Numerous studies indicate that intrinsic motivation predicts academic achievement. However, relatively few have examined various subtypes of intrinsic motivation that predict overall achievement, such as motivation for exercise and physical activity. Based upon the 16 basic desires theory of personality, the current study examined the motives of…

Resource dilution model suggests that as the number of children increases, parental resources for each child decline. Assesses whether resource dilution could explain the effect of siblings on intellectual development tests. Identifies flaws in recent critiques of this position, discussing it as an explanation for why children with few siblings…

The article reviews some of the conditions that might counteract decline in the intellectual development of gifted children and adolescents. (DLS)

An interview instrument was developed and validated to ascertain its utility as a measure of characteristics of home environments and its effect on a child's intellectual development. (JB)

Using data from a broader longitudinal study, this investigation explores within-subject and cross-generational stability of intellectual competence and the relationship of such stability to aggressive behavior. Data were gathered three times (when subjects' modal age was 8, 19, and 30 years). Initially, subjects included the entire population…

Discusses faith in the context of Catholic education as a way of knowing. Describes James Fowler's developmental theories showing the presence of a sequence in the way individuals experience intellectual growth. Presents six short theoretical characterizations showing a family in six stages of faith development. (DMM)

The family's values, attitudes, and ways of relating internally and externally determine its health-creating or destroying power. The family's overwhelming impact on human competence makes a strong case for premarital and parent education that prepares people for roles as spouses and parents. (SK)

Estimates confluence model of intellectual development for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of children and their parents and birth or adoption intervals were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Results suggest efficiency of the…

Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

Discusses the controversy of the relationship between birth order and intellectual performance through a detailed evaluation of the confluence model which assumes that the rate of intellectual growth is a function of the intellectual environment within the family and associated with the special circumstances of last children. (CM)

The confluence model shows the influence of family on intellectual growth. The decline of SAT scores is related to changing family patterns. Intellectual growth is lower for children with many siblings. The increase in average family size for the cohorts taking SATs between 1963 and 1980 caused scores to decline. (Author/VM)

The primary purpose of this study was to compare the effectiveness of infant test scores, Home Observation for Measurement of the Environment (HOME) scores, socioeconomic factors and maternal IQ as predictors of children's mental test performance. Additional purposes were to (1) determine the extent to which socioeconomic factors and maternal…

Ronald C. Johnson argued that if early environmental stimulation or deprivation has a significant effect on intellectual ability, then individuals who are genetically identical and who are exposed to a common early environment should resemble one another more closely in IQ than similar individuals who have not shared a common environment. Johnson…

Because the phenomenon of delayed graduation--the practice of prolonging the college career beyond the normal 4 years of undergraduate study--is so widespread researchers speculated that "continuers" might have certain common characteristics which would differentiate them as a group from "completers." The objective of this…

Reports that recent research has shown that family socioeconomic status is less a factor in a youngster's IQ score than is the non-economic home environment. (SL)
