Limits in visual working memory (VWM) strongly constrain human performance across many tasks. However, the nature of these limits is not well understood. In this article we develop an ideal observer analysis of human VWM by deriving the expected behavior of an optimally performing but limited-capacity memory system. This analysis is framed around…

Children's acquisition of tool use abilities is an important part of development but is not yet well understood. This study compares two modes of tool-use learning, observation and individual haptic experience. Two- and 3-year-olds had haptic experience with tools, observed tool use by others, had both haptic and observational experience, or no…

Body movement provides a rich source of cues about other people's goals and intentions. In the present research, we investigate how well people can distinguish between different social intentions on the basis of movement information. Participants observed a model reaching toward and grasping a wooden block with the intent to cooperate with a…

In the education community, the Technological Pedagogical Content Knowledge (TPACK) framework has become a popular construct for examining the types of teacher knowledge needed to achieve technology integration. In accordance with Katz and Raths's 'Goldilocks Principlen' (cited in Kagan, 1990), TPACK, with its seven knowledge domains, may be too…

There are many different approaches to intervention aimed at facilitating the social and communicative abilities of children with Autistic Spectrum Disorders (ASD). Behavioural interventions seek to improve the social and communicative abilities of children with ASD through interaction. Recently there has been a move towards naturalistic…

We evaluated the effects of a training package, including instructions, modeling, rehearsal, and feedback, for training staff members to conduct mand training with children. Experimenters collected data on staff performance on each step of a task analysis of mand training and on unprompted child vocal mands. Training resulted in increases in staff…

Psychophysical reverse-correlation methods such as the "classification image" technique provide a unique tool to uncover the internal representations and decision strategies of individual participants in perceptual tasks. Over the past 30 years, these techniques have gained increasing popularity among both visual and auditory psychophysicists.…

Research pertaining to science museum exhibit design tends to be articulated at a level of generality that makes it difficult to apply in practice. To address this issue, the present study used a design-based research approach to understand the educational potential of a biology exhibit. The exhibit was considered an educational environment which…

The role of anticipatory auditory imagery in music-like sequential action was investigated by examining timing accuracy and kinematics using a motion capture system. Musicians responded to metronomic pacing signals by producing three unpaced taps on three vertically aligned keys at the given tempo. Taps triggered tones in two out of three blocked…

Example-based learning has been studied from different perspectives. Cognitive research has mainly focused on "worked" examples, which typically provide students with a written worked-out didactical solution to a problem to study. Social-cognitive research has mostly focused on "modeling" examples, which provide students the opportunity to observe…

We study project-based, technology-enhanced learning environments in higher education, which should produce, by means of specific mechanisms, learning outcomes in terms of transferable knowledge and learning-, thinking-, collaboration- and regulation-skills. Our focus is on the role of objects from professional practice serving as boundary objects…

Objective: To measure test-retest reliability of the Stop-Signal Task (SST) and the Conners' Continuous Performance Test (CPT) in children with ADHD. Methods: 12 children with ADHD (age 11.46 plus or minus 1.66) participated in the study. Primary outcome measures were stop-signal reaction time (SSRT) for the SST and CPT's commission errors (%FP).…

Given Russian students' general lack of group work and opportunities to develop student responsibility in their prior schooling experiences, the purpose of this study was to examine how a group of Russian high school students responds to novel demands of participation in a sport education season. Forty-two students from two ninth-grade physical…

Tasks with adult learners have been discussed extensively in the language learning literature whilst studies about children using tasks are less widespread. Children's ability to interact on tasks with each other grows steadily with age. This paper reports on the differences observed in the interactions of 10-year-old children and adult learners.…
