Summary of the Little Albert Experiment
The 9-month-old boy was exposed to Stimuli and observed, but showed no fear. He was exposed to a white rat and showed no fear but when the rat was presented again and Watson hit a metal pipe with a hammer, Albert cried. After the white rate was paired with the loud noise, Albert cried every time he saw the white rat
26
Ethical Considerations in the Little Albert Experiment (List 2)
- Informed consent may not have been obtained by Albert's mother - Withdrawal rights may not have been presented to Albert's mother - Albert was experiencing severe distress but yet the experiment was not stopped
27
Operant Conditioning as a Three-Phase Model
- Antecedent - Behaviour - Consequence
28
Operant Conditioning
Is a type of learning whereby the consequences of behaviour determine the likelihood that it will be performed again in the future
29
Antecedent
Is a Stimulus that comes before a specific behaviour
30
Behaviour
Is the voluntary action that occurs in the presence of the Antecedent Stimulus
31
Consequence
Is the environmental event that occurs immediately after the Behaviour
32
Observational Learning
Occurs when someone uses observation of a person's actions, and the consequences of those actions to guide their future actions
33
Social Learning
Refers to how the environment in which the learning occurs is important
34
Observational Learning Processes
- Attention - Retention - Reproduction - Motivation - Reinforcement
35
Attention
Is the first step in Observational Learning. It is the process that involves closely watching a model's behaviour and the consequences of their behaviour
36
Retention
Is the second step in Observational Learning. It involves the storage of the observed behaviour so the behaviour may be reproduced when needed
37
Reproduction
Is the third step in Observational Learning. It is the imitation of the behaviour that has already been attended to and retained in memory
38
Motivation
It is the fourth step in Observational Learning. It refers to how the learner must be motivated to reproduce the observed behaviour
39
Reinforcement (Observational Learning)
It is the fifth step in Observational Learning. Reinforcement influences the motivation to reproduce the observed behaviour and increases the likelihood of Reproduction
40
Reinforcement
It is when something is given to an individual to either strengthen their response to a behaviour or eliminate it completely
41
Types of Reinforcement
- Positive Reinforcement | - Negative Reinforcement
42
Positive Reinforcer
Is a Stimulus that is given to an individual that increases the likelihood of a desired response occurs by providing a rewarding consequence
43
Negative Reinforcer
Is any unpleasant Stimulus that, when removed increases the likelihood of a specific response occurring
44
Positive Reinforcement
Involves giving a Positive Reinforcer after the desired response has been made
45
Negative Reinforcement
Involves the removal of an unpleasant Stimulus, increasing the likelihood of a response being repeated, thereby strengthening the response
46
Memory
Is the processing, storage and retrieval of information acquired through learning
47
Fundamental Processes for Memory
- Encoding - Storage - Retrieval
48
Encoding
Is the conversion of incoming into a usable form so that it can be stored in memory

53
Structural Features of the Atkinson-Shiffrin Multi-Store Model of Memory
- Sensory Memory - Short-Term Memory (STM) - Long-Term (LTM)
54
Process of Memory
1. Sensory Information from the External Environment enters Sensory Memory. If it is not attended to, it is lost from Memory 2. If the Sensory Information is attended to, it gets transferred to Short-Term Memory where it gets rehearsed. It it is not rehearsed, it is lost from Short-Term Memory 3. If the Sensory Information is rehearsed in Short-Term Memory, it gets encoded into Long-Term Memory where some information may be lost over time. 4. If a person wants to retrieve the stored information, it gets brought from Long-Term Memory back into Short-Term Memory
55
Sensory Memory
Is the entry point of Memory in which incoming Sensory Stimuli are retained in their original form. Sensory Information remains in Sensory Memory just long enough for us to attend to and select the information to be transferred to Short-Term Memory for processing

62
Capacity of Short-Term Memory (STM)
7 ± 2 pieces of information
63
Duration of Short-Term Memory (STM)
About 18-20 seconds, but possibly up to 30 seconds
64

132
Brain Damage Associated with Alzheimer's Disease (AD)
The Medial Temporal Lobe, particularly the Hippocampus are most affected as up to 3/4 of the Neurons in this area may be lost, with the remaining Neurons often being left damaged
133
Brain Surgery: H.M.
H.M suffered from severe Epileptic Seizures and allowed surgeons to remove his Medial Temporal Lobe from both sides of his Brain. The surgery stopped his Seizures but H.M. was left with Anterograde Amnesia
134
Memory Impairments Associated with Damage to the Hippocampus
There is a disruption to the formation of Semantic and Episodic Memories and their transfer to the Cerebral Cortex for storage. This is because of the disruption to the consolidation of Short- Term Memories to Long-Term Memories
135
Memory Impairments Associated with Damage to the Amygdala
There is an inability to remember the emotion associated with the Long-Term Memories of an event. There is also an impaired ability to recognise facial expressions of emotions
136
Memory Impairments Associated with Damage to the Cerebral Cortex
Depending on which part of the Cerebral Cortex is damaged then that will affect the storage of a particular memory
137
Memory Impairments Associated with Damage to the Cerebellum
This depends on what age, Brain Damage has occurred in the Cerebellum. If at birth Brain Damage has occurred, relatively little effect takes place in Motor Ability. This is because of adaptive plasticity. Otherwise, there are problems with Motor Abilities
138
Retrieval Cue
Is any Stimulus that assists the process of locating and recovering information that is stored in Memory
139
Types of Retrieval Cues
- Context Dependent Cues | - State Dependent Cues
140
Context Dependent Cues
Are Environmental Cues from the specific setting where the learning has occurred, which can act as subsequent Retrieval Cues
141
Example of Context Dependent Cues
When you return to a place you haven't been to for a while and get filled with memories
142
State Dependent Cues
Are Internal Cues where you are in the same emotional state or setting as when you originally learnt the material
143
Example of State Dependent Cues
Getting angry creates an emotional state that triggers a range of past annoyances, such as a breakup
144
Serial Position Effect
Is the tendency to have better recall of the items at the start and end of the list, compared to the items in the middle of the list
145
Primary Effect
Is the better recall of items at the beginning of a list
146
Recency Effect
Is the better recall of items at the end of a list
147
Cause of the Serial Position Effect
The Serial Position Effect occurs because there are differences between Short-Term Memory and Long-Term Memory
