In order to better understand the neuropsychological underpinnings of the relative strength in word identification in individuals with Down syndrome, the performance of children and adolescents with Down syndrome (N=29) was compared to the performance of a nonverbal-IQ matched group of children and adolescents with developmental disabilities of…

The effects of gaze direction on memory for faces were studied in children from three different age groups (6-7, 8-9, and 10-11 years old) using a computerized version of a task devised by Hood, Macrae, Cole-Davies and Dias (2003). Participants were presented with a sequence of faces in an encoding phase, and were then required to judge which…

The question regarding visual imagery and visual perception remain an open issue. Many studies have tried to understand if the two processes share the same mechanisms or if they are independent, using different neural substrates. Most research has been directed towards the need of activation of primary visual areas during imagery. Here we review…

We examine the visual processing of high-functioning adults with developmental dyslexia (mean Performance IQ=126.5) and current phonological problems. In comparison to an age- and IQ-matched control group, the group with dyslexia showed deficits in two tasks associated with magnocellular/dorsal pathway function. For the "frequency doubling"…

The abilities of 19 adult students with dyslexia and 19 students without dyslexia to recall number facts were compared. Despite being matched for estimated IQ, the dyslexic students were less accurate than the non-dyslexic students when answering subtraction and multiplication questions. When the dyslexic students answered addition and subtraction…

Two experiments were conducted to investigate the effects of multimodal information on learning performance and judgment of learning (JOL). Experiment 1 examined the effects of representation type (word-only versus word-plus-picture) and presentation channel (visual-only versus visual-plus-auditory) on recall and immediate-JOL in fixed-rate…

Current theories of environmental cognition typically differentiate between an online, transient, and dynamic system of spatial representation and an offline and enduring system of memory representation. Here the authors present additional evidence for such 2-system theories in the context of the disorientation paradigm introduced by R. F. Wang…

How long does it take to form a durable representation in visual working memory? Several theorists have proposed that this consolidation process is very slow. Here, we measured the time course of consolidation. Observers performed a change-detection task for colored squares, and shortly after the presentation of the first array, pattern masks were…

Described is Project ADAPT (A Developmental Approach to Psychomotor Transfer), a validated program used with 808 primary grade children, some with learning difficulties, over a 3-year period to enhance academic readiness and self esteem through psychomotor training. An introductory project summary explains program objectives, the needs assessment…

TO BRING TOGETHER DATA RELEVANT TO THE UNDERSTANDING OF HUMAN MOVEMENT WITH PARTICULAR REFERENCE TO LEARNING, THE TEXT SURVEYS THE CONCERN OF SEVERAL DISCIPLINES WITH MOTOR BEHAVIOR AND LEARNING. WORDS AND DEFINITIONS ARE ESTABLISHED, AND THE EVOLUTION OF THE HUMAN ACTION SYSTEM IS DISCUSSED. A CONSIDERATION OF PERCEPTION TREATS THE PROCESS OF…

The book is linked to the annual theme of the 2008 CAERDA International Conference with contributing authors serving as keynote speakers, invited panelists, paper presenters, as well as specialists and educators in the field. The book provides a most comprehensive description of and a theoretically well informed and a scholarly cogent account of…

This paper discusses a mental model of learning based on the processes of attention, perception, processing, and application. The learning process starts with attention, such as curiosity, excitement, expectation, or fear; in pedagogy this is called motivation. New impressions are dependent on and interpreted against the background of previous…

State-of-the-art computers being used today for instructional multimedia products have monitors capable of displaying millions of different colors. Designers are given virtually unlimited control over the factors that govern the display of these colors. This paper examines how color is displayed on computer monitors and interrelationships with how…

This study examined infants' change in visual information pick-up, from an infant-like stimulus-locked visual scanning pattern to an adult-like cognitive control of visual information pick-up. Subjects were 21 children between 25 and 42 months of age. Eye movements were videotaped in a preferential looking situation and later analyzed as still…

This study assessed the bipolarity of cognitive style for 970 clients of the Johnson O'Connor Research Foundation, a vocational guidance service. The 462 male and 508 female examinees were aged 14 to 65 years, with a median age of 24 years. Three cognitive style tests were investigated: (1) the Kagan Matching Familiar Figures Test (KMFFT); (2) the…
