ATTENTION AND PERCEPTION

Störmer et al. (2009). Cross-modal cueing of attention alters appearance and early cortical processing of visual stimuli. PNAS, 106, 22456.

An enduring question in the attention literature is whether visual attention can affect the perception of an object. Some results support the idea that attention does alter perception; for example, when participants attend to a low-contrast grating (a Gabor patch), that grating is reported as having a higher contrast than an unattended comparison grating (Carrasco et al., 2004, Nat Neurosci 7:308). However, other findings indicate that attention influences later, decisional processes and that altered perception of grating stimuli might be caused by sensory interactions, not attention (e.g., Schneider, 2006, P&P 68:800).

Against this theoretical landscape, Störmer et al. make at least two important contributions to our understanding of attentional effects. First, they presented cues and targets in different sensory modalities to avoid potential sensory interactions. Attention was cued to a location with an auditory tone, followed by visual targets. Second, in addition to measuring overt behavioral responses to visual stimuli, Störmer et al. …
