abstract="Signal detection analysis was used to examine the effects of d-amphetamine and of morphine on auditory discrimination in female rats. The probability of response repetition in the discrete trial two-choice discrimination procedure was used as an additional behavioral measure. d-Amphetamine (0.4-3.2 mg/kg) and morphine (1.88-15.0 mg/kg) decreased the sensitivity measures (A' and SI) but did not consistently affect the response bias measures (B&quot; and RI). The probability of response repetition was increased by d-amphetamine and was not affected by morphine. It is concluded that the response bias measure B&quot;, derived from signal detection theory, and the empirical response bias measure RI, do not discriminate between the different ways in which d-amphetamine and morphine affect discriminative responding, under the conditions of this study.<p /><p>Language: en</p>",
