Ecology and Evolution of Communication in Social Insects
2016
Insect life strategies comprise all levels of sociality from solitary to eusocial, in which individuals form persistent groups and divide labor. With increasing social complexity, the need to communicate a greater diversity of messages arose to coordinate division of labor, group cohesion, and concerted actions. Here we summarize the knowledge on prominent messages in social insects that inform about reproduction, group membership, resource locations, and threats and discuss potential evolutionary trajectories of each message in the context of social complexity.
Behavioural responses of fish groups exposed to a predatory threat under elevated CO2
2019
Most of the studies dealing with the effects of ocean acidification (OA) on fish behaviour tested individuals in isolation, even when the examined species live in shoals in the wild. Here we evaluated the effects of elevated CO2 concentrations (i.e. ∼900 μatm) on the shelter use and group cohesion of the gregarious damselfish Chromis viridis using groups of sub-adults exposed to a predatory threat. Results showed that, under predatory threat, fish reared at elevated CO2 concentrations displayed a risky behaviour (i.e. decreased shelter use), whereas their group cohesion was unaffected. Our findings add on increasing evidence to account for social dynamics in OA experiments, as living in gro…
Propagule dispersal and larval patch cohesiveness in a Mediterranean coastal fish
2016
The assessment of fish dispersal is fundamental for both conservation and management of fishery resources as it provides crucial information for the establishment of more effective marine protected areas (MPAs) and networks of MPAs. In this study, we investigated the elemental composition of otoliths in early life stages of the saddled sea bream Oblada melanura (Linnaeus, 1758) (Perciformes: Sparidae) in order to obtain information on its propagule (egg and larva) dispersal in the south-western Mediterranean Sea. Specifically, using pre-settlement individuals we investigated (1) larval patch cohesiveness during the last phase of larval life; and with early post-settlement individuals we inv…
Group cohesion, needs satisfaction, and self-regulated learning: A one-year prospective study of elite youth soccer players' perceptions of their clu…
2018
Abstract Objectives With an overarching aim of investigating the importance of group perceptions on factors believed to underpin the quantity and quality of athletic practice, the purpose of the present study was to examine the relationship between perceptions of group cohesion and elite youth soccer players' basic psychological needs satisfaction and self-regulation over a one-year period. Design Prospective study design involving data collection at two time-points over a one-year period. Method A total of 332 elite youth soccer players selected at Norwegian regional U14 (N = 154) and U 13 (N = 178) levels completed questionnaires measuring perceptions of club-team cohesion, and individual…
The Role of Work Group in Individual Sickness Absence Behavior
2008
The purpose of our two-year follow-up study was to examine the effect of the social components of the work group, such as group absence norms and cohesion, on sickness absence behavior among individuals with varying attitudes toward work attendance. The social components were measured using a questionnaire survey, and data on sickness absence behavior were collected from the employers' records. The study population consisted of 19,306 Finnish municipal employees working in 1,847 groups (78% women). Multilevel Poisson regression modeling was applied. The direct effects of work group characteristics on sickness absence were mostly insignificant. In contrast, both of the social components of …
Social, Occupational, and Cultural Adaptation During a 12-Month Wintering in Antarctica.
2016
Background and methods Life in isolated and confined environments (ICEs) is subject to important constraints which can generate psychosociologically impaired outcomes. This study investigated psychological, social, occupational, and cultural variables which are among the most important determinants in adaptation to a one-year wintering in Antarctica for 13 international subjects. Results Our findings confirm and give further insight into the role of social (Cohesiveness, Social Support) and occupational (Implementation/Preparedness, Counterproductive Activity, Decision Latitude, and Psychological Job Demands) dimensions of adaptation to ICEs. Relationships between various social and occupat…
Were we stressed or was it just me – and does it even matter? Efforts to disentangle individual and collective resilience within real and imagined st…
2020
Although resilience is a multi-level process, research largely focuses on the individual and little is known about how resilience may distinctly present at the group level. Even less is known about subjective conceptualizations of resilience at either level. Therefore, two studies sought to better understand how individuals conceptualize resilience both as an individual and as a group. Study 1 (N = 123) experimentally manipulated whether participants reported on either individual or group-based responses to real stressors and analysed their qualitative responses. For individual responses, subjective resilience featured active coping most prominently, whereas social support was the focus for…
Rules and agreements — And becoming a preschool community of learners
2005
SUMMARY The study presented here discusses rules and agreements in a preschool group from the viewpoint of the development of a community of learners. What kinds of rules and agreements exist in the preschool group, how they are articulated and how they are adopted at the beginning of the preschool year were the questions addressed in this small-scale ethnographic study. Three types of rules, often called agreements in preschools, were found in the group: conventional, moral and prudential rules. Conventional rules were mentioned and referred to most frequently, by both teachers and children. The most typical way of articulating a rule was stating the rule or reminding others of it. Many ru…
Loafing in the digital age: The role of computer mediated communication in the relation between perceived loafing and group affective outcomes
2014
Virtual work has become an increasingly central practice for the organization of the 21st century. While effective virtual workgroups can create synergies that boost innovation and performance, ineffective workgroups become a great burden for organizations. Empirical research has shown that some negative behaviors, such as social loafing, negatively influence a group's affective outcomes, in both collocated (face-to-face) and virtual workgroups. In this study, we explore if working through low fidelity computer mediated communication (CMC) increases the negative impact of perceived loafing over cohesion and work satisfaction. On this rationale, we conducted a laboratory study with 44 groups…
Group cohesion in group-based personal practice
2021
AbstractBackgroundPersonal practice (PP) is an integral component of many psychotherapy training programmes. It aims to promote personal and professional growth and is often conducted in a group format (g-PP). Group cohesion is one of the most researched mechanisms in group psychotherapy, but has rarely been studied in the context of g-PP.Aims and methodThis exploratory study examines the associations between cohesion, satisfaction with g-PP, its impact on personal and professional development, and theoretical orientation in a sample of n = 329 German psychotherapy trainees. Cohesion was assessed with the group questionnaire (GQ-D; Positive Bonding, Positive Working, Negative Relationship).…
