What did Cattell’s 1895 book “Measurements of the Accuracy off Recollection” investigate?
asked 56 university students in psychology to recall things they had witnessed in their every-day lives. He found that students’ answers were often inaccurate, and that the relationship between the participants’ accuracy and their confidence was far from perfect.
“Cattell’s 1895 book, “Measurements of the Accuracy off Recollection,” investigated human memory and the accuracy of recollecting past experiences. In his book, Cattell sought to measure the variability of recollection accuracy across different individuals and to identify factors that might influence these individual differences. To do this, he conducted a series of experiments in which he asked participants to recall and recognize items from a previously presented list. He then analyzed their performance data to determine which factors, such as age, gender, or education, may have contributed to the accuracy of their recollection. The book is considered a landmark in the field of psychology and memory research, as it helped establish the method of using objective measures and statistical analyses in the study of cognitive psychology.”
