| Research Abstract |
Two experiments examined aging effects in disengagement of attention from face stimuli. In Experiment 1, ten undergraduate students and 13 older people (M=68.8) were first presented a normal human face stimulus in the center of the monitor screen. Then the face stimulus was removed and replaced by presenting a target on the right or left side of the screen. As soon as they detected the target, the participants were to press the keyboard button on the same side of the screen as the target. Four different time intervals were used in order to investigate the facilitation effects of the disengagement of attention. In Experiment 2, the same participants as Exp. 1 were exposed to one of three facial expressions (neutral, happy, or anger) and told to press the keyboard button in the same manner as Exp. 1 when the target appeared. In Exp. 1, older people tended to react faster to the face stimulus disengagement than the other stimulus. In Exp. 2, the two age groups showed no different reaction to the three facial expressions.
