Examined the role of attention in explaining dyadic and triadic joint attention difficulties in autism in three experiments. Found that children with autism were less responsive than developmentally delayed controls in orienting to attention bids and in following a human head-turn cue yet had no difficulty in shifting attention and were faster in…

Replicates and extends the authors' previous research on instructor attire on classroom dynamics. Indicates lesser effects of attire on person perceptions in live interaction as opposed to photographs. Reports that the influence of attire was limited to ratings of instructor extroversion, with no statistically significant interaction between…

Presents a new method that can compare lexical priming (word-word) and sentential priming (sentence-word) directly within a single paradigm. Shows that it can be used to address modular theories of word comprehension, which propose that the effects of sentence context occur after lexical access has taken place. (Author/VWL)

Developed taxonomy of eight types of negation found in children's narratives, and examined children's personal narratives and narratives elicited by picture books. Found most frequent negation to be reference to actions that did not happen. Younger children used negation more than older children, and negation occurred more frequently in personal…

A study investigated the effectiveness of an instructional strategy in teaching 10 elementary-aged students with moderate intellectual disabilities how to shop for groceries. Following the intervention, which consisted of in vivo training using constant time delay and simulation training using a pictorial storyboard, six students achieved…

Discusses three experiments that used a visual version of the syllable monitoring technique to investigate the role of syllabic units in beginning and adult readers. Participants responded whenever a visually presented target syllable appeared at the beginning of a subsequently presented printed word. (Author/VWL)

Three experiments examined cross-modal transfer of shape between touch and vision in 1-month-olds, controlling for side bias and stimulus preference. Results did not provide good evidence that 1-month-olds can transfer information about smooth or nubby shapes from touch to vision. Findings highlight the need to control for side bias and stimulus…

A study investigated whether 32 adolescents with reading disabilities (RD) were slower at processing visual information compared to children of comparable age and reading level, or whether their deficit was specific to the written word. Adolescents with RD demonstrated difficulties in processing rapidly presented verbal and nonverbal visual…

Investigates the role of visual communication in a spoken research genre: the scientific research paper. Analyzes 2,048 visuals projected during 90 papers given at five international conferences in three fields (Geology, medicine, physics), in order to bring out the recurrent features of the visual dimension. (Author/VWL)

This paper reports two experiments that investigated the role of verbal behavior in the emergence and generalization of contextually controlled equivalence classes. During both experiments, participants were trained with two different combinations of the same easily nameable, yet formally unrelated, pictorial stimuli. Match-to-sample baselines for…

This study tested the presence of the face inversion effect in 4-month-old infants using habituation to criterion followed by a novelty preference paradigm. Results of Experiment 1 confirmed previous findings, showing that when 1 single photograph of a face is presented in the habituation phase and when infants are required to recognize the same…

Neurologically normal individuals exhibit strong leftward response biases during free-viewing perceptual judgments of brightness, quantity, and size. When participants view two mirror-reversed objects and they are forced to choose which object appears darker, more numerous, or larger, the stimulus with the relevant feature on the left side is…

Objective: Deficits in executive functioning, including working memory (WM) deficits, have been suggested to be important in attention-deficit/hyperactivity disorder (ADHD). During 2002 to 2003, the authors conducted a multicenter, randomized, controlled, double-blind trial to investigate the effect of improving WM by computerized, systematic…

Young children often have a preference for auditory input, with auditory input often overshadowing visual input. The current research investigated the developmental trajectory and factors underlying these effects with 137 infants, 132 four-year-olds, and 89 adults. Auditory preference reverses with age: Infants demonstrated an auditory preference,…

The concepts of sky and visibility distance, as perceived by different learners, are investigated for the first time as a subject of a science education research. Mental models of students with regard to the subject were elicited. They were interpreted in terms of two-level hierarchy: schemes and facets-of-knowledge (defined in the paper). Our…
