The Disambiguation Prediction Effect

ABSTRACT

Children tend to select a novel object rather than a familiar object when asked to identify the referent of a novel label. Current accounts of this so-called disambiguation effect do not address whether children have a general metacognitive representation of this way of determining the reference of novel labels. In two experiments (each N = 48), three- and four-year-olds received a prediction task that required such a representation. In the initial phase, children completed four disambiguation test trials that were presented as instances of the same “game.” In the next phase, they received four additional trials. These differed only in that before the label was presented, children were asked to predict which object “was going to be right.” On the first prediction trial, most four-year-olds predicted the novel object, whereas most three-year-olds did not. On subsequent trials, despite having received feedback regarding predictions, three-year-olds showed no tendency to begin to predict the novel object, whereas most four-year-olds continued to make this prediction. These findings add to the evidence that most children develop a general metacognitive representation of their tendency to map novel labels onto novel rather than familiar objects some time around their fourth birthday.     

The social class worldviews of first-generation college students

The social class worldviews (social class beliefs, attitudes, and values) of 14 first-generation college students were investigated with qualitative interviews. Consensual qualitative research analysis revealed first-generation students’ perspectives on the development of their social class worldviews, the effect of these worldviews on their transitions to college, and vice versa. The students’ pre-college beliefs and values promoted hard work and college attendance as a means of financial success. The transition to college created disequilibrium in the social class worldviews of the students interviewed, who in turn responded by attempting to adapt to the new culture, emphasizing their social class background, or downplaying the role of social class in their lives altogether. College professionals working with first-generation students are encouraged to facilitate dialogues with first-generation students about their social class worldview and its impact on students’ engagement with the college community.     

The link between preschoolers' executive function and theory of mind and the role of epistemic states

The aim of this study was to assess the specific relation between 3- to 6-year-olds’ performance on a task measuring executive function (EF), the Dimensional Change Card Sort task (DCCS), and different developmental attainments in their theory of mind (ToM) by employing a battery of scaled ToM tasks that were comparable in task format and task demands. In addition, individual differences on the temperamental dimensions emotionality, activity, sociability, and shyness were assessed by parental rating. The main findings show that children’s (N = 195) performance on the DCCS related to their overall performance on the ToM scale but that this relation was specific to those ToM tasks that tap children’s understanding of epistemic states such as knowledge access, diverse beliefs, and false beliefs regarding content and location. The relation between children’s EF and overall ToM performance remained significant after controlling for age, sentence comprehension, child temperament, and parental education. Individual differences in child activity showed consistent negative relation to EF and ToM abilities. The findings point to a differential involvement of the various EF components in reasoning about different mental concepts.     

The influence of attachment and temperament on venipuncture distress in 14-month-old infants: the Generation R Study

Objective

This study examined the effects of attachment and temperament on infant distress during venipuncture.

Method

The study was embedded in the Generation R Study, a prospective population-based study. Two different research procedures (i.e., blood sampling and the Ainsworth Strange Situation Procedure) yielded measures of venipuncture distress and attachment security and disorganization in 246 infants aged 14 months. Four temperament traits (distress to limitations, fear, recovery from distress, and sadness) were assessed using the maternally reported Infant Behavior Questionnaire - Revised, at the age of 6 months.

Results

There were no differences between mean levels of distress during venipuncture in infants classified as having insecure attachment, but there was a trend for disorganized attachment. The temperament traits were not related to distress. However, children with a disorganized attachment and higher temperamental fear had more venipuncture distress.

Conclusion

When different risk factors are present simultaneously, infant distress is heightened.     

Establishing the next generation at work: leader generativity as a moderator of the relationships between leader age, leader-member exchange, and leadership success

In this study, the authors investigated leader generativity as a moderator of the relationships between leader age, leader-member exchange, and three criteria of leadership success (follower perceptions of leader effectiveness, follower satisfaction with leader, and follower extra effort). Data came from 128 university professors paired with one research assistant each. Results showed positive relationships between leader age and leader generativity, and negative relationships between leader age and follower perceptions of leader effectiveness and follower extra effort. Consistent with expectations based on leadership categorization theory, leader generativity moderated the relationships between leader age and all three criteria of leadership success, such that leaders high in generativity were better able to maintain high levels of leadership success at higher ages than leaders low in generativity. Finally, results of mediated moderation analyses showed that leader-member exchange quality mediated these moderating effects. The findings suggest that, in combination, leader age and the age-related construct of generativity importantly influence leadership processes and outcomes.     

Phantom Behavioral Assimilation Effects: Systematic Biases in Social Comparison Choice Studies

ABSTRACT Consistent with social comparison theory (SCT), Blanton, Buunk, Gibbons, and Kuyper (1999) and Huguet, Dumas, Monteil, and Genestoux (2001) found that students tended to choose comparison targets who slightly outperformed them (i.e., upward comparison choices), and this had a beneficial effect on subsequent performance—a behavioral assimilation effect (BAE). We show (Studies 1 and 2) that this apparent BAE is due, in part, to uncontrolled measurement error in pretest achievement. However, using simulated data (Study 3), these phantom BAEs were eliminated with latent‐variable models with multiple indicators. In Studies 4 and 5, latent‐variable models were applied to the Blanton et al. and Huguet et al. data, resulting in substantially smaller but still significantly positive BAEs. More generally in personality research based on correlational data, failure to control measurement error in pretest/background variables will positively bias the apparent effects of personality variables of interest, but widely applicable approaches demonstrated here can correct for these biases.     

National Origin and Behavioural Problems of Toddlers: The Role of Family Risk Factors and Maternal Immigration Characteristics

In many societies the prevalence of behavioural problems in school-aged children varies by national origin. We examined the association between national origin and behavioural problems in 1½-year-old children. Data on maternal national origin and the Child Behavior Checklist for toddlers (n?=?4943) from a population-based cohort in the Netherlands were used. Children from various non-Dutch backgrounds all had a significantly higher mean behavioural problem score. After adjustment for family risk factors, like family income and maternal psychopathology, the differences attenuated, but remained statistically significant. Non-Dutch mothers with immigration risk factors, such as older age at immigration or no good Dutch language skills, reported significantly more behavioural problems in their offspring. In conclusion, the present study indicated more behavioural problems in immigrant toddlers from various backgrounds. Researchers and policymakers aiming to tackle disparities in behavioural problems should take into account that risks associated with national origin are intertwined with unfavourable family and immigration characteristics.     

Dynamics of Friendship Reciprocity Among Professional Adults

Friendship is generally a reciprocal relation, yet many enduring ties are not symmetrical. Sometimes, only one member of a dyad considers the other a friend, or may see their relation as a close friendship while the other does not. Existing theories imply that personal and social attributes may influence the likelihood of reciprocity in friendship. In this longitudinal study, we found that demographic and educational attributes had little effect, but relative gregariousness and popularity consistently influenced development and persistence of unequally reciprocated friendships in 2 cohorts of executive MBA students. Additionally, higher gatekeeping power predicted greater tendency to befriend members of different age categories. Although gatekeeping power correlated directly with unequal reciprocity, the effect was mediated by gregariousness and popularity.
