatal response suggests that acceptance is a potent social reward for adolescents, an interpretation supported by more positive self-reported affective response to acceptance than rejection from high- but not low-interest peers.
