Deadly combinations: how leadership contexts undermine the activation and enactment of followers’ high core self-evaluations in performance

Employees with high core self-evaluations (CSE) generally perform well in their jobs. The enactment of CSE in performance occurs within contexts, and leadership is one form of context that influences the activation and expression of CSE. Drawing on theories of CSE and leader–member exchange (LMX), we characterized the leadership context as the interaction between leader CSE and LMX quality. Examination of 173 followers and their 31 leaders in a manufacturing organization showed a positive association between follower CSE and performance when the context comprised high leader CSE and high LMX. Conversely, leadership contexts comprising high leader CSE and low LMX, or low leader CSE and high LMX, resulted in a negative relationship between follower CSE and performance. We also show that low CSE followers have relatively high performance under some circumstances. Thus, we contribute to understanding how some leadership contexts undermine high CSE followers’ performance and promote low CSE followers’ performance.     

Electrophysiological evidence for late maturation of strategic episodic retrieval processes

Improvement in source memory performance throughout development is thought to be mediated by strategic processes that facilitate the retrieval of task-relevant information. Using event-related potentials (ERPs), we examined developmental changes in these processes during adolescence. Adolescents (13-14 years) and adults (19-29 years) completed a memory exclusion task which required the discrimination between words studied in one color ('targets') and words studied in the alternative color ('non-targets') under two conditions that put different demands on strategic control. Memory accuracy improved with age and also increased with decreasing control demands in both age groups. The parietal old/new effect, an ERP correlate of recollection, was reliable for targets across conditions in both age groups. By contrast, ERP correlates of non-target recollection were present in adolescents across conditions but not in adults. This suggests that adults implemented a strategy to prioritize recollection of target information with greater success than adolescents regardless of control demands, presumably reflecting maturational differences in cognitive control. In support of this view, the ERP amplitude difference between targets and non-targets was positively correlated with a measure of working memory capacity (WMC) in adults but not in adolescents. A further age-related difference was that ERP correlates of post-retrieval processing, including late right-frontal old/new effects and late posterior negativities, were observed in adults only. Together, our data suggest protracted maturation in the strategic processes that underlie selective recollection and post-retrieval control.     

Coping variables as predictors of perioperative emotional states and adjustment

Abstract

Surgery, regardless of its kind and severity, can be regarded as a major stress situation for any patient. High preoperative emotional arousal may negatively influence adaptation during surgery and, consequently, rate of postoperative recovery. In a series of previous studies, our research group analyzed the influence of dispositional and actual coping on subjective and objective stress indicators before, during, and after surgery. The present study investigates the influence of the dispositional coping variables vigilance and cognitive avoidance on actual surgery-related coping, state anxiety, and indicators of intra- and postoperative adjustment. The sample consisted of 42 male and 42 female patients undergoing elective maxillofacial surgery under general anaesthesia. Dispositional coping was measured on the dimensions vigilance and cognitive avoidance with the Mainz Coping Inventory. Actual surgery-related coping was assessed by means of a newly constructed inventory containing items to measure the four dimensions avoidance, vigilance, positive restructuring, and seeking social support.

Self-reported state anxiety was differentiated according to the cognitive, affective, and somatic components. The patients' adaptation was assessed by measuring doses of the narcotic agents used for induction of anaesthesia, the intraoperative status, and the amount of postoperative (analgesic and psychotropic) medication. Significant effects of coping mode, gender, and time of measurement were observed on the cognitive, affective and somatic component of state anxiety, the indicators of intraoperative adaptation and on postoperative medication. Also, patients' actual coping behavior could partly be predicted by dispositional coping. Results indicate that actual coping behavior and gender should be taken into account when trying to predict adaptation and developing psychological preparatory intervention programs.     

Health problems and quitting among female "temps"

The current study focused how individual contract preference among female agency "temps" was related to perceptions of the job, and to somatic complaints and distress and quitting. The effort reward model by (Siegrist, 1996) was used as a general, theoretical framework guiding the choice of relevant job features. The mediating role of job perceptions on the relationship between contract preference and the outcomes was tested, controlling for several possible confounding factors. Data came from questionnaires, answered by 227 female employees, together with records of turnover provided by the employing agency. Results supported a model where contract preferences appeared to be negatively related to both health outcomes, and the relation was mediated by perceptions of work load and social support. Contract preferences were strongly related to intentions to quit, but not to actually leaving the job within 6 months.     

