Maturation of personality in adolescence.

The present research assesses adolescent personality maturation by examining 3 measures of change and stability (i.e., mean-level change, rank-order stability, and profile similarity) of Big Five personality traits, employing data from a 5-annual-wave study with overlapping early to middle (n = 923) and middle to late (n = 390) adolescent cohorts. Results indicated that mean levels of Agreeableness and Emotional Stability increased during adolescence. There was mixed evidence for increases in Extraversion and Openness. Additionally, rank-order stability and profile similarity of adolescent personality traits clearly increased from early to late adolescence. For all change facets, the authors found evidence for gender differences in the timing of adolescent personality maturation, as girls were found to mature earlier than boys.

Five types of personality continuity in childhood and adolescence.

This study examines 5 types of personality continuity--structural, mean-level, individual-level, differential, and ipsative--in a representative population (N=498) and a twin and sibling sample (N=548) of children and adolescents. Parents described their children on 2 successive occasions with a 36-month interval using the Hierarchical Personality Inventory for Children (I. Mervielde & F. De Fruyt, 1999). There was evidence for structural continuity in the 2 samples, and personality was shown to be largely differentially stable. A large percentage had a stable trait profile indicative of ipsative stability, and mean-level personality changes were generally small in magnitude. Continuity findings were explained mainly by genetic and nonshared environmental factors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Genetic effects explain the stability of psychopathic personality from mid- to late adolescence.

This study examined the importance of genetic and environmental influence for the stability of psychopathic personality between mid- and late adolescence. The target sample consisted of all 1,480 male and female twin pairs born in Sweden between 1985 and 1986. Psychopathic personality was measured with the Youth Psychopathic Traits Inventory (YPI; H. Andershed, M. Kerr, M. Stattin, & S. Levander, 2002) when the participants were 16 and 19 years old. Results showed that the 3 psychopathic personality dimensions were stable at different levels of analysis and linked to a stable higher order general factor (i.e., psychopathic personality factor). Genetic factors contributed substantially to the stability of this general higher order factor, whereas environmental factors were of little importance. However, the authors also found specific genetic stability in the Callous/unemotional and Impulsive/irresponsible dimension. Thus, the model provides evidence for etiologic generality and etiologic specificity for the stability of psychopathic personality between mid- and late adolescence.

Consistency of maternal behavior from infancy to preadolescence.

Continuing studies on the effect of the mother on child development, the present investigation establishes that (a) interviews with the mother elicit comparable data to that gleaned from direct observation of the mother-child interaction and (b) at least with regard to the love-hate dimension, there is a consistent pattern of relationship between mother and child during infancy and in to preadolescence. Such validation was not found with regard to the factor of the autonomy-control continuum. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effect of early cognitions on cigarette and alcohol use during adolescence.

The present study predicts cigarette and alcohol use in adolescence from the development of children's cognitions in the elementary years. Using latent growth modeling, the authors examined a model using data from 712 participants in the Oregon Youth Substance Use Project, who were in the 2nd through 5th grade at the 1st assessment and followed for 6 annual or semiannual assessments over 7 years. Growth in children's prototypes and subjective norms in the elementary years (Times 1 through 4) were related to their substance use in adolescence (Time 6) through their willingness and intentions (Time 5) to smoke and drink. Across the sample, for both substances, the intercept and slope of prototypes were either indirectly related to use through willingness or directly related to use. Both the intercept and slope of subjective norms were indirectly related to use of both substances through both willingness and intentions and directly related to cigarette use. Results suggest that elementary children have measurable cognitions regarding substance use that develop during the elementary years and predict use later in adolescence. These findings emphasize the need for prevention programs targeted at changing children's social images of substance users and encouraging more accurate perceptions of peers' use.

Maternal personality, parenting cognitions, and parenting practices.

A community sample of 262 European American mothers of firstborn 20-month-olds completed a personality inventory and measures of parenting cognitions (knowledge, self-perceptions, and reports about behavior) and was observed in interaction with their children from which measures of parenting practices (language, sensitivity, affection, and play) were independently coded. Factor analyses of the personality inventory replicated extraction of the 5-factor model of personality (Openness, Neuroticism, Extraversion, Agreeableness, and Conscientiousness). When controlling for sociodemographic characteristics, the 5 personality factors qua variables and in patterns qua clusters related differently to diverse parenting cognitions and practices, supporting the multidimensional, modular, and specific nature of parenting. Maternal personality in the normal range, a theoretically important but empirically neglected factor in everyday parenting, has meaning in studies of parenting, child development, and family process.

Conceptual model for maternal behavior among polydrug cocaine-using mothers: The role of postnatal cocaine use and maternal depression.

