Health behavior, knowledge and attitudes among Swedish university students

A range of health behaviors was related to beliefs concerning health practices and health knowledge. A questionnaire dealing with health-related practices, health beliefs and knowledge of health risk factors was answered by 166 male and 179 female students aged 18–30 years at Stockholm University. Female students reported engaging in better health behavior than males. Beliefs about the importance of health behaviors were closely related to their frequency of occurrence. There was only a weak relationship between health behaviors and knowledge of specific health matters. It is concluded that health attitudes rather than health knowledge determine health behavior.     

Psychological well-being and homemaker vs. retiree identity among older women

Social roles have been a central focus in both sociological and developmental theories of adjustment in late life. Research on roles and well-being, however, has focused on earlier adulthood or on comparisons of tenuous roles (such as retiree) with institutional roles (such as employee), especially among men. The few studies comparing older women in the tenuous roles of homemaker and retiree all compare single-role women, and show contradictory results. One possibility is that multiple role identities are linked to greater well-being in older women, as they are among younger women. In this paper the life satisfaction, depression, and self-esteem of older women who consider themselves retired only, homemakers only, or both are compared. The sample includes 864 Black (N=242) and White (N=622) women ages 60 and over from a 1986 national survey. Retired women and homemakers did not differ in well-being; women who called themselves both had higher self-esteem and lower depression than single-role women. In analyses exploring what tenuous role content (daily activities) might explain group differences in well-being, do-it-yourself activities and volunteer activities were significant. Age, education, health, and marital status were also important factors. Recommendations include adopting a multiple role perspective with older women and encouraging their participation in instrumental, informal role activities to maximize well-being.Northwestern University     

Singles ads: Gender,social class,and time

The contents of 800 singles ads were examined. They were compared by the gender of the advertiser, the year of appearance (1991 and 1986), and the SES of the target readership (affluent and general). There were very few advertisers who listed themselves as black, so these ads were not included in the study. Gender differences were most important. Men were more likely to offer financial security and seek attractiveness. Women were more likely to offer attractiveness and seek financial security. The gender differences were in agreement with those reported for over a decade and from many geographical areas, although less than half of the advertisers mentioned either finances or attractiveness. Contrary to our hypotheses, the contents of mens' and womens' ads were more different in 1991 than they had been in 1986 and more in conformity with sexual stereotypes. Ads in a paper with an affluent readership were more likely to mention educational and financial status while ads in a paper with a readership throughout the metropolitan area were more likely to mention physical characteristics.     

The stability of individual differences in gender typing: Implications for understanding gender segregation

The stability of individual differences has important implications for understanding the origins of gender-typed behaviors. For example, if some children have a stronger preference for same-sex playmates (gender segregation) than do others, then exploring characteristics that may differentiate these children from their peers (e.g., preference for gender-typed toys or teacher proximity) should prove fruitful. Otherwise, research might be focused more appropriately on group-level processes or situational factors rather than individual differences. In the current study, 57 2 1/2- to 3-year-olds from middle-class Canadian homes were observed repeatedly during free play at their preschools. Four aspects of gender typing (gender segregation, use of masculine and feminine gender-typed toys, teacher proximity) were measured so that the stability of individual differences and relations among the measures could be assessed. Stable individual differences were found for all four measures among boys, and for two of the measures (feminine toy play, teacher proximity) among girls. In addition, boys who played most frequently with masculine toys rarely were observed in proximity to the teacher. However, there was no relation between gender segregation and the other indices of gender typing.     

A neural-network model enabling sensorimotor learning: Application to the control of arm movements and some implications for speech-motor control and stuttering

Summary Low-level motor control is defined as adapting an organism to the unique physical properties of its own limbs. The two-jointed arm serves to exemplify that effective low-level motor control demands a neurally mediated inversion of the dynamics, as well as of the kinematics, of a limb system. Reflex-like processing — that is, feedforword of either actual or predicted proprioceptive signals —is thereby assumed to be the principle of the dynamics control. As regards speech-motor control, the overall tool transformation is assumed to transform the force pattern of the articulatory muscles into speech sounds. Like the arm model, the vocal-tract transformation thus defined is also divided into two parts, namely the transformation relating the muscle forces to the mechanospatial states of the vocal tract (which is analogous to the forward dynamics including natural interarticulatory couplings), and the transformation relating the mechanospatial states to the speech sounds. Low-level speech-motor control, then, needs to invert both transformations, each of which can be learned by means of the self-imitation algorithm. Erroneous learning can fail to decouple interarticulatory coupling and therefore lead to abnormal feedback loops through the reflex-like operating neural network, which in turn can cause stuttering if audiophonatoric coupling is involved in learning.     

Social skills and depression in adolescent suicide attempters

The relationship among depression, social skills, and suicidal behavior was examined in a sample of 41 adolescents hospitalized in a general medical setting following a suicide attempt. These subjects were compared to 40 nonsuicidal psychiatrically hospitalized adolescents. Level of depression, assessed using the Children's Depression Inventory (CDI), and social skills, assessed via the Matson Evaluation of Social Skills with Youngsters (MESSY), were evaluated for all subjects. The suicide attempters and psychiatrically hospitalized patients were not found to differ on either the CDI or MESSY. However, multiple regression analyses revealed the factor scores of the MESSY to be related to depression in both patient groups. The data provide support for the relationship between social skills and depression. Results are also discussed in terms of the similarities between adolescent suicide attempters and nonsuicidal psychiatrically disturbed adolescents.     

The effects of contingent music and differential reinforcement on infantile colic

Infantile Colic is a behavioral syndrome characterized by paroxysms of excessive crying and increased motor activity, hypertonicity of the musculature, excessive flatus and erratic sleeping and feeding patterns. Ten to 40% of all infants are diagnosed as having Colic. The medical evidence to date does not justify any conclusions regarding the etiology or treatment of Colic. Typically, parents are advised to simply wait until Colic has run its course which is often 3-4 months. The behavioral program reported here was designed to increase behavior that competed with crying by reinforcing quiet alertness with music and parental attention. Concurrently, it attempted to inhibit excessive crying by a brief time-out procedure. A group of 8 infants diagnosed as Infant Colic were included in this study. The dependent variable, crying, was measured through direct observations based on hourly samples involving 30 observations of 2-min intervals. The independent variable consisted of a behavioral treatment package. A within-S reversal design was used to assess the functional properties of the treatment. The results show that across all 8 infants the introduction of the treatment package led to a substantial decrease in excessive crying of about 75% of the initial baseline. Further, a functional relationship was identified between the treatment and excessive crying behavior: crying decreased when the treatment was initially introduced, it resumed when the treatment was withdrawn and decreased again when the treatment was reinstated.
