	 	 	 	 V Body	Language 	&	Behavior 	 Body	language	is	a	science	of	understanding	human	behavior. 	It	presents many	variables,	and	differs	from	culture	to	culture,	and	person	to	person. 	Be wary	of	people	and	their	differences. 	Understand	that	context	is	also	necessary. In	one	situation,	a	woman	playing	with	hair	may	come	across	as	flirty,	but	it another,	it	may	indicate	she	is	nervous	or	even	annoyed. 	However,	there	are some	forms	of	body	language	that	are	considered	universal,	and	some	tactics	that humans	know	instinctively,	such	as	the	pacifying	behavior,	which	will	be discussed	below. The	area	of	the	brain	that	controls	our	reactions	to	the	world	around	us	is called	 the	limbic	system. 	It	is	considered	to	be	the	honest	part	of	the	brain. 	The section	in	which	we	reason	and	negotiate	is	the	neocortex,	and	is	responsible	for our	ability	to	lie. 	A	human's	ability	to	communicate	nonverbally	comes	from	the limbic	system,	so	naturally	it	is	much	easier	to	trust	and	may	help	in	the detection	of	lies	and	honest	feelings. There	are	essentially	two	categories	of	cues	in	the	world	of	nonverbal communication	conveys:	comfort	and	discomfort. 	Comfort	may	include emotions	such	as	happiness,	relaxation,	and	elation,	for	example. 	Discomfort may	include	unhappiness,	anger,	stress,	nervousness,	disgust,	and	annoyance. Just	as	in	any	form	of	communication,	isolated	signs	are	rarely	helpful. Humans	verbally	communicate	with	one	another	not	through	unrelated	and isolated	words,	but	in	sentences. 	This	applies	to	body	language	as	well. 	Look	at the	bigger	picture. 	Look	at	your	subject's	face,	arms,	legs,	general	posture, position	in	relation	to	others,	and	so	on,	in	order	to	ensure	you	are	collecting	a sufficient	amount	of	“words”	to	put	together	a	“sentence”. 	The	best	and	most accurate	deductions	are	the	ones	that	have	the	most	evidence,	and	this	applies not	only	to	body	language,	but	to	any	subject	from	which	you	will	attempt	to