This study examined the association between maternal cocaine use and maternal behavior and tested a conceptual model predicting maternal insensitivity during mother-infant interactions. Participants included 130 mother-infant dyads (68 cocaine-exposed and 62 noncocaine-exposed) who were recruited after birth and assessed at 4-8 weeks of infant age. Results of model testing indicated that when the effects of prenatal cocaine use were examined in the context of polydrug use, maternal psychopathology, maternal childhood history, and infant birth weight, only postnatal cocaine use and maternal depression/anxiety were unique predictors of maternal insensitivity during mother-infant interactions.

Conformity behavior of schizophrenic subjects with maternal figures.

4 groups of 10 Ss each were used: (a) a group of Nondrug Poor Premorbid schizophrenic Ss, (b) a group of Drug Poors, (c) a group of hospitalized Alcoholics, and (d) a group of Normal control Ss. S was placed in a 2-choice situation, and asked to indicate his preference, over a number of trials, after having learned the preference of a cold, domineering, maternal figure. Conformity was measured in terms of 3 relatively independent response attributes. The results indicate that, as compared to the Nondrug schizophrenics: (a) the Drug schizophrenics manifested less conformity, (b) the Normals were uninfluenced, and (c) the Alcoholics tended to disagree with the negative mother. All groups were equally accurate in their perception of the 2 mothers. (24 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The necessary and sufficient conditions of therapeutic personality change.

This reprinted article originally appeared in Journal of Consulting Psychology, 1957(Apr), Vol 21(2), 95-103. (The following abstract of the original article appeared in record 1959-00842-001.) "For constructive personality change to occur, it is necessary that these conditions exist and continue over a period of time: (1) Two persons are in psychological contact. (2) The first, whom we shall term the client, is in a state of incongruence, being vulnerable or anxious. (3) The second person, whom we shall term the therapist, is congruent or integrated in the relationship. (4) The therapist experiences unconditional positive regard for the client. (5) The therapist experiences an empathic understanding of the client's internal frame of reference and endeavors to communicate this experience to the client. (6) The communication to the client of the therapist's empathic understanding and unconditional positive regard is to a minimal degree achieved."

The stability of the self-concept in adolescence.

"A study of the stability of the self-concept over two years in adolescence resulted in the following conclusions:… Relative stability… was demonstrated… between Q sorts… . Subjects whose self-concept was negative at the first setting were significantly less stable in self-concept than subjects whose self-concept was positive… . Subjects who persisted in a negative self-concept over the two year period gave evidence of significantly more maladjustment." 16 refs.

Interactions Between Mothers and Children: Impacts of Maternal and Child Anxiety.

This study, an expansion of an earlier study of parenting behaviors of anxious mothers, examined the relationship of both mother and child anxiety disorders to mother behavior in parent-child interactions. Participants were 68 mother-child dyads with children ranging in age from 7 to 15 years. Mothers and children completed diagnostic evaluations and engaged in conversational tasks; behaviors were rated by coders who were blind to diagnosis. Mothers of anxious children, regardless of their own anxiety, were less warm (p     

Individual differences in the development of sensation seeking and impulsivity during adolescence: Further evidence for a dual systems model.

Consistent with social neuroscience perspectives on adolescent development, previous cross-sectional research has found diverging mean age-related trends for sensation seeking and impulsivity during adolescence. The present study uses longitudinal data on 7,640 youth from the National Longitudinal Study of Youth Children and Young Adults, a nationally representative sample assessed biennially from 1994 to 2006. Latent growth curve models were used to investigate mean age-related changes in self-reports of impulsivity and sensation seeking from ages 12 to 24 years, as well individual differences in these changes. Three novel findings are reported. First, impulsivity and sensation seeking showed diverging patterns of longitudinal change at the population level. Second, there was substantial person-to-person variation in the magnitudes of developmental change in both impulsivity and sensation seeking, with some teenagers showing rapid changes as they matured and others maintaining relatively constant levels with age. Finally, the correlation between age-related changes in impulsivity and sensation seeking was modest and not significant. Together, these results constitute the first support for the dual systems model of adolescent development to derive from longitudinal behavioral data.

Covariation of color and luminance facilitate object individuation in infancy.

The ability to individuate objects is one of our most fundamental cognitive capacities. Recent research has revealed that when objects vary in color or luminance alone, infants fail to individuate those objects until 11.5 months. However, color and luminance frequently covary in the natural environment, thus providing a more salient and reliable indicator of distinct objects. For this reason, we propose that infants may be more likely to individuate when objects vary in both color and luminance. Using the narrow-screen task of Wilcox and Baillargeon (1998a), in Experiment 1 we assessed 7.5-month-old infants' ability to individuate uniformly colored objects that varied in both color and luminance or luminance alone. Experiment 2 further explored the link between color and luminance by assessing infants' ability to use pattern differences that included luminance or color to individuate objects. Results indicated that infants individuated objects only when covariations in color and luminance were used. These studies add to a growing body of literature investigating the interaction of color and luminance in object processing in infants and have implications for developmental changes in the nature and content of infants' object representations.

