Political skill as neutralizer of felt accountability—job tension effects on job performance ratings: A longitudinal investigation

This study examined the effects of felt accountability, political skill, and job tension on job performance ratings. Specifically, we hypothesized that felt accountability would lead to higher (lower) job performance ratings when coupled with high (low) levels of political skill, and that these relationships would be mediated by job tension. Data were gathered at multiple times over a one-year period (i.e., baseline performance, attitudinal variables one month later, supervisor reports of subordinate performance six months and one year after baseline performance was measured). Strong support was shown for the total effects model, whereby political skill moderated felt accountability—job performance ratings, felt accountability—job tension, and job tension—job performance ratings relationships. However, more focused analyses demonstrated that political skill most strongly moderated the job tension—job performance ratings linkage. Implications, strengths and limitations, and directions for future research are provided.     

Using selection,optimization, and compensation to reduce job/family stressors: effective when it matters

Previous research has demonstrated that the use of general behaviors specified by a life-management strategy entitled Selection, Optimization, and Compensation (SOC) reduces, if only to a small extent, the perceived amounts of the main antecedents (i.e., job/family stressors) of work-family conflict. The results of the current study demonstrate that several variables that impact the amount of resources demanded of, or resources available to, an individual (e.g., supervisor support) moderate the relationship between SOC behaviors and job/family stressors. Specifically, SOC strategies are more effective than previously thought at reducing job/family stressors for precisely those individuals in the most demanding situations.     

Language outcome after perinatal stroke: does side matter?

The goal of this study was to examine structured language skills in children with perinatal strokes. Participants were 28 school-age children with early focal brain lesions (17 with left hemisphere [LH] damage, 11 with right hemisphere [RH] damage), and 57 controls. A standardized test of language (Clinical Evaluation of Language Fundamentals-Revised) was administered. Receptive, Expressive, and Total Language scores, as well as subtest scores, were analyzed. Control participants scored within the normal range, whereas the LH and RH groups scored significantly more poorly than did controls. There were no differences between the LH and RH groups on any of the language scores, and all scores were below the 14th percentile. Within the lesion group as a whole, scores were not related to lesion laterality, site, or severity. Results also were not accounted for by socioeconomic status or IQ. However, children who experienced seizures demonstrated significantly poorer performance than did children who did not experience seizures. Damage to either the LH or RH early in development adversely affects later language abilities, particularly on tasks with structured and complex linguistic demands. Although lesion side has little effect, the presence or absence of seizures is a major contributor to language outcome.     

Relationship between object-related gestures and the fractionated object knowledge system

The praxic semantic system comprises a conceptual knowledge system, which stores functional information about objects, and an action knowledge system, which stores information about the correct manipulation of objects. Moreover, mechanical problem solving abilities permit to take advantages from objects structure to use unfamiliar tools or discover alternative ways of using familiar tools. This study aims at investigating whether conceptual knowledge, action knowledge and mechanical problem solving abilities intervene in the production of gestures with objects (i.e. pantomimes and object use) by testing a group of brain damaged patients. Results showed that the mechanical problem solving abilities are not sufficient to produce pantomimes and that only severe deficits in the praxic semantic system would affect the production of these gestures. Furthermore, a double dissociation was observed between mechanical problem solving abilities and the capacity to use multiple objects. Overall, the results indicate that the praxic semantic system can be disrupted at different levels, suggesting that the semantic system for object has to be conceived as fractionated in different entities.     

Age-related differences in immediate serial recall: Dissociating chunk formation and capacity

We assessed the contribution of two hypothesized mechanisms to impaired memory performance of older adults in an immediate serial recall task: decreased temporary information storage in a capacity-limited mechanism, such as the focus of attention, and a deficit in binding together different components into cohesive chunks. Using a method in which paired associations between words were taught at varying levels to allow an identification of multiword chunks (Cowan, Chen, & Rouder, 2004), we found that older adults recalled considerably fewer chunks and, on average, smaller chunks than did young adults. Their performance was fairly well simulated by dividing attention in younger adults, unlike what has been found for long-term associative learning. Paired-associate knowledge may be used in an implicit manner in serial recall, given that younger adults under divided attention and older adults use it well despite the relatively small chunk capacities displayed by these groups.     

