EFFECTS OF TRANSVERSE ACCELERATION ON PERFORM ANCE OF TWO RUNNING MATCHING MEMORY (RMM) TASKS,
Abstract
The present investigations were undertaken to study the nature of degredation in higher mental functioning which might be produced by exposure of man to transverse G. A running matching memory (RMM) task was selected to study the higher mental functioning. This task involved sequential comparisons of same or different for a present symbol with a symbol occurring at a fixed interval (1-back, 2-back, 3-back, etc.) before the viewed symbol. The first experiment on the centrifuge included 2-back, 3-back and 4-back RMM conditions with a 5-sec interval to perform the memory match. All runs were at 5 G, and all series were 50 symbols in length. Each sub ject had 5 consecutive series consisting of a pre-test static series, three consecutive dynamic series, and a post-test static series. There were 7 Ss per condition. Results showed task improvement from pre- to post-test over the cof the dynamic runs. However, means (per cent correct) for all series were lower than for control groups performing five consecu tive static series away from the centrifuge setting. (Author)
