In a recent PNAS article, Chan and LaPaglia (2013) provided arguments and evidence to support the claim that reactivating a witnessed memory (by taking a test) renders the memory labile and susceptible to impairment by subsequent misinformation. In the current article, we argue that Chan and LaPaglia's (2013) findings are open to alternative…

Evidence suggests that some cognitive processes are based on sensorimotor systems in the brain (embodied cognition). The premise of this is that "Biological brains are first and foremost the control systems for biological bodies". It has therefore been suggested that both online cognition (processing as we move through the world) and…

Two studies examined the effectiveness of a flashcard-based study strategy, "Flashcards-Plus," in an ecologically valid context. The strategy requires students to create flashcards designed to increase their ability to retain, comprehend, and apply textbook material to exams. In Studies 1a (n = 73) and 1b (n = 62), we introduced all…

This study targeted to explore the effect of memory strategy on EFL learners' vocabulary retention with a consideration of learners' multiple intelligences. In this study, the memory strategy consisted of three parts of grouping, acronym and images. The participants of this study were 80 male and female EFL learners of intermediate level who…

The present research explored the effects of restraint stress on two situations involving incentive downshift: consummatory successive negative contrast (cSNC) and extinction of escape behavior in the Barnes maze. First, Experiment 1 confirmed that the restraint stress procedure used in these experiments increased levels of circulating…

The placebo effect is any outcome that is not attributed to a specific treatment but rather to an individual's mindset (Benson & Friedman, 1996). This phenomenon can extend beyond its typical use in pharmaceutical drugs to involve aspects of everyday life, such as the effect of sleep on cognitive functioning. In 2 studies examining whether…

In an age of PowerPoint, much everyday public communication is semantically organized as an expository presentation. This contrasts with traditional approaches such as storytelling that are episodically organized and presented as narratives. The constructivist theory of narrative comprehension, along with other theoretical perspectives, suggests…

Prospective memory (PM) research typically examines the ability to remember to execute delayed intentions but often ignores the ability to forget finished intentions. We had participants perform (or not perform; control group) a PM task and then instructed them that the PM task was finished. We later (re)presented the PM cue. Approximately 25% of…

The effects of high- versus low-quality child care during 2 developmental periods (infant-toddlerhood and preschool) were examined using data from the National Institute of Child Health and Human Development Study of Early Child Care. Propensity score matching was used to account for differences in families who used different combinations of child…

Retrieving memories can impair recall of other related traces. Items affected by this retrieval-induced forgetting (RIF) are often less accessible when tested with independent probes, a characteristic known as cue independence. Cue independence has been interpreted as evidence for inhibitory mechanisms that suppress competing items during…

According to the constructive episodic simulation hypothesis (Schacter & Addis, 2007), both remembered past and imagined future events rely heavily on episodic memory. An alternative hypothesis is that observed similarities between remembering and imagining reflect the influence of broader factors such as descriptive ability, narrative style,…

Studies suggest motor deficit asymmetry may help predict the pattern of cognitive impairment in individuals with Parkinson disease (PD). We tested this hypothesis using a highly validated and sensitive spatial memory task, spatial delayed response (SDR), and clinical and neuroimaging measures of PD asymmetry. We predicted SDR performance would be…
