Note : Go through the following passage carefully and select the correct answer of the five (5) questions (5); given below (Question no. 36 to 40): PASSAGE Memory is a cognitive ability to encode, store and retrieve information from the environment. According to the information theory, the amount of information per item is simply the logarithm (to the base 2) of the number of choices. George Miller in1956 suggested that human ability to process information is a magical number 7 ± 2. It is therefore possible to calculate the number of 'bits' of information that a subject can hold when he correctly reports 5 or 6 or 7 or 8 or 9 digits. For example each digit is drawn from 10 equally likely alternatives and therefore each decimal digit contains 3.32 bits of information (23.32 = 10). Similarly each binary digit (0,1) contains 1 bit of information (21= 2). Each English alphabet contains 4.7 bits of information (24.7 = 26). Therefore from 'information theory1 point of view, if the span of memory of a subject for decimal digit is 7, then he store 32 × 7 = 27 bits of information approximately. 'Bit' which is contraction of 'binary' digit is the amount of information needed to distinguish between two equally likely alternatives. Thus N bits is the number of 'bits' required to distinguish among 2N equally likely alternatives. This measurement of information contained in any given stimulus was initially propounded by Shanon and Weaver.36. Memory span for digits is magical number 7 ± 2 was suggested by :
