Despite the importance of written expression to the lives of individuals with autism spectrum disorders (ASD), there is limited research on teaching writing skills to this population. In the current study, we used a multiple probe across behaviors design to evaluate the effects of simultaneous prompting (SP) and computer-assisted instruction (CAI)…

This replication study focused on the effectiveness of two different intervention approaches, activity-based intervention and embedded direct instruction, on the acquisition, generalization, and maintenance of phonological awareness, a key area of emergent literacy, by preschool children with language delays. Five male preschool participants with…

A common activity in school mathematics is to derive a function from a table of values. There are two general strategies one might adopt to determine the function f. First, one might try to determine a connection between a particular n and f(n), and then evaluate whether it holds for other values of n. An alternative strategy would be to look for…

This dissertation presents a formal theory of Serbo-Croatian grammar. The theory predicts acceptable form/meaning pairs for a substantial chunk of Serbo-Croatian. In particular, we analyze Serbo-Croatian declarative and interrogative main clauses, embedded clauses, a couple of different types of nominal modification, control and predication, as…

Research from the adaptive memory framework shows that thinking about words in terms of their survival value in an incidental learning task enhances their free recall relative to other semantic encoding strategies and intentional learning (Nairne, Pandeirada, & Thompson, 2008). We found similar results. When participants used incidental…

Objective: This study retrospectively examined the daily-level associations between youth alcohol use and dating abuse (DA) victimization and perpetration for a 6-month period. Method: Timeline Followback (TLFB) interview data were collected from 397 urban emergency department patients, ages 17 to 21 years. Patients were eligible if they reported…

In abstraction, or conceptual behavior, people discriminate features or properties of their surroundings. This permits people to respond selectively and precisely to specialized features of their environment, which has had many benefits, including steady advances in science and technology. Within psychology, J. R. Kantor and B. F. Skinner…

The MiGen project is designing and developing an intelligent exploratory environment to support 11-14-year-old students in their learning of algebraic generalization. Deployed within the classroom, the system also provides tools to assist teachers in monitoring students' activities and progress. This paper describes the design of these Teacher…

Experiments take place in a physical environment but also a social environment. Generalizability from experimental manipulations to more typical contexts may be limited by violations of ecological validity with respect to either the physical or the social environment. A replication and extension of a recent study (a blood glucose manipulation) was…

When subjects learn to associate two sample durations with two comparison keys, do they learn to associate the keys with the short and long samples (relational hypothesis), or with the specific sample durations (absolute hypothesis)? We exposed 16 pigeons to an ABA design in which phases A and B corresponded to tasks using samples of 1 s and 4 s,…

The literature pertaining to training staff, parents, and peers to implement interventions for individuals with developmental disabilities was reviewed for training procedures that incorporated strategies to promote generalization. The search engines for the "Journal of Applied Behavior Analysis" and Pubmed[C] were used to find relevant studies.…

Retrieval dynamics in context-dependent recall were explored via manipulations of external and internal context in two experiments. Participants were tested in either the same or different context as the material was learned in and correct recalls, errors, and recall latency measures were examined. In both experiments changes in context resulted…

Identifying alternative conceptions is a vital part of teaching and learning in science because it provides information about students' ideas to both themselves and their teachers. In this context, the purpose of the current study is twofold. The first aim is to examine high school students' alternative conceptions about general characteristics…

This study used a multiple-probe across participants design to examine the effects of the CD-Rom version of the "Self-Advocacy Strategy" on quality of contributions in Individual Education Plan (IEP) meetings of five high school students with intellectual disability. Results indicated a functional relationship between using the CD-Rom…

The authors examined effects of feedback and explanation on false belief performance. Thirty-three children (42-54 months; 15 girls, 18 boys) were randomly assigned to four treatment conditions: explanation, feedback, feedback researcher explains, and feedback child explains. Children completed false belief tasks during pretraining, 8 training…
