Guided by Basic Psychological Need Theory, we investigated the combined associations between need satisfaction and need frustration and their relations with theoretically relevant correlates including mindfulness, physical literacy, physical activity enjoyment, and physical activity. The participants were Singapore-based school students who completed a cross-sectional survey. The results of the latent profile analysis identified four distinct need profiles: profile 1–average satisfaction and frustration ; profile 2–low satisfaction, above average frustration; profile 3–very high satisfaction, very low frustration ; and profile 4–high satisfaction, (...) very high frustration. Among these, profile 3 was the most adaptive one; it had the highest levels of mindfulness, physical literacy, physical activity enjoyment, and moderate-to-vigorous physical activity. Experiences of need satisfaction countered the negative effects of need frustration on these correlates. These findings enhance our understanding of students’ psychological need experiences and highlight the need for investigating the combined associations between need satisfaction and need frustration.

Non-striving is an important aspect of mindfulness practice, but it has not been sufficiently researched. This study examine whether a strange loop based task — Infinite Water Scooping Task — performed for ten minutes, has an effect on non-striving behaviour and performance in a subsequent word length comparison task. Results showed that performance (number of correct trials) did not differ significantly between the two groups, though the experimental group tended to perform worse. However, participants in the experimental group took a (...) significantly shorter time to respond to the word length comparison task than those in the control group. It is inferred that shorter time taken reflects response without investing much effort to count with care, i.e. non-striving. The present study demonstrates that the brief strange loop task implemented in this study elicited non-striving behaviour compared to the effects of the control task and adds to the understanding of non-striving in the context of mindfulness. The Infinite Water Scooping Task may be useful for illustrating and teaching non-striving within mindfulness practice. (shrink)
