The present study evaluated the effects of stimulus complexity and rule usage on a visual perspective-taking task. Preschoolers, first, third, and fifth graders, and adults were shown arrays of dolls and performed a series of perspective-taking tasks. Errors decreased with age, and more errors occurred with the more complex visual arrays. A significant number of errors were made in self-view tr...

An experiment examined visual performance in a simulated luggage-screening task. Observers participated in five sessions of a task requiring them to search for knives hidden in x-ray images of cluttered bags. Sensitivity and response times improved reliably as a result of practice. Eye movement data revealed that sensitivity increases were produced entirely by changes in observers' ability to r...

Children with visual impairments (CWVI) generally perform poorer in gross motor skills when compared with their sighted peers. This study examined the influence of age, sex, and severity of visual impairment upon locomotor and object control skills in CWVI. Participants included 100 CWVI from across the United States who completed the Test of Gross Motor Development II (TGMD-II). The TGMD-II co...

BACKGROUND Personal social network and coping skills have important influences on suicidality of young people and such influences must be understood in the context of other factors.

In the present article we will review results from a number of studies conducted in our laboratory where the purpose has been to examine phonological processing capabilities in deafened adults and individuals with a severe hearingimpairment, and to relate their phonological processing skills to visual and audio-visual speech understanding performance. The results show that deafened adults and i...

Computer science students contemplating a career in graphics need to develop a visual sense, but traditional course topics do not meet this need. Visual analysis is a teaching technique developed for computer science instructors that helps impart this ability. Through the use of a few visual cues, students learn to visually identify surface algorithms, shaders and lighting techniques. An intera...

OBJECTIVE This study examined mothers' and fathers' perceptions of effective and ineffective communication by nurses in the neonatal intensive care unit (NICU) environment, using communication accommodation theory (CAT) as the framework. METHODS Twenty mothers and 13 fathers participated in a semi-structured interview about their perceptions of effective and ineffective communication with nur...
