effect. It is done in a controlled environment so that extraneous variables are prevented from affecting the results. Behaviourists use lab experiments because they are interested in a cause and effect of certain behaviours. The aim is to control all relevant variables except for one key variable‚ which is altered to see what the effect is. The variable that you alter is called the independent variable. An independent variable is a variable directly manipulated by the researcher. The laboratory

associate stimuli c. Method: laboratory experiment d. Procedure: They paired various neutral stimuli‚ such as a tone‚ with food in the mouth to see if the dog would begin salivating to the neutral stimuli alone. To eliminate the possible influence of extraneous stimuli‚ they isolated the dog in a small room‚ secured it in a harness‚ and attached a device that diverted its saliva to a measuring instrument. From an adjacent room they could present food‚ at first by sliding in a food bowl‚ later by blowing

Where as Descriptive studies do not seek to measure the effect of a variable; they seek only to describe and causal relationships investigate the effect of one or more variables on one or more outcome variables. This type of research also determines if one variable causes another variable to occur or change

He divides 100 subjects into two groups of 50‚ and experimental group and a control group. He dissolves drug A in saline solution and injects it into all the subjects in the experimental group. He then gives all the control group subjects an injection of only saline solution. The independent variable in this case is

ATTENTION: -Lab Stroop Effect’s Theory: During the experiment‚ it was more difficult to indicate the color ink that the word was shown in when the word itself indicated a non-corresponding color. This is the Stroop Effect: the finding that people identify the color of a word more slowly when color and word are incongruent (for example‚ the word BLUE printed in a red color) than when color and word are congruent (for example the word BLUE printed in blue). But why is identifying the color of
