Ch3: Elicited Behaviours and Classical Conditioning Flashcards
What is elicited behaviour?
behaviour drowned out by a preceding stimulus (responsive behaviour)
What is reflex?
relatively simple, automatic response to a stimulus
What is a startle response?
a defensive reaction to a sudden, unexpected stimulus
What is an orienting response?
when we automatically position ourselves to facilitate attending to a stimulus
What is a flexion response?
automatically jerk hand/foot away from a hot/sharp object that we have inadvertently contacted and the aformentioned startle reaction (fight/flight)
What is a reflex arc?
a neural structure underlying some reflexes that consists of a sensory neuron, an interneuron, and a motor neuron
What is a fixed action pattern?
a fixed sequence of responses elicited by a specific stimulus
What is a sign stimulus?
specific stimulus that elicits a fixed action pattern (species specific behaviours) - also called releaser
What is habituation?
a decrease in the strength of an elicited behaviour following repeated presentations of the eliciting stimulus
What is sensitisation?
an increase in the strength of an elicted behaviour following repeated presentations of the eliciting stimulus
What is short-term habituation?
the responce quickly decreases as a result of repeated stimulation and the ability to respond then quickly recovers in the absence of stimulation (continuous/narrowly spaced)
What is long-term habituation?
the response slowly decreases as a result of repeated stimulation and the ability to respond then slowly recovers in the absence of stimulation (gradual/paced)
What is dishabituation?
habituated responses can also reappear following the presentation of a seemingly irrelevant novel stimulus (INTERUPTION)
What factors can affect habituation and sensitisation?
intensity of stimulus, and evolutionary significance of the stimulus
Explain opponent process theory?
proposes that an emotional event elicits two competing processes: a - primary, directly elicited by event, & b - opponent - elicited by the a process and serves to counteract
