Convenience Sampling Method00:55

Convenience Sampling Method

10.5K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Optimal Foraging

12.8K
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.

Sampling Plans

606
Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Stratified Sampling Method01:16

Stratified Sampling Method

14.0K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a stratified sample, divide the population into groups called strata and then take a...

The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.6K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Summary
This summary is machine-generated.

Simple choices are guided by visual attention, which dynamically samples information from options with high value and uncertainty. This optimal information sampling strategy explains fixation patterns and decision-making in simple choices.

Area of Science:

  • Cognitive Science
  • Neuroscience
  • Decision Science

Background:

  • Simple choices involve integrating noisy evidence over time.
  • Visual attention fluctuations can significantly impact decision-making outcomes.
  • The determinants of visual fixation patterns during choice remain unclear.

Purpose of the Study:

  • To model the decision process for simple choices as an information sampling problem.
  • To determine the optimal policy for sampling information during choice.
  • To investigate how value estimates influence fixation and choice behavior.

Main Methods:

  • Developed an information sampling model for simple choice tasks.
  • Approximated the optimal sampling policy within this model.
  • Analyzed fixation and choice data in binary and trinary choice scenarios.

Main Results:

  • Optimal information sampling involves focusing on options with high value and high uncertainty.
  • The derived optimal policy accurately predicts fixation patterns in simple choices.
  • The model accounts for differences in choice behavior between binary and trinary options.

Conclusions:

  • Fixation during simple choice is dynamically driven by evolving value estimates.
  • Decision-making processes align with principles of optimal information sampling.
  • Understanding attention-value dynamics is key to explaining choice behavior.
