Comparison of two positive reinforcing stimuli: Pups and cocaine throughout the postpartum period.
Abstract
This set of experiments investigated the appetitive or motivational processes underlying the performance of maternal behavior. The place preference paradigm was adapted to simultaneously investigate the reinforcing properties of cocaine and pups for maternal, lactating dams. These modifications allowed the authors to assess which stimulus, either a 10 mg/kg s.c. injection of cocaine or 3 pups, had the strongest reinforcing value. At Postpartum Days 10 and 16, the dams preferred the cocaine cue-associated chamber, whereas the dams tested at Postpartum Day 8 preferred the pup cue-associated chamber. Overall, the data revealed an interaction between the postpartum period at testing and the exhibited preference for cocaine or pups. Further testing will investigate the neural circuitry underlying the appetitive processes of each stimulus.

Rat mothers prefer young pups to cocaine.
“Rat mothers even prefer young pups to cocaine, indicating the power of their motivation toward maternal care (Mattson et al 2001).”

Dams prefer to spend time in areas previously associated with pups and exhibit preferences for cues associated with pups over those associated with drugs of abuse such as cocaine.
“Dams also prefer to spend time in areas previously associated with pups (i.e. conditioned place preference) and exhibit preferences for cues associated with pups over those associated with drugs of abuse such as cocaine (Ferris et al., 2005, Mattson et al., 2001, Mattson et al., 2003).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
