Comprehension of an illustrated document can involve complex visual scanning in order to locate the relevant information on the screen when this is evoked in spoken explanations. The present study examined the effects of two types of attention-guiding means (color change or step-by-step presentation of diagram elements synchronized with a spoken…

This study examined empirical and theoretical differences and similarities between attention deficit hyperactivity disorder (ADHD) and child temperament in 32 ADHD children aged 6-11 years, and a comparison group of 23 children with similar sociodemographic characteristics. Children were assessed for ADHD symptoms (hyperactivity, impulsivity, and…

The aim in the current study was to investigate the early development of joint attention, eye contact and affect during the first 2 years of life, by using retrospective parental interviews and analyses of home videos of infants who were later diagnosed with Autistic Disorder (AD). The 36 children with AD and the 27 matched control children were…

Three variables (diagnosis, location of cues, and mental age of learners) influencing stimulus control and stimulus overselectivity were assessed with eight autistic children (mean age 12 years) and eight average children matched for mean age. Among results were that autistic subjects tended to respond overselectively only in the extra-stimulus…

Power Spectral Fast Fourier analysis of the scalp electroencephalogram was obtained from six locations in 69 children with learning disabilities without hyperactivity and 34 control children, during baseline and while performing reading, arithmetical, and spatial tasks. Significant EEG power and percent differences for specific frequencies were…

The contribution that attentional factors, listener biases, and other nonsensory variables make to stimulus dominance in a dichotic listening task was assessed by comparison of scores obtained in a conventional two-ear monitoring task and a yes/no target-monitoring task. Results suggested that nonsensory factors had little influence in determining…

A load theory of attention in which distractor rejection depends on the level and type of load involved in current processing was tested. A series of experiments demonstrates that whereas high perceptual load reduces distractor interference, working memory load or dual-task coordination load increases distractor interference. These findings…

When observers are presented with 2 targets in rapid succession, identification of the 1st is highly accurate, whereas identification of the 2nd is impaired at brief intertarget intervals (i.e., 200-500 ms). This 2nd-target deficit is known as the attentional blink (AB). According to bottleneck models, the AB arises because attending to the 1st…

We compared results of descriptive and functional analyses of problem behavior for 12 participants whose descriptive data have been reported previously (Thompson & Iwata, 2001). Results indicated that in only 3 of the 12 cases was problem behavior maintained by the consequence observed most frequently during the descriptive analysis. Attention was…

Two experiments tested predictions of the hemispheric coactivation model for redundancy gain (J. O. Miller, 2004). Simple reaction time was measured in divided attention tasks with visual stimuli presented to the left or right of fixation or redundantly to both sides. Experiment 1 tested the prediction that redundancy gain--the decrease in…

Memory impairment is a core feature in schizophrenia (SZ). The aim of this study was to investigate short-term memory (STM) and its sensitivity to distraction with visual-spatial material. This study comprised 23 recent-onset SZ patients and 23 healthy controls. The degree of disruption upon recall from interleaving irrelevant items within a…

Pain catastrophizing is generally viewed as an important cognitive factor underlying chronic pain. The present study examined personality and temperament correlates of pain catastrophizing in a sample of young adolescents (N = 132). Participants completed the Pain Catastrophizing Scale for Children, as well as scales for measuring sensitivity of…

The relationship between severe early institutional deprivation and scholastic attainment at age 11 in 127 children (68 girls and 59 boys) adopted from institutions in Romania was compared to the attainment of 49 children (17 girls and 32 boys) adopted within the UK from a non-institutional background. Overall, children adopted from Romania had…

Thirty preschool children (10 typically developing, 10 intellectually disabled and 10 hearing impaired) were videotaped during play. Data was collected for each participant group, covering the number, length and nature of social engagement opportunities (SEOs) and the children's attentional states during SEOs. The typically developing group had…

A recent meta-analysis found that across studies individual differences in aspects of children's emotionality predict social status [Dougherty, L.R., (2006). Children's emotionality and social status: a meta-analytic review. Social Development, 15, 394-417.]. In the present study we extended these findings by examining the emotion of interest and…
