| Development of lying-behavior is a very important process in children's socialization. Most studies on the development of lying focused on children's lying-cognition and development of lying-behavior. There is little study on the development of lying-behavior for blind up to now. The present study examined the development of lying-behavior and lying-ability and actors that influence lying for the blind without sight .We tried to find some facial expression characters of lying for the blind.Our research was maily carried out by three experiment series. In study 1, we take the behaviors temptation resistance paradigm which adapt to the blind. We also observed blind's lying-behaviors after occurrence of their touching and found factors that influence lying. In study2, College students observed videotaped interviews of the blind either lying or telling the truth about committing a misdeed of touching the toy. We want to know the lying ability of blind .In study2, we used some coding system to analyze the facial expression movements, then compared the frequency which produced by the blind when lying or truth telling.The following results were obtained:(1)In temptation resistance paradigm,35% of the blind committed a misdeed of touching .With increase of the age under 18 years old, the percent of touching decreased .The blind 's committing a misdeed has related to the learning achievement, the blind which study bad inclined to touching(2) Among the blind that touched, there are 71.4 percent people lying to experimenters on their out-of-line behavior, There was a significant aged difference in terms of the proportion of the children who told lie. The proportion of 16 years olds is larger than10-15 years old and the group of 6-10 years old.(3) 6 -year-old blind can adopt strategies in their lying-behavior. Among the people who lied, 55.6 percent could adopt strategies. They could use the strategies better with the age increased(4) The college students have no ability to detect blind people's deception. On average, accuracy rate for college students to detect the blind deception was 49.6%. This rate is below the chance rate of 50%. There are also no differences between the congenital blind and the adventitious blind.(5)The facial expressions of the blind that lied or told truth were rather similar. Significant difference between the lie-teller and nonliar emerged in the expression of eyes down. Compared with the lie teller, brow tight, and nose wrinkle were more frequency in the blind who touched that told truth. Significant difference between the congenital blind and adventitious blind that lied emerged in the expression of lip corner pull.(6) Whether lying or truth-telling, there were no differences of the siglatent period before the blind's answer. The blind who committed a misdeed and told the truth has a longer siglatent period. |
