Sex differences in value priorities: Cross-cultural and multimethod studies.

The authors assess sex differences in the importance of 10 basic values as guiding principles. Findings from 127 samples in 70 countries (N = 77,528) reveal that men attribute consistently more importance than women do to power, stimulation, hedonism, achievement, and self-direction values; the reverse is true for benevolence and universalism values and less consistently for security values. The sexes do not differ on tradition and conformity values. Sex differences are small (median d = .15; maximum d = .32 [power]) and typically explain less variance than age and much less than culture. Culture moderates all sex differences and sample type and measurement instrument have minor influences. The authors discuss compatibility of findings with evolutionary psychology and sex role theory and propose an agenda for future research.

Individual differences in judging deception: Accuracy and bias.

The authors report a meta-analysis of individual differences in detecting deception, confining attention to occasions when people judge strangers' veracity in real-time with no special aids. The authors have developed a statistical technique to correct nominal individual differences for differences introduced by random measurement error. Although researchers have suggested that people differ in the ability to detect lies, psychometric analyses of 247 samples reveal that these ability differences are minute. In terms of the percentage of lies detected, measurement-corrected standard deviations in judge ability are less than 1%. In accuracy, judges range no more widely than would be expected by chance, and the best judges are no more accurate than a stochastic mechanism would produce. When judging deception, people differ less in ability than in the inclination to regard others' statements as truthful. People also differ from one another as lie- and truth-tellers. They vary in the detectability of their lies. Moreover, some people are more credible than others whether lying or truth-telling. Results reveal that the outcome of a deception judgment depends more on the liar's credibility than any other individual difference. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Experts' and novices' abilities to detect children's high-stakes lies of omission.

We investigated adults' abilities to detect lies told by 3- to 6-year-old children. Expert forensic interviewers and novices watched videotapes of children who either lied or told the truth about their parent's transgression, rendered a dichotomous judgment of whether the child lied, rated their confidence in that judgment, and rated the children on various characteristics. Adults detected lies with greater than chance—but not impressive—accuracy, regardless of expertise level. Older children's lies were more detectable by experts than were younger children's. Adults were more confident in their judgments about older than younger children. Confidence in lie/truth judgments was not significantly correlated with actual lie detection accuracy.

Individuals and dimensions in children's judgment of same and different.

Used the 2-choice transposition problem to examine children's judgments of "same" and "different." When instructed to choose "the same" object in the test phase, kindergartners (n = 24) chose the same dimensional value whereas 3rd graders (n = 24) chose the specific stimulus which had been positive during training. When instructed to choose "the different" or "a different" object, both groups chose on the basis of individual identity. Ontogenetic changes in children's use of individual identities and dimensional values, and the relation between linguistic and cognitive factors, are discussed.

Sources of group and individual differences in emerging fraction skills.

Results from a 2-year longitudinal study of 181 children from 4th through 5th grade are reported. Levels of growth in children's computation, word problem, and estimation skills by means of common fractions were predicted by working memory, attentive classroom behavior, conceptual knowledge about fractions, and simple arithmetic fluency. Comparisons of 55 participants identified as having mathematical difficulties to those without mathematical difficulties revealed that group differences in emerging fraction skills were consistently mediated by attentive classroom behavior and conceptual knowledge about fractions. Neither working memory nor arithmetic fluency mediated group differences in growth in fraction skills. It was also found that the development of basic fraction skills and conceptual knowledge are bidirectional in that conceptual knowledge exerted strong influences on all 3 types of basic fraction skills, and basic fraction skills exerted a more modest influence on subsequent conceptual knowledge. Results are discussed with reference to how the identification of potentially malleable student characteristics that contribute to the difficulties that some students have with fractions informs interventions. Also, results will contribute to a future theoretical account concerning how domain-general and domain-specific factors influence the development of basic fraction skills.

The role of intentional forgetting in reducing children's retroactive interference.

