Articles: The following articles cite or use data from the home shyness procedure.
Variable Names: Variable names from this database
have the prefix V1HSHY (V1HSH for one composite variable). The data
set has 785 test subjects and 72 variables. Three of these subjects
have no data attached to the test subject entry. Data were collected
by viewing video tapes of the home visit of 14 month old twins. The
variables include: Coder ID, Latency to First Approaching Stranger
across all 5 minutes, a Hesitation rating, 11 scores for each of the 5 minutes
(Approach/Talk, Proximity to Stranger, Plays with Strange Toy, Proximity
to Mother, Touches Mother, Clings to Mother, Plays with own Toys, Self-soothing
Behavior, Vocalizes, Cries), 13 composite scores 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 13 composite variables:
V1HSHLAT, V1HSHY58, V1HSHY59, V1HSHY60, V1HSHY61, V1HSHY62, V1HSHY63, V1HSHY64,
V1HSHY65, V1HSHY66, V1HSHY67, V1HSHY68, and V1HSHYPC.
V1HSHLAT:
This has the same value as V1HSHY1 (Latency to first
approaching stranger across all 5 minutes). If V1HSHY1 was coded as 999
(missing latency score, but data available), then V1HSHLAT was set to 300.
If there are no data other than the coder ID, then V1HSHLAT is recorded
as ‘.’ (missing).

Entry: (minutes 0 - 2)
The mothers were instructed beforehand by telephone not to be holding either child as she answered the door so that approaches to mother could be observed. One examiner filmed the children’s response to our arrival, beginning from the moment the door was opened and continuing for six minutes. Each mother was asked to identify “who was who” and the examiner then added what each of the children was wearing for future coding purposes. Mothers were then given consent forms and expense vouchers to complete. They were also asked at this time to not encourage the children in any way for the next four minutes as we wanted to see what the children were comfortable doing on their own. However, if a child wanted to be held during this time this was permitted.
Entry: (minutes 2 - 3)
The examiner not filming took out two toys, placing them near her but still easily accessible by the children and proceeded to play with each toy. She talked out loud about the toy but did not reference either child. If the children had approached the toys at this time or any time from minutes 2 - 5, they were allowed to play with the toys until minute 5.
Entry: (minutes 3 - 4)
At minute three, if the children had not approached the toys, the examiner called one child by name and invited the child to play with the toys. This was then repeated for the second child. The filmer followed each child in turn to record any responses.
Entry: (minutes 4 - 5)
At minute four the examiner picked up a toy and offered it to one of the children by extending her hand and asking if he/she would like to play with it. If the toy was not taken, it was placed either in the child’s hands or close to the child. This procedure was then repeated for the second twin.
Entry: (minutes 5 - 6)
At minute five, whether or not the children have touched or played with the toys, the examiner attempted to place an identifying vest on each child. Upon entering the study, each twin in the pair was assigned the color red or yellow. At 14-36 months, small vests which fastened in the back were worn by each child. At age five, these garments more resembled vests which buttoned in the front. And at age seven, name tags were used for identification purposes. At each age this procedure is used for coding shyness. The less shy children allowed the examiner to put the vest on themselves. The shyer children were those who needed mom’s help and the most shy were those children who refused to wear the garment.
