Abstract
The attentional blink (AB) is the phenomenon in which the identification of the second of two targets (T2) is attenuated if it is presented less than 500 ms after the first target (T1). Although the AB is eliminated in canonical word conditions, it remains unclear whether the character order in compound words affects the magnitude of the AB. Morpheme decomposition and transposition of Chinese two-character compound words can provide an effective means to examine AB priming and to assess combinations of the component representations inherent to visual word identification. In the present study, we examined the processing of consecutive targets in a rapid serial visual presentation (RSVP) paradigm using Chinese two-character compound words in which the two characters were transposed to form meaningful words or meaningless combinations (reversible, transposed, or canonical words). We found that when two Chinese characters that form a compound word, regardless of their order, are presented in an RSVP sequence, the likelihood of an AB for the second character is greatly reduced or eliminated compared to when the two characters constitute separate words rather than a compound word. Moreover, the order of the report for the two characters is more likely to be reversed when the normal order of the two characters in a compound word is reversed, especially when the interval between the presentation of the two characters is extremely short. These findings are more consistent with the cognitive strategy hypothesis than the resource-limited hypothesis during character decomposition and transposition of Chinese two-character compound words. These results suggest that compound characters are perceived as a unit, rather than two separate words. The data further suggest that readers could easily understand the text with character transpositions in compound words during Chinese reading.
Highlights
The human visual system has developed a remarkable capacity to process sequential perceptual information
The attentional blink (AB) refers to an observer’s attenuated ability to report the second of two targets (T2) in a rapid serial visual presentation (RSVP) stream if it appears within 500 ms after
The accuracy in identifying T2|T1 was almost identical across all stimulus onset asynchrony (SOA) under the transposed, canonical, and reversible word conditions, indicating the AB was absent (Figure 3). These results revealed that the reversibility and transposition of the characters within a compound word contributed to the elimination of AB
Summary
The human visual system has developed a remarkable capacity to process sequential perceptual information. There are clear limitations to human conscious perception, as evidenced by the attentional blink (AB). Character Transposition and Attentional Blink the first target (T1). There has been a substantial research effort dedicated to the underlying cause of this robust attentional phenomenon (Dux and Marois, 2009; Martens and Wyble, 2010). Priming is determined by the degree of decreased impairment in the magnitude of the AB when T1–T2 are related (Maki et al, 1997; Potter et al, 2005), and the priming effect occurs regardless of the stimulus onset asynchrony (SOA) between T1 and T2 (Juola et al, 2000) or whether the target shown during the AB task is identified (Martens et al, 2002)
