OBJECTIVE Adults diagnosed with attentional deficit disorder (ADHD) are easily distracted in many tasks. Yet ADHD performance on inattentional blindness (IB) tasks has not been examined. Such investigation may aid in discriminating between 3 ADHD models: the neurological model, the perceptual load theory, and the "hunter versus farmer" hypothesis. METHOD Distractibility was assessed in ADHD a...

Teacher noticing of student mathematics thinking, an essential professional competency, has not been sufficiently investigated in China. In this paper, based on four video clips, we combined the frameworks Stockero et al. and Jacobs to analyze characteristics changes 19 prospective teachers’ (PTs) under intervention course “Mathematics Teaching Theory Middle School.” The results showed that (1)...

Analogical reasoning is considered to be a critical cognitive skill in programming. However, it has been rarely studied block-based programming context, especially involving both virtual and physical objects. In this multi-case study, we examined how novice learners majoring early childhood education used analogical while debugging block code make robot perform properly. Screen recordings, scaf...

To test the hypothesis that comparison processes facilitate schema extraction, we studied the effect of making comparisons on 3-year-olds’ ability to perform mapping tasks. In 3 studies, children were tested on their ability to find a hidden toy in a model room after being shown its location in a perceptually different room. In Experiment 1 we found that seeing 2 similar hiding events-permittin...

This article reports a theoretical and experimental attempt to relate and contrast 2 traditionally separate research programs: inattentional blindness and attention capture. Inattentional blindness refers to failures to notice unexpected objects and events when attention is otherwise engaged. Attention capture research has traditionally used implicit indices (e.g., response times) to investigat...

Some effort has been made to examine why people often do not adopt efficient strategies, however little attempt has been made to determine the conditions that support strategy generation. This study examines how practice may lead to efficient strategy generation, through perceptual noticing and the elaboration of a device representation. Forty-three participants were required to complete drawin...
