After reading up on his biochemistry, Dr. Vapid thinks that vitamin P might be an effective treatment for schizophrenia. He recruits 124 carefully diagnosed schizophrenics and divides them into two groups. Group A receives a tablet containing 3.7 micrograms of Vitamin P every day and Group B receives a similar appearing placebo. The people who distribute the tablets do not know which is the placebo and which is the Vitamin P. After a fortnight, all the patients are evaluated on a battery of clinical tests. The results show no significant differences on any test between the two groups. Dr Vapid concludes that Vitamin P has no value for treating schizophrenia.
What MAJOR problem do you see what this conclusion?

Selecciona una de las siguientes respuestas posibles:

no real problem at all. This is a trick question.
He should have a control group of normal respondents
The sample is not large enough
Maybe the dosage level was too small for any effect to be noticeable.

Dr Zapp and her co-workers observe primary school children in seventeen randomly chosen New Zealand playgrounds. A year's intensive and reliable observation reveals that boys attack boys (defined as the clenched fist of a boy A coming into contact with boy B) significantly more often than girls attack girls. Dr Zapp concludes that New Zealand primary schoolboys are more aggressive than New Zealand schoolgirls.
What MAJOR problem do you see with this conclusion?

Selecciona una de las siguientes respuestas posibles:

No real problem at all. This is a trick question
The definition of aggression is probably too narrow
Maybe the co-workers are working to different definitions of aggression
She should be looking at what the children do in the classrooms

In 1976, Ulric Neisser claimed that cognitive psychology at that time had failed to address the everyday aspects and function of human behaviour, and he blamed this failure on the excessive reliance on artificial laboratory tasks that were widely used in cognitive psychology before the mid 1970's. This complaint can be summarised by saying that he thought the cognitive psychology of his time had flaws in:

Which of the following is an issue of external validity?

Selecciona una de las siguientes respuestas posibles:

A researcher in the USA finds that people who are primed with money are more selfish and more independent than controls, but this relationship is not found in NZ or Poland
A researcher in the USA investigating whether priming with money increases selfishness finds that the result holds when the experiment is run by assistant James but not when it is run by Bill.
A researcher in the USA investigating whether priming with money increases selfishness finds that the result of her experiments differ with the type of statistical test (t or Mann-Whitney U) that is used to examine the difference.
A researcher in the USA investigating whether priming with money increases selfishness finds that those who are primed are less likely to help others pick up fallen possessions but more likely to give charitable donations.

Which of the following is true for quasi-experiments?

Selecciona una de las siguientes respuestas posibles:

If you are looking at the effect of a real-world change it is necessary to identify the change before it happens.
Actually there does not have to be a real-world change at all. Instead the researcher can rely on finding natural variation in the independent variables. ( so, for example, if we were looking at the effects on traffic laws on the accident rate, we could make use of the fact that different societies have different traffic laws.)
Often in quasi-experiments the real-world change does not occur in an instant but is spread over time.
The researcher has to have some control over the timing of the real world change.

Deborah is interested in how people's tendency to take risks varies with their age, sex, and income. She takes a random sample of New Zealanders over the age of 18 and measures their tendency to take risks using Zukerman's sensation seeking scale. (higher scores indicate a greater tendency to take risks.) The regression of sensation seeking scores on the three variable yields significant beta-weights of -0.30 with age; +.15 with sex (coded 1= female; 2= male) and -.20 with net income. the strongest effect is:

Sarah has devised a 30 iten scale with which she intends to measure the trait of extraversion. She measures the cronbach alpha ( square ) of her scale and finds it to be 0.40. what implications does this have?

Selecciona una de las siguientes respuestas posibles:

the scale is reasonable to use
the scales reliability is low but as for all scales the reliability could be improved by randomly cutting out half of the items
the critical question is whether Sarah's scale is capable of predicting such behaviour such as going to parties, appearing on stage etc.
The scale is quite badly flawed and Sarah should seriously look to redesigning or scrapping it.

One ( and only one) of the following statements is true of the Flynn effect. which one?

Selecciona una de las siguientes respuestas posibles:

There are no plausible explanations of how people could really have been getting more intelligent over the period 1930-1980
our current knowledge of the Flynn effect means that it is quite reasonable to use IQ tests to measure and compare, for example, the intelligence of people of different ages and backgrounds who may be competing for jobs
IQ as measured by intelligence tests continues to still be improving and at an ever increasing rate
there appear to have been greater increases in measured performance than verbal IQ over the period 1930-1980

an underestimate of the true real-life correlation
