Basic Psychology Flashcards
The most important and common bedside test that is used in demonstrating age-associated memory impairment would be;
Select one:
1. Delayed recall
2. Orientation to time and place
3. Immediate recall
4. Naming objects
5. Attention and calculation
Delayed recall
Approximately 40% of individuals aged 65 and over show AAMI. Cognitive testing has demonstrated that
memory for non-verbal material seems to be more affected by aging than memory for verbal material, and delayed recall is more affected than immediate recall. Here the subject is given a list of 20 words and then ask him or her to recall as many as possible in 20 minutes. Finally, the score is compared with standardised scores for the given age.
Which conditioning is involved in the aetiology of both agoraphobia and of obsessional rituals?
Select one:
1. Classical conditioning
2. Forced conditioning
3. Backward conditioning
4. Operant conditioning
5. Avoidance conditioning
Avoidance conditioning
The term aversive conditioning refers to situations in which behavior is motivated by the threat of an
unpleasant stimulus. There are two main categories of behavior under aversive control: avoidance behavior
and escape behavior. Escape conditioning occurs when the animal learns to perform an operant to
terminate an ongoing, aversive stimulus. It is a “get me out of here” or “shut this off” reaction, aimed at
escape from pain. The behavior that produces escape is negatively reinforced (reinforced by the elimination
of the unpleasant stimulus). For example, the jump of a rat from electrified platform onto a bowl of water is
an escape behavior. Escape conditioning is converted into avoidance conditioning by giving a signal before
the aversive stimulus starts. If the animal receives a cue or signal that an aversive stimulus is coming, then
after one or two occurrences of the punishing stimulus the cue will trigger an avoidance behavior. This kind
of learning occurs quickly and is very durable. For example, if you sounded a tone before you electrified the platform, after one or two trials the rat would respond to the tone by jumping into the water. It would not wait for the shock. Avoidance behaviors are very persistent even when there is no longer anything to avoid. The reason is that as a result of an avoidance reaction, one never experiences the aversive stimulus. But this serves as a negative reinforcement, providing a sense of relief. Because of this, avoidance behavior is self reinforcing.
Mr. Z visited his doctor and following his visit he remembered the first few things they had been told better than subsequent information. What is the name of this tendency?
Select one:
1. Referred effect
2. Primary effect
3. Recency effect
4. Primacy effect
5. Preliminary effect
Primacy effect
Serial position effect: While memorising and recollecting a list of words both Primacy and Recency effects are seen. In free recall experiments, materials that were presented first are better recalled than items in the middle, which is called as primacy effect. Also items that are presented towards the end of the list are more likely to be remembered, which is called as Recency effect. Primacy is supposed to be due to LTM as consolidation has occurred in the sufficient time between learning the first word and testing recall. Recency is due to STM where last heard words are freshly retained.
Which of the following best describes Ribot’s law in memory disturbances?
Select one:
1. In organic amnesia remote memory content is lost before recent content.
2. In organic amnesia recent memory content is lost before remote content.
3. In dissociative amnesia anterograde amnesia is dense.
4. In organic amnesia anterograde amnesia cannot occur without retrograde loss.
5. In dissociative amnesia recent memory content is lost before remote content.
In organic amnesia recent memory content is lost before remote content.
Ribot’s Law refers to progressive amnesia as a temporal gradient going from the most recent to the oldest memories
Raven’s progressive matrices test is used to assess
Select one:
1. Premorbid intelligence
2. Frontal lobe functions
3. General intellectual ability
4. Visuospatial ability
5. Attentional bias
General intellectual ability
Raven’s Progressive Matrices (often referred to simply as Raven’s Matrices) are multiple-choice intelligence
tests of abstract reasoning that provide culturally unbiased IQ estimates. Rey Osterrieth test comprises of copying a complex figure initially and then reproducing it from immediate and delayed recall that tests both visual memory and constructional ability
Which one among the following statements regarding needs and motivation is incorrect?
