Chapter 3: Habituation, Sensitisation & Familiarisation - Learning about Repeated Events Flashcards
What is habituation?
the decrease in the strength of the response with repeated exposure to a particular eliciting stimuli
Does elicited response, particularly a simple reflex response, automatically occur the same way each time the eliciting stimulus is presented/
NO
Behaviour is not invariant and can be modified
What was concluded about visual attention in human infants?
Babies have longer attention spans when staring at the more complex/interesting stimuli
What did visual attention in human infants measure?
Measured how long infants spent looking at a visual stimulus during successive trials
What is acoustic startle reflex?
a defensive response (such as jumping or freezing) to a startling stimulus )such as a loud noise)
What is orienting response?
an organism’s innate reaction to a novel stimulus
With repeated starting stimuli the startle response will?
progressively go down; however, there still will be a response
What is spontaneous recovery?
wait for a period of time before presenting the starting stimuli again, startle response returns
What is an important feature of habituation?
is that habituation to one event does not cause habituation to every other stimuli in the same sensory modality
What is dishabituation?
This renewal of responding after a new stimulus has be presented
How rapidly a response habituates and how long the decrease in responding lasts depend on several factors, what are they?
how startling the stimulus is, the number of times experiences, and the length of time between repeated exposures
What is spontaneous recovery?
a tumulus-evoked response that has been weakened by habituation increases in strength or reappears after a period of no stimulus presentation
What is sensitisation?
a phenomenon in which experiences with an arousing stimulus lead to stronger responses to a later stimulus
one way that researcher can study sensitisation experimental in humans is by measuring?
electrodermal activity (EDA)
What is electrodermal activity (EDA)?
a measure of changes in the skin’s electrical conductivity that are caused by fluctuation in the activity of the peripheral nervous system
