Exogenous and endogenous attention during perceptual learning differentially affect post-training target thresholds.

abstract：:It has been shown previously that liking and valence of associations in response to artworks show greater convergence across viewers for representational than for abstract artwork. The current research explored whether the same applies to the semantic content of the associations. We used data gained with an adapted un...
