“…Another of these characteristics is age -most of our psychological research is being done with a very young group (age 18-24) when it is well known that such characteristics as intelligence (Wechsler, 1958;Norman and Daley, 1959;), social behaviour (Gollin, 1958;Schaie, 1959;Smith, 1960), and learning ability (Broadbent and Heron, 1962;Shephard and Abbey, 1962;Nyssen and Crahay, 1960;Wimer, I960), change substantially with ^ge. Such students are probably at the peak of their learning and intellectual abilities and this could mean that many findings in learning, especially verbal learning, could be special to the college student with limited applicability to other groups.…”

The purpose of this study was to examine the types of bias operating in the selection of •objects for psychological research with humans. A secondary purpose was to examine the effects of these biases on the generality and significance of findings in the most biased research areas. The Journal of Experimental Psychology and the Journal of Abnormal and Social Psychology for recent years were examined. It was found that 73% of the articles in the J-A.S.P. and 85.7% of the articles in the J.E.P. used college students, chiefly male students enrolled in introductory psychology. Use of the general adult population or even samples representing particular sectors of that population is very rare in J.A.S.P., and not found at all in the J.E.P. It was pointed out that the college population differs markedly from the adult non-college population in many characteristics which are associated with psychological factors, e.g. age, social class, learning ability. It is concluded that the male college student has become the "white rat" of human experimentation and that a broadening of the bases for selecting subjects for experiments is in order.

“…Gender plays a significant role in those respondents that complain of combined physical symptoms. Significant differences between men and women have been found in muscle performance and strength 27,28 . Logically, it can be assumed that a stronger person may be able to hold a transducer against the patient with less perceivable hand grip pressure than a weaker person.…”
