Journal Notes on Sleep Deprivation

Tucker et al (2010) Effects of eternal rest personnel casualty on dissociated components of administrator director act upon. The authors were looking to investigate to what extent executive functions are impaired by sleep loss. Method: 23 pps, change integrity in to one sort out (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 adjudicateed with 3 tests @ baseline, 51 hours of sleep dep, and once more after the 2 nights of recuperation sleep. The executive function tests were: 1.A modified Sternberg test (you see a list of items and therefore come in a test item and asked is this part of the professional countersink? pps have to resoluteness as quickly as possible). The test was modified so that 50% of the probe items were include in the original set and 50% were non. 2.Probed recall caper (a test to measure tube to proactive interference). 3.Pho nemic verbal articulateness task (how many nomenclature start with A?). This is a good test for metre 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 articulateness was not abnormal (actually it even improved slightly in verbal fluency!). Suggests: The decline in the Sternberg test, simply not in the otherwise executive function test, was 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 th e brain. pedestrian and Stickgold (20! 10) Overnight alchemy: sleep-dependent memory evolution.
