Priority of the "self" is thought to be evolutionarily advantageous. However, evidence for this priority has been sparse. In this study, subjects performed a gender categorization task on self- and non-self target faces preceded by either congruent (same gender as target) or incongruent (different gender) periliminal (33ms) or subliminal (17ms) primes. We found that subliminal primes induced a priming effect only on self target faces. This discovery of a self-specific priming effect suggests that functional specificity for faces may include timing as well as spatial adaptations.
“自我”优先被认为在进化上是有利的。然而,支持这种优先的证据一直很少。在这项研究中,被试在自我和非自我目标面孔之前进行性别分类任务,这些面孔之前分别呈现一致(与目标性别相同)或不一致(与目标性别不同)的阈下(33ms)或阈上(17ms)启动。我们发现,只有在自我目标面孔上,阈下启动才会引起启动效应。这一自我特定的启动效应的发现表明,面孔的功能特异性可能包括时间和空间适应。
