Body Dissatisfaction,Need for Social Approval,and Eating Disturbances Among Japanese and American College Women

A total of 171 Japanese and 144 American collegewomen (90% European American, 4% African American, 4%Asian or Asian American, and 2% other) completed theEating Attitudes Test (EAT-26), the Body Dissatisfaction Subscale of the Eating Disorder Inventory(EDI), and the Revised Martin-Larsen Approval MotivationScale (MLAM). Japanese women expressed the greaterdissatisfaction with their body but no more eatingdisturbances than American women. The need for socialapproval predicted the Japanese women's eatingdisturbances after controlling for the effects of bodyfatness (BMI) and body dissatisfaction. BMI was asignificant predictor of eating disturbances for Americanwomen but not for Japanese women. The results werediscussed in terms of their implications forcross-cultural similarities and differences incorrelates of disordered eating.     

Specific fears as predictors of generalized anxiety in children

The study investigated the relationship between fear and anxiety in childhood. One hundred fifty-one children aged 6 to 11 years (mean=8.7 years) completed the Fear Survey Schedule for Children-Revised (FSSC-R) and the Revised Children's Manifest Anxiety Scale (RCMAS). Correlational analyses demonstrated that the FSSC-R and each of the fear factors were significantly correlated with each other and with the RCMAS score. A stepwise regression procedure was used to determine if the FSSC-R or any of its five factors was significantly related to scores on the RCMAS. Results indicated that Factor 1 (Failure and Criticism) accounted for 31% of the variance (p < .0001)and Factor 2 (Fear of the Unknown) accounted for an additional 1% of the variance (p < .03)in the RCMAS scores. The relationship between these results and those from a similar study with adults (Goetsch, Tishelman, & Adams, 1987), as well as how the results add to an understanding of childhood anxiety, is discussed.This study was supported by BRSG Grant S07RR0714917 from the Biomedical Research Support Grant Program, Division of Research Resources, National Institute of Health, to the Research Foundation of the State University of New York at Binghamton.     

Biomechanics of the continuity and speed change during one revolution of the Fouette turn

The purpose of this study was to investigate the biomechanics of the continuity and speed change of the Fouette turn. This turn is one of the turns performed on one leg in classical ballet and is unique in terms of its continuity and change in rotational speed of the torso during one revolution of the turn. We filmed the turn as performed by seven experienced female ballet dancers in a clockwise direction on a force plate using three high speed cine cameras. In a 3D motion analysis of the turn, we found that the dancers mainly controlled the rotational speed by swinging the free or gesture leg laterally through torque exertion at the hip joint of the leg in clockwise and then counterclockwise directions, and that they supplied an angular impulse mainly to the gesture leg during the swing when flexing the supporting leg and keeping their foot flat on the plate. This supply of momentum enabled them to continue the turn compensating for the loss of the momentum of the body brought about in a rapid rotation phase when they were standing on tiptoe touching the foot of the gesture leg on the knee of the supporting leg.     

How do shy people expand their social networks? Using social surrogates as a strategy to expand one's network

The authors examined the use of social surrogates by shy people to expand their social network when entering a new environment, following Bradshaw's social surrogate hypothesis. The authors conducted a panel survey of 70 friendship pairs of students 7 months after they entered university. The results revealed that when a friend acted as a surrogate, the shy students extended their joint networks more. In contrast, not-shy students extended their networks regardless of whether a friend acted as a surrogate. These results indicate that even shy people can adjust indirectly to new social circumstances because they can expand their social networks by using a close friend as a surrogate.     

Human gestures trigger different attentional shifts in chimpanzees (Pan troglodytes) and humans (Homo sapiens)

Brain lateralization has been the matter of extensive research over the last centuries, but it remains an unsolved issue. While hand preferences have been extensively studied, very few studies have investigated laterality of eye use in non-human primates. We examined eye preference in 14 Campbell’s monkeys (Cercopithecus c. campbelli). We assessed eye preference to look at a seed placed inside a tube using monocular vision. Eye use was recorded for 100 independent and non-rewarded trials per individual. All of the 14 monkeys showed very strong preferences in the choice of the eye used to look inside the tube (mean preference: 97.6%). Eight subjects preferred the right eye and six subjects preferred the left eye. The results are discussed in light of previous data on eye preference in primates, and compared to data on hand preference from these subjects. Our findings would support the hypothesis for an early emergence of lateralization for perceptual processes compared to manual motor functions.     

