Predictors of nurturant parenting in teen mothers living in three generational families.

Direct and indirect effects of grandparents on maternal nurturance in teen mothers (TM) living in three-generational families were explored with path analytic techniques in a sample of 107 working-class families. Perceived support from the teen's mother, grandparents' nurturance toward the baby, and the presence of the grandfather as a father figure in the home were hypothesized as increasing TM nurturance. TM nurturance was found to be positively predicted by grandparent nurturance and negatively predicted by TM perceived support from her mother. The strongest predictor of TM nurturance was grandfather nurturance toward the baby.

Competence, delinquency, and attempts to attain possible selves.

The impact of impulsivity, possible selves, and social and communication skills on delinquent involvement in inner-city high school and incarcerated boys (aged 13-17, N = 230) was explored. Impulsivity, perceived attempts to attain possible selves, and balance in possible selves were hypothesized to directly influence delinquency. Social and communication skills were hypothesized to influence delinquency directly and indirectly through their effects on impulsivity, balance, and attempts to attain possible selves. These factors discriminated moderately well between high school and incarcerated youths. Impulsivity was an especially powerful predictor of self-reported delinquency among high school youths but not among incarcerated youths. The effect of other variables differed somewhat for different categories of delinquency (aggression, theft, hooliganism, and school truancy) and between subsamples, suggesting the importance of examining the subjective meaning of each of these behaviors for the individual in his social context.

Training disadvantaged preschoolers on various fantasy activities: effects on cognitive functioning and impulse control.

Preschool children were trained in 1 of 3 different types of fantasy activities over a school year. The effects of this training were evaluated over a variety of tasks measuring cognitive development and impulse control. The same basic experiment was replicated over 3 different years. Results indicated that physical enactment of fantasy experiences (viz., acting fairy tales or enacting previous experiences) had a sizable effect on many of these variables; while simply listening and discussing was often no more effective than the control condition that merely cut, pasted, etc. Evidence suggested that fantasy play remoter from reality was more facilitative for development than more realistically oriented fantasy play.

Regulatory effects of thymus humoral factor on T cell growth factor in aging mice.

The effect of thymus humoral factor (THF) on T cell growth factor (TCGF) production by T cells and the association between splenic macrophages and T cells from young (2-3 months) and old (20-24 months) mice in this respect were studied. Splenocytes were divided into three groups: stimulated with concanavalin A (Con A); preincubated with THF and then stimulated with Con A; or stimulated with Con A and thereafter incubated with THF. These cells were then examined for production of TCGF. Cells treated with Con A and THF as described above were passed on nylon wool to enrich T cell populations and added to mitogen-sensitized (Con A or lipopolysaccharide) adherent splenocytes of old and young mice in the following combinations: young adherent and young T cells; young adherent and old T cells; old adherent and young T cells; and old adherent and old T cells. The results demonstrated that: (A) cells of old mice produced less TCGF than the young; (B) preincubation of splenocytes or nylon-wool enriched T cells with THF increased the production of TCGF consistently in young mice, whereas in the old a significant increase was observed only in some cases; (C) depressed TCGF activity was observed when treatment with THF to splenocytes or nylon-wool enriched T cells from young and old mice was performed after Con A stimulation, and this was also more pronounced in the young; (D) the reduced level of TCGF in the old seemed to be related to a lesion in the T cell compartment, since adherent cells from old and young mouse spleens could support TCGF production by T cells from young mice and not from old.
