Abstract

There are two main aspects of word relatedness in literature: semantic relatedness and associative relatedness So far no any conclusive evidence to indicate which word relationship would speed up word perception under unconsciousness We criticized that the inconsistent results might due to the loose and diverted criterions In this study we aim to answer whether the benefit of semantic relatedness mentioned in previous researches would disappear with a more stringent definition Three word-pair conditions were then created: associated relatedness condition (AR) associative relatedness and semantic relatedness condition (ARSR) as well as no relatedness condition (NR) A sandwich masking paradigm was first utilized However the result was then be explained as conscious effect A better suppression psychophysical method breaking continuous flash suppression paradigm was then introduced to the following two experiments Surprisingly participants showed the longest reaction time detecting the AR condition followed by ARSR and the NR condition In addition the reaction time of AR condition minus NR is significant longer than the reaction time of ARSR condition minus NR The violation information was explained to induce one to react faster under unconsciousness Following the logic the semantic relatedness was then interpreted as an obstacle for word integration It’s might because that semantic relatedness is an artificial definition and cannot be connected as easily as associated relatedness We conclude that the benefit of semantic relatedness is disappear with a more stringent definition
