本文采用“负启动”范式，通过三个实验考察了正常被试的认知差异。Stroop颜色词的列表在不同的显示时间在一些启动和非启动条件，其中一个被忽略的颜色名称预测的颜色下一个目标项目。在根据新的遗传型量表（STA）选择的高遗传型受试者中，通常在这种情况下发现的增加的RT降低，甚至逆转。这种效果仅限于一个非常短的演示时间（100毫秒），这表明，autootypy与削弱抑制操作的早期（自动）阶段的信息处理。熟悉的Stroop（干扰）效应总体上与负启动有关，但不负责shizotypy差异。
Three experiments are reported using the ''negative priming'' paradigm to investigate cognitive differences in normal schizotypal subjects. Lists of Stroop colour words were presented at different display times in a number of priming and non-priming conditions, in one of which the ignored colour name predicted the colour of the next target item. The increased RT latencies to the target normally found in this condition were reduced, or even reversed, in high schizotypal subjects selected on the basis of a new schizotypy scale (STA). This effect was confined to a very short presentation time (100 ms), suggesting that schizotypy is associated with weakened inhibition operating in the early (automatic) stages of information processing. The familiar Stroop (interference) effect was related overall to negative priming, but was not responsible for the shizotypy differences.
