In this article, we directly question the common practice in growth mixture model (GMM) applications that exclusively rely on the fitting model without covariates for GMM class enumeration. We provide theoretical and simulation evidence to demonstrate that exclusion of covariates from GMM class enumeration could be problematic in many cases. Based…

Amid the novel terms and original analyses in Skinner's "Verbal Behavior", the importance of his discussion of multiple control is easily missed, but multiple control of verbal responses is the rule rather than the exception. In this paper we summarize and illustrate Skinner's analysis of multiple control and introduce the terms "convergent…

If the members of a functional response class occur in a predictable order, a response-class hierarchy is said to exist. Although this topic has received some attention in the applied literature, it remains relatively understudied. The purpose of the current investigation was to develop an analogue model of a response-class hierarchy. Children…

This article describes a Response to Intervention (RTI) model of service delivery implemented within a rural elementary school for students in kindergarten through fifth grade experiencing significant emotional and behavioral difficulties. A multi-tiered model is presented that includes school wide interventions in Tier 1, as well as a six…

Poverty remains an urgent crisis worldwide. In the United States, 28.6 million children live in low-income families and 12.7 million children live in poor families. In nations belonging to the Organization for Economic Co-operation and Development (OECD), 47 million children live below national poverty lines. These figures pertain to…

Some children with autism demonstrate poor nonword repetition--a deficit considered to be a psycholinguistic marker of specific language impairment (SLI). The present study examined whether there is an SLI subtype among children with autism. We compared the language abilities of children with SLI (n = 34, M age = 11;10 S.D. = 2;3), and children…

Studies the effect of eight prearranged situations on the prosocial, problem, and task-related behavior of three hyperactive boys. Behaviors assessed included adult, peer, and target-child attention given and received; compliance; aggression; disruption; task involvement; and percentage of tasks correctly completed. (Author/CI)

Amphetamines and other stimulant drugs are not causing so-called "paradoxical effects" in hyperactive children but are actually effective because they provide needed stimulation. According to the Swanson-Brodemus Model, amphetamines, et al., provide internal sources of stimulation, thus reducing the need for external stimulation. (Author)

Applies a suicide trajectory model to rates of suicide and attempted suicide to explain commonalities and age differences in risk factors affecting suicide across the life span. (HTH)

A model for the analysis of simple human conceptual behavior, based on the apparent similarities of human conceptual behavior and that of infrahuman subjects, is developed. A minimum definition of conceptual behavior is given: A single response, verbal or nonverbal, under the discriminative control of a group of stimuli whose parameters are…

This paper reviews a number of studies that have tested Fiedler's (1964) Contingency Model and Least Preferred Co-Worker Scale of leadership style and effectiveness, focusing on studies that have examined the characteristics and stability of this scale across age, ethnicity, and gender. The Contingency Model is based on three determinants of…

Proposes the dialectical perspective as offering fertile ground for the integration of child and family research and training. Defines the dialectical perspective and then discusses its applicability in a department of child and family studies. (Author)

A model of social skills in childhood and adolescence using the concepts and literature on symbolic interactionism is proposed. Its components (role-taking, role-making, definition of situation, and self) and their potential contributions to social skills analysis are discussed. An application to friendship making and possible model limitations…

To synthesize knowledge concerning factors which affect occupational achievement through a set of explicit models based upon the concept of the socioeconomic life cycle, six major bodies of data from various sources were collected and subjected to secondary analysis. A number of items of lesser scope were gleaned from additional sources for use in…
