In a hypothetical study on stress, half of the participants were told to write a short speech on an unfamiliar topic and then present it to a panel of experts who would judge their quality of work. After they presented their speech, they were then given a novel skill test that required some creativity, and the researchers recorded the type of strategies they employed. The other half were not asked to prepare such a speech, but were measured on the same novel skill test. How would the two groups be likely to differ?

A) The group that gave the speeches were more alert, and solved the novel skill test more quickly than the other group.

B) The group that gave the speeches used relatively basic strategies, and lacked the ability to change their strategy approach when needed.

C) The group that did NOT give speeches seemed to be more rested and stuck to simple methods for solving the novel skill test.

D) The group that did NOT give speeches could only solve the first half of the novel skill test easily, but failed to revise their approach when needed.
