The impostor phenomenon: self-perceptions, reflected appraisals, and interpersonal strategies

Three studies tested theoretical assumptions regarding the impostor phenomenon. In Study 1, participants completed measures of impostorism, rated themselves, and indicated how they thought other people regarded them. Contrary to standard conceptualizations of impostorism, high impostors were characterized by a combination of low self-appraisals and low reflected appraisals. Study 2 was an experiment designed to determine whether the behaviors associated with the impostor phenomenon are interpersonal strategies. Participants were told that they were expected to perform either better or worse than they had previously predicted on an upcoming test, then expressed their reactions anonymously or publicly. High impostors expressed lower performance expectations than low impostors only when their responses were public. When expectations for performance were low, participants high in impostorism responded differently under public than private conditions. Study 3 examined the possibility that high scores on measures of impostorism may reflect two types of impostors--true impostors (who believe that others perceive them too positively) and strategic impostors (who only claim that they are not as good as other people think). The results did not support this distinction; however, evidence for the strategic nature of impostorism was again obtained. Although people may experience true feelings of impostorism, these studies suggest that the characteristics attributed to so-called impostors are partly interpersonal, self-presentational behaviors designed to minimize the implications of poor performance.     

Subitizing and its subprocesses

 When people are presented with small sets of elements such as dots they can very easily determine their number. This ability has been called subitizing. The present paper reports results from four experiments. The discussion focuses on the question whether one or two psychological processes have to be assumed for this task of subitizing. Taken together our results support the two-process theories. In particular, a distinction between a process of separation and a process of enumeration is suggested. Experiments 3 and 4 support the canonical pattern hypothesis. Canonical patterns are processed substantially faster than noncanonical patterns. Furthermore, if a complex pattern can be broken down into small canonical patterns, then participants follow a partition and add strategy. Accepted: 22 December 1999     

Dyad Gender Differences in Preadolescents' Creative Stories

This study extended research on gender differences in creative stories written by individuals to creative stories written in collaboration with a same- or an other-gender peer partner. Participants were 104 preadolescent sixth graders, mostly White and middle class. Same- and other-gender peer partners (18 girl, 16 boy, and 17 mixed-gender dyads) worked together for 4 weeks to write creative stories based on mystery pictures. Story ideas were coded into one of seven categories (i.e., overt aggression, verbal aggression, relational aggression, prosocial behavior, negative emotion, positive emotion, and neutral/other). Boy dyads' stories included a greater proportion of overtly aggressive story ideas and a lesser proportion of prosocial story ideas than did girl dyads' stories. Mixed-gender dyads' stories contained a greater proportion of prosocial ideas than did boy dyads' stories. Findings are discussed in light of a social-contextual approach to gender differences and similarities.     

Adolescents' Possible Selves and Their Relationship to Global Self-Esteem

Recent research indicates that adolescent girls'self-esteem is lower than that of boys, and adolescence has been identified as a particularly problematic period for female self-esteem. However, many studies use global self-esteem measures that mask important differences within the domains of self-concept that contribute to self-esteem. Further, some self-esteem measures assess components of male self-esteem but overlook aspects of female self-esteem. The possible selves approach was used to identify categories of adolescent male and female self-concept that correlate with self-esteem. Subjects were 212 high-school students. The sample was primarily (96%)Caucasian. Results indicate that female self-esteem is related to perceived likelihood of hoped-for and feared possible selves in multiple domains, whereas male self-esteem is related only to the likelihood of one domain of hoped-for possible selves.     

Genetic and Environmental Influences on Personality: A Study of Twins Reared Together Using the Self- and Peer Report NEO-FFI Scales

ABSTRACT Previous behavior-genetic research on personality has been almost exclusively based on self-report questionnaire measures. The purpose of this research was to measure personality constructs via self- and peer reports on the items of the NEO Five-Factor Inventory (Costa & McCrae, 1989). The sample included 660 monozygotic and 200 same sex and 104 opposite sex dizygotic twin pairs. We collected self- and two independent peer reports for each of the twins. Our analysis of self-report data replicates earlier findings of a substantial genetic influence on the Big Five (h²= .42 to .56). We also found this influence for peer reports. Our results validate findings based solely on self-reports. However, estimates of genetic contributions to phenotypic variance were substantially higher when based on peer reports (h²= .51 to .81) or self- and peer reports (h²= .66 to .79) because these data allowed us to separate error variance from variance due to nonshared environmental in-fluences. Correlations between self- and peer reports reflected the same genetic influences to a much higher extent than identical environmental effects.     

Iconic memory and central processing capacity

Three experiments were conducted to assess whether or not iconic memory is influenced by demands placed upon central processing capacity. In Experiment 1 S was required to store material in short-term memory while performing an iconic memory task. In Experiments 2 and 3 S performed an auditory classification task concurrently with iconic storage. The three experiments did not reveal any significant impairment of iconic memory as a function of performing a subsidiary task. Similarly, performance on the subsidiary tasks did not suffer as a result of the concurrent iconic memory task.     

Quota vs positional power in four-person apex games

In coalition formation experiments, which coalitions will form and how players in coalitions will allocate their jointly gained rewards are typically predicted as a function of the players' relative power. In this paper, we isolated two logically independent sources of a player's power: the player's contribution to the rewards obtainable by coalitions of which he may be a member (“quota power”), and the number of distinct coalitions which a player may join (“positional power”). The separation of the two types of power is clearly shown in apex games, where a single player (Apex) attempts to lure any of the other players (Base) from the coalition of all Bases. A series of four-person computer-controlled apex and nonapex characteristic function games, varying with respect to the relationship of quota power to positional power, were played by 15 quartets of male players. Quota power was strongly manifested in all outcome measures, while positional power appeared only as a bias toward equal allocations of reward when coalitions among players of equal positional power formed. Neither of two social psychological theories that are applicable, pivotal power and weighted probability theory, predicted coalition frequencies. In a test of five solution concepts, the competitive bargaining set predicted payoff allocations better than either of the two aforementioned theories, the kernel, or an equal-split model.     

The dependency of the validity of information integration on cognitive variables and the judgement task

Simple models of information integration focus essentially on the combination of the components of information. This research investigated whether cognitive variables in the constructs of intelligence and cognitive complexity, as well as concentration, could predict the conditions of simple models of judgement. As additional predictors, the two qualitative variables [type of information] and [experience of the judgement task] were introduced. Subjects judged three types of stimuli using the pair comparison method. The conditions of the judgement models were analysed in the framework of the conjoint-measurement approach. Five different regression functions provided mediocre approximations to the 10 conditions of the models, when the 9 cognitive variables were considered. The small differences did not favour one of the five functions. The introduction of the qualitative predictor [type of information] improved the estimations more clearly than the experience of the judgement task, the effect of which was small.     

Zur logikabh?ngigkeit wissenschafts-theoretischer Paradoxien

Investigations in meta-theoretical topics such as the definability of disposition terms or the explication of qualitative and quantitative concepts of confirmation, as well as discussions of various systems of modal logic, e.g., deontic logic, often deal with a number of well known paradoxes. In general, classical logic is used in deriving the paradox of the ravens, Goodman's paradox, the paradoxes of derived obligation, etc. The questions whether these paradoxes depend essentially on the use of classical logic and whether they can be avoided by using intuitionistic or minimal logic are considered.
