This article discusses the successes of behavior analysts in affecting challenging behaviors in persons with developmental disabilities. Three future issues are then addressed: the development of challenging behaviors, the role of rule-governance in challenging behavior, and the behavior of persons who directly apply functional assessment and…

Trained preschoolers and adults on three sets of successive discriminations with stimuli labeled A, B, and R. Tested for derived stimulus-response relations and stimulus-stimulus relations. Adults displayed class-consistent B-R and A-B performances over all conditions. Children's display of class-consistent B-R performance varied by training…

A study of the reading competence of 25 visually impaired pupils in Sweden followed subjects from 1988 to 1991. Neither visual acuity, reading media, optical aids, nor reading distance were clearly related to reading competence. Rather, good readers were students who scored higher on verbal cognitive tests and had a greater interest in reading as…

Reports on the performance of the vector space model in the presence of OCR (optical character recognition) errors in information retrieval. Highlights include precision and recall, a full-text test collection, smart vector representation, impact of weighting parameters, ranking variability, and the effect of relevance feedback.

Studied the effect of homelessness on cognitive and academic functioning of children 6 to 11 years old in comparison to a control group of housed children in the same classroom. Found no differences in cognitive functioning between homeless and housed children, but did find that homeless children performed significantly more poorly than housed…

A study on the use of performance indicators within a quality assurance system in higher education in the Netherlands is reported. The case study of seven departments of economics shows the attention paid to structural aspects of the curriculum instead of the declared object of the program evaluation. (SLD)

Students from 38 colleges with high scores on an advanced placement examination essay and low scores on the multiple-choice portion were compared with students with the opposite pattern. The pattern was not related to college grades, but was related to other test performance. (SLD)

This article reviews key findings from school-reform studies of the 1980s on sustained use of effective teacher practices in the classroom and explains their relevance to special education. Recent findings are also highlighted and unresolved issues are identified. An appendix lists sustainability factors and issues. (Contains references.)…

This article discusses newer views of functional developmental plasticity occurring after biological insults to the developing central nervous system (CNS), including concepts of neurobehavioral outcome and ways to measure it, biological risk, age and development at onset of CNS insult, time since onset of CNS insult, and reserve. (Contains…

This article analyzes variables associated with adherence by parents to recommendations designed to solve common childhood problems and specific corresponding processes that are responsible for poor adherence. Adherence variables include establishing operations, stimulus generalization, response acquisition, and consequent events. (Contains…

Three experiments examined kindergartners' and second graders' retention in the context of two distinctiveness manipulations, the von Restorff and bizarre imagery paradigms. Results showed that: older children retained more information from lists of pictures or interactive images over 3 weeks than younger; younger children failed to benefit from…

Discusses what is known about cooperative performance incentive (CPI) plans, which are award programs that offer teachers and other school staff pay bonuses for achievement of specific schoolwide educational objectives. The paper describes and compares existing CPI models worldwide, analyzes their impact on student learning and school practices,…

A study identified social, educational, and demographic characteristics of 30 postsecondary students who demonstrated strong reading and writing skills. Factors included were parental involvement in early education and educational decisions, extensive family communication, early exposure to and intensive experiences with reading and writing, and…

The project DEVISE case study shows how diversity modeling can be used as a powerful design tool. Designers used performance-centered design techniques to create a virtual learning environment in which students with learning disabilities would be more fully supported with an interface that meets their needs.

Two experiments tracked infants' eye movements to examine use of word-initial information to understand fluent speech. Results indicated that 21- and 18-month-olds recognized partial words as quickly and reliably as whole words. Infants' productive vocabulary and reaction time were related to word recognition accuracy. Results show that…
