Basic Feature of Experimental Psychology

1. Basic Feature of Experimental Psychology

2. Experimental Method • The experimental method consists of variable manipulation to set up the cause and effect relationship. The major feature have been regulated by methods along with allocation of the participants into experimental and controlled groups.

3. Experimental Psychology • Experimental psychology indicates a work accomplished by those individuals who apply the experimental methods. They are involved in the psychological research. There are processes which are associated with it. The experimental psychologists associate with the human participants and there are animals who are involved with different topics, e.g., sensation and perception, cognition, memory, motivation, learning, emotion. There are social psychology, developmental processes, along with the neural substrates.

4. Empiricism • There is a fundamental assumption in science. They are factual statements across the world which is associated with the global observations. It involves testing of theories and hypotheses against the observations of our natural world in comparison to the intuition, priori reasoning, or revelation.

5. Testability • It has been associated with empiricism. It represents a concept which is quite beneficial. It is a law based on science. There is testability in the theory. There are methods of research. When the theory could not be tested in conceivable way, subsequently, scientists regard that theory lacking meaning. The testability indicates falsifiability. It is a concept where there are observations and it is going to tell the theory as wrong.

6. Determinism • Experimental psychologists are going to take the idea of determinism. It is an assumption where the situation of object could be understood by prior states. The behavioral phenomena have been shared on the basis of the cause and effect. When the phenomenon has been general, it has been known as law.

7. Parsimony • The parsimony represents the search for the simplicity. For instance, the scientists have made an agreement that when two theories deal with the group of the empirical observations equally well. We must choose a parsimonious of two. The parsimony had been shared by a middle aged philosopher William of Occam.

8. Experiment on Human Participants • There are experiments where the human participants could reply to respond to the visual or auditory stimuli. They obey the instructions offered by that experimenter. There is an instruction from animals by sharing the right responses. From 1990s, there is utilization of computers for automating the presentation of stimulus. There is a behavioral measurement in a particular laboratory. The behavioral experiments have been conducted on animals and human beings. They observe the reaction time along with the choices associated with two alternatives.

9. Crucial Experiment • The crucial experiment represents the experiment which is going to test a number of hypotheses. We need confirmation of the hypothesis and there is rejection from others. The data had been regular on hypotheses. The result asks for research to reduce the possibilities.

10. Pilot Study • The pilot study are involved in major experiment. The goal is to check new procedures and understand the optimal value in experimental variables. They are going to discover weakness in the experimental design.

11. Field Experiment • The participants have observed naturalistic setting other than the laboratory. There are field experiments which is new from field studies for the environment. It has been modified in the perfect way.

12. Ordinal measurement • The ordinal scale begins with ranking or ordering objects. There are experiments in psychological experiments. It had got numbers of that type. For instance, the participant will rank odors like A has been quite pleasant rather than B. B had been quite pleasant rather than C. The rankings are not going to inform us about the level of odor, which is different from one another.

13. Interval Measurement • An interval scale involves the equality in differences between things calculated. It presents numbers form over the interval scale when there are differences between numbers associated with the differences between properties calculated. For example, an individual can tell difference between 5 and 10 degrees using the thermometer of Fahrenheit is same as difference between 25 and 30. We cannot tell that using something with the temperature measuring 20 degrees Fahrenheit.
