| Description | Report titled 'Some Effects of Mental Stress on Matrix Test Scores.' (no. 164) by Philip E. Vernon.
Two copies of the same report. The report was motivated by an observation that indviduals who were asked to complete a matrix test without prior notice and in small groups, or individually, have consistently scored poorer marks than they may have done under different circumstances. The report analyses these scores against test results of volunteers who have completed the test during a scheduled appointment. Results showcase a difference of 2-3 marks between individuals who completed a scheduled test, compared to those with no appointment, with the latter group performing worse overall. The text concludes that this may be an indication of the effect of mental stress on performance on mental ability tests. |
