Psyo 315 midterm 1 Exam Questions
With Correct Answers
Transduction - CORRECT ANSWER✔✔-process of transforming energy in
| | | | | | |
the environment into electrical energy in the neurons
| | | | | | | |
threshold - CORRECT ANSWER✔✔-minimum amount of energy required
| | | | | | |
for a person to say that they feel something
| | | | | | | | |
what is the first crossover point for the method of limits example given -
| | | | | | | | | | | | |
CORRECT ANSWER✔✔-98.5 is the first crossover point
| | | | | | |
Gustav Fechner (What are the 6 things he proposed) - CORRECT
| | | | | | | | | | |
ANSWER✔✔-- Provided a new way to study the mind | | | | | | | | |
- The mind and body thought to be separate from each other
| | | | | | | | | | | |
- people saw body was physical and therefore something that could be
| | | | | | | | | | | |
seen, measured, studied but the mind was not physical
| | | | | | | | |
- Fechner thought mind and body should not be thought of separately
| | | | | | | | | | | |
but as two sides of single reality
| | | | | | |
- Fechner proposed that the mind could be studied by measuring the
| | | | | | | | | | | |
relationship between changes in physical stimulation (body) and
| | | | | | | |
persons experience (mind) | |
,absolute threshold - CORRECT ANSWER✔✔-smallest stimulus level that
| | | | | | | |
can just be detected
| | |
Method of limit - CORRECT ANSWER✔✔-: In the method of limits the
| | | | | | | | | | | |
experimenter presents stimuli in either ascending or descending order
| | | | | | | | |
- When using the method of limits, the threshold is determined by
| | | | | | | | | | | |
calculating the average of the crossover points
| | | | | |
difference threshold - CORRECT ANSWER✔✔-smallest difference
| | | | | |
between two stimuli that allows us to detect the difference between
| | | | | | | | | | |
them
explain how the method of limits would work if used as a test for
| | | | | | | | | | | | | |
hearing - CORRECT ANSWER✔✔-- discussing person's threshold for
| | | | | | | |
hearing experimenter presents a tone with intensity 103 and then
| | | | | | | | | |
observer indicated a yes response that he hears the tone this is not the
| | | | | | | | | | | | | |
threshold
- then presents another tone at lower intensity and observer responds
| | | | | | | | | | |
to that tone procedure continues until observer responds no
| | | | | | | |
what is the method of adjustment - CORRECT ANSWER✔✔-the subject
| | | | | | | | | |
adjusts the intensity continuously until they can just barely detect the
| | | | | | | | | | |
stimulus
, what is the advantage of the method of adjustment? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-it is faster becuase faster because subjects can determine
| | | | | | | | |
their threshold in a few trials by adjusting intensity themselves
| | | | | | | | |
crossover points* - CORRECT ANSWER✔✔-vary differently so procedure
| | | | | | |
is done many times below and above
| | | | | | | |
- The threshold is then determined by calculating the average of all
| | | | | | | | | | | |
crossover points |
what is the advantage of the method of constant stimuli? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-It is the most accurate method because it involves many
| | | | | | | | | |
stimuli and the stimuli are presented in random order. This minimizes
| | | | | | | | | | |
how the presentation of a previous stimulus can effect how the person
| | | | | | | | | | | |
responds to the next one. | | | |
what is the disadvantage of the method of constant stimuli? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-it is very time consuming | | | |
Difference threshold - CORRECT ANSWER✔✔-minimum difference that
| | | | | | |
must exist between two stimuli before we can tell the difference
| | | | | | | | | | |
between them |
