The Chinese phonograms consist of a semantic radical and a phonetic radical. The two types of radicals have different functional contributions to their host phonogram. The semantic radical typically signifies the meaning of the phonogram, while the phonetic radical usually contains a phonological clue to the phonogram’s pronunciation. However, it is still unclear how they interplay with each other when we attempt to recognize a phonogram because previous studies rarely manipulated the functionality of the two types of radicals in a single design. Using a full factorial design, the present study aimed to probe this issue by directly manipulating the functional validity of the two types of radicals in a lexical decision task with both behavioral and event-related potential (ERP) measurements. The results showed that recognition of phonograms which were related to their semantic radicals in meaning took a shorter reaction time, showed a lower error rate, and elicited a smaller P200 and a larger N400 than did recognition of those which had no semantic relation with their semantic radicals. However, the validity of phonetic radicals did not show any main effect or interaction with that of semantic radicals on either behavioral or ERP measurements. These results indicated that semantic radicals played a dominant role in the recognition of phonograms. Transparent semantic radicals, which provide valid semantic cues to phonograms, can facilitate the recognition of phonograms.
Third-party punishment (TPP) is a substantial and special kind of altruistic behaviors, which could help maintain social norms and human cooperation. A large body of research has studied norm conformity like fair behaviors and its underlying cognitive mechanisms, merely few studies, however, have discussed norm enforcement behaviors like TPP and its cognitive process. One issue of strong interest is the way how cognitive control influences TPP. Thus, through (1) exploring the specific role of cognitive control in TPP by means of employing different technical methods; (2) from the perspective of developmental psychology, examining how the effects of cognitive control vary by stages of development, particularly focusing on preschoolers and adolescents, who are undergoing rapid development of cognitive control, the present project aims to deepen the understanding of the cognitive basis of TPP, explain the developmental trajectory of TPP, and help build a psychological model for the TPP decision making.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
