Over the past 30 years, researchers studying group dynamics in sport have provided insight regarding the importance of considering a team’s environment, structure, and processes for its effective functioning. An emergent property resulting from activities within the group is cohesion. Cohesion is a dynamic property reflecting members’ perceptions of the unity and personal attractions to task and social objectives of the group. Generally speaking, cohesion remains a highly valued group property, and a strong body of evidence exists to support positive links to important individual and group outcomes such as adherence and team performance.
Given the importance attached to cohesion and other group variables for sport teams, coaches and athletes often attempt to engage in activities that facilitate group functioning. Team building is a specific approach designed to facilitate team effectiveness and individual members’ perceptions of their group. Cohesion has been the primary target of team-building interventions in sport, although recent work on team-building outcomes suggested that the effects of these interventions on cohesion may be limited. The most effective team-building approaches include a goal setting protocol, last at least two weeks in duration, and target a variety of outcomes in addition to cohesion, including individual cognitions and team performance. There is a clear need to identify a team’s requirements prior to intervening (i.e., a targeted approach), consider a variety of approaches to team building, and investigate the effects of team building via more stringent research methods.
Training is the systematic processes initiated by the organization that facilitate relatively permanent changes in the knowledge, skills, or affect/attitudes of organizational members. Cumulative meta-analytic evidence indicates that training is effective, producing, on average, moderate effect sizes. Training is most effective when designed so that trainees are active and encouraged to self-regulate during training, and when it is well-structured and requires effort on the part of trainees. Additional characteristics of effective training are: The purpose, objectives, and intended outcomes of training are clearly communicated to trainees; the training content is meaningful, and training assignments, examples, and exercises are relevant to the job; trainees are provided with instructional aids that can help them organize, learn, and recall training content; opportunities for practice in a safe environment are provided; feedback is provided by trainers, observers, peers, or the task itself; and training enables learners to observe and interact with others. In addition, effective training requires a prior needs assessment to ensure the relevance of training content and provides conditions to optimize trainees’ motivation to learn. After training, care should be taken to provide opportunities for trainees to implement trained skills, and organizational and social support should be in place to optimize transfer. Finally, it is important that all training be evaluated to ensure learning outcomes are met and that training results in increased job performance and/or organizational effectiveness.
Human visual development is a complex dynamic psychological/neurobiological process, being part of the developing systems for cognition, action, and attention. This article reviews current knowledge and methods of study of human visual development in infancy and childhood, in relation to typical early visual brain development, and how it can change in developmental disorders, both acquired (e.g., related to at-risk births) and genetic disorders. The newborn infant starts life with a functioning subcortical visual system which controls newborn orienting to nearby high contrast objects and faces. Although visual cortex may be active from birth, its characteristic stimulus selectivity and control of visual responses is generally seen to emerge around six to twelve weeks after birth. By age six months the infant has adequate acuity and contrast sensitivity in nearby space, and operating cortical mechanisms for discriminating colors, shapes, faces, movement, stereo depth, and distance of objects, as well as the ability to focus and shift attention between objects of interest. This may include both feedforward and feedback pathways between cortical areas and between cortical and subcortical areas. Two cortical streams start to develop and become interlinked, the dorsal stream underpinning motion, spatial perception and actions, and the ventral stream for recognition of objects and faces. The neural systems developing control and planning of actions include those for directed eye movements, reaching and grasping, and the beginnings of locomotion, with these action systems being integrated into the other developing subcortical and cortical visual networks by one year of age. Analysis of global static form (pattern) and global motion processing allows the development of dorsal and ventral streams to be monitored from infancy through childhood. The development of attention, visuomotor control and spatial cognition in the first years show aspects of function related to the developing dorsal stream, and their integration with the ventral stream.
