Children''s Behavioral Inhibition Over Age and Across Situations: Genetic Similarity for α Trait During Change

Ratings of behaviors pertaining to inhibition were observed for 130 twins participating in a longitudinal study. Ratings were available for four ages (12, 18, 24, and 30 months) and from three sources at each age: direct observations obtained in a laboratory setting, direct observations obtained in conjunction with infant mental testing, and a temperament measure from a questionnaire completed by parents. For the individual twins, the age-to-age correlations were in the moderate range (.26 to .64). The situation-to-situation correlations were generally in the same range (.17 to .64). When the twins were recombined into twin pairs, within-pair (intraclass) correlations indicated that monozygotic (MZ) twins were more concordant than dizygotic (DZ) twins for each of the behaviors at each of the ages. Also, the MZ twins were more concordant for the direction and degree of behavioral change from age to age or from situation to situation. These data provide additional evidence for the biological influence on behavioral inhibition, a characteristic that has been studied in temperament and personality research. The results suggest that the trait of behavioral inhibition and a change in the trait are genetically conditioned. In addition, it is suggested that the concept of trait be expanded to include the person-centered biological regulation of change.     

Taking a person-centered approach to personality: A latent-profile analysis of the HEXACO model of personality

Our study applies a person-centered approach to the HEXACO model of personality using latent profile analysis (LPA). While the traditional variable-centered approach assumes that the relations among variables within a population are homogenous, the person-centered approach identifies subgroups within samples that have similar scores on several variables of interest, in this case, the six factors of personality. Data from two independent samples were collected at a large North American university. The results of LPA revealed five distinct and interpretable profiles that replicated and were found to be consistent across both samples. We discuss how our findings attest to the meaningfulness of personality profiles, and suggest additional ways in which a person-centered approach might be applied in personality research.     

Is Character Fate,or Is There Hope to Change My Personality Yet?

Different perspectives on personality development propose a range of possible degrees to which traits are free to change, from hardly at all to very much. This essay reviews the empirical evidence on just how consistent and changeable personality traits are across the life course. To gain a thorough perspective on personality trait development, we review developmental studies that focus on three different types of change: rank‐order consistency, mean level change, and individual level change. Starting in late childhood, personality traits exhibit modest levels of rank‐order consistency that increase with age. In addition personality traits show mean level changes, especially in young adulthood, that are consistent with the idea of increasing maturity. Finally, despite these general trends in personality continuity and change, there is evidence that individuals may change in ways that contradict general trends and that these individual differences in change are related to life experiences.     

Behavioral change and consistency across contexts

The degree to which behavior changes across situations is often conflated with the cross-situational consistency of individual differences. The current study assesses the extent of behavioral change and consistency, the relationship between them, and variables associated with behaviors’ differing patterns of change and consistency. Two hundred fifty-six participants were observed in three different, three-person interactions. In line with previous research, behaviors showed a great deal of both change and consistency. Behavioral change across situations was unrelated to the degree to which individual differences in these same behaviors were maintained, demonstrating that behavioral consistency does not imply lack of situational adaptation. Behaviors rated as relatively broad and as relatively automatic showed more consistency; behaviors rated as relatively controlled showed more change.     

Assessment of individual differences in faking

In recent years, change scores obtained under neutral conditions and under faking-inducing conditions have become one of the main alternatives for operationalizing faking. A pending issue regarding these measures is the relevance of individual differences under similar conditions of pressure. This study proposes a simple approach based on the classic test theory that allows the issue to be rigorously assessed. The approach, from which three indices are derived, is based on a pre-test post-test design with a control group, and models the amount of change as an individual parameter. The proposal is applied to an empirical study in personality, and some interesting initial results are obtained.     

Measuring motivation multidimensionally: development of the Assessment of Individual Motives-Questionnaire (AIM-Q)

We report the development of the Assessment of Individual Motives-Questionnaire (AIM-Q), a new instrument based on an evolutionary psychology theory of human motivation. It provides multitrait-multimethod (MTMM) assessment of individual differences on 15 motive scales. A total heterogeneous sample of N = 1,251 participated in eight studies that evaluated the homogeneity, internal consistency, test-retest reliability, and MTMM convergent and discriminant validities of the AIM-Q's three methods. These studies generally support the overall strategy of assessing individual differences in multiple evolutionary-based motives with multiple methods. Additional validity studies are underway and, when validated further, the AIM-Q may offer a promising option for evolutionary psychologists and behavioral geneticists wanting to incorporate individual differences into their research but have had to use existing self-report measures of personality, which were not designed for such a purpose. It may also offer clinical and counseling psychologists an additional approach to personality measures for the prediction of behavior.     

