This study explores dynamic processes in the development of the psychological contract, focusing on the interaction of obligations related to the two parties (i.e., employees' perceptions of both their own and the organization's obligations fulfillment) on attitudinal outcomes (organizational commitment and turnover intention) during the initial stage of the employment relationship.

Secure attachment relationships have been described as having a regulatory function in regard to children's emotions, social cognition, and behavior. Although some theorists and researchers have argued that attachment affects children's self-regulation. most attachment theorists have not strongly emphasized this association. The goal of the current meta-analysis was to determine the magnitude of the relation between attachment security status and effortful control (EC)/top-down self-regulation in children up to 18 years of age.

During adolescence, some personality characteristics may represent vulnerabilities to adolescents' adjustment. Adopting a person-centered approach, the aims of this study were (a) to examine the relations of early adolescents' personality profiles to internalizing (i.e., anxious/depressed, withdrawal, and somatic complaints) and externalizing (i.e., aggressive and rule breaking behavior) problems three years later, and (b) to explore the moderating role of gender in these relations.

The study examined whether developmental deficits in reading and numerical skills could be expressed in terms of global factors by reference to the rate and amount (RAM) and difference engine (DEM) models. From a sample of 325 fifth grade children, we identified 5 children with dyslexia, 16 with dyscalculia, 7 with a “mixed pattern,” and 49 control children.

Objective: The Bells Test is a cancelation task that is widely used for the diagnosis of unilateral spatial neglect (USN). With the aim of fostering more reliable use of this instrument, we set out to develop new norms adjusted for the possible influence of age, gender and education. We worked on the original version of the test. Methods: Normative data were collected from 401 healthy participants aged between 20 and 80 years. Individual factors that could affect performance (i.e., gender, age, and years of education) were considered.

Visual working memory exhibits age effects that are amongst the largest observed in the cognitive aging literature. In this research we investigated whether or not older adults can benefit from visual symmetry and semantic availability, as young adults typically do. Visual matrix pattern tasks varied in terms of the perceptual factor of symmetry (Experiment 1), as well as the availability of visual semantics, or long-term memory (LTM; Experiment 2).

Researchers interested in the study of implicit (and, to a lesser degree, explicit) memory have frequently used word stem completion (WSC) to measure repetition priming in both healthy and clinical populations. In this task, participants are asked to complete each of several stems (e.g., ele__) with the first word that comes to mind (e.g., elephant). A key problem, however, is that the baseline completion rates of the stems corresponding to the target words must be known in advance, if the researcher want to maximize the possibility to detect sizable priming effects.

Several studies have demonstrated that the processing of visuospatial memory for locations in reaching space and in navigational space is supported by independent systems, and that the coding of visuospatial information depends on the modality of the presentation (i.e., sequential or simultaneous). However, these lines of evidence and the most common neuropsychological tests used by clinicians to investigate visuospatial memory have several limitations (e.g., they are unable to analyze all the subcomponents of this function and are not directly comparable).

Trait Emotional Intelligence (or trait emotional self-efficacy) is a constellation of emotional perceptions assessed through questionnaires and rating scales (Petrides et al., 2007b). This paper examined the psychometric features of the Trait Emotional Questionnaire Full Form (TEIQue-FF; Petrides, 2009b) in the Italian context. Incremental validity in the prediction of depression and anxiety was also tested with respect to the Big Five. Participants were 1343 individuals balanced for gender (690 females and 653 males) whose mean age was 29.65 years (SD = 13.64, range 17-74 years).

The detrimental effects of job insecurity are well recognized in the scientific literature. In this paper, we investigate the impact of qualitative job insecurity on an outcome that has been somewhat neglected to date: organizational identification. In addition, we test the moderating role of organizational justice in the relationship between qualitative job insecurity and organizational identification. A group of 170 workers completed a questionnaire assessing qualitative job insecurity, overall organizational justice, and identification with the organization.
