PSY 303 MIDTERM
CHAPTER 8 ANXIETY DISORDERS AND OBESSIVE COMPULSIVE DISORDER
-anxiety disorder
-generalized anxiety disorder GAD
-social anxiety disorder SAD
-panic attack
-anxiety: is the fear of what might happen
-fear and anxiety involve high-level as well as primitive brain processes
-research suggest that anxiety should be seen as developmental problem involving both
environmentl and genetic factors
-limbic system processes respond to stimuli in their own.
Cognitive Processes in Anxiety:
• Evolution of fear mechanisms.
• Cognitive bias.
• Stroop test : sari renk gosterip yesil yazma testi , cognitive biasta kullaniliyor
• Anxious individuals focus on negative
Developmental Aspects of Anxiety
• Factor increasing level of fear.
• Influence on popularity and social competence.
• Anxiety more prevalent among adolescents. #
• Rates higher than mood disorders
Models of Anxiety Development
• Role of genetics, epigenetics.
• Fear learnt from family and culture.
Seperation Anxiety Disorder:
- show distress when seperated from their caregivers
-processes an children develop independence and the abiliy to function on their own
-at least 4 weeks
treatment: to recognize anxious feelings when they occur
Generalized Anxiety Disorder:
-anxiety leads to four behaviors:
1. avoiding activities that can have negative outcomes
2. overpreparation for activities that can have negative outcomes
3. marked procrastion behvaviors due to wworries
4. repeatedly seeking reassurance
Treatment: cognitive behavioral approaches
-mindfulness
-medications such as benzodiazepines with psychotherapy
Social Anxiety Disorder:
concerned about meeting someone or about giving a talk in front of a group
treatment: CBT, exposure therapy, social skills training
Agoraphobia: in which person experinces fear or anxiety when in public
- age onset: 21-23
- diagnose in relation to panik disorder
- CBT approaches, antideprants effective
Specific Phobia: in which an individual experinces fear or anxiety about a particular situation or
object ( snakes,spiders..)
Panic Disorder: intense feeling of apprenshion,fear or anxiety
peak in first 10 min
often seen comorbid with agoraphobia
Obessive-Compulsive Disorder:
- may be autogenous or reactive
- obsessions are generally unwelcome thoughts that come into ones head
- compulsive are the behaviors one uses to respond to these thoughts
•
•
•
•
Hoarding disorder : excessive aquisition of objects and an initabbility to discard
these objects
Body dysmorphic disorder : preoccupation with a perceived flaw in ones physical
apperace
Trichotillomania.
Excoriation or skin picking.
Treatment for OCD
•
•
•
Most common medications : clomipramine ,trylic antideprseants
Exposure and response prevention
Prolonged exposure to feared thoughts.
Deep brain stimulation.
EATING DISORDERS CHAPTER 10
FEEDING DISORDER:
PICA

is a feeding disorder in which the person eats something that would not be
considered food.( clay,cornstrach,characol,newspaper..) nonnuntrive substances
 eating behavior have leasted for longer than 1 Month
 it leads to health problems
RUMINATION DISORDER
 -is when a person regurgitates his food (Yiyeceklerin yutulduktan sonra tekrar
ağza getirilmesini ve yeniden yutulmasi)
 -the swallowed food is then rechewed or spit out
 -must occur more then 1 month and not any part of any medical or eating
disorder
 -can result: halitosis ,, malnutrition,electrolyte,imbalance, dental problems
AVOIDANT/RESTRIVTIVE FOOD INTAKE DISORDER
 -is when an individual does not eat certain foods, which leads to such conditions
such as weight loss or nutritional deficieny
 -common in children 2-3 years , this Is referreed to as the Garcia effect or one trial
learning
THE PROBLEM OF OBESITY:
 Thrifty gene hypothesis: suggest that times of scares food sources helped shape
our genetic makeup
 evolutionary history may have us seeking substances that do not lead to a healthy
lifestyle ( for example sugar was not easy to come by )
 environmental facts-> family,culture,towns
 psychological facts-> self-esteem, need for comfort
 biological facts ->genetic makeup
 a homeostatic system regulates the body weight
 brain processes involving the limbic system that encode the reardinf aspect of food
intake along with emotional and cognitive aspect-> these brain processes lead to
overconsumption of food even when the person feels full
 drug addiction and obesity involve discruption in the dopamine pathways of the
brain
 brain processes involving the limbic system encoding the rewading aspect of food
intake along with emotional and cognitice aspects. obesity , like drug addiction
involves the distruptions in dopamine pathways
 these pathways modulate behavioral responses to environmental cues
 food and drug, psychological processes interact in a complex manner -> when we
see food or drug we like there are memory (hippocampus) , emotional (amgydala),
arousal ( thalamus), cognitive control (prefrontal cortex PFC) as well as autonomic
nervous system reactions related to consuming






intake food or drugs: cognitive system, a dopamine reward system, energy system
Psychological stress increases our consumption of food and weight gain
BRAIN MECHANIMS RELATED TO THESE SYSTEMS ARE CHANGEABLE EVEN IN
