Inferencing and television: A developmental study

Little research has been done to examine the cognitive processes engaged by television viewing in general, and with adolescent viewers in particular. The present study examined the extent of inferencing in adolescents' and young adults' interpretations of 3-min video segments taken from prime-time drama series and from rock music videos. It was predicted, and the results confirmed, that the less structured music video segments resulted in higher level inferencing than prime-time dramas. It was also found that young adults produced more higher-level inferences than adolescents, and prime-time drama led to more fact-based responses than music video. Correlations between television inferencing and scores on the Peel Lack of Closure Test were also examined to see if inferencing from video and from written text were related. Generally, these correlations were nonsignificant, confirming the hypotheses of other researchers that video inferencing involves unique knowledge structures that warrant further investigation.Received Ph.D. from Wayne State University.

Sex differences within the family: Studies of adolescent and parent family interactions

Sex differences in verbal family interactions were investigated in a group of 79 adolescents and parents from normal and psychiatric settings. The analyses were designed to study these differences in both generations, parent and adolescent. Parent and adolescent interactions with one another were observed in a semistructured, revealed-differences family discussion. All of the individual speeches were then scored with our Constraining and Enabling Coding System (CECS). Initial predictions involved both adolescent and parent differences. These hypotheses were only partially confirmed. The strongest findings pertained to parent sex differences, as we found strikingly higher levels of cognitive enabling speeches expressed by fathers and significantly more speeches addressed to fathers. We discuss several alternative interpretations of these findings. Perspectives included in our considerations are direction of effect and influences of task/context upon the expression of family sex differences.This study was supported through a grant from the National Institute of Child and Human Development (NICHD Grant No. R01 HD18684-02) and a Research Scientist Development Award No. 5 K-02-MH-70178 (Dr. Hauser) from the NIMH.Received M.D. from Yale University and Ph.D. from Harvard University (psychology).

Family influences,school behaviors,and risk for the later development of an eating disorder

Interviews were conducted with parents of 136 female and 45 male adolescents categorized into risk groups for the later development of an eating disorder. The family and school concomitants of risk status in females were demonstrated to be different from that in males. Risk group female adolescents rated family cohesion, parent-adolescent communication processes, and overall family satisfaction more negatively than the comparison group. Mothers of moderate risk group females reported lower family cohesion than the comparison group; there were no group differences for adolescent females in fathers' ratings of family measures. However, no group differences were found on any of the family measures between male risk and comparison males. For both females and males, there were no significant group differences in family history of eating and mood disorders, or alcohol dependence. Teacher ratings indicated relatively greater internalizing tendencies in the high-risk female group.This investigation was supported by NICHD Grant Number 1R01-HD24700 awarded to Gloria R.

Decade differences in rural adolescents' views of life possibilities

In a small-town high school ninth-graders were administered the same research instrument in 1967 and 1979. They listed events they thought would happen to them in the future, occupations, free-time activities, and people known, and answered questions related to perceptions of autonomy and family decision making. Except for the time span of future events, which remained between four and five years ahead, the later group showed many significant increases in cognitive possibilities, especially for occupations and free-time activities. Boys in 1979 perceived less family cohesiveness and girls more autonomy than their 1967 counterparts. Content analyses showed expansion of the girls' possibilities into formerly male-stereotyped occupations and an increase in perceptions of sexual and possibly antisocial activities, particularly among boys.Received his Ph.D. from the University of Minnesota.

Family contexts of pubertal timing

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.

