Summary
The birthdate effect in sports extends to coaching. Players born earlier in the year are more likely to become minor hockey coaches, impacting the sport's talent pool.
Area of Science:
- Sports Science
- Sociology of Sport
- Human Kinetics
Background:
- The relative age effect (RAE) is well-documented in sports, showing players born just after a cutoff date are overrepresented.
- The RAE's influence on sports participation is known, but its impact on coaching roles remains unexplored.
Purpose of the Study:
- To investigate the presence and extent of a birthdate effect among minor ice hockey coaches.
- To determine if the RAE observed in players persists into coaching positions.
Main Methods:
- Data collected from 3,380 minor league ice hockey coaches in Québec for the 2023-2024 season.
- Analysis of coaches' birthdates to identify potential overrepresentation based on birth month and year.
Main Results:
- A significant birthdate effect was found, with individuals born in the first half of the year more likely to be coaches.
- This effect was pronounced in coaches born in the 1980s (53.42% vs. 46.58%) and after 1989 (55.73% vs. 44.27%).
- Coaches born before 1980 showed a reversed trend, suggesting a historical shift in the RAE's impact.
Conclusions:
- The birthdate effect in sports participation appears to extend to the coaching ranks in ice hockey.
- This suggests a potential loss of experienced players, who might otherwise have become coaches, due to the RAE.
- Understanding this effect is crucial for developing strategies to ensure a diverse and experienced coaching pool.

31.7K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

A relative frequency distribution is the proportion or fraction of times a value occurs in a data set. To find the relative frequencies, one can divide each frequency by the total number of data points in the sample. It is very similar to a regular frequency distribution, except that instead of reporting how many data values fall in a class, a relative frequency distribution reports the fraction of data values that fall in a class. These fractions or proportions are called relative frequencies...

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
