Selection, training, cohesion and psychosocial adaptation influence performance and, as such, are relevant factors to consider while preparing for costly, long-duration[ clarification needed ] spaceflight missions in which the performance objectives will be demanding, endurance will be tested and success will be critical.
During the selection of crew members, throughout their training and during their psychosocial adaptation to the mission environment, there are several opportunities to encourage optimal performance and, in turn, minimize the risk of failure.
Evidence linking crew selection, composition, training, cohesion or psychosocial adaptation to performance errors is uncertain. Many NASA-backed studies regarding spaceflight, as well as space analogs, emphasize the need to consider these factors. [1] [2] [3] [4] [5] [6] The research on performance errors caused by team factors is ambiguous and currently, no systematic attempt has been undertaken to measure performance errors due to psychosocial team factors during space flight.
As a result, evidence does not help identify what is needed to reduce the risk of performance errors in space. Ground-based evidence demonstrates that decrements in individual and team performance are related to the psychosocial characteristics of teamwork. Also, there are reasons to believe that ground support personnel and crew members experience many of the same basic issues regarding teamwork and performance. [2] [6] [7]
The study of performance errors implies that human actions may be simplified into a dichotomy of "correct" or "incorrect" responses. It has been argued that this dichotomy is a harmful oversimplification, and that it would be more productive to focus on the variability of human performance and how organizations can manage that variability. [8]
There are two particular problems that occur when focusing on performance errors:
Research shows that humans are fairly adept at correcting or compensating for performance errors before such errors result in recognizable or recordable failures. [8] Most failures are recorded only when multiple errors occur and are not preventable. [9]
For NASA's purposes, a team is commonly understood to be a collection of individuals that is assigned to support and achieve a particular mission. One way of selecting for teams is to identify those individuals who are best suited to work in teams, ensuring that each individual team member possesses the qualities and skills that lend themselves to optimal teamwork. Many organizations use competency frameworks to select individuals utilizing a "team-working" competency that measures how an individual works with other team members (support, knowledge sharing, etc.). [10] These "teamwork" competencies have been shown to help predict individual performance in teams.
Efforts have been made within spaceflight operations to identify factors that are important for selecting individual crew members for long duration spaceflight. [2] [4] [6] [11] [12] [13] [14] There has also been an analytical study to identify the skills necessary for long and short duration missions to inform the initial astronaut candidate selection process. [12] In this study, twenty experts (including astronauts) rated 47 relevant skills on criticality and another 42 environmental and work demands on their probability of occurrence.
This resulted in 10 broad factors that were deemed important for long-duration missions:
These factors somewhat overlap with those identified in previous peer-rating studies which suggest both a job competence and an interpersonal dimension for astronaut performance. [15] [16]
There is a lack of data that related performance to team composition and cohesion due to the evolution of job duties and selection practices over the history of manned spaceflight as well as the limited number of astronauts actually selected (340 U.S. astronauts to date). These issues are relevant to other space agencies as well. In 1990, a European astronaut working group reevaluated selection criteria for the selection of European astronauts as Russian researchers have collected personality data on cosmonauts for a number of years. [17] The empirical linking of personality factors to specific performance levels still eludes researchers.

Long-duration space flights are so physically, mentally and emotionally demanding that simply selecting individual crew members who have the "right stuff" is insufficient. [51] Training and supporting optimal performance is more effective than simply selecting high performers. [52] Training team skills and supporting optimal performance entails more than educating astronauts about the technical aspects of the job, it also requires equipping those astronauts with the resources that are needed to maintain psychological and physical health during long-duration spaceflight missions.
Developing the right kind of training for team skills is further complicated by operational issues. Not all tasks that will or may be encountered can be anticipated. Unexpected tasks can, and have, arise suddenly. Team training needs to be broad and flexible enough to support these unexpected performance requirements.
Group cohesiveness has been defined as the strength of members' motivations to stay in the group. [53] Leon Festinger cited three primary characteristics that define team cohesion: interpersonal attraction, task commitment and group pride. Studies to determine the strength or willingness of individuals to stick together and act as a unit have most consistently assessed the level of conflict, degree of interpersonal tensions, facility and quality of communications, collective perceptions of team health and performance of the group, and the extent to which team members share perceptions or understandings concerning their operational context.
