chapter 5 Flashcards
learning
the process of acquiring knowledge or skills resulting from experience
a relatively permanent change in behaviour due to the process of acquiring knowledge or skills, that occurs as a result of experience
NS, UCS, UCR, CR, CS
NS- neutral stimulus
UCS- unconditioned stimulus
UCR- unconditioned response
CR- conditioned response
CS- conditioned stimulus
- NS before conditioning has no relevant response
- NS becomes CS after conditioning
- UCR becomes CR after conditioning
*before conditioning UCS causes UCR
classical conditioning formula
+example
BEFORE:
-NS causes no relevant response
-UCS causes UCR
DURING:
- NS followed by UCS causes UCR
AFTER:
-CS leads to CR
example:
BEFORE:
- tiger plate (NS) causes no relevant response
- PBJs (UCS) causes dancing (UCR)
DURING:
- tiger plate (NS) followed by PBJs (UCS) causes dancing (UCR)
AFTER:
- tiger plate (CS) leads to dancing (CR)
behaviourist approaches
- an approach to learning that states that behaviours are learned through interactions with the environment.
-examples: classical conditioning and operant conditioning
conditioning
the learning process by which the behaviour of an organism becomes dependent on an event or stimulus occurring in its environment.
what is classical conditioning response
-the response is involuntary or reflexive
-it occurs automatically and unconsciously
-e.g. blinking in response to dust blowing in your eye on a windy day
PAVLOV’S PIONEERING CLASSICAL CONDITIONING RESEARCH
CLASSICAL CONDITIONING:
- a simple form of learning that occurs through repeated associations between two stimuli to produce a conditioned response.
STEP 1: dog → food presented → dog salivates
STEP 2: dog → metronome starts → no response
STEP 3 (multiple repeats): dog → metronome starts → food presented immediatley → dog salivates
STEP 4: dog → metronome starts → dog salivates
classical conditioning description
- classical conditioning can be described as a simple form of involuntary learning, which occurs through repeated associations of two different stimuli to produce a conditioned response.
THE THREE PHASE PROCESS OF CLASSICAL CONDITIONING
- before conditioning
- during conditioning
- after conditioning
BEFORE CONDITIONING
-no learning has taken place yet
-there is an unconditioned stimulus (UCS), which produces a naturally occurring autonomic response.
(the UCS is the presentation of food)
-the response to the UCS is called the unconditioned response (UCR) because it also doesn’t depend on any conditions. it is a naturally occurring autonomic response to the UCS.
(when the dog sees food it begins to salivate)
-there is also a neutral stimulus (NS)
(the sound of the metronome - the dog does not have a natural response to it)
DURING CONDITIONING
-learning occurs through association in which the two stimuli are associated or paired.
-the NS is usually presented and immediately followed by the UCS, or they are presented simultaneously.
(the metronome is started and the food is presented)
-This step is repeated multiple times, so that the two stimuli, the NS and UCS, become
associated or paired. This is called acquisition, the association of the NS with the UCS.
AFTER CONDITIONING
- NS becomes the CS
- through repeated association in the previous phase, the neutral stimulus (ticking metronome) on its own triggers the same UCR (salivation) as the unconditioned stimulus.
classical condtioning
three-phase process
BEFORE CONDITIONING
-An unconditioned stimulus (UCS) produces an unconditioned response (UCR).
-A neutral stimulus (NS) produces no response.
↓
DURING CONDITIONING
-The neutral stimulus (NS) is repeatedly presented immediately before the unconditioned stimulus (UCS), multiple times, and the UCS produces the unconditioned response (UCR).
↓
AFTER CONDITIONING
-The neutral stimulus (NS) is now the conditioned stimulus (CS) since on its own it now produces the unconditioned response which is therefore now the conditioned response (CR).
ethical concepts
INTEGRITY:
the commitment to searching for knowledge and understanding and the honest reporting of all sources of
information and results.
JUSTICE:
the moral obligation to ensure that competing claims are considered fairly, that there is no unfair burden on a particular group from an action, and that there is fair distribution and access to the benefits of an action.
RESPECT:
involves considering the value of living things, giving due regard, and considering the capacity of living things to make their own decisions.
BENEFICENCE & NON-MALEFICENCE:
the commitment to maximising benefits and minimising the risks and harms.
Ethical guidelines
CONFIDENTIALITY
Ensure the personal details of participants is not exposed.
VOLUNTARY PARTICIPATION
Participants do so freely and are not coerced into taking part
INFORMED CONSENT
Participants are informed of the nature of the study and any risks before agreeing to take part
WITHDRAWAL RIGHTS
Participants can withdraw from the study at any time without penalty
USE OF DECEPTION
Where the true nature of a study can not be disclosed, it must be explained as soon as possible
DEBRIEFING
Participants are told the true nature of the study, can ask questions and are told any findings or conclusions
operant conditioning
-a learning process in which the likelihood of a voluntary behaviour occurring is determined by its consequences.
-operant conditioning requires the learner to be active (voluntarily aware of the behaviour they are exhibiting in response to stimuli).
the three-phase model of operant conditioning
- ANTECEDENT- any environmental stimulus that triggers an action
- BEHAVIOUR- any action
- CONSEQUENCE- something that makes a behaviour more or less likely to occur again.
operant conditioning extra
during acquisition in operant conditioning, the voluntary behaviour is strengthened by association with a reinforcement or weakened by an association with a punishment.
