Frustration and Conflict: Approach-Approach, Approach-Avoidance

90
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 Avoidance01:14

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

115
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...

Theories of Dissolution: Diffusion Layer Model

811
Dissolution, the process by which drug particles dissolve in a solvent, is explained by the diffusion layer model, a theoretical framework that simulates the absorption of oral drugs and allows us to analyze experimental data.
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...

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...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Relationship Formation

40.1K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

A revised diffusion model for conflict tasks (RDMC) improves upon the original by adhering to inhibition/suppression limits, accurately predicting conflict data and explaining task differences.

Area of Science:

  • Cognitive Psychology
  • Computational Neuroscience
  • Human Information Processing

Background:

  • The diffusion model for conflict tasks (DMC) explains conflict task data within an evidence accumulation framework.
  • DMC assumes distractor evidence is rapidly accumulated and then withdrawn, implying qualitative representational changes over time.
  • This 'changing sign' of distractor evidence is theoretically problematic, suggesting a need for alternative models.

Purpose of the Study:

  • To develop a revised diffusion model for conflict tasks (RDMC) that operates strictly within inhibition/suppression limits.
  • To demonstrate RDMC's ability to predict the full range of observed delta plots.
  • To provide an excellent fit to Simon and flanker task data, benchmarking against the original DMC.

Main Methods:

  • Developed a revised diffusion model (RDMC) where evidence strength changes monotonically but does not change sign.
  • Utilized existing datasets from Simon and flanker tasks, previously used to benchmark the original DMC.
  • Analyzed model fits at both individual and group levels.

Main Results:

  • RDMC successfully predicts the full spectrum of delta plots (positive-going and negative-going).
  • RDMC provides excellent fits to Simon and flanker task data, comparable to the original DMC.
  • The model elucidates processing differences between Simon and flanker tasks, particularly on congruent trials.

Conclusions:

  • RDMC offers a more theoretically sound account of conflict processing dynamics by adhering to inhibition/suppression principles.
  • The model explains task differences by proposing distinct attentional shifting dynamics on congruent trials in Simon versus flanker tasks.
  • RDMC underscores the critical role of dynamic interactions between top-down goals and bottom-up stimulus effects in cognitive conflict resolution.
