Executive Functioning An Introduction

Definition Executive Functioning as a defined term is a relatively recent development (a caution!) A fluid definition! Previously assessed primarily by neuropsychologists Most recently it has moved to the domain of psychoeducational assessment as its contributions towards academic difficulty and the benefits of disorder specific remediation have become better known.

Executive Functioning as a defined term is a relatively recent development (a caution!)

A fluid definition!

Previously assessed primarily by neuropsychologists

Most recently it has moved to the domain of psychoeducational assessment as its contributions towards academic difficulty and the benefits of disorder specific remediation have become better known.

A Working Definition Executive Functions are higher order cognitive skills associated with the ability to engage in independent, goal-directed behavior. Draw on fundamental skills to generate higher levels of creative & abstract thought May result in obvious behavior disorder or subtle problems with behavioral regulation Also known as dysexecutive syndrome

Executive Functions are higher order cognitive skills associated with the ability to engage in independent, goal-directed behavior.

Draw on fundamental skills to generate higher levels of creative & abstract thought

May result in obvious behavior disorder or subtle problems with behavioral regulation

Also known as dysexecutive syndrome

A Working Definition Due to the wide ranging complexity of executive functioning it is difficult to produce an accurate single statement to describe the construct or the disorder. As a result it is frequently described by the nature of the dysfunction and the general symptom pattern Impairments in executive functioning have been linked to dysfunction of the frontal lobes

Due to the wide ranging complexity of executive functioning it is difficult to produce an accurate single statement to describe the construct or the disorder.

As a result it is frequently described by the nature of the dysfunction and the general symptom pattern

Impairments in executive functioning have been linked to dysfunction of the frontal lobes

Defining Executive Functions There is certainly a debate regarding how we should exactly define executive functioning or executive functioning impairments Fortunately the assessment of these domains seems to have transcended the bantering of theorists Examining their work, however, does help us better understand what exactly is going on here

There is certainly a debate regarding how we should exactly define executive functioning or executive functioning impairments

Fortunately the assessment of these domains seems to have transcended the bantering of theorists

Examining their work, however, does help us better understand what exactly is going on here

Defining Executive Functions Martha Denkla warns us that we should avoid turning executive functions into the neuropsychologist’s “g” Yet other theorists have jumped on this idea (Elkhonon Goldberg refers to executive functions as the “S”(for smart) Factor). Paradoxically, both Denkla and Goldberg use the analogy of the Orchestra Conductor as a metaphor and support structure for executive processes at work.

Paradoxically, both Denkla and Goldberg use the analogy of the Orchestra Conductor as a metaphor and support structure for executive processes at work.

EF as Conductor of the Brain’s Orchestra The simple orchestra conductor analogy feeds into the ‘g’ style or “S” model approach of Goldberg However, this is likely a real underestimation of the complexity of executive functions and falsely suggests we can look for a single score to represent executive capabilities For practical everyday problem-solving in a more concrete manner, it is better to stick with a concept of a system of interrelated “semi-conductors” rather than posit a single conductor. EF =Cognitive Ability

That’s a lot of problems! “ Deficits in PFC [prefrontal cortex, aka frontal lobes] function are evident in every neuropsychiatric disorder (indeed, the term “psychiatric problem” seems synonymous with PFC dysfunction).” Arnsten & Robbins 2002 in Principles of Frontal Lobe Function Most of the clinical conditions described in the DSM-IV reflect some form of Executive Dysfunction The DSM-IV can be thought of as “A User’s Guide to All the Things That Can Go Wrong With the Frontal Lobes” The frontal lobes differentiate us from all other species. They are also what messes us up!

Executive Functioning Relationship with School and Core Assessment

EF & Intelligence Broad theoretical definitions of EF differ in the level in which they implicitly or explicitly include or exclude executive control processes as part of “Intelligence” Narrow theoretical definitions often include executive functions implicitly as part of problem-solving or reasoning in “Intelligence” “ The ability to carry on abstract thinking.” (L.M. Terman) Intelligence is the capacity to learn from experience, using metacognitive processes to enhance learning, and the ability to adapt to the surrounding environment, which may require different adaptations within different social and cultural contexts.” (Sternberg, 2003)

EF & Intelligence The operational definitions of intelligence used to guide test development typically do not include executive functions as a distinct component to be assessed. Many measures of intelligence involve executive control to some degree, but the role and effect of EFs are often minimized by the assessment procedures. Subtest Directions: Do this .. Then this .. Then this .. Then this It is often necessary to include specific measures of executive control in an assessment in order to characterize the role of EFs in “intelligent” behavior. EF involvement can be understood through the application of a process approach while administering tasks developed to assess various cognitive abilities.

EF involvement can be understood through the application of a process approach while administering tasks developed to assess various cognitive abilities.

EF & Working Memory It has been vigorously debated whether these two processes are one in the same Correlation studies between various EF subtests on the Delis-Kaplan Executive Function System (DKEFS) and the WMI index and Subtests from WISC-IV and WISC-IV Integrated have showed that while there is certainly a relationship between these abilities they are not a synonymous function Working memory processes involved in manipulating information in mind are dissociable from the executive processes that direct or cue the use of working memory resources .

Working memory processes involved in manipulating information in mind are dissociable from the executive processes that direct or cue the use of working memory resources .

EF in the Classroom Although executive functions are used to guide cognitive processing involved in new learning, many new learning situations are structured in ways that reduce the need for strong executive direction. In contrast, demonstrating what has been learned usually requires significant involvement of executive control processes. Because internally driven production is much easier to accomplish than externally demanded production for children with “producing difficulties” their lack of production on demand often stands in stark contrast to their seemingly effortless production “when the spirit moves them.” The on-demand deficiencies are often attributed to negative qualities such as lack of responsibility, apathy, passive aggressive stance, or oppositional defiance.

Executive Functioning Psychoeducational Assessment

Cautions! There are several great measures of executive functioning available but there are several very important cautions that we must consider (and are frequently ignored!)

executive functioning available but there are

several very important cautions that we must

consider (and are frequently ignored!)

Cautions No single subtest/score can represent executive functioning Use of a behavioural checklists alone will typically overestimate executive impairments in the general school population. There is a lot of reasons kids act out! We must consider that there are significant age effects in EF. We must think of many of these traits as developmental milestones. At the earliest ages (8-10) we may want to consider retesting or monitoring of EF down the road

Any executive functioning assessment should include a behavioural based questionnaire like the BRIEF, Brown ADD or DEX

These allow for environmental and ecologically reliable information to be introduced into the assessment in a standardized way

These measures also provide good screeners for impairment in these areas

The Brown ADD looks predominately at ADD based EF symptom patterns The BRIEF was designed to look at general EF but its hard to tell how well it is doing that since the vast majority of studies in the manual are ADD based. The BRIEF is by far the most frequently used EF measure in schools but be cautious. It vastly overestimates impairment (review the sensitivity/specificity studies) at T=60 and loses a lot of sensitivity of T=70. I tend to utilize the teacher form most frequently (most stable reliability/validity) Behavioural Questionnaires
