Chapter 5 Notes 5-1 Learning About Stimuli Why do constant sounds seem to disappear? Our information-processing systems are unable to pay attention to every sight and sound - they would become overloaded. Instead we tune in to certain kinds of events o Loud sounds, special tastes, pain o Novel stimuli - things we have not experienced before Our response unchanging stimuli decreases over time - this aspect of adaptation is a simple form of learning called habituation Can occur in relation to sights, sounds, smells, tastes, or touches Especially important for adapting to initially startling but harmless events such as the repeated popping of balloons Occurs in some degree to all kinds of stimuli in all kinds of animals Dishabituation - the reappearance of your original response when a stimulus changes Ex. You may become aware again of the ticking of a grandfather clock after the hourly chime has sounded because now, something in your environment has changed. A second simple form of learning is sensitization Appears as an increase in responsiveness to stimulus. Occurs when people and animals show exaggerated responses to unexpected, potentially threatening sights or sounds o Especially during periods of emotional arousal Ex. Things are more frightening at night or in the dark or in a spooky house at night Habituation and sensitization provide organisms with a useful way to adapt to their environments Result from a single stimulus, instead of association of one stimulus with another o For this reason, they are referred to as nonassociative learning We have to consider forms of learning that involve the associations between stimuli, as well as between stimuli and responses Ex.
