This study investigated whether individual differences in working memory (WM) moderate effects of 2 variations of intervention designed to improve at-risk 4th graders' fraction knowledge. We also examined the effects of each intervention condition against a business-as-usual control group and assessed whether children's measurement interpretation…

This study examined how working memory plays different roles in open-ended versus closed-ended creative problem-solving processes, as represented by divergent thinking tests and insight problem-solving tasks. With respect to the analysis of different task demands and the framework of dual-process theories, the hypothesis was that the idea…

Proficiency in mathematics is a major advantage in industrialised nations. Here we discuss several emotional impediments to mathematics achievement, namely mathematics anxiety and stereotype threat. Synthesising findings from empirical studies in the fields of cognitive, social, and educational psychology, as well as neuroscience, we discuss some…

We tested the limits of working-memory capacity (WMC) of young adults, old adults, and children with a memory-updating task. The task consisted of mentally shifting spatial positions within a grid according to arrows, their color signaling either only go (control) or go/no-go conditions. The interference model (IM) of Oberauer and Kliegl (2006)…

This study compared the relative impact of gender-, race-, and income-based stereotype threat and examined if individuals with multiple stigmatized aspects of identity experience a larger stereotype threat effect on math performance and working memory function than people with one stigmatized aspect of identity. Seventy-one college students of the…

Emotions have important and powerful effects on cognitive processes. Although it is well established that memory influences liking, we sought to document whether liking influences memory. A series of 6 experiments examined whether liking is related to recognition memory for novel music excerpts. In the general method, participants listened to a…

Few educational studies have investigated how well information learned by medical students is retained over time. The primary aim of this study was to investigate how much of the paediatric core curriculum undergraduates remembered a year after originally passing their paediatrics examination. In addition, we looked at whether students'…

The aim of the present study was to (a) extend previous eyewitness research in autism spectrum disorder (ASD) using a live and personally experienced event; (b) examine whether witnesses with ASD demonstrate a facilitative effect in memory for self- over other-performed actions; (c) explore source monitoring abilities by witnesses with ASD in…

The facilitative effect of retrieval practice, or testing, on the probability of later retrieval has been the focus of much recent empirical research. A lesser known benefit of retrieval practice is that it may also enhance the ability of a learner to benefit from a subsequent restudy opportunity. This facilitative effect of retrieval practice on…

The study investigated the effect of selection cues in working memory (WM) on the fate of not-selected contents of WM. Experiments 1A and 1B showed that focusing on 1 cued item in WM does not impair memory for the remaining items. The nonfocused items are maintained in WM even when this is not required by the task. Experiments 2 and 3 showed that…

Memory for words rated according to their relevance in a grassland survival context is exceptionally good. According to Nairne, Thompson, and Pandeirada's (2007) evolutionary-based explanation, natural selection processes have tuned the human memory system to prioritize the processing of fitness-relevant information. The survival-processing memory…

Participants studied category-exemplar pairs ("FRUIT Cherry," "FRUIT Grape") and then practiced some of the items ("Cherry"). In Experiment 1, practice that involved retrieving the item from memory suppressed recall of related items ("Grape"), a finding known as the retrieval-induced forgetting (RIF) effect.…

In the current set of studies, a new hypothesis regarding the cause of the commonly observed U-shaped serial position effect (SPE) in spelling is introduced and tested. Instead of greater competition during output or weaker positional representation for word-medial letters, commonly accepted explanations for the cause of the SPE, the…

BDNF-induced signaling is essential for the development of the central nervous system and critical for plasticity in adults. Mature BDNF signals through TrkB, while its precursor proBDNF employs p75[superscript NTR], resulting in activation of signaling cascades with opposite effects on neuronal survival, growth cone decisions, and synaptic…

The Deese/Roediger-McDermott (DRM) paradigm comprises the study of lists in which words (e.g., bed, pillow, etc.) are all associates of a single nonstudied critical item (e.g., sleep). The probability of falsely recalling or recognising nonstudied critical items is often similar to (or sometimes higher than) the probability of correctly recalling…
