Advanced Cross-Battery AssessmentUsing CHC Theory and Neuropsychological Measures Catherine A. Fiorello, Ph.D., ABPP Temple University September 30, 2011
Workshop Objectives • Participants will be able to: • Use XBA to detect processing deficits in identifying students with LD and ADHD • Describe how processing assessment can be integrated within an RtI model • Understand how CHC Theory and neuropsychological assessment work together
Cognitive Product or Process:Synthesizing Paradigms Nomothetic Assessment Idiographic Assessment • Compares individual to norm • Focuses on score: Assessment Product • Interpret levels of performance • Compares individual to self • Focuses on performance: Assessment Process • Interpret patterns of performance BOTH essential for effective assessment and intervention

Identifying Children with Learning Disabilities: IDEA Definitions and Practices Defining Learning Disabilities • Learning Disabilities is a disorder of one or more of the basic psychological processes that adversely affects educational achievement in one or more academic domains Determining Learning Disabilities • Discrepancy between “ability” and “achievement” (typically using cut-off points and global IQ) • Failure to respond to scientific research-based intervention • May permit the use of other alternative research-based procedures for determining whether a child has a specific learning disability, as defined in §300.8(c)(10) (OSERS Final Regulations-8/06)
RtI as Prereferral Process • Prereferral interventions, with good progress monitoring, are essential to serving children. • Interventions may help a large number of children (e.g., Torgeson, early reading, 94-96%). • Tracking response to intervention provides good information about what works and what doesn't. • Avoids “waiting to fail.”
Problems with RtI • Established interventions for many referral problems do not exist. • Agreement on goal setting (what is failure to respond?) can be problematic. • Many children are referred for multiple areas of difficulty. • Failure to respond may be due to many reasons other than disability.
RtI and LD • RtI provides valuable information as part of an evaluation for learning disabilities • A failure to respond to interventions is not, by itself, diagnostic of a learning disability. • Cognitive and neuropsychological processing is critical to identifying LD. • School psychologists can and should evaluate processing.

Processing and LD • Literature in cognition, cognitive assessment, neuropsychology, and learning disabilities links cognitive processing with achievement and LD. • Regular education curricula tend to focus on a few areas of processing (e.g., phonemic awareness) to the exclusion of many others. • Once there has been failure to respond, process assessment can be used to develop interventions.

Developing and Testing Hypotheses About Cognitive Processes and Achievement • Examine profile for significant subtest or factor scatter • If global scores are invalid, interpret subtest performance within and between subtests • Use Demands Analysis to examine Input, Processing, and Output Demands • (Caution: Processing Demands More Relevant) • Demands Analysis is prone to error, must validate with additional measures • (Caution: Avoid Cookbook Interpretation) • Data must show convergent, divergent, AND ecological validity
Demands Analysis: Block DesignDetermining InputProcessingOutput Demands
Demands Analysis: WISC-IV Block DesignDetermining InputProcessingOutput Demands • Input Demands: • Models and abstract visual pictures • Lengthy oral directions-receptive language • Demonstration and modeling • Perception of timed task • Low cultural knowledge and emotional content
Demands Analysis: WISC-IV Block DesignDetermining InputProcessingOutput Demands • Processing Demands: • Novel task for most children (note beginning vs. later task performance-also when lines removed) • Visual processing: Spatial-global • Visual processing: Directional orientation-local • Perceptual analysis (divergent thought) and synthesis (convergent thought) • Planning, strategizing, and monitoring performance: Match to sample • Sustain attention, inhibit impulsive/error responding
Demands Analysis: WISC-IV Block DesignDetermining InputProcessingOutput Demands • Output Demands: • Fine motor response, arrange manipulatives • Bimanual sensory (visual-somatosensory) – motor coordination • Processing speed
