When you fail to see what you were told to look for: Inattentional blindness and task instructions

Inattentional blindness studies have shown that an unexpected object may go unnoticed if it does not share the property specified in the task instructions. Our aim was to demonstrate that observers develop an attentional set for a property not specified in the task instructions if it allows easier performance of the primary task. Three experiments were conducted using a dynamic selective-looking paradigm. Stimuli comprised four black squares and four white diamonds, so that shape and colour varied together. Task instructions specified shape but observers developed an attentional set for colour, because we made the black–white discrimination easier than the square–diamond discrimination. None of the observers instructed to count bounces by squares reported an unexpected white square, whereas two-thirds of observers instructed to count bounces by diamonds did report the white square. When attentional set departs from task instructions, you may fail to see what you were told to look for.     

Socio-Economic Status,Time Spending,and Sleep Duration in Indian Children and Adolescents

In this article physical activity, screen time, and academic work are studied as mediators between socio-economic status and sleep duration among school children in India. Participants were 268 school children aged 10–15 from Pune, India. They were sampled from private schools and impoverished public schools. We found that the highest socio-economic status children reported almost an hour and a half less sleep than their lowest socio-economic status counterparts. The lower socio-economic status children reported more physical activity and screen time, and the higher socio-economic status children reported spending more time on academic work. Although screen time was negatively related to sleep duration, academic work was the strongest mediator between socio-economic status and sleep duration. Physical activity was not a significant mediator. In India, academic work is a strong predictor of a lower sleep duration among children and adolescents.

Group climate and group development in a community meeting on a short-term inpatient psychiatric unit

Group climate and group development of the community meeting on a short-term inpatient psychiatric unit are examined. The Group Climate Questionnaire (GCQ) was administered to all staff and patients present at the weekly community meeting on an acute treatment unit in a teaching hospital over a 12-week period. Results show that staff and patients perceive the community meetings in relatively similar ways, that the group climate of a community meeting can attain a positive working state, and that, at times, the meeting can progress through developmental stages of group process. Behavioral observations support the GCQ as a measure of group interaction.The authors gratefully acknowledge the assistance of Mary Pat Donnelly with the statistical analyses and the cooperation of all staff and patients who participated in this study.
