A recent study published online in PLoS ONE by Ásgeirsson et al. (2015) use TVA to analyse what attentional components are modulated by stimulus congruency in colour-grapheme synaesthesia. The authors report that processing speed is affected by stimulus congruency. Surprisingly, several TVA parameters such as the threshold for visual perception as well as attentional selectivity remain un affected by a manipulation of congruency. The authors argue that as well as yielding a more detailed understanding of how synaesthesia interact with cognitive components like attention.

A new study by Sørensen and Kyllingsbæk (2012) demonstrate an effect of expertise on visual short-term memory (VSTM) capacity. The study measured the change in VSTM capacity for letters and pictures in four age groups. Here an increase in VSTM capacity for letters with age but not for pictures is reported. The results indicate that VSTM capacity is dependent on the level of expertise for specific types of stimuli processed.
