What is allocentric spatial awareness?
Allocentric spatial transformations involve an object-to-object representational system and encode information about the location of one object or its parts with respect to other objects, while egocentric perspective transformations involve a self-object representational system.
What is allocentric navigation?
Allocentric navigation utilises external cues or landmarks in relation to each other to navigate and is independent of self (Figure 1B). An advantage of allocentric navigation is the flexibility of being able to locate novel points from various start locations as long as the external cues remain the same.
What is allocentric coding?
When a visual target is presented with neighboring landmarks, its location can be determined both relative to the self (egocentric coding) and relative to these landmarks (allocentric coding).
Are place cells allocentric?
Place fields are allocentric, meaning that they are defined with respect to the outside world rather than the body. By orienting based on the environment rather than the individual, place fields can work effectively as neural maps of the environment.
What is Psychocentric and allocentric?
Psychocentric tourists are self-inhibiting, nervous, and non-adventurous; they often refuse to travel by air for psychological reasons rather than financial or other practical concerns. In comparison, allocentric tourists are outgoing, self-confident, and adventurous.

What is spatial navigation in the brain?
Spatial navigation is a complex cognitive process based on multiple senses that are integrated and processed by a wide network of brain areas. Previous studies have revealed the retrosplenial complex (RSC) to be modulated in a task-related manner during navigation.
What is egocentric spatial understanding and what is allocentric spatial understanding which do infants have first?
Specifically, it is traditionally accepted the distinction between two types of “frames” used to represent spatial information: The egocentric frame, which includes spatial information about the location of the individual in the environment, and the allocentric frame, which involves the spatial information about the …
What part of the brain is associated with allocentric representations of space?
medial temporal lobe
Allocentric spatial coding has mainly been associated with the medial temporal lobe (MTL) and forms the basis for a cognitive map (Tolman, 1948) of the environment, from which information on the spatial relations of landmarks or objects can be flexibly extracted when needed.
What does Allocentric mean in tourism?
Allocentric (The Wanderers) − A tourist who seeks new experiences and adventure in a wide range of activities. This person is outgoing and self-confident in behavior. An allocentric person prefers to fly and to explore new and unusual areas before others do so.
What is spatial perception?
Spatial perception involves not one but many specific abilities. Within the visual domain these include locating points in space, determining the orientation of lines and objects, assessing location in depth, appreciating geometric relations between objects, and processing motion, including motion in depth.
How are spatial memory and egocentric strategies related?
Concerning spatial navigation, our results showed a preservation of egocentric strategies, along with specific impairments in the use of allocentric and switching abilities. Regarding spatial memory, instead, outcomes were more divergent and not frame-specific.
How does age affect allocentric and egocentric memory?
Aging does not affect egocentric navigational strategies, whereas allocentric and switching abilities show a gradual decline. A general age-related weakening of spatial memory has been observed, even if not frame-specific;. Executive functions may play a critical role in age-related spatial difficulties.
How is the allocentric frame supported in the hippocampus?
The allocentric frame is supported mainly by hippocampus place cells ( Ekstrom et al., 2003, O’Keefe and Dostrovsky, 1971, Ono et al., 1993 ), which fire in specific spatial locations independently from the subject’s orientation.
How does age affect your spatial reference frame?
A general age-related weakening of spatial memory has been observed, even if not frame-specific;. Executive functions may play a critical role in age-related spatial difficulties. Aging affects many aspects of everyday living, such as autonomy, security and quality of life.
