Importance of fathers' parenting to African-American toddler's social and cognitive development

The present study examined the degree to which parenting attitudes and behavior (i.e., self-reported warmth, restrictiveness, and behavioral sensitivity as assessed during a freeplay session) were related to toddlers' development. Results showed a restrictive attitude was negatively related to social and cognitive development, whereas paternal sensitivity was positively related to aspects of social development that are less dependent on language skills (e.g., motor and daily living skills). Fathers of girls exhibited greater sensitivity in their freeplay interactions than fathers of boys. More globally, the present research demonstrates important relations between the parenting attitudes and behavior of low- to working-income African-American fathers and young children's development, and similarities to White, middle-income fathers.     

Dysnomia in Alzheimer's disease: an evaluation of neurobehavioral subtypes.

The relative influence of perceptual and semantic features on naming performance was investigated with reference to the neurobehavioral profiles displayed by patients with Alzheimer's disease (AD). Forty-one patients were classified as manifesting a verbal, visual, or global subtype based upon their pattern of neuropsychological functioning. Perceptual characteristics of to-be-named pictures were varied by manipulating the amount of line detail, whereas semantic qualities were varied by altering word frequency norms. All AD subtypes were less accurate than normal elderly controls in naming low frequency pictures. Patients and controls took longer to name low frequency and high complexity pictures, and this effect was comparable across the AD groups. Patients with predominantly visual deficits were significantly slower in naming than controls, and those with verbal impairments made a higher proportion of semantic naming errors when compared to patients displaying visual or severe global impairments. These results suggest that deficits in semantic processing contribute to naming dysfunction in AD, and they highlight the importance of examining dissociations among neurobehavioral subtypes.     

TRAINING PREDELINQUENT YOUTHS AND THEIR PARENTS TO NEGOTIATE CONFLICT SITUATIONS1

In response to parental requests for assistance in dealing with adolescent problem children, three parent-child pairs were taught negotiation responses to hypothetical conflict situations using behavior rehearsal and social reinforcement. The negotiation process was separated into component behaviors that were practised during simulations by each youth and his parent under the direction of trainers. Results indicated that (a) the procedures were successful in training youths and their parents in negotiation behaviors that produced agreements to conflict situations, and (b) these behaviors generalized to actual conflict situations in subjects' homes.     

The equity restoring components of retaliation

Previous research has shown that retaliation can be an effective means of restoring equity to the relationship between a harm-doer and his victim The present study investigated the equity restoring properties of two components of retaliation the harm-doer “paying the price” for his harmful act, and the victim being given an opportunity to inflict harm Equity was restored to the relationship between the harm-doer and his victim when the harm-doer believed that his victim would be given an opportunity to inflict harm either upon the harm-doer or a neutral party When the harm-doer was led to believe that he would be retaliated against by someone other than his victim, equity restoration did not occur. The suggestion was made that the crucial factor in equity restoration may be the way in which the harm-doer thinks the relationship is viewed by his victim     

The orthogonal approximation of an oblique structure in factor analysis

A procedure is derived for obtaining an orthogonal transformation which most nearly transforms one given matrix into another given matrix, according to some least-squares criterion of fit. From this procedure, three analytic methods are derived for obtaining an orthogonal factor matrix which closely approximates a given oblique factor matrix. The case is considered of approximating a specified subset of oblique vectors by orthogonal vectors.Part of this research was carried out while the author was a psychometric fellow at the Educational Testing Service, Princeton, New Jersey.     

A method of scalogram analysis using summary statistics

A method of Guttman scalogram analysis is presented that does not involve sorting and rearranging the entries in the item response matrix. The method requires dichotomous items. Formulas are presented for estimating the reproducibility of the scale and estimating the expected value of the chance reproducibility. An index of consistency is suggested for evaluating the reproducibility. An illustrative example is presented in detail. The logical basis of the method is discussed. Finally, several methods are suggested for dealing with non-dichotomous items.Lois K. Anderson assisted the author materially in the many computations required for this paper.
