Older adults evaluate faces as being more trustworthy than do younger adults. The present work examined whether aging is associated with changes in the dynamic activation of trustworthiness categories toward faces, and if category activation relates to enhanced trust.
Younger and older adults categorized faces as trustworthy or untrustworthy while computer mouse trajectories were recorded to measure dynamic category activation.
Older, but not younger, adults had more dynamic category activation (i.e., trustworthy and untrustworthy) when they viewed untrustworthy versus trustworthy faces. This tendency predicted a bias (pronounced with age) toward evaluating faces as being trustworthy.
A pronounced trust bias in aging may be related to greater dynamic activation of trustworthiness (vs untrustworthiness) when perceiving faces.
老年人对人脸的信任评价高于年轻人。本研究考察了随着年龄的增长,对人脸的信任类别是否会发生动态激活的变化,以及类别激活是否与增强的信任有关。
年轻人和老年人在对人脸进行可信任或不可信任的分类时,记录计算机鼠标轨迹以测量动态类别激活。
与年轻人相比,老年人(而非年轻人)在观看不可信面孔时,会产生更多的动态类别激活(即可信和不可信)。这种趋势预示着(随着年龄的增长)一种将人脸评价为可信的偏见。
在衰老过程中,信任偏见明显,这可能与感知人脸时对可信度(而非不可信度)的动态激活增强有关。