Relationships matter in personality development: evidence from an 8-year longitudinal study across young adulthood

Personality-relationship transactions were investigated in a general population sample of young German adults with three assessments over 8 years. Four general findings were obtained. First, personality development was characterized by substantive individual differences in change. Second, bivariate latent growth models indicated that individual differences in personality change were substantially associated with change in peer and family relationships. Third, forming a partner relationship for the first time moderated the maturation of personality. This finding was replicated over two subsequent time intervals with independent subgroups. Fourth, higher neuroticism and higher sociability predicted which of the singles began a partner relationship during the next 8 years. The results confirm that individual differences in personality development predict and result from life transitions and relationship experiences.     

Situation-Behavior Profiles as a Locus of Consistency in Personality

Traditional approaches have long considered situations as "noise" or "error" that obscures the consistency of personality and its invariance. Therefore, it has been customary to average the individual's behavior on any given dimension (e.g., conscientiousness) across different situations. Contradicting this assumption and practice, recent studies have demonstrated that by incorporating the situation into the search for consistency, a new locus of stability is found. Namely, people are characterized not only by stable individual differences in their overall levels of behavior, but also by distinctive and stable patterns of situation-behavior relations (e.g., she does X when A but Y when B ). These if . . . then . . . profiles constitute behavioral "signatures" that provide potential windows into the individual's underlying dynamics. Processing models that can account for such signatures provide a new route for studying personality types in terms of their shared dynamics and characteristic defining profiles.     

Resilients,Overcontrollers, and Undercontrollers: The replicability of the three personality prototypes across informants

The study of patterns in personality structure reveals three replicable prototypes: Resilients, Overcontrollers, and Undercontrollers. The three prototypes were first identified in children using ratings based on the California Child Q‐set (see Block, 1971). Only recently, the three prototypes were replicated in self‐reports on questionnaires intended to assess the Big Five (see e.g. Asendorpf, Borkenau, Ostendorf, & van Aken, 2001). This paper addresses the question of whether the three prototypes are replicable across different data sources. Cluster structures in self‐, peer, and behaviour ratings, all based on the Big Five, were examined in a sample of 600 monozygotic and dizygotic twins ranging in age from 18 to 70 years. The three prototypes could be clearly identified in the self‐reports only, whereas in ratings by others only the Resilient prototype could be replicated. In both peer and behaviour ratings, the second and the third cluster reflected a Non‐desirable and an Average type. The analysis of cross‐data consistency revealed only moderate agreement in assignments of individual subjects to types. The findings suggest that personality types depend strongly on personality measures and informants. Copyright © 2003 John Wiley & Sons, Ltd.

Distinguishing between authenticity and personality consistency in predicting well-being: A mixed method approach

Introduction

The relationship between role personality consistency and well-being is somewhat ambiguous, with past research relying on methods confounded by social desirability or role stereotypes, or conflating consistency with authenticity.

Personality Change in Middle Adulthood: With Focus on Differential Susceptibility

Abstract

Little attention has been paid to middle adulthood in research on personality stability and change. In addition, previous research on individual differences in personality change has not fully explained its variability. This study focused on the differential susceptibility model, which suggests that individual susceptibility interacts with environmental factors and produces variability in outcomes, and investigated individual differences in personality change with a middle adult sample. A total of 1051 Japanese middle adults (M?=?41.61?years; SD = 5.31; range 30–50?years; 534 females) participated in this two-wave short-term longitudinal study. Latent change score model analyses revealed substantial mean-level declines in Agreeableness and Honesty–Humility. Moreover, the results showed that the influences of some life events on personality change are moderated for better and for worse by individual susceptibility to one’s environment. These findings suggest that the trends of personality development may differ between Western and non-Western countries and that differential susceptibility model may play an important role in deriving individual differences in personality stability and change.     

