Multiple uses of the same assessment may present challenges for both the design and use of an assessment. Little advice, however, has been given to assessment developers as to how to understand the phenomena of multiple assessment use and meet the challenges these present. Particularly problematic is the case in which an assessment is used for…

This study examined the effects yielded from the implementation of assessment-based behavior support plans on the engagement and problem behavior of three young children with behavioral challenges in a community early childhood program. A concurrent multiple-baseline design across children with generalization probes was used with data collected…

Purpose: Investigators taught a 5-year-old boy with autistic disorder and severe language delay to conditionally use requests for assistance. Method: A within-participant multiple-probe design across 3 functional tasks was implemented in order to evaluate the child's acquisition and conditional use of requests for assistance during intervention…

Phonological and semantic principles which underlie the derivation of verbs from nouns and adjectives in English are examined. There is intricate phonological conditioning for suffix "-ize" and for suffix "-(i)fy"; a third major process is zero derivation. These derivational processes cover more than a score of semantic relations (some with…

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to…

The bookmark standard-setting procedure is an item response theory-based method that is widely implemented in state testing programs. This study estimates standard errors for cut scores resulting from bookmark standard settings under a generalizability theory model and investigates the effects of different universes of generalization and error…

This paper argues that the new science of positive psychology is founded on a whole series of fallacious arguments; these involve circular reasoning, tautology, failure to clearly define or properly apply terms, the identification of causal relations where none exist, and unjustified generalisation. Instead of demonstrating that positive attitudes…

Development in any domain is often characterized by increasingly abstract representations. Recent evidence in the domain of shape recognition provides one example; between 18 and 24 months children appear to build increasingly abstract representations of object shape [Smith, L. B. (2003). Learning to recognize objects. "Psychological…

Determining whether a sample provides a good basis for broader generalizations is a basic challenge of inductive reasoning. Adults apply a diversity-based strategy to this challenge, expecting diverse samples to be a better basis for generalization than homogeneous samples. For example, adults expect that a property shared by two diverse mammals…

This study describes the reliability reporting practices in empirical studies using eight adolescent alcohol screening tools and characterizes and explores variability in internal consistency estimates across samples. Of 119 observed administrations of these instruments, 40 (34%) reported usable reliability information. The Personal Experience…

This series of three studies considers the multidimensionality of exercise self-efficacy by examining the psychometric characteristics of an instrument designed to assess three behavioral subdomains: task, scheduling, and coping. In Study 1, exploratory factor analysis revealed the expected factor structure in a sample of 395 students.…

The purpose of the present study was to investigate the acquisition, maintenance, and generalization effects of antecedent prompt and testing procedure (APTP) on teaching emergency phone numbers to youth with developmental disabilities. Three youths with mental retardation participated in the study. All participants were inclusion students at a…

The purpose of this study was to examine the dimensionality of the "Contact With Disabled Persons Scale" (CDP). An exploratory factor analysis of the CDP yielded three factors: General Interpersonal Contacts, Positive Contact Experiences, and Negative Contact Experiences. A confirmatory factor analysis provided further evidence for the stability…

This study investigated the effectiveness of a brief staff training procedure aimed at promoting the generalization of accurate implementation of discrete trial instruction from the training environment to the teaching environment. Three bachelor's-level paraprofessionals received classroom training using a training package that included didactic…

When causal inferences are to be synthesized across multiple studies, efforts to establish the magnitude of a causal effect should be balanced by an effort to evaluate the generalizability of the effect. The evaluation of generalizability depends on two factors that are given little attention in current syntheses: construct validity and external…