ADULTHOOD -> as environmental conditions change,metabolic brain circuits
change in relation to eating
BMI: body fat based on a persons height and weight
health problems: hypertension, dyslipidemia, diabetes,stroke,coronary heart
diseases,sleep apnea, some cancers , DEPRESSION
Differences in the View of Ideal Weight Between Males and Female
THE MAJOR EATING DISORDERS
->anorexia nervosa, bulimia nervosa, binge eating
disorder developmental pattern symtomps such as weight preoccupation, body dissatisfaction,
disordered eating
- partial genetic component -cultural component
ANOREXIA NERVOSA
two subtypes: the restricting type & binge eating or purging type
-food refusal, onset in adolosence, lack of concern about the consequences of not eating
charactericts:
-
-onset and consistency
-distorting body image
-lower than normal BMI
Neuroscience: - brain imaging of three components:
o the perception component: showed difrrences in the purcuneus and the interfior
partieal lobe
o the affective component: involved in PFC, the insula, the amgydala
o the affective and cognitive component: involved in amgydala, parietal lobe, prefrontal
lobe
-Gut bacteria: are involved in the emotionalty and eating patterns of those with eating
disorder. can influence in how medications affect you , may reduce the effect
Causes:
-Suggestive risk factors( familial,biological factors, psychological factors, behavior,
cultural,stressful life events)
-genetic -> twin studies suggest that both anorexia and bulimia can accounted by genetics.
-reduction of brain metabolism -> frontal,cingulate,temporal,partieal areas
-cultural factors: western culture
Treating anorexia:
-deny and not wanting to be treated
-familiy therapy: family based therapy is refereed to Maudsley approach( 3 phases:1. weight
restoration, 2.adolesecene take more control, 3.emphasizes developing healthy identity)
-Cognitive behavioral therapy: help the person develop productive thoughts and feelings
around his or her eating and view of self
BULIMIA NERVOSA
(1) binge eating in which person consumes large amounts of food
(2) purging where a person eliminates food from the body by such vomiting ,taking laxatives,
diuretics, enemas
(3) a psychological aspect in which ones self worth is seen in relation to ones weight or
bodyshape
-periods of overeating , out of control
-self induces vomiting or takes laxatives or medications to eliminate food , overexercise
compared with anoriexia: Body Weight NORMAL
-purging
-can lead to medical problems(menstrual disturbance,dental erosion, ..)
causes:
-genetic, cultural factors, differences in anxiety,self-esteem,sexual abuse
Treatment:
-Cognitive behavioral Therapy , Antidepressant medications
BINGE EATING DISORDER
-consumption of large amounts of food without purging
-higher in overweight individuals
Treating:
-
-Cognitive behavioral therapy
Goals of treatment , Psychosoical and other approaches,
drug treatments(show limited evidence of success)
DISSOCIATIVE DISORDER ch. 9
 is a loss of the normal intergration of cognitive functioning. this includes the persons
self, autobiographical memory, a sense of control and agency, intergrated awareness
of functioning
 Pathological dissociative symtoms: normal integration of consiuness,memory,
identity, perception
Depersonalization -> is the perception of not experiencing the reality of one’s SELF
Derealization -> is the experience that the world is not solid
 individuals with depersonalization disorder showed reduced autonomic responses to
unpleaseant stimulu. Inhibitory responses to negative emotional info
Dissociative Amnesia -> is an inability to recall important autobiographical info
Dissociative Fugue -> unexpected travel away from ones home or place with an inability
to recall ones past
 unable to remember their historical experience,
 procedural memory; is not lost nor is the ability to create ne long-term memeories
Dissociative identity disorder DID
 multipe personality disorder, there is a large amount of misinformation concerning
its existence
 current views it is less a disorder of multiple personalities
 experience different ‘personlaties’ at different times
 distruption in memory; (1) the person may not remember significant parts of his or
her life (2) the person may not remember how to perform an act or well learned skill
such as driving (3) the person may discover evidence of actions that he or she does
not remember doing
 Neuroscience research related to DID compared with other disorders, the volume of
the hippocampus and amgydala was studied with MRI , those with DID hat a smaller
volume compared with healthy control group
Treatment:
-
dissociative amenisa : solve on their own
long term treatment /long term psychopatherapy
no established medications
SEXUAL DISORDERS, PARAPHILIC DISORDERS, GENDER DYSPHORIA ch 11
Sexuality; more then the sexual experience; a central being human encompasses
sex, gender identities and rolea,sexual orientation,eroticism,
pleasure,intimacy,reproduction
Historical perspectives:
-depiction in paintings and carvings
-in some cultural seen as a negative force
-charles darwin: the manner in which sexual selection and self preservation were
important