Select one:
1. According to Yerkes-Dodson curve, there is an inverted U-shaped relationship between
arousal (motivation) and performance level
2. According to Canon’s homeostatic theory, changes in homeostatic system triggers
processes aimed at restoration of system
3. According to Maslow’s hierarchy of needs, Needs at the previous level need to be
satisfied before one can progress to the next level
4. According to Drive reduction theory, motivation of behaviour is to decrease the arousal
associated with basic drives
5. In Maslow’s hierarchy of needs, cognitive needs precede esteem needs
In Maslow’s hierarchy of needs, cognitive needs precede esteem needs
Maslow’s hierarchy of needs: Maslow is best known for his hierarchy of needs in which he proposed that
basic needs such as the physiological needs of hunger and thirst must be satisfied before the higher needs
(such as esteem and self actualisation) can be achieved. Physiological needs, safety needs, Love and
belongingness needs, esteem needs, Cognitive needs, Aesthetic needs and self-actualisation needs.
Cannon postulated the homeostatic drive theory. According to this theory, changes in homeostatic system triggers processes aimed at restoration of system. Basic needs (biological needs), being self-regulating, function homeostatically. According to Yerkes-Dodson curve, there is an inverted U-shaped relationship between arousal (motivation) and performance level. As the level of emotional arousal increases, so does performance efficiency, to an optimum level. As the emotional arousal increases above this point, performance starts to deteriorate The drive reduction theory by Hull: According to this theory, motivation of behaviour is to decrease the arousal associated with basic drives e.g. thirst but doesn’t explain curiosity
motives and the theory is generally rejected.
Compulsions provide short-term relief of obsessional anxiety. The learning principle operating here is
Select one:
1 Positive reinforcement
2. Negative reinforcement
3. Reciprocal inhibition
4. Punishment
5. Reward orientation
Negative reinforcement
Compulsions provide short-term relief of obsessional anxiety via negative reinforcement. When practicing
compulsive rituals, anxiety is acutely reduced. This provides a reinforcement to practice the compulsions
repeatedly. In other words the termination of the aversive anxiety cued by obsessions, increases or stamps in the compulsive behaviour that removed the anxiety, without addressing the core of obsessions.
Learned helplessness has been invoked to explain the aetiology of;
Select one:
1. Obsessive compulsive disorders
2. Psychosomatic disorders
3. Anxiety disorders
4. Psychotic disorders
5. Depressive disorders
Depressive disorders
Learned helplessness: This is the tendency of an organism to give up trying to avoid or escape from an
unpleasant stimulus because in the past all their attempts at so doing had been frustrated. Dogs were given electric shocks and prevented from escaping but after repeated shocks the dogs would no longer try to
escape, even when a fairly obvious means of escape was made available and this was invoked to explain
the etiology of depression.
Tip of the tongue state is a well investigated example of
Select one:
1. Context dependent memory
2. Blocking
3. Encoding failure
4. Failure of prospective memory
5. State dependent memory
Blocking
Sometimes people may have the experience that we know the answer we are seeking but cannot quite find
it and this feeling is known as the tip-of-the-tongue phenomenon, also abbreviated as TOT phenomenon.
This is a well investigated example of Blocking, which is one of the ‘retrieval failure’ theories of forgetting.
Blocking is said to occur when the subjects are unable to access information that they know exists in their
memory despite great efforts at recalling even in the presence of retrieval cues. TOT states may last for few
seconds or for a few days.
A reinforced operant response weakens when the reinforcement is ceased. This is called
Select one:
1. Stimulus decoupling
2. Stimulus sensitisation
3. Extinction
4. Stimulus discrimination
5. Stimulus incubation
Extinction
Extinction is typically studied within the Pavlovian fear conditioning framework in which extinction refers to
the reduction in a conditioned response (CR; e.g., fear response/freezing) when a conditioned stimulus
(CS; e.g., neutral stimulus/light or tone) is repeatedly presented in the absence of the unconditioned
stimulus (US; e.g., foot shock/loud noise) with which it has been previously paired.
Which of the following is correct concerning sensory memory?. Sensory memory has
Select one:
1. Small capacity but memories are unprocessed and of long duration (>0.5s)
2. Small capacity and memories are unprocessed and of very short duration (<0.5s)
3. Large capacity but memories are unprocessed and of very short duration (<0.5s)
4. Large capacity but memories are unprocessed and of long duration (>0.5s)
5. Large capacity but memories are processed and of very short duration (<0.5s)
Large capacity but memories are unprocessed and of very short duration
Sensory memory retains the transient impression of a sensory stimulus even after the stimulus itself has
ceased. Imagine, seeing an object. Even after the object has disappeared, it may still be vivid in your
memory. It has a large capacity, but objects are unprocessed.
