The investigator proposes to study pictorial priming by using a task previously investigated and published by him. In general, the subject under study will be offered primes in a series of whole pictures and they will be tested using a series of degraded pictures as target items. The subject will receive three identical primes, three similar primes and three pictures that have not been presented during the priming portion of the task. Male and female subjects and the picture feature types contour will be used in the study. The pictures a subject receives during the target series will be either identical in spatial orientation to the prime offered in the first portion of the task or will be a mirror-image in terms of spatial orientation. The subjects performance will be recorded in terms of time to solve the degraded form and the number of keystrokes to solve the degraded form. The investigator hopes to determine if performance is affected by the slowing of the visual system that might occur with aging.

研究者建议通过以下方式研究图形启动： 使用他之前研究并发布的任务。 一般来说，研究对象将被提供启动 在一系列完整的图片中， 一系列退化的图片作为目标项。 受试者 会得到三个相同的素数，三个相似的素数 还有三张照片， 任务的启动部分。 男性和女性受试者， 研究中将使用图像特征类型轮廓。 拍摄对象在目标系列中接收到的图片 将在空间方向上与 在任务的第一部分中提供的主要或将是一个 在空间方向上的镜像。 受试者 性能将被记录在时间方面，以解决 退化的形式和解决问题所需的时间 退化形式。 调查人员希望确定， 表现受到视觉系统变慢的影响 这可能会随着年龄的增长而发生。