Researchers at the U.S. Army Research Institute (ARI) noted in their recent review of cohesion as a construct, that the definitions of cohesion is ambiguous; therefore, the means of measuring cohesion is complex. The ARI authors concluded that "cohesion can best be conceptualized as a multidimensional construct consisting of numerous factors representing interpersonal and task dynamics. [34] There is a large body of ground-based evidence showing cohesion influences levels of performance, but this evidence is primarily correlational rather than causal.
Cohesive teams are more productive than less cohesive teams. This situation could be because
or
Teams preserve their cohesion when they succeed rather than fail. Therefore, applied scientists advise it is important to promote three essential conditions for team performance:
These kinds of problems undermine team performance and can have detrimental effects on team cohesion (Thompson, 2002).
Research shows that cohesive teams tend to sit closer to each other, focus more attention on each other, show signs of mutual affection, display coordinated patterns of behavior as well as give due credit to their partners. Non-cohesive teams are more likely to take credit for successes and blame others for mistakes and failures. [54] It is important to differentiate between team cohesiveness and individual morale. An individual who has low morale can influence team cohesion, but it may be possible for a team to remain cohesive even with low-morale members.

Psychosocial experts within the spaceflight community have articulated their concern that interpersonal conflicts and lack of cohesion will impede the abilities of crews to perform tasks accurately, efficiently, or in a coordinated manner during long-duration missions. [2] [4] [6]
From the evidence, it cannot be said that lack of team cohesion is statistically likely to result in numerous performance errors or an observable failure, but it does seem likely that ignoring the relationship between cohesion and performance will result in sub-optimal performance. [34] We know that many factors contribute to how cohesion is built and encouraged within a team, and we know that cohesion is positively related to better performance. Research cannot effectively determine in a reasonable amount of time what minimum level of cohesion is required to avoid catastrophic failure. Instead of investing research and time in such an endeavor, funding would be better used to test and identify effective means of building cohesion and promoting optimal performance in a long-duration mission context.
Although the astronaut candidate selection process screens for individuals with personality or mood disorders, certain disorders (i.e. poor psychosocial adaptation) may develop due to poor cohesion and/or support is a concern that could ultimately decrease performance in space flight crews.
Although spaceflight evidence regarding cohesion and performance is limited by the scarcity of objective team performance data, case studies, interviews and surveys have been conducted within the spaceflight community that have provided evidence that issues pertaining to cohesion exist and are perceived as threats to effective operations. For example, breakdowns in team coordination, resource and informational exchanges, and role conflicts (all common indicators of poor team cohesion) were mentioned as contributors to both the Challenger and the Columbia space shuttle accidents. [66] [67] Likewise, interviews and surveys of flight controllers indicate that mission teams are commonly concerned with team member coordination and communications, and that interpersonal conflicts and tensions do exist. [11] [68]
Because of a lack of empirical evidence from spaceflight research, much of the evidence surrounding cohesion and performance comes from non-space domains such as aviation, medicine, the military, and space analogs. Some reports have estimated that "crew error" in aviation contributes 65% to 70% of all serious accidents. [7] [69] The resulting accident investigations and mishap reports note poor teamwork, communication, coordination, and tactical decision-making as significant causal factors in mishap samples [70] and team breakdowns are repeatedly implicated in accidents. [71] [72] Interpersonal conflicts, miscommunications, failures to communicate, and poor teamwork skills have been shown to contribute significantly to the rate of errors in the medical field. [35] [58] [73]
Meta-analyses conducted in various industries and types of performance teams (work, military, sport, educational, etc.) provide additional ground-based evidence that cohesion is related to performance. The authors of these meta-analyses (Evans and Dion) [74] found a positive correlation between cohesion and individual performance, but did not include group performance criterion measures. Mullen and Copper [75] found that cohesion positively affects performance. They also found that this relationship was stronger in real teams verses ad hoc teams, in small teams verses large teams as well as in field studies. Mullen and Copper [75] also noted that successful performance also promotes cohesion and numerous performance outcomes including individual and group performance, behavioral health, job satisfaction, readiness to perform, and absence of discipline problems.
In the later meta-analyses, it was found that as work required more collaboration, the cohesion-performance relationship became stronger and highly cohesive teams became more likely to perform better than less-cohesive teams. [76] This conclusion coincides with Thompson's [54] cumulated field study finding that cohesion facilitates team processes and team coordination among work teams in various industrial settings.

A significant positive relationship between performance and the generalized beliefs of team members concerning the capabilities of their team across different situations. [81] Although most research on team cohesion and performance concentrate on the positive aspects of team attitudes, some have investigated the level of conflict and negative attitudes concerning the team as indicators of cohesion. De Dreu and Weingart [82] noted an important distinction between interpersonal conflict and task conflict (defined, interpersonal conflicts are about relationship issues, whereas task conflicts are about how to handle tasks).
