Previous models of agraphia have been descriptive and have emphasized the association of agraphia with other disorders such as aphasia and alexia. Such models have frequently led to inconsistent descriptions of specific agraphia types. These inconsistencies have made clinical-anatomical correlations difficult. Recent studies of agraphic patients with focal cerebral lesions have made it possible to develop a new model of writing based on specific neuropsychological mechanisms. In addition, results from computerized tomography have helped delineate probable anatomic substrates for many of these mechanisms. It is hoped this model provides a means for a better understanding of the mechanisms and anatomy underlying the agraphias as well as a better understanding of the relationships of the agraphias with aphasia and alexia.

The various anomalies which occur in the writing of people with right brain damage are described. They are compared with the reading and drawing impairments that these patients also show. In particular, the phenomenon of unilateral visual neglect is analyzed and hypotheses as to the nature of this disorder are put forward.

Two experiments examined the way in which kindergarteners, first graders, and adults spell syllables like /spa/, /sta/, and /ska/. The second consonants of these syllables are standardly spelled as the voiceless stops P, T, and C/K. From a phonetic standpoint, however, the consonants could be spelled as the voiced stops B, D, and G. The proportion of voiced spellings was found to decrease with reading level: The nonstandard spellings were fairly prevalent among children, but almost nonexistent among adults. Nonetheless, most adults could choose the phonetically plausible voiced spellings over phonetically incorrect spellings.

This research investigated the effects of microcomputer technology on the acquisition of writing and reading skills in 32 deaf children between the ages of 3.2 and 8.5 years. The children used a special interface keyboard which builds in perceptual salience and animation of color pictures and graphic representations of signs from American Sign Language (ASL). The learning mechanism underlying this novel instructional system is responsive, interactional, and exploratory, reflective of the way in which most children acquire a first language. Results have demonstrated improvement in writing, reading, and general communication skills. These advances are attributed to exploratory learning -not solely programmed instruction – which allows the child to investigate at will the representation of various printed forms which relate to the child's own primary mode of communication.

Researchers who study the writing process have found that beginning writers do little spontaneous revising of their own texts. This study explores the possibility that beginning writers do not revise because they do not read their own writing. The assumption behind the study is that explicit self-questioning strategies would engage young writers in reading their texts; thus they would become more active revisers. The experimental intervention is a question-prompt computer program (added to a word processing program) that guides the 11 to 16-year-old subjects to examine their own writing by asking themselves questions about their texts. This process was intended to engage the subjects in reading the text closely and revising more extensively. Analyses of the number and nature of revisions indicate that self-reflective question-prompts engage students in reading their texts and lead to significant changes in revising strategy.

We investigated the development in preschoolers' conceptualization of the written system from its graphic rendering and its mapping onto meaning by analyzing children's writings and readings of their writings. Forty-two Israeli children aged 3.4 – 5.8 years were asked to draw, write, and interpret a number of utterances. By the age of four, children's writings became constricted in size relative to their drawings and were composed of linearly organized units separated by regular blanks. These units increased in their adherence to conventional Hebrew letters throughout the age range examined. Children's interpretations of their own writing were classified into five modes: Interpretation unrelated to the utterance; preserving the content of the utterance but not its verbal form; complete reiteration; dividing the utterance into phonetic units; and description of the written characters. These modes were related to age and to conventionality of characters used.