Timeout refers to a technique that is aimed at
Select one:
1. Generalising a learnt behaviour
2. Reducing desirable behaviour
3. Increasing unwanted behaviour
4. Learning new behaviour
5. Reducing unwanted behaviour
Reducing unwanted behaviour
Time out or loss of privileges are used as negative reinforcement strategies to reduce unwanted behaviours in children.
A family has got a new dog. A 3-year-old child in the family is afraid of dogs and would stay in the same
room with the dog only if he could sit on his mother’s lap and had his favourite ice cream. Select the
learning theory principle employed here
Select one:
1. Reciprocal inhibition
2. Avoidance learning
3. Classical conditioning
4. Operant conditioning
5. Extinction
Reciprocal inhibition
This scenario is an example of reciprocal inhibition (Wolpe). This principle states that two opposing
emotions cannot stay together for long time - one will reciprocally inhibit the other. Comfort with mother and
ice-cream conflicts with discomfort produced by the dog - eventually the dog stops eliciting discomfort. This
principle underlies most psychological therapies for anxiety disorders.
The modification of memories in terms of one’s general attitude is called
Select one:
1. False memory syndrome
2. Semantic memory
3. Repressed memory
4. Flashbulb memory
5. Retrospective falsification
Retrospective falsification
Unconscious distortion of memory, as dictated by one’s present psychological needs, is called as
Retrospective Falsification. People who retrospectively falsify a story also tend to embellish the positive and
delete the negative aspects of the situation. Example: During marital conflicts argument ensues over the
partners’ differing recollections of their original verbal exchanges.
A group of subjects studying molecular biology were asked to solve Multiple choice questions. What mode
of retrieval is this?
Select one:
1. Recall
2. Reintegration
3. Reconstruction
4. Re-learning
5. Recognition
Recognition
Modes of retrieval (LTM transferred onto STM) are through
1.Recognition (solving MCQs)
2.Recall (actively searching and reproducing), 3.Reintegration/reconstruction (recollection of past experiences based on certain cues). An eyewitness testimony is a reconstructive memory, which is a mode of retrieval from long term memory. However, a reconstructive memory of events as in eyewitness testimony is affected by the type of questioning asked to elicit the memory.
Which one among the following is a secondary emotion?
Select one:
1. Fear
2. Joy
3. Love
4. Sadness
5. Anger
Love
Primary emotions-anger, disgust, joy, anticipation, fear, acceptance, surprise and sadness (classified by
Plutchik) .
Secondary emotions include love, contempt, submission and disappointment.
A dysthymic patient vividly recalled the events that occurred when he was depressed but poorly recalled the events that occurred during happier times. This is an example of
Select one:
1. Failure of prospective memory
2. Context dependent memory
3. Blocking
4. Encoding failure
5. State dependent memory
State dependent memory
State-dependent memory; It is a phenomenon in which the retrieval cue at the time of encoding information is one’s internal state rather than the external context. These might be psychological or physiological (being nervous, drunk, etc.) e.g. a depressed patient will normally tend to focus on events that happened during periods of depression and will have difficulty recalling more positive moments. The other common observation is seen in alcoholics, who when sober cannot recall what occurred when drunk, only to remember again next time when he/she drink too much.
A 45-year-old man was admitted to the acquired brain injury unit with severe memory impairment. Which of
the common clinical tests can be used to test his immediate memory?
Select one:
1. Recall of last meal
2. Recall of distant personal events
3. Recall of items after 5 minutes
4. Recall of recent topics in news
5. Digit span
Digit span
The terms used in psychology and psychiatry are somewhat different which could lead to some confusion.
The terms used in psychology are short term memory (immediate memory in psychiatry) and long-term
memory (recent memory and remote memory in psychiatry). Digit span tests immediate memory (STM).
Recollection of a name and an address after 5 minutes is seen as a test of recent memory (which, in fact, is
a part of LTM and should not be considered as a test of STM).
