Abstract

An occasional presence of bivalent stimuli in a block of univalent trials can elicit a slowing of the response on all subsequent univalent trials. This type of modulation of cognitive control is termed the bivalency effect. To explore whether this modulation is task specific, this study used a triplet task switching paradigm, with three following tasks that were presented concussively: a shape color judgment (red vs. blue), a number parity judgment (odd vs. even), and a letter case judgment (lowercase vs. uppercase). The event-related potential (ERP) results showed that (1) the bivalency effect was reflected by the decreased amplitude of N2 and P3a over the frontal region for both the color and letter tasks; (2) the bivalency effect occurred earlier for the color task compared with that for the letter task; (3) for the number parity task, the bivalency effect was observed in the increased N1 and the decreased P2p over the parietal region. These findings indicate that the modulation of cognitive control is task-specific after the presentation of bivalent stimuli in task switching.

期刊介绍： PsyCh Journal, China''s first international psychology journal, publishes peer‑reviewed research articles, research reports and integrated research reviews spanning the entire spectrum of scientific psychology and its applications. PsyCh Journal is the flagship journal of the Institute of Psychology, Chinese Academy of Sciences – the only national psychology research institute in China – and reflects the high research standards of the nation. Launched in 2012, PsyCh Journal is devoted to the publication of advanced research exploring basic mechanisms of the human mind and behavior, and delivering scientific knowledge to enhance understanding of culture and society. Towards that broader goal, the Journal will provide a forum for academic exchange and a “knowledge bridge” between China and the World by showcasing high-quality, cutting-edge research related to the science and practice of psychology both within and outside of China. PsyCh Journal features original articles of both empirical and theoretical research in scientific psychology and interdisciplinary sciences, across all levels, from molecular, cellular and system, to individual, group and society. The Journal also publishes evaluative and integrative review papers on any significant research contribution in any area of scientific psychology