Reversing the picture superiority effect: A speed—accuracy trade-off study of recognition memory

Speed-accuracy trade-off methods have been used to contrast single- and dual-process accounts of recognition memory. With these procedures, subjects are presented with individual test items and required to make recognition decisions under various time constraints. In three experiments, we presented words and pictures to be intentionally learned; test stimuli were always visually presented words. At test, we manipulated the interval between the presentation of each test stimulus and that of a response signal, thus controlling the amount of time available to retrieve target information. The standard picture superiority effect was significant in long response deadline conditions (i.e., > or = 2,000 msec). Conversely, a significant reverse picture superiority effect emerged at short response-signal deadlines (< 200 msec). The results are congruent with views suggesting that both fast familiarity and slower recollection processes contribute to recognition memory. Alternative accounts are also discussed.     

A preliminary examination of the intergenerational continuity of maternal psychopathic features

The study provided a preliminary test of the intergenerational continuity of maternal psychopathic features in a non-referred elementary aged sample of children. Consistent with dominant etiological models and recent behavioral genetics research, a direct association was expected between maternal and child affective features of psychopathy (i.e., callous-unemotional or CU traits). Potential mediators representative of alternative transmission mechanisms were assessed including parenting dysfunction, parental hostility/interpersonal insensitivity, and child impulsivity. Behavioral features of psychopathy were also assessed and were predicted to bear weaker and more indirect parent-child associations. A mixed sex sample of 83 children accompanied by a biological mother were administered a multi-informant rating-scale battery including separate parent (i.e., Levenson Self-Report Psychopathy Scale) and child (i.e., Antisocial Process Screening Device) measures of psychopathy. Consistent with prediction, a significant association was documented between maternal and child CU traits (r=.22). Additionally, a slightly weaker association and statistical trend (r=.21) was observed in the relation between maternal and child interpersonal features of the psychopathy construct. Contrary to prediction, all documented associations were fully mediated by parental hostility and parenting dysfunction. Given the preliminary nature of study findings, implications for developmental modeling and future intergenerational continuity research are discussed.     

Individual differences in components of reaction time distributions and their relations to working memory and intelligence

The authors bring together approaches from cognitive and individual differences psychology to model characteristics of reaction time distributions beyond measures of central tendency. Ex-Gaussian distributions and a diffusion model approach are used to describe individuals' reaction time data. The authors identified common latent factors for each of the 3 ex-Gaussian parameters and for 3 parameters central to the diffusion model using structural equation modeling for a battery of choice reaction tasks. These factors had differential relations to criterion constructs. Parameters reflecting the tail of the distribution (i.e., tau in the ex-Gaussian and drift rate in the diffusion model) were the strongest unique predictors of working memory, reasoning, and psychometric speed. Theories of controlled attention and binding are discussed as potential theoretical explanations.     

Influence of vocal cues on learning about objects in joint attention contexts

An experimenter taught infants about a novel toy in two joint attention conditions, one with and one without vocal cues. In test trials, infants viewed the familiar toy and a novel toy. Infants in the Joint Attention plus Voice condition looked significantly longer to the novel toy.     

The Price of Rights: High School Students' Civic Values and Behaviors

Previous analyses of U.S. civics textbooks documented an overwhelming emphasis on citizen rights to the relative exclusion of citizen obligations and participation. Despite evidence of this uneven coverage, scholars have not yet investigated the psychological and behavioral consequences of this asymmetry, which may be especially consequential in the U.S., a predominantly individualistic culture. The present research does just this by analyzing survey data collected from high school students in civics courses. As expected, and in accordance with the content of civics curricula, students show greater endorsement of rights than of obligations. Moreover, higher support for obligations increases students' intention to vote and to participate in civic and extracurricular activities, whereas endorsement of rights is negatively associated with political participation.
