File = E:\p355\old\win09\final.b.a-key.doc 1 John Miyamoto Email: jmiyamot@u.washington.edu http://faculty.washington.edu/jmiyamot/p355/p355-set.htm Psych 355: Introduction to Cognitive Psychology Winter 2009 Psychology 355: Final Examination, ANSWER KEY, Form B 1. A double dissociation has been observed in brain injuries that affect semantic and episodic memories. What does this mean? a) Patients have been found who have impairment to both semantic and episodic memory. b) Brain injuries always impair both forms of memory, or neither forms of memory. c) Î Patients have been found who have impairment to semantic memory but not to episodic memory, and other patients have been found who have impairment to episodic memory but not to semantic memory. d) fMRI reveals that brain injuries that affect semantic memory are in different parts of the brain from brain injuries that affect episodic memory. [Technically, this answer is not correct because a double dissociation can be found as in (c) without having evidence that the brain injuries are in different parts of the brain. Nevertheless (d) strongly suggests that (c) is true, so we are counting (d) as correct as well as (c).] 2. Information is transmitted from one neuron to a contiguous neuron by what process? a) Î Chemicals called neurotransmitters are released by one neuron and absorbed by contiguous neurons at specialized neural structures called synapses. b) Electricity is transmitted from one neuron to another at places where they touch each other. c) Electricity that is flowing through one neuron creates a magnetic field that induces an electrical current in adjacent neurons. d) Neurons release pheromones into the blood or lymph system. These pheromones are absorved by other neurons. 3. Suppose that neuron A provides input to neuron B at a synapse. Neuron A is excitatory with respect to neuron B if: a) neuron B fires whenever neuron A fires. b) neurons A and B tend to fire in synchrony. c) Î increased firing of neuron A produces increased firing of neuron B. d) increased firing of neuron A produces decreased firing of neuron B. 4. The behavioral approach to the study of mind refers to what? a) the use of behaviorist methods, like reinforcement conditioning, to shape behavior. b) Î inferring cognitive processes and mental representations from observed behavior under specified conditions. c) measuring both behavior and physiology and explaining cognition in terms of physiology. d) explaining behavior by means of computer simulations of the behavior. 5. Reaction time refers to the time between the of a stimulus and a subject's response to the stimulus. What is the missing word? a) perception
