This research examined how a contextualist approach to personality can reveal social interactional patterns that are obscured by gender comparisons of overall behavior rates. For some behaviors (verbal aggression), girls and boys differed both in their responses to social events and in how often they encountered them, yet they did not differ in overall behavior rates. For other behaviors (prosocial), gender differences in overall rates were observed, yet girls and boys differed more in their social environments than in their responses to events. The results question the assumption that meaningful personality differences must be manifested in overall act trends and illustrate how gender differences in personality can be conceptualized as patterns of social adaptation that are complex and context specific.

This research examined how syndromal approaches to assessment can obscure differences between children in the quality of their social interactions. Mixed boys (high for externalizing and internalizing problems) showed heterogeneity in the responses they evoked from others: For one subgroup, aggression and withdrawal evoked aversive responses from others, and even prosocial behavior evoked hostile peer responses; for the other, aggression and withdrawal evoked positive peer responses. Externalizing boys also showed heterogeneity in the patterning of their evoked responses. Within-group heterogeneity was not explained by boys' syndrome scores but was linked to their reactions to specific antecedent events. The results illustrate how a contextualized analysis of behavior can reveal distinctive social interactional patterns that underlie similar overall rates of problem behaviors.

Two studies examined how "syndromal" approaches to assessment confound differences between individuals in the person and situation variables that contribute to their behavior. In a field study, a widely used instrument was found to be sensitive to the base rates of boys' aggression but, as expected, did not discriminate between boys who were similar in their behavior base rates but different in their social environments and how they responded to them. A laboratory experiment replicated this finding and demonstrated that social observers discriminated between targets on the basis of their functional properties even though syndrome scores did not. The results clarify how syndromal methods can obscure situational factors, conflict with people's social knowledge, and reinforce the view that syndromes exist "in the individual" rather than in person-environment interactions. Implications for developing more contextually sensitive instruments are discussed.

A contextualized approach to psychopathology that focuses on children's responses to events rather than overall behavior output was examined. Teachers rated boys in special education classrooms using a standardized syndromal instrument and one that assessed boys' social environments and their responses to them. Externalizing and mixed (aggressive and withdrawn) syndrome groups showed distinctive response patterns that could not be derived from syndrome scores, with externalizers showing aggression in response to aversive events, and mixed boys showing contextually anomalous responses to positive events. The externalizing and mixed groups each consisted of functionally distinct subgroups that were not detected using syndrome measures. The results clarify how syndromal measures can confuse psychologically distinct children and demonstrate the utility of a teacher-report method that is efficient to administer and sensitive to contextual influences.

In contrast to assessment approaches that conceptualize traits as generalized response tendencies, this research develops a conditional approach that conceptualizes traits as patterns of relations between contexts and behaviors. Using extensive observations of social interactions, this study investigated internalizing, externalizing, and mixed-syndrome children identified by T. M. Achenbach's (1993) measures. Children in these groups differed in the patterning of their responses to social contexts and in the likelihood of encountering them. Mixed-syndrome children showed a distinctive behavior pattern consisting of aggressive and withdrawn responses to nonaversive contexts. The results demonstrate how measures of overall tendencies confound person and environment influences and obscure differences between children that are revealed by contextualized measures. The need to incorporate contexts more fully into clinical assessment is discussed.

In nomothetic analyses, the cross-situational consistency of individual differences in social behavior, assessed in vivo in a camp setting, dependent on the similarity in the psychological features of situations. As predicted by the social-cognitive theory of personality, idiographic analyses revealed that individuals were characterized by stable profiles of if ... then ...,situation-behavior relationships that formed "behavioral signatures" of personality (e.g., he aggresses when warned by adults but complies when threatened by peers. Thus, the intraindividual organization of behavior variation across situations was enduring but discriminatively patterned, visible as distinctive profiles of situation-behavior relationships. Implications were examined for an idiographic reconceptualization of personality coherence and its behavioral expressions in relation to the psychological ingredients of situations.

Consistency in the natural organization of aggressive and prosocial (constructive) behavior, assessed repeatedly in vivo over a summer in a residential camp for children, was predicted from situational and personal characteristics. Similarity of situations in the types of competencies they demand in part predicted cross-situational consistency in individual differences in aggressive behaviors (Study 1). Study 2 examined the effect of cognitive competence on the discriminative patterning of behavior variation across situations. More cognitively competent Ss showed such discriminative patterning, which was reflected in greater Person X Situation interaction variance in their prosocial behavior.

