Collaborative Inhibition and Semantic Recall: Improving Collaboration Through Computer-mediated Communication

Two experiments investigated the recall of nominal and collaborating groups to test the following hypotheses: (i) semantic memory, as well as episodic memory, is disrupted by collaborative recall and (ii) both episodic and semantic recall will be greater in groups collaborating via computer-mediated communication (CMC) than groups collaborating face to face. Experiment 1 investigated different collaborative constellations (nominal, face to face and parallel CMC) in a series of episodic and semantic word recall tasks. In Experiment 2, collaborative groups (nominal, face to face, parallel CMC and cyclic CMC) completed a Scrabble task in which they were required to generate words from a set of 12 letters. Both experiments demonstrated that collaborative inhibition was present in semantic recall. Parallel CMC improved recall by comparison with face-to-face collaboration in both experiments, whereas cyclic CMC did not. The underlying causes of collaborative inhibitory effects and the potential for reducing them with CMC are discussed.Copyright (c) 2016 John Wiley & Sons, Ltd.
