In a new study published in Journal of Experimental Psychology: Learning, Memory, and Cognition, Sørensen et al. (2014) investigate the effects of temporal expectation and how it modulate attentional TVA parameters. They demonstrate that the temporal expectancy paradigm modulate visual short-term memory, possibly through a phasic modulation of observer arousal akin to a hypothesis proposed by Easterbrook (1959). Sørensen et al. also present a novel analysis using the standard deviation of the attentional weights as a measure of how evenly an observer distribute their attentional resources. Hereby, it is possible to measure the scope of attentional focus in addition to the traditional TVA parameters.
