2015 Exam October-November Flashcards

1
Q

Consider the following statements.
a) Thabo: “You know, as far as I’m concerned this talk about internal mental processes is
unscientific. Everybody knows that we can only conduct psychological research by
concentrating on actual, explicitly observable and quantifiable behaviours.”
b) Jeanette: “I don’t agree with you. I think that it is scientifically valid to construct theories
of internal mental processes if these theories are tested against empirical data.”
Given the assumptions they make about studying human cognition in a scientific manner,
contemporary cognitive psychologists are likely to agree with ___.
1) a, but not b
2) b, but not a
3) a and b
4) neither of the two statements

A

2) b, but not a

Reasoning: In cognitive psychology, empirical data and theories are both important. Theories are
empty without empirical data, and data in cognitive psychology can only be understood in the
context of an explanatory theory. Therefore option 4 is incorrect.

Q

Which of the following examples is most analogous to the goal of the structuralist movement in
psychology?
1) Scientists study an entire assembled jigsaw puzzle in order to understand each of the pieces
2) Scientists look at how the pieces of the jigsaw puzzle fit together in order to understand the
assembling process.
3) Scientists look at each piece of jigsaw puzzle in order to understand the whole puzzle as assembled.
4) Scientists study the different ways a jigsaw puzzle can be assembled to form different
images.

A

3) Scientists look at each piece of jigsaw puzzle in order to understand the whole puzzle as assembled.

Reasoning: Structuralism seeks to understand the structure (configuration of elements) of the
mind and its perceptions by analyzing those perceptions into their constituent components.

Q
Pavlov’s landmark experiment in which dogs salivate at the sight of the person who feeds them
provides an example of \_\_\_.
1) classically conditioned learning
2) instrumental learning
3) social learning
4) operant conditioning
A

1) classically conditioned learning

Reasoning: Pavlov said the dogs were demonstrating classical conditioning. He summed it up like
this: there’s a neutral stimulus (the bell), which by itself will not produce a response, like
salivation. There’s also a non-neutral or unconditioned stimulus (the food), which will produce an
unconditioned response (salivation).

Q

Lesiba says that in order to understand cognitive processes we need to look at the brain to see how
it functions. Ayami disagrees and argues that we must look at how people perform on various
cognitive tasks. This disagreement illustrates a debate in psychology concerning ___.
1) Validity of inference vs behavioural methods
2) Nature vs nurture
3) Biological vs behavioural methods
4) Rationalism vs empiricism

A

3) Biological vs behavioural methods

Reasoning: We can try to synthesize biological and behavioural methods so that we understand
cognitive phenomena at multiple levels of analysis.

Q

Adrian has been diagnosed as suffering from Parkinson’s disease and experiences difficulty in
planning and executing motor behaviours. The neurologist examining Adrian prescribed a drug, LDOPA,
to increase the level of the neurotransmitter ___, and this has helped to reduce Adrian’s
symptoms of Parkinson’s disease. However, since taking the drug Adrian spends most of his free
time playing poker and gambling on the internet.
1) serotonin
2) acetylcholine
3) GABA
4) dopamine

A

4) dopamine

Reasoning: Parkinson’s disease develops in the substantia nigra part of the brain when the cells
begin to die. These cells produce dopamine and the loss of dopamine in the brain leads to issues
with movement. However, there are behavioural side effects, such as impulsive and compulsive
behaviors during dopamine replacement treatment in Parkinson’s Disease and other disorders.

which is important for regulating the overall level of arousal and consciousness.
1) corpus callosum
2) amygdala
3) reticular activating system
4) medulla oblangata

A

3) reticular activating system

Reasoning: The reticular activating system is important in controlling consciousness (sleep
arousal), attention, cardiorespiratory function and movement.

Q

Which neurotransmitter is important for regulating impulsivity and is also associated with some
types of anorexia, and with aggressive behavior?
1) Acetylcholine
2) Dopamine
3) GABA
4) Serotonin

A

4) Serotonin

Reasoning: Serotonin plays an important role in eating behavior and body weight regulation. High
serotonin levels play a role in some types of anorexia, specifically anorexia resulting from illness or
treatment of illness. Serotonin is also involved in aggression and regulation of impulsivity. Drugs
that block serotonin tend to result in an increase in aggressive behavior.

