Comparisons of children with delayed and normal language at 24 months of age on measures of behavioral difficulties,social and cognitive development

This investigation compared a group of expressive language-delayed children with language-normal children of the same age (M = 25.7 months; SD = 0.8 months) on various measures of development and behavioral difficulties. Data were obtained through language sampling, direct developmental assessment, and maternal reports of children's development and behavior. Scores on measures of social and cognitive development for children with language delay were found to be significantly lower than normals. Further, maternal reports indicated that these children displayed significantly more behavioral difficulties overall than did the language-normal children. Specifically, the language-delayed children exhibited more symptoms of anxiety and depression, withdrawal, sleep problems, and other behavioral disturbances. In addition, children evaluated as expressive language delayed scored significantly lower on measures of receptive language, maternal ratings of communicative competency, and other indices of language proficiency. The results point to the centrality of expressive and receptive language development in relation to early-appearing behavior problems and other developmental milestones. With these findings in mind, early language intervention may not only promote language development, but also prevent the development or exacerbation of socioemotional problems. © 1998 Michigan Association for Infant Mental Health     

The Dynamics of Bimanual Circle Drawing

A bimanual circle drawing task was employed to elucidate the dynamics of intralimb and interlimb coordination. Right-handed subjects were required to produce circles with both hands in either a symmetrical (mirror) mode (i.e. one hand moving clockwise, the other counter-clockwise) or in an asymmetrical mode (i.e. both hands moving clockwise or counter-clockwise). The frequency of movement was scaled by an auditory metronome from 1.50 Hz to 3.25 Hz in8 (8-sec) steps.In the asymmetrical mode,distortions ofthe movement trajectories, transient departures from the target pattern of coordination, and phase wandering were evident as movement frequency was increased. These features suggested loss of stability. Deviations from circular trajectories were most prominent for movements of the left hand. Transient departures from the required mode of coordination were also largely precipitated by the left hand. The results are discussed with reference to manual asymmetries and mechanisms of interlimb and intersegmental coordination.     

Is It Still a Movement?

In this address from 1971, the second general secretary of the World Council of Churches (WCC), Eugene Carson Blake, sets out the challenges facing the WCC at the beginning of the 1970s, identifying three key changes within the ecumenical movement: a shift in power and decision making away from the Protestant churches of North America and Western Europe; an organization more representative of churches in Africa, Asia, and Latin America, and of Orthodox churches; and the ecumenical involvement of the Roman Catholic Church. It goes on to set out how the WCC, particularly since its conference on Church and Society held in Geneva in 1966, has been attempting to make Christian faith and morals relevant to a world experiencing rapid social, economic, and political change.     

Temperament and Gender: Correlates of Toddler Social Competence

The relation between temperament, gender, and social competence was examined in a sample of 202 children ranging from 12 to 36 months of age. Gender and specific characteristics of temperament corresponded more with toddler social competence than did a more general style of temperament. Females were rated by mothers and group caregivers as more socially competent than males on all four measures used in the study and significantly more so on three of these measures. Characteristics of temperament most closely associated with toddler social competence were approach/withdrawal, adaptability to change, and general quality of mood.     

Motor Schema Formation and Retention in Young Children

The variability-of-practice hypothesis, a major prediction of Schmidt’s (1975) motor schema theory, was tested in an attempt to investigate motor-schema formation. In addition, schema retention was observed after a 2-week retention interval. The task involved preschool children in tossing a bean bag for appropriate distance. Four treatment groups received 100 practice trials equally divided over five days. Variation was provided by varying the weights of the bean bags. The testing situations involved tossing a criterion weighted bean bag as well as a novel weighted bean bag which none of the groups had experienced previously. In addition, all groups were tested on a new but similar task. The results supported the variability-of-practice hypothesis in terms of schema formation and transfer to novel tasks in the same movement class. After a two-week retention interval, loss in performance was significantly less for the group with variability of practice than all other groups.     

General Strain Theory and the Relationship Between Early Victimization and Drug Use

This study uses general strain theory to examine the direct and indirect relationship between early victimization and drug use. Few previous studies measure strain as victimization. Also, past studies tend to combine drug use measures with delinquency measures. This study expands this research by operationalizing strain as early victimization and using measures of both frequency and onset of drug use. National Survey of Adolescents data is used to test the hypotheses. The results show that when youth are victimized they will use drugs more frequently and use drugs at a younger age. These relationships were only partially mediated by social bonds and negative emotions.
