Memory retrieval affects subsequent memory in ways both positive (e.g., the testing effect) and negative (e.g., retrieval-induced forgetting, RIF). The changes to memory that retrieval produces can be thought of as the encoding consequences of retrieval, examined here with respect to attention. In three experiments, participants first studied…

Retrieval enhances subsequent memory more than restudy (i.e., the testing effect), demonstrating the encoding (or reencoding) effects of retrieval. It is important to delineate the nature of the encoding effects of retrieval especially in comparison to traditional encoding processes. The current study examined if the level of retrieval, analogous…

Ancient as well as modern writers have promoted the idea that bizarre images enhance memory. Research has documented bizarreness effects, with one standard technique finding that sentences describing unusual, implausible, or bizarre scenarios are better remembered than sentences describing plausible, every day, or common scenarios. Not…

The generation effect is moderated by experimental design, as are a number of other encoding variables, such that the generation effect recall is typically larger in mixed-list than pure-list designs. In typical experiments on design effects, each study list is followed by its own recall test. Rowland, Littrell-Baez, Sensenig, and DeLosh (2014)…

Memory retrieval often enhances later memory compared with restudying (i.e., the testing effect), indicating that retrieval does not simply reveal but also modifies memory representations. Dividing attention (DA) during encoding greatly disrupts later memory performance while DA during retrieval typically has modest effects--but what of the…

Memory retrieval often enhances still later memory as evidenced by the testing effect. Divided attention (DA) is known to produce different effects on encoding and retrieval, substantially disrupting the former and often producing little effect on the latter. The present experiments examine whether the mnemonic consequences of retrieval are…

Divided attention during encoding typically produces marked reductions in later memory. The attentional boost effect (ABE) is a surprising variation on this phenomenon. In this paradigm, each study stimulus (e.g., a word) is presented along with a target or a distractor (e.g., different colored circles) in a detection task. Later memory is better…

Perhaps the most basic finding in memory research is the repetition effect--the fact that repetition enhances memory. Peterson and Mulligan (2012) recently documented a surprising "negative repetition effect," in which participants who studied a list of cue-target pairs twice recalled "fewer" targets than a group who studied…

Though retrieving information typically results in improved memory on a subsequent test (the testing effect), Peterson and Mulligan (2013) outlined the conditions under which retrieval practice results in poorer recall relative to restudy, a phenomenon dubbed the "negative testing effect." The item-specific-relational account proposes…

One of the foundational principles of human memory is that repetition (i.e., being presented with a stimulus multiple times) improves recall. In the current study a group of participants who studied a list of cue-target pairs twice recalled fewer targets than a group who studied the pairs only once, a negative repetition effect. Such a…

Across 3 experiments, we investigated the factors that dictate when taking a test improves subsequent memory performance (the "testing effect"). In Experiment 1, participants retrieving a set of targets during a retrieval practice phase ultimately recalled fewer of those targets compared with a group of participants who studied the…

Study stimuli presented at the same time as unrelated targets in a detection task are better remembered than stimuli presented with distractors. This attentional boost effect (ABE) has been found with pictorial (Swallow & Jiang, 2010) and more recently verbal materials (Spataro, Mulligan, & Rossi-Arnaud, 2013). The present experiments…

Distraction during encoding has long been known to disrupt later memory performance. Contrary to this long-standing result, we show that detecting an infrequent target in a dual-task paradigm actually improves memory encoding for a concurrently presented word, above and beyond the performance reached in the full-attention condition. This absolute…

The modality-match effect in recognition refers to superior memory for words presented in the same modality at study and test. Prior research on this effect is ambiguous and inconsistent. The present study demonstrates that the modality-match effect is found when modality is rendered salient at either encoding or retrieval. Specifically, in…

Generation enhances item memory but may not enhance other aspects of memory. In 12 experiments, the author investigated the effect of generation on context memory, motivated in part by the hypothesis that generation produces a trade-off in encoding item and contextual information. Participants generated some study words (e.g., hot-___) and read…
