Betrayal Funnel
- Goffmann
- People we trust most – family and friends – conspire against us when we are unwell, reporting our actions to doctors and mental health professionals (called the ‘circuit of agents’) who run the decision-making process.
121
Role Stripping
- Goffmann
- The institutionalization process begins with a series of assaults on the recruit’s self.
- The process of stripping inmates of their identity involves such initiation rituals as trading personal clothes and belongings for hospital issue
122
Mortification
- Goffmann
- Mortification procedures that consist of a series of assaults on the inmate's self-image.
- At the end of mortification one becomes a ‘full member’ of the institution.
- Private, personal activities go on public display; he must request permission for even the most minor activities that were purely volitional on the “outside,” such as smoking, shaving, or going to the toilet.
- This is termed as civil death.
123
Privilege system
- Goffman
- The patient is then inserted into the lowest rung of an all- embracing privilege system.
- This system is based on the house rules.
- The privileges are usually reductions in the institution’s control over the patient’s life.
- Freedom is a token of reward.
124
Stages of the Moral Career
Goffman also described the ‘moral career’ of a mentally ill patient i.e. the process whereby a person with social ties, friends, and family in the community is institutionalized and converted into an inmate whose world is limited to his immediate hospital ambience (Peele et al. 1977).
1. Betrayal Funnel
2. Role Stripping
3. Mortification

128
A cat bit a young child when she attempted to feed it. After than, the girl remains afraid of approaching the animal. Describe the learning theory
Classical Conditioning
Classical conditioning explains some of the fear acquisitions seen during a child's development
129
Reciprocal Inhibition
- Wolpe
- If stimulus with desired response and stimulus with the undesired response are presented together repeatedly, then the incompatibility leads to a reduction in frequency of the undesired response.
- This is used in relaxation therapy for anxiety and in systematic desensitisation.
130
Shaping
- a.k.a. successive approximation
- Form of operant conditioning where a desirable behaviour pattern is learnt by the successive reinforcement of behaviours closer to the desired one.
- Shaping is used when the target behaviour is yet to appear (i.e. it is novel and does not exist already).
131
Chaining
- Reinforcing a series of related behaviours, each of which provides the cue for the next to obtain a reinforcer.
- Chaining is used when the target behaviour is already notable in some form but not in the fully formed sequence.
- An example is teaching a child to write his name. The shape of individual alphabets is first taught using reinforcers and forward chaining can be used to link each alphabet in the correct order, finally reinforcing the completed name.
132
Backward chaining
Starts at the end e.g. when making cupcakes, the child is first taught how to sprinkle over a finished cupcake, the next time icing the cake and sprinkling, the next time placing the prepared cake mixture into cupcake wrappers then icing then sprinkling etc.
133
Difference between shaping and chaining
Shaping is used when the target behaviour does not exist yet, some approximation of the behaviour is reinforced in steps (e.g. rat pressing lever)
(Shape does not exist)
Chaining is used when the target behaviour is already notable in some form but not in the fully formed sequence. (e.g. child writing name)
(Chain exists)
134
What type of learning is modelling?
Observational
135
Operant Conditioning
- Learning results from consequences of one’s actions – operations.
- The learning organism actively operates (instrumental) on the environment.
136
Classic Conditioning
- Learning takes place through repeated temporal association of two events.
- The learning organism is passive, respondent
(i. e. shows an innate, reflexive response such as salivation) but not instrumental (i.e. does not actively operate on its environment).
137
Insight Learning
- Kohler
- Diametrically opposite to associative learning and views learning as purely cognitive and not based on S-R mechanism - a sudden idea occurs and the solution is learnt.
138
Latent Learning
- Tolman
- Reinforcement may be necessary for a performance of learned response but not necessary for the learning itself to occur
- He inferred that rats can make cognitive maps of mazes – called place learning - which consists of cognitive expectations as to what comes next.
139
Discriminative Learning
- Process diametrically opposite to generalization
- Learned responses are made only to specific stimuli and not to other similar stimuli e.g. a child may be afraid of dogs but not all four-legged animals.
140
Premack’s principle
- a.k.a. Grandma’s rule
- High-frequency behaviour can be used to reinforce low- frequency behaviour e.g. “eat your greens and you can have dessert”.
- An existing high-frequency behaviour (eating dessert) is used to reward low-frequency behaviour (eating greens).
141
What type of reinforcement is least resistant to exctinction?
Continuous reinforcement
Every behaviour is followed by a reinforcer
142
What type of reinforcement takes the longest to enstablish?
Intermittent reinforcement
143
What type of reinforcement leads to highest rate of responding?
Fixed ratio reinforcement
More responses lead to more reinforcement, only short pauses occur after every response. Therefore, FR schedules lead to a higher rate of responding
144
What type of reinforcement leads to lowest rate of responding?
Fixed interval reinforcement
The organism knows the reinforcement will not be happening some reasonable time
145
Recognition in memory
Feeling of familiarity that accompanies return of stored material to consciousness
146
Retrospective falsification
Modifying memory in terms of attitudes and emotions
147
Jamais vu
- An experience that has been experienced before is not associated with feelings of familiarity.
- Both can occur in normal people, and also can occur in Temporal Lobe Epilepsy
148
Broadbent’s early selection filter theory
- Our ability to process information is capacity limited.
- A temporary buffer system receives all information and passes it to a selective filter.
- The selection is based on physical characteristics of the information – one source is selected and
others are rejected.
- Processing two different pieces of information will take longer and will be less efficient as
switching takes a substantial period of time.
149
Dichotic listening
- Refers to feeding one message into the left ear and a different message simultaneously into the right ear.
