Differential rates of attack, defense, and counterattack during the developmental decrease in play fighting by male and female rats.

abstract：:The effects of conditioning paradigm and interstimulus interval (ISI) were evaluated in this study of the development of associative learning in rats. The acquisition of classical eyeblink conditioning (EBC) was examined in two paradigms (trace vs. delay), with three different ISIs (short, medium, or long) at two ages...
