The statement that is being tested against the null hypothesis is the alternative hypothesis. [2] Alternative hypothesis is often denoted as H a or H 1. In statistical hypothesis testing, to prove the alternative hypothesis is true, it should be shown that the data is contradictory to the null hypothesis. Namely, there is sufficient evidence ...
Heuer outlines the ACH process in considerable depth in his book, Psychology of Intelligence Analysis. [1] It consists of the following steps: Hypothesis – The first step of the process is to identify all potential hypotheses, preferably using a group of analysts with different perspectives to brainstorm the possibilities. The process ...
Social psychology utilizes a wide range of specific theories for various kinds of social and cognitive phenomena. Here is a sampling of some of the more influential theories that can be found in this branch of psychology. Attribution theory – is concerned with the ways in which people explain (or attribute) the behaviour of others. The theory ...
The theory of rational counterfactuals identifies the antecedent that gives the desired consequent necessary for rational decision making. For example, suppose there is an explosion in a chemical plant. The rational counterfactual will be what should have been the situation to ensure that the possibility of an explosion is minimized. [46] [47]
In this situation, if the estimated value exists in one of the one-sided critical areas, depending on the direction of interest (greater than or less than), the alternative hypothesis is accepted over the null hypothesis. Alternative names are one-sided and two-sided tests; the terminology "tail" is used because the extreme portions of ...
This strategy is an example of a heuristic: a reasoning shortcut that is imperfect but easy to compute. [63] Klayman and Ha used Bayesian probability and information theory as their standard of hypothesis-testing, rather than the falsificationism used by Wason. According to these ideas, each answer to a question yields a different amount of ...

In contrast to earlier association-type theories, the Hypothesis Theory argues that subjects solve this problem (i.e., learn the correct response to each stimulus), by testing a series of hypotheses about the relation of the cue values (stimulus features) to the class. For example, a candidate hypothesis for stimuli that vary along the three ...
