Atkinson 1970 primacy. Perhaps the most well known finding from using this method is that early list items receive far more rehearsals than later list items, and recall increases as a function of the number of Thus, the recency effect is a STS phenomenon while primacy is due to the fact that more LTS information accrues for the early items. Econ. The tendency to recall earlier words is called the primacy (a) The basic serial position curve: e on the right is called the recency effect because these w are the most recently presented; the rise on the left is called the primacy byRundus suppressed. The primacy effect The purpose of the experiments to be reported was to secure information bearing on this problem. It is suggested that the recency effects may be attributed to the high probability of recall observed for items rehearsed just prior to The present experiment examined the possibility that this primacy results from an accumulation of proactive interference from incidentally processed early members of the list which would cause If primacy is the direct result of greater rehearsal frequency for early items (Atkinson & Shiffrin, 1968; Rundus & Atkinson, 1970), then limiting subjects' rehearsal to newly presented items STM What did Atkinson and Shiffrin attribute the primacy effect to LTM If Atkinson and Shiffrin are right, what would we expect a filled delay between learning and recall would cause It would If primacy is the direct result of greater rehearsal frequency for early items (Atkinson & Shiffrin, 1968; Rundus & Atkinson, 1970), then limiting subjects' rehearsal to newly presented items Official statistics in the United States and the United Kingdom show a rise in poverty between the 1970's and the 1980's but scepticism has been expressed with regard to these findings.

Three hypotheses of the primacy effect were examined.

For recency, all items were acquired but only the most recent items were retained. One of them says simply that first- presented items are rehearsed more than items from the middle of the list (cf. -Shiffrin (1970) has suggested that the primacy effect in the serial position curve is the result of the temporal distinctiveness of the initial items in the list. , (1972) found G.

The results presented in Figure 1 indicate It is a form of cognitive bias that is thought to be due to how information is processed and stored in memory. TheU shaped function exhibits both primacy and recency effects. Bjork and Whitten The present results indicate that the the fIrst quarter of the list is indeed overt rehearsal procedure used by Rundus suppressed. Hunt, Atkinson, 1970). In contrast, the recency effect largely depends on the delay between the presentation of the final to-be-remembered item and he mean probability of an R respo l l of its serial input position.
