The direct and indirect benefits of dispositional mindfulness on self-esteem and social anxiety

This study investigated the long‐term health effects of combat stress reaction (CSR) among Israeli CSR casualties (112) and control veterans (184) of the 1973 Yom Kippur war. Posttraumatic stress disorder (PTSD), physical symptoms, and adverse health practices were examined 18 years after the war. The relationship between CSR, PTSD, physical symptoms and adverse health practices was examined via hierarchical linear regression. Findings indicate that although CSR was positively associated with more current physical symptoms and adverse health practices in univariate analyses, these associations were not significant once demographic differences between the groups were controlled. In contrast, current PTSD symptoms were positively associated with current physical symptoms (p < 0.001) and showed a trend association with adverse health practices (p = 0.06). PTSD was the most powerful predictor of current physical symptoms and appears to mediate the association between CSR and physical symptoms almost two decades after the war. Both combat stress reaction and the results of the study were discussed in the light of the theory of Conservation of Resources (COR).     

The roles of leader emotion management and team conflict for team members' personal initiative: A multilevel perspective

Employees' personal initiative (i.e., their active and future-oriented engagement at work) is of high relevance to organizations that strive for innovation and competitiveness. To better understand its drivers and diminishers, the present study refers to Affective Events Theory and examines the impact of leader emotion management, team conflict, and affective well-being on personal initiative. Data from 300 members of 59 work teams in Germany were gathered from multiple sources at three points in time over the course of 2 weeks. Multilevel analyses indicated that leader emotion management positively affected team members' personal initiative and that this effect was mediated by team members' affective well-being. Data also revealed a contrasting negative indirect effect of task conflict within the team on team members' personal initiative via team members' affective well-being. The study's results suggest that the improvement of leaders' emotion management as well as the establishment of work conditions and experiences that foster affective well-being should be seriously considered by organizations wishing to facilitate personal initiative in team settings.     

The impact of interpersonal affective relationships and awareness on expertise seeking: A multilevel network investigation

Transactive memory theory suggests that general awareness of expertise location in a group is sufficient to predict expertise seeking. Yet expertise seeking is, at least in part, a social phenomenon between two individuals embedded in a network of social relationships. Taking a multilevel, network perspective, we examined the interplay of affective relationships and awareness on expertise seeking in groups. Hypotheses were tested using network data collected from 693 employees in 53 sales groups. HLM analysis results indicated that awareness of expertise distribution positively influenced the decision to seek expertise at all levels of analysis examined. In addition, both positive and negative affective relationships influenced expertise seeking, although their pattern of influence differed across different levels of analysis. More specifically, having either a positive or a negative affective relationship with another group member affected the decision to seek expertise from that person. Although having many positive relationships had a positive effect on expertise seeking, having many negative affective relationships had no effect. Moreover, having both an awareness and a positive affective relationship with another group member amplified their positive effect on expertise seeking. Last, individuals who had more negative affective ties were less likely to leverage the positive impact of each awareness relationship on expertise seeking.     

The validation of a religiosity measure for individuals with schizophrenia

Measures of religiosity validated for psychotic patients do not exist. This study sought to examine the psychometric properties of a modified version of the Religious Life Inventory (RLI) in this population. It was anticipated that religiosity would be affected by psychotic symptoms. The religiosity of patients with schizophrenia was assessed while symptoms were more evident and again after treatment, to evaluate changes in religiosity. Four factors were found which characterized the religiosity of people with schizophrenia. These factors were found to have good construct validity. Patient's responses indicated a reduced need for religion when re-assessed once symptom scores were reduced.     

Preferring alphabet–keyboard compatibility: Congruency between spatial codes shapes the affective connotation of letters

When letters are encountered, two spatial stimulus codes resulting from their positions within the alphabet and on the computer keyboard are activated mentally. If these two spatial codes match, letter processing is more efficient. The present study tested whether the processing fluency gain resulting from alphabet–keyboard compatibility also enhances affective evaluations of letters. In Experiment 1, participants preferred alphabet–keyboard compatible over incompatible letters in a forced-choice preference rating. Similarly, in Experiment 2, liking ratings for alphabet–keyboard compatible letters were higher compared to incompatible letters. Moreover, in Experiment 3, preference ratings of non-words were positively correlated with the relative number of alphabet–keyboard compatible letters within these letter strings. These findings suggest that alphabet–keyboard compatibility shapes the affective connotation of letters. Moreover, this processing fluency–valence association is activated at the level of letters as well as whole letter strings.     

