Question

我对心理学很陌生，但到目前为止，我在录制键盘事件方面遇到了很多麻烦。键盘演示工作，所以我知道它是可能的，但是当我在我自己的程序中实现代码时，它根本不记录任何键盘活动。现在我的程序非常简单，因为我只是试图掌握它。我有一张照片，想要在照片在屏幕上显示时记录按键的持续时间。我有几个打印声明作为健全性检查，当我运行它（并使用键盘）时，它不打印任何东西。这是我的代码大纲：

from psychopy.iohub import launchHubServer, EventConstants

io = launchHubServer()
keyboard = io.devices.keyboard
keyboard.reporting = True

#-------Start Routine "trial"-------
continueRoutine = True
io.clearEvents('all')
duration_lst=[]
while continueRoutine and routineTimer.getTime() > 0:
   # get current time
   t = trialClock.getTime()
   frameN = frameN + 1  # number of completed frames (so 0 is the first frame)
   # update/draw components on each frame

   # *image* updates
   if t >= 0.0 and image.status == NOT_STARTED:
      # keep track of start time/frame for later
      image.tStart = t  # underestimates by a little under one frame
      image.frameNStart = frameN  # exact frame index
      image.setAutoDraw(True)
   if image.status == STARTED and t >= (0.0 + (5.0-    win.monitorFramePeriod*0.75)): #most of one frame period left
    image.setAutoDraw(False)
    # *ISI* period
    if t >= 0.0 and ISI.status == NOT_STARTED:
       # keep track of start time/frame for later
       ISI.tStart = t  # underestimates by a little under one frame
       ISI.frameNStart = frameN  # exact frame index
       ISI.start(0.5)
    elif ISI.status == STARTED: #one frame should pass before updating params and completing
        ISI.complete() #finish the static period
    # get keyboard events
    for event in keyboard.getEvents():
        print event
        if event.type == EventConstants.KEYBOARD_CHAR:
             key_press_duration=event.duration
             duration_lst.append(key_press_duration)
             print duration_lst

    # check if all components have finished
    if not continueRoutine:  # a component has requested a forced-end of Routine
    break
    continueRoutine = False  # will revert to True if at least one component still running
    for thisComponent in trialComponents:
        if hasattr(thisComponent, "status") and thisComponent.status != FINISHED:
            continueRoutine = True
            break  # at least one component has not yet finished

    # check for quit (the Esc key)
    if endExpNow or event.getKeys(keyList=["escape"]):
        core.quit()

    # refresh the screen
    if continueRoutine:  # don't flip if this routine is over or we'll get a blank screen
        win.flip()

我尝试在这里剥离所有不必要的东西（变量，窗口，刺激等）并使用keyboard.getReleases()所以归结为：

from psychopy import iohub
io = iohub.launchHubServer()
keyboard = io.devices.keyboard
print 'press something now!'
while True:
    # get keyboard releases
    for event in keyboard.getReleases():
        print 'Released!'

这应该在控制台中打印有关每个密钥版本的所有信息。它至少对我有用。如果它也适合您，则问题可能与您脚本中的其他内容有关。