Preschool and kindergarten children's retention of stories was examined in the presence of interfering information and instructions to forget. Children learned 2 stories and, 24 hr later, were asked to recall the 1st or 2nd story learned. Some of the children were instructed, either following acquisition or just prior to the retention test to forget the 2nd, or interfering, story. A model was used to isolate storage and retrieval effects, and the results showed that (a) retroactive interference affected both storage- and retrieval-based forgetting rates for the younger children but only storage-based forgetting rates for the older children, (b) intentional forgetting reduced retroactive interference primarily by attenuating storage-based forgetting regardless of age, (c) intentional forgetting instructions were effective only at acquisition for preschoolers but at both acquisition and retention for kindergarteners, and (d) all children recalled the to-be-forgotten story as well as they recalled the to-be-remembered story. These results are interpreted in terms of reorganization and distinctiveness effects in storage. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children's moral evaluations of reporting the transgressions of peers: Age differences in evaluations of tattling.

The way children evaluate the reporting of peers' transgressions to authority figures was investigated. Participants, ages 6–11 years (N = 60), were presented with a series of vignettes, each of which depicted a child who committed either a minor transgression (such as not finishing the vegetables at lunch) or a more serious transgression (such as stealing from a classmate). Participants were asked to evaluate the decision of a child observer who either did or did not report the transgression to a teacher. Younger children considered reporting to be appropriate for both types of transgressions, but older children considered reporting to be appropriate for major transgressions only. Results are interpreted with reference to (a) a changing peer culture in which the social cost of reporting transgressions increases and (b) a developmental change in children's cognitive capabilities.

Developmental and individual differences in pure numerical estimation.

The authors examined developmental and individual differences in pure numerical estimation, the type of estimation that depends solely on knowledge of numbers. Children between kindergarten and 4th grade were asked to solve 4 types of numerical estimation problems: computational, numerosity, measurement, and number line. In Experiment 1, kindergartners and 1st, 2nd, and 3rd graders were presented problems involving the numbers 0-100; in Experiment 2, 2nd and 4th graders were presented problems involving the numbers 0-1,000. Parallel developmental trends, involving increasing reliance on linear representations of numbers and decreasing reliance on logarithmic ones, emerged across different types of estimation. Consistent individual differences across tasks were also apparent, and all types of estimation skill were positively related to math achievement test scores. Implications for understanding of mathematics learning in general are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual differences in the responses of na?ve rhesus monkeys to snakes.

The authors demonstrated individual differences in inhibited behavior and withdrawal responses of laboratory-born rhesus monkeys when initially exposed to a snake. Most monkeys displayed a small significant increase in their behavioral inhibition in the presence of a snake. A few monkeys had marked responses, and some actively withdrew. Although the responses of the most extreme laboratory-born monkeys were comparable to feral-born monkeys, the responses of the laboratory-born monkeys rapidly habituated. The individual differences in the responses of naive monkeys likely reflect a continuum from orienting to wariness to fear. A neurobiological model is presented that addresses potential mechanisms underlying these individual differences, their relation to fear, and how they may predispose to phobia development.

Characteristics associated with real and made-up events: The effects of event valence, event elaboration, and individual differences.

