PART I
Overview
PART ~ CONSISTS OF THREE CHAFERS. Chapter 1 sets the stage for the
report. It describes the committee's task, provides background on
the Army's interest in enhancement techniques, characterizes specific
techniques examined by the committee, and identifies the main issues in
evaluating the relation between techniques and human performance.
Chapter 2 presents the committee's findings and conclusions. We draw
general conclusions about the process of consideration given to any
technique and state specific findings and conclusions for each of the areas
of human performance examined.
Chapter 3 presents the committee's philosophy of evaluation as it
pertains to enhancement techniques. Some of the issues involved concern
the conduct of basic research; others concern the conduct of field tests.
With respect to basic research, issues include the plausibility of inferences
about novel concepts, causation, alternative explanations of causal
relations, and the generalizability of causal relations. With respect to
field tests, a number of questions are of interest: Does the enhancement
program meet genuine Army needs? Is the resulting program implement-
able, given program design and resources? Do unintended side effects
limit utility? Is the program more cost-effective than its alternatives?
These questions underscore the reality that evaluation research is largely
a pragmatic activity influenced by the organizational context in which it
occurs.
