How the human brain detects
the ‘music’ of speech
1.
In one
sentence, what was the research about?
a.The lab
was trying to figure out how the brain hears sounds and turns it into a
meaning.
2.
How many
subjects were used in the experiment?
a.
10
volunteers
3.
Was there
a control group?
a.
No
4.
How were
the subjects chosen?
a.
Chang, a
neurosurgeon, specializes in surgeries to remove brain tissue which causes
seizures in people with epilepsy. To get ready for surgery, he would place
high-density arrays of electrodes onto the patient’s brain to help locate where
the seizures are triggered from. So Tang, a student from the Chang lab, chose
10 people who were awaiting the surgery.
5.
What did
the experimenters do to the subjects?
a.
They had
them listen to 4 different recorded sentences that were spoken by different
synthesized voices which could change the meaning of the sentences.
6.
How did
the subjects react?
a.
They
found out that some neurons could tell the difference between the different
speakers, and other neurons could tell the difference between the 4 sentences
no matter which speakers was talking.
7.
Did the
subjects act the way the experimenters expected?
a.
Yes
1.
In one sentence, what was the research about?
a.
Researching the fact that our self-worth develops
fairly early in life and that failure can introduce discouragement a lot sooner
than thought.
2.
How many subjects were used in the experiment?
a.
It didn’t specifically say, but it was a series of
children from ages four to seven.
3.
Was there a control group?
a.
No
4.
How were the subjects chosen?
a.
They were just chosen randomly
5.
What did the experimenters do to the subjects?
a.
They asked them to imagine that they couldn’t do
something, whether they told them it was easy or very difficult. They were then
asked about their abilities and about their self- worth.
6.
How did the subjects react?
a.
They showed that children as young as four years old
have a reason of self-worth and global sense. When they were told they failed
an easy task, it lowered their thought of their abilities but not their
self-esteem. However; when they were told they failed a hard task, it lowered
their self-esteem, not their thought of their abilities.
7.
Did the subjects act the way the experimenters
expected?
a.
It didn’t say how they thought the experiment would go.
How the emotions of others influence our olfactory sense
1. In one sentence, what was the research about?
a.
The facial expressions of
other people and how we perceive an odor.
2. How many subjects were used in the experiment?
a.
It didn’t specifically say,
just that they had participants.
3. Was there a control group?
a.
No, all of the participants
were just normal people, with nothing different that they did to any of them.
4. How were the subjects chosen?
a.
randomly
5. What did the experimenters do to the subjects?
a.
They had them look at a
picture of a person with happy, neutral, or disgusted facial expressions and
then had them rate different scents after they saw the picture.
6. How did the subjects react?
a.
When they saw a happy face,
they rated the smell higher; when they saw a disgusted face, they rated the
smell poorer.
7. Did the subjects act the way the experimenters expected?
a.
Yes. And in past studies,
they would show the picture and give the scent at the same time and it showed
similar results. But with the recent study, it proved that our senses are
activated before we even smell the scent.
1. In one sentence, what was the research about?
a. How removing a certain gene encoding can affect the levels of stress and
anxiety.
2. How many subjects were used in the experiment?
a. Over 20
3. Was there a control group?
a. No
4. How were the subjects chosen?
a. randomly
5. What did the experimenters do to the subjects?
a. They tallied the genes that were most disrupted by the loss of the gene
Lef1 encoding.
6. How did the subjects react?
a. Over 20 fish were had mood disorders such as depression and anxiety.
They grew slowly in a new tank which was a condition related to stress
7. Did the subjects act the way the experimenters expected?
a. They didn’t say, but I’m assuming they did otherwise they wouldn’t have
thought of this theory to experiment with.
