Reason and Intuition01:37

Reason and Intuition

6.9K
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

247
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...

Cognitive Learning01:21

Cognitive Learning

668
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Decision Making: Traditional Method01:14

Decision Making: Traditional Method

4.2K
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...

Decision Making: P-value Method

5.7K
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...

Higher Mental Functions of Brain: Learning and Memory01:26

Higher Mental Functions of Brain: Learning and Memory

976
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Area of Science:

  • Animal Behavior
  • Neuroscience
  • Cognitive Science

Background:

  • High-speed decisions often rely on heuristics, trading accuracy for speed.
  • Archerfish exhibit rapid, accurate prey capture using ballistic fall predictions.
  • The flexibility of such fast decisions remains largely unexplored.

Purpose of the Study:

  • To investigate the flexibility of archerfish high-speed decision-making.
  • To determine if archerfish can adapt their decision rules to novel conditions.
  • To explore the cognitive mechanisms underlying rapid, adaptive behavior.

Main Methods:

  • Developed a system to alter the predictive rule for prey landing points.
  • Tested adult archerfish's ability to adapt to new rules.
  • Assessed generalization to untrained scenarios and dual-rule application.

Main Results:

  • Archerfish successfully reprogrammed their high-speed decision to a novel rule.
  • Fish immediately generalized the new rule to untrained situations.
  • The decision circuit demonstrated abstraction and simultaneous use of distinct rules.

Conclusions:

  • Archerfish exhibit unexpected cognitive flexibility in high-speed decision-making.
  • This challenges the notion of an inherent speed-accuracy trade-off in rapid decisions.
  • High-speed decision-making systems possess significant adaptive potential, often underestimated.
