Again, the median learning score for acquisition on day 1 was significantly lower in old foragers (Mann-Whitney U-test Z = −5.46, p<0.001, n = 82/90, df = 1,when bees with spontaneous response to the CS in trial 1 were excluded as before; Z = −6.05, p<0.001, n = 94/92, df = 1, when LS was calculated for all bees that were to be tested on day3).
We evaluated circumcised and uncircumcised men's sexual behavior using an 18-item risk propensity score and acquisition of incident infections of gonorrhea, chlamydia, and trichomoniasis.
Factors associated with early death included hematologic and hepatic failure, inappropriate antibiotic treatment, the logistic organ dysfunction system score and acquisition site of infection, similar to prior studies [ 5].
McNemar's test for correlated proportions was used to compare sensitivities and specificities; Chi-square analysis was used to compare AUCs; and Wilcoxon signed-rank test was used to compare image quality scores between acquisition types.
Thus, differences in subjective alertness scores at acquisition or test did not parallel differences in memory strength at test.
The scoring and acquisition criteria (75% rule) were similar to those used by Morrison et al. [9].
The reported scores at acquisition and test between participants who ran the memory test in the morning versus in the evening were not significantly different either.
That self-reports of alertness are not predictors of performance is further highlighted by the fact that, measured across the entire cohort, the correlations between d' on the one hand and reported alertness scores at acquisition and at test on the other were not significant.
We did not find a significant difference in the reported alertness scores at acquisition or test between the participants that remained awake for 12 hours or more during the retention period and the participants that remained awake for 4 hours or less.
Significant differences between mean scores during acquisition trial blocks in the MWM were assessed with two-way repeated measures ANOVA (General Linear Model/RM-ANOVA) with Tukey's post-hoc analysis for multiple comparisons using genotype and trial block number as sources of variation.
