Questions and Answers

As psychologist, we take a scientific approach to understanding behavior, and our knowledge about psychological processes is based on _______accumulated through research.

Scientific evidence

It is a content and a process

Science

It is a scientific technique used to collect and evaluate data

Methodologies

It is a facts we gather using scientific method

<p>Data</p> Signup and view all the answers

It is a nonscientific data gathering that shapes our expectations and beliefs and directs our behavior toward others.

<p>Commonsense psychology</p> Signup and view all the answers

It is a belief about behavior are derived from data we collect from our own experience and what we have learned from others.

<p>Commonsense psychology</p> Signup and view all the answers

It is a belief about behavior can be unreliable, and the explanations and predictions that we derive from them are likely to be imperfect.

<p>Commonsense psychology</p> Signup and view all the answers

Its the use of information to explain or predict behavior

<p>Nonscientific</p> Signup and view all the answers

People misuses data to estimate the probability of an event, like when a slot machine will pay off.

<p>Gambler's fallacy</p> Signup and view all the answers

This is the mistaken belief that past random events affect the likelihood of future independent events.

<p>Gambler's fallacy</p> Signup and view all the answers

Falsely assume that specific behaviors cluster together due to shared group membership.

<p>Stereotyping</p> Signup and view all the answers

This is the tendency to assign generalized traits to individuals based on their membership in a particular group.

<p>Stereotyping</p> Signup and view all the answers

It is the tendency to seek out, interpret, and remember information that supports pre-existing beliefs while ignoring contradictory evidence.

<p>Confirmatory bias</p> Signup and view all the answers

Feel more confident about our conclusions than is warranted by available data. It can result in erroneous conclusions when we dont recognize the limitations of supporting data.

<p>Overconfidence bias</p> Signup and view all the answers

It is often make unwanted dispositional attributes and underuse situational information. It can reduce the accuracy of our explanations and predictions.

<p>Overusing trait explanations</p> Signup and view all the answers

This bias involved overemphasizing personality traits as explanation for behavior while underestimating situational factors.

<p>Overusing trait explanations</p> Signup and view all the answers

This occurs when individuals overestimate their knowledge, ability, or accuracy in judgments.

<p>Overconfidence bias</p> Signup and view all the answers

This assumes that behavior follows a natural order (patterns and principles) and can be predicted.

<p>Scientific mentality by alfred north whitehead</p> Signup and view all the answers

This assumption is essential to science. There is no point to using the scientific method to gather and analyze data if there is no implied order or connection.

<p>Scientific mentality by alfred north whitehead</p> Signup and view all the answers

If order ( patterns and principles) exists, then it can be described in a systematic way by collecting data that are observable or experienced

<p>Empirical data</p> Signup and view all the answers

It consists of statements generally expressed as equations with few variables that have overwhelming empirical support.

<p>Law</p> Signup and view all the answers

These laws are useful in the physical science

<p>Law of gravity and thermodynamics</p> Signup and view all the answers

It is an interim explanation; a set of related statements used to explain and predict phenomena.

<p>Theory</p> Signup and view all the answers

This is an integrate diverse data, explain behavior, and predict new instances of behavior.

<p>Theory</p> Signup and view all the answers

It is critical to the scientific method. We engage to this when data collection and interpretation are systematic, objective, and rational.

<p>Good thinking</p> Signup and view all the answers

An aspect of good thinking, stating that a simplest explanation is preferred until ruled out by conflicting evidence; also known as occams razor

<p>Parsimony</p> Signup and view all the answers

Modern scientist accept their uncertainty of their own conclusions. Changes in scientific explanations and theories are an extremely important part of scientific progress.

<p>Self-correction</p> Signup and view all the answers

It is an exact or systematic repetition of a study.

<p>Replication</p> Signup and view all the answers

It increases our confidence in experimental results by adding to the weight of supporting evidence.

It is the capability if knowing in advance when certain behaviors should occur.

It is the systematic noting and recording of events

<p>Observation</p> Signup and view all the answers

It means that the procedures are consistently applied

<p>Systematic</p> Signup and view all the answers

The events or their signs must be observable. Observations must be objective so that there can be strong agreement among raters.

It is the process we use to test the predictions we call hypotheses and establish cause-and-effect relationship. This is not always possible because our predictions must be testable.

<p>Experimentation</p> Signup and view all the answers

We must be able to manipulate the independent variable and measure its effect on the dependent variable. Ethical concerns or technological limitations may prevent this.

<p>Experimentation</p> Signup and view all the answers

An experiment required that we create at least _________ and randomly assign subjects to these conditions. In psychology experiments, we control extraneous variable so that we can measure "what we intend to measure"