Infants show a facilitation effect for native language phonetic perception between 6 and 12 months

Patterns of developmental change in phonetic perception are critical to theory development. Many previous studies document a decline in nonnative phonetic perception between 6 and 12 months of age. However, much less experimental attention has been paid to developmental change in native-language phonetic perception over the same time period. We hypothesized that language experience in the first year facilitates native-language phonetic performance between 6 and 12 months of age. We tested 6-8- and 10-12-month-old infants in the United States and Japan to examine native and nonnative patterns of developmental change using the American English /r-l/ contrast. The goals of the experiment were to: (a) determine whether facilitation characterizes native-language phonetic change between 6 and 12 months of age, (b) examine the decline previously observed for nonnative contrasts and (c) test directional asymmetries for consonants. The results show a significant increase in performance for the native-language contrast in the first year, a decline in nonnative perception over the same time period, and indicate directional asymmetries that are constant across age and culture. We argue that neural commitment to native-language phonetic properties explains the pattern of developmental change in the first year.     

Can we talk to robots? Ten-month-old infants expected interactive humanoid robots to be talked to by persons

As technology advances, many human-like robots are being developed. Although these humanoid robots should be classified as objects, they share many properties with human beings. This raises the question of how infants classify them. Based on the looking-time paradigm used by [Legerstee, M., Barna, J., & DiAdamo, C., (2000). Precursors to the development of intention at 6 months: understanding people and their actions. Developmental Psychology, 36, 5, 627-634.], we investigated whether 10-month-old infants expected people to talk to a humanoid robot. In a familiarization period, each infant observed an actor and an interactive robot behaving like a human, a non-interactive robot remaining stationary, and a non-interactive robot behaving like a human. In subsequent test trials, the infants were shown another actor talking to the robot and to the actor. We found that infants who had previously observed the interactive robot showed no difference in looking-time between the two types of test events. Infants in the other conditions, however, looked longer at the test event where the second experimenter talked to the robot rather than where the second experimenter talked to the person. These results suggest that infants interpret the interactive robot as a communicative agent and the non-interactive robot as an object. Our findings imply that infants categorize interactive humanoid robots as a kind of human being.     

Tobacco and alcohol tax relationships with suicide in Switzerland

Previous research has shown an empirical link between tobacco and alcohol use and suicide. If tobacco and alcohol use contribute to suicidal behaviors, then policies designed to reduce the tobacco and alcohol consumption may succeed in reducing suicides as well. To test this hypothesis, correlations for suicide rates with alcohol consumption, taxes on alcohol and tobacco in Switzerland were examined using sets of time-series data from Switzerland in 1965-1994. The tax on tobacco correlated significantly negatively with male standardized suicide rate. The tax on alcohol also correlated significantly with male standardized suicide rate in an autoregressive model. On the other hand, significant relationships with female suicide rate were not found. Policies designed to reduce tobacco consumption are consistent with a benefit of reducing suicides, particularly for men in this sample.     

Young children produce categorical false recall without activation of the lure items

Individuals who study a list of words that are all related to another word that is not presented (a lure word) sometimes produce a false memory of having studied the lure word. The false memories are observed in lists of words that are in the same category as (category list) or associated with (associative list) a word that was not presented in an attempt to elicit false recall. The present study investigated whether young children create these types of false recall. Following the study of a categorical list, false recall was elicited in young children to the same degree as in adults, but studying an associative list elicited false recall only in adults. Furthermore, categorically related lure words did not have a priming effect in young children. These results suggest that the categorical false recall is produced via a different mechanism from the associative false recall.     

Longitudinal Study of Mild Delinquency and In-School Problem Behaviors During Junior High School1

This research investigates repetitive problem behavior (in-school problems and mild delinquency) in Japanese junior high school students from their first to third year (12–15 years old) and examines the risk factors for repetitive problem behavior among parent–child relationships, school, individual, and lifestyle factors. An analysis of the longitudinal data of 470 students (Data Set 1) found that repeated problem behavior in school was affected by low self-control, poor relationships with teachers, and lack of parental monitoring. Repeated mild delinquent behavior was affected by parental violence, poor relationships with mothers, less sleep duration, and not belonging to club activities. Some students exhibited both mild delinquency and in-school problems. Students who experienced problem behavior 10 times or more in their second year had often experienced some problem behavior (1–9 times) in their first year. Analysis of the longitudinal data of 368 students (Data Set 2) showed that in many cases, students who exhibited repeated delinquent behavior in their second year continued to exhibit problem behavior after they became third-year students. Though the number of students with repetitive mild delinquency that was totally remedied in their third year was small, a low incidence of parental violence was seen as an antecedent factor for students who did not commit mild delinquency in their third year in spite of a high frequency of delinquency in their second year.