Mr. Z was admitted to a neuropsychiatric unit with a diagnosis of an amnesic syndrome. He was referred to
psychology for psychometric testing. Which of the following would be unimpaired in formal testing?
Select one:
1. Episodic memory of recent past
2. Anterograde memory
3. New learning
4. Immediate memory
5. Delayed recall
Immediate memory
Various disorders can give rise to amnesic syndromes (E.g. hypoxia, herpes encephalitis) and the features
would include
1. Unimpaired immediate memory.
2. The presence of anterograde amnesia- inability to
acquire new information (impaired delayed recall)
3. The presence of retrograde amnesia of variable extent and severity
4. Unimpaired global intellectual abilities
5. Unimpaired implicit memory
Which of the following theorists proposed six basic emotions?
Select one:
1. Ekman
2. Lorenz
3. Cannon and Bard
4. James and Lange
5. Ainsworth
Ekman
According to Paul Ekman, the six basic emotions are sadness, happiness, anger, fear, disgust, and surprise. These emotions combine in different ways to form other emotions, including compassion, boredom, embarrassment, rage, hunger, and more.
According to Ebbinghaus curve, there is a sharp drop in forgetting over
Select one:
1. First eighteen hours
2. First seven days
3. First twenty four hours
4. First one month
5. First nine hours
First nine hours
Hermann Ebbinghaus plotted the forgetting curve by plotting proportion of words retained in memory
against time. The curve shows a sharp drop over the first nine hours and particularly during the first hour.
After nine hours, the rate of forgetting slows and declines little thereafter, even after the lapse of 31 days.
The main findings from his and other studies are; Forgetting is maximum in the first few hours and the rate of forgetting gets less with time. Forgetting is never complete and some information is retained over longer periods of time, even for life. Recalling the material during the test period increases the probability of remembering items or events. Continuous motor skills such as cycling and swimming etc show no forgetting at all. But discrete motors kills such as typing are lost more quickly.
Which one among the following is not one of the Gestalt principles of perception?
Select one:
1. Similarity
2. Continuity
3. Closure
4. Familiarity
5. Proximity
Familiarity
The Gestalt principles of perception would include proximity, closure, similarity, continuity and symmetry.
According to Gestalt principles, we tend to perceive whole objects rather than parts. The perceptual systemin our brains employs these principles to enable us perceive unified forms rather than simple collections of unconnected images.
The principle of combining separate pieces of information into one meaningful combination is called
Select one:
1. Encoding
2. Primacy effect
3. Chunking
4. Sensory storage
5. Recency effect
Chunking
Chunking is a method of increasing the capacity of short-term memory by combining units or information
(usually numbers) into chunks. By doing so, impressive feats of memory can result. For example the
numbers 1,5,2,3,5.2,5,8,5,3,7,8 would normally overload our short term memory but if they are arranged into chunks 152, 352, 585, 378, they become a lot more manageable. The capacity of STM according to Miller is 7+/- 2, as evident while testing digit span. By chunking, larger information could be sorted into 7+/-2 items and effectively stored.
The storage of information in pure form without specification of time and place is called
Select one:
1. Semantic memory
2. Episodic memory
3. Absolute memory
4. Schemas
5. Declarative memory
Semantic memory
Semantic memory is an important part of declarative memory and is concerned with remembering facts,
ideas and concepts. It refers to what is known rather than when and how the knowledge was acquired. Eg
in answering a question ‘what is the capital of Scotland’, one is using semantic memory. Most abstract knowledge consists of material drawn from semantic memory.
A 55-year-old heavy alcoholic was admitted to the medical ward after sustaining a major fall. He has severe Anterograde amnesia and extensive retrograde memory loss. However his working memory and procedural memory are unimpaired. What is his most likely diagnosis?
Select one:
1. Psychogenic amnesia
2. Transient organic amnesia
3. Korsakoff’s syndrome
4. Wernicke’s encephalopathy
5. Early stages of Alcoholic dementia
Korsakoff’s syndrome
Korsakoff’s syndrome: It is a form of an amnesic syndrome often occurring in patients with a history of
severe alcohol abuse leading to thiamine deficiency. The patient may have severe Anterograde amnesia
and extensive retrograde memory loss. This retrograde memory loss includes autobiographical memory loss with relative sparing of the most distant memories. Working memory and procedural memory are unimpaired. The pathological features are mostly found in paraventricular and periaqueductal grey matter, thalamus and mamillary bodies.
