Decision Making: P-value Method01:09

Decision Making: P-value Method

7.1K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Lazarus's Cognitive Appraisal Theory

2.5K
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

Criteria for Causality: Bradford Hill Criteria - II01:28

Criteria for Causality: Bradford Hill Criteria - II

1.5K
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

Criteria for Causality: Bradford Hill Criteria - I

1.4K
The Bradford Hill criteria are a group of principles that provide a framework to determine a causal relationship between a specific factor and a disease. There are nine criteria that are pivotal in assessing causality in epidemiological studies. Here's a closer look at Strength, Consistency, Specificity, and Temporality criteria with definitions and examples:

Equity Theory01:26

Equity Theory

362
Equity theory explains how our sense of fairness influences the dynamics of close relationships. Rooted in social psychology, the theory posits that individuals evaluate fairness by comparing the ratio of their contributions to the rewards they receive. Relationship satisfaction is highest when these ratios are perceived as balanced between partners, promoting mutual reciprocity and a sense of justice.Equity vs. Equality in RelationshipsEquity is distinct from equality. Fairness does not...

Self-Evaluation Maintenance Model01:29

Self-Evaluation Maintenance Model

383
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Area of Science:

  • Neuroeconomics
  • Cognitive Neuroscience
  • Decision Science

Background:

  • Neuroeconomics investigates brain mechanisms underlying value-based decision-making.
  • Context significantly modulates how individuals perceive value during choices.
  • Recent advances highlight the impact of context-dependent perception on valuation and choice.

Purpose of the Study:

  • To elucidate how context-sensitive value coding influences decision-making processes.
  • To explain choice set effects, differential gain-loss perceptions, and expectancy effects within a contextual framework.
  • To integrate behavioral and neural findings on context's role in valuation.

Main Methods:

  • Review of neuroeconomic studies on context and decision-making.
  • Analysis of behavioral data demonstrating context-dependent valuation.
  • Examination of neural correlates of context-sensitive value coding.

Main Results:

  • Context-sensitive value coding explains choice set effects.
  • Context influences the perception of gains and losses.
  • External economic signals' expectancy effects are modulated by context.

Conclusions:

  • Context plays a crucial role in shaping value representations in the brain.
  • Understanding context-dependent valuation is key to explaining complex decision-making.
  • Neuroeconomics provides a framework for understanding how context impacts economic choices.
