PSYC*2330 Chapter 8: Stimulus Control of Behaviour (MIDTERM 2) Flashcards
What is stimulus discrimination?
Differential responding in the presence of two or more stimuli
What is the opposite of stimulus discrimination?
Stimulus generalization
Responding to test stimuli that are different from the stimuli present during training is known as what?
Stimulus generalization
T or F: Even without stimulus discrimination, there can still be stimulus control.
False. Without stimulus discrimination, there is no stimulus control.
Responding often generalizes to other stimuli on the basis of what?
Their similarity to the training stimulus
What provides precise information about sensitivity of behaviour to systematic stimulus variations?
The stimulus generalization gradient
As a stimulus became increasingly different from the stimulus a bird was trained to peck to, did pecking go up or down?
Down
What does the stimulus generalization gradient measure?
Measures stimulus control
What does a steep generalization gradient indicate?
Strong control of behaviour by the stimulus
What does a flat generalization gradient indicate?
Weak or nonexistent stimulus control of behaviour
T or F: An organism’s sensory capacity sets a limit on what type of stimuli can control behaviour.
True
What type of studies are often used to determine what an organism is/is not able to perceive?
Studies of stimulus control
Interference with conditioning of a stimulus because of the simultaneous presence of another stimulus that is easier to condition is known as what?
Overshadowing
T or F: The availability of one type of cue (ex. a prominent landmark) may overshadow learning about other types of spatial information.
True
Is there a difference between males and females regarding whether landmark cues overshadow spatial cues?
Yes
