I find that exactly two stages can be seen directly in sequential free recalldistributions. These distributions show that the first three recalls come fromthe emptying of working memory, recalls 6 and above come from a second stageand the 4th and 5th recalls are mixtures of the two. A discontinuity, a roundedstep function, is shown to exist in the fitted linear slope of the recalldistributions as the recall shifts from the emptying of working memory(positive slope) to the second stage (negative slope). The discontinuity leadsto a first estimate of the capacity of working memory at 4-4.5 items. Workingmemory accounts for the recency effect. The primacy effect comes from thesecond stage with a contribution also from working memory for short lists (thefirst item). The different slopes of the working memory and secondary stages,and that the two have different functional forms, accounts for the u-shapedserial position curve. The total recall is shown to be a linear combination ofthe content of working memory and items recalled in the second stage with3.0-3.9 items coming from working memory, a second estimate of the capacity ofworking memory. A third, separate upper limit on the capacity of working memoryis found (3.06 items), corresponding to the requirement that the content ofworking memory cannot exceed the total recall, item by item. This third limitpresumably corresponds to the least chunked item. This is the best limit on thecapacity of unchunked working memory.

First direct evidence of two stages in free recall and three corresponding estimates of working memory capacity
