5.* No separation of infant from mother at birth; nor during first two years of postnatal life (not greater than 24 hours).
6.* Breastfeeding for at least two years desirable--not less than one year.
7.* Carrying of infant on body of mother is frequent.
8.* No placement of infant/child in day care before two years of life.
9.* Little or no use of physical punishment as a common practice of discipline in child rearing.
10. Low maternal stress: low spousal conflicts; dual parents and/or significant extended family support, i.e. a happy family.
11. Early onset of sexual activity. (Age of onset and degree of sexual activity will be obtained. Subjects with early rather than later age of onset of sexual activity will be selected for this group).
12. Positive sex values.,e,g, masturbation is a normal healthy sex activity.
11. Whether and when being a single parent and nature of extended family support.
12. Time of onset and nature of sexual activity (Age of onset and nature/degree of sexual activity will be elicited) , as well as a history of sexual values.
The starred items are essential information variables. Given the design of this study where subjects are selected according to a developmental history of enriched vs impoverished Somatosensory Affectional Stimulation, it will be possible to address for the first time the consequences of such early sensory stimulation/deprivation upon brain development whether or not there are significant differences found on the circumcision variable. In short, the scientific outcome of this study is not limited to only the circumcision variable. Positive findings on the somatosensory affectional deprivation-stimulation continuum alone would fully justify the conduction of this pilot study.