Visual context does not promote concurrent sequence learning

Concurrent sequence learning (CSL) of two or more sequences refers to the concurrent maintenance, in memory, of the two or more sequence representations. Research using the serial reaction time task has established that CSL is possible when the different sequences involve different dimensions (e.g., visuospatial locations versus manual keypresses). Recently some studies have suggested that visual context can promote CSL if the different sequences are embedded in different visual contexts. The results of these studies have been difficult to interpret because of various limitations. Addressing the limitations, the current study suggests that visual context does not promote CSL and that CSL may not be possible when the different sequences involve the same elements (i.e., the same target locations, response keys and effectors).     

Activation of Political Attitudes: A Psychophysiological Examination of the Hot Cognition Hypothesis

The recording of event-related potentials (ERPs) in the brain has allowed for a better understanding of human sensory and cognitive processing. This technique may also prove useful in studying implicit social attitudes and their effects on information processing. Here, ERPs were used in a study of "hot cognition" in the context of political concepts. Hot cognition, as applied to the political domain, posits that all sociopolitical concepts that have been evaluated in the past are affectively charged, and that this affective charge is automatically activated from long-term memory within milliseconds of presentation of the political stimulus. During an evaluative priming task, ERP recordings showed that affectively incongruent prime/target pairs elicited an enhanced negativity with a peak latency of about 400 milliseconds relative to affectively congruent prime/target pairs. These differences suggest that automatic, implicit evaluations were made in response to strongly positive and negative political stimuli, and that these evaluations affected the subsequent processing of a high-valence adjective. Therefore, it appears that the emotional valence of a political prime is stored along with the concept itself, and that an affective response becomes active upon mere exposure to the political stimulus.     

Assessing affective experience of in-situ environmental walk via wearable biosensors for evidence-based design

In environmental psychology research, the most commonly used methods are phenomenological interviews and psychometric scales. Recently, with the development of wearable bio-sensing devices, a new approach based on bio-sensing data is becoming possible. In this study, we examined the feasibility of using wearable biosensors to document affective experience during in-situ walk. An eight-channelled Procomp multi-bio-sensing devices (EKG, EEG, skin conductance, temperature, facial EMG, respiration) were used, in addition with a GPS tracker, to measure the in situ physiological affective responses to environmental stimuli. This pilot experiment revealed consistent results between bio-sensing measures and two traditional methods, i.e. phenomenological interviews and psychological Likert scale rating, which indicated that mobile bio-sensing could be a promising method in measuring in-situ affective responses to environmental stimuli as well as diagnosing potential environmental stressor. This new bio-sensory method, as exemplified in this paper, could help identifying negative stressful stimuli and providing evidence-based diagnosis to support design strategies.     

Representing decision-makers using styles of behavior: An approach designed for group decision support systems

Supporting decision-making processes when the elements of a group are geographically dispersed and on a tight schedule is a complex task. Aiming to support decision-makers anytime and anywhere, Web-based group decision support systems have been studied. However, the limitations in the decision-makers’ interactions associated to this scenario bring new challenges. In this work, we propose a set of behavioral styles from which decision-makers’ intentions can be modelled into agents. The goal is that, besides having agents represent typical preferences of the decision-makers (towards alternatives and criteria), they can also represent their intentions. To do so, we conducted a survey with 64 participants in order to find homogeneous operating values so as to numerically define the proposed behavioral styles in four dimensions. In addition, we also propose a communication model that simulates the dialogues made by decision-makers in face-to-face meetings. We developed a prototype to simulate decision scenarios and found that agents are capable of acting according to the decision-makers’ intentions and fundamentally benefit from different possible behavioral styles, just as a face-to-face meeting benefits from the heterogeneity of its participants.     

Implicit sequence learning in ring‐tailed lemurs (Lemur catta)

Implicit learning involves picking up information from the environment without explicit instruction or conscious awareness of the learning process. In nonhuman animals, conscious awareness is impossible to assess, so we define implicit learning as occurring when animals acquire information beyond what is required for successful task performance. While implicit learning has been documented in some nonhuman species, it has not been explored in prosimian primates. Here we ask whether ring‐tailed lemurs (Lemur catta) learn sequential information implicitly. We tested lemurs in a modified version of the serial reaction time task on a touch screen computer. Lemurs were required to respond to any picture within a 2 × 2 grid of pictures immediately after its surrounding border flickered. Over 20 training sessions, both the locations and the identities of the images remained constant and response times gradually decreased. Subsequently, the locations and/or the identities of the images were disrupted. Response times indicated that the lemurs had learned the physical location sequence required in original training but did not learn the identity of the images. Our results reveal that ring‐tailed lemurs can implicitly learn spatial sequences, and raise questions about which scenarios and evolutionary pressures give rise to perceptual versus motor‐implicit sequence learning.
