Optimal Foraging00:48

Optimal Foraging

14.2K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Decision Making: Traditional Method

5.6K
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Reason and Intuition

7.6K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Decision Making01:20

Decision Making

1.2K
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

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...

The Availability Heuristic01:08

The Availability Heuristic

7.2K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Summary
This summary is machine-generated.

This study reveals that people actively manage information sampling in decision-making. Cognitive processes, like tracking uncertainty, guide how we gather evidence from different sources.

Area of Science:

  • Cognitive Psychology
  • Decision Science
  • Perception

Background:

  • Understanding active information sampling is crucial for decision-making models.
  • Previous research often assumes passive information intake, not active foraging.

Purpose of the Study:

  • To test an information foraging framework for active visual sampling behavior.
  • To characterize mechanisms driving information gathering in multi-source decision problems.

Main Methods:

  • Experiments involved participants making judgments about motion direction from random dot patterns.
  • Sequential sampling from multiple information sources was analyzed.
  • Participants' visual sampling strategies were observed.

Main Results:

  • Information accumulation reached an asymptote dependent on source quality.
  • Sensory evidence was unequally weighted, favoring early samples.
  • Information loss was minimal when switching between sources.
  • Switching behavior was guided by online monitoring of uncertainty.

Conclusions:

  • Perceptual decision-making involves active cognitive control over sampling.
  • Individuals monitor and utilize uncertainty to guide information gathering.
  • This supports a dynamic, controlled approach to foraging for perceptual evidence.
