This chapter reviews studies published in American Psychological Association (APA) journals from 2003-2004 and additional studies (received in response to listserv requests) that used the Internet to collect data (N=121 total studies). Specific examples of three kinds of Web-based research are reviewed: (a) translational (established methods and research questions are adapted to the Web), (b) phenomenological (behavior on the Web is the focus of study), and (c) novel (methodologically innovations unique to Web-based research). Among other findings, our review indicated that 21% of APA journals published at least one article that reported on Web-based research, most Web-based psychological research uses experimental methods, a surprising number use college student samples, and deception in Web-based research is not uncommon. Strengths and weaknesses of Web-based psychological research in general, and our sample of studies in particular, are reviewed with special attention to possible concerns about sampling and the use of deception.
This article presents a three-factor anatomical model of human idea generation and creative drive, focusing on interactions between the temporal lobes, frontal lobes, and limbic system. Evidence is drawn from functional imaging, drug studies, and lesion analysis. Temporal lobe changes, as in hypergraphia, often increase idea generation, sometimes at the expense of quality. Frontal lobe deficits may decrease idea generation, in part because of rigid judgments about an idea's worth. These phenomena are clearest in verbal creativity, and roughly parallel the pressured communication of temporal lobe epilepsy, mania, and Wernicke's aphasia-compared to the sparse speech and cognitive inflexibility of depression, Broca's aphasia, and other frontal lobe lesions. The phenomena also shape non-linguistic creativity, as in that of frontotemporal dementia. The appropriate balance between frontal and temporal activity is mediated by mutually inhibitory corticocortical interactions. Mesolimbic dopamine influences novelty seeking and creative drive. Dopamine agonists and antagonists have opposite effects on goal-directed behavior and hallucinations. Creative drive is not identical to skill-the latter depends more on neocortical association areas. However, drive correlates better with successful creative output than skill does. Traditional neuroscientific models of creativity, such as the left brain - right brain hemispheric model, emphasize skills primarily, and stress art and musical skill at the expense of language and mathematics. The three-factor model proposed here predicts findings in a broad range of normal and pathological states and can be tested in many experimental paradigms.