- Participants have to repeat one of the messages aloud. This process is called Shadowing (first used by Cherry).
- This is a method to study selective attention.
- Divided attention can be tested using a dual-task technique whereby the individual is asked to attend and respond to both or all incoming messages.
150
Cocktail party effect
- It is a concept related to selective attention.
- It is a term used in early attention research ‘to describe the ability of people to be able to switch their attention rapidly to a non- processed message’.
- The cocktail party effect shows that certain types of stimuli can elicit switching between messages e.g. the physical location of the speaker, the pitch of the voice or the use of familiar stimuli such as the listener’s name. (Lunch-queue effect)
151
Triesman’s attenuation theory
- Treisman (1964)
- Physical characteristics and semantic relevance (meaning) are used to select one message for full processing while other messages are given partial processing.
152
James-Lange theory of emotions
- Perception of a stimulus leads to bodily (skeletal and visceral) changes.
- The peripheral responses send feedback to the cortex via thalamus leading to the perception of the emotion.
(James-Lange - Body)
153
Cannon-Bard theory
- On the perception of a stimulus, thalamus coordinates signals to cortex leading to a conscious experience and simultaneously sends signals to hypothalamus leading to physiological changes.
- The thalamus is considered to be cardinal in the emotional appraisal.
(Cannon-Bard - Thamalus)
154
Schachter-Singer labelling theory
- On the perception of a stimulus, both physiological changes and a conscious experience of general arousal take place simultaneously.
- This generic arousal is then interpreted to either positive or negative and labelled appropriately according to the situational cues.
This is also called jukebox theory or two-factor theory.
- If an appropriate label is not found, by default, negative appreciation of arousal occurs (e.g. ‘dysphoria’ when experiencing boredom).
(Schachter-Singer- Simultaneous SSS)

Lazarus cognitive appraisal theory
- States that appraisal precedes affective reaction – hence affective primacy cannot be supported.
- Cognitive appraisal refers to the immediate, intuitive, personal evaluations of a situation that gives an idea of how the individual subjectively experiences their environment.
- Roseman and Scherer propose eight cognitive appraisal dimensions to distinguish emotional understanding, rather than the traditional two (pleasantness and arousal).
- A third group of theorists suggest that each emotion is categorised by a unique pattern of cognitive appraisals.
156
Group polarisation
A group discussion process can strengthen average individual inclinations and polarise the group in the direction where most individuals were heading already
157
Risky Shift
The group can make more risky decisions than what an individual him/herself can.
158
Groupthink
While making extreme decisions, the desire to agree with other members of a group can override rational judgment applicable in individual decision-making
159
Conformity
- A process where no explicit requirement is made to do a certain task, but peer influence, and the need for acceptance pushes one to carry out the task.
- e.g. Individual agrees with the group despite holding a different personal view
160
Pluralistic ignorance
- This refers to members of a crowd looking at each other for signs of distress but remaining calm themselves, leading to misappraisal of the situation being safe leading to lack of intervention.
- Bystander competence is usually not required for intervention except in ambiguous situations where technical help is required e.g. blood at the scene.
161
Festinger’s deindividuation theory
- People in-group context act uncharacteristically more aggressive as a sense of identity and belongingness and diffusion of responsibility occurs in groups.
- Similarly, uniforms can reduce individuality, promoting expression of aggression (hence its use in Police and military forces).
- But deindividuation does not always cause aggression.
162
Obedience
- Conditions where the individual is explicitly asked to do a task, and this instruction comes from an authority.
163
Social Loafing
- Ringelmann’s effect
- It is seen in games such as tug-of-war and in clapping hands after a performance.
- The larger a group is, the less the individual performance - as one thinks the others will do the job
(Loafing off others)
164
Legitimate Power
Based on the perception that someone has the right to prescribe behaviour due to election or appointment to a position of responsibility
165
Autocratic Leadership
- Leader’s decision-making occurs without consultation from the others and causes the most discontent.
- It works if no need for input on decision i.e. that motivation would not be affected by not being consulted.
(autocratic - authoritarian)
166
Coercive Power
The perceived ability to punish those who not conform with your ideas or demands
167
Referent Power
Through association with others who possess power
168
Informational Power
Based on controlling the information
169
Democratic Leadership
- Leader’s decision-making involves others though the decision may ultimately made by the leader having facilitated group discussion and discussed opinions.
- It is a well-regarded process but can be time-consuming.
170
Reward Power
Based on the perceived ability to give positive consequences or remove negative ones
171
Expert Power
Based on having distinctive knowledge, expertness, ability or skills
172
Procedural Memory
- Made of procedural memory for skills and habits, priming, classical conditioning and non- associative learning.
- This cannot be consciously inspected.
- This is not affected by an organic amnesia of hippocampal origin.
173
Working Memory
- Working memory allows cognitive processes to be performed on data that is briefly stored in short-term memory.
- Increasingly used to describe a large part of what was called as STM in the past.
174
Anterograde Memory
New learning
175
Declarative Memory
- Type of long term memory
| - Explicit – includes semantic and episodic memory
176
Episodic Memory
Autobiographical, self-focused, spatio-temporal memory
177
Infantile Amnesia
The average age of the earliest retrieved memory is 3.5 years. There is a total lack of memories for events occurring during the first few years of life, and there is a variable degree of amnesia for events that occurred in the first 2 to 5 years.
178
Retrograde Memory
The ability to recall events that occurred or information that was acquired prior to a particular point in time, often the onset of illness or physical damage such as brain injury.
179
Semantic Memory
Category of long-term memory that involves the recollection of ideas, concepts and facts commonly regarded as general knowledge
