Music performance requires high levels of motor control. Professional musicians use body movements not only to accomplish and help technical efficiency, but to shape expressive interpretation. Here, we recorded motion and audio data of twenty participants performing four musical fragments varying in the degree of technical difficulty to analyze…

Recent literature places more emphasis on assessment comments rather than relying solely on scores. Both are variable, however, emanating from assessment judgements. One established source of variability is "contrast effects": scores are shifted away from the depicted level of competence in a preceding encounter. The shift could arise…

Two experiments investigated how people use buildings and street configurations to reorient in large-scale environments. In immersive virtual environments, participants learned objects' locations in an intersection consisting of 4 streets. The objects' locations were specified by 2 cues: a building and/or the street configuration. During the test,…

For adults, "no" and "not" change the truth-value of sentences they compose with. To investigate children's emerging understanding of these words, an experimenter hid a ball in a bucket or a truck, then gave an affirmative or negative clue (Experiment 1: "It's not in the bucket"; Experiment 2: "Is it in the…

This study aimed to investigate how Grade 1-2 English language learners (ELLs) differ in their performance on a writing test in two test modes: paper and online. Participants were 139 ELLs in the United States. They completed three writing tasks, representing three test modes: (1) a paper in which students completed their writing using a…

The music industry is built on a system of expert evaluation focused on sound, but the foundations are challenged by recent research, which suggests that sight trumps sound. This presents a challenge to music educators, who train the next generation of expert performers and listeners. The aim of this study is to investigate students' perceptions…

The olfactory span task (OST) uses an incrementing non-matching to sample procedure such that the number of stimuli to remember increases during the session. The number of consecutive correct responses (span length) and percent correct as a function of the memory load have been viewed as defining rodent working memory capacity limitations in…

Potential relations between gaze cueing, social use of gaze, and ability to follow line of sight were examined in children with autism and typically developing peers. Children with autism (mean age = 10 years) demonstrated intact gaze cueing. However, they preferred to follow arrows instead of eyes to infer mental state, and showed decreased…

The simple act of repeatedly looking left and right can enhance subsequent cognition, including divergent thinking, detection of matching letters from visual arrays, and memory retrieval. One hypothesis is that saccade execution enhances subsequent cognition by altering attentional control. To test this hypothesis, we compared performance…

When task-switching studies use the task-cuing procedure with a 1:1 cue-task mapping, task switching and cue switching are confounded, which is problematic for interpreting switch costs. The use of a 2:1 cue-task mapping is a potential solution to this problem, but it is possible that introducing more cues may also introduce marked changes in…

Twenty male adults with ADHD, 16 dyslexic adults, 15 comorbid adults, and 16 normal controls were compared on performance and underlying brain responses, during a cued Continuous Performance Test (O-X CPT), with the aim of discovering features of information processing differentiating between the groups. The study evaluated both cue- and…

The purpose of this study was to investigate and compare the mechanisms of brain activity, as revealed by a combination of the visuospatial attention shifting paradigm and event-related potentials (ERP) in children with developmental coordination disorder (DCD) and typically developing children. Twenty-eight DCD children and 26 typically…

Four studies compared preschoolers' fast mapping of new proper and common names following indirect exposures requiring inference with their learning new names following ostensive cues. Found that inferential learning of names and learning by direct instruction were largely equivalent: learning from a situation with clear joint references…

Two studies examined efficacy of context reinstatement in enhancing 5- to 7-year olds' recall. Results showed that children exposed to a context reminder 24 hours before the six-month interview and children interviewed in the event context did not differ but reported significantly more information than children in standard interview.

This paper reports on a study on the relationship between cognitive task complexity and linguistic performance in L2 writing. In the study, two models proposed to explain the influence of cognitive task complexity on linguistic performance in L2 are tested and compared: Skehan and Foster's Limited Attentional Capacity Model (Skehan, 1998; Skehan…
