Cleaning:  The data have been examined to ensure that the values of the variables are within range. Compatibility of the problem codes with the actual databases of each test will be examined.

Procedure Description:

Inhibition Room (Prohibition)

...all and completed two questionnaires while the child played freely for twelve minutes. The only other furniture in the room was a closed cabinet that is described next. Two video cameras were used to film the procedures. One remote controlled camera was mounted near the ceiling on the wall opposite the mother, and a second camera was operated from behind a one-way mirror in the wall behind the mother...

... Following this the third and final empathy probe began. The examiner returned to the room and feigned an injury to her foot as she repositioned a chair. After recovering, the examiner opened the cabinet, which housed a large discrepant object (a furry monster at 14 months and a tin can robot at 20 months). Presentation of the discrepant object was the third inhibition episode. The child was invited to approach and explore the object. If the child approached or after 2 minutes of encouragement, a voice was projected through a speaker in the cabinet. This discrepant object episode requires 3 minutes. The final 1-minute procedure involved another prohibition. A basket of colorful balls was placed in front of the child who was firmly told, “Now, don’t touch!” After a brief period of recovery from the prohibition, mother and child returned to the reception room and the second twin then accompanied the mother to the playroom.
