Python 스크립트가 작동하지 않습니까? : 사운드 재생, 반응 시간 측정

Question

참가자가 사운드 파일에서 2/30 사운드를들을 때만 입력 또는 스페이스 바를 얼마나 빨리 눌러야 하는지를 측정하는 스크립트를 만들고 싶습니다. 그래서 사용자는 아무 것도 누르지 않아도되고 스크립트는 계속해서 다음 소리 파일로 이동합니다. 어떻게해야합니까? 내가 지금있는 것은 이것이다 : (대신 사운드 파일, 나는 텍스트 기압 있습니다.) :

# s = sound.Sound('sound.wav') 
# s.play() 

# Register space bar press or mouse click 

# Measure reaction time 

# Check to see if answer is correct to sound - certain sound files are "klik". Others "kast", "løb", "sko" and so on 

# Write csv logfile with coloumns: "ID", "Gender", "Word", "Correct/incorrect", "Reaction time", "Space/click" 

나는 모든 말에 PsychoPy에서 실행됩니다. 친절한 도움을 미리 주셔서 감사합니다.

Answer 1

들여 쓰기에 문제가있어 적절한 수준의 평가판 기능에서 모든 것이 실행되고 있지 않습니다. 응답 처리 여부를보다 직접적으로 확인하기 위해 예외 처리를 생략 할 수 있습니다. 그런 다음 루프가 완료되었지만 키를 누를 경우 발생하는 상황을 처리하기 위해 for 루프에 else: 절을 사용하십시오. 이렇게하면 주어진 프레임에서 발생하는 무응답의 논리를 처리하지 않아도됩니다. 응답이 곧 발생하면 아무 의미가 없습니다. 이 일반 의사와 같은

뭔가 :

# define window 
win = visual.Window(fullscr=True) 

# function to draw instructions (probably overkill unless run more than once) 
def instruct(instructions = 'xxx'): 
    # as you have above 

# function to run each trial 
def trial(number = -999, sound_name = 'A'): 

    sound = Sound.sound(sound_name) 

    if sound_name in ["Klik.wav", "Press.wav", "Throw.wav"]: 
     condition = "press" 
    else: 
     condition = "no_press" 

    event.clearEvents() 

    sound.play() 

    for frame in range(90): 

     time_start = win.flip() 

     keys = event.getKeys(keyList=['space', 'escape'], timeStamped = True)

      key, time_key = keys[0]

좋아는 좋은 - 감사합니다! 이제 스크립트를 계속 개발해 보았습니다. 평가판 목록을 추가했는데 지금은 무엇을해야할지 잘 모릅니다. 내 스크립트는 다음과 같습니다 :
