【摘要】 冗余信号效应表明,当多个刺激在不同感觉通道同时呈现时,人们对多通道呈现刺激的时间感知快于单通道呈现刺激的时间感知,即存在跨通道融合现象。本研究将该效应牵引至在线视频播放事发生卡顿的加载界面,相比单通道(视觉通道)动画Loading,用户是否会对双通道(视觉通道与听觉通道)动画Loading的时间感知进行低估,以优化和丰富Loading(加载)类型。本研究选用抑郁-焦虑-压力量表筛选近一周情绪稳定的在校大学生40名,采用在线视频播放卡顿加载任务,以时间复制法来探讨双通道动画Loading对用户时间感知的影响。研究结果表明:被试对双通道动画Loading的时距估计显著低于单通道动画Loading的时距估计,显现在四种不同Loading呈现时长(5s、10s、20s和50s)下。被试对时距的估计随着动画Loading呈现时长的增加而增加,并且倾向于高估较短时距(5s、10s)的双通道动画Loading,低估较长时距(20s、50s)的双通道动画Loading,并且对于较短时距的时距估计更加准确。此外,进一步分析发现,虽然被试在双通道动画Loading条件下的时距估计均显著低于单通道动画Loading条件下的时距估计,但这并不能体现出不同Loading呈现时长下双通道动画Loading的时距低估幅度是否存在显著性差异,因此本研究采用单、双通道Loading条件下的时距估计的差值做进一步分析统计。为了尽量保证结果为正值,统计分析在时距估计上采用单通道Loading条件下的时距估计减去双通道Loading条件下的时距估计。单因素重复测量方差分析发现,当Loading呈现时长大于等于10s时,随着加载等待时间越长,被试对单双通道动画Loading的时距估计差异显著增大,存在更大的双通道优势。更多还原

【Abstract】 The redundant signal effect shows that when multiple stimuli are presented simultaneously in different sensory channels,people’s temporal perception of multi-channel stimuli is faster than that of single-channel stimuli,that is,there is cross-channel fusion.This study draws this effect onto the Loading interface of Cottonwood for online video playback events,compared to single-channel(visual channel)animation Loading,whether the user will underestimate the time perception of two-channel(visual and auditory) animated Loading to optimize and enrich the Loading type.This study used the depression-anxiety-stress scale to screen 40 college students who were emotionally stable for nearly a week.The Cottonwood loading task was played in an online video,the time replication method was used to explore the effect of two-channel animation Loading on user’s time perception.The results show that the estimated time duration of two-channel animation Loading is significantly lower than that of single-channel animation Loading,and appears under four different Loading durations(5s,10s,20s,and50s).The subjects’ estimation of the duration increased with the increase of the duration of the animation Loading,and tended to overestimate the short duration(5s,10s) and underestimate the long duration(20s,50s) of the dual-channel animation Loading,and for the shorter time interval,the time interval estimation is more accurate.Furthermore,it was found that although the time interval estimation under two-channel animation Loading was significantly lower than that under single-channel animation Loading,the time interval estimation under two-channel animation Loading was significantly lower than that under single-channel animation Loading,and the time interval estimation under two-channel animation Loading was significantly lower than that under single-channel animation Loading,but the time interval estimation under two-channel animation Loading was significantly lower than that under single-channel animation Loading,however,this does not show whether there is a significant difference in the underestimation of the time interval of two-channel animation Loading under different Loading lengths,therefore,this study uses the difference of time distance estimation under single-channel Loading and double-channel Loading to make further analysis and statistics.In order to ensure that the result is positive,the estimation of time interval under single-channel Loading is used to subtract the estimation under two-channel Loading.One-way repeated measures analysis of variance found that when Loading length was longer than or equal to 10 seconds,with the longer Loading waiting time,the difference of time interval estimation between single-channel and double-channel animation Loading significantly increased,there is a greater advantage to dual channels.更多还原
