Uncoupling learning from initial recall
Nettelbeck & Rabbitt (1992) found that measures of speed of performance with low knowledge requirements (four‐choice reaction time, inspection time and coding‐substitution) accounted substantially for age‐related changes among 104 persons aged from 54 to 85 years in a number of more complex cognitive measures reflecting general fluid ability. However, the numbers of words recalled from a list after either a single brief viewing of each word, or f…
Speed and Accuracy of Memory Decisions in Older Adults
An experiment examined the speed and accuracy with which older individuals made decisions about the contents of their memory. 63 volunteers aged between 50 and 80 years made speeded decisions about whether they knew the meaning of rare words presented to them on a computer screen followed by a forced-choice recognition test to assess the veracity of the memory decisions. Subjects were required to select 3 targets from a list of 10 that together c…
Investigating models of human performance
In Decision and Stress , Broadbent (1971) highlighted the deficiencies of steady‐state information‐processing systems and recommended a methodology for studying change and individual variability in human performance. Some implications of his approach are considered here by reviewing studies of the ways in which performance in choice reaction time, visual search and simple memory tasks is affected by individual differences in age and intelligence,…
Comparing the effects of alcohol and intelligence on text recall and recognition
Forty male subjects were divided into two groups on the basis of their scores on a computerized intelligence test administered in a preliminary session. They then participated in a text recall and recognition experiment in which they received alcohol (1.0 ml/kg body weight) in one session and no alcohol in another session (the order being counterbalanced). Subjects were required to read a short passage, immediately recall as much of it as possibl…
Response times to stimuli of increasing complexity as a function of ageing
Twelve elderly and 12 young subjects were tested on a series of experiments with increasing complexity of perceptual‐response mapping. As task complexity increased the differential slowing in performance between young and old increased and an age × task complexity interaction was observed. However, with practice this phenomenon disappeared leaving an apparent age lag constant. This slowing was due to increased central processing time rather than …
Ignoring Irrelevant Information
The task of scanning a visual display to identify certain symbols may involve ignoring the presence of others, and so may be compared with Donders's 1862 study of the ‘ c ‐reaction’, in which a response was required to only one of a set of five possible phonemes presented to a subject in random succession. For visual displays of letters of the alphabet the time required to ignore a symbol as irrelevant is shown to depend upon the vocabulary of it…
