Reason and Intuition01:37

Reason and Intuition

7.4K
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...

Kruskal-Wallis Test01:19

Kruskal-Wallis Test

1.3K
The Kruskal-Wallis test, also known as the Kruskal-Wallis H test, serves as a nonparametric alternative to the one-way ANOVA, offering a solution for analyzing the differences across three or more independent groups based on a single, ordinal-dependent variable. This statistical test is particularly valuable in scenarios where the data does not meet the normal distribution assumption required by its parametric counterparts. Kruskal-Wallis test is designed typically to handle ordinal data or...

Reasoning01:30

Reasoning

414
Reasoning is the action of thinking about something in a logical, sensible way. It is integral to problem-solving, decision-making, and critical thinking. Reasoning can be inductive or deductive. Reasoning involves transforming information into conclusions, which is essential for problem-solving, decision-making, and critical thinking.
Inductive reasoning involves deriving generalizations from specific observations. This type of reasoning helps form beliefs about the world. For example,...

Deductive Reasoning

64.8K
Deductive reasoning, or deduction, is the type of logic used in hypothesis-based science. In deductive reasoning, the pattern of thinking moves in the opposite direction as compared to inductive reasoning, which means that it uses a general principle or law to predict specific results. From those general principles, a scientist can deduce and predict the specific results that would be valid as long as the general principles are valid.
For example, a researcher can deduce specific predictions...

Inductive Reasoning00:59

Inductive Reasoning

65.5K
Inductive reasoning is a form of logical thinking that uses related observations to arrive at a general conclusion. It is uncertain and operates in degrees to which the conclusions are credible. As such, inductive arguments can be weak or strong, rather than valid or invalid, and conclusions can be used to formulate testable, falsifiable hypotheses.
Inductive reasoning is common in descriptive science. A life scientist makes observations and records them. This data can be qualitative or...

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

366
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Human Agency Research

Background:

  • Traditional studies on intention use spontaneous movements, lacking ecological validity.
  • Spontaneous actions lack reasons to act and consequence evaluation, limiting generalizability to deliberate actions.
  • Deliberate actions are crucial for understanding human agency and free will.

Purpose of the Study:

  • To develop an ecologically valid tool for studying deliberate intended action.
  • To compare neural preparation of deliberate actions (using "Free Wally") with spontaneous actions.
  • To validate the "Free Wally" game as a controlled environment for intention research.

Main Methods:

  • Development of the "Free Wally" computer game for deliberate action.
  • Comparison of "Free Wally" with a traditional spontaneous action measurement game.
  • Real-time probing for intention timing.
  • Measurement of neural preparation via (lateralized) readiness potential and alpha/beta event-related desynchronization.

Main Results:

  • No significant differences were found in late stages of action preparation (readiness potential, event-related desynchronization) between the "Free Wally" game and the spontaneous action game.
  • This suggests "Free Wally" is a valid tool for studying neural correlates of intended action.
  • Differences in earlier intention formation stages are anticipated and warrant further investigation.

Conclusions:

  • The "Free Wally" game provides a controlled, ecologically valid environment for studying deliberate intended actions.
  • "Free Wally" is validated as a tool for measuring neural preparation in intended actions.
  • Further research is encouraged to explore intention formation and content using this novel tool.
