Cognitive Biology/Psychology Questions
1) Psychologists distinguish between single code and dual code systems. It is generally believed that human cognition is
(a) A single-code system (b) A dual-code system (c) Psychologists have not been able to determine which type of system we have in our heads.
2) Visual mental representations presumably has some specific cognitive function, or else we wouldn’t have them. Which of these alternatives best describes the view cognitive psychologists take about this:
(a) Visual representations do not help with either memory or thinking, so they must have some other purpose.
(b) There is strong evidence that visual representations support memory, but no evidence that they support thinking.
(c) There is strong evidence that visual representations support thinking, but no evidence that they support memory.
(d) There is good evidence that visual representations support both memory or thinking
3) There are multiple phenomena that demonstrate that perception is selective. One of these phenomena is:
(a) Rainbows (b) Infrared radiation (c) Movies (d) Reversible figures
4) A person lost vision in one eye, while the other eye was undamaged. He see well enough but showed a tendency to misjudge distances. The cause of this was probably:
(a) The increased selectivity of perception due to the damage in one eye. (b) The loss of stereopsis. (c) The operation of the common fate principle (d) The phi phenomenon
5) The section on visual imagery raised the question whether visual images really are visual in some fundamental sense. After reviewing the evidence we can say:
a) There is no evidence that visual images actually occupy the same brain centers and engage the same processes as vision.
b) The behavioral evidence consistently supports the idea that images are visual, but some clinical case studies contradicted this.
c) The behavioral evidence contradicted the idea that images are visual, but there was totally consistent support from the neuroscience and clinical evidence.
d) All the types of evidence reviewed consistently showed support for the idea that visual images are truly visual.
6) The Mental Rotation Method employs which dependent variable:
(A) The number of degrees of rotation. (B) The reaction time. (C) The proportion correct. (D) The number of rotations per trial.
Explanation / Answer
1. Answer: b
Dual coding theory (DCT) explains human behavior and experience in terms of two distinct classes of mental representation. These are the verbal representations and mental images. These are two functionally independent and interacting systems.
2. Answer: d
It is very widely believed that much imagery or visual representation functions as mental representations or mental models, playing an important role in memory and thinking
3. Answer: b
Not all physical characteristics of objects are accessible to perception: for example ultraviolet and infrared radiations are invisible, sound waves of extremely high or low frequencies are inaudible. Hence infrared radiations demonstrate that perception is selective.
4. Answer: b
A person who lost sight in one eye would only be able to see monocular cues. They would not be able to view objects in 3D or stereopsis. Because of the loss of stereopsis they tend to misjudge distances.
6. Answer: b
The primary dependent variable is reaction time, with percent accuracy as a secondary dependent variable.
