“…The size of the difference between congruent and incongruent trials in the more-odd shifting task was considered to reflect cognitive flexibility. Previous research has shown that individuals with high cognitive flexibility experience less cost when switching tasks, and thus show less conflict effects in the more-odd shifting task ( Cui et al, 2022 ).…”

Bilingualism has been shown to be associated with creativity, but the mechanisms of this association are not very well understood. One possibility is that the skills that bilinguals use in switching back and forth between languages also promote the cognitive processes associated with creativity. We hypothesized that high-proficient Chinese-English bilinguals would show higher convergent and divergent thinking than low-proficient bilinguals, with the differences being mediated by cognitive inhibition and cognitive flexibility, respectively. Chinese university students (N = 54) were classified as high-proficient (n = 27) and low-proficient (n = 27) bilinguals based on their performance on the National English Test for College Students. As expected, group comparisons showed that the high-proficient group had higher scores on the Remote Associates Test (RAT, convergent thinking) and the Torrance Test of Creative Thinking (TTCT, divergent thinking). Also as expected, the association between bilingualism and convergent thinking was mediated by scores on a Stroop task (cognitive inhibition), and the association between bilingualism and divergent thinking was mediated by scores on a More-odd shifting task (cognitive flexibility). These findings suggest that bilingual learning can promote the development of different components of creativity through stronger cognitive inhibition and cognitive flexibility. The results provide empirical evidence for the relationship and mechanism between bilingual learning and creativity.

“…While the negative effects of sitting on health are apparent, their effects on cognitive performance have been inconsistent. [12] examined the association between sedentary behavior and cognitive exibility in adolescents and found that the association differs according to the type of sedentary behavior. Recreational screen-based sedentary behavior was found to have a negative association with cognitive exibility, while educational (learning) sedentary behavior was found to have a positive association with executive control.…”

Background: This study explored physical activity during remote work, most of which takes place while sitting in front of a computer. The purpose of Experiment 1 was to develop a classification for body motion by creating a neural net that can distinguish among several kinds of chest movement. Experiment 2 examined the effects of chest movements on stress and performance on the Navon test to validate the model developed in Experiment 1. Method and Results: The procedures for this study were as follows. Experiment 1: Creation of the body movement classification model and preliminary experiment for Experiment 2. Data from five participants were used to construct a machine-learning categorization model. The other three participants participated in a pilot study for Experiment 2. Experiment 2: Model validation and confirmation of stress measurement validity. We recruited 34 new participants to test the validity of the model developed in Experiment 1. We asked 10 of the 34 participants to retake the stress measurement since the results of the stress assessment were unreliable. Using LSTM models, we classified six categories of chest movement in Experiment 1: walking, standing up and sitting down, sitting still, rotating, swinging, and rocking. The LSTM models yielded an accuracy rate of 83.8%. Experiment 2 tested the LSTM model and found that Navon task performance correlated with swinging chest movement. Due to the limited reliability of the stress measurement results, we were unable to draw a conclusion regarding the effects of body movements on stress. In terms of cognitive performance, swinging of the chest reduced RT and increased accuracy on the Navon task (β=.015 [-.003,.054], R2=.31). Conclusions: LSTM classification successfully distinguished subtle movements of the chest; however, only swinging was related to cognitive performance. Chest movements reduced the reaction time, improving cognitive performance. However, the stress measurements were not stable; thus, we were unable to draw a clear conclusion about the relationship between body movement and stress. The results indicated that swinging of the chest improved reaction times in the Navon task, while sitting still was not related to cognitive performance or stress. The present article discusses how to collect sensor data and analyze it using machine-learning methods as well as the future applicability of measuring physical activity during remote work.
