The variability among students at the same grade level in the total number of Individually Prescribed Instruction (IPI) units in mathematics and reading mastered during the year 1967-68 is presented in statistical form. Tabulations of the degree of variance show that individualization does occur within the IPI program. (SP)

This paper was part of a symposium in which research on Project 100,000 was summarized. The report presents information on three major HumRRO projects concerned with training and performance of men of varying ability levels. The first project compared on-the-job performance of military personnel of varying ability levels. The second project…

Two studies were reported which attempted to estimate the stability and construct validity of human salivary response as a measure of individual differences (IDs) in physiological arousal. Twenty-second base line estimates and 20-second response levels to four drops of lemon juice were measured, with the former value being removed from the latter…

A computer simulation model was fitted to human laboratory data for the Missionaries and Cannibals task to explain the effects upon problem performance of giving a hint and the effect of solving problems a second time after a successful solution has been achieved. (Author/DEP)

Games can be modified by teachers or children to suit individual developmental needs. (PBS)

A conceptual framework for individual differences in sensory structure and processing is outlined which provides a theoretical integration of multivariate, psychophysical, and experimental studies of sensation. (Author)

Reflectivity-impulsivity was examined with 52 high IQ students (mean age 16). No significant differences in mean IQ were found among fast accurates, slow accurates (reflectives), fast inaccurates (impulsives), and slow inaccurates, suggesting the reflectivity dimension may not be useful for high IQ individuals.

Builds on a 1983 pilot study of the sequence of feelings and behaviors in divorce, using 141 divorced persons. Model employed three process stages, three filing categories, and three variables. Results of phase two indicated modal frequency of responses at various stages. Recovery lag between actives and passives was not confirmed as in 1983…

Examined whether peak alert time is related to compatibility for college roommates. Data from 66 male pairs and from 55 female pairs of roommates revealed that pairs who were similar on self-reported peak circadian alertness had higher levels of rapport. (Author/NB)

Presents a model for understanding how individuals manifest conflict in group psychotherapy and the major changes in technique following from this model. Proposes that individuals make unconscious decisions to expose conflict when it is safe to do so, as opposed to traditional dynamic theory. A clinical example demonstrates technical innovations…

Reports a short-term longitudinal study of children at 13 months and at 18 months which supports the belief that patterns of emotion reflect early, persistent individual differences; they also reflect a developmental trend toward increasing complexity of emotional responses. (Author/NH)

Examined the relationship between religiosity and unmarried adolescent fatherhood in unwed Black adolescent fathers (N=43) and nonfathers (N=50). The results indicated that the fathers were more likely to be responsive to nongroup modes of institutionalized religion, whereas the nonfathers' religious involvement was likely to be within…

Compared persons who attended career workshops and those who registered but did not attend. Interviews with nonattenders showed 45 percent had forgotten or felt discouraged, 38 percent gave environmental reasons, and 17 percent indicated they had already met their goals. (JAC)

A total of 114 infants at three age levels (11, 18, and 28 weeks) were rated by their mothers on a termperament questionnaire and subjected to a habituation procedure. Results suggest that subject loss in habituation studies may be the result of nonrandom individual difference factors and not just the result of temporary fluctuations in state.…

Comparisons of the Wechsler Intelligence Scale-Revised and Wechsler Adult Intelligence Scale-Revised were made in a sample of male delinquents to determine whether they would show differences in the degree to which the P>V sign occurred on them. A larger split between mean Verbal and mean Performance IQ was found on the WISC-R than on the WAIS-R.…
