python-3.x - Dual Task 中的同时响应收集

Question

我正在尝试执行双重任务。这两个任务都要求判断一个数字。刺激以可变的间隔（a_soa）一个接一个地出现。我需要收集对键盘上给出的刺激的反应时间（第一个任务：y 或 x 键；第二个任务：或 . 键）。我目前正在努力实现这一点，因为对于第一个任务，程序需要在第二个任务甚至绘制之前开始等待响应。然后第二个刺激出现并标志着对第二个任务的可能反应的开始。

我正在使用的两个函数和主要函数的代码都包含在下面。

def StimPresent(a_soa, b_s1, c_s2):
    """
    Function StimPresent(a, b, c) presents stimulus_1 (b) for SOA ((a) number of frames),
    then it adds stimulus_2 (d) and shows both for max 60 frames
    and returns time of stimulus onset (tim)
    """
    if event.getKeys(keyList='escape'):
        myWin.close()
        core.quit()

    for frameN in range(a_soa):
        b_s1.draw() 
        fixation.draw()

        if frameN == 0:                     # RT S1 starting immediately after flip
            onsetS1 = RT1.getTime()  
        myWin.flip()

    for frameN in range(a_soa, (a_soa+60)):

Answer 1

非常感谢，您的评论帮助了我！我用键盘类重写了代码，但现在我遇到了另一个问题：该函数只返回 666 作为 buttonR1Code 和 buttonR2Code。仅当收集到现在的响应时才应提供这些信息。我怎样才能解决这个问题？有什么建议么？
