Manipulations that disrupt generative processes decrease conformity to examples: evidence from two paradigms.

Participants in six experiments viewed experimenter-provided examples of space creatures (Experiments 1-3) or nonwords (Experiments 4-5b) and then created their own novel space creatures or nonwords. Consistent with previous research, people borrowed many of the features found in the examples despite instructions to avoid using any aspects of the experimenter's examples. However, requiring people to include a designated shape in their space creatures or a designated letter in their nonwords attenuated this effect. Additionally, the type of shape or letter (conventional versus unconventional) also affected conformity. These results suggest that the strategies that people use to create novel products can affect the level of conformity and also highlight the importance of adopting unconventional, or at the very least, new strategies when creating new products.

Warnings reduce the magnitude of the imagination inflation effect.

Imagination inflation occurs when people increase their confidence that an event actually happened after imagining the details of the event. The purpose of this study was to determine whether warning people about the imagination inflation effect would reduce their tendency to inflate their ratings of the imagined events. In one condition, we warned participants about the deleterious effects of imagining distant events. Compared with a control group that did not receive a warning, this group produced a significantly smaller imagination inflation effect. We discuss these results and the imagination inflation effect in the context of 2 theories designed to explain the cognitive processes that produce this effect.

Source monitoring in a generative task.

Following exposure to experimenter-provided examples of space creatures, people tend to conform to the features contained in the examples when creating their own novel space creatures. In three experiments, we manipulated factors known to affect source-monitoring accuracy to determine how these manipulations would influence conformity to experimenter-provided examples. In Experiment 1 we altered people's cognitive agenda by means of the instructions given before the drawing task. In Experiment 2 we examined how time pressure would affect the level of conformity, and in Experiment 3 we manipulated the availability of the creatures during the drawing task by making them available to half the participants. Conformity decreased when extended source-monitoring processes were engaged and increased when these processes were disrupted. The results from the three experiments were consistent with the principles of the source-monitoring framework.

Mental simulation inflates performance estimates for physical abilities.

In five experiments, we examined how mental simulation of physical activities affected estimates of one's ability to perform the same activities. In Experiment 1, participants who simulated lifting aheavy object estimated that they could lift more weight than did participants who did not perform the simulation. In Experiment 2A, the frequency with which participants performed the simulation exercises was manipulated. In Experiments 2B and 2C, we manipulated the amount of weight that people simulated lifting in order to address potential alternative explanations of the inflation effect. In Experiment 3, mental simulations were manipulated within subjects. In all the experiments, the simulated events showed inflated estimates, as compared with nonsimulated events. These results were interpreted in the context of the misattribution-of-familiarity account of imagination inflation.
