The main aim of this study was to investigate the effects on performance and workload of the shifting between levels of automation: from manual to automatic (forward shift) and from automatic to manual (backward shift). Three levels of difficulty of the Tetris game were implemented as task load conditions. Two versions of the game were also implemented: automated and manual. The automated version provided the participants a projection of the falling block on the lowest layer for making its placement easier. Results showed that the commonsense consideration that only shifts toward a lower level of automation should reflect poor performance and higher workload is unsupported. Forward shifts may affect performance as well, particularly when workload is moderate.

Abstract
The main aim of this study was to investigate the effects on performance and workload of the shifting between levels of automation: from manual to automatic (forward shift) and from automatic to manual (backward shift). Three levels of difficulty of the Tetris game were implemented as task load conditions. Two versions of the game were also implemented: automated and manual. The automated version provided the participants a projection of the falling block on the lowest layer for making its placement easier. Results showed that the commonsense consideration that only shifts toward a lower level of automation should reflect poor performance and higher workload is unsupported. Forward shifts may affect performance as well, particularly when workload is moderate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
