Sedentary behaviour is increasing and has been identified as a potential significant health risk, particularly for desk-based employees. The development of sit-stand workstations in the workplace is one approach to reduce sedentary behaviour. However, there is uncertainty about the effects of sit-stand workstations on cognitive functioning. A sample of 36 university staff participated in a within-subjects randomised control trial examining the effect of sitting vs. standing for one hour per day for five consecutive days on attention, information processing speed, short-term memory, working memory and task efficiency. The results of the study showed no statistically significant difference in cognitive performance or work efficiency between the sitting and standing conditions, with all effect sizes being small to very small (all ds < .2). This result suggests that the use of sit-stand workstations is not associated with a reduction in cognitive performance. Practitioner Summary: Although it has been reported that the use of sit-stand desks may help offset adverse health effects of prolonged sitting, there is scant evidence about changes in productivity. This randomised control study showed that there was no difference between sitting and standing for one hour on cognitive function or task efficiency in university staff.

These results indicate that cognitive performance is not degraded with short-term use of alternate workstations.

This study investigated the relationship between adolescent self-esteem and maternal parenting style, using the four-style typology identified by Maccoby and Martin (1983). Additionally, the researchers considered whether it was more pragmatic to conceptualise parenting style as two separate co-occurring dimensions of parenting: responsiveness and demandingness. Male and female adolescents (N = 140, mean age 14.73 years, 64% female) completed questionnaires measuring perceived maternal responsiveness and demandingness, and self-esteem. Consistent with previous research, differences were found between the four parenting styles for adolescent self-esteem. However, maternal responsiveness was demonstrated to be the only significant predictor of adolescent self-esteem (p < .001). The researchers concluded that considering responsiveness and demandingness as separate dimensions, rather than combining them to form discrete categories, provided a more accurate and practical conceptualisation of the relationship between maternal parenting style and adolescent self-esteem.