To examine the effects of the relationships between behavior and the situation in which it occurs, we manipulated such relations and exposed subjects to them. Impressions were similar when based on the behaviors presented with situations unspecified (e.g., child hits) or when the situations in which they naturally occurred were specified (e.g., child hits when provoked). However, when situations were specified, subjects' impressions more accurately predicted individual differences in the children's actual levels of overall aggressive behavior. When the veridical situation-behavior relations were increasingly altered, the targets were perceived as being less plausible and increasingly maladjusted and odd, and correlations decreased between the perceived level of the children's aggressiveness and their actual aggressive behavior. Thus, both personality impressions and predictive accuracy were influenced by the relations between the target's behaviors and their situational contexts.

This article demonstrates that features identified in the classic expertise literature are shared by experts in the domain of social cognition. Clinical novices and experts were presented with multiple observations of children's behaviors and the situations in which they occurred. Three types of target personalities were created: a prototypical aggressive target whose behavior patterns corresponded to those displayed by actual aggressive children in natural social situations; an inverse target whose behaviors systematically violated those of the aggressive target; and a random target whose behaviors did not vary systematically across situations. Performances of experts and novices were examined in recall, prediction, and impression formation tasks. Experts and novices did not differ in recall as measured by a free recall task, but the experts' predictions of targets' behaviors were more closely tied to actual behavior than novices' predictions for both the aggressive and inverse targets. As predicted, the accuracy of experts' and novices' predictions was comparable for the random target, whose behaviors did not vary systematically over situations. The results suggest that a key element of clinical expertise is the ability to detect patterns of covariation between antecedent events and target behaviors. Like experts in highly structured domains, clinical experts appeared to encode target information at a more abstract level than novices did and displayed more flexibility in interpreting theory-inconsistent information. We discuss the relation between these findings and previous evidence of clinicians' inferential shortcomings.

The view that the intuitive psychologist exaggerates the consistency of personality implies that dispositional constructs are condition-free summary statements about generalized behavioral tendencies. This article considers the alternative view that dispositional constructs summarize specific condition-behavior contingencies. Despite their condition-free appearance, the dispositional constructs used by child and adult observers in their personality descriptions were hedged by modifiers that reflected knowledge of the variability of behavior. Children's descriptions of their aggressive and withdrawn peers included probabilistic hedges that indicated uncertainty about the occurrence of behaviors (person sometimes does x). Adults made dispositional attributions with greater certainty, but more often modified them with conditional statements which identified when dispositionally relevant behaviors might be observed (person does x when y). Content analyses of these conditional statements revealed that adults systematically linked specific categories of conditions (e.g., aversive interpersonal events) to specific categories of social behavior (e.g., aggressive acts). The results help to clarify how people may hedge dispositional terms in ways that reflect their sensitivity to covariation between situations and behaviors.

In this article, we develop a bounded rationality view of the relation between person perception and social behavior. Two theses of this approach are that behaviors vary in their significance to observers, and that observers pursue bounded rather than global utility in forming personality impressions. Observers are expected to be sensitive to targets' overall behavioral tendencies and to the variability of their behavior across situations, but both sensitivities are bounded, being greater for behaviors that directly affect observers' outcomes. In two investigations involving extensive hourly and 6-s observations, we examined the bounded utility of people's impressions of personality, demonstrating how impression accuracy is linked to the significance of behaviors. Observers were sensitive to the organization of aggressive behaviors, but less sensitive to the organization of withdrawn behaviors, even when the consistency of those behaviors was comparable. The results clarify the relation between people's inferential shortcomings in laboratory paradigms and the bounded utility of person perception in the natural environment.

A conditional approach to dispositions is developed in which dispositional constructs are viewed as clusters of if-then propositions. These propositions summarize contingencies between categories of conditions and categories of behavior rather than generalized response tendencies. A fundamental unit for investigating dispositions is therefore the conditional frequency of acts that are central to a given behavior category in circumscribed situations, not the overall frequency of behaviors. In an empirical application of the model, we examine how people's dispositional judgments are linked to extensive observations of targets' behavior in a range of natural social situations. We identify categories of these social situations in which targets' behavior may be best predicted from observers' dispositional judgements, focusing on the domains of aggression and withdrawal. One such category consists of subjectively demanding or stressful situations that tax people's performance competencies. As expected, children judged to be aggressive or withdrawn were variable across situations in dispositionally relevant behaviors, but they diverged into relatively predictable aggressive and withdrawn actions in situations that required the social, self-regulatory, and cognitive competencies they lacked. Implications of the conditional approach for personality assessment and person perception research are considered.
