Attention Span StatisticsĪccording to The Associated Press the following interesting statistics regarding attention spans exist.ġ. The description of Digit Span - Memory Game App. The following statistics regarding average attention spans are outlined below. From babies to children to adults, the attention span of a child will get longer with age. The results are further interpreted in terms of Kyllonen's theory that working memory capacity is 'g.' If this is accepted, it follows that males have an advantage in 'g' and that the higher average means obtained by men in IQ tests like the WAIS and the Progressive Matrices is attributable to their advantage in 'g.When considering the average attention span of individuals, age is a determining factor of this.

If this is accepted, the results indicate that there is virtually no sex difference in immediate memory capacity (measured by digit span) but a small male advantage among children and a substantial male advantage among adults in working memory capacity (measured by mental arithmetic). It is proposed that the reason for this is that mental arithmetic is a measure of working memory capacity while digit span is a measure of immediate memory capacity. These results show that the sex differences on mental arithmetic are not consistent with the sex differences on digit span. Items can be kept in short term memory by repeating them verbally (acoustic encoding), a process known as rehearsal. The duration of short term memory seems to be between 15 and 30 seconds, according to Atkinson and Shiffrin (1971). Meta-analyses are presented of sex differences in (1) the (mental) arithmetic subtest of the Wechsler intelligence tests for children and adolescents (the WISC and WPPSI tests), showing that boys obtained a mean advantage of 0.11d (2) the (mental) arithmetic subtest of the Wechsler intelligence tests for adults (the WAIS tests) showing a mean male advantage of 0.47d (3) the digit span subtest of the Wechsler intelligence tests for children and adolescents (the WISC and WPPSI tests), showing that girls obtained a mean advantage of 0.134d (4) the digit span subtest of the Wechsler intelligence tests for adults (the WAIS tests) showing a male advantage of 0.116d among adults. The average span for letters was 7.3 and for numbers it was 9.3.
