Different bias mechanisms in recall and recognition of conceptual and perceptual information of an event

Abstract

The aim of this research was to study the memory and response bias for conceptual and perceptual information in the recall and recognition of an event. The participants watched a movie trailer video and their memory of verbal and visual actions and details was evaluated using specific recall questions or a true/false recognition task. The participants recalled and recognized actions better than details, and visual information better than verbal information. Memory biases affected recall and recognition differently. The participants showed a high tendency to accept false verbal actions consistent with the gist of the event as true in the recognition task, while in the recall task the participants were more likely to answer incorrectly questions involving visual perceptual details. These results reflect the different mechanisms which are involved in the processing and cognitive management of conceptual and perceptual information of an event.