Ego Development during the Transition from Adolescence to Young Adulthood: A 9-Year Longitudinal Study

Although Loevinger's (1976) ego development theory represents a milestone approach to life-span personality development, little is known about ego development during the transition from adolescence to young adulthood, including the average gain in group means, whether individuals maintain their relative position to each other, and age-related changes in within-cohort variability. These issues are examined using the ongoing Block and Block Longitudinal Study. Across a 9-year interval—from age 14 to age 23—the findings indicate that: (a) the average person gains approximately 1.5 ego development steps, (b) within-cohort variability in ego development increases with age, (c) ego level at ages 14 and 23 is moderately related, (d) large individual differences exist in the timing and extent of ego development, and (e) the magnitude of change is smallest for individuals who have already reached the Self-aware level as adolescents. The findings suggest that the Self-aware level represents a developmental “hurdle” during the transition from adolescence to young adulthood. Possible explanations are explored in terms of pacers for ego development.

Individual Style of Activity and Adaptation to Standard Performance Requirements

This article introduces American psychologists to some approaches from the former Soviet Union to dealing with training and performance problems derived from indi- vidual differences in personality features. Our work considers some aspects of these problems based on Russian psychologists' study of personality within the framework of the theory of activity. The approach is known as "individual style of activity" and is fundamental to the analysis of practical achievement in Russian psychology. Sev- eral areas of applied research are presented to illustrate the approach. These studies examine the process of adaptation to objective requirements by participants with distinct individual features. This research does not emphasize the classification of individuals into particular groups for the purpose of selection; rather it emphasizes how to facilitate the adaptation of people with diverse personal features through the development of individualized methods of performance, teaching, and training. The findings have many important applications in education, sports, work, and other performance settings.     

Personality types in adolescence: change and stability and links with adjustment and relationships: a five-wave longitudinal study

We examined change and stability of the 3 personality types identified by Block and Block (1980) and studied their links with adjustment and relationships. We used data from a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents, thereby covering the ages of 12-20 years. In Study 1, systematic evidence for personality change was found, in that the number of overcontrollers and undercontrollers decreased, whereas the number of resilients increased. Undercontrol, in particular, was found to peak in early-to-middle adolescence. We also found substantial stability of personality types, because 73.5% of the adolescents had the same personality type across the 5 waves. Personality change was mainly characterized by 2 transitions: overcontrol → resiliency and undercontrol → resiliency. The transitional analyses implied that the resilient type serves more often as the end point of personality development in adolescence than do overcontrol and undercontrol. Analyses of the personality type trajectories also revealed that the majority of adolescents who change personality type across 5 years made only 1 transition. Study 2 revealed systematic differences between resilients and overcontrollers in anxiety. Stable resilients were less anxious over time than were stable overcontrollers. Further, change from overcontrol to the resilient type was accompanied by decreases in anxiety, whereas change from the resilient type to overcontrol was accompanied by an increase in anxiety. Similarly, systematic differences between personality types were found in the formation of intimate relationships.     

Personality Trait Change in Adulthood

ABSTRACT— Recent longitudinal and cross-sectional aging research has shown that personality traits continue to change in adulthood. In this article, we review the evidence for mean-level change in personality traits, as well as for individual differences in change across the life span. In terms of mean-level change, people show increased self-confidence, warmth, self-control, and emotional stability with age. These changes predominate in young adulthood (age 20–40). Moreover, mean-level change in personality traits occurs in middle and old age, showing that personality traits can change at any age. In terms of individual differences in personality change, people demonstrate unique patterns of development at all stages of the life course, and these patterns appear to be the result of specific life experiences that pertain to a person's stage of life.     

Temperament, personality, and developmental psychopathology as childhood antecedents of personality disorders

To contribute to the case for a dimensional conceptualization of psychopathology in general and maladaptive personality or personality disorders in particular, the present paper reviews the evidence for a dimensional representation of childhood temperament and personality. The review of temperament and variable-centered as well as person-centered approaches to childhood personality leads us to propose five broadband dimensions that capture individual differences in children and adolescents: extraversion, emotional stability, agreeableness, conscientiousness, and openness/intellect. Our analysis of the CBCL (Achenbach, 1991) and the DIPSI (currently under development at Ghent University), two dimensional models for childhood psychopathology, suggests two common broadband factors, internalizing and externalizing. The relations between the dimensional representation of childhood temperament/personality and psychopathology are documented with data from general population and clinical samples of children and adolescents. The article concludes with a proposal on how the higher-order dimensions emerging from studies of adaptive and maladaptive individual differences in childhood could be integrated in a common dimensional model.