In three studies, participants rated both real and made-up personal events on several different characteristics. These included meta-cognitive beliefs about the perceived realness and typicality of these events, imagery ratings of visual detail, and emotional ratings of intensity and feelings. Studies 1 and 2 explored the impact of event valence (pleasant versus unpleasant) on these characteristics, whereas Study 3 focused on the effects of event elaboration involving guided imagery and journaling techniques. All three studies also included consideration of individual difference factors that might either enhance or attenuate the ratings that were obtained. Both Studies 1 and 2 found that pleasant events (be they real or made-up), were viewed as more typical, and more likely to have happened and be true, than unpleasant events. This pattern of meta-cognitive judgments provided support for a general positivity hypothesis, which proposes that most individuals orient towards and emphasize pleasant rather than unpleasant life experience and events. In contrast, the imagery-related components of these events, such as visual details, location, and time, were much less sensitive to the manipulation of event valence. Strong imagery-related effects, however, were noted when events were elaborated in the final study. Furthermore, this event elaboration manipulation also resulted in heightened meta-cognitive judgments of typicality, likelihood of the event having happened, and of being true. Finally, across all three studies, a series of correlational analyses indicated that the individual difference factors did not have any systematic effect on any of the event characteristic ratings. However, when event valence was not specifically manipulated (in Study 3), depressed individuals spontaneously provided twice as many unpleasant personal events as nondepressed individuals. These findings were then discussed in terms of source-confusion issues regarding personal memory accuracy, as well as the further extension of a recent model of autobiographical memory to incorporate event properties such as valence and elaboration.

Determinants of individual differences and gender differences in knowledge.

The authors investigated the abilities, self-concept, personality, interest, motivational traits, and other determinants of knowledge across physical sciences/technology, biology/psychology, humanities, and civics domains. Tests and self-report measures were administered to 320 university freshmen. Crystallized intelligence was a better predictor than was fluid intelligence for most knowledge domains. Gender differences favoring men were found for most knowledge domains. Accounting for intelligence reduced the gender influence in predicting knowledge differences. Inclusion of notability predictors further reduced the variance accounted for by gender. Analysis of Advanced Placement test scores largely supported the results of the knowledge tests. Results are consistent with theoretical predictions that development of intellect as knowledge results from investment of cognitive resources, which, in turn, is affected by a small set of trait complexes.

Cross-cultural differences in the refusal to accept a small gift: The differential influence of reciprocity norms on Asians and North Americans.

Asians are more likely than North Americans to refuse a small gift that is offered to them by a casual acquaintance. Five experiments confirmed this difference and explored the reasons for its occurrence. Asians, who are inclined to think of themselves in relation to others, are more likely than North Americans to invoke a reciprocity norm in exchanging gifts with casual acquaintances, and they refuse a gift in order to avoid the feeling of indebtedness they would experience if they cannot reciprocate. North Americans, however, who are inclined to think of themselves independently of others, are more likely to base their acceptance of the gift on its attractiveness without considering their obligation to reciprocate. These cultural differences are not evident when the gift is offered by a close friend with whom individuals have a communal relationship. Implications of our findings for miscommunication between members of different cultures are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual differences in children's event memory reports and the narrative elaboration technique.

Children between 7 and 8 years old took pan in a staged event at school and 1 week later were assessed using a short form of the Wechsler Intelligence scale for children (third edition) and measures of metamemory, narrative ability, and socioeconomic status. Two weeks following the event, children either received narrative elaboration training (NET; K.J. Saywitz & L. Snyder, 1996) and were prompted with the four NET cue cards at interview; received verbal prompts corresponding to the cue card categories, but without prior training; or were presented with the cards at interview without prior training. Children given verbal labels as prompts recalled as much information as children who received NET training and cue cards. Measures of intelligence were predictive of amount recalled for cards-only children but not for the other 2 groups, indicating that differences in recall between low- and high-IQ groups were attenuated when recall was supported by NET training or verbal prompting.

Cross-cultural aging in cognitive and affective components of subjective well-being.

The present study examined age and cultural differences in cognitive and affective components of subjective well-being. A sample of 188 American and Chinese young and older adults completed surveys measuring self-life satisfaction, perceived family's life satisfaction, positive affect, and negative affect. Across cultures, older adults reported lower negative affect than did young adults. Americans reported higher self-life satisfaction, perceived family's life satisfaction, and positive affect than did Chinese. In addition, perceived family's life satisfaction was more related to self-life satisfaction for Chinese than for Americans. Findings are discussed in light of socioemotional selectivity theory and theories on culture and self-construal. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Will they stay or will they go? The role of job embeddedness in predicting turnover in individualistic and collectivistic cultures.

