>In the paper, Zabelina differentiates “convergent” from “divergent” thinking. The former is defined as seeking a specific solution to a problem, for example, the “correct” answer. The latter is characterized by idea generation where a large set of apt, novel or interesting responses would be suitable. Caffeine was shown to improve convergent thinking in the study, while consuming it had no significant impact on divergent thinking. Yeah, this was a bit was odd. IMO, problem solving begins with 'divergent' thinking and only later converges toward a, or the, solution. A study like this hinges upon how variables like'divergent thinking' were quantified, and there were no examples given of how they tested for either style of thinking here.
