Suppose Dr. Alimam covered the shape with a towel as the infant was exhibiting interest. Explain what would most likely be a key difference in the way the three-month-old infants would react toward this versus the way the eight-month-old infants would react. BoldItalicUnderline

Cerebellum
Area in the back at the bottom of the brain help maintain balance where she must have gotten hit
At a schoolwide pep rally preceding a big game at Williams James High School, each grade has a designated t-shirt color and seating area in the bleachers. Student leaders organize classes so that their colored shirts combine to form the school flag. The coach gives an exciting speech, the cheerleaders perform a routine, and the band plays the school song while the students sing in unison. Cocktail party effect

ashley is scared of guarrails
Ashley planned to drive from New York to California to attend college. However, shortly after departing, she became uncertain about which roads to take and called her parents for assistance with directions. Because she was distracted, she drove off the side of the road and grazed the front bumper of her car on the guardrail. Fortunately, the car was not too badly damaged, so she continued on her journey. Although she ultimately made it to California, she had a lingering fear of guardrails for several months following her experience. motor neurons
ashleys motor neurons would allow her to press the gas pedal on her car
Statistics are often used to describe and interpret the results of intelligence testing. Describe three measures of central tendency (mean, median, and mode). Describe a skewed distribution. Relate the three measures of central tendency to a normal distribution. Relate the three measures of central tendency to a positively skewed distribution. An intelligence test for which the scores are normally distributed has a mean of 100 and a standard deviation of 15. Use this information to describe how the scores are distributed. In two normal distributions, the means are 100 for group I and 115 for group II. Can an individual in group I have a higher score than the mean score for group II? Explain.
average, middle, most occuring asymmetrical distribution of scores mean median and mode are close mean largest 85 - 115 68% Yes, mean average

For each method listed above, explain a key characteristic of the basic approach you could use to reach a scientific conclusion about the relationship between taking vitamin J and improving memory. You need not design a complete study.
case - study 1 person corr - discuss correlation exper - manipulation of J variable
Discuss one advantage of each research method listed above. Case study Correlational study, and Experiment.
case study - can study unusual cases correlation - efficient, save time and money while getting lots of data experimentreplication
Apply knowledge of psychological research in answering the following questions about intelligence scores. Explain why norms for standardized intelligence tests are periodically updated. Describe how to determine whether an intelligence test is biased.
change in knowledge = smarter (flynn effect)= new tests test does not accuratly predict teh future performance of a group
Dr. Franklin investigated the relationship between stress and physical illness. She persuaded a high school principal to require all female athletes in the school to participate in her study. She explained the purpose of her research to the athletes and asked them to use a standard form to rate the severity of their stress over the last six months. More than 250 athletes completed the form. Then Dr. Franklin analyzed the forms returned by the first 100 athletes. She requested the attendance records from the nurse's office for each of those athletes to verify the number of days absent due to illness during the same six-month period. In the debriefing summary that Dr. Franklin sent to the 100 athletes after she completed the study, she stated that athletes who reported more stress also experienced more frequent illness. Dr. Franklin concluded that stress causes physical illness. Identify the research method used by Dr. Franklin.

Identify ONE statistical technique that Dr. Franklin could use to represent the relationship between the variables in the study.

Dr. Alimam is studying infants' ability to distinguish shapes. He shows an infant a shape until the infant loses interest in the shape, and then he shows the infant a different shape. If the infant shows interest in the new shape, he determines that the infant recognizes that the new shape is different from the old one. Dr. Alimam expects that getting older will cause the babies to recognize shapes faster. He records how long it takes the infant to show interest in the new shape. Describe how the data illustrate the habituation process. Identify the mode for three-month-old infants. Describe the correlation between time and an infant's age. Identify the dependent variable. Describe how Dr. Alimam could use replication to conduct a better-designed study. Explain how the data support or do not support the hypothesis.
decreased responsiveness with increased stimulation over time they got used to the study and understood the differences with new chapes 15 seconds time dec as ahe inc time he could use the same babies over time supports it

A researcher designs a study to investigate the effect of feedback on perception of incomplete visual figures. Each participant stares at the center of a screen while the researcher briefly projects incomplete geometric figures one at a time at random positions on the screen. The participant's task is to identify each incomplete figure. One group of participants receives feedback on the accuracy of their responses. A second group does not. The researcher compares the mean number of figures correctly identified by the two groups. Identify the independent and dependent variables in the study.
no feedback number of figures identified