Interpersonal conflict is generally detrimental to team cohesion, and, in turn, is destructive to team performance. While team members may correct each other, offer alternatives and argue about how to solve a problem, some level of task-related conflict can promote optimal performance. [83] In contrast, interpersonal and task-related aspects of cohesion are generally found to influence performance positively. A study conducted with Canadian military groups showed that task-related cohesion was positively related to individual job satisfaction, interpersonal cohesion was negatively related to reports of psychological distress, and both types of cohesion were positively related to job performance. [78]
Research conducted on Antarctic space analogs investigated conflict, cohesion and performance. It was found that:
This last point was studied over a ten-year period, modeling individual and group effects on adaptation to life in an extreme environment using multilevel analysis (Category III).
The military and aviation industries have focused more on task cohesion and shared mental models (SMMs) in their cohesion studies. SMMs refer to implicit agreements in team member expectations concerning how things work and what behaviors will result in various conditions and were proposed to characterize cohesive work teams. [28] [31] [35] Studies that compare performance during simulated operations and training note that
Leadership, or the ability to influence others toward achieving group goals, [87] may also play a role in team cohesion. Although there is an abundance of research that exists for this topic, much of it is complex and conflicting and the findings are often mixed. Many studies are at the individual level and may not generalize to the spaceflight setting. Studies have shown a supporting relationship between different types of leadership styles, individual performance and morale. [88] [89]
Industrial and organizational psychology "focuses the lens of psychological science on a key aspect of human life, namely, their work lives. In general, the goals of I-O psychology are to better understand and optimize the effectiveness, health, and well-being of both individuals and organizations." It is an applied discipline within psychology and is an international profession. I-O psychology is also known as occupational psychology in the United Kingdom, organisational psychology in Australia and New Zealand, and work and organizational (WO) psychology throughout Europe and Brazil. Industrial, work, and organizational (IWO) psychology is the broader, more global term for the science and profession.
Team building is a collective term for various types of activities used to enhance social relations and define roles within teams, often involving collaborative tasks. It is distinct from team training, which is designed by a combination of business managers, learning and development/OD and an HR Business Partner to improve the efficiency, rather than interpersonal relations.
Work design is an area of research and practice within industrial and organizational psychology, and is concerned with the "content and organization of one's work tasks, activities, relationships, and responsibilities" (p. 662). Research has demonstrated that work design has important implications for individual employees, teams, organisations, and society.
Teamwork is the collaborative effort of a group to achieve a common goal or to complete a task in an effective and efficient way. Teamwork is seen within the framework of a team, which is a group of interdependent individuals who work together towards a common goal.
Space Medicine is a subspecialty of Emergency Medicine which evolved from the Aerospace Medicine specialty. Space Medicine is dedicated to the prevention and treatment of medical conditions that would limit success in space operations. Space medicine focuses specifically on prevention, acute care, emergency medicine, wilderness medicine, hyper/hypobaric medicine in order to provide medical care of astronauts and spaceflight participants. The spaceflight environment poses many unique stressors to the human body, including G forces, microgravity, unusual atmospheres such as low pressure or high carbon dioxide, and space radiation. Space medicine applies space physiology, preventive medicine, primary care, emergency medicine, acute care medicine, austere medicine, public health, and toxicology to prevent and treat medical problems in space. This expertise is additionally used to inform vehicle systems design to minimize the risk to human health and performance while meeting mission objectives.
Transactive memory is a psychological hypothesis first proposed by Daniel Wegner in 1985 as a response to earlier theories of "group mind" such as groupthink. A transactive memory system is a mechanism through which groups collectively encode, store, and retrieve knowledge. Transactive memory was initially studied in couples and families where individuals had close relationships but was later extended to teams, larger groups, and organizations to explain how they develop a "group mind", a memory system that is more complex and potentially more effective than that of any of its individual constituents. A transactive memory system includes memory stored in each individual, the interactions between memory within the individuals, as well as the processes that update this memory. Transactive memory, then, is the shared store of knowledge.
Greenberg (1987) introduced the concept of organizational justice with regard to how an employee judges the behavior of the organization and the employee's resulting attitude and behaviour. For example, if a firm makes redundant half of the workers, an employee may feel a sense of injustice with a resulting change in attitude and a drop in productivity.
