Getting to the Point: Examining Associations Between Adult Interactional Strategies and Infant Gestures.

The developmental importance of infant gesture use is well established, yet few investigations examine what adults can do to facilitate infant gestures. We used an event lag with pauses sequential analysis to generate an index of association between each adult interactional strategy and deictic infant gesture during ten-minute play interactions with 27 typically developing infants (11-25 months) and trained interventionists. We ran correlations to examine potential relationships between the sequential associations, child age, and language scores.

Are Function-Based Interventions for Students with Emotional/Behavioral Disorders Trauma Informed? A Systematic Review.

Students with emotional/behavioral disorders (EBD) commonly engage in both externalizing and internalizing behaviors-a behavioral profile that has been connected to childhood trauma. Although the efficacy of function-based interventions for students with EBD has been documented, the extent to which these interventions align with principles of trauma-informed care (TIC) is unknown. We conducted a systematic review of function-based intervention studies for students with EBD to evaluate whether and how these interventions incorporated critical elements of TIC.

A Systematic Review of Direct Assessments to Evaluate Psychotropic Medication Effects for Children With Disabilities.

To evaluate effects of psychotropic medication for children with disabilities, direct assessments may offer a valuable supplement to caregiver reports. Relative to indirect assessment, direct measures of behavior can increase objectivity and sensitivity, and some have potential to isolate distinct behavioral and learning processes. We conducted a systematic, narrative literature review to identify and describe the types and qualities of direct assessment methods that have been used to evaluate effects of non-stimulant psychotropic medication for children with disabilities.

Direct Measures of Medication Effects: Exploring the Scientific Utility of Behavior-Analytic Assessments.

The purpose of the current study was to explore the scientific utility of two behavior analytic assessments (i.e., progressive ratio and demand assessments) for psychotropic medication evaluation.

Effects of self-control training for elementary students with emotional and behavioral disorders.

Progressive delay training (PDT) has been used to promote self-controlled choices (i.e., selecting a larger, later reward over a smaller, immediate reward) for people with a variety of developmental characteristics.

Effects of School-Home Communication With Parent-Implemented Reinforcement on Off-Task Behavior for Students With ASD.

School-home communication is highly valued for parents of students with autism spectrum disorders (ASD) and other developmental disabilities. However, parents report poor communication as a common barrier to developing partnerships with schools. Using a multiple baseline design, we evaluated the effects of a school-home note intervention with parent-implemented reinforcement for decreasing off-task behavior of students with ASD at school.

Randomization Tests for Single Case Designs with Rapidly Alternating Conditions: An Analysis of -Values from Published Experiments.

Two common barriers to applying statistical tests to single-case experiments are that single-case data often violate the assumptions of parametric tests and that random assignment is inconsistent with the logic of single-case design. However, in the case of randomization tests applied to single-case experiments with rapidly alternating conditions, neither the statistical assumptions nor the logic of the designs are violated. To examine the utility of randomization tests for single-case data, we collected a sample of published articles including alternating treatments or multielement designs with random or semi-random condition sequences.

A comparison of analysis methods to estimate contingency strength.

To date, several data analysis methods have been used to estimate contingency strength, yet few studies have compared these methods directly. To compare the relative precision and sensitivity of four analysis methods (i.e.

Single-case synthesis tools II: Comparing quantitative outcome measures.

Varying methods for evaluating the outcomes of single case research designs (SCD) are currently used in reviews and meta-analyses of interventions. Quantitative effect size measures are often presented alongside visual analysis conclusions. Six measures across two classes-overlap measures (percentage non-overlapping data, improvement rate difference, and Tau) and parametric within-case effect sizes (standardized mean difference and log response ratio [increasing and decreasing])-were compared to determine if choice of synthesis method within and across classes impacts conclusions regarding effectiveness.

Single-case synthesis tools I: Comparing tools to evaluate SCD quality and rigor.

Tools for evaluating the quality and rigor of single case research designs (SCD) are often used when conducting SCD syntheses. Preferred components include evaluations of design features related to the internal validity of SCD to obtain quality and/or rigor ratings. Three tools for evaluating the quality and rigor of SCD (Council for Exceptional Children, What Works Clearinghouse, and Single-Case Analysis and Design Framework) were compared to determine if conclusions regarding the effectiveness of antecedent sensory-based interventions for young children changed based on choice of quality evaluation tool.

Sequential Associations Between Caregiver Talk and Child Play in Autism Spectrum Disorder and Typical Development.

This study examined sequential associations between child play and caregiver talk in 98 caregiver-child dyads (M  = 14 months). Fifty dyads included a child with autism spectrum disorder (ASD). Analyses revealed sequential associations between child play and caregiver follow-in (FI) utterances (utterances related to the child's attentional focus) were stronger in the ASD as compared to the typically developing (TD) group.

Experimental analysis of stereotypy with applications of nonparametric statistical tests for alternating treatments designs.

Introduction: Stereotypy is common in individuals with developmental disabilities and may become disruptive in the context of instruction.

Purpose: The purpose of this study was to embed brief experimental analyses in the context of reading instruction to evaluate effects of antecedent and consequent variables on latencies to and durations of stereotypy.

Method: We trained a reading instructor to implement a trial-based functional analysis and a subsequent antecedent analysis of stimulus features for an adolescent with autism in a reading clinic.

The relative accuracy and interpretability of five sequential analysis methods: A simulation study.

A variety of sequential analysis methods exist to quantify close temporal associations between events from direct observation data. In the present study, we compared the relative accuracy and interpretability of five sequential-analysis methods using simulated data. The methods included three existing approaches (event lag, concurrent interval, and time window) and two proposed modifications of the event lag approach (event lag with contiguous pauses and event lag with noncontiguous pauses) designed to address limitations of the existing approaches.

Assessment and treatment of challenging behaviour for individuals with intellectual disability: a research review.

Background: Challenging behaviour is frequently associated with the presence of intellectual disability. If not effectively treated, chronic challenging behaviour can negatively impact a variety of quality of life outcomes for individuals with intellectual disability.

Methods And Results: We review the current status of research relating to the assessment and treatment of challenging behaviour for people with intellectual disability.

Quantifying contingent relations from direct observation data: transitional probability comparisons versus Yule's Q.

Measuring contingencies or sequential associations may be applied to a broad range of response-stimulus, stimulus-stimulus, or response-response relations. Within behavior analysis, response-stimulus contingencies have been quantified by comparing 2 transitional probabilities and plotting them in contingency space. Within and outside behavior analysis, Yule's Q has become a recommended statistic used to quantify sequential associations between 2 events.

Serotonin₂A/C receptors mediate the aggressive phenotype of TLX gene knockout mice.

Deleting the tailless (TLX) gene in mice produces a highly aggressive phenotype yet to be characterized in terms of heterozygous animals or neurotransmitter mechanisms. We sought to establish pharmacological control over aggression and study the role of serotonin (5-HT)(2A/C) receptors in mediating changes in aggression. We analyzed aggression in mice heterozygous (+/-) or homozygous (-/-) for the TLX gene and wild-types (+/+) using a resident-intruder paradigm.
