Normed for ages 2:6 to 17:11 (Usual age range is 3:0 to 7:11; Out of level
age ranges are 2:6 to 2:11 and 8:0 to 17:11).
This subtest assesses short-term visual recognition in contrast to visual
recall on the Recall of Designs subtest. The child is shown a picture of one or
more objects for 5 to 10 seconds and then, when shown a page with the same as
well as other distracter pictures, is asked to recognize (by pointing) the
objects shown originally. The examiner does not name the objects. Success on
this task typically involves the ability to recognize and remember visual
images, some of which include discriminating among various details.
The subtest contains a total of 20 items, each scored as 1 or 0. Two starting
points are available (age 2:6 to 4:11 start at item 1 while 5:0 to 17:11 start
at item 5). Items 1 through 15 are exposed for 5 seconds, while items 16 to 20
have a 10-second exposure time.
Factor analytic findings
The Recognition of Pictures subtest is considered a fair measure of g for
ages 2:6 to 3:5 (r = .52) and a poor measure of g for all remaining subtests
(mean r = 45). Specificity is ample for all age groups 2:6 to 17:11.
Reliability and correlational highlights
Recognition of Pictures is considered to possess low overall reliability (r =
.72), with reliability coefficients ranging from .00 to .80 across all of the
age groups It has low correlations with all other subtests (mean r =.28)
in the battery.
In the Broad stratum definition of abilities, Recognition of Pictures is
considered to be a logical measure of both Visual Processing (Gv). In the Narrow
stratum of abilities, it is considered to be a probable measure of Visual Memory
(MV) (McGrew & Flanagan, 1998, p. 116).
Administrative and interpretive considerations
The Recognition of Pictures subtest is described on pages 251 to 254 in the DAS
Administration and Scoring Manual and discussed on page 69 in the DAS
Introductory and Technical Handbook Rather than trying to time each exposure
period by starting and stopping the stopwatch, simply keep the watch running and
gauge the 5 or 10 second interval with the running time.
For any item on which the child points to a single item but not all of the
target figures, examiners should ask the child if there are any more. This query
may be done only once per item.
Only the Preschool record form contains a scoring key for this subtest. The
key is presented in two ways: how the examiner sees the card and how the child
sees the card. Examiners should practice scoring this subtest several times to
get acquainted with this scoring key.
Children sometimes fail to anticipate the increasing difficulty of items and
miss one or two before they realize that they must study the pictures more
carefully. It is noteworthy if a child continues not to use the full exposure
time even after failing an item.
