Three groups of eight Ss (Down's syndrome, CA control, and MA control) received a battery of tests to assess recall and recognition memory using either auditory or visual input with verbal and nonverbal responses. Results indicated that the Down's syndrome group possessed deficits in both storage and retrieval abilities, with storage of visually…

Three studies used computer graphics and/or verbal questioning to examine beliefs among children and adults that vision involves input to the eyes (intromission) or emissions from the eye (extramission). Results showed decreases in extramission and increases in intromission beliefs across age. There were more extramission interpretations with…

Four experiments tested the hypothesis that the importance of linguistic labels for young children's conceptual organization stems from a privileged processing status of auditory input over visual input. Findings indicated that when auditory and visual stimuli were presented separately, 4-year-olds were likely to process both kinds of stimuli,…

Three analyses were conducted to assess the effects of different consequent stimuli on the stereotypical and self-injurious behavior of two children with severe developmental disabilities and dual sensory impairments. Contingent presentation of the specially selected stimuli plus response interruption resulted in more suppression than contingent…

Twenty congenitally blind infants were placed in a panelled framework with various tactile and auditory objects for 20-minute periods. Results indicated that subjects improved their performance of spatially related activities when exposed to an environment helping them understand the concept and permanence of objects and the production of…

Two experiments examined infants' reliance on object shape versus color for word generalization to animate and inanimate objects. Infants were taught labels for either novel vehicles or novel animals using preferential-looking procedure or an interactive procedure. Results of both experiments indicated that infants limited their word…

Two studies investigated whether an appropriate versus an inappropriate hemisphere alluding stimulation treatment of children with L-type dyslexia produces differential reading effects, and effects of hemisphere specific stimulation on children with L-, P-, and M-type dyslexia. Results support the validity of dyslexia subtyping and the…

Investigates the effects of audiovisual media on preschool children's attitudes toward music presentations from "The Lion King" and "Fantasia." Finds that the listening times for music-plus-video presentations of both selections were longer and a majority of the children expressed a preference for "The Lion King" over "Fantasia." (CMK)

Two experiments examined role of affective correspondence between signal and outcome in 4-month olds' associative learning. Found that only when consoling infant-directed speech signaled the sad face did infants' visual interest in a checkerboard increase. Arousing infant-directed speech signaling either the smiling or sad face produced positive…

Two experiments tested a neo-Piagetian model of verbal short-term memory, comparing it with the articulatory loop model. Findings indicated that the proposed model accounted for effects of M capacity, word length, and presentation modality on short-term memory. The model's fit to the data was acceptable, and parameter estimates were consistent…

Stimulus preference assessments for individuals with developmental disabilities typically involve offering choices among stimuli and providing immediate access to the chosen stimuli. Several researchers have explored the utility of presenting choices verbally, thereby obviating the need to present the choices in tangible form and deliver access to…

Examinations of interference between verbal and visual materials in working memory have produced mixed results. If there is a central form of storage (e.g., the focus of attention; N. Cowan, 2001), then cross-domain interference should be obtained. The authors examined this question with a visual-array comparison task (S. J. Luck & E. K. Vogel,…

The present study examined continuous and discrete bimanual drumming in response to different instructions in 10 adults with Down syndrome, 10 mental age-matched and 10 chronological age-matched groups. For continuous drumming, participants hit two drums with both hands at the same time following verbal (e.g., "up" and "down"), visual (e.g., video…

The Picture Exchange Communication System (PECS) is an augmentative and alternative communication program (Frost & Bondy, 2002). Although PECS has been effectively used to teach functional requesting skills for children with autism, mental retardation, visual impairment, and physical disabilities (e.g., Anderson, Moore, & Bourne, 2007; Chambers &…

Researches have showed that joke telling is a type of verbal behavior associated with the field of sociolinguistics (e.g., Al-Khatib, 1999). This study aims to report Taiwanese jokes and their sociological functions that people in Taiwan attempt to communicate in jokes. Besides, this study will report what the typical topics and characteristics…
