CALCAP® Abbreviated
Test Battery (Test
Duration: 8-10 minutes)
Return to main menu
The Abbreviated version of the CalCAP provides a very brief screening
battery using only those measures from the Standard test
battery that are most sensitive to cognitive decline. The Abbreviated
battery is ideally suited for collecting reliable information on psychomotor
functioning in a brief period of time, and can be used effectively for
assessing changes over time. The task entitled Serial Pattern Matching 2 is new
and is designed to be even more sensitive to subtle cognitive deficits than
Serial Pattern Matching 1.
- Simple Reaction Time. Subjects are asked to press a key as soon as they see
anything at all on the screen. This procedure provides a basal measure of
reaction time.
- Choice Reaction Time for Single Digits. Subjects are asked to
press a key as soon as they see a specific number such as '7', otherwise
they are to do nothing. This procedure adds a simple element of memory to
the task.
- Serial Pattern Matching 1 (Sequential Reaction Time 1). Subjects are asked to
press a key only when they see two of the same number in sequence, for
example, if they see the number '3' followed by a second occurrence of the
number '3'. This procedure adds a more complex element of memory since the
subject must keep in mind the last number that was seen.
- Serial Pattern Matching 2 (Sequential Reaction Time 2). Subjects are asked to
press a key only when they see two numbers in sequence (increasing order).
For example, if they see the number '3' followed by the number '4', the
number '6' followed by '7' and so on.
Normative data are available from over 600 subjects
ranging in age from 23 to 72. A variety of psychometric
properties have been established, including internal consistency
reliability, test-retest reliability, and indices of validity.
