Question

我在Psychopy上创建了一个任务，其中从罐子中抽出珠子。绘制50个不同的珠子，并且在每个珠子之后，要求参与者进行概率评级。该任务从excel文件循环，但是需要很长时间才能完成50个评级。我希望得到前10个珠子的评级。然后为第二个珠子绘制一个等级，直到绘制出20个珠子。然后对于接下来的30个珠子，直到第50个珠子只要求每五个珠子的评级（我真的很新编码，抱歉这可能提前有多么不正确）。我写过这样的代码然而不幸的是它不起作用？（在没有评级的转弯处，我试图用键盘响应来触发序列中的下一个事物出现） -

for row_index, row in (beads_params_pinkbluegreyratingparamters.xlsx):
if row(0:10) and t >= 0.0 and rating.status == NOT_STARTED:
    break
    rating.tStart = t  # underestimates by a little under one frame
    rating.frameNStart = frameN  # exact frame index
    rating.setAutoDraw(True)
 continueRoutine &= rating.noResponse # a response ends the trial

elif row(12:20:2) and t >= 0.0 and rating.status == NOT_STARTED:
    break
    rating.tStart = t  # underestimates by a little under one frame
    rating.frameNStart = frameN  # exact frame index
    rating.setAutoDraw(True)
continueRoutine &= rating.noResponse

 elif rows.event.getkeys, row(11:19:2):
     elif len(theseKeys) > 0:
        break 
        key_resp_2.keys = theseKeys [-1]
        key_resp_2.rt = key_resp_2.clock.getTime()
     continueRoutine = False
 elif row(20:50:5) and t >= 0.0 and rating.status == NOT_STARTED:
    break
    rating.tStart = t  # underestimates by a little under one frame
    rating.frameNStart = frameN  # exact frame index
    rating.setAutoDraw(True)
continueRoutine &= rating.noResponse
       rows.event.getKeys, row[21, 22, 23, 24, 26, 27, 28, 29, 31, 32, 33, 34, 36, 37, 38 ,39, 41, 42, 43, 44, 46, 47, 48, 49]:
        elif len(theseKeys) > 0:
            key_resp_2.Keys = theseKeys [-1]
            key_resp_2.rt = key_resp_2.clock.getTtime()
         continueRoutine = False

你应该只循环一次，但是在一个循环中执行所有检查：

for row_index, rows in (beads_params_pinkbluegreyratingparamters.xlsx):
    if (row_index < 10):
        rows.ratingscale(0:10)
    elif (row_index >=10 and row_index <20):
        rows.ratingscale(12:20:2)
        rows.key_resp_2(11:19:2)
    elif (row_index >=20):
        rows.ratingscale(25:50:5)
        rows.key_resp_2[21, 22, 23, 24, 26, 27, 28, 29, 31, 32, 33, 34, 36, 37, 38, 39, 41, 42, 43, 44, 46, 47, 48, 49]

请注意，代码中存在一些语法错误，例如： rows.key_resp_2(11:19:2)没有意义。

我想在循环中的不同点触发响应
