Interoception

Question 1

what is interoception

Answer 1

sense that allows us to perceive the internal state of our body
involves the ability to detect and interpret signals originating from within
e.g. hunger, thirst, heart rate, respiration, body temperature, pain, etc

Question 2

homeostasis

Answer 2

interoception supports homeostasis
homeostasis: the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes

Question 3

allostasis

Answer 3

efficient regulation required to prepare the body to satisfy its needs before they arise
predictive NOT reactive (like homeostasis)

Question 4

example of homeostasis

Answer 4

sweating to cool the body when overheated
(reactive to body states)

Question 5

example of allostasis

Answer 5

brain increases blood pressure and cortisol in the morning to get you ready to wake up and move

Question 6

classic definition of interoception

Answer 6

afferent processing of signals originating within the body and which refer to the state of the body
generated by mechanorecpetive organ-stretching and chemoreception
transmitted by afferent pathway

Question 6

what does interoception NOT include according to the classic definition

Answer 6

-proprioception (skeleto-motor and vestibular information)
-sensing the environment

Question 7

anatomical-functional definition of interoception

Answer 7

the sense of the physiological condition of the body at any given time
carry information relevant for homeostatic control, including some information conveyed through exteroceptive channels

Question 8

interoceptive hierarchy

Answer 8

-afferent signal
-preconscious impact of afferent signal
-interoceptive accuracy
-interoceptive sensibility
-interoceptive awareness
-executive/ attribution

Question 9

afferent signal

Answer 9

actual physiological signals coming from the body

Question 10

preconscious impact of afferent signal

Answer 10

preconscious influence that physiological signals have in cognition and behaviour

Question 11

interoceptive accuracy

Answer 11

ability to correctly identify interoceptive sensations

Question 12

interoceptive sensibility

Answer 12

subjective beliefs about interoceptive accuracy or attention

Question 13

interoceptive awareness

Answer 13

meta-cognitive awareness of interoceptive accuracy

Question 14

execution/ attribution

Answer 14

interpreting causes of interoceptive sensations and acting upon them
