ABSTRACT
Personal computers allow multitasking among a greater variety of content than has ever been possible on a single device. We logged all switches made for 4 days for 30 people on personal computers used in natural environments. The median time before a switch occurred was 11 sec, shorter than previously observed. We also measured individual differences in appetitive versus defensive motivations to switch. Those people high on both motivations (Coactives) had the most switches per session. Risk takers had the shortest content segment lengths; risk avoiders and inactives were lower on the number of switches and anticipated arousal. Different patterns of content selection, in addition to switching behavior, were also observed for the different motivation activation groups. Results highlight how threads of experience that mix radically different short media segments may better define how people now search, process, and evaluate information. Implications in light of technological trends and individual differences are discussed.
Notes
1. Pilot testing revealed this was the most frequent sampling rate not experienced as intrusive.
2. Note that other colors appear present in these squares as a result of the rapidity of switching between content types. For instance, stripes of orange are the result of several short splices of e-mail (yellow) and other content beyond work, entertainment, and news (red). Similarly, purple stripes emerge from quick switches between entertainment (blue) and such content. This effect reflects the likely psychological dissolve that takes place when processing such jumbles of types of content.
