The TEC is a standardized, computer-administered measure of two fundamental aspects of executive control processes: working memory and inhibitory control. Easily-identifiable visual stimuli are presented in six different task conditions, with stepwise increases in working memory load, in “inhibitory demand” and “no inhibitory demand” conditions. It produces Factor Scores, Summary Score and Task Scores.

Evaluates a wide variety of developmental and acquired neurological disorders:
*Attention Disorders                                       *Learning Disabilities
*Autism Spectrum Disorders                           *Traumatic Brain Injuries
*Psychiatric and Behavioral Concerns

The TEC represents the first standardized, clinical application of two integrated neuroscience methods commonly used to tap working memory and inhibitory control: an n-back paradigm that parametrically increases working memory load, and a go/no go task to manipulate inhibitory control demand. This combination of methods yields for sequential tasks for 5- to7-year-old children, and six tasks for older children and adolescents (8-18 years). 

Three equivalent forms and two research forms are included, along with standardized regression-based change scores that facilitate interpretation of:
*Change between performance tasks
*Change over time

With highly-accurate timing, and a stable platform, the TEC calculates multiple norm-referenced measures of accuracy, response time, and response time variability as working memory load increases in both “inhibit” and “no inhibit” conditions.

The program monitors accuracy and response time throughout administration to produce six accuracy scores, and two response-time variability scores for each task. Each task consists of on-screen instructions, a set of practice trials with feedback, and 100 timed-interval stimuli that require responses. The software provides a Score Report, which displays scores and profiles from a single administration; a Protocol Summary Report, which summarizes changes over time; and a comprehensive Client Report, which provides interpretive statements for a single administration.

A post-stratification weighting procedure was applied to the TEC standardization sample of 1,107 individuals to most accurately reflect population parameters as defined by the U. S. Census (2007). Form 1 reliability coefficients based on the Spearman-Brown split-half formula ranged from .75 to .98 for Factor scores and from .68 to .99 for Summary scores.

Convergent evidence for validity of the TEC is based on correlations with the BRIEF (Stoelting Cat. No. 32731), the CPRS-R:L, and the CBCL/6-18, among others. Its validity was also investigated within several clinical samples, including children and adolescents with ADHD, mild traumatic brain injury, learning disabilities and Fragile X Syndrome.
