Dr. Winstell is interested in studying prejudice, and devises a study in which Caucasian participants are led to believe that they are chatting electronically with an African-American participant. In reality, the participants are responding to another Caucasian participant, and she discloses this information to all participants at the end of the study. Dr. Winstell has used in her study.

Dr. Winstell has used parody participant in her study.

Explanation:

Dr. Winstell is very much aware that, for her study to be successful, she needs to be able to create the impression that what the participants was told is what is actually being done.

This is the reason why he adopted the parody (fake) participants inorder to create the impression that, the participants in the experiment are actually chatting with the African-American as they were initally told.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
