Group 6 Experiments

Who was the earliest person who could have reasonably claimed the title of the First Experimental Psychologist?

• Ernst Weber

• Selig Hecht

• Les Guice

• Gustav Fechner

Which branch of psychology was Weber the founder of?

• clinical psychology

• behaviorism

• forensic psychology

• psychophysics

Who injured his eyes from staring at the sun through colored lenses for long periods of time?

• Eleanor Gibson

• Sigmund Freud

• Gustav Fechner

• Richard Walk

What was the logarithmic relation Fetcher came up with from Weber's law to try to explain physical and psychological differences using sound?

• a^2+b^2=c^2

• S= K log I

• e= mc^2

• dPdt=rP(1-PK)

Answer explanation

S is subjective magnitude measured in jnds, I is physical intensity measured in physical units, and K depends on several things (which channel and which units we use for our physical measurement)

What experiment did Selig Hecht perform?

• Little Albert

• Stanford Prison Experiment

• Adaptation to the Dark

• A Class Divided

What was found in the experiment done by Hecht and Mandelbaum in 1938?

• Vitamin A deficiency leads to night blindness

• Intelligence can be measured by connections

• Law of Effect

Answer explanation

People with a Vitamin A deficiency could suffer from night blindness, which means they cannot see in the dark while they can see everything in broad daylight. 

Who was the focus in Bruner's first experiment with Goodman in 1947?

• Elderly

• People in higher administration

• Highschoolers

• 10 year old schoolchildren

What was found from the experiment with the 10 year old schoolchildren?

• They are able to perceive depth

• It was found that the higher the value of the coin, the bigger they made the size

• Reviewing each day is better than cramming

• How quick they were able to judge their classmates based off their eye color

Answer explanation

Children from affluent and non affluent areas were asked to hold a coin and move the knob to make the light on the wall match the size of the coin. It was found that the higher the value of the coin, the bigger the children made the size. An example would be the dime. The dime is smaller than the penny but because it is worth more, the children made it bigger

How did the visual-cliff experiment occur to Eleanor Gibson?

• While eating a picnic lunch at the Grand Canyon

• In her home

• While on a walk in the park

• In a dream

Answer explanation

While she was eating a picnic lunch at the Grand Canyon, she asked herself if a toddler would see the edge of the canyon as a dangerous place. If they did then they must be able to perceive depth. 

How did Eleanor Gibson and Richard Walk perform their experiment with the toddlers?

• They made a visual cliff made out of two checkerboard patterns

• They took the toddlers to the Grand Canyon

• The experiment was never completed

Answer explanation

In their first experiment, they took human babies between the ages of 6 and 14 months old. They chose this age group because it meant they had a little visual experience but not like an adult and it was likely they never came close to falling off a cliff before. They made a visual cliff made out of two checkerboard patterns and they were arranged so that one was mounted 40 inches above the other. However, it was completely safe; they had a non-reflective transparent sheet of plastic that guarded the edge of the upper checkerboard. They strictly wanted to see if the baby would carelessly crawl around to the edge or if they would stay back and away from the edge.
