In two experiments, the contributions of memory and attention processes to the cognitive abilities of reasoning and perceptual speed were investigated. Two measures of speed of information retrieval from long-term and short-term memory (Posner paradigm, Sternberg paradigm) and two attention measures (continuous attention test, attention switching test) were(More)
The research work reported in this paper addresses the question whether retest practice changes the speed-ability relationship. In three successive test sessions several cognitive tests of attention, memory and working memory were substantial decreases of mean reaction time in the memory and working memory tasks while in attention tasks the effect was small(More)
Relationships between the time series of five physiological sleep parameters were examined and related to sleep quality. Twenty-eight male coronary patients participated in the investigation. Recordings were carried out with a mobile device consisting of two Medilog 4-24 recorders and one DMI-recorder assessing five biosignals: EEG, EOG, EMG, ECG and body(More)
