Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do. It is a way of deciding whether a claim is always true, sometimes true, partly true, or false.

Intuition & Common Sense
4
Many people believe that intuition and common sense are enough to
bring forth answers regarding human nature.
Intuition and common sense may aid queries, but they are
not free of error.
![Page 5: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/5.jpg)
Intuition – the ability to understand something immediately, without the need for conscious reasoning – know from feeling (gut feeling)
Common sense - sound and prudent judgment based on a simple perception of the situation or facts – knowledge and experience we already have/should have

Personal interviewers may rely too much on
their “gut feelings” when
meeting with job applicants.
We rely too much on our intuition.

Were there clues that led you to the “gut feeling”?
Did you get a bad evaluation? Did you hear someone talking about cuts in the workforce?
Is that intuition? or Are you consciously taking in all the information around you and applying it to the situation?

After learning the outcome of an event, many people believe they could have predicted that very
outcome. If we truly knew something bad was going to
happen before it did, why didn’t we do something to stop it? 11

1. How can we differentiate between uniformed opinions and examined conclusions?
2. The science of psychology helps make these examined conclusions, which leads to our understanding of how people feel, think, and act as they do!

The scientific attitude is composed of curiosity (passion for exploration), skepticism (doubting
and questioning) and humility (ability to accept responsibility
when wrong).
![Page 15: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/15.jpg)
Critical thinking does not accept arguments
and conclusions blindly.
It examines assumptions, discerns
hidden values, evaluates evidence and assesses conclusions.

Psychologists, like all scientists, use the scientific
method to construct theories that organize, summarize and
simplify observations.

![Page 17: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/17.jpg)
A Theory is an explanation that integrates principles and
organizes and predicts behavior or events.
For example, low self-esteem contributes to depression.

![Page 18: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/18.jpg)
A Hypothesis is a testable prediction, often prompted by a theory, to enable us to accept,
reject or revise the theory.
People with low self-esteem are apt to feel more depressed.

Research would require us to administer tests of self-esteem
and depression. Individuals who score low on a self-esteem test and high on a depression
test would confirm our hypothesis.

If each member of a population has an equal chance of inclusion into a
sample, it is called a random sample
(unbiased). If the survey sample is biased, its results
are not valid.27
Random Sampling
The fastest way to know about the marble color
ratio is to blindly transfer a few into a smaller jar
and count them.

Correlation Coefficient is a statistical measure of the relationship between two
variables.
30
When one trait or behavior accompanies another, we say the two
correlate.

Like other sciences, experimentation is the backbone of psychology research.
Experiments isolate causes and their effects.
37
Exploring Cause and Effect
![Page 38: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/38.jpg)
Many factors influence our behavior. Experiments (1) manipulate factors that interest us, while other factors
are kept under (2) control.
Effects generated by manipulated factors isolate cause and effect
relationships.
38
![Page 39: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/39.jpg)
An Independent Variable is a factor manipulated by the experimenter. The effect of the independent variable is the
focus of the study. For example, when examining the effects
of breast feeding upon intelligence, breast feeding is the independent variable.
39
![Page 40: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/40.jpg)
A Dependent Variable is a factor that may change in response to an independent variable. In psychology, it is usually a
behavior or a mental process.
For example, in our study on the effect of breast feeding upon intelligence,
intelligence is the dependent variable.

In evaluating drug therapies, patients and experimenter’s assistants should
remain unaware of which patients had the real treatment and which patients had the
placebo treatment.

Standard Deviation: A computed measure of how much scores vary around the mean.
Steps:1. Find the mean of the
distribution2. Subtract the mean from
every number in the distribution (ok to get a negative number)
3. Square the new numbers (multiply by self)
4. Add all the new square numbers together
5. Divide this new total by one less then the number in the distribution
6. Square root this new number

1. Representative samples are better than biased samples.
2. Less variable observations are more reliable than more variable ones.
3. More cases are better than fewer cases.

When is an Observed Difference Reliable?
![Page 58: 1. What is Critical Thinking? Critical thinking is a type of reasonable, reflective thinking that is aimed at deciding what to believe or what to do.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2d059/html5/thumbnails/58.jpg)
When sample averages are reliable and the difference between them is relatively large,
we say the difference has statistical significance.
For psychologists this difference is measured through alpha level set at 5 percent.

Q1. Can laboratory experiments illuminate everyday life?
Ans: Artificial laboratory conditions are created to study behavior in simplistic terms. The goal
is to find underlying principles that govern behavior.

Q3. Does behavior vary with gender?
Ans: Yes. Biology determines our sex, and culture further bends the genders.
However, in many ways woman and man are similarly human.

Q4. Why do psychologists study animals?
Ans: Studying animals gives us the understanding of many behaviors that may have common biology across animals and
humans.

Q5. Is it ethical to experiment on animals?
Ans: Yes. To gain insights to devastating and fatal diseases. All researchers who deal with animal research are required to follow
ethical guidelines in caring for these animals.

Q6. Is it ethical to experiment on people?
Ans: Yes. Experiments that do not involve any kind of physical or psychological harm beyond normal levels encountered in daily
life may be carried out.
