Ch. 1: Thinking Critically With Psychological Science Outline The Need for Psychological Science
Two phenomena- hindsight bias and judgmental overconfidence- illustrate why we can’t rely solely on intuition and common sense. The Limits of Intuition and Common Sense Our intuition can lead us astray. Did We Know It All Along? Hindsight Bias Hindsight bias- The tendency to believe, after learning an outcome, that one would have foreseen it. (I-knew-it-all-along phenomenon) Common sense describes what has happened more easily than it predicts what will happen. Our intuition may tell us that familiarity breeds contempt, that dreams predict the future, and that emotional reaction coincide with menstrual phase.

When we notice random coincidences, we may forget that they are random and instead see them as correlated. We can easily deceive ourselves by seeing what is not there. Perceiving Order in Random Events Random sequences often don’t look random. Experimentation Exploring Cause and Effect Experiment- A research method in which an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (dependent variable). By random assignment of participants, the experimenter aims to control other relevant factors. * Manipulating the factors of interest & holding constant other factors. Manipulates a factor to determine its effect. Evaluating Therapies Double-blind Procedure- An experimental procedure in which both the research participants and he research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo. Commonly used in drug-evaluation studies. Placebo effect- Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance of condition, which is assumed to be an active agent. Experimental Condition- The condition of an experiment that exposes participants to the treatment, that is, to one version of the independent variable. Control Condition- The condition of an experiment that consists with the experimental condition and
Experimental is manipulation of one or more variables and control over variables. Clear definition shows that this study is not experimental because the variables are unable to be manipulated due to ethics. The current variables being studied are people who have suffered from CSA (childhood sexual abuse) or other childhood abuse and the likeliness that their distress well causes them to drink. It would be unethical to perform an experimental research on this research hypothesis. It would require choosing certain children to be subjected to childhood sexual abuse or any other abuse and a group that would not
Which term is used to describe the confusion of an event that happened to someone else with one that happened to you.
instead they have the deep memories of feelings. They can predict what will happen next by
7. Controlled experiment- An experiment that only tests one variable and the group being tested (experimental group) is compared to the control group (the group that isn’t testing the variable).
List three things you learned in each module. Module 1 a. The humanistic perspective, developed by psychologist Carl Rogers, focuses around the client and includes unconditional positivity for the patient. It strongly revolves around a person's emotional sense of self. b.
11. It is important to change one variable at a time in an experiment so you can identify the changes you made in the experiment.
Field experiments are those conducted in the real world and under normal social conditions, but following a similar procedure to the laboratory experiments. Participants in this experiment do not normally know that they are being studied in an experiment; this therefore eradicates the Hawthorne effect, but causes another undesirable outcome as it causes a problem with getting consent. Interpretivists are typically interested in using field experiments as they want to know how meanings and labels can get attached to different people and then how others then view them.
An answer may be found in the Dunning-Kruger effect: the curious phenomenon of “confident idiots” emboldened by their own ignorance, rather than cautioned by it.
Epstude, Roese, Spellman and Mandel as cited in Roesse and Morisson (2009) claimed that there was an assumption in current theorizing that counterfactual thoughts dramatize and underscore a causal inference that is already thought by the person to sensibly credible rather than creating the causal inference. In addition, counterfactual thoughts may influence blaming effects as well as overconfidence in past prediction. Likewise, counterfactual—induced causal inference may also influence future outcomes prediction. For instance, an individual might predict future triumphs featuring star player if a football victory was because of the said star player’s
The self-fulfilling prophecy is an important force in interpersonal communication, but it doesn’t explain or affect all behavior. There are certainly times when the expectation of an event’s outcome won’t bring it about.
Why is this phenomenon so important? Emily stark and Daniel Sachau discuss how those who cannot accurately access their abilities to avoid negative outcomes will stop protecting themselves from risks. For example, in Sachau and Stark’s literary review, they discuss previous studies that show this phenomenon. For instance, one study found that sexually active women see themselves as less likely to become accidentally pregnant, and thus are less likely to use contraceptives. In another study cited by Sachau; when people are overly optimistic about their abilities they show higher rates of accidental self-injury or demonstrate excessive risk-taking in business. Stark elaborates by discussing how people may underestimate their abilities or knowledge
In this experiment the substance that we are putting in the boiling water is the independent variable because we are measuring which substance will grow more crystals in meters .

As the current study is focused on exploring these biases across genders, it is essential to understand how male and females make their decisions. Significant similarities and differences have been noted on how males and females come up with their decisions (Wing, 2010). Generally, men are known to rush when it comes to decision making. Female characters, on the other hand, demonstrate thoughtfulness in decision making as they try to explore and communicate their concerns before making a logical conclusion. It can, therefore, be deduced that men are better decision makers than female characters in a situation that require immediate answers while females are good decision makers in case of critical matters that requires long-term thoughts. The hindsight and foresight bias is exhibited differently across genders. According to the study "The Hindsight Bias Effects in short-Term Investment Decision-Making," TChai (2012) found that both females and males demonstrate differences in their Hindsight bias and decision-making processes. According to the TChai (2012), hindsight bias remains higher in women than men in all types of events that were tested. In another study, that reported on the impact of hindsight and foresight bias on fear of the future illness found that there is a higher degree of hindsight bias in women than in men (Richard, Christopher, & Paul, 1993). As the study focused on the determination of fear level for cancer and noncancerous diseases among males and females, female characters in the study expressed more fear than men. The future fear can be attributed to hindsight bias, foresight bias as well as prior knowledge. This shows that women are more likely to engage in "I knew it all along" behavior as well as use their past experiences to predict the
Animal Experimentation is when scientists experiment on animals for medications and cures for humans. Scientists believe that experimenting on animals will help humans tremendously. However, these experiments are inhumane, throughout the procedures scientists are only worried about what they will learn not about how they are treating the animals.