Of all sensory systems, the system least developed at birth is
Select one:
1. Vision
2. Smell
3. Taste
4. Touch
5. Balance
Vision
Of all the senses, sight is the least developed at birth; visual acuity in newborns is about 20/300
A 59-year-old man played Lotto consistently with the desire to win big one day. He has won small amounts
of money on certain occasions. What is the reinforcement schedule demonstrated by his behaviour?
Select one:
1. Fixed ratio
2. Variable interval
3. None of the above
4. Fixed interval
5. Variable ratio
Variable ratio
In variable ratio schedule, every nth response is rewarded on average, but the gap between two rewarded responses may be very small or fairly large; this schedule is found in fishing and gambling. This schedule is very resistant to extinction.
A candidate who is attempting his final exam before graduation thinks that he is going to fail the whole
exam as he has got one ‘obvious question’ wrong. He is exhibiting
Select one:
1. Overgeneralisation
2. Rationalisation
3. Projection
4. Denial
5. Splitting
Overgeneralisation
Generalising a small element to the whole is called overgeneralization- e.g. A depressed schoolteacher
thinks “one student in the class is sleeping so the entire class is bored of my lecture.”
Which of the following is an inaccurate statement concerning sensory memory?
Select one:
1. Sensory memory is modality specific
2.Each sense has its own sensory memory e.g. iconic (visual), echoic (auditory) etc.
3. Information is processed in sensory memory.
4. It has a large capacity but gets disrupted by inflow of new information in same modality
5. Information that is attended to is transferred to short-term memory store and information
that is not selected for processing is rapidly lost.
Information is processed in sensory memory.
Sensory memory: This is modality specific, has a large capacity but gets disrupted by the inflow of new
information in the same modality. Each sense has its own sensory memory e.g. iconic (visual), echoic
(auditory), etc. Iconic mode lasts for 0.5 seconds while echoic mode lasts for 2 seconds. No processing is
involved in sensory memory. Information that is attended to is transferred to short-term memory store, and information that is not selected for processing is rapidly lost.
Which one among the following is not correctly paired?
Select one:
1. Pavlov-Classical conditioning
2. Thorndike-Law of effect
3. Tolman-Latent learning
4. Skinner-Modelling
5. Kohler-insight learning
Skinner - Modelling
Modelling is a type of observational learning, explained by the social learning theory, and Bandura is the key name associated with it.
A medical student becomes more comfortable in the anatomy laboratory after several weeks of exposure to
it. Which of the following explains this process?
Select one:
1. Positive reinforcement
2. Habituation
3. Negative reinforcement
4. Modeling
5. Classical conditioning
Habituation
The decline in responsiveness or reaction to the repeated presentation of a stimulus is known as
habituation.
In a scientific experiment, a neutral stimulus (a bell) is paired with a stimulus (food) that produces an
autonomic response (salivation). Which of the following learning mechanisms has been employed?
Select one:
1. Systematic desensitisation
2. Shaping
3. Chaining
4. Operant conditioning
5. Classical conditioning
Classical conditioning
Classical conditioning is a basic form of learning. It was first described by Ivan Pavlov working on the
conditioned reflex. He was able to take an autonomic reflex (e.g., salivation to food) that was thought to be
unconditioned and demonstrated that it could be conditioned to respond to a new stimulus (e.g., a bell) if the new stimulus was presented along with or prior to the unconditioned stimulus (food). After a number of such presentations, the new stimulus (bell) would elicit the autonomic unconditioned response.
Skinner’s operant conditioning is based on which of the following principles?
Select one:
1. An association is learnt without overt behavioural expression
2. A response gets paired with a consequence
3. A response gets paired with its probability
4. A response gets paired with an inernal stimulus
5. A stimulus gets paired with a response
A response gets paired with a consequence
Skinner believed that the best way to understand behaviour is to look at the causes of an action and its
consequences. He called this approach operant conditioning.
Which of the following statements is correct concerning people with Type B personalities?
