Iteration can help people improve ideas. It can also give rise to fixation, continuously refining one option without considering others. Does creating and receiving feedback on multiple prototypes in parallel, as opposed to serially, affect learning, self-efficacy, and design exploration? An experiment manipulated whether independent novice designers created graphic Web advertisements in parallel or in series. Serial participants received descriptive critique directly after each prototype. Parallel participants created multiple prototypes before receiving feedback. As measured by clickthrough data and expert ratings, ads created in the Parallel condition significantly outperformed those from the Serial condition. Moreover, independent raters found Parallel prototypes to be more diverse. Parallel participants also reported a larger increase in task-specific self-confidence. This article outlines a theoretical foundation for why parallel prototyping produces better design results and discusses the implications for design education.

The management of unhelpful negative emotions has been addressed by two literatures, one focused on coping via humor, and the other focused on emotion regulation. In the present study, we directly compared humorous coping with conventional (serious) reappraisal. We expected humorous coping to be more effective than serious reappraisal in the short and longer term. Fifty-seven participants used either humorous coping, serious reappraisal, or attended naturally while viewing negative pictures and then rated their positive and negative emotional responses. One week later, participants viewed and rated the pictures again. In the short-term, while humorous coping was more difficult than serious reappraisal, it was more effective in down-regulating negative and up-regulating positive emotions. In the longer-term, both strategies had beneficial effects on positive emotions while humorous coping was more beneficial than serious reappraisal in down-regulating negative emotions. This is the first study that empirically shows short and longer-term beneficial effects of humorous coping versus serious reappraisal in the context of emotions elicited by negative stimuli.
