Schemas

11.6K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Natural Selection and Adaptation01:15

Natural Selection and Adaptation

212
Natural selection, a fundamental concept in evolutionary biology, is the mechanism by which evolution is driven, favoring organisms that are best adapted to their environments. This process enhances their chances of survival and reproduction. Adaptation, a key outcome of this process, involves genetic modifications that optimize an organism's functionality under specific environmental challenges, such as extreme cold or thinner air at high altitudes.
Beyond physical adaptations,...

Nonconscious Mimicry

4.6K
Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Social Facilitation01:04

Social Facilitation

32.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Deindividuation00:57

Deindividuation

26.4K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Evolutionary Psychology01:20

Evolutionary Psychology

274
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Computational Biology

Background:

  • Survival necessitates rapid decision-making under threat with minimal error.
  • This presents a significant computational challenge for the brain.

Purpose of the Study:

  • To investigate the computational mechanisms underlying human escape decisions.
  • To model how the brain rapidly solves survival challenges.

Main Methods:

  • Utilized fully immersive virtual reality with 13 natural threats.
  • Examined escape decisions in 59 human participants.
  • Conducted perturbation experiments to test decision algorithm properties.

Main Results:

  • Escape decisions dynamically update based on environmental changes.
  • Decisions integrate time-to-impact, threat characteristics, predicted trajectory, and personal traits.
  • The decision algorithm demonstrates planning capabilities and can incorporate novel actions.
  • Information-seeking and foraging suppression show limited devaluation sensitivity.

Conclusions:

  • Human escape decisions are not hardwired but arise from a flexible computational architecture.
  • This research provides foundational steps toward a computational model of rapid survival decision-making in the human brain.