Select one:
They may be high achievers and workaholics
They cope poorly when under stress
All of the above
They show impatience and are incapable of relaxation
They show high competitiveness, hostility and aggression
They cope poorly when under stress
Type A persons show impatience, excessive time consciousness, insecurity, high competitiveness, hostility and aggression and are incapable of relaxation. They may be high achievers and workaholics.
Type B persons are relaxed, and easy-going, creative, often self-analyze and evade stress but cope poorly whenunder stress.
Wechsler Adult intelligence scales (WAIS-R) are for people
Select one:
Aged 15 and over
7 to 16 year olds
Aged 18 and over
3 to 7 year olds
Aged 16 and over
Aged 16 and over
Wechsler Adult intelligence scales-R is for those aged 16 and over. Wechsler intelligence scales for
children is for those aged 7 to 16 years. Wechsler preschool and primary intelligence is for 3 to 7.5 year old children.
Intelligent behaviors arise from a balance between analytical, creative and physical abilities. This notion
refers to which of the following?
Select one:
1. Sternberg’s theory
2. Spearman’s theory
3. Cyril Burt’s two factor model
4. Cattell & Horn intelligence model
5. Stanford-Binet theory
Sternberg’s theory
Sternberg’s Triarchic Theory of (Successful) Intelligence contends that intelligent behaviour arises from a
balance between analytical, creative and practical abilities, and that these abilities function collectively to
allow individuals to achieve success within particular sociocultural contexts (Sternberg, 1999).
A good test for recent memory is to ask patients which of the following?
Select one:
1. To subtract 7 from 100
2. Their date of birth
3. Spell WORLD backwards
4. What they had to eat for their last meal
5. Who is the prime minister of UK
What they had for their last meal
Recent memory is the ability to remember what has been experienced within the past few minutes (Recall
of items after five minutes), hours (Recall of last meal), days (Recall of recent topics in news). Remote
memory is the ability to remember events in the distant past (weeks to years). This can be tested by
inquiring about important dates in their lives such as date of birth, date of marriage and how many siblings
they have.
Strongest learning occurs when the delay is;
Select one:
1. More than 0.5 seconds
2. More than 5 seconds
3. Less than 5 seconds
4. Less than 0.5 seconds
5. More than 0.05 seconds
Less than 0.5 seconds
Longer the delay, the weaker the learning
A rat receives positive reinforcement (a food pellet) for pressing a bar that turns on a red light, but not an
adjacent bar that turns on a green light. The process that best explains this is
Select one:
1. Chaining
2. Operant conditioning
3. Containing
4. Systematic desensitization
5. Shaping
Operant conditioning
Operant conditioning, sometimes called instrumental conditioning, was formulated by Thorndike and later
developed by Skinner. In operant conditioning, a new behavioral response is learned, as compared with
classical conditioning in which a new stimulus is conditioned (learned) to elicit the same response or
behavior. In operant conditioning, reinforcement becomes the key stimulus that increases the likelihood that the desired behavior will be repeated or strengthened.
Which of the following is true regarding processes that govern formation of various types of memory?
Select one:
1. Attention allows decoding long term memory store
2. Lack of attention leads to forgetting
3. Attention allows short-term memory to enter long-term memory store
4. Attention allows sensory memory to enter short term memory store
5. Lack of attention leads to delay in recall
Attention allows sensory memory to enter short term memory store
Attention is a key process that enables sensory memory traces to enter into short term memory.
Which of the following can test abstract reasoning?
Select one:
1. Digit symbol substitution test
2. Clock drawing test
3. Trail making test
4. n-back test
5. Goldstein’s card sorting test
Goldstein’s card sorting test
The Goldstein-Scheerer Color Form Sorting Test was initially designed to test abstract reasoning (concept
formation rather than the simple identification of abstract rules). Wisconsin card sorting test is a descendant of Goldstein task and it tests concept identification rather than formation.
Which of the following is a projective test of personality?
Select one:
1. Cattell’s 16 PF test
2. Eysenck’s personality inventory
3. Minnesota Multiple Personality Inventory
4. International personality disorder examination
5. Thematic Apperception test
Thematic Apperception test
Murray was the proponent of projective personality tests though the first test produced was Rorschach’s ink blots. Thematic Apperception Test (Murray), Draw-a-person test, sentence completion tests are other
examples.
