People tend to judge more recent events, relative to earlier ones, as the cause of some particular outcome. For instance, people are more inclined to judge that the last basket, rather than the first, caused the team to win the basketball game. This recency effect, however, reverses in cases of overdetermination: people judge that earlier events, rather than more recent ones, caused the outcome when the event is individually sufficient but not individually necessary for the outcome. In five experiments (...) (N = 5507), we find evidence for the recency effect and the primacy effect for causal judgment. Traditionally, these effects have been a problem for counterfactual views of causal judgment. However, we argue that an extension of a recent counterfactual model of causal judgment explains both the recency and the primacy effect. In line with the predictions of our extended counterfactual model, we also find that, regardless of causal structure, people tend to imagine the counterfactual alternative to the more recent event rather than to the earlier one. Moreover, manipulating this tendency affects causal judgments in the ways predicted by this extended model: asking participants to imagine the counterfactual alternative to the earlier event weakens the interaction between recency and causal structure, and asking participants to imagine the counterfactual alternative to the more recent event strengthens the interaction between recency and causal structure. We discuss these results in relation to work on counterfactual thinking, causal modeling, and late-preemption. (shrink)

An item that stands out (is isolated) from its context is better remembered than an item consistent with the context. This isolation effect cannot be accounted for by increased attention, because it occurs when the isolated item is presented as the first item, or by impoverished memory of nonisolated items, because the isolated item is better remembered than a control list consisting of equally different items. The isolation effect is seldom experimentally or theoretically related to the primacy or the (...) class='Hi'>recency effects—that is, the improved performance on the first few and last items, respectively, on the serial position curve. The primacy effect cannot easily be accounted for by rehearsal in short‐term memory because it occurs when rehearsal is eliminated. This article suggests that the primacy, the recency, and the isolation effects can be accounted for by experience‐dependent synaptic plasticity in neural cells. Neurological empirical data suggest that the threshold that determines whether cells will show long‐term potentiation (LTP) or long‐term depression (LTD) varies as a function of recent postsynaptic activity and that synaptic plasticity is bounded. By implementing an adaptive LTP‐LTD threshold in an artificial neural network, the various aspects of the isolation, the primacy, and the recency effects are accounted for, whereas none of these phenomena are accounted for if the threshold is constant. This theory suggests a possible link between the cognitive and the neurological levels. (shrink)

Argues that although the phenomenon of negative recency in secondary memory is usually attributed to the reduced amount of rehearsal associated with recency items, this phenomenon can be explained by the adoption of a different type of processing for recency items. An experiment with 122 undergraduates is reported in which the recall of recency items was reduced in an immediate test, but increased in a subsequent test, under conditions in which the recency items could not (...) be identified as such during their presentation. Results support the conclusion that the mode of processing items for an immediate free-recall test is normally modified for recency items. ((c) 1997 APA/PsycINFO, all rights reserved). (shrink)

ABSTRACTDynamic changes in emotional expressions are a valuable source of information in social interactions. As the expressive behaviour of a person changes, the inferences drawn from the behaviour may also change. Here, we test the possibility that dynamic changes in emotional expressions affect person perception in terms of stable trait attributions. Across three experiments, we examined perceivers’ inferences about others’ personality traits from changing emotional expressions. Expressions changed from one emotion to another emotion, allowing us to disentangle potential primacy, (...) class='Hi'>recency, and averaging effects. Drawing on three influential models of person perception, we examined perceptions of dominance and affiliation, competence and warmth, and dominance and trustworthiness. A strong recency effect was consistently found across all trait judgments, that is, the end emotion of dynamic expressions had a strong impact on t... (shrink)

Drawing on the influence of primacy and recency effects in processing information about corporate social responsibility, the authors examine how internal and external factors impact the consumer-firm relationship in the presence of contradictory CSR information. Evaluating these factors provides a more comprehensive understanding of how consumers react to unethical and socially irresponsible actions. Contrary to recent research that suggests a reactive CSR communication strategy to be best due to recency effects, the present findings show that past customer experiences (...) with the firm facilitate a ‘primacy effect’. Thus, when corporate social irresponsibility occurs, a customer’s prior experiences mitigate negative consequences. Conversely, a firm’s positive CSR reputation may provide goodwill, although it does not guarantee that consumers will process CSR information differently. Therefore, firms cannot build a strong CSR reputation and expect to be immune from the consequences of CSI. Given these new findings of how consumers process contradictory CSR information, firms should implement a strategic and deliberate communication plan that delivers different messages to different stakeholders. Specifically, these findings suggest that firms benefit most from a proactive communication strategy with their current customers and a reactive communication strategy with the general public.
