Subclaims¶

q3 i? Objects trained with in-depth functional stories show facilitated recognition when blurred and an attenuated P100 component; faces trained with in-depth semantic knowledge likewise elicit reduced P100. → Collins 2014

Evidence¶

Collins 2014¶

Collins, Jessica A., & Olson, Ingrid R. (2014). Knowledge is Power: How Conceptual Knowledge Transforms Visual Cognition. Psychonomic bulletin & review. https://doi.org/10.3758/s13423-013-0564-3

The review describes Abdel-Rahman and Sommer's two-part ERP training paradigm in which conditions were matched for naming, visual exposure, and verbal information amount, differing only in whether the verbal information was informative. No effect sizes are printed.

"The in-depth stories facilitated recognition when these objects were blurred in an identification task, and this effect was associated with an attenuated P100 component."
