It has been proposed that the formation of episodic associations between stimuli may involve different processes when memoranda are from the same or different perceptual domains, and when stimuli are experienced concurrently or sequentially. Such differences are postulated to determine the degree of unitization of memoranda, and are asserted to…

Emotionally arousing information is remembered better than neutral information. This enhancement effect has been shown for memory for items. In contrast, studies of association-memory have found both impairments and enhancements of association-memory by arousal. We aimed to resolve these conflicting results by using a cued-recall paradigm combined…

Five experiments were conducted to examine how unsuccessful retrieval influences learning and subsequent memory. We used a cued-recall paradigm that produces many unsuccessful retrieval attempts (followed by feedback) and allows comparisons to be made between later memory for these trials and trials that only required reading or studying the…

In three experiments, we evaluated remembering and intentional forgetting of attitude statements that were either congruent or incongruent with participants' own political attitudes. In Experiment 1, significant directed forgetting was obtained for incongruent statements, but not for congruent statements. In addition, in the remember group, recall…

False memories arising from associatively related lists are a robust phenomenon that resists many efforts to prevent it. However, a few variables have been shown to reduce this form of false memory. Explanations for how the reduction is accomplished have focused on either output monitoring processes or constraints on access, but neither idea alone…

Dual-process models differentiate between two bases of memory, recollection and familiarity. It is routinely claimed that deeper, semantic encoding enhances recollection relative to shallow, non-semantic encoding, and that recollection is largely a product of semantic, elaborative rehearsal. The present experiments show that this is not always the…

We explore competing explanations for the reduction in false alarm rate observed when studied items are strengthened. Some models, such as Retrieving Effectively from Memory (REM; Shiffrin & Steyvers, 1997), attribute the false alarm rate reduction to differentiation, a process in which strengthening memory traces at study directly reduces the…

Retrieving information from memory produces more learning than does being presented with the same information, and the benefits of such retrieval appear to grow as the delay before a final recall test grows longer. Recall tests, however, measure the number of items that are above a recall threshold, not memory strength per se. According to the…

Normative word frequency and context variability affect memory in a range of episodic memory tasks and place constraints on theoretical development. In four experiments, we independently manipulated the word frequency and context variability of the targets (to-be-generated items) and cues in a cued recall paradigm. We found that high frequency…

We used quantitative modeling of remember-know responses (Tulving, 1985) to investigate the processes underlying recognition memory for faces in the choice-similarity paradigm (Tulving, 1981). Similarity between recognition test choices produces opposite effects on confidence and accuracy in this paradigm. We extended existing models of this…

Three experiments examine whether a naturalistic reading task can induce long-lasting changes of syntactic patterns in memory. Judgment of grammatical acceptability is used as an indirect test of memory for sentences that are identical or only syntactically similar to those read earlier. In previous research (Luka & Barsalou, 2005) both sorts of…

Temporal distinctiveness models of memory retrieval claim that memories are organised partly in terms of their positions along a temporal dimension, and suggest that memory retrieval involves temporal discrimination. According to such models the retrievability of memories should be related to the discriminability of their temporal distances at the…

Temporally grouping lists has systematic effects on immediate serial recall accuracy, order errors, and recall latencies, and is generally taken to reflect the use of multiple dimensions of ordering in short-term memory. It has been argued that these representations are fully relative, in that all sequence positions are anchored to both the start…

Emotionality is a key component of subjective experience that influences memory. We tested how the emotionality of words affects memory monitoring, specifically, judgments of learning, in both cued recall and free recall paradigms. In both tasks, people predicted that positive and negative emotional words would be recalled better than neutral…

The relation between intrusions in several different recall tasks was examined in the current study. Intrusions from these tasks were moderately correlated and formed a unitary intrusion factor. This factor was related to other cognitive ability measures including working memory capacity, judgments of recency, and general source-monitoring…
