Children's use of semantic analysis in the interpretation of missing subjects: Further evidence against the MDP

Preschool and many older children often have difficulty understanding who carries out the complement action (e.g., to go in sentences such asMary promised John to go; this is so, even though they easily understand this information in sentences such asJohn told Mary to go. C. Chomsky (1969) proposed that children's errors arise from the overgeneral application of a purely structural Minimal Distance Principle. Maratsos (1974), however, hypothesized that children err by overgeneralizing a different principle which he called the Semantic Role Principle. According to this principle, the Goal-Recipient of the spoken message, not the closest noun phrase, is understood as the person who carries out the act referred to by the infinitival complement. The two studies reported here were designed to determine which of these principles children use. Preschool children were taught to understand a specially designed novel construction. The children then acted out sentences containing related but novel uses of the construction such that they would respond differentially according to which interpretive principle they used. The results strongly favored the Semantic Role Principle, rather than the MDP described by Chomsky (1969), or a related, more complex MDP described by Rosenbaum (1967). It is further discussed how children's formulation of the Semantic Role Principle, rather than the MDP, might arise from their prior analyses of related constructions, such as the imperative construction, rather than following from an innate preference, as suggested in Maratsos (1974).This research was supported by the NICHD under Grant #5 R01 HD09112-02 given to M. P. Maratsos.     

Maintenance of mother-child aversive relationships: A fresh look at an old controversy

Data were obtained from 46 mother-child pairs from the Child Behavior Institute (CBI) at the University of Tennessee. These mother-child dyads were referred for psychological help because of the child’s aversive behavior. Child-parent interactions were quantified using a multi-code, observational system. Correlational and multiple regression analyses (stepwise) were conducted to find the best predictor of the child’s aversive behavior. Results showed that the child’s aversive behavior was significantly correlated with the mother’s aversive, indiscriminate, and compliance behaviors. The regression analysis showed mother’s aversive behavior to be the best predictor of the child’s aversive behavior. Moreover, our results seem to point out that the compliance hypothesis is more effective in predicting child aversive behavior than the predictability hypotheses. It appears that since the two hypotheses are dealing with similar processes, they are more complementary than oppositional. This study used data collected by the Child Behavior Institute (CBI) at the University of Tennessee, Knoxville. The authors are indebted to Robert Wahler, Michael Smith, and Sue Dunn for their helpful comments on this paper.

The Radio Shack color computer in the experimental psychology laboratory: An evaluation

The Radio Shack color computer is examined from the viewpoint of capabilities needed to program, time, control, and acquire data from typical cognitive psychology experiments. Its capabilities are compared with those of the alternative inexpensive microcomputers discussed in an earlier article (Reed, 1980). The paper also includes a 6809 assembly language routine that permits the measurement of reaction times in video horizontal scan (HS = 4/63 msec) units without hardware modifications and an RSCC BASIC program for unbiased conversion of HS units to milliseconds.     

Personality patterns of adolescent poor and good sleepers

To determine whether poor sleepers have a unique personality constellation significantly different from that of good sleepers, a sample of 162 emotionally disturbed adolescent poor sleepers was compared to a sample of 153 emotionally disturbed adolescent good sleepers on standardized personality instruments. Poor sleepers were found to have a high incidence of neurotic psychopathology with personality patterns characterized by depression, fearfulness, inhibition, anxiety, and rumination. In contrast, good sleepers showed quasi healthy and/or characterological patterns. While this study does not resolve cause and effect relationships, it does establish a highly significant relationship between neuroticism and sleep disturbance for adolescent boys and girls, and also demonstrates a similarity of personality dynamics and patterns between adult and adolescent samples of patients with sleep disturbances.
