Seeing pictures of objects activates the motor cortex and can have an influence on subsequent grasping actions. However, the exact nature of the motor representations evoked by these pictures is unclear. For example, action plans engaged by pictures could be most affected by direct visual input and computed online based on object shape.…

The aim of this study is to evaluate the efficacy of Montessori education which is offered to upskill the attention gathering skill of children with attention-deficit/hyperactivity disorder. In total fifteen pre-schooler participants, six girls and nine boys who are diagnosed with ADHD (7 of the children with ADHD, 8 with only AD), joined to this…

The Woodcock-Johnson-Fourth edition (WJ IV; Schrank, McGrew, & Mather, 2014a) and the Wechsler Intelligence Scale for Children-Fifth edition (WISC-V; Wechsler, 2014) are two of the major tests of cognitive abilities used in school psychology. The complete WJ IV battery includes the Woodcock-Johnson IV Tests of Cognitive Abilities (Schrank,…

Inhibition of return (IOR) refers to a delay in response time (RT) to targets appearing at a previously cued location. The prevailing view is that IOR reflects visual-motor inhibition. The "attentional momentum" account rejects this idea, and instead proposes that IOR reflects an automatic shift of attention away from the cued location…

A series of experiments provided converging support for the hypothesis that action preparation biases selective attention to action-congruent object features. When visual transients are masked in so-called "change-blindness scenes," viewers are blind to substantial changes between 2 otherwise identical pictures that flick back and forth. The…

This literature review focuses on the confirmed, suspected, and speculative effects of violent and non-violent video game exposure on negative and positive outcomes. Negative outcomes include aggressive feelings, aggressive thoughts, aggressive behavior, physiological arousal, and desensitization, whereas positive outcomes include various types of…

Tested visual-perceptual, attentional, and visual-motor skills of 16 school-age children who had been born pre-term and "healthy," and 16 who had been born full-term. Found that compared to subjects born full-term, pre-term subjects performed well on most visual perception tasks, but less well on visual search and visual-motor tasks.…

Visual-spatial orienting in 10 high-functioning adults with autism was examined. Compared to controls, subjects responded faster to central than to lateral stimuli, and showed a left visual field advantage for stimulus detection only when laterally presented. Abnormalities in attention shifting and coordination of attentional and motor systems are…

Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being…

Multielement visual tracking and visual search are 2 tasks that are held to require visual-spatial attention. The authors used the attentional operating characteristic (AOC) method to determine whether both tasks draw continuously on the same attentional resource (i.e., whether the 2 tasks are mutually exclusive). The authors found that observers…
