Yet by September 2000, it was discovered in corn taco shells, triggering a huge recall, tests on more than four billion bushels of corn and the cancellation of StarLink's federal registration.
The students who took the recall tests may "recognize some gaps in their knowledge," said Marcia Linn, an education professor at the University of California, Berkeley, "and they might revisit the ideas in the back of their mind or the front of their mind".
Quantitative data was gathered by pre, post, recall tests and an attitudinal questionnaire.
Recall tests, however, measure the number of items that are above a recall threshold, not memory strength per se.
The design and variables were the same as those in Experiment 1. Group A (n = 76) received three free recall tests, and Group B (n = 74) received two recall tests.
Group A (n = 40) took three free-recall tests with a short retention interval before the second test, and group B (n = 37) had two recall tests with a long retention interval.
After all definitions were studied, participants completed practice cued recall tests (e.g., "What is proactive interference?") in which they attempted to type the correct definition for each term.
However, embodiment manipulations using very subtle bodily cues run the risk of not finding substantial effects on performance measures such as recall tests.
In addition, measures of maternal attachment and delinquent peers were found to be associated with only one test of word recall ability and none of the three other recall tests.
Yet another possibility is that reminiscence occurs simply because there is more cumulative retrieval time on later than on earlier retrieval attempts, an explanation Roediger and Thorpe (1978) proposed to account for hypermnesia (the enhancement of memory over multiple recall tests that is seen when reminiscence exceeds forgetting).
Men's performance on number sequencing and word recall tests seemed to be linked to their level of sexual activity.
