“…Baddeley et al (1998), for example, found that the deviation of randomness in generated key presses increased when an irrelevant memory load was larger, which shows that maintaining a memory load may interfere with cognitive control processes needed for the generation task. Several studies have also reported poorer recall on a memory task when an unrelated random generation task was performed concurrently (e.g., Fisk & Sharp, 2003;Macizo, Bajo, & Soriano, 2006;Towse & Cheshire, 2007;Vandierendonck, 2000aVandierendonck, , 2000bVandierendonck, De Vooght, & Van der Goten, 1998a, 1998bVandierendonck, Kemps, Fastame, & Szmalec, 2004), suggesting that random generation interferes with maintenance of unrelated memory contents. Based on these findings, the expectation may be formulated that performing VTS under a memory load could result in the usage of shorter chains.…”
