PMID: 29293263
Atypical forgetting functions have been demonstrated in several recent studies of delayed matching to sample, in which experimental conditions are altered partway through the retention interval. The forgetting functions are...

Learn Behav
. 2015 Mar;
43(3):217-27.
PMID: 25784485
In delay-specific remembering, accuracy in delayed matching-to-sample tasks is enhanced after single delays or retention intervals relative to performance at other delays. In the differential-outcomes effect (DOE), accuracy is enhanced...

Behav Processes
. 2014 Oct;
112:22-8.
PMID: 25305066
Pigeons show the sunk cost effect in procedures in which their choice between two outcomes is biased by a prior investment. We review recent studies of the sunk cost effect...

Behav Processes
. 2014 Sep;
108:7-10.
PMID: 25219548
The reinforcement context model for performance in delayed matching to sample tasks (White and Brown, 2014) predicts the course of forgetting based on the assumption that rewards for extraneous behavior...

J Exp Psychol Anim Learn Cogn
. 2014 Jun;
40(1):38-54.
PMID: 24893107
We investigated the sunk time effect, persistence in a nonpreferred option owing to prior investment of time in that option. Pigeons chose between two concurrently available keys-2 fixed-interval (FI) food...

J Exp Psychol Anim Learn Cogn
. 2014 Jun;
40(1):22-37.
PMID: 24893106
We investigated the effect of prior investment on choice in pigeons, namely, the sunk cost effect, which is a tendency to continue an endeavor once a prior investment has been...

Behav Processes
. 2014 Feb;
105:1-5.
PMID: 24565982
Persistence in a losing course of action due to prior investments of time, known as the sunk time effect, has seldom been studied in nonhuman animals. On every trial in...

42(1):83-92.
PMID: 24233886
Wixted (Annual Review of Psychology, 55, 235 – 269, 2004) has argued that forgetting is due to consolidation failure. Previous research with humans and nonhuman animals has reported evidence for...

PMID: 23537922
Amount-dependent temporal discounting refers to the differential rates at which the values of large and small rewards are discounted over time. A lower rate of discounting of larger rewards is...
