STA 210 Chapter 1 HW Flashcards

Cocaine Use Statistics

• Cocaine use among children increased from 1.4% in 2004 to 1.9% in 2005, a rise often reported as "doubles" from 1% to 2%.
• The figures indicate that while the increase might seem significant, it reflects rounding in reporting the statistics.

Visual Field Experiment with Joe

• When presented with an item in his left visual field, Joe reported he saw nothing, indicating possible visual processing issues.
• Joe accurately identified the item shown in his right visual field, reporting he saw a hammer when it was presented.

Left and Right Hemisphere Functionality

• Joe's ability to draw the saw with his left hand, when it appeared in his left visual field, suggests intact motor skills linked to the right hemisphere of the brain.
• This highlights the differences in visual perception and motor response based on which side of the visual field the object is presented.
