Dimensional Complexity
Dimensional Complexity of the EEG During Divergent and Convergent Thought ProcessesCreativity is one of the most difficult mental functions to study. While a concrete definition remains illusive, it has been established as a multifaceted phenomenon (Kitto, Lok & Rudowicz, 1994). One facet that is an important component of creative potential is divergent thinking (Vosburg, 1998), this is the ability to generate several alternative solutions to a problem. The mental processing involved occurs in such a way as to activate as many mental representations as possible, maintaining only a weak connection to the original stimulus (Molle, Marshall, Wolf, Fehm & Born, 1999). One of the more popular methods for assessing creative potential then, is through the administration of divergent thinking tests (Mumford, Marks, Connelly , Zaccaro & Johnson, 1998). In these tests people are requested to generate as many alternative answers as possible to a series of ill-defined, open-ended problems (Brown, 1989). The number of ideas used in answering the problem are counted, and can be taken as a performance measure of creative thinking. On the other side of the scale is convergent thinking. Here, ve
These tasks will consist of textbook type problem solving questions, where only one right answer exists. Research into the physiological footing of creative thought has the potential to be of great aid to the field of creative psychology, lending much needed validity to many of the ideas being theorized. Namely, points will be awarded for the number of responses given. It can be assumed that the dimensional complexity of the EEG indicates the complexity of neural dynamics underlying the EEG time series. Between task switches, each subject will be asked to relax and think of being in some pleasing environment. EEG recordings during this time will be used as an extra comparison to those seen during the tasks.
