The development of aggression in toddlers: A study of low-income families

The effort by developmental psychopathologists to understand the etiology of antisocial behavior has resulted in several significant findings. First, aggressive behavior is highly stable from early childhood into adolescence and adulthood. Second, parental factors including rearing practices and parental psychopathology, are correlated with childhood behavior problems. It was the aim of the present study to examine the correlates and stability of aggressive behavior in a sample of toddlers from low income families. Eight-nine mother-child dyads (52 boys and 37 girls) were observed in laboratory assessments when the child was 18- and 24-months old. Frequency and pervasiveness of aggression were coded from videotapes. Familial criminality, maternal depressive symptomatology, child noncompliance, and difficult child temperament were examined as contributors to the prediction of aggression in toddlers. Stability of aggression was moderate, especially for aggression occurring in low-stress situations. While there were few sex differences in the frequency and stability of aggression, there were marked differences in the correlates and predictors of aggression. Gender-specific, interactional models of the development of aggression are proposed.This study was supported by grants to Daniel Shaw and Joan Vondra from the following organizations within the University of Pittsburgh: the Mental Health Clinical Research Center for Affective Disorders, the Office of Child Development, the School of Education in conjunction with the Buhl Foundation, and the Faculty of Arts and Sciences. Portions of this paper were presented at the Meeting for the Society for Life History Research, Philadelphia, April 1992. The authors would like to acknowledge the contribution of Julie Alley, Jodi Chusta, and Kevin Cosley for their invaluable assistance in behavioral coding. Special thanks is given to the mothers and children who participated in this research.     

Verb Comprehension Deficits in Probable Alzheimer's Disease

Studies of lexical comprehension in probable Alzheimer's disease (pAD) have focused almost exclusively on nouns. In the following preliminary study, we examined whether lexical comprehension for verbs is also impaired in 25 pAD patients. The semantic meaning of motion verbs, cognition verbs, and perception verbs was assessed with a triadic comparison task. Structural meaning associated with these verbs was evaluated by asking the patients to judge the coherence of sentence frames that accept these verbs naturally or awkwardly. We found that pAD patients are significantly impaired at identifying semantic relations among verbs. pAD patients also encountered significantly more difficulty judging the coherence of sentences than control subjects. Correlation and regression analyses demonstrated that semantic characteristics of verbs are projected from the verbs' sentence frames in control subjects, but there was minimal evidence for such a structural–semantic relationship in pAD. We consider several possible explanations for our preliminary observations of an impairment that has consequences for processing both semantic and structural aspects of verb meaning.     

Assessing decision strategies using HyperCard

The use of “process-tracing” techniques for examining individuals’ decision strategies has been criticized widely for yielding results that are uninformative and often confounded. The present paper describes a new technique based on a “structural” approach that allows efficient assessment of finely discriminated decision strategies via a HyperCard program called DECOUT. The program presents individuals with an information matrix (e.g., describing five alternative pesticides on three attributes). Individuals are asked to choose the best or the worst alternative in the matrix for 12 problems. Information in the matrix is constructed so that choice of an alternative by an individual is uniquely associated with use of one particular decision strategy. The strategies include information integration, maximin, maximax, pessimism-optimism, and minimax-regret processes. An experiment using the program is described, and possible directions for future research and development are discussed.

Adaptive regression and types of cognitive flexibility

The relationship between adaptive regression and cognitive flexibility was explored in a group of 42 college students. Adaptive regression was measured with the Holt scoring system for the Rorschach. One type of cognitive flexibility was measured by Guilford's tests of divergent production (Word Fluency, Associational Fluency, and Alternate Uses) and a second type by Mednick's Remote Associates Test. Adaptive regression was found to be significantly positively related to the Remote Associates Test in males but not in females. Adaptive regression was found to be unrelated to divergent production tests. These relationships were not found to be mediated by Rorschach productivity or verbal intelligence. A two-stage process was proposed to account for the cognitive operations underlying adaptive regression and the Remote Associates Test. The first stage is seen as a generative (primary process) stage, while the second stage is seen as an evaluative (secondary process) stage. Possible reasons for sex differences were also discussed.     

Prominent publications in cognitive psychology

This article identifies the 50 publications in cognitive psychology that were most frequently cited in the professional literature between 1979 and early 1982. The characteristics of these publications are discussed, and comparisons are made with other relevant findings.     

Can attention give a left-ear advantage for verbal stimuli?

Three independent groups of 8 subjects listened monaurally to a randomized list of 50 common and 50 rare words and responded ‘yes’ to rare words. Responses were analyzed for correct identifications of rare words. A 50:50 group heard an equal number of words in right and left ears and gave a small but non-significant right-ear superiority. A 66:34 group heard nearly twice as many words in the right ear as the left and gave a significant right-ear superiority. A 34:66 group heard nearly twice as many words in the left ear as the right and gave a significant left-ear superiority. Responses were also analyzed according to signal-detection theory. Implications are discussed for theories of ear advantages.     

Women in families: feminist therapy and family systems*

Current family therapy has as its basis the concept of the family as a system. Systems theory has developed a set of explanations that are frequently functional in nature; they are often applied as though they assume that within a system a common goal is worked towards as in biological systems. For example, the concept of homeostasis is used in much the same way as Cannon (1929) used it to describe the mechanisms of stability within biological systems such as body temperature regulation. Here all the components of the system co-operate to maintain body temperature within certain limits. This functional assumption of a common aim amongst components of a system to achieve balance should be compared with a pluralist systems analysis which does not assume such commonality of goals. For example, a pluralist analysis could highlight the conflict inherent amongst different subsystems when one subsystem has more power than the other. At a theoretical level it can be seen that family systems theory has restricted itself to a limited set of assumptions about the explanatory concepts it uses. An analysis of women's psychology which has emerged through the developments of feminist therapy can enrich the theory and practice of family therapists.