Q

Split brain patients have had their a) surgically removed, to prevent b)

1) a) optic chiasma; b) prosopagnosia
2) a) thalamic nuclei; b) Parkinson’s tremors
3) a) corpus callosum; b) epileptic seizures
4) a) hypothalamus; b) endocrinic abnormalities and hypothermia

A

3) a) corpus callosum; b) epileptic seizures

Reasoning: The procedure involves severing the corpus callosum, the main bond between the
brain’s left and right hemispheres. After a split-brain surgery the two hemispheres do not
exchange information as efficiently as before. The split-brain phenomenon is usually the result of
a surgery to treat refractory epilepsy.

Q

Damage to the hippocampus due to thiamine (Vitamin B-1) deficiency can result in a loss of memory
function in which an individual is still able to recall information learned in the past, but is unable to
form new memories. This is known as ___.
1) Benzine syndrome
2) apraxia
3) aphasia
4) Korsakoff’s syndrome

A

4) Korsakoff’s syndrome

Reasoning: Korsakoff syndrome is a chronic memory disorder caused by severe deficiency of
thiamine (vitamin B-1). Korsakoff syndrome is most commonly caused by alcohol misuse, but
certain other conditions also can cause the syndrome.

Q

___ refers to instances in perception where we (unconsciously) divide visual information into two
parts in which some of the information appears closer and better defined while the rest of the
information appears further away and de-emphasized.
1) Object specification
2) Binocular depth cues
3) Decompositional analysis
4) Figure-ground

A

4) Figure-ground

Reasoning: Figure-ground refers to what stands out from versus what recedes into the
background.

Q

Melanie has a peculiar perceptual deficit. She cannot recognize familiar faces, and she claims that
even close relatives are complete strangers and that she has never seen them before. Melanie
probably suffers from ___.
1) protanopia
2) prosopagnosia
3) simultagnosia
4) akinetopsia

A

2) prosopagnosia

Reasoning: Prosopagnosia is a neurological disorder characterized by the inability to recognize
faces. Prosopagnosia is also known as face blindness or facial agnosia. The term prosopagnosia
comes from the Greek words for “face” and “lack of knowledge.”

Q

Jerry is trying to find his seat in a movie theatre in which the light has been dimmed. These long thin
photoreceptors are very sensitive to light, and are the cells that primarily contribute to Jerry’s ability
to distinguish objects in this dim light. They are called ___.
1) cones
2) cells in the foveal region of the retina
3) rods
4) ganglion cells

A

3) rods

Reasoning: The rods are long, thin photoreceptors that are responsible for night vision and are
sensitive to light and dark stimuli.
• Cones (option 1) are short and thick photoreceptors and allow for the perception of
colour.

17
Q

Which of the following statements involve mainly top-down processing and which involve mainly
bottom-up processing?
a) Interpreting the meaning of mispronounced or missing words
b) Finding every ‘’e’’ in a given passage
c) Finding every noun in a given passage
d) Guessing what a word is when the handwriting is bad
1) Top-down = (a), (b); Bottom-up = (c), (d)
2) Top-down = (a), (c), (d); Bottom-up = (b)
3) Top-down = (b), (c), (d); Bottom-up = (a)
4) Top-down = (a), (d); Bottom-up = (b), (c)

A

4) Top-down = (a), (d); Bottom-up = (b), (c)

Reasoning: In top-down processing the emphasis is placed on how a person’s concepts
and higher-level memory processes influence the recognition and interpretation
of the perceptual information. Knowledge of context improves the accuracy of your perception
because it allows you to draw from previously acquired background knowledge, and therefore
fosters top-down processing.
Bottom-up theories depend primarily on stimulus-based processing rather than knowledge. In
bottom-up processing the importance of the properties of the stimulus (e.g. shape, colour and
constituent features) is emphasised. These properties are used to interpret the information
registered by the sensory receptors.

