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...
The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

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 $2,000...
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...
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...
The Availability Heuristic01:08

The Availability Heuristic

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

Extra-target information, often dismissed as irrelevant, is crucial for efficient attention. These signals reduce uncertainty and guide goal-directed attention, acting as cognitive shortcuts for faster information processing.

Area of Science:

  • Cognitive psychology
  • Neuroscience
  • Attention studies

Background:

  • Goal-driven attention typically focuses on selecting task-relevant information.
  • Extensive research reveals attentional selection is influenced by numerous "task irrelevant" sources.
  • These external signals often carry uncertainty-reducing information.

Purpose of the Study:

  • To systematically review sources of extra-target information that reduce uncertainty.
  • To argue that "irrelevant" information is both relevant and necessary for efficient environmental processing.
  • To demonstrate the integral role of "irrelevant" information in rapid, goal-directed attentional processing.

Main Methods:

  • Literature review and synthesis of existing research on attentional mechanisms.
  • Analysis of studies demonstrating biases in attentional selection.
  • Examination of evidence for uncertainty reduction and target prediction from extra-target cues.

Main Results:

  • "Irrelevant" information sources provide target-predictive signals.
  • These signals are integral to efficient goal-directed attentional processing.
  • Extra-target information acts as cognitive shortcuts, enhancing environmental information selection.

Conclusions:

  • "Irrelevant" information is essential for effective attention and environmental processing.
  • Attentional mechanisms leverage external cues to optimize information selection.
  • Understanding these "shortcuts" is key to comprehending cognitive efficiency.
