Is the motivation concious in Munchausen's by proxy? What is the order of loss or orientation? Pt autonomy vs. beneficence: when does autonomy win out? Who is usually the abuser in physical abuse in children? Do divorcees remarry frequently? How does alpha relate to the Type I error? Is divorce related to industrialization? Is HIV positivity a reportable disease? name reportable diseases? What factors influence the Power of a study? What is a Null Hypothesis? Define ego defenses. Is IQ testing more highly correlated with genetics or school achievement? What is the basic mechanism underlying all ego defenses? What type of behavior requires a continuous reinforcement schedule?

Thats a basket full! Also since there is no # Ill randomly answer 3. 1)HIV is not reportable but full blown AIDS is! 2)Ego defenses-UNCONSCIOUS mental operations that act to decrease anxiety, maintain an individuals sense of safety, equilibrium and self esteem. 3)At least 75% remarry within 3 years. This # is greater in men closer to 90%

#1-Id say in Munchausen by proxy the motivation IS conscious because it is categorized as a factious disorder. The patient presents signs and symptoms so well that he can gain admission to a hospital. #2-What is the order of loss or orientation???What does this q mean???????? #3 The abuser in child abuse is usually the closest family member/female (the mother)

#1-Continuous reinforcerment-response is quickly learned, least resistant to extinction[after every response] recieving soda from a vending machine #2-I.Q-strong genetic component. #3-null hypothesis: a)In laymans terms- Is a test statistically significant? b)In epidemiology-It has this name because in most of research it is the hypothesis for which there is no difference between samples being compared.(eg. a new drug produces no change compared ith a placebo.) c)mathematically-we could see something like this: "significant at p<or =.05 "--means that there is a 5% probability that the result could have been obtained by chance alone.

1)A type I error is also called an alpha error. Alpha is the same as the p value. A Type I error is when you reject the null hypothesis and it is infact true 2)Power of study(ability to detecta false null hypothesis) affected by I)an alpha increase II)the size in the difference in sample mean compared to the hypothesized population mean(known as the effect size) increase III)sampling error decreases IV)*Increasing sampling size-most important 3)Reportable disease-Ill name 2 HIV and Smallpox,can anyone name others?

mc reportable diseases are clamydae, ghonarhea, measles.... aids is reportable..hiv isn't. power of study is 1-b error.. factitious disorder and thereore munchausen are uncoucious (malingering is concious)... the difference between factition and somatization is that in somatifom d/o the patient actually has the symptoms... null hypo "this drug IS NOT effective" "These patients will NOT get better with treatment" if P is less than <.05 then it is an alpha error (type 1) and if it more than >.05 it is a Beta error (type 2)(though they could change the .05 cutoff in the stem they would have to tell you it). though you can figure out alpha from p you can't figure out beta from p (beta is 1-b=power)... Continuoous reinforcement is MOST likely to become extinct... (just thought i'd make his point more clear)..temper tantrums require continuous reinforcement so that you can eventually extinquish them...

I meant Aids is reportable (typo) Also I disagree-Continuous reinforcement (ie.getting paid for every shirt you sew) is least resistant to extinction And if a child throws a temper tantrum and the mom continuously give baby candy he will continue to throw a temper tantrum-Continuous reinforcement Id say Factious which includes Munchasens and Malingering,they are conscious simulation of physical illness for psychological or tangible gain but unconscious motivation From what I see if the p value is equal to or less the 0.05 it is unlikely that an alpha error has been made. Good discussion.

i agree with you on munchhausen.. (conciously doing it... but pt doesn't know why...) the most resistant to extinction is variable ratio reinforcement (like gambling..)... if a child is throwing a temper tantrums, you first put them on a continuous reinforcement schedule, and then stop so you have a better chance of extinction. most parents give in after the child throws a temper tantrum long enough and thus follow a variable ratio schedule, which is why it is so hard to get them to stop.... (aren't we saying the same thing.... least likely to be resistant to extinction is the same as most likely to become extinct?? if p is less than <.05 you have the chance of an alpha error, and if it is >.05 you have the chance of a beta error... the criterion (.05) is the cutoff point at which u can decide which error has been made. the lower the p is from .05, the less chance you made an alpha error
