呈现图片

准备一张图片和一个python文件，如下图：

python文件中写如下代码：

# -*- coding: utf-8 -*-
"""
Created on Tue Apr 12 10:31:15 2016@author: zbg
"""from psychopy.visual import Window, ImageStim, TextStim
from psychopy import core, event, gui
import randomname='1.png'
win = Window()
stim = ImageStim(win, name)
stim.draw()
texture = TextStim(win, text = u'按空格键退出', pos = [0,30], units = 'pix')
texture.draw()
win.flip()while 'space' not in event.getKeys():pass
win.close()

运行后可以呈现图片

量表评分

编写如下程序可以实现量表评分

# -*- coding: utf-8 -*-
"""

"""from psychopy.visual import Window, ImageStim, TextStim
from psychopy import core, event, gui
import randomscales = [('Meaningful1', u"我能理解这幅画的意义"),('Meaningful2', u"我能理解这幅画的主题"),('Unity',       u"这幅画的构图是和谐统一的"),('Complexity',  u"这幅画的构图是复杂的"),('Variety',     u"这幅画构图是多样的"),('Liking',      u"我喜欢这幅画"),('Pleasing',    u"这幅画使我感到愉悦"),('Interesting', u"这幅画能引起我的兴趣。"),]def ShowScale(text):def GetMyKey():event.clearEvents1('all')keys=[]while True:while len(keys) == 0:core.wait(0.1)keys=event.getKeys()if keys[0] in ['1', '2', '3', '4', '5', '6', '7']:return keys[0]keys = []t =TextStim(win, text ,pos=(0,-0.0))t.draw()t =TextStim(win, u'1不同意------------------------------7非常同意',pos=(0,-50), units = 'pix')t.draw()win.flip()key = GetMyKey()t =TextStim(win, u'你按下了' + key,pos=(0,-0.2),color = (0 ,1.,0))#反馈t.draw()win.flip()core.wait(0.5)return keywin = Window()result = {}
for label, text in scales:key = ShowScale(text)result[label] = key #把结果储存到字典里，后继可以保存到文件里。win.close()
print result

把两个程序合在一起可以实现呈现图片，然后用量表评分，这里不做赘述。

psychopy自带的量表工具

你也可以使用psychopy自带的量表工具，它支持鼠标选择或者按键数字选择，用回车键确认或者鼠标点击方框确认。以下是示例代码与运行截图：

# -*- coding: utf-8 -*-
"""
Created on Tue Apr 12 10:31:15 2016@author: zbg
"""
from psychopy import visual,eventwin = visual.Window()
rating = visual.RatingScale(win=win, name='rating', marker=u'triangle',
size=1.5, pos=[0.0, -0.4], low=1, high=7, labels=[u'不同意', u'中立', u'完全同意'],
scale=u'你多大程度上赞同希拉里当选美国总统？')
#item = <statement, question, image, movie, ...>
while rating.noResponse:#item.draw()rating.draw()win.flip()visual.TextStim(win, text = u"选了%d用了%.3f秒\n按空格退出" % (rating.getRating(), rating.getRT())).draw()
win.flip()while 'space' not in event.getKeys():passprint  rating.getRating()
print  rating.getRT()
print  rating.getHistory()
