“…Many studies have demonstrated in the last few years that perceptual representations are active during conceptual processing, although a debate exists on whether perceptual, symbolic, or both processes are either necessary and/or sufficient for conceptual processing (Louwerse et al, 2015). In semantic judgment tasks, it has been observed that highfrequency words are processed faster than low-frequency words (Monsell, Doyle, & Haggard, 1989) and that lexical co-occurrence frequencies influence and predict response times which directly supports the symbolic account (Louwerse et al, 2015). In the case of valence, it has been reported that positive words are significantly more frequent than negative words (Warriner, Kuperman, & Brysbaert, 2013) and that the frequency of word sequences, where positive words precede negative words, tends to be significantly higher than that of sequences where the reverse order applies (Louwerse et al, 2015).…”