The milestones of typical visual development can be used to characterize visual and visuo-cognitive disorders early in life, such as in infants with perinatal brain injuries and those born very prematurely. The concept of “dorsal stream vulnerability” is outlined. It was initially based on deficits in global motion sensitivity relative to static form sensitivity, but can be extended to the planning and execution of visuomotor actions and problems of attention, together with visuospatial and numerical cognition. These problems are found in the phenotype of children with both genetic developmental disorders (e.g., Williams syndrome, autism, fragile-X, and dyslexia), and in acquired developmental disorders related to very preterm birth, or in children with abnormal visual input such as congenital cataract, refractive errors, or amblyopia. However, there are subtle differences in the manifestation of these disorders which may also vary considerably across individuals. Development in these clinical conditions illustrates the early, but limited, plasticity of visual brain mechanisms, and provides a challenge for the future in designing successful intervention and treatment.

Study of the intersection of work with nonwork components of individuals’ lives has most often focused on roles within nuclear and extended families but is increasingly focused on nonwork domains beyond family, such as roles within friendships, communities, leisure activities, and the self. In line with the focus of most existing literature on the family-specific domain within nonwork lives, the nonwork domain will generally be referred to here as “family.” One popular conceptualization of linking mechanisms between work and family differentiates between work-family conflict or stress, which occurs when a work role and a nonwork role are not fully compatible and results in some type of physical or psychological strain. Alternatively, work-family enrichment occurs when participation in one role benefits life in the other role. Concepts similar to work-family enrichment include work-family positive spillover and work-family facilitation; all emphasize the ways in which one role can positively impact another role. Additionally, the popular concept of work-family balance highlights either a state of low conflict and high enrichment or the presence of effectiveness and satisfaction in both roles.
Broadly speaking, the links between work and family are bi-directional, such that the work domain can influence the family domain, the family domain can influence the work domain, and both can occur simultaneously. Work-family conflict and enrichment have been tied to important employee outcomes, including work (e.g., absenteeism), family (e.g., family satisfaction), and domain-unspecific outcomes (e.g., physical and psychological health), as well as to organizational outcomes (e.g., market performance). Working conditions contributing to work-family conflict and enrichment are frequently characteristic of lower wage jobs, such as low levels of control over work, high work demands, low levels of supervisor support, shift work, and temporary work that can lead to unpredictable schedules, high degrees of job insecurity, and increased health and safety hazards. Researchers are presented with unique challenges as the workplace continues to change, with more dual-earner couples, an increasingly aging workforce, and surges of technology that facilitates flexible work arrangements (e.g., telecommuting). Nonetheless, researchers and organizations work to explore relationships between work and family roles, develop policies related to work and family (i.e., national, state or local, and organizational), and build evidence-based interventions to improve organizations’ abilities to meet employees’ needs.

Work stress refers to the process of job stressors, or stimuli in the workplace, leading to strains, or negative responses or reactions. Organizational development refers to a process in which problems or opportunities in the work environment are identified, plans are made to remediate or capitalize on the stimuli, action is taken, and subsequently the results of the plans and actions are evaluated. When organizational development strategies are used to assess work stress in the workplace, the actions employed are various stress management interventions. Two key factors tying work stress and organizational development are the role of the person and the role of the environment. In order to cope with work-related stressors and manage strains, organizations must be able to identify and differentiate between factors in the environment that are potential sources of stressors and how individuals perceive those factors. Primary stress management interventions focus on preventing stressors from even presenting, such as by clearly articulating workers’ roles and providing necessary resources for employees to perform their job. Secondary stress management interventions focus on a person’s appraisal of job stressors as a threat or challenge, and the person’s ability to cope with the stressors (presuming sufficient internal resources, such as a sense of meaningfulness in life, or external resources, such as social support from a supervisor). When coping is not successful, strains may develop. Tertiary stress management interventions attempt to remediate strains, by addressing the consequence itself (e.g., diabetes management) and/or the source of the strain (e.g., reducing workload). The person and/or the organization may be the targets of the intervention. The ultimate goal of stress management interventions is to minimize problems in the work environment, intensify aspects of the work environment that create a sense of a quality work context, enable people to cope with stressors that might arise, and provide tools for employees and organizations to manage strains that might develop despite all best efforts to create a healthy workplace.
