Cognitive Assessment System - Present Use

Present Use

CAS is used for understanding cognitive development of typical and atypical children, as well as cognitive impairment in adults. It has been used for research, diagnosis, and clinical evaluation by several professionals including educational and school psychologists because it provides good guidelines for educational interventions.

Research on the relationship between the CAS and achievement has shown that the PASS processes strongly predict academic achievement in spite of the fact that it does not include vocabulary (Naglieri and Rojahn, 2004). Similarly, CAS tests have been used for understanding, assessment of and intervention with educational problems associated with reading disabilities (Das, 2009 ) such as autism, attention-deficit-hyperactivity disorder (Naglieri, 2005). CAS tests have also been used for clinical evaluation of mental retardation and cognitive changes in ageing (Das, 2003).

Deserving of special mention is the use of CAS tests for fair assessment of minorities (Naglieri, 2005) and First Nation children whose chronic weakness in reading has been identified as a successive processing deficit compounded by poor home literacy (Das, Janzen & Georgiou, 2007) both of which can be improved through PASS-related intervention (Hayward, Das & Janzen, 2007).

Additionally, CAS with supplementary tests has been found useful for research related to executive decision making in management (Das, Kar, & Parrila,1996).

CAS withstands adaptation and translation into other languages. CAS in Dutch, Italian, Japanese, Korean, Spanish (Castillian), Norwegian and Swedish are commercially available. In addition, CAS has been used in Chinese, Greek, Norwegian and Dutch research.

Famous quotes containing the word present:

    “If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years.”
    —Josiah Royce (1855–1916)

    “In any weather, at any hour of the day or night, I have been anxious to improve the nick of time, and notch it on my stick too; to stand on the meeting of two eternities, the past and the future, which is precisely the present moment; to toe that line.”
    —Henry David Thoreau (1817–1862)
