摘要
采用口头估计的方法,考察刺激的数目和呈现方式对时距估计的影响。以时距估计的平均值、准确性和变异性为指标,结果表明:(1)数目多少影响时距估计的平均值和准确性,数目少引起低估,数目多导致高估,数目多少与时距长度一致时,准确性高。(2)呈现方式影响时距估计的变异性,同时呈现时变异性最大;(3)数目和呈现方式的交互作用显著,固定频率和变化频率呈现时,数目影响时距估计。(4)随着时距的增加,时距估计的平均值由高估向低估,准确性由低向高发展。这表明时距和数目在心理表征上存在连接,数目和呈现方式在不同的时间范围内影响时间加工。
Adopting temporal estimation method was to examine the effects of number and numerary presentation mode on duration estimation.Using estimated length of interval,accuracy and variation as dependent variable.The results showed that：（1） Average values and accuracy were affected by number.Small number resulted in underestimation while more number produced overestimation.The accuracy was high when duration accorded with number.（2） Numerary presentation mode significantly influenced temporal variation,of which largest was simultaneous presentation.（3） Interactive effect between number and numerary presentation mode was significant.Number and numerary presentation mode dependently determined time estimation.（4） Average values and accuracy developed from overestimation to underestimation and from low to high separately as time increased.The results indicated that time and number have a link in mental representation.Number and numerary presentation mode affected time processing during different interval range.
