Discrimination learning with variable stimulus 'salience'
BACKGROUND In nature, sensory stimuli are organized in heterogeneous combinations. Salient items from these combinations 'stand-out' from their surroundings and determine what and how we learn. Yet, the relationship between varying stimulus salience and discrimination learning remains unclear. PRESENTATION OF THE HYPOTHESIS A rigorous formulation of the problem of discrimination learning shou...
متن کاملObservational learning in orangutan cultural transmission chains.
Field reports suggest that orangutans acquire local traditions by observing neighbouring conspecifics. However, there is little direct evidence of social learning to support this conclusion. The present study investigated whether orangutans would learn a novel foraging method through observation of a conspecific in a diffusion-chain paradigm testing for the spread of the behaviour. A foraging b...
متن کاملEvoked-potential changes following discrimination learning involving complex sounds.
OBJECTIVE Perceptual sensitivities are malleable via learning, even in adults. We trained adults to discriminate complex sounds (periodic, frequency-modulated sweep trains) using two different training procedures, and used psychoacoustic tests and evoked potential measures (the N1-P2 complex) to assess changes in both perceptual and neural sensitivities. METHODS Training took place either on ...
متن کاملThe Interactive Shaping of Social Learning in Transmission Chains
This study investigated the social transmission of memories and skills collected from a collaborative cooking task (raviolimaking) and across transmission chains. The transmission over three generations of pairs of participants occurred under two conditions. In the interactive condition, transmissions over generations occurred in face-to-face conversations, whereas in the non-interactive condit...
متن کاملCross-modal effects on learning: a seismic stimulus improves color discrimination learning in a jumping spider.
The production of multimodal signals during animal displays is extremely common, and the function of such complex signaling has received much attention. Currently, the most frequently explored hypotheses regarding the evolution and function of complex signaling focus on the signal and/or signaler, or the signaling environment, while much less attention has been placed on the receivers. However,...
