摘要: 为评价自闭特质个体生物运动信息感知能力,采用自闭特质问卷(AQ)筛查出自闭特质组和对照组各35人,进行时距判断任务的生物运动信息感知能力测试。结果表明,在包含社会性线索的完整生物运动序列实验中,对照组主观相等点(PSE)值为-0.095±0.336,自闭特质组PSE值为0.104±0.252,两组PSE值差异有统计学意义(t=-2.796,P<0.05)。自闭特质组PSE值为正值,与“0”比较差异有统计学意义(t=2.434,P<0.05),即具有时距压缩效应。在去除社会性线索的杂乱生物运动序列实验中:对照组PSE值为-0.079±0.250,自闭特质组PSE值为-0.083±0.306,两组之间PSE值差异无统计学意义(t=0.061,P=0.951)。自闭特质个体对完整生物运动信息感知存在缺陷,表明自闭特质影响个体对于完整生物运动信息的加工。

Abstract: To explore biological motion perception in individuals with autistic traits, we screened 35 individuals with high autistic traits by AQ as autistic traits (AT) group. Another 35 individuals with low autistic traits were included as controls. All subjects took the time lag judgment task to test their abilities of biological motion perception. As results, in biological motion task with social cues, there was a significant difference between the control group and AT group (-0.095±0.336 vs 0.104±0.252, t=-2.796, P<0.05) regarding the PSE values. The PSE value of the AT group was positive. Compared with "0", the difference was statistically significant (t=2.434, P<0.05), which means a "time distance" compression effect. In biological motion task without social cues, there was no significant difference between control group and AT group (-0.079±0.250 vs -0.083±0.306, t=0.061, P=0.951) regarding the PSE values. In conclusion, the individuals with high AT have deficit in perceiving biological motion with social cues. These results implicate that autistic traits can affect the ability to perceive biological motion.
