The aim of this paper is to explore the conditions under which generalisation from single case studies, in the sense of making inferences concerning a wider class of phenomena beyond a case, is reasonable. Two sets of conditions, in particular, provide the basis for our consideration of this issue. The first is an exploration of the impressive…

The goal of the study is to analyze the morphological processing of real and novel verb forms by heritage speakers of Russian in order to determine whether it differs from that of native (L1) speakers and second language (L2) learners; if so, how it is different; and which factors may guide the acquisition process. The experiment involved three…

Constructing well-formed sentences is an important element of writing. However, many students struggle with this skill; in particular, writers with learning disability (LD). In this study sentence-combining practice with a peer-assistance component was used to improve the ability of four young students with LD to construct sentences and compose…

This investigation built upon previous studies that compared effectiveness and efficiency among instructional methods. Instructional effectiveness and efficiency were compared among three conditions: an incremental rehearsal, a more challenging ratio of known to unknown interspersal word procedure, and a traditional drill and practice flashcard…

Two groups of 10 male rats were trained to nose poke for food pellets at four alternatives that provided differing rates of pellet delivery on aperiodic schedules. After a fixed number of pellets had been delivered, 5, 10 or 20 in different conditions of the experiment, a 10-s blackout occurred, and the locations of the differing rates of pellet…

Conditions of children's political socialisation and education have more than ever in the last 40 years to deal with questions of social inclusion and exclusion. This is a result of social cleavages which are pertinent for children's lives and experiences. This article deals with this question while favouring an approach which shows that a…

This study determined the effectiveness of a commercially produced handheld computer, as a prompting system in facilitating the generalization and increasing the probability of long-term maintenance of vocational skills by adolescents with moderate intellectual disabilities. Four students successfully used the system in learning a task and then…

Following a 1986 study reporting a predominance of ambivalent attachment among insecure Sapporo infants, the generalizability of attachment theory and methodologies to Japanese samples has been questioned. In this 2nd study of Sapporo mother-child dyads (N = 43), the authors examined attachment distributions for both (a) child, based on M. Main…

This study compared the effects of circumscribed interests (CI) to less preferred (LP) tangible stimuli on the social behaviors of three children with autism spectrum disorders (ASD). Based on single subject design methodology, the CI experimental sessions resulted in longer durations of target-child initiated social interactions in comparison to…

Experimental research involves comparing two or more conditions. One of those conditions in single subject research is often the baseline. Adequate description of the baseline conditions is necessary for evaluating the effects of independent variables, drawing generalizations from studies, and providing information for subsequent replication…

Sometimes it is important to look back so that one can more clearly determine future directions. As such, the purpose of this paper was twofold. First, characteristics of participants, settings, interventions, interventionists, design, and measures were coded and analyzed to ascertain the nature of publication trends in the "Journal of Behavioral…

This article proposes a developmental model to socialize teachers at all levels (preservice, novice, and experienced) and in all positions (general education, special education, elementary school, middle school, and high school) in the methodology of action research. A process for advancing professional understanding is theorized to include the…

Two studies examined the impact of temporal synchrony on infants' learning of and memory for sight-sound pairs. Findings indicated that 7-month-olds had no difficulty learning auditory-visual pairs regardless of temporal synchrony, remembering them 10 minutes later and 1 week later. Three-month-olds showed poorer learning in no-synchrony than in…

Twenty-one 4th- and 5th-grade students with learning disabilities and emotional disabilities were assigned at random to a control condition or to an experimental condition in which they were taught, over a 9-week period, a five-step self-determination strategy for solving school- or home-related problems. Maintenance was assessed 3 weeks after the…

Childhood obesity has become a problem of epidemic proportions in the United States, but much of the research has focused on prevention and intervention programs, which target the general population of school children. Overlooked in the literature are children with special needs (including autism, genetic disorders, Down syndrome, and Prader-Willi…
