Purpose: Children with speech sound disorders have more difficulties producing speech sounds accurately than same-age peers. In addition, they often have difficulties with speech perception, and weaker phonological awareness skills than their peers and are at risk for negative long-term academic and socio-emotional outcomes. In this tutorial, we…

Addressing the disparate levels of aural skills that students may have acquired through their daily musical experiences prior to formal schooling can be difficult. Placement tests within the Western classical musical tradition typically involve structural decoding and formal concepts of elementary music theory. In this manuscript, we discuss the…

Visual perceptual learning (PL) and perceptual expertise (PE) traditionally lead to different training effects and recruit different brain areas, but reasons for these differences are largely unknown. Here, we tested how the learning history influences visual object representations. Two groups were trained with tasks typically used in PL or PE…

How information is exchanged between the cognitive mechanisms responsible for gaze perception and social attention is unclear. These systems could be independent; the "gaze cueing" effect could emerge from the activation of a general-purpose attentional mechanism that is ignorant of the social nature of the gaze cue. Alternatively, orienting to…

Individuals differ in their ability to draw realistically and these differences can be seen in early childhood, prior to any formal instruction. Some children, considered precocious realists, are able to draw far more realistically than their peers, even if they have never received formal instruction. In this article, the authors describe some of…

Task analytic theories of graph comprehension account for the perceptual and conceptual processes required to extract specific information from graphs. Comparatively, the processes underlying information integration have received less attention. We propose a new framework for information integration that highlights visual integration and cognitive…

A holographic process is presented where the object is made of the real image produced by a two-mirror system. Single-step reflection hologram recording is achieved. Details of the process are given, optics concepts are outlined and demonstrative results are presented. (Contains 6 figures and 2 footnotes.)

Functional neuroimaging research has demonstrated that retrieving information about object-associated colors activates the left fusiform gyrus in posterior temporal cortex. Although regions near the fusiform have previously been implicated in color perception, it remains unclear whether color knowledge retrieval actually activates the color…

The authors of this article state that, as literacy coaches negotiate complex tasks in their work with teachers, they assume dual roles. The authors review the evolution of International Reading Association (IRA) standards, paying particular attention to the roles of literacy coach and literacy coordinator. The authors then present data on the…

Some potential contributions of invariants, heuristics, and exemplars to the perception of dynamic properties in the colliding balls task were explored. On each trial, an observer is asked to determine the heavier of 2 colliding balls. The invariant approach assumes that people can learn to detect complex visual patterns that reliably specify…

Examines project teams and performance-centered design and electronic performance support systems. Topics include performance improvement; technology development; skills; subject expertise; organizational communication; the role-skill paradox; task analysis; and interpersonal communication. (LRW)

A series of experiments introduced interruptions to the execution phase of simple Tower of London problems and found that the opportunity for preparation before the break in task reduced the time cost at resumption. Retrieval of the suspended goal was facilitated when participants were given the opportunity to encode retrieval cues during an…

Reviews phoneme monitoring studies from 1969 to 1996 and groups them in terms of issues addressed with the task, including the contribution of the lexicon to speech perception, processing complexity, attention, contribution of prosodic information, and the basic unit of speech perception. Identifies and highlights task demands and artifactual…

When two masked targets are presented in a rapid sequence, correct identification of the first hinders identification of the second. This attentional blink (AB) is thought to be the result of capacity limitations in visual information processing. Neuropsychological and neuroimaging evidence implicated the right hemisphere as the source of this…

When learning basic color vocabulary, young children show a selective delay in the acquisition of brown and gray relative to other basic color terms. In this study, we first establish the robustness of this finding and then investigate the extent to which perception, language, and color preference may influence color conceptualization.…
