An Exploration of Individual and Collective Reversal Learning in Rats
Skills taught in isolation can break down in social settings.
01Research in Context
What this study did
Gildea et al. (2025) trained rats to learn cue–outcome links.
Some rats learned alone. Others learned in pairs.
Later, all rats were tested in pairs to see if training style mattered.
What they found
Alone-trained rats did fine when tested alone.
When those same rats were moved to a pair test, they stumbled.
Group-trained rats kept steady no matter the test set-up.
How this fits with other research
Halpern et al. (1966) showed that quick reversals within one session sharpen control in single rats.
Gildea extends that idea: the training context you start with locks in habits that may clash later.
Haynes et al. (2022) saw rats flip choices when delays grew.
Their within-session shifts echo Gildea’s point: prior context guides later flexibility.
Mason et al. (2026) found relapse in one schedule part after changes in another.
Both papers warn: what happens in one setting leaks into the next.
Why it matters
Your client may master a skill at a table alone.
Check if the skill holds when peers join.
If not, weave partners into early teaching.
A small group trial now can save retraining later.

03Original abstract
Although associative learning research has been conducted for more than a century, little is known about learning processes when subjects are not alone, but in a group—a phenomenon termed collective learning. In collective learning situations, the behavior of conspecifics may serve as an associative cue for learning, like any other stimulus during individual learning. Two experiments investigated how individual versus collective training affects associative learning. Experiment 1 utilized a simultaneous discrimination task, whereas Experiment 2 implemented a serial go/no-go discrimination task. In both experiments, rats were trained either individually or collectively, exposing them to two distinct stimuli with only one of them signaling the availability of food reinforcement. Following acquisition training, all rats were tested both individually and collectively. Contingencies were then reversed: the previously nonreinforced stimulus now signaled the availability of food, and the previously reinforced stimulus now signaled the absence of food. Following reversal training, the rats were again tested individually and collectively. Results from both experiments suggest that the training condition (individual or collective) had little effect on learning the cue–outcome association. However, individual training negatively affected test performance in a collective context. These results suggest that collective training may have a facilitative effect on learning and points out key methodological considerations for more in-depth examination of this effect.