-Sigmund freud: emphasized the way in which sexuality was imoortant for driving
force in humans
- Alfred kinsey: survey focused on 6 outlets of sexual orgasm: masturbation,
petting, nocturnal dreams, heterosexual coitus, homosexual behaviors, bestiality
Sexual desire, arousal, response
-desire for sex
-distinct processes: psychsiological sense to refer to the internal experience of
both cognitive and emotional processes
measaurement : electrocephalogy EEG , functional magnetic resonance imaging
fMRI
Your brain and Sexual Activity
- brain imaging studies-> cortical measures of arousal in addition to selfreport and blood flow changes in sexual organs
- Ferettis study: the processing of sexual arousal engages coplex brain
networks involving cognitive, emotional and self-processes
eye tracking: measure when a person looks when viewing stimuli in real time
Masters and Johnson: identified four phases of human sexual response:
(1) excitement -> blood flow is increased in genital region, increased muslc
tension
(2) plateau -> pleasurable internal experience continue, increase in heart rate
and breathing
(3) orgasm-> muscular contractions in the male cause the sperm to be released
(4) resolution -> return to pre-arousal,
SEXUAL DYSFUNTION DISORDERS
 causes significant distress or impairment
 3 perspectives -> medical and biological factors, psychological ,
relationship itself
Erectile Disorder -> (1) cannot obtain an erection during sexual activity
(2) cannot maintain an erection to completion of sexual activity
(3) decrease in rigidity of penis in a way interferes with sexual activity
Female Orgasmic Disorder -> the condition in which a woman either does not
experience an orgasm
Delayed Ejaculation -> the situation in which a male shows an unwanted delay of
ejaculation
Early Ejaculation-> an ejaculation approx. in the first min of sexual activity
(premature ejaculation de traditionally called)
Female Sexual Interest/Arousal Disorder -> reduction or absence of interest in
sexual activity
Male Hypoactive Sexual Desire Disorder -> male has little desire for sexual
activity
Genito-Pelvic Pain/Penetration Disorder -> pain, fear, anxiety during sexual
activity

Gender Dysphoria
Gender roles: one’s culture in terms of the kinds of activities boys and girls are
expactedt to engage
Gender Identity: internal experience of knowing that you are male or female
Gender Dysphoria: may have born as one gender in terms of their body, but the
internal experience is that of the other gender. Dysphoria is defined as a sense of
unease or suffering
Gender Dysphoria can be seen in children, adolescents, adults
Diagnosis in Children: at least 6 months present , at least 6 of 8 criteria must be
present
Diagnosis in adolescents and adult: 6 months duration of significant distress ,
impairement in social , also 2 of 6 criteria must be present
Transgender-> who have the anatomy of one sex and the gender identity of the
other
Transsexual -> transgender individual medical intervention such as hormone
treatment and gender-affirming surgey to change the body
The Brain and Gender Dysphoria
Amsterdam cohort : brain activity and structure in transgender adolescents more
closely resemebles typical activation patterns of their desire gender
white matter fiber pathways: who experienced themselves as male did indeed
look similar to those non-dysphoric individuals who were anatomically male

SUBSTANCE – RELATED & ADDICITIVE DISORDERS CH 12
Drug use in the United states
- -change in attitude toard drug use
- -changes in worldwide drug use
- -prohibition and laws against drugs
Substance Abuse, Dependence and Addiction
disordered use-> causes impairment or distress
intoxication -> effects of substance
withdrawal -> symptoms experienced when the substance is no longer used
3 major components to dependence:
(1) the desire to seek and take a certain substance
(2) the inability to avoid or limit the intake of the substance
(3) the experience of negative emotional states when the substances is not
available
Who becomes addicted?
• -timing of use ( 15 yasdan once baslayinca daha olasik)
• drugs affect adolescents in a different manner than they do adults
• drugs have direct influence on the frontal lobe
Genetic , environment , evolutionary influences
• -genetic factors
• environmental factors such as stress and low socioeconomic levels,
epigenetics
• social well-being
Pattern of Addiction
(1) intoxication
(2) bingering
(3) withdrawal
(4) craving -> losing control to limit intake
-increased tolerance
-emergence of negative emotional state
-rewarding effect of drugs is based on their ability to increase dopamine , the
mesomblic dopamine system
Can Drugs change your brain?
- YES
- Pathways connect with the nucleus accumens prefrontal cortrxx, dorsal
striatum, amgydala
- dopamine is releseade in these structures -> reward or pleasure
- molecular mechanisims of many drugs leave excessice dipamine
availbe in the brain
- cocaine BLOCKS dopamine uptake in the synpase or increases
dopamine
- Nictone,alcohol,stimulants, marijhana all increase dopamine in the
dorsal stratum abd ventral s
- disruption of prefrontal cortex
-Drug addiction can be seen as a form of enhanced motivation
ALCOHOL
alcohol use -> intoxication and withdrawal
