SNARC效应（spatial-numerical association of response codes）是指处理数字可以调节反应时间的发现，低数字促进左反应，高数字促进右反应。最近的证据表明，这种影响的轨迹是在反应选择阶段。为了检验这种可能性，我们向参与者展示了低或高的数字，然后要求他们按下两个键（左或右）中的一个-他们觉得更舒服的那个。结果表明，低数字偏向选择左按键，而高数字偏向选择右按键。因此，SNARC效应不仅影响可以启动多快的响应，还影响将选择什么响应。(c)Elsevier Masson Srl. All rights reserved.
The SNARC (spatial-numerical association of response codes) effect refers to the finding that processing digits can modulate response times, with low digits facilitating left responses and high digits facilitating right responses. Recent evidence indicates that the locus of this effect is in the response selection stage. To examine this possibility, we presented participants with low or high digits and then asked them to make one of two key-presses (left or right) - whichever one they felt more comfortable making. The results showed that low digits biased the selection of left keypresses while high digits biased the selection of right keypresses. Thus, the SNARC effect not only affects how fast responses can be initiated but also affects what responses will be selected. (c) 2007 Elsevier Masson Srl. All rights reserved.
