Abstract
Three groups of four subjects were exposed to 64-hours of sleep deprivation. Collective task performance, group dynamics, cognitive abilities and subjective well-being were assessed over 11 15-min long sessions during which each group had to solve a syllogism. The speed of problem solving did not change systematically as a function of sleep-deprivation. However, subjects did not contribute equally to the solution of syllogism. Behavioural observations revealed that within each group one or two subjects rotated leadership roles in verbal task solving. Neither individual cognitive abilities nor individual states of well-being were systematically related to the allocation of individual task solving efforts. Regarding group interactions, intra-group hostility remained low and the group atmosphere was positive throughout the experiment. TRUNCATED
