Observations, Interpretations, and Models

The Intimate Study Video Catalog

Tape Format Conversion Notes:
All original recordings were made on a reel-to-reel (R2R) Sony Port-a-pac. Early consumer electronics video recorders were vulnerable to various kinds of recording failures, of which we had a share. All usable R2R recordings have now been digitized. When the Infant Peggy Study tapes were converted to VHS format, the only Intimate Study tapes converted to VHS were those marked with an “X” in the final profile series. These tapes have been digitized earlier by Bob, as well as tapes 1, and 45-48. Subsequently (~Q4, 2009) the remaining port-a-pac tapes were digitized by the video recovery services of Rick Thomas (former web-site:, now defunct). Some tapes show difficult problems, but they are no longer completely lost in the limbo of changing technologies and deteriorating equipment. Most tapes are watchable. Some are usable for analysis, but not for show. They are in the preparation queue, but have a lower priority. Videos “unavailable” were impossible to convert from R2R sources to any format. They are lost. It was possible to create text analyses earlier, even of those videos where the recorder was droping frames, with the audio recordings made at the same time supplementing the fragmentary video record.

Videos of The Intimate Study (LC1 and LC2 both) were recorded at the MIT Logo Project in 1977. The adults interviewing Miriam and Rob were: Lab Director, Seymour Papert; Bob Lawler, father, doctoral student and Logo Research Assistant; and two Harvard doctoral students, with Laboratory experience in Piaget’s Center for Genetic Epistemology, Sheldon Wagner and Lawrence Miller. Margaret Minsky and Howard Austin occasionally played “camera man”; as did Gretchen Lawler, mother of the children.
For a TIS subset-index focused on Rob, see LC1c-video directory in LC1c-NLS.
