In order to systematically grasp the research hotspots and evolution of technology affordances at home and abroad, and clarify the characteristics and development direction of technology affordances research in China, we use CiteSpace software to visualize and analyze the research literature on technology affordances at home and abroad. The research results of technology affordances at home and abroad are increasing, and the number of scholars who have researched technology affordances is large, but the cooperation among authors is generally scattered;among foreign research on technology affordances, information technology, knowledge technology, artificial intelligence, digital technology and web 2.0 are the hot spots of research;among domestic research on technology affordances, the connotation of technology affordances, social media, interaction design and user purchase are the hotspots;there are differences in the research frontiers of technology affordances research at home and abroad, but they all focus on the field of social media.展开更多

ERPs were measured while participants read the pun sentences containing dual meanings and made a judgement about the following probes and statements. The results showed that highly related probes in pun sentences elicited a smaller N400 and a larger LPC than moderately related probes in pun sentences. As for the comparison of sentence types, both highly and moderately related probes in pun sentences produce a smaller N400 and a larger LPC than those in control sentences. These results indicate that in the early stage of pun comprehension, semantic access to the literal meaning is easier through affordance derivation because of meaning dominance and frequency. In the late stage of integration, however,the intended meaning of puns can be facilitated and accessed through its privilege of affordance derivation activated by pun words in a pun context because of the priming context and its underlying intention. The study has discovered empirically that it is the affordance derivation,which connects the context and the dual meanings indicated by the pun words, that contributes to the different time courses and dynamic underlying neurocognitive mechanisms in comprehending puns in Chinese.展开更多
