我几乎是'建设者'用户。
我通过修改“demo IAT practical-Creative”来制作IAT 但我发现演示IAT与哈佛IAT和另一种IAT在反馈方面有所不同。 演示IAT：反馈“X”出现，如果出现，则允许的键都是“e”和“i”。如果参与者第二次出错，则例程结束并继续。 哈佛和其他IAT：出现反馈“X”，如果出现，则允许的键只是“正确”键。如果参与者再次犯错，他或她无法结束审判，并且“X”出现，直到参与者按下正确的密钥。
我试图将demoIAT修改为像哈佛和其他IAT一样。
我做了 [允许的密钥] =＆gt; $ [key]（设置每次重复）虽然有效，但实际上，问题发生在下一次试验中。 有时，如果参与者连续按错了答案，但最后按正确答案， 下一次试验的刺激出现“带X”......反馈X ..
我不知道它是之前试验的剩余部分.. 喜欢时间分辨率的问题..
当参与者连续按下按钮时，心理模糊通常会出现问题 不必要的巨大时间？我将保留代码版本.. 我会留下一个常规块.. 这与demoIAT几乎相同，只是它在“Keys_1”响应中只有一个“允许键”。
