Fmr1 knockouts displayed decreased learning and memory capabilities in the delayed fear conditioning task. (a) Fmr1 KOs presented significantly decreased freezing in response to the first intertrial interval (ITI), second CS presentation and second ITI. (b) No significant differences by sex and genotype were detected in contextual fear conditioning. (c) Fmr1 KOs exhibited significantly reduced freezing to presentation of the CS in a novel context. Data are presented as mean ± SEM. * = p < .05