18
Q

___ occurs when our perception of an object remains the same even if we move further away. If we
move away from an object the size of the proximal stimulus changes because the same object at two
different distances will project two different-sized images on the retina.
1) Binocular Depth perception
2) Monocular Depth perception
3) Relative-size illusion
4) Perceptual constancy

A

4) Perceptual constancy

Reasoning: Perceptual constancy refers to the tendency to perceive an object you are familiar
with as having a constant shape, size, and brightness despite the stimuli changes that occur.

19
Q

This hypothesis suggests that there are two distinct visual pathways in the brain, one pathway is
important for identifying the object and the other for identifying the function of the object.
1) Object Identity/Object Location
2) Object Identity/ Object Position
3) What/How
4) What/Where

A

3) What/How

Reasoning: There are two visual pathways, one is the what/where, and the other is the
how/what. Therefore options 1 and 2 are incorrect.
To determine which option (3 or 4) is correct, we read what the question relates to. Function
refers to ‘how’ and identification refers to ‘what’. Therefore, option 3 is correct

20
Q

If you were to study top-down processing as it applies to smell, which one of the following topics
would be most relevant?
1) Whether people recognize a lemon fragrance more readily when they see a photo of a lemon than when they see a photo of a rose.
2) Whether the chemical structure of the lemon fragrance molecules is substantially different
from the chemical structure of rose-fragrance molecules.
3) Whether the receptors in the nasal passage respond differently to lemon and rose
fragrances
4) Whether the portion of the brain that receives information about smell stores different
fragrances in different locations.

A

1) Whether people recognize a lemon fragrance more readily when they see a photo of a lemon than when they see a photo of a rose.

Reasoning: In top-down processing the emphasis is placed on how a person’s concepts
and higher-level memory processes influence the recognition and interpretation
of the perceptual information. Knowledge of context improves the accuracy of your perception
because it allows you to draw from previously acquired background knowledge, and therefore
fosters top-down processing.
Bottom-up theories depend primarily on stimulus-based processing rather than knowledge. In
bottom-up processing the importance of the properties of the stimulus (e.g. shape, colour and
constituent features) is emphasised. These properties are used to interpret the information
registered by the sensory receptors.

21
Q

The two eyes send increasingly disparate images to the brain as objects approach the eyes. The brain
interprets the degree of disparity as an indication of distance from the person. The major depth cue
represented in this description is ___.
1) binocular disparity
2) interposition
3) binocular convergence
4) motion parallax

A

1) binocular disparity

Reasoning: Binocular disparity refers to the difference in image location of an object seen by the
left and right eyes, resulting from the eyes’ horizontal separation (parallax). The brain uses
binocular disparity to extract depth information from the two-dimensional retinal images in
stereopsis.

22
Q

According to the viewpoint of ___ perception, the array of information in the sensory receptors
together with the sensory context is all that is needed for human perception. It is not necessary to
postulate prior knowledge or complex computational processes and heuristics are essential for
perception to occur.
1) synthetic
2) unconscious
3) direct
4) constructive

A

3) direct

Reasoning: In this theory of direct perception Gibson maintains that there is enough contextual
information available in the world to interpret visual stimuli and that it is unnecessary to postulate
the need for higher-order cognitive operations in perception.

23
Q

Research on humans as well as non-human animals have shown that visual shape is processed in the
ventral stream as well as visual areas such as the ventral temporal cortex and the lateral occipital
cortex. Processing has been found to occur in which of the following sequences?
1) The process starts with activation of the primary visual cortex and parietal cortex, then
depth and shape information are acquired in the V5 region of the visual cortex, and after
this moving 3-D shapes are processed in the human motion complex (hMT)
2) Initially depth and shape information are acquired in the V5 region of the visual cortex, then
there is activation in the parietal cortex, and after this moving 3-D shapes are processed in
the human motion complex (hMT)
3) The process starts with activation of the parietal cortex, then moving 3-D shapes are
processed in the human motion complex (hMT), then depth and shape information are
acquired in the V5 region of the visual cortex.
4) Initial processing occurs in the primary visual cortex, then moving 3-D shapes are processed
in the human motion complex (hMT), after this depth and shape information are acquired in the V5 region of the visual cortex, and then in the final stage there is activation of the primary visual area and parietal cortex.

A
