Objective: To explore the influence of different encoding methods and different category words
on recognition of conjunctions. Methods: 66 college students were recruited as subjects, using the three
bond reaction paradigm of connectiveness recognition, and using 3 (category types: human word pair,
animal word pair, nonbiological word pair) × 2 (coding mode: intentional coding, unintentional coding)
mixed experimental design. Results: (1) The correct rate of nonbiological word pairs was significantly
higher than that of human and animal word pairs, and the reaction time was the shortest; (2) The score
of connexion recognition of intentional encoding was significantly higher than that of unintentional
encoding, but there was no significant difference in reaction time; (3) The edge of interaction effect
of the two independent variables is significant. The accuracy of nonbiological word pair association
memory under intentional encoding level is significantly higher than that of human word pair association
recognition under unintentional encoding level, and the reaction time is not significant. Conclusion:
The processing mechanisms of associative memory and item memory are inconsistent, individuals
can recognize non biological word pairs more quickly and accurately, and the complexity and neural
mechanism of information processing differences deserve further study.
