Serial recall is often assumed to involve response suppression: the removal or inhibition of items already recalled so that they are not recalled again. Evidence for response suppression includes repetition inhibition and the separation of erroneous repetitions. Some theorists have suggested that response suppression, by eliminating competing responses, also contributes to recency in forward serial recall. We present experiments in which performance on the final item was examined as a function of whether or not the preceding retrievals entailed suppression of potential response competitors. In line with the predictions of response suppression, recency was found to be reduced when the earlier recall errors consisted of intrusion errors (which leave list items unsuppressed) rather than transposition errors (which involve suppression).

Most climate experts agree that human carbon dioxide emissions cause anthropogenic global warming (AGW), reflected in increased global temperatures during every decade since 1970. Nonetheless, some public figures have claimed that AGW stopped in 1998. In a large experiment (N = 200), participants extrapolated global climate data, presented graphically either as share prices or as temperatures. Irrespective of their attitudes toward AGW, and irrespective of presentation format, people judged the trend to be increasing. These results suggest that presentation of climate data can counter claims that AGW has stopped.