Parental contexts of adolescent self-esteem: A developmental perspective

Relationships between parental behaviors and adolescent self-esteem were analyzed in a group of 95 early adolescents from multiple settings. The study was designed to investigate hypotheses regarding associations between observed parental interactions (e.g., accepting and devaluing) and adolescent self-esteem. Parents' verbal interactions with their adolescents were assessed through application of the constraining and enabling coding system to transcribed family discussions, generated through a revealed differences procedure. Adolescent self-esteem was measured with the Coopersmith Self-Esteem Inventory. Parent interaction-self-esteem associations were examined in the pooled sample, as well as in specific sub-groups based on gender, health, and ego development (measured by the Washington University Sentence Completion Test). Boys had more numerous associations between their self-esteem and parental interactions than girls, and psychiatrically ill boys had particularly high associations. Parental interactions were found to be most strongly related to adolescent self-esteem for adolescents at the lowest levels of ego development. Our findings are consistent with the view that increasing individuation in self-esteem regulation occurs during adolescent development, such that adolescents at higher levels of ego development evaluate themselves more independently of parental feedback than do their less mature peers.This study was supported through a Research Training Grant No. MH16259 (Dr. Isberg) from the NIMH, a grant from the National Institute of Child and Human Development (NICHD Grant No. 5 R01 HD18684-02), and a Research Scientis Development Award No. 5 K-02-MH-70178 (Dr. Hauser) from the NIMH.Received M.D. from Harvard University.

Urban youth under stress: Empirical identification of protective factors

Explored the influence of life stress as mediated or moderated by locus of control, family environment, social support, and coping style on psychological adjustment and school performance in 164 ninth graders from Baltimore. Gender differences in findings were shown. For boys, family cohesion was the only variable found to protect against the effects of stress. Family cohesion did not serve protective functions for girls, and along with overall social support, was associated with increased vulnerability to school problems. The report of problem-focused coping strategies exerted a number of protective functions for girls only. External locus of control was found to increase boys' and girls' vulnerability to the effects of life stress.

Parental criticism and young adolescent self-disclosure: A cross-cultural study

Criticism by mothers and fathers, as well as young adolescents' perceptions of parental criticism and their self-disclosure to parents, was assessed for a sample of 80 families. Of these, 40 were resident in Australia (20 Anglo-Australian and 20 Greek-Australian) and 40 were resident in Greece (20 professional and 20 working-class). There were no differences between the groups in amount of criticism by parents nor in adolescents' perceptions of criticism. Greek- and Anglo-Australian adolescents disclosed significantly less to parents than did the Greek adolescents. For Greek-Australian adolescents there was an inverse relationship between self-disclosure on a number of topics and perceived levels of parental criticism. The results were interpreted in terms of cultural differences between the groups and adaptive behaviors of the Greek-Australian adolescents.This research was supported by a University of Melbourne grant to the first author.Received Ph.D. from University of Melbourne.

Family processes and adolescent adjustment in intact and remarried families

This study examines whether family processes that predict positive and negative developmental outcomes are the same in intact and remarried families. Surveys were administered to 758 tenth graders from intact families and 95 from stepfather families. Measures of cohesion, democratic decision-making style, permissiveness, and conflict were used to predict self-rated depression, worry, and self-esteem. Remarried and intact families provide similar family environments for permissiveness and democratic decision making. Remarried families are more conflictual and less cohesive than intact families. In both family types, conflict had negative effects, and cohesion and democratic decision-making had positive effects on adolescents' adjustment. In remarried families, but not intact, permissiveness was related to higher self-esteem.Received Ph.D in developmental psychology from The University of Michigan.

Parents' and teachers' beliefs about adolescents: Effects of sex and experience

Three studies examine beliefs that parents and teachers have about adolescents. A distinction is made between category-based beliefs (concerning adolescents as a group) and target-based beliefs (concerning individual adoles cents). In Study 1, 90 late elementary and junior high school teachers indicated degree of agreement with a set of category-based statements about adolescents. Parents of early adolescents in Study 2 (N=1272) responded to category- and target-based statements. Study 3 compares the responses of teachers in Study 1 and parents in Study 2. Both teachers and parents endorsed beliefs that adolescence is difficult, and that adults can have an impact. Compared to fathers, mothers believed more in difficulty and in the negative effects of biological change on behavior. Parents of daughters believed adolescence is more difficult than parents of sons. Among teachers, amount of experience with adolescents was positively associated with the belief that adolescence is a difficult period of life. For parents, the effect of amount of experience was mixed. Experience had a greater impact on the category-based beliefs of teachers than parents. Possible influences on the origins and modification of beliefs are discussed.Received Ph.D. in psychology from The University of Michigan.

