Basic Psychology Flashcards
Definition of Non-associative learning
Simple form of learning where only a single event is used
Types of non-associative learning
Habituation
Sensitization
Pseudo-conditioning
What is habituation?
Repeated stimulation leads to reduction in response over time
What is sensitization?
Increase in response to stimulus due to repeated presentations of that stimulus
What is pseudoconditiong/cross-sensitization?
Emergence of a response to a previously neutral stimulus due to exposure to a different but more powerful stimulus
What type of learning is cross-sensitization?
Non-associative learning
What is associative learning?
Learning through the association of two events
Types of associative learning
Classic conditioning
Operant conditioning
Social learning theory
What is classical conditioning?
Learning through repeated pairing of a neutral conditioned stimulus with an unconditioned stimulus which evokes an unconditioned response. Eventually, the neutral stimulus will evoke the desired response; the conditioned response.
What is operant conditioning?
Learning from the consequence of ones actions.
In which type of associative learning is the organism instrumental?
Operant conditioning
Social learning theory
What is social learning theory?
Combination of classic and operant conditioning, as well as cognitive processes and social interactions
What is the conditioned response in classical conditioning?
The desired response once it is evoked by the neutral stimulus.
What is the name of the association between the conditioned stimulus and the unconditioned response?
Acquisition
What is acquisition in classical conditioning?
The association between the conditioned stimulus and the unconditioned response.
What is trace conditioning?
When the conditioned response is presented and removed before the unconditioned stimulus is presented.
What is the optimum delay for trace conditioning?
0.5ms
What is temporal contiguity in classical conditioning?
The time between stimulus and response.
What is counter conditioning?
When a previously conditioned response is replaced by a new, more desirable response.
What is latent inhibition in classical conditioning?
Where there is a delay in learning the association between the unconditioned stimulus and the conditioned stimulus due to previous exposure of an isolated presentation of the conditioned stimulus
What is Premack’s principle?
That high-frequency behaviour can be used to reinforce low-frequency behaviour.
What is aversive conditioning?
Where punishment is used to reduce the frequency of target behaviour
What type of conditioning is this:
The use of disulfram to reduce alcohol intake
Operant conditioning
Punishment
Aversive conditioning
What is covert reinforcement?
Using an imagined positive event to reinforce behaviour.
What is covert sensitization?
Using an imagined negative event to reduce the frequency of undesired behaviour.
What is reciprocal inhibition?
When a stimulus with a desired response and a stimulus with an undesired response are presented together repeatedly, this results in a reduction in the frequency of the undesired response.
What is Bandura’s social learning theory?
That people can learn behaviour by observing others behaviours and their outcomes.
What are the cognitive processes during social learning?
- Attention to observed behaviour
- Visual image and semantic encoding of observed behaviour memory
- Memory permanence via retention and rehearsal
- Motor copying of behaviour and imitative reproduction
- Motivation to act
What is Gagne’s hierarchy of learning?

- Operant conditioning
- Chaining
- Verbal association
- Discrimination learning
- Concept learning
- Rule learning

What does Gestalt’s law of perceptual organisation include?
Proximity Closure Continuity Similarity Common fate

Incompletely closed figures are perceived as fully closed
What does continuity mean in Gestalt’s law of perceptual organisation?
Continuous items are perceived as one
What does similarity mean in Gestalt’s law of perceptual organisation?

What is autokiniesis?
The phenomenon that if light is shown from a small, dim and fixed light source for an extended period of time in a dark room it will appear as if the light is moving.
What is the phi phenomenon?
When a false perception of motion is produced by a succession of still images shown with fixed time interval rapidly.
What type of theory is Gestalt’s theory?
Bottom-up theory
What do bottom-up theories in visual & auditory perception suggest?
That perception is purely data driven and directly starts with the optic array. Piercing together of basic elements of this data leads to more complex systems.
What does a top-down theory suggest?
That retinal images cannot explain complex and fully formed perceptions, and that perception is defined as a process of using information known already to formulate/test a hypothesis.
What is a perceptual set?
The readiness to perceive selected features as an object (related to motivation, hunger, emotion etc)
Define an illusion
When a physical object is perceived but appears different from what it really is
Define a hallucination
When an object is perceived in the absence of any corresponding object in the real world.

What is capacity/divided attention?
The upper limit of the amount of processing that can be performed on incoming information at any on time.
What is dichotic listening?
Feeding one message into the left ear and another into the right, and asking the person to repeat only one of the messages.
What does Broadbent’s early selection filter theory suggest?
- Our ability to process information is capacity limited
- A temporary buffer system receives all information and passes it to a selective filter.
- Selection is based on physical characteristics of information - one source is selected and others are rejected.
- Processing two different pieces of information will take longer and will be less efficient.
What does Triesman’s attenuation theory suggest?
That physical characteristics and semantic relevance and used to select one message for full processing while others are given partial processing.
What does Deutsch-Norman late selection filter model/pertinence model suggest?
That filtering only occurs once all inputs are analysed at a higher level.
What is pigeon-holding?
When filtering is done based on categorization rather than physical characteristics.

In what type of amnesia are the last words recalled better than the first in a list?
Organic anterograde amnesia
What is the problem in organic anterograde amnesia?
Difficulty in transferring information from STM to LTM, and retrieval from LTM
What is reconstruction?
Recollection of past experiences based on certain cues
What is the decay theory?
That neural engrams breakdown with time, thereby disuse with time causes forgetting.

Mood-state dependent retrieval
What is a schema?
Organized set of facts, to help elaborate and reconstruct memory at test.
