Effects of prenatal stress on novelty preferences during spatial, object, and context trials. For spatial trials prenatal stress (PS) significantly reduced the % of visits (A) and % time investigating (B) novel locations in males but not females. PS did not significantly affect the % of visits or % time investigating objects during object or context trials, however, nonstressed males displayed above chance preferences for novelty during object trials (†). NS females: spatial n=9; object n=8; context n=9. PS females: spatial n=8; object n=10; context n=10. NS males: spatial n=6; object n=9; context n=9. PS males: spatial n=9; object n=8; context n=9. Data expressed as mean ± SEM. Asterisk (*) indicates a significant difference (p<0.05) between groups. Cross (†) indicates an above chance preference for novelty (>50%) in that group.
