Does positive team mood mediate the relationship between team climate and team performance?

We tested whether the relationship between a team climate of support from the organization and team performance is mediated by positive team mood. Recent research has shown that this team climate facet is related to team performance, but we do not have any empirical evidence about the mechanisms involved in this relationship. The study sample was composed of 59 bank branches, and a longitudinal design with three data-collection points was implemented. The results showed that a team climate of support from the organization was positively related to positive team mood, which in turn was positively related to team members' ratings of team performance.     

Recognition memory deficits in mild cognitive impairment

ABSTRACT There is no agreement on the pattern of recognition memory deficits characteristic of patients diagnosed with mild cognitive impairment (MCI). Whereas lower performance in recollection is the hallmark of MCI, there is a strong controversy about possible deficits in familiarity estimates when using recognition memory tasks. The aim of this research is to shed light on the pattern of responding in recollection and familiarity in MCI. Five groups of participants were tested. The main participant samples were those formed by two MCI groups differing in age and an Alzheimer's disease group (AD), which were compared with two control groups. Whereas one of the control groups served to assess the performance of the MCI and AD people, the other one, composed of young healthy participants, served the purpose of evaluating the adequacy of the experimental tasks used in the evaluation of the different components of recognition memory. We used an associative recognition task as a direct index of recollection and a choice task on a pair of stimuli, one of which was perceptually similar to those studied in the associative recognition phase, as an index of familiarity. Our results indicate that recollection decreases with age and neurological status, and familiarity remains stable in the elderly control sample but it is deficient in MCI. This research shows that a unique encoding situation generated deficits in recollective and familiarity mechanisms in mild cognitive impaired individuals, providing evidence for the existence of deficits in both retrieval processes in recognition memory in a MCI stage.     

Does role stress predict burnout over time among health care professionals?

Abstract

The main objective of this study is to test the effects over time of three role stress variables (role conflict, role ambiguity and role overload) on the three burnout dimensions (emotional exhaustion, depersonalization and personal accomplishment). Based on theoretical models on burnout and on meta-analytical research, it is hypothesized that the three role stress variables will predict changes over time in emotional exhaustion and depersonalization, but not in personal accomplishment. The results obtained by means of hierarchical regression analysis partially support the hypothesis. The three role stress variables predict emotional exhaustion over time. Role conflict and role overload predict depersonalization over time. Finally, contrary to expectations, role ambiguity predicts personal accomplishment over time.     

Organizational justice and extrarole customer service: The mediating role of well-being at work

The purpose of this article is to propose and test a model of extrarole customer service (ERCS). We propose that organizational justice (distributive, procedural, interpersonal, and informational) promotes well-being at work (low burnout and high engagement). Well-being at work, in turn, engenders more effective ERCS. Thus, well-being at work is considered a mediator of the relationships from organizational justice to ERCS. This fully mediated model was compared to an alternative fully direct model. The sample consisted of 317 contact employees who were working in the Spanish service sector. The results of structural equation modelling supported the importance of the mediating role of the positive side of well-being at work (engagement) in the relationship between organizational justice and ERCS. The article concludes with a discussion of the theoretical and managerial implications.     

Functional Mobility in a Divided Attention Task in Older Adults With Cognitive Impairment

ABSTRACT. Motor disorders may occur in mild cognitive impairment (MCI) and at early stages of Alzheimer's disease (AD), particularly under divided attention conditions. We examined functional mobility in 104 older adults (42 with MCI, 26 with mild AD, and 36 cognitively healthy) using the Timed Up and Go test (TUG) under 4 experimental conditions: TUG single task, TUG plus a cognitive task, TUG plus a manual task, and TUG plus a cognitive and a manual task. Statistically significant differences in mean time of execution were found in all four experimental conditions when comparing MCI and controls (p < .001), and when comparing MCI and AD patients (p < .05). Receiver-operating characteristic curve analyses showed that all four testing conditions could differentiate the three groups (area under the curve > .8, p < .001 for MCI vs. controls; area under the curve > .7, p < .001 for MCI vs. AD). The authors conclude that functional motor deficits occurring in MCI can be assessed by the TUG test, in single or dual task modality.     

