Abstract

1. 1. Exploration of a strange object by Lebistes during a 20-min presentation increased with increased experience of the surroundings, for sixteen naive fish. The peak of investigation occurred sooner in fish which had more experience of their surroundings. There was significantly more exploration when a fish had 4 or more days' experience of the surroundings than when it had 3 days' experience or less.2. 2. For the first presentation of a strange object, experience of the surroundings had no effect on time to first approach to the object.3. 3. When the object was presented for the second time 24 hr after the first presentation, there was an increase in exploration by fish with experience of surroundings of 1 to 3 days, but a decrease in exploration by fish with experience of the surroundings of more than 5 days.4. 4. For an animal with some experience of the type of object and of the object being presented, and for which the previous situation had lasted for more than 24 hr, experience of surroundings had a significant effect on the length of bouts of exploration.5. 5. For an animal with experience of its surroundings and of the object being presented, the duration of the previous situation had a slight (positive) effect on the length of bouts of exploration.6. 6. An animal with a given amount of experience of the object presented investigated the object less and in shorter bouts the more experience it had of such objects.7. 7. None of the experience variables considered had any effect on measures of avoidance, although a significant difference in avoidance can be demonstrated in experienced fish.