The kids are alright: Growth and stability in personality development from adolescence to adulthood.

This longitudinal study provides a comprehensive analysis of continuity and change in personality functioning from age 18 to age 26 in a birth cohort (N?=?921) using the Multidimensional Personality Questionnaire (A. Tellegen, 1982). Data were analyzed using 4 different methods: differential continuity, mean-level change, individual differences in change, and ipsative change. Convergent evidence pointing toward personality continuity, as opposed to change, was found. The personality changes that did take place from adolescence to adulthood reflected growth in the direction of greater maturity; many adolescents became more controlled and socially more confident and less angry and alienated. Consistent with this, greater initial levels of maturity were associated with less personality change over time. The results indicate that the transition from adolescence to young adulthood is marked by continuity of personality and growth toward greater maturity.

Blue notes: Coping by music listening predicts neuroticism changes in adolescence.

It is important to understand distinctive developmental specificities of coping in adolescence and how these can relate to personality development. Adolescents can actively use music listening as a coping resource to maintain emotional stability and this is likely to influence their personality development. The aim of this study was to examine if interactions between 3 styles of coping by music listening (emotion oriented, problem oriented, and avoidance/disengagement oriented) could predict changes in adolescent neuroticism. This 2-wave longitudinal study followed 336 adolescent girls and boys over a 6-month period. In adolescents combining high neuroticism (baseline) and low avoidance-oriented coping, problem-oriented coping predicted lower neuroticism. In adolescents combining high neuroticism (baseline) with high avoidance-oriented coping, problem-oriented coping predicted higher neuroticism. In adolescent girls presenting high avoidance-oriented coping, emotion-oriented coping predicted higher neuroticism. Overall, avoidance/disengagement coping by music listening may represent a short-term risk/precipitating factor of increasing neuroticism in adolescence.

Intellectual and personality correlates of test anxiety.

Ss were administered: Sarason's True-False Test Anxiety Scale, Bendig's 20-item version of the Taylor Manifest Anxiety Scale, Sarason's Lack of Protection Scale, and Edwards' Social Desirability Scale. These data were intercorrelated with 13 measures of intellectual performance. "Although all correlations between anxiety and intellectual measures were small, there was a consistent, significant tendency for… [Sarason's True-False Test Anxiety Scale] to correlate negatively with the intellectual measures. No similar tendency was observed for the… [other scales]." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stability and change in temperament during adolescence.

This study assessed genetic and environmental contributions to temperament during adolescence within the Nonshared Environment and Adolescent Development project (NEAD; D. Reiss, J. M. Neiderhiser, E. M. Hetherington, & R. Plomin, 2000). NEAD is a national study that includes twins and other sibling types who vary in regard to genetic relatedness. Seven hundred twenty sibling pairs (aged 12.1-13.5 years) participated at Time 1, and 395 sibling pairs (aged 14.7-16.2 years) participated again at Time 2. At both Times, mothers and fathers rated their children's temperament (emotionality, activity, sociability, and shyness). At Times 1 and 2, genetic and nonshared environmental factors accounted for variance in temperament, whereas shared environmental contributions were negligible. However, at Time 1, genetic contributions were inflated, and shared environmental contributions were masked if sibling contrast effects were not taken into account. At Time 2, sibling interaction effects had little impact on estimates of genetic and environmental contributions to temperament. Last, temperament stability was primarily explained by genetic factors, whereas both genetic and nonshared environmental factors accounted for change.

Role of muscle tension in personality theory.

The relationship of muscle tension to personality is reviewed through the 19th century to the present. Although the methods of measurement are often only indirectly related to one another certain trends emerge. Skeletal muscle tension tends to be high: in the hyperactive person during emotional stress, in psychotic and neurotic groups, and particularly in disorders in which anxiety is the major concomitant. The mechanism of symptom specificity, whereby a particular muscle develops symptoms due to its constant state of sustained contraction, is also discussed. (3 p. ref.)

Mothers' and children's expectations for adolescence: The impact of perceptions of an older sibling's experience.

The present study examined the role of perceived experience with an older child in mothers' expectations for subsequent children's adolescence as well as the impact of perceived experience with an older sibling on young adolescent children's expectations for their own adolescence. Participants were 305 sixth- and seventh-grade adolescents and 287 of their mothers. Participants were interviewed via telephone. For both mothers and children, the quality of experience with an older child/sibling was a better predictor of target-based expectations for the young adolescent than was the simple presence or absence of an older sibling. In some cases the link between quality of experience with an earlier born adolescent and mothers' expectations for the target child's adolescence was modified by the target child's temperament. In general, the results support a modeling hypothesis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
