Abstract
The present study examined whether individuals experienced the same cognitive advantage for online self-relevant information (nickname) as that experienced for information encountered in real life (real name) through two experiments at both the behavioural and neural levels (event-related potential, ERP). The results indicated that individuals showed the same cognitive advantage for nicknames and real names. At the behavioural level, a nickname was detected as quickly as the real name, and both were detected faster than a famous name; at the neural level, the P300 potential elicited by one’s nickname was similar to that elicited by one’s real name, and both the P300 amplitudes and latencies were larger and more prolonged than those elicited by other name stimuli. These results not only confirmed the cognitive advantage for one’s own nickname and indicated that this self-advantage can be extended to online information, but also indicated that the virtual self could be integrated into the self and further expanded individuals’ self-concept.
Highlights
The present study examined whether individuals experienced the same cognitive advantage for online self-relevant information as that experienced for information encountered in real life through two experiments at both the behavioural and neural levels
This study aimed to examine the cognitive advantage for online self-relevant information, and it was hypothesized that individuals may show the same cognitive advantage for online self-relevant information as that exhibited for self-relevant information in real life
Considering the cognitive advantage for self-relevant information, as well as the same social functions of nickname and avatar with individuals’ real names and faces[12,27,28,32], this study aimed to investigate whether individuals were equipped with the same cognitive advantage for online self-relevant information as that in real life through two experiments at both the behavioural and neural levels
Summary
The present study examined whether individuals experienced the same cognitive advantage for online self-relevant information (nickname) as that experienced for information encountered in real life (real name) through two experiments at both the behavioural and neural levels (event-related potential, ERP). A nickname was detected as quickly as the real name, and both were detected faster than a famous name; at the neural level, the P300 potential elicited by one’s nickname was similar to that elicited by one’s real name, and both the P300 amplitudes and latencies were larger and more prolonged than those elicited by other name stimuli These results confirmed the cognitive advantage for one’s own nickname and indicated that this self-advantage can be extended to online information, and indicated that the virtual self could be integrated into the self and further expanded individuals’ self-concept. Considerable studies with different experimental paradigms have indicated the attention advantage for various self-relevant stimuli, such as one’s own name, face, body, sound and handwriting[7,8,15,16]
