“…From all this, it follows that, at best, the CET can identify the (maybe clinically relevant) tendency to give more or less untypical estimations, whereby the reasons for such deviations are unknown. Given the concerns about the internal consistencies of cognitive estimation tests, the items of these tests may even measure different constructs (Scarpina et al, 2015). Vohs et al (2021) did not report the internal consistency of the CET in their study, which is typically rather low [e.g., Cronbach's α = 0.60 in Schultz and Ryan (2019)].…”

“…The original CET comprised of 15 questions and has long since been used to assess estimation abilities in both clinical and research settings. Several different versions of the CET have been developed (e.g., Brand et al, 2003 ; Bullard et al, 2004 ) and studies have reported normative data for these different CET versions (e.g., Axelrod and Millis, 1994 ; Della Sala et al, 2003 ; Scarpina et al, 2015 , for a review of the different CET versions see Wagner et al, 2011 ). We have recently developed two new 9-item parallel versions of the CET (i.e., CET-A and CET-B) with the aim of providing more up-to-date items that can be administered in different countries, on more than one occasion ( MacPherson et al, 2014 ).…”

Cognitive estimation: Performance of patients with focal frontal and posterior lesions

The Cognitive Estimation Test (CET) is a widely used test to investigate estimation abilities requiring complex processes such as reasoning, the development and application of appropriate strategies, response plausibility checking as well as general knowledge and numeracy (e.g., Shallice and Evans, 1978; MacPherson et al., 2014). Thus far, it remains unknown whether the CET is both sensitive and specific to frontal lobe dysfunction. Neuroimaging techniques may not represent a useful methodology for answering this question since the complex processes involved are likely to be associated with a large network of brain regions, some of which are not functionally necessary to successfully carry out the CET. Instead, neuropsychological studies may represent a more promising investigation tool for identifying the brain areas necessary for CET performance. We recently developed two new versions of the CET (CET-A and CET-B; MacPherson et al., 2014). We investigated the overall performance and conducted an error analysis on CET-A in patients with focal, unilateral, frontal (n = 38) or posterior (n = 22) lesions and healthy controls (n = 39). We found that frontal patients’ performance was impaired compared to healthy controls on CET. We also found that frontal patients generated significantly poorer estimates than posterior patients on CET-A. This could not be explained by impairments in fluid intelligence. The error analyses suggested that for CET-A, extreme and very extreme responses are impaired following frontal lobe damage. However, only very extreme responses are significantly more impaired following frontal lobe than posterior damage and so represent a measure restricted to frontal “executive” impairment, in addition to overall CET performance.

“…This finding that age affects performance on some fronto-executive tests (i.e., inhibition, switching, and updating measures) but not others (i.e., dual-tasking) speaks against the frontal lobe hypothesis of aging, which would predict that performance on all executive tests is vulnerable to healthy aging (Dempster, 1992;Moscovitch & Winocur, 1992;West, 1996West, , 2000. This is not novel as other cognitive aging studies have reported certain executive tests do not consistently show age-related differences (see MacPherson & Della Sala, 2015) such as the CET (Axelrod & Millis, 1994;Della Sala et al, 2003;Gillespie et al, 2002;MacPherson et al, 2014;Scarpina et al, 2015), letter fluency (Henry & Phillips, 2006;Lamar & Resnick, 2004;Parkin et al, 1995), as well as dualtasking (Baddeley et al, 1991;Della Sala et al, 2010;Foley et al, 2011;MacPherson et al, 2007). Together these findings suggest that the frontal lobe hypothesis may be an oversimplification in terms of age effects on executive tests and the underlying causes for these differences should be explored further.…”

Although studies report age-related declines on tests of executive function, not all executive tests show age differences, including the dual-task paradigm. As processing speed is known to decline with age, it is possible that changes in speed contribute to the variation in agerelated decline found on different tests of executive function. In this study, the effects of age and processing speed on different executive tests in the same group of younger and older adults were investigated. Fifty-nine (n = 28 males & n = 31 females) younger adults (Mage = 21.49; SD = 2.54) and N = 52 (n = 22 males & n = 30 females) older adults (Mage = 72.04; SD = 4.99) were assessed on the following battery of measures: processing speed and the executive functions of dual-tasking, inhibition, set-shifting, and updating. Older adults performed significantly worse than younger adults on all executive function tests except dual-tasking. In addition, age, rather than processing speed, predicted executive function performance on executive tests of inhibition, set-shifting and updating tests. These findings confirm that dual-tasking does not decline with age and the age differences found on tests of inhibition, set-shifting and updating are not simply explained by processing speed.
