An emerging postural response: is control of the hip possible in the newly walking child?

Previous researchers have proposed that because of their slow muscle-response latencies, 1- to 2-year-old children are unable to control hip-dominant postural responses when responding to balance threats (G. McCollum & T. Leen, 1989). To test that proposition, the authors exposed 41 children to backward support-surface translations and recorded muscle activations and movement kinematics. Children between 10 months and 10 years of age stood on a platform that was unexpectedly moved. Passive hip-dominant responses were observed among the least experienced walkers. In contrast, older children produced an active response, signified by higher levels of abdominal and quadriceps muscle activity and accompanied by larger hip flexor torques. Greater success in withstanding large magnitudes of perturbations were associated with actively generated hip responses.     

Regulation of emotion and behavior among 3- and 5-year-olds

In this cross-sectional study, the authors examined the relationship between emotion and behavior regulation in 3- and 5-year olds. Eighty-seven children performed a compliance sorting task. The authors manipulated the demand for emotion regulation by presenting and then hiding toys (low) or making toys visible (high). Mothers and teachers rated children's coping responses. Five-year-olds sorted less in the high condition than in the low condition, and 3-year-olds spent equal time sorting in both conditions. Compliance was positively correlated with problem-focused coping and negatively correlated with emotion-focused coping. Correlations between emotion and behavior regulation were stronger for the 5-year-olds. Age groups were differently affected by the higher demands of emotion regulation, indicating that the child's resources for regulation interact with the task demands to determine behavioral outcome.     

The nature of social and personality psychology as reflected in JPSP, 1965-2000

A bibliometric analysis of the first 36 years (1965-2000) of the Journal of Personality and Social Psychology (JPSP) is presented. The authors analyzed the structure of JPSP on the basis of contents and other aspects related to productivity, such as growth in the number of articles and authors, and "invisible colleges." In 2001, JPSP articles were cited over 23,000 times. An increasing number of older, classic articles are cited, suggesting that there are an accumulating number of citations whose influence endures over time. JPSP articles have grown in length, number of studies included, number of references, and number of authors and have become more international with an increasing proportion of authors from outside the United States. The pattern of findings suggests an increasingly complex and mature science.     

Microstructure of eating behavior associated with Rorschach characteristics in obesity

The relationship between the microstructure of eating behavior and personality aspects according to the Rorschach Comprehensive System (Exner, 1991, 1993) was investigated among obese participants (N = 32). Eating behavior was measured using a computerized eating monitor, VIKTOR (Cabmek, Stockholm, Sweden), calculating initial eating rate and the eating curve. A higher initial eating rate reflecting eating drive was associated with Rorschach signs of stress overload according to the D Score and higher affective responsiveness to external stimuli seen in the Affective ratio. The stress overload may prompt eating, and affective responsiveness may be linked to appetite through a higher sensitivity to food stimuli, thus increasing eating drive. An accelerating rate of consumption during the meal was associated with intense emotionality and oral dependency, suggested by Pure C and Food responses.     

On the behavioral consequences of infrahumanization: the implicit role of uniquely human emotions in intergroup relations

Four experiments confirmed the hypothesis that people discriminate the out-group on the basis of the expression of uniquely human emotions. In Study 1, using a lost e-mail paradigm, the expression of a uniquely human emotion resulted in "nicer" replies when the sender was an in-group compared with an out-group member. The same pattern of results was obtained in Studies 2 and 3 using a conformity paradigm. In addition, perceived similarity was measured and proposed as a potential underlying mechanism (Study 3). Finally, using an approach-avoidance procedure, Study 4 showed that people not only deprive the out-group of positive consequences as in the former studies but that people also act against the out-group. The role of infrahumanization underlying prejudice and discrimination is discussed.     

Body image and eating attitudes among adolescent Chinese girls in Hong Kong

The study investigated the relation between body image and eating attitudes among adolescent girls in Hong Kong. A sample of 358 senior secondary school girls completed the measures assessing body-part satisfaction and behaviors associated with eating. Analysis indicated that even though only 4.8% of the girls were overweight, 85.16% desired to weigh less. These Chinese teenage girls were concerned about their weight, and the desire for slimness was widespread. Correlations indicated that higher Body Mass Index was associated with lower satisfaction with weight. Lower scores on weight satisfaction were associated with higher scores on attitudes of dieting and food preoccupation.     

Treating boys with low school achievement and behavior problems: comparison of two kinds of intervention

Children with low school achievement frequently have behavior problems and interpersonal difficulties that pose a risk for psychosocial maladjustment. 39 boys were assessed and randomly assigned to one of two group treatment conditions: (a) interpersonal cognitive problem-solving for whom training was provided through oral and written language activities that met children's social and academic needs and (b) a language workshop, during which only academic difficulties were treated. Parents of children in both groups received group attention. Posttreatment assessments indicated that boys in both conditions showed significant improvements on school achievement and behavior problems, as they were measured by behavior scales reported by mothers and by an academic achievement test. Children in the problem-solving group improved significantly more than the other group on most measures. These results suggest that work with interpersonal cognitive problem-solving skills combined with reading and writing activities is a useful means to produce improvements in child behavior and school achievement.     

The role of locomotion in the acquisition and transfer of spatial knowledge in children

The role of locomotion in the acquisition and transfer of spatial knowledge was investigated in 144 five-, seven- and eleven-year-old children. Two experiments were conducted in the Kiel locomotor maze. In the first experiment, one group of children explored the spatial layout by walking through the maze, while another learned the maze by surveying the layout. In the second experiment, children were exposed to one of two orientation tests in the maze, one of which could be solved using "landmark orientation", the other only using a "relational place orientation". Children sitting by the side of the experimental chamber surveying the maze needed fewer trials to learn the spatial layout than children exploring the environment in the locomotion condition, but in the orientation test demanding the "relational place orientation" children who had explored the maze in the locomotion condition outperformed the children in the non-locomotion condition. Results are discussed in the context of cognitive mapping models.
