Problem solving: bad bugs; insensitivity to the “obvious” (3/30/79) |
One of those many times she has sat in my lap, Peggy began trying to
uncap pens. (She has seen me put the cap on firmly many times, so
that when she put them in my pockets or took them out she would not
get ink all over). she succeeded with various bic pens and today she
tackled a black (?) Flash pen. This plastic pen has a metal ring and a
pocket clip and a white/gray circle at the top of the cap on the end.
Peggy succeeded in separating the cap from the pen. I put the cap back
on to avoid our both getting covered with black ink. Peggy removed
the cap. she began then trying to replace the cap, holding the pen in
her right hand and the cap in her left.
Peggy had a lot of trouble. She managed quite well inserting the pen in
the cap hole. BUT without good alignment, the pen would not go in
very far. She pressed harder. She removed the end and tried again.
After several tries, her persistence coupled with luck to permit the pen
insertion. She repeated the action five to ten times, refining her action
so that he re-insertions were quicker and more sure than the original
process. Somehow, the pen and the cap changed hands.
Peggy tried capping the pen with the cap in her right hand. She could
not do it. The reason is more surprising than the fact. The cap had
been turned around and she persisted in trying to insert the pen
through the white circle on the top of the cap. Can she not, does she
not distinguish a hole (whose appearance is black and round) from that
decorative circle (whose appearance is white and round)? The other
obvious common feature is that both are on the end of a cylinder.
If this is a discrimination failure, is the problem some non-salience of
color ? (Hard to believe.) Is it the complexity of three intersecting
features (being round, on a cylinder, and of different colors) ?
Perhaps it is not a discrimination failure but one of ignorance, i.e.
Peggy does not know that a covered hole prohibits insertion.
