English: A trait under positive selection. The blue dashed line shows the current mean population trait value, the red dashed line shows the mean population trait value in the next generation. Because high trait values are associated with higher fitness the the mean trait value increases due to selection.
Empirical research findings suggest that the positivity effect can be influenced by internal positive speech, where engaging in constructive self-dialogue can significantly improve one’s ability to perceive and react to challenging situations more optimistically.
Example for a trait under positive selection. The Price equation shows that a change in the average amount of a trait in a population from one generation to the next is determined by the covariance between the amounts of the trait for subpopulation and the fitnesses of the subpopulations, together with the expected change in the amount of the trait value due to fitness, namely ():
Frequency-dependent selection is an evolutionary process by which the fitness of a phenotype or genotype depends on the phenotype or genotype composition of a given population. In positive frequency-dependent selection, the fitness of a phenotype or genotype increases as it becomes more common.
Barbara S. Held, a professor at Bowdoin College, argues that positive psychology has faults: negative side effects, negativity within the positive psychology movement, and the division in the field of psychology caused by differing opinions of psychologists on positive psychology. She notes the movement's lack of consistency regarding the role ...
Several recalls were issued in 2024 for Ford Motor Company vehicles. The recall report data is from Jan. 1, 2024, to Dec. 27, 2024. The U.S. Department of Transportation (DOT) compiles data from ...
Kin selection can explain altruistic behavior towards close relatives even at the cost of their own's survival, as long as one's sacrifice can help preserve a greater amount of the same genes in close relatives. [10] For example, worker bees can die from attacking their predators in order to help preserve other bees' genes. [7]
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
