tapes of the home visit of 14 month old twins. The variables
include: Coder ID, 11 Mother Child Teaching Task items, and a
comment field.

names from this database.
Cleaning: The data have been examined to ensure
that the values of the variables are within range. Compatibility of
the problem codes in the Home Visit Card (V1HVC) database with this database
will be examined.
Composites: There are currently no
composite variables defined from the Mother-Child Teaching Task
procedure.

Free-play
This measure is assessed in the 14, 20, 24 and 36 month visits as well as
the five year visit. The children are asked to go into a room with a door which
the mother closed after joining the children. The examiners at 14, 20 and 24
month visits assembled twelve toys in a standardized array on the floor. Then
the children and their mothers were called into the room. The mothers had been
instructed not to label any of the toys for the children nor to
initiate any interaction with the twins. She could respond if
approached by the children but
interactions were to be kept to a minimum. Appreciation of standards as well as
the twins methods of interacting with each other were assessed during this
procedure. At ages 36 months, five and seven years, the children were given
several vehicles, animals, and play school people to use in their free
play. This measure at all ages was fifteen minutes in length.
