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…

Fifty years ago, Mednick ["Psychological Review", 69 (1962) 220] proposed an elaborate model that aimed to explain how creative ideas are generated and why creative people are more likely to have creative ideas. The model assumes that creative people have flatter associative hierarchies and as a consequence can more fluently retrieve…

Although early studies of executive functioning in children supported Miyake et al.'s (2000) three-factor model, more recent findings supported a variety of undifferentiated or two-factor structures. Using a cohort-sequential design, this study examined whether there were age-related differences in the structure of executive functioning among…

Collaboration is an important aspect of information systems (IS) education since work is typically performed in teams. However, IS students often do not fully appreciate the value of group work in their business courses. This teaching tip describes an activity that will objectively demonstrate the value of collaboration and diversity of…

Interviews and participant observation are commonly used to explore the experience of dementia, yet may not adequately capture perspectives of persons with dementia as communication changes. We used photovoice (i.e., using cameras in qualitative research) along with interviews and participant observation to explore meanings of leisure for persons…

This article describes how researchers take a multidisciplinary approach to investigating how middle grades students learn science vocabulary. The authors investigated teaching strategies for increasing retention of science vocabulary with seventh graders and stumbled upon an interesting finding that was not even a target for their study, yet it…

Individuals with Down syndrome tend to have a marked impairment of verbal short-term memory. The chief aim of this study was to investigate whether phonemic discrimination contributes to this deficit. The secondary aim was to investigate whether phonological representations are degraded in verbal short-term memory in people with Down syndrome…

The influence of top-down cognitive control on 2 putatively distinct forms of distraction was investigated. Attentional capture by a task-irrelevant auditory deviation (e.g., a female-spoken token following a sequence of male-spoken tokens)--as indexed by its disruption of a visually presented recall task--was abolished when focal-task engagement…