Discrimination of human and dog faces and inversion responses in domestic dogs (Canis familiaris)

Although domestic dogs can respond to many facial cues displayed by other dogs and humans, it remains unclear whether they can differentiate individual dogs or humans based on facial cues alone and, if so, whether they would demonstrate the face inversion effect, a behavioural hallmark commonly used in primates to differentiate face processing from object processing. In this study, we first established the applicability of the visual paired comparison (VPC or preferential looking) procedure for dogs using a simple object discrimination task with 2D pictures. The animals demonstrated a clear looking preference for novel objects when simultaneously presented with prior-exposed familiar objects. We then adopted this VPC procedure to assess their face discrimination and inversion responses. Dogs showed a deviation from random behaviour, indicating discrimination capability when inspecting upright dog faces, human faces and object images; but the pattern of viewing preference was dependent upon image category. They directed longer viewing time at novel (vs. familiar) human faces and objects, but not at dog faces, instead, a longer viewing time at familiar (vs. novel) dog faces was observed. No significant looking preference was detected for inverted images regardless of image category. Our results indicate that domestic dogs can use facial cues alone to differentiate individual dogs and humans and that they exhibit a non-specific inversion response. In addition, the discrimination response by dogs of human and dog faces appears to differ with the type of face involved.     

Race differences in psychopathology and disparities in treatment seeking: Community and jail-based treatment seeking patterns

Whites in community samples utilize mental health services at a much higher rate than African Americans (Kessler, et al., 2005). Is this also the case among those in jails? In this study of jail inmates (229 African American, 185 White) there were no race difference in the overall need for mental health treatment (63% of participants had significant symptoms on the Personality Assessment Inventory) but race differences in the level and types of symptoms were evident. Additionally, while Whites were more likely to report pre-incarceration treatment there were no differences in treatment seeking or access to mental health programs while in jail, implying that if barriers to treatment in the community were removed (cost/insurance, location/transportation, time) racial disparities in treatment utilization may be reduced.     

Switching between filter settings reduces the efficient utilization of visual working memory

The capacity limitation of working memory requires that only relevant information gains access to the workspace, while irrelevant information is kept out. Thus, the ability to use attention to filter out irrelevant information is an important factor in how efficiently the limited storage space is used. Here, we examined to what degree the requirement to flexibly change filter settings affects filtering efficiency. Participants were presented with visual objects in different colors, and a cue presented in advance indicated which objects had to be stored. The contralateral delay activity, an event-related brain potential that reflects working-memory load was used to assess filtering efficiency during the retention interval. The data of two experiments showed that when filter settings had to be adjusted on a trial-by-trial basis, more irrelevant information passed the gate to working memory. Moreover, this switching-induced filtering deficit was restricted to those items that matched the previous, but currently irrelevant, filter settings. Thus, lingering effects of the selection history seem to counteract goal-directed encoding, and thus constitute an important attentional limitation for the efficient utilization of our limited workspace.     

Early processing of emotional faces in children with autism: An event-related potential study

Social deficits are one of the most striking manifestations of autism spectrum disorders (ASDs). Among these social deficits, the recognition and understanding of emotional facial expressions has been widely reported to be affected in ASDs. We investigated emotional face processing in children with and without autism using event-related potentials (ERPs). High-functioning children with autism (n = 15, mean age = 10.5 ± 3.3 years) completed an implicit emotional task while visual ERPs were recorded. Two groups of typically developing children (chronological age-matched and verbal equivalent age-matched [both ns = 15, mean age = 7.7 ± 3.8 years]) also participated in this study. The early ERP responses to faces (P1 and N170) were delayed, and the P1 was smaller in children with autism than in typically developing children of the same chronological age, revealing that the first stages of emotional face processing are affected in autism. However, when matched by verbal equivalent age, only P1 amplitude remained affected in autism. Our results suggest that the emotional and facial processing difficulties in autism could start from atypicalities in visual perceptual processes involving rapid feedback to primary visual areas and subsequent holistic processing.     

Trait anger moderates the impact of anger-associated rumination on social well-being

In this study, we examined whether people’s social well-being is influenced by hostile versus nonhostile goals that people report pursuing when experiencing anger-associated rumination. Moreover, we investigated the impact of trait anger and trait anger rumination on the relationship between anger rumination and perceived social well-being. Participants were 93 students who were equipped with hand-held computers for 28 days to assess anger-related rumination and its social consequences in daily life. Results showed that hostile goal pursuit per se did not affect perceived social well-being. However, impairment of social well-being following hostile rumination was moderated by trait anger. Findings are consistent with recent cognitive models of trait anger and anger rumination.
