The Wechsler Intelligence Scale for Children Essay

The Wechsler Intelligence Scale for Children - Essay Example The WISC-III was standardized on a representative sample in North America based on U.S.A. census data for 1988 (N = 2,200) (Canivez, Neitzel, & Martin, 2005). The sample was stratified across age, gender, ethnicity, geographical region, parental occupation, and urban-rural residency (Kaplan & Saccuzzo, 2001). A four-factor model of index score is widely supported (i.e., Verbal Comprehension, Perceptual Organization, Freedom from Distractibility, and Processing Speed) (Canivez, Neitzel, & Martin, 2005). The WISC-III has high internal consistency for all three IQ scores and the four factors, ranging from .80 to .97 (Canivez, Neitzel, & Martin, 2005; Kaplan & Saccuzzo, 2001). This reflects the 11 subtests (Symbol Search and Coding excluded) reported moderate to excellent internal consistencies, of .61 to .92 (Kaplan & Saccuzzo, 2001). Split-half reliabilities for the three IQs in 1991 were found to be .96 (FSIQ), .95 (VIQ), and .91 (PIQ) (Kaplan & Saccuzzo, 2001). Standard errors of measurement for FISQ, VIQ and PIQ average at 3.20, 3.53, and 4.54 respectively (Kaplan & Saccuzzo, 2001).

The findings reported weapon points which had knives and scrappers as well as fire places. Some of their characteristics include the art of hunting in groups by the use of weapons such as spears during hunting. These ancient spear heads and weapons were made from carved stone. The hunters used large blocks of stone or flint tomake cores, whereby they selected large pieces of blades to make their spear tips. This art of chipping stone was common amongst the Clovis and Folsom hunters. The tips made by each group are named according to the group which made them, such as Clovis points. As found in most ancient groups, the males did the hunting tasks while the women fended their young ones. The women also did other tasks such as gathering and collecting food and sometimes the minor wild animals.3 They also assisted in preparation of hide and skin for other uses as well as prepare and cook food for their families.
