Understanding Peripersonal Space and its Importance in Human Interaction
TLDR Peripersonal space is the area around a person that they can physically interact with and is related to our understanding of how we are built and move through the world. It is divided into different distances and can be influenced by factors such as tools, cultural differences, and personal comfort levels.

The podcast episode is about peripersonal space and how it is the area around a person that they can physically interact with.
05:12
Peripersonal space is the area where we physically interact with reality and is related to body schema, which is our understanding of how we are built and how we move through the world.
10:53
Peripersonal space is not binary, but rather divided into gradients of grasping distance and walking distance, and it may have evolved from a need for self-defense.
16:12
Peripersonal space is divided into different distances, such as flight distance, defense distance, and critical distance, and is defined by the consistency of individuals within a species, with humans having a flight distance of zero.
21:49
The size and shape of peripersonal space (PPS) varies depending on the body part being studied, and there is a mechanism in place to prevent one PPS area from merging with another, according to researchers Rory Buffachi and Gian Domenico Ianetti.
27:38
The parapersonal space changes based on what tools are being used, and the use of tools can extend the parapersonal space of the body.
33:06
The brain treats tools differently than other objects and can adopt them as part of the body schema, as shown by studies with lasers, sticks, and rakes.
38:24
Anxiety, mood, cultural differences, spinal injuries, pregnancy, status, and claustrophobia can all affect the size of a person's peripersonal space.
44:05
Personal space, or proxemics, varies among individuals and cultures, but Americans tend to be more comfortable with closer physical proximity compared to other cultures.
49:44
Personal space varies among individuals and cultures, and it's important to consider different levels of comfort and cultural norms when interacting with others.
55:08
Mirror neurons and peripersonal space are closely related, as shown in a study with monkeys where the firing of mirror neurons increased when the person grabbing an object was closer to the monkey, but decreased when a clear barrier was put between them, indicating that the monkey's brain recognized the barrier and adjusted its perception of interaction with the object accordingly.
