Dominant and Dominated Strategies
0 Views •
2025
In strategic decision-making, a dominant strategy is one that always provides the best outcome for a player, no matter what the other players decide. This ensures that the player's payoff is maximized regardless of the choices made by others. On the other hand, a dominated strategy consistently leads to a worse outcome than another available strategy, regardless of the opponent's decision. For instance, imagine two firms competing in a market by setting production levels—either high or low.

Assessing Social Dominance in Mouse Models Using the Tube Test

This protocol describes a behavioral assay to evaluate social dominance in rodents using the tube test. Social dominance remains stable over time, and several models of developmental and neurological disorders exhibit robust social dominance abnormalities. Therefore, the tube test serves as a convenient outcome measure for mechanistic studies or preclinical therapeutic screening.

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism. According to Mendel, organisms with both copies or a single copy of the dominant allele display a...

Equilibrium in Dominant Strategies

2025
In game theory, equilibrium in dominant strategies arises when each player selects their optimal strategy independently of others' choices. This simplifies analysis since each player's best decision is predictable without considering opponents' actions. Understanding Dominant Strategy Equilibrium A dominant strategy consistently offers the best outcome for a player, regardless of the choices of other players. When all players adopt their dominant strategies, the game reaches a stable...

The Rubber Hand Illusion

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...
FAQs
During a skilled action, the motor cortex contributes to movement planning and control, while the opposite cerebral hemisphere primarily governs the active hand. The corpus callosum supports communication between hemispheres, and sensory systems provide information that helps coordinate movement. Examining these interacting systems lets neuroscientists relate a behavioral preference to broader patterns of brain asymmetry.
Hand use depends on more than motor output alone. Sensory systems contribute information that supports perception and coordinated movement, allowing researchers to examine how a person’s preferred hand functions within a wider sensorimotor organization. This perspective connects observable performance with the neural processes involved in controlling, monitoring, and refining skilled actions.
Practice provides an important context for interpreting preferred hand use because repeated skilled actions are relevant to motor learning. Researchers can therefore examine how hand preference relates to learned performance rather than treating it as an isolated behavior. These studies contribute to understanding individual differences in sensorimotor organization and the neural development associated with skilled movement.
Patterns of preferred hand use offer a behavioral way to investigate brain asymmetry, because movement of one side of the body is primarily controlled by the opposite cerebral hemisphere. When combined with information about motor, sensory, and interhemispheric systems, hand-preference findings help researchers study how neural organization differs across individuals.
Researchers can assess hand preference through tasks that represent skilled everyday actions, including writing, throwing, and manipulating objects. Comparing performance or reported preference across these activities provides information about consistency in hand use. Such assessments support investigations of coordination, individual differences, and the relationship between observable behavior and sensorimotor organization.
Handedness tasks can provide evidence relevant to coordination, motor learning, neural development, and individual differences in sensorimotor organization. Their value comes from connecting task performance with broader questions about lateralization and brain asymmetry. They may also help researchers examine how motor behavior changes in contexts involving rehabilitation or recovery after injury.
Neuroscientists study dominant hand use in rehabilitation because hand-preference tasks can help examine coordination and recovery after injury. Observing performance on familiar skilled actions provides a way to investigate motor function in relation to neural organization. This context links behavioral assessment with research on how movement and sensorimotor systems are affected during recovery.
