AO1:

(GENETICS) WHETHER SOMETHING HIS HEREDITARY. SOME PHOBIAS ARE DANGEROUS (SPIDERS/SNAKES) BEEN SAID THAT PEOPLE HAVE EVOLVED INTO DEVELOPING A GENETIC PRDISPOSITON FOR THE SURVIVAL ASPECT (PREPERDNESS THEORY)

EXPLAIN WHY PEOPLE DEVELOP PHOBIAS WITHOUT HAVING EVER HAD A BAD EXPERIENCE.

(NEUROLOGICAL) GABA- PEOPLE WHO DEVELOP PHOBIAS ARE THOSE WHO HAVE A HIGHER LEVEL OF PYSIOLOGICAL AROUSAL AND AND MORE SENSITIVE TO EXTERNAL ENVIRONMENT. 

AMYGDALA- EMOTION CONTROL CENTER IN THE BRAIN, IS ACTIVATED IN RESPONSE TO A PERCIEVED THREAT. BRINGS IN A PSYCHOLOGICAL ASPECT (BIO-PSYCHOLOGY)

SEROTONIN- PEOPLE WITH HIGHER LEVELS OF SERETONIN ARE MORE LIKELY TO DEVELOP A PHOBIC DISSORDER, HIGH LEVELS OF DOPAMINE, MEANS YOU'RE MORE RELAXED, SO LESS LIKEY TO DEVELOP A PHOBIC DISSORDER.

AO2:

(NEUROLOGICAL) LADDER AND MATTHEWS- HIGH LEVELS OR AROUSAL ARE MORE SIGNIFICANT IN AGRAPHOBIA AND SOCIAL PHOBIA, CONDITIONING WAS MORE SIGNIFICANT IN SPECIFIC PHOBIAS.

(GENETICS) FAMILY- EXAMINES RECURRANCE OF A PARTICULAR DISORDER BETWEEN AND WITHIN GENERATIONS. HOYES FOUND HIGHER RATE OF AGRAPHOBIA AND PANIC DISORDER IN FIRST DEGREE RELATIVES. 

TWIN- EXAMINES RATE OF CONCORDANCE OR A DISORDER, COMPARISONS MADE BETWEEN MZ TWINS AND DZ TWINS. TOGERSON FOUND 31% CONCORDANCE IN MZ TWINS FOR PANIC DISORDER AND AGRAPHOBIA VS 0% WITH DZ TWINS. 

ADOPTION VS TWINS IS AN ATTEMPT TO SEPERATE GENETIC FROM ENVIRONMENTAL FACTORS.

AO3:

(NEUORLOGICAL) MISINTERPRETATION CAN LEAD TO MISDIAGNOSIS, BIOLOGICALLY DETERMINISTIC, REDUCTIONIST, PET SCANS CAN DEVELOP MORE DISORDERS WHILST TRYING TO GET RID OF ONE(CLAUSTRAPHOBIA) EITHICS WITH BLOOD TESTS BAIN SCANS, (DISTRESS) CAUSE AND EFFECT IS INCONCLUSIVE, SCIENTIFIC AND OBJECTIVE.

BETTER THAN MOST APPROACHES FOR CLASSIFICATION SYSTEMS, AS THEY WOULDNT BE HERE WITHOUT THIS APPROACH, UNDERPINNED. 

(GENETICS) INTERVIEWS ARE RETROSPECTIVE, SUBJECTIVE, SOCAILLY DESIRABLE, DEMAND CHARACTERISTICS, AND ADOPTIVES MAY NOT WANT TO TALK ABOUT THINGS. 

NATURE VS NURTURE, SUPPORTS NATURE BUT FAMILT STUDIES (ENVIRONMENT) MAY SHOW NURTURE AS WELL AS ADOPTION.SELF FUFILLING BEHAVIOUR 'IT RUNS IN THE FAMILY' (MANUFACTURED) FEAR AND ANXIETY ARE ALREADY PART OF THE GENETIC MAKEUP. FAMILY- MOST LIVED IN SAME ENVIRONMENT.

LINK PSYCHOLOGICAL APPROACHES :PSYCHODYNAMIC, COGNITIVE, BEHAVIOURIST.
