2. Which of the following statements are correct and/or incorrect about the subsystems in working memory? I. The visuospatial sketchpad can account for the word length effect II. The Corsi block task measures spatial memory a. Both statement I and II are correct b. Statement I is correct, but statement II is incorrect c. Statement I is incorrect, but statement II is correct d. Both statement I and II are incorrect
The correct answer is C The word length effect refers to reduced verbal memory span as words become longer. This effect is evidence for the role of articulation, a subpart of the phonological loop rather than the visuospatial sketchpad. Longer words require subvocal rehearsal to be recalled. Thus, patients with phonological STM deficits do not show phonological similarity effect nor word-length effect when presented with words visually. Moreover, a distinction between visual and spatial memory can be provided by using the pattern span task and Corsi block task to measure each, respectively. The Corsi block tapping task involves the experimenter tapping blocks and asking the subject to imitate the same sequence. The sequence increases gradually until the subject makes an error. Performance in this task is disrupted by spatial interference.
Which of the following statements is NOT correct about enzymes? a. Enzyme MAO can be targeted by psychotropic drugs b. Binding to irreversible inhibitors makes the enzyme nonfunctional c. Enzyme activity converts a substrate into a product d. Substrates and products for each enzyme are not selective
The correct answer is D A Enzymes known to be targeted by psychotropic drugs currently used in clinical practice: monoamine oxidase (MAO) and acetylcholinesterase. B Irreversible enzyme inhibitor is sometimes called “suicide inhibitor” because binds to the enzyme and permanently inhibits it, making it nonfunctional forever. C Enzyme activity is the conversion of on molecule into another. The substrate binds to the enzyme’s active site and it is turned into a product by enzymatic transformation, then it is released from the enzyme. D The substrates and products for each enzyme are unique and selective.
