Guppies Show Behavioural but Not Cognitive Sex Differences in a Novel Object Recognition Test
The novel object recognition (NOR) test is a widely-used paradigm to study learning and memory in rodents. NOR performance is typically measured as the preference to interact with a novel object over a familiar object based on spontaneous exploratory behaviour. In rats and mice, females usually have greater NOR ability than males. The NOR test is now available for a large number of species, inc...
متن کاملSex differences in object recognition are modulated by object similarity.
How females and males differ in performance in object recognition tasks appears to vary among mammalian species, with female superiority found in the laboratory rat and humans but not in the laboratory mouse. Here we assessed sex differences in object recognition in C57BL/J6 mice by varying the similarity between objects to be learned. Females outperformed males in object recognition when the n...

Recently, Strand, Deary, and Smith (2006) reported sex differences for over 320,000 students 11-12 years old on the Cognitive Abilities Test. Although mean differences were small, score distributions for males were more variable. Males were also overrepresented at the upper and lower extremes of the score distributions on the Quantitative and Nonverbal batteries and at the lower extreme of the ...
متن کاملSex-Specific Differences in Shoaling Affect Parasite Transmission in Guppies
BACKGROUND Individuals have to trade-off the costs and benefits of group membership during shoaling behaviour. Shoaling can increase the risk of parasite transmission, but this cost has rarely been quantified experimentally. Guppies (Poecilia reticulata) are a model system for behavioural studies, and they are commonly infected by gyrodactylid parasites, notorious fish pathogens that are direct...

Background: Most studies have investigated the effect of brain pathological aging on information recall and recognition memory performance of patients (by using a yes/no procedure), and for this reason, provide a partial picture of memory deficits and other factors involved in recognition memory such as discriminability and response bias are not considered. In this regard, the aim of present st...
