Some more sensitive measures of sensitivity and response bias.

Abstract

Keeping you up-to-date. All APA Fellows, Members, Associates, and Student Affiliates receive-as part of their annual dues-subscriptions to the American Psychologist and APA Monitor. High School Teacher and International Affiliates receive subscriptions to the APA Monitor, and they may subscribe to the American Psychologist at a significantly reduced rate. In addition, all Members and Student Affiliates are eligible for savings of up to 60% (plus a journal credit) on all other APA journals, as well as significant discounts on subscriptions from cooperating societies and publishers (e.g., the American Association for Counseling and Development, Academic Press, and Human Sciences Press).Essential resources. APA members and affiliates receive special rates for purchases of APA books, including the Publication Manual of the American Psychological Association, and on dozens of new topical books each year.Other benefits Of membership. Membership in APA also provides eligibility for competitive insurance plans, continuing education programs, reduced APA convention fees, and specialty divisions.

Is signal detection theory fundamentally flawed? A response to Balakrishnan (1998a, 1998b, 1999)

“…Equation 3 suggests that if we could estimate the area between the two probability distribution functions underlying a discrimination experiment, this would estimate Balakrishnan (1998b) appears to be doing with his new sensitivity index, S9, which he puts forward as "an estimate of the difference between the means of two distributions" ( p. 69). Balakrishnan (1998b) derives S9 for the rating procedure only.…”

“…Balakrishnan (1998b) derives S9 for the rating procedure only. The derivation, slightly simplified, is illustrated in Figure 3.…”

“…The account it provides of the processing of sensory information and the operation of the sensory decision-making process is now built into the fabric of much of experimental psychology. In three recent papers, Balakrishnan (1998aBalakrishnan ( , 1998bBalakrishnan ( , 1999 has claimed, however, that an alternative index is "better justified" than d9 and that SDT is fundamentally flawed and must be rejected. His argument is based on the use of new measures that he has developed and applied experimentally.…”

Type I error rates and power analyses for single-point sensitivity measures

“…The bias and precision of d and A have been studied fairly thoroughly (Hautus, 1995;Kadlec, 1999;Miller, 1996;Verde, Macmillan, & Rotello, 2006). Their robustness to violations of their equal-variance assumptions has also been explored (Balakrishnan, 1998;Donaldson, 1993;Verde et al, 2006). In this article, we ask two different statistical questions about each of these single-point sen-rejected.…”
