Provide two lines of evidence that we are especially sensitive to biological motion?



Answer:


  • Cutting and Koslowski (1978) 
  • given only point-light walkers to watch (a moving image with lights on representing major joints on the body), people have a high accuracy for detecting the sex and age of the walkers, but when the images are static and do not move, this accuracy drops significantly. Shoulder and hip differences make a big difference in determining the gender.
  • Pinto and Bertanthal (1994)
  • Infants at four months can differentiate biological versus non-biological movement (Pinto and Bertanthal, 1994)

In any organization, employees rely on the grapevine, particularly during times of uncertainty. The grapevine is an unstructured and informal network founded on social relationships rather than organizational charts or job descriptions. Although early research identified several unique features of the grapevine, some of these features may be changing as the Internet plays an increasing role in grapevine communication.

Examine the age-structure diagrams of Sweden and Kenya below, and answer the following questions.   Compare and contrast the two age structure diagrams in terms of two population dynamics - birth rate and death rate. Restatement: Given two age-structure diagram, Sweden and Kenya for 2000, compare and contrast the diagram in terms of population dynamics.  Age structure diagrams are basically divided into three major age categories: 1) Prereproduction (0-15 years old) 2) Reproductive (16-45 years old) 3) Postreproduction (46 years old-death) Birth Rate Sweden  1) Population has nearly equal proportions of pre-reproductive and reproductive individuals. 2) Little growth over a long period of time will produce a population with about equal numbers of people in all age groups. 3) Children not required or necessary to support parents.  4) Availability and acceptance of birth control. Kenya 1) Population had pyramid-shaped age structu...
