This study explored the relationship between traditional item difficulty and cognitive complexity as measured by response time. Rural students (n=43) responded to computer-based tests of the Individualized Study by Technology General Mathematics Course developed by Alaska's Department of Education. Results indicated that mean response times were…

The time required for 96 children (ages 8-15) with and without learning disabilities to interpret emotions based on from facial expressions, and the accuracy of those interpretations, were investigated. Children with learning disabilities were less accurate and spent more time identifying specific emotions. Both age and sex influenced response…

Examines the characteristics of surface dyslexia in Italian, a language with high grapheme-phoneme correspondence. Reading performances of four boys are reported. (Author/VWL)

Background: Williams syndrome (WS) and Down syndrome (DS) are two neurodevelopmental genetically based disorders which exhibit mental retardation with a unique cognitive profile. Naming in individuals with WS and DS has been investigated in several studies, with results indicating that the performance of children with WS and DS is at a similar…

This study investigated the encoding of syllable boundary information during speech production in Dutch. Based on Levelt's model of phonological encoding, we hypothesized segments and syllable boundaries to be encoded in an incremental way. In a self-monitoring experiment, decisions about the syllable affiliation (first or second syllable) of a…

Children (ages 5, 7, and 9 years) and young adults completed two visual attention tasks that required them to make a forced choice identification response to a target shape presented in the center of a computer screen. In the first task (high correlation condition) each target was flanked with the same distracters on 80% of the trials (valid…

The relationships between response latencies and accuracy on the matching familiar figures test (MFFT) and two gross motor tasks (batting or catching a ball) were studied in twenty-nine 9-year-old boys. Children were classified into four groups using a double dichotomy of response latencies and errors on the MFFT: reflective, impulsive,…

Recent debate regarding dual-task performance has focused on whether costs result from limitations in central capacity, and whether central operations can be performed in parallel. While these questions are controversial, the dominant models of dual-task performance share the assumption that central operations are generic--that is, their…

Three children with autism were taught to identify pictures of emotions in response to their spoken names. Their speed of acquisition was compared using a within-child alternating treatments design across three teaching conditions, each involving a 5 second delay to reinforcement. In the marked-before condition, an instruction encouraged the…

The response of military psychology in times of war or other great public crises may presage the success of the profession in less perilous times. The ability of public-sector psychologists to provide assistance and improve the common welfare during conflict or turmoil is generally followed by an increased demand for psychological services. This…

To explore how online speech processing efficiency relates to vocabulary growth in the 2nd year, the authors longitudinally observed 59 English-learning children at 15, 18, 21, and 25 months as they looked at pictures while listening to speech naming one of the pictures. The time course of eye movements in response to speech revealed significant…

The purpose of this study was to assess the influence of phonological priming on the speech reaction time (SRT) of children who do (CWS) and who do not (CWNS) stutter during a picture-naming task. Participants were eighteen 3-5-year-old CWS (M = 50.67 months, SD= 11.83 months), matched in age and gender with 18 CWNS (M = 49.44 months, SD = 10.22…

What brain mechanisms underlie autism, and how do they give rise to autistic behavioral symptoms? This article describes a neural model, called the Imbalanced Spectrally Timed Adaptive Resonance Theory (iSTART) model, that proposes how cognitive, emotional, timing, and motor processes that involve brain regions such as the prefrontal and temporal…

It has been observed that students react in similar ways to mathematics and science tasks that differ with regard either to their content area and/or to the type of reasoning required, but share some common, external features. Based on these observations, the Intuitive Rules Theory was proposed. In this present study the framework of this theory…

Several research laboratories have found that instructed behavior can be less sensitive to changes in contingencies than shaped behavior. The current experiment examined whether these differences in sensitivity could be related to resistance to change. Two groups of subjects, who were matched on the basis of an initial disruption assessment, were…
