不靠譜PsychoPy入門教程目錄：
幫師妹做的程序筐乳，雖然最后沒有采用叨恨∮嗬瑁可能用這個(gè)做動(dòng)畫還是有點(diǎn)兒吃力溜嗜，在我的電腦上可以妥妥的跑起來艇棕，放師妹的電腦上就各種卡 o(╯□╰)o
不管啦。實(shí)驗(yàn)要求是：
- 在屏幕上某個(gè)范圍內(nèi)搞出n個(gè)白色的小圓巩检，其中四個(gè)是追蹤目標(biāo)元咙。小圓出現(xiàn)的位置是隨機(jī)的。
- 靜止呈現(xiàn)一秒鐘湃密。4個(gè)追蹤目標(biāo)上有小紅點(diǎn)兒做提示诅挑。
- 然后這些球就開始動(dòng)了。運(yùn)動(dòng)方向是隨機(jī)的泛源，每隔一秒轉(zhuǎn)換一次方向拔妥。
程序?qū)懲曛筮\(yùn)行起來是這樣的：
被試的任務(wù)就是盯著那幾個(gè)追蹤目標(biāo)，然后在運(yùn)動(dòng)結(jié)束之后达箍，選出四個(gè)目標(biāo)來没龙。選擇部分就要用到一下鼠標(biāo)。還有設(shè)置什么誘導(dǎo)刺激幻梯，就是在運(yùn)動(dòng)過程中兜畸，某個(gè)小圓會(huì)搞小動(dòng)作，看被試能不能注意到碘梢。有興趣的同學(xué)可以試試玩兒咬摇。
