Reason and Intuition01:37

Reason and Intuition

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 brain can only use...
Decision Making01:20

Decision Making

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: Traditional Method01:14

Decision Making: Traditional Method

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...
Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...
High-Level and Low-Level Awareness01:19

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
Subconsciousness and No Awareness01:15

Subconsciousness and No Awareness

The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Area of Science:

  • Cognitive Psychology
  • Computational Neuroscience
  • Decision Making

Background:

  • Current decision-making models often overlook the interplay between intentional and stimulus-driven processes.
  • Efficient cognitive function requires adaptability to novel information.
  • Understanding the interaction between different decision systems is crucial for comprehensive models.

Purpose of the Study:

  • To investigate the interaction between intentional and stimulus-driven decision processes.
  • To develop and validate a new computational model accounting for this interaction.
  • To explore how participants adjust perceptual decisions based on new, unpredictable information.

Main Methods:

  • Behavioral experiments involving participants anticipating and responding to stimuli with variable delays.
  • Development of a two-stage computational model with independent initial processing and interactive second-stage processing.
  • Testing the model's ability to explain behavioral data, including conditions with response bias.

Main Results:

  • Participants successfully adjusted their initial decisions when new information arrived early.
  • The proposed two-stage model accurately captured behavioral adjustments and effects of response bias.
  • Model results align with physiological findings suggesting parallel and interactive processing.

Conclusions:

  • Cognitive decisions are adaptable, integrating novel information effectively.
  • The developed two-stage model provides a framework for understanding the interaction between intentional and stimulus-driven systems.
  • Both parallel and interactive processing are vital in natural decision-making, with a critical transition point identified.
