Here, we assess whether quantity representations are influenced by the perceptual biases hypothesized to manifest in depressive individuals. In contrast to this clinical model, several prominent models of numerical cognition assume that quantity representations are abstract, and therefore are independent of the items that are being quantified. If…

Item recognition and temporal order memory follow different developmental trajectories during middle childhood, with item recognition performance stabilizing and temporal order memory performance continuing to improve. We investigated the potential unique role of individual executive functions on item recognition and temporal order memory during…

A growing body of research has found a relationship between parenting and the development of executive function in young children; however, fewer studies have examined how parenting is related specifically to the development of working memory. Using data from the Family Life Project, this study examined whether attention was a pathway through…

List-method directed forgetting usually involves asking people to study a list, followed by a cue to forget it, and then studying a second list. Prior work suggests that List 2 encoding is necessary for directed forgetting to occur, but recent studies have found that moving the forget cue from List 1 to List 2 allows people to selectively forget…

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…

Stimuli presented with targets during a monitoring task are better remembered than stimuli presented with distractors, a result referred to as the attentional boost effect (ABE). The ABE is consistently found for item memory, but conflicting results have been reported for different assessments of associative memory, with studies of source memory…

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…

The testing effect is 1 of several memory effects moderated by experimental design, such that the effect on free recall is larger in a mixed-list than pure-list design (Mulligan, Susser, & Smith, 2016). The current experiments assess hypotheses regarding why this pattern is found. Three extant accounts of design effects (Nguyen & McDaniel,…

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)…

The majority of research on metamemory focuses on retrospective memory: memory for past events. Prospective memory, in contrast, refers to the process of remembering to carry out intentions in the future. Despite claims that metacognition is essential to prospective remembering, it is unclear whether the metamemorial effects that researchers have…

Although memory retrieval often enhances subsequent memory, Peterson and Mulligan (2013) reported conditions under which retrieval produces poorer subsequent recall--the negative testing effect. The item-specific--relational account proposes that the effect occurs when retrieval disrupts interitem organizational processing relative to the restudy…

The typical pattern of results in divided attention experiments is that subjects in a full attention (FA) condition perform markedly better on tests of memory than subjects in a divided attention (DA) condition which forces subjects to split their attention between studying to-be-remembered stimuli and completing some peripheral task.…

Experience-based cues, such as perceptual fluency, have long been thought to influence metacognitive judgments (Kelley & Jacoby, 1996; Koriat, 1997). Studies found that manipulations of perceptual fluency via changes in font and volume alter Judgments of Learning (JOLs) without influencing memory performance (Rhodes & Castel, 2008, 2009).…

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…
