Time-place learning by pigeons, Columba livia.
Pigeons can learn when-plus-where rules, so give clients both cues.
01Research in Context
What this study did
Researchers worked with pigeons in a lab.
They set up three keys that lit up at different times.
Food was given only if the bird pecked the right key at the right moment.
The birds had to learn both WHERE and WHEN to respond.
What they found
The pigeons quickly learned the time-place rules.
They switched keys on cue and earned steady food.
The study showed birds can link space and time in one skill.
How this fits with other research
Bowe et al. (1983) found pigeons cared more about time than place.
That seems to clash, but the tasks differed.
In 1983 the birds only needed time to get news of food.
Here they needed both cues to get the food itself.
Green et al. (1987) showed position cues speed up pure time tasks.
M’s work extends that idea by proving birds can master the full combo.
Segal (1962) showed external clocks guide fixed-interval pecks.
M added the extra where rule, proving pigeons can juggle both pieces.
Why it matters
If you teach a child to wash hands before lunch, give two clear cues.
Use a picture of the sink and a kitchen timer.
Pairing place and time helps learners grasp the full routine faster.

03Original abstract
In each of two experiments, 2 pigeons received discrimination training in which food reinforcement for key pecking was conditional upon both spatial and temporal cues. In Experiment 1, food was available for periods of 30 s at each of three locations (pecking keys) during trials that lasted 90 s. In Experiment 2, food was available for periods of 15 min at each of four locations (pecking keys) during a 60-min trial. In both experiments, pigeons' key pecking was jointly controlled by the spatial and temporal cues. These data, and other recent experiments, suggest that animals learn relationships between temporal and spatial cues that predict stable patterns of food availability.
