The Focus on Neuroscience: Vision, Experience, and the Brain box describes the visual experience of Mike May, who regained partial sight in one eye after 40 years of blindness. The text described the fact that Mike was able to quickly identify moving objects, but had trouble identifying complex objects that were stationery, including faces. As your text explains, neuroscientists who worked with Mike believe that Mike's experience reflects the fact that:

(A) motion perception pathways develop later than face and object recognition.
(B) motion perception pathways develop earlier than face and object recognition.
(C) the ability to perceive moving objects requires more cognitive effort than the ability to perceive complex but stationary objects.
(D) Mike was able to combine visual signals from both eyes to identify moving objects

Asociologist wants to study a culture that occurs in some women’s prisons: “state families,” in which individual prisoners take on certain roles within a group of like-minded prisoners. there is previous evidence that younger prisoners will use older inmates who play the roles of grandparents as a resource before they will turn to staff for and advice. the lieutenant in charge of a dorm of long-term prisoners offers to gather volunteers to speak to the researcher and also offers to vouch for the integrity of the researcher. the use of this staff is: a valid use of a statistical technique referred to “snowball sampling” wherein the inclusion of the first subject leads to the recruitment of another one subject.a useful tactic in obtaining a sample of prisoners who both meet the criteria and who will be honest with the researcher.wrong and is prohibited; subject selection needs to be free from intervention by prison authorities or prisoners.acceptable only when the researcher’s irb grants a special waiver.
