Maximilien “Max” Ringelmann
- One of the first researchers to study the relationship between process loss and group productivity. (1913)
- One of the founder in Social Psychology
Maximilien “Max” Ringelmann
Ringelmann Effect - The tendency, first documented by Max
Ringelmann, for people to become less productive when they work with others. This loss of efficiency increases as group size increases, but at a gradually decreasing rate.
Ringelmann Effect - One Person 100 units Two Person 186 units (200) Three Person Group 255 units (300) Eight Person Group 392 units (800)
Ringelmann Effect - There are two key sources of process loss
when worked together:•Motivational losses• Coordination losses
- “Groups become less productive as group size increases”
- The reduction of individual effort exerted when people work in groups compared to when they work alone is known as Social Loafing.- People carrying out all sorts of physical and mental (brainstorming, evaluating, monitoring & etc.) have been shown to exert less effort when they combine their efforts in a group situation.
Motivational Loss: Social Loafing
- Latane, Williams & Harkins examined social loafing by studying groups performing an extremely easy task: Making noise.
- Ringelmann effect, groups of participants made more noise than individuals, but groups failed to reach their potential.
Motivational Loss: Social Loafing
- Tested alone, 9.22 dynes/cm2
In dyads, each participant 66% of capacity Six-person groups,36%.
Motivational Loss: Social Loafing
- Social Loafing vs. Coordination Problems (Participants were led to believe that either one other participant or five other participants were shouting with them, but in actuality, they were working alone.)
- one other person was working , 82% five other persons were working, 74%
