NEU 311L Exam Questions with Answers (100% Correct
Answers)
If we altered our in-class experiment such that 10 participants were
exposed to the almond oil condition for several minutes, and later that
day the same 10 participants were exposed to the lavender oil
condition, which test should be used to see if there is a significant
difference between the means of the control and experimental
conditions? Why? Answer: Paired samples (repeated measures) t test.
This is because a t test is used to compare two means. It is paired
samples because the 10 people in the study were each tested two
times, and so you have a pair of data points for each participant.
Feedback:
All of the participants were exposed to the both conditions, which
makes is a repeated measures design. It is a t test because there were
two conditions. An ANOVA would be used for more than two
conditions.
As described in the video, a Likert scale will be used during the class
experiment to have participants self-report how relaxed they feel. If a

participant filled out the Likert scale in the way shown in this image,
which score best approximates the score that should be given for this
response? Why? Answer: 27. The Likert scale we are using ranges from
0 (not relaxed) to 100 (extremely relaxed). Each small tick mark is 1 mm.
Each cm (indicated as a whole number on the ruler) is 10 mm. The blue
line is placed somewhere between the 2 cm and the 3 cm marker, so
the rating is somewhere between 20-30. The blue mark appears close
to the 7th tick mark past the 2, so a score of 27 is reasonable for this
data point.
Feedback: This is a 10 cm (100 mm) - long ruler. The score is
determined by the mm that the mark is closest to. Since the mark is
closest to the 2.7 cm (27 mm) mark, the score should be 27.
Which of the following statements is TRUE about
electroencephalography (EEG)? Answer: It picks up signals from
superficial layers of the brain, such as the cortex.
Feedback : Standard EEG signals originate in the cortex. The electrode
cannot detect signals from deeper structures nor from individual cells
since it is too far away from them! On the plus side, being able to pick
up cortical signals in a non-invasive manner makes EEG a great
