Journal Notes on Sleep Deprivation

Tucker et al (2010) Effects of eternal rest want on dissociated components of executive expire. The authors were looking to investigate to what extent executive functions are impaired by sleep loss. Method: 23 pps, change integrity in to one crowd (SD) that mazed 62 hours of sleep and a control group (normal sleep). The SD group had two recuperation nights of sleep. Both groups of pps were campaigned with 3 tests @ baseline, 51 hours of sleep dep, and once more after the 2 nights of convalescence sleep. The executive function tests were: 1.A modified Sternberg test (you see a list of items and therefore come in a analyze item and asked is this part of the professional localise? pps have to process as quickly as possible). The test was modified so that 50% of the probe items were include in the original set and 50% were not. 2.Probed recall caper (a test to measure metro to proactive interference). 3.Phonemic verbal articulateness task (how m any talking to start with A?). This is a good test for mensuration cognitive flexibleness and mental set shifting. They also had to do a outpouring of non-executive function tests to check how their alertness levels (tests include the Psychomotor care Tests). Results: Performance in the modified Sternberg test did significantly decay in the SD group.

And so did the performance of the non-executive function test. Performance in the probed recall test and verbal suavity was not abnormal (actually it even improved slightly in verbal fluency!). Suggests: The decline in the Sternberg test, except not i n the otherwise executive function test, wa! s mediated by the decline in alertness and vigilance as displayed by performance in non-executive tests. So sleep deprivation has an effect, but not outright in executive functioning, however executive functioning is indirectly affected by deterioration in non-executive parts of the brain. pedestrian and Stickgold (2010) Overnight alchemy: sleep-dependent memory evolution.
