Attentional capture by evaluative stimuli: gain- and loss-connoting colors boost the additional-singleton effect.

摘要: In a valence induction task, one color acquired positive by indicating the chance to win money (in case of fast and correct responses), different negative danger lose slow or incorrect responses). additional-singleton trials visual search task-irrelevant singleton was either one, two neutral colors. We found an effect (i.e., longer RTs with than in no-singleton control condition). This significantly increased for valent colors (with no differences between them) relative them, either). result favors hypothesis that general relevance stimuli elicits attentional capture, rather negativity bias hypothesis.
