Can you get a better deal elsewhere? The effects of psychological contract replicability on organizational commitment over time

Previous research on psychological contracts has focused on whether or not employees feel their employers have fulfilled the promises made to them. Instead, here we examine how perceptions of the external labor market, particularly about whether present psychological contracts could be replicated elsewhere, influence employees’ attachment to their current employers. In a longitudinal study of a diverse employee sample, we found perceptions that psychological contracts could not be replicated elsewhere accounted for a substantial amount of the variance in affective commitment (.38) and normative commitment (.29) and a smaller, but significant, amount of the variance in continuance commitment (.04). We also found significant moderating effects of age, work experience, and career stage on these relationships. The article concludes with implications for psychological contract theory, organizational commitment theory, and management practice.     

A cognitive cascade in infancy: Pathways from prematurity to later mental development

Using data from a longitudinal study of preterms and full-terms, the present study examined the structure of infant cognition at 12 months, the extent to which five 12-month abilities (attention, processing speed, recognition, recall, and representational competence) mediated the relation from prematurity to mental development at 2–3 years, and how continuity and change in infant information processing from 7 to 12 months affected later outcome. The results indicated that 12-month measures of infant information processing completely mediated the effect of prematurity on outcome and the infant measures form a ‘cognitive cascade’, similar to that seen at 7 months, in which the two more elementary abilities (attention and speed) influenced the more complex ones, which in turn influenced later cognition. Additionally, despite cross-age stability, 7-month assessments contribute to outcome independently of their 12-month counterparts, suggesting that infant abilities undergo important developmental transformations in the second half of the first year of life.     

The inversion effect in infancy: the role of internal and external features

The present work examined the changing role of inner and outer facial features in the recognition of upright and inverted faces in 5-, 7-, and 9-month-olds. Study 1 established that the “inversion effect” (impaired recognition of an inverted face) was present in infants as young as 5 months. In Study 2, internal and external features were inverted separately. Disrupting the internal configuration by inversion impaired recognition at all ages; disrupting the external configuration impaired recognition only at 5-months. In Study 3, an upright familiar face was paired with one having either novel internal or novel external features. The results confirmed that the 5-month-olds used only the external features to recognize faces, whereas older infants were as adept at using internal features as external ones. These findings suggest a shift, after 5 months, away from dependence on external features for face recognition and toward greater reliance on internal ones.     

List context fosters semantic processing: parallels between semantic and morphological facilitation when primes are forward masked

The authors examined patterns of facilitation under forward-masked priming conditions across 3 list contexts (Experiments 1-3) that varied with respect to properties of filler trials -- (a) mixed (morphological, orthographic, semantic), (b) identity, and (c) semantic -- but held the relatedness proportion constant (75%). Facilitation for targets that were related morphologically to their prime occurred regardless of filler context, but facilitation for semantically related pairs occurred only in the context of identity and semantic fillers. Facilitation was absent for orthographically similar prime-target pairs in all 3 filler contexts when matching numbers of orthographically similar word-word and word-nonword prime-target pairs rendered orthographic similarity uninformative with respect to lexicality of the target. Enhanced semantic and morphological facilitation in the context of identity and semantic relative to mixed fillers support a semantically attuned, as contrasted with a purely form-based, account of early morphological processing.     

A rational analysis of rule-based concept learning

This article proposes a new model of human concept learning that provides a rational analysis of learning feature-based concepts. This model is built upon Bayesian inference for a grammatically structured hypothesis space—a concept language of logical rules. This article compares the model predictions to human generalization judgments in several well-known category learning experiments, and finds good agreement for both average and individual participant generalizations. This article further investigates judgments for a broad set of 7-feature concepts—a more natural setting in several ways—and again finds that the model explains human performance.     

Goal orientation dispositions and performance trajectories: The roles of supplementary and complementary situational inducements

Integrating goal orientation theory with interactionist approaches, this experimental study (N = 104) tested the unique and interactive effects of individual differences in goal orientations and situational goal orientation inducements on performance trajectories during skill acquisition. Results indicated that learning goal orientation predicted performance trajectories more positively when coupled with one situational inducement that captures a complementary feature (a performance, as opposed to a learning, goal frame), and when jointed with a situational inducement that captures a supplementary feature (self-referenced vs. normative-based performance feedback). There was also a complementary-like interaction between the two situational inducements, such that a learning goal frame led to more positive performance trajectories when coupled with normative, as opposed to self-referent, feedback. Implications for the motivation and skill acquisition literatures are discussed.     

Grandparents as family stabilizers during economic hardship in Bulgaria

T he present study of three generations' families living together during a period of marked economic dislocation investigates whether supportive grandparents can ameliorate the negative effects of economic stress on parenting and on teen outcomes. The study focuses on harsh parenting and adolescent depression, which has been shown to be especially responsive to economic stress. Three hypotheses were investigated: (1) in extended families there is a link between economic adversity and adolescent depression that is mediated by harsh parenting; (2) grandparent support diminishes the relationship between economic pressure and harsh parenting; and (3) grandparent support diminishes the relationship between harsh parenting and adolescent depression. Data were collected from a community sample of 62 extended families with an adolescent during a period of marked economic dislocation in Bulgaria. Mothers, fathers, and adolescents completed questionnaires about perceived economic pressure, parents' harsh parenting, and perceived support of grandparents. Adolescents also completed a measure of self‐reported depression. Additional interviews were conducted with every eligible family member about family relations. Results showed that even though there was significant economic stress reported by parents, adolescents reported moderate levels of depression and low levels of harsh parenting by mothers and fathers. Correlation and regression analyses revealed that whenever respondents experienced support by grandparents, it made a difference for family members. More specifically, despite economic stress, mothers who experienced the support of grandparents tended to exercise less harsh parenting practices than mothers who lacked such support. Furthermore, when grandparents were supportive, harsh parenting was not associated with adolescent depression. These findings are discussed in the light of existing studies of families under economic pressure with a special focus on extended family relations and the role of cultural context.
