Flashcards in Biological Dispositions in Learning Deck (22):

What is preparedness?

innate tendency to more easily learn certain types of behaviour


What is taste aversion conditioning?

food item that has been paired with illness becomes conditioned aversive stimulus


How is taste aversion conditioning different from other forms of CC?

formation of associations after long delays, one trial conditioning, specificity of associations


What is latent inhibition?

more likely to associate a relatively novel item with sickness than a familiar one


What is overshadowing?

more likely to develop aversion to stronger tasting food item than milder tasting food


Rats will more readily learn to __ than __

press lever to obtain food, avoid shock


What did Bolles study which looked at biological predispositions for avoidance responces

Species specific defence reactions


What is instinctive drift?

an instance of classical conditioning in which a genetically based, fixed action pattern gradually emerges and displaces the behaviour that is being operantly conditioned (interferes)


What is sign tracking?

an organism approaches a stimulus that signals the presentation of an appetitive event


What is autoshaping?

type of sign tracking in which a pigeon comes to automatically peck at a key because the key light has been associated with contingent delivery of food


What is negative automaintenance?

sign tracking persists despite the resultant loss of a reinforcer


What is adjunctive behaviour?

excessive pattern of behaviour that emerges as a bi-product of an intermittent schedule of reinforcement for some other behaviour (or schedule induced behaviour)


What reinforcement schedules are commonly used when developing adjunctive behaviours?

fixed interval or fixed time


Adjunctive behaviour is affected by levels of deprivation. __ deprivation, __ adjunctive behaviour is as a bi-product

greater, stronger


What is the optimal interval time between reinforcers for the development of adjunctive behaviours

1-3 minutes


When do adjunctive behaviours usually occur?

In the period immediately after an intermittent reinforcer is consumed (interreinforcement intervals)


What is a displacement activity?

an apparently irrelevant activity sometimes displayed by animals when confronted by conflict of thwarted from attaining a goal


What is good about displacement activity?`

provides more diversified range of behaviours in particular setting, help animals remain in situation where a significant reinforcer may actually become available


What is activity anorexia?

an abnormally high level of activity and low level of food intake generated by exposure to a time restricted schedule of feeding


In activity anorexia, which behaviour is considered the adjunctive behaviour?

exercise/physical activity


What are two underlying mechanisms believed to be involved with activity anorexia

addiction to endorphin high, survival value (food supply)


What is the behaviour Systems theory?

an animal's behaviour is organised into certain innate systems, with each system becoming activated in relevant situations (3 systems - general, focused, handle/consumption