Is it possible to be too happy? Happiness,personality, and psychopathology

The types of relationship between happiness, personality and psychopatholgy are assessed in an available sample (n = 321, adults, both sexes). Empirical results from two happiness scales and two questionnaires, one of personality (NEO-PI-R) and other of personality disorders (Loranger's scale), do not confirm the Diener's threshold hypothesis, that makes a distinction between optimum and maximum happiness; or the Seligman's supposition, that assumes that happiness has no limits; The main results are: a) negative affect (Neuroticism) is negatively related to happiness across its full range; b) Extraversion and Openness to experience are positively related to happiness across its full range; c) in the rest of the basic personality factors, relationships are not linear, though not in the sense anticipated by Diener, and d) in personality disorders, the tendencies observed diversify according to the type of disorder, and the type of happiness factor. On most occasions, the close relationship between personality disorders and the Neuroticism dimension is verified in a consistent manner. These results are discussed within the context of clinical psychology, and the general theory about happiness.     

When managers and their teams disagree: a longitudinal look at the consequences of differences in perceptions of organizational support

The authors argue that over time the difference between team members' perception of the organizational support received by the team (or team climate for organizational support) and their manager's perception of the organizational support received by the team has an effect on important outcomes and emergent states, such as team performance and team positive and negative affect above and beyond the main effects of climate perceptions themselves. With a longitudinal sample of 179 teams at Time 1 and 154 teams at Time 2, the authors tested their predictions using a combined polynomial regression and response surface analyses approach. The results supported the authors' predictions. When team managers and team members' perceptions of organizational support were high and in agreement, outcomes were maximized. When team managers and team members disagreed, team negative affect increased and team performance and team positive affect decreased. The negative effects of disagreement were most amplified when managers perceived that the team received higher levels of support than did the team itself.     

Facilitation of the equivalence--equivalence responding

Equivalence-Equivalence responding, based on equivalence class formation, is a key concept of the functional-analytic model of analogical reasoning held by RFT theorists. Relational stimulus control is supposed to play an important role in this arbitrary relational response. Previous research showed that mere training of the prerequisites for equivalence class formation is not always enough for the derivation of equivalence-equivalence responding, even in adults. In the first experiment, with 12 adult participants, we designed a matching-to-sample training and testing procedure that, although it provided all necessary conditions, did not lead to Equivalence-Equivalence responding in most participants, so that the efficacy of a facilitation procedure could be assessed. In Experiment 2, with 32 valid participants, a matching-to-sample procedure based on non-arbitrary relations was introduced to assess its efficacy in enhancing stimulus control by the relational properties of sample and comparisons. Results showed a moderate effect: 40.6% of the participants passed the test after being exposed to a non-arbitrary relational matching task (but none without it). This research underlines the importance of non-arbitrary relational responses in the derivation of more complex repertoires.     

Reducing perceived social loafing in virtual teams: The effect of team feedback with guided reflexivity

The aim of this study was twofold. The first aim was to study the effect of an intervention combining team feedback and guided reflexivity on virtual teams' affective outcomes. The second was to examine the mediating role of perceived social loafing in this relationship. An experimental laboratory study was carried out with 54 teams randomly assigned to an experimental condition or a control condition. Results showed that this intervention had an effect on satisfaction with the result, but not on group cohesion and satisfaction with the team. Moreover, perceived social loafing fully mediated the effect of this intervention on group cohesion and partially mediated its effect on satisfaction with the team and the result.     

Perception of the teaching-learning process and academic achievement in diverse instructional contexts of Higher Education

In Higher Education, performance and Teaching-Learning (T-L) contexts are highly current concerns. Based on the DEDEPRO model, interdependence can be established between instructional contexts and levels of performance as they relate to the T-L process. Partitipants were 2020 pupils from two Spanish universities. Measurements of both variables were used in a quasi-experimental and correlational design. The univariate and causal analyses showed the effect of context on the T-L process and on performance; thus, the interdependent relationships between the latter and perception of the T-L process. Partial interaction effects also appeared, as well as a causal model of academic performance. Results are discussed and implications for the ECTS (European Credit Transfer System) are analyzed.