Coping styles of learning disabled adolescents and their parents

The study compares coping styles of 50 learning disabled and nonlearning dis-abled adolescents and their parents. Analyses indicate that learning disabled adolescents show less ability to appraise a source of stress and seek information in the various domains with which they are expected to cope. Also, they reveal a higher level of pessimism about problems in academic-related domains. Coping patterns of parents of learning disabled adolescents do not show clear differences from parents of nonlearning disabled. Yet mothers of learning disabled adolescents tend more to seek and accept help. Learning disabled adolescents' coping is clearly related to coping or more specifically to difficulties in coping of their parents. Results are discussed in the context of the special difficulties of the learning disabled during adolescence and the role their parents play during this developmental stage.Received Ph.

Parental support,coping strategies,and psychological adjustment: An integrative model with late adolescents

The purpose of this study was to apply an Integrative predictive model to examine interrelationships among parental support, adaptive coping strategies, and psychological adjustment among late adolescents. Findings using new measures of parental support and adaptive coping with 241 eighteen-year-old college freshmen supported hypotheses. Social support from both mother and father and a nonconflictual relationship between parents were positively associated with adolescents' psychological adjustment. Adolescents with high parental support were better adjusted and less distressed than were those with low parental support. Additionally, an integrative structural equation model showed that parental support was associated with psychological adjustment both directly and indirectly through a higher percent of approach coping strategies.This work was supported in part by grants from the Hogg Foundation for Mental Health, the University Research Institute, University of Texas at Austin, and the William T.

Age differences in adolescent future-oriented goals,concerns, and related temporal extension in different sociocultural contexts

The aim of this study was to investigate the extent to which differences in agegraded sociocultural contexts influence adolescent future-oriented goals, concerns, and related temporal extension. Ninety-five 13–14-year-old Australian boys and 104 girls, 87 16–17-year-old Australian boys and 81 girls, 67 13–14-year-old Finnish boys and 86 girls, and 56 16–17-year-old Finnish boys and 107 girls were investigated. Half of the subjects in each group came from an urban environment and half from rural regions. The subjects filled in the Hopes and Fears Questionnaire measuring the content and temporal extension of goals and concerns. Overall, the results showed that adolescent goals, concerns, and related temporal extension reflected the major developmental tasks of their own age and early adulthood. However, interesting cross-cultural, gender, and urban rural differences were also found, reflecting variation in societal options and cultural values. For example, Australians were more interested in leisure and more concerned about their own health and global issues. Later school transitions meant that in older age groups the Finnish adolescents expected goals related to their future education and occupation to be actualized later than Australian youths did. Because of a lack of career options, interest in a future occupation decreased with age among adolescents living in rural regions.Received Ph.D. from University of Helsinki.

Correlates of depressive symptoms in adolescents

The relationship between a number of social and cognitive variables and depressive symptomatology was evaluated in a sample of public middle-school and high-school students. The variables measured included stressful life events, locus of control, causal attributions, and means-ends problem-solving abilities. Higher levels of depression were found to be associated with a more external locus of control and a tendency to attribute outcomes to causes which are internal, stable, and global. Parental divorce and socioeconomic status were also found to be associated with higher levels of depression. No relationship was found to exist between either amount of life stress or problem-solving ability and depression. The implications of these results for delineating the underlying dimensions of depression in adolescents are discussed.Previously Dr. Siegel was in the Department of Clinical Psychology at the University of Florida.

Social psychological factors involved in adolescents' efforts to prevent their friends from driving while intoxicated

The present research examined factors that could be used to improve campaigns geared toward having adolescents prevent their friends from driving while intoxicated. Three areas were examined: (1) adolescents' ability to make accurate judgments of their friends' drunkenness using information about the number of drinks consumed and the time to consume, (2) their perceptions of the consequences that could ensue if they were to attempt to prevent their friends from driving while intoxicated, and (3) their knowledge of viable strategies if they were to attempt such interventions with their friends. The results show that adolescents have perceptual biases when using information about number of drinks and time to consume when making judgments of drunkenness, and that intervention attempts with friends are likely to result in confrontations. The implications of these findings for the timing and content of educational efforts is discussed.This research was supported in part by Grant AA0687502 from the National Institute of Alcohol Abuse and Alcoholism, and by the Center for Applied Research at the State University of New York at Albany.Received Ph.D. from University at Albany.