Although turnover is an issue of global concern, paradoxically there have been few studies of turnover across cultures. We investigated the cross-cultural generalizability of the job embeddedness model (Mitchell & Lee, 2001) by examining turnover in an individualistic country (United States) and a collectivistic country (India). Using cross-cultural data from call centers (N = 797), we demonstrated that although organization job embeddedness predicted turnover in both countries, different dimensions of job embeddedness predicted turnover in the United States and India. As hypothesized, on the basis of individualism–collectivism theory, person–job fit was a significant predictor of lower turnover in the United States, whereas person–organization fit, organization links, and community links were significant predictors of lower turnover in India. We also explored whether a newly developed construct of embeddedness—family embeddedness—predicts turnover above and beyond job embeddedness and found initial support for its utility in both the United States and India. Theoretical and practical implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Moral awareness and ethical predispositions: Investigating the role of individual differences in the recognition of moral issues.

The impact of the role of individual ethical predispositions, preferences for utilitarian and formalistic ideals, on managerial moral awareness was examined in 2 studies. Results suggested that a manager's ethical predispositions influence his or her responses to the characteristics of the moral issue. Both utilitarianism and formalism shaped moral awareness, but formalism demonstrated a greater capacity to do so in that formalists recognized both harm and the violation of a behavioral norm as indicators of the moral issue, whereas utilitarians responded only to harm. These findings provide support for the basic arguments underlying theories of moral development and offer several implications for the study and practice of moral awareness in organizations.

The association between psychopathology in fathers versus mothers and children's internalizing and externalizing behavior problems: A meta-analysis.

In light of the selective focus on maternal (vs. paternal) psychopathology as a risk factor for child development, this meta-analysis examines the relative strength of the association between psychopathology in mothers versus fathers and the presence of internalizing and externalizing disorders in children. Associations were stronger between maternal than paternal psychopathology and the presence of internalizing (but not externalizing) problems in children, with all average effect sizes being small in magnitude. Relations were moderated by variables that highlight theoretically relevant differences between psychopathology in mothers versus fathers (e.g., age of children studied, type of parental psychopathology) and by variables related to methodological differences across studies (e.g., method of assessing psychopathology in parents and children, type of sample recruited, familial composition).

Development of beliefs about the origins and controllability of dreams.

In three studies the authors investigated the development of beliefs about dreaming. Study 1 assessed 3 to 5-year-old children's beliefs about the origins and controllability of dreams. Results revealed significant changes in children's beliefs about the roles of behavioral experiences and mental processes in the generation of dream content. Results also revealed that young children consider both dreams and imagination to be highly controllable. In Study 2, preschool-age children, elementary school-age children, and adults received either imagination or dream stories and were questioned about controllability. In Study 3, emotional valence of the dream content was varied. Results of Studies 2 and 3 revealed significant development in beliefs that dreams are not subject to conscious control. Beliefs in controllability were higher among females. Study 3 showed that the emotional content of a dream affects these claims. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of assigned versus participatively set goals, knowledge of results, and individual differences on employee behavior when goal difficulty is held constant.

In Exp I, 60 female clerical workers were randomly assigned to participative, assigned, and "do best" goal conditions on a clerical test. Specific goals led to higher performance than did the "do best" goals. With goal difficulty held constant, there was no significant difference between the assigned and participative conditions on performance or goal acceptance. Goal attainment, however, was higher in the assigned condition than it was in the participative condition. No main or interaction effects were found for knowledge of results (KR) or for individual difference measures with performance or goal acceptance. However, high self-esteem Ss who received KR attained their goals more often than did Ss with low self-esteem when the goals were participatively set. Exp II was conducted with 28 employees from the same sample in a performance-appraisal setting over an 8-mo period. Assigned goals resulted in higher performance and greater goal acceptance than participatively set goals. There was a positive linear relationship between goal difficulty and performance in the participative condition only. (10 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
