Abstract

The three objectives of the project are directed at understanding the ability of domestic pigs in social exploitation of information held by others: (1) To find out if pigs can learn to deceive a competitor in foraging task, we use an informed forager task previously adapted for pigs by ourselves. We have already shown that pigs can detect and exploit superior knowledge of competitors, and that they discriminate and remember locations of food rewards of differing value. Now we follow up previous evidence suggestive if pigs¿ ability to deceive competitors even without opportunity to acquire tactics by reinforcement, using a new experiment in which competitors differ in rank and rewards differ in quality. (2) To investigate the ability of pigs to learn motor actions by observation, we use a manipulable device that can be set to several modes of food delivery. Imitative learning will be studied in 3 stages: learning and remembering simple actions after a delay, to focus on symbolic representation of actions; learning daily-changed settings for food delivery, to detect the potential of motor imitation to aid everyday foraging; and acquiring a complex sequence of movements, as a first step towards acquisition of novel complex skills by observational (program-level) learning; (3) To investigate factors affecting the social transmission of information through groups of pigs, the same kind of device will be used to introduce novel modes of food extraction into several different groups of pigs, focusing on the effect of demonstrator pigs on rate of spread. We will vary the presence and number of demonstrators, and the effect of their dominance status compared to that of learners. Joint with BB/C510559/1
