Recent advances in testing mediation have found that certain resampling methods and tests based on the mathematical distribution of 2 normal random variables substantially outperform the traditional "z" test. However, these studies have primarily focused only on models with a single mediator and 2 component paths. To address this limitation, a…

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…

By balancing the spacing effect against the effects of recency and frequency, this paper explains how practice may be scheduled to maximize learning and retention. In an experiment, an optimized condition using an algorithm determined with this method was compared with other conditions. The optimized condition showed significant benefits with…

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…

In this article we discuss the traditional behavioral models of depression and some of the challenges analyzing a phenomenon with such complex and varied features. We present the traditional model and suggest that it does not capture the complexity of the phenomenon, nor do syndromal models of depression that dominate the mainstream…

This paper provides an explanation for the nonspecificity of emotion inferences found in previous research [e.g., Language and Cognitive Processes, 19(5), 613-638, 2004]. We first demonstrate that behavioral components of emotions, as opposed to emotions per se, are better markers of readers' mental representations of the main character's…

Incorporating elements from broadband theories of psychological adaptation to extreme adversity, including Summit's (1983) Child Sexual Abuse Accommodation Syndrome, Finkelhor and Browne's (1986) Traumagenic Dynamics Model of sexual abuse, and Pyszczynski and colleagues' (1997) Terror Management Theory, this paper proposes a unified theoretical…

In school settings, behavior analysts are often called in to consult on severe behavioral issues that surpass the knowledge, experience, and training of local school personnel. Severe behavior such as aggression to staff, SIB, and property destruction are common severe behavior referrals. The benefits of functional assessments, functional…

The accountability movement in psychology has resulted in practitioners increasingly using evidence-based interventions and treatment modalities to treat client problems. Behavioral consultation is one framework that practitioners can utilize in providing empirically supported services. In order to demonstrate the use of effective, evidence-based…

Stimulation paradigms that induce perforant path long-term potentiation (LTP) initiate phosphorylation of ERK1/2 and induce expression of a variety of immediate early genes (IEGs). These events are thought to be critical components of the mechanism for establishing the changes in synaptic efficacy that endure for hours or longer. Here we show that…

The paper reviews research in early education, early intervention, applied behavior analysis and parent/child interaction to illustrate how methods and findings might suggest a model for ecobehavioral research in child development. An ongoing program of research is described to demonstrate application of the model. (Author/CL)

Paired associates and serial list memory are typically investigated separately. An "isolation principle" (J. B. Caplan, 2005) was proposed to explain behavior in both paradigms by using a single model, in which serial list and paired associates memory differ only in how isolated pairs of items are from interference from other studied items. In…

Dynamic factor models have been used to analyze continuous time series behavioral data. We extend 2 main dynamic factor model variations--the direct autoregressive factor score (DAFS) model and the white noise factor score (WNFS) model--to categorical DAFS and WNFS models in the framework of the underlying variable method and illustrate them with…

An international movement has focused on identifying evidence-based interventions that were developed to change psychological constructs and that are supported by controlled studies. However, inconsistent findings within individual intervention studies and among multiple studies raise critical problems in interpreting the evidence, and deciding…

Discusses behaviorism and the gradual shift to a theory of selectionism. Highlights include the development of behaviorism as a part of psychology, including Skinner's theories; varieties of behaviorism, including behavioral analysis; behaviorology in other disciplinary settings; effects of contingencies upon behavior; and the prospects for…
