FUNCTIONAL ASSESSMENT OF BEHAVIORAL DISTURBANCES: DIAGNOSTIC FEATURES OF ASD BEHP1041 - Addresses functional assessment methodologies for severe behavior problems in persons with disabilities. Covers comparing outcomes of functional assessment experiments involving persons with and without ASD, studying where core diagnostic features of ASD were the focus of investigation, examining how core diagnostic features of ASD can interact with aspects of the environment to give rise to severe problem behavior, and other less-considered ways in which these interactions may occur.July 1, 2021 to June 30, 2022, Canvas 2
ADVANCED TOPICS IN FUNCTIONAL ANALYSIS - BEHP1043 Reviews functional analysis methodology presented integrated with recent critical research. Considers the assessment of low-frequency and high-risk behaviors in the area of difficult to assess behaviors. Details the impact of combined versus separate topographies. Also presents the roles of functional analysis in early intervention, across individual differences and specific to medication effects with additional research opportunities.July 1, 2021 to June 30, 2022, Canvas 2
ARRANGING REINFORCEMENT SYSTEMS IN APPLIED SETTINGS, PART 1 - BEHP1044 Reviews selection-based preference assessments, duration-based assessments and issues such as food/nonfood stimulus preferences. Includes reinforcer strength assessment with single and concurrent schedules and progressive ratio schedules. Presents studies that focus on shifts in preference and stimulus value change over time.July 1, 2021 to June 30, 2022, Canvas 2
ARRANGING REINFORCEMENT SYSTEMS IN APPLIED SETTINGS, PART 2 - BEHP1045 Presents a stimulating review of operations that may alter stimulus value. Includes the effects of exposure, value-changing effects and reinforcer and schedule dimensions. Reviews research on reinforcer variation and choice. Discusses motivating operation's influence on choices of food, activities and performance. Considers social reinforcers and a behavioral review of extrinsic and intrinsic motivation along with token reinforcer preference and response rates.July 1, 2021 to June 30, 2022, Canvas 2
REINFORCEMENT-BASED INTERVENTIONS FOR PROBLEM BEHAVIOR IN IDD - BEHP1092 Involves standard of care for severe behavior problems of persons with intellectual and developmental disabilities including conducting assessments to determine the variables that give rise to and support problem behavior and hypothesis-driven interventions that address these causes. Includes typical interventions such as disrupting the contingency between problem behavior and the consequences that support it (i.e., extinction), and establishing or strengthening alternative behavioral repertoires to displace problem behavior.July 1, 2021 to June 30, 2022, Canvas 2
