Frustration and Conflict: Approach-Approach, Approach-Avoidance01:20

Frustration and Conflict: Approach-Approach, Approach-Avoidance

505
Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

638
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Cognitive Dissonance

36.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Social Traps01:41

Social Traps

26.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Summary

Genomic imprinting influences risk tolerance. Paternally expressed genes favor risk aversion to reduce reproductive variance, while maternally expressed genes promote risk tolerance.

Area of Science:

  • Evolutionary biology
  • Genetics
  • Neuroscience

Background:

  • Genomic imprinting, where gene expression depends on parental origin, arises from intragenomic conflict.
  • Imprinted genes are crucial in brain function and linked to risk-related behaviors.
  • Evolutionary bet-hedging explains selection for traits that reduce reproductive variance.

Purpose of the Study:

  • To analyze an evolutionary bet-hedging model incorporating imprinted gene expression.
  • To investigate how differing parental reproductive variances affect selection on imprinted alleles.
  • To link theoretical predictions to empirical observations of imprinted genes and behavior.

Main Methods:

  • Developed a mathematical model of evolutionary bet-hedging.
  • Incorporated sex-specific reproductive variances into the model.
  • Analyzed the trade-offs between mean reproductive success and variance reduction for imprinted alleles.

Main Results:

  • Selection favors variance reduction more strongly for paternally inherited alleles when males have higher reproductive variance.
  • Paternally expressed imprinted genes are predicted to promote risk-averse behaviors.
  • Maternally expressed imprinted genes are predicted to promote risk-tolerant behaviors.

Conclusions:

  • The parental origin of imprinted alleles influences behavioral strategies related to reproductive risk.
  • Empirical data on delay discounting and social dominance align with these predictions.
  • Further research can test these hypotheses on imprinted gene function and behavior.