Group cohesiveness, also called group cohesion or social cohesion, arises when bonds link members of a social group to one another and to the group as a whole. Although cohesion is a multi-faceted process, it can be broken down into four main components: social relations, task relations, perceived unity, and emotions. Members of strongly cohesive groups are more inclined to participate readily and to stay with the group.
Training and development involve improving the effectiveness of organizations and the individuals and teams within them. Training may be viewed as related to immediate changes in organizational effectiveness via organized instruction, while development is related to the progress of longer-term organizational and employee goals. While training and development technically have differing definitions, the two are oftentimes used interchangeably and/or together. Training and development have historically been topics within adult education and applied psychology but have within the last two decades become closely associated with human resources management, talent management, human resources development, instructional design, human factors, and knowledge management.
Workplace aggression is a specific type of aggression which occurs in the workplace. Workplace aggression is any type of hostile behavior that occurs in the workplace. It can range from verbal insults and threats to physical violence, and it can occur between coworkers, supervisors, and subordinates. Common examples of workplace aggression include gossiping, bullying, intimidation, sabotage, sexual harassment, and physical violence. These behaviors can have serious consequences, including reduced productivity, increased stress, and decreased morale.
Job performance assesses whether a person performs a job well. Job performance, studied academically as part of industrial and organizational psychology, also forms a part of human resources management. Performance is an important criterion for organizational outcomes and success. John P. Campbell describes job performance as an individual-level variable, or something a single person does. This differentiates it from more encompassing constructs such as organizational performance or national performance, which are higher-level variables.
Groupthink is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Cohesiveness, or the desire for cohesiveness, in a group may produce a tendency among its members to agree at all costs. This causes the group to minimize conflict and reach a consensus decision without critical evaluation.
Counterproductive work behavior (CWB) is employee's behavior that goes against the legitimate interests of an organization. This behavior can harm the organization, other people within it, and other people and organizations outside it, including employers, other employees, suppliers, clients, patients and citizens. It has been proposed that a person-by-environment interaction (the relationship between a person's psychological and physical capacities and the demands placed on those capacities by the person's social and physical environment.) can be utilized to explain a variety of counterproductive behaviors. For instance, an employee who is high on trait anger is more likely to respond to a stressful incident at work with CWB.
Team composition refers to the overall mix of characteristics among people in a team, which is a unit of two or more individuals who interact interdependently to achieve a common objective. It is based on the attributes among individuals that comprise the team, in addition to their main objective.
Astronaut training describes the complex process of preparing astronauts in regions around the world for their space missions before, during and after the flight, which includes medical tests, physical training, extra-vehicular activity (EVA) training, wilderness survival training, water survival training, robotics training, procedure training, rehabilitation process, as well as training on experiments they will accomplish during their stay in space.
Psychological and sociological effects of space flight are important to understanding how to successfully achieve the goals of long-duration expeditionary missions. Although robotic spacecraft have landed on Mars, plans have also been discussed for a human expedition, perhaps in the 2030s, for a return mission.
Team effectiveness is the capacity a team has to accomplish the goals or objectives administered by an authorized personnel or the organization. A team is a collection of individuals who are interdependent in their tasks, share responsibility for outcomes, and view themselves as a unit embedded in an institutional or organizational system which operates within the established boundaries of that system. Teams and groups have established a synonymous relationship within the confines of processes and research relating to their effectiveness while still maintaining their independence as two separate units, as groups and their members are independent of each other's role, skill, knowledge or purpose versus teams and their members, who are interdependent upon each other's role, skill, knowledge and purpose.
Abusive supervision is most commonly studied in the context of the workplace, although it can arise in other areas such as in the household and at school. "Abusive supervision has been investigated as an antecedent to negative subordinate workplace outcome." "Workplace violence has combination of situational and personal factors". The study that was conducted looked at the link between abusive supervision and different workplace events.
Space psychology refers to applying psychology to advise human spaceflight. This includes applying industrial and organizational psychology to team selection, individual and team mental preparation, team training, and ongoing psychological support, and applying human factors and ergonomics to the construction of spacecraft to ensure sufficient habitability.
Team diversity refers to the differences between individual members of a team that can exist on various dimensions like age, nationality, religious background, functional background or task skills, sexual orientation, and political preferences, among others. Different types of diversity include demographic, personality and functional diversity, and can have positive as well as negative effects on team outcomes. Diversity can impact performance, team member satisfaction or the innovative capacity of a team. According to the Input-Process-Output Model, team diversity is considered an input factor that has effects on the processes as well as on the team outputs of team work.
