Bonferroni-corrected paired t-tests (in which only values with a p < 0.017 were considered significant) found a significantly lower rate of reference memory errors on the final day when compared to the first day (t(7) = 3.31, p = 0.013) and a significantly lower rate of reference memory errors on the probe day when compared to the first day (t(7) = 4.03, p = 0.005).
Because rats varied in the extent to which they explored the maze, we also analyzed a composite percent correct measure which was the number of correct choices (rewards retrieved) divided by the total number of choices made (the sum of the number of rewards retrieved/reference memory errors, and errors of commission).
While this represents an approximation, it enables information on different classes of memory error to be incorporated into the dependent variable in samples where absolute levels of each type of error are small.
In order to evaluate differences between groups in radial arm-maze task, separate repeated-measures ANOVA were calculated on number of working memory errors and number of reference memory errors with group (Control, 6-OHDA, 6-OHDA + AE (150 mg/kg) and (6-OHDA + AE (300 mg/kg)) as between-subject factor and days (1 to 7) as within-subjects factors.
These results underscore the value of parsing the sources of memory errors in fMRI studies because of the non-linear nature of the brain-behavior relationship, and suggest that group comparisons need to be interpreted in more specific behavioral contexts.
Notably, both the numbers of long-term and short-term memory errors represented overestimates of the actual error rate as long as omission errors were performed.
Within this review specific examples about the formation of false memories were given to illustrate the variety of memory errors related to diverse stages of processing.
Specific examples about the formation of false memories will be given in this review article to illustrate the variety of memory errors related to diverse stages of processing.
Values for task latency, the total number of visits, the number of omission errors and the rate of re-entry (working memory) errors as a percentage of total visits were compared between mazes using repeated measures ANOVA.
Semantic interference triggered the false memory rates to be higher than those of other types of memory errors.
