Term
| what are the fucntions of the threat evaluation system? |
|
Definition
Threat assessment and response:
Detection;
Discrimination;
Rapid, coordinated response; Return to baseline;
Memory function |
|
|
Term
|
Definition
External stimuli (exteroception)
and
Internal stimuli (interoception) |
|
|
Term
| how do you look for external stimuli? |
|
Definition
Sensory systems - the 5 senses
Precise, but limited in range |
|
|
Term
| how do you look for internal stimuli? |
|
Definition
| proprioception (less precise) and visceral sensations (interal) (imprecise) |
|
|
Term
| What is the point of discriminatin? |
|
Definition
Sort relevant from irrelevant stimuli:
Relevant (Threatening vs. Desirable);
Novel versus known;
Harmful versus benign |
|
|
Term
| what are rapid and coordinated responses? |
|
Definition
Conscious attention & appraisal
(Pre-emptive processing);
Automatic behaviors
(Innate;
Learned;
(Conditioned;
Practiced;))
Autonomic support |
|
|
Term
| After a threat response, how do you return to baseline? |
|
Definition
Through de-escalation: Conscious decisions;
Contingencies - reward/punishment;
Automatic behaviors
Time limited - habituation;
Autonomic support
Homeostasis - negative feedback |
|
|
Term
| why do you return to baseline? |
|
Definition
| threat responses are not sustainable |
|
|
Term
| how does memory help threat? |
|
Definition
Enhance effectiveness of future responses:
Change detection sensitivity;
Improve recognition of threats;
Modify innate and automatic responses;
Speed recovery |
|
|
Term
| what is biologicall involved in anxiety? |
|
Definition
Stress response:
Locus ceruleus
(Noradrenergic, sympathetic activation)
Limbic system (Papez)::
Hippocampus - thalamus - cingulate
Integrated system:::
Prefrontal cortex (PFC)
Central nucleus of the amygdala (CNA) |
|
|
Term
| What causes behavioral inhibition? |
|
Definition
Timidity and withdrawal in novel situations;
Exaggerated autonomic & HPA responses;
Slow habituation |
|
|
Term
|
Definition
| corticotrophin releasing factor |
