网络词语与非网络词语的知觉差异:时间知觉、空间距离知觉与知觉范围

根据具身认知理论,人们的认知会受到身体活动的影响。网络环境下人的身体活动受到限制,因而其认知活动与非网络环境存在很大的差异。本研究目的在于考察人们对网络词语与非网络的日常词语的时间知觉,空间距离知觉与知觉范围是否有差异。结果发现被试对网络词语的时间知觉更长;网络词语的空间距离感与日常词语没有显著差异;在启动网络词语之后,被试的知觉范围缩小,对中心刺激的反应显著快于边缘刺激。本研究发现了网络词语加工在时间知觉和知觉范围上的变化。

Perceptual difference between internet words and real-world words: temporal perception,distance perception,and perceptual scope

According to embodied cognition theory,cognitive activity takes place in the context of a real-world environment,and it inherently involves perception and action,therefore our cognitive process is grounded in our sensorimotor systems.Internet is a virtual environment,in which sensorimotor system is inhibited.Therefore,our cognitive process is different in internet environment compared to real-world environment.In this study,we aimed to compare the cognitive differences between internet environment and real-world environment on temporal perception,distance perception,and perceptual scope.Because internet words and real-world words are used in our life frequently and can be processed proficiently,we use internet words (such as "website","WeChat"),and real-world words (such as "school","canteen") to induce the internet environment and realworld environment.In Experiment 1,we compared the temporal perception on internet words and real-world words by using temporal generalization method.A random line square presented 800 ms or 2000 ms,then a word appeared.The word presented 600 ms,800 ms or 1000ms when square presenting 800 ms;1600 ms,2000 ms,or 2400 ms when square presenting 2000 ms.Then the participant was asked to judge whether the time that word presented was the same with the square.In Experiment 2,we used a picture-word version of Stroop task to test the difference of psychological distance between internet words and real-world words.Participants indicated whether the target word appearing within the picture was near or far.In Experiment 3,we used prime paradigm to test whether the intemet words priming decreased participants' perceptual scope compared to real-world words.Participants were judged the letters ("E" or "H") appeared in different places (center or peripheral) in the screen after priming words presenting 2s.In Experiment 1,we compared the ratio that participants judged the time the word presenting was the same with square between the internet and real-world condition.The results showed that the ratio was higher in the internet condition than real-world condition when the word presented 600 ms,and the ratio was lower in internet condition than real-world condition when the word presented 2400 ms.The results suggested the temporal perception of internet words was longer than real-world words.In Experiment 2,we did not find any significant interaction effect between distance and the word type.Therefore,there was no difference of psychological distance between internet words and real-world words.In Experiment 3,the results showed that there was no difference on reaction time between the letters appeared in center and peripheral screen after the real-world words,but it's significantly faster when the letters appeared in the center screen than peripheral screen after the internet words.The results suggested that internet words decreased the perceptual scope.In summary,current study showed that participants judged internet words presenting longer than real-world words,the perceptual scope was decreased after internet words presented,and no difference between internet words and real-world words was found on the psychological distance perception.The temporal perception and perceptual scope differed between internet environment and real-world environment.This study suggested that internet environment influenced people's perception processing compared to real-world environment.
