Effect Of Overconfidence On Picture Superiority Effect In Second Language Vocabulary Learning Under The Explicit And Implicit Condition

Previous studies have confirmed that the picture superiority effect in the learning ofsecond language vocabulary, but recent studies have found that the confidence level ofparticipants will impact this effect. Blind confidence is not good for memory. Moreover,previous studies merely investigated the picture superiority effect of explicit memory underexplicit cues. However, there are many difference between implicit memory and explicitmemory in the mechanism and characteristics, so it is an issue whether the overconfidencelevel will affect the explicit memory as impact implicit memory. Additionally, previousstudies is based on the English alphabet, whereas, Korean characters has a more graphicalfeature in spelling form, thus we need to explore whether picture superiority effect inOriental language learning is the similar. The present study design two experimentsaccording to these problems to be resolved. Experiment1aims to explore whether picturesuperiority effect will both display in explicit and implicit memory, and whether there isoverconfidence to impact picture superiority effect. If participants showed overconfidence,experiment2is to eliminate the overconfidence by instruction and reveal the influence ofoverconfidence on picture superiority effect, and discover the difference of influence betweenexplicit and implicit memory. The results showed that:The picture superiority effect in second language vocabulary learning would beimpacted by learners’ confident level, and the overconfidence would result in the effectdisappear.After eliminated overconfidence by warnings, the results showed that picture learningcombined vocabulary learning is superior to word to word translation learning, and thepicture superiority was obvious. Furthermore, confident level could positively predict theperformance of memory.Picture superiority effect was more available in the implicit memory task.In short, the whole study suggested that overconfidence would mask picture superiorityeffect in a certain extent.
