1.vascular disorder 2.aphasic stroke 3.dratonin 4.neoplasms Option 1 is correct. A vascular disorder occurs when there is a disruption of blood flow to the brain caused by a stroke, and this usually has an effect on cognitive functioning (COG, pp. 126-127). Option 4 is incorrect because neoplasm is a brain tumour, and although a tumour can have a significant effect on cognitive processing, it does not entail a blood flow problem. Option 2 is incorrect because an aphasic stroke is a stroke resulting in an impairment of language functions, but this type of stroke could also have resulted from a hemorrhage (rupture of a blood vessel), and not necessarily from a blood flow problem. QUESTION 29 A person who has suffered some sort of brain injury affecting only his or her hippocampus is most likely to show difficulty with: 1.the consolidation of encoded information in the long-term store. 2.encoding of procedural information. 3.retrieval of semantic information. 4.retrieval of episodic information Option 1 is correct. As the discussion in CPOG (pp. 223-224) shows, the hippocampus appears to play a pivotal role in the transference of information from short-term to long-term memory. The main functions of the hippocampus are also discussed on page 97 in COG. Options 2, 3, and 4 are incorrect because the difficulty lies not just in retrieving or encoding information for ‘short durations’, but in remembering it over a period of time.
