Change the subject, apparatus, or procedure in order to obtain a slightly different  perspective. In this case, you maintain the same process thought to be the causal  factor, but you freely change whatever is thought to be “irrelevant” factors  (systematic replication).  Many pioneering research studies did not use what have become the best  measures for the independent and dependent variable. Measure the  behavior directly rather than indirectly. Measure it more accurately, or  move up from a nominal, ordinal, or interval, to a ratio scale.  Example: You refine the "interest" measure into those which simply show  interest, those which ask for a fact, and those which ask for some  integration of information. You then compare the effectiveness of each.

Unformatted text preview: Occasionally research is published with an unobserved confound which you may notice. The study can be redone without the confound. Example: You read an article which manipulated a variable intended to increase exploration in rats (it failed). You realize that it was conducted during the day when rats normally sleep. You redo the experiment and run it during the dark part of the rat's light cycle. General functional relationships may or may not apply to specific situations. Measure what is proposed to be a general effect in a particular group. Example: The effectiveness of social attention on studying behavior was examined in students from lower socioeconomic status families....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