Hungarian adolescents' self-concept

Hungarian and United States adolescents' self-image was studied using the Offer Self-Image Questionnaire (OSIQ). In Hungary, 1,163 younger and older male and female adolescents were studied using a Hungarian translation of the OSIQ. Analyses of endorsement patterns of OSIQ items showed that Hungarian and American adolescents endorsed many items in the same way. Similarities in endorsement patterns were much more common between the two countries than were differences. Analyses of OSIQ scales showed that for most scales younger Hungarian adolescents reported better adjustment than younger American adolescents. Differences were not as great or reversed in the older age groups. Implications for cross-cultural studies of adolescent self-image were drawn based on these results.Received M.

Perceived parental rearing practices and styles of coping

In order to study the relation between parental rearing practices and coping dispositions, 75 females and 65 males completed the Children's Report of Parental Behavior Inventory and the COPE, a measure of general coping dispositions. Those who reported their parents had an authoritative rearing style (warmth and nurturance coupled with close monitoring and age-appropriate demandingness) used more social support and problem-focused coping than those who reported their parents used other rearing styles. In general, perceived parental warmth was related to the greater use of social support and problemfocused coping. Parental firm control was associated with increased problemfocused and reduced emotion-focused coping. The findings are discussed in the context of parental rearing styles indirectly influencing coping dispositions through their impact on feelings of competence and personal control.This research is based on a masters thesis conducted by the first author under the direction of the second author.

Adolescent attachment to parents and friends in relation to aspects of self-esteem

This study explored the relative influence of adolescents' perceptions of their attachment relationships with their mothers, fathers, and friends on three measures of self-esteem. The sample consisted of 493 New Zealand adolescents ranging from 13 to 19 years of age. Two dimensions of the attachment relationship were assessed: the utilization of emotional support and proximity, and the quality of affect. The major findings were as follows: utilization of emotional support and proximity from mothers, fathers, and friends was minimally related to overall self-esteem, coping abilities, and social competence. The quality of affect toward mothers and fathers was significantly related only to social competence. These findings suggest that adolescent self-esteem is more strongly associated with the quality of affect toward parents and friends than with the utilization of these target figures for support or proximity. The notion that parents and friends may contribute to different facets of self-esteem is discussed.This research is based on the first author's doctoral dissertation at the University of Auckland.Received Ph.D. from the University of Auckland, Auckland, New Zealand.

Adolescent women's developing identity: A study of self-definition in the context of family relationships

This study generated adolescent women's perception of their identity in relation to family members spanning three generations and related these perceived relationships to their sex-role orientation. Subjects were 20 firstborn university women from intact families. The methodology used multiple sources of information, including open-ended interviewing procedures, rating scales, and standard research measures of sex-role identity. Significantly more constructs empirically differentiated family by generation than by sex. Congruence of young women with both the parent and grandparent generation, relative number of masculine stereotypes produced, and personality traits of males and females were significantly influenced by the presence of a brother in the sibling generation. There was no relationship between family constellation and sex-role orientation. Feminine women were significantly more congruent with other females in their family than androgynous women. There was a linear trend for androgynous women to be increasingly individuated across the generations.Received her Ph.D. from Yale University.

Long-term effects of parental divorce on young adult male crime

The purpose of this study was to explore the long-term effects of parental divorce on young adult male crime from a longitudinal perspective. Four hundred and twenty-three males were randomly selected from a Danish birth cohort. Results of analyses of variance showed an initial significant relationship between divorce and young adult crime. However, the effects of divorce disappeared when further path analysis controlled for the effects of social class and father's criminality. In addition, time of divorce did not have an effect on later criminal behavior.Received her Ph.D. from Teachers College, Columbia University, in 1975.
