Abstract
Hoarding or hoarding behavior refers to the active storing and accumulation of food or other objects by an animal. Hoarding is often experimentally defined as the act of transporting food or objects, from some area outside the Ss home cage, back to the home cage. A typical hoarding experiment involves manipulation of an independent variable (e. g., amount of food deprivation, previous experience, early experience, strain of rat .• choice of hoarding material}, followed by measurement of the number of food pellets or objects hoarded during daily 30 min. hoarding trials. A hoarding trial involves allowing the subject access to the hoarding material by means of an alleyway attached to its home cage. Ss then have an allotted amount of time (e.g., 30 min., 24 hrs.) in which to transport the hoarding material to their home cages. To insure hoarding will take place, Ss are often food deprived prior to the first of a set of hoarding trials, or prior to each daily hoarding trial. Though laboratory rats will hoard food without being food deprived (Bindra, 1948) deprivation prior to trials facilitates the amount of hoarding (Morgan, Stellar & Johnson, 1943; Guerra, 1970).
