“…Experiment 1 showed that the prime diagnosticity had a clear effect on identification performance but that discounting as a 3 For the negative prime diagnosticity, we found a marginally significant interaction between prime type, prime duration, and block: F(2, 162) ϭ 3.93, MSE ϭ 0.02, p ϭ .05 (Huynh-Feldt ε ϭ .53 corrected; Huynh & Feldt, 1976), but the effect was very small ( p 2 ϭ .05). function of prime duration remained a critical mechanism.…”

“…As is evident from the bottom two panels of Figure 9, prime diagnosticity also had a strong influence on identification performance when it was associated with prime duration, even though the overall prime diagnosticity was neutral when collapsing across prime duration. A 4 (diagnosticity condition) ϫ 3 (prime type) ϫ 2 (prime duration) ANOVA revealed significant main effects of prime type, F(2, 228) ϭ 55.05, MSE ϭ 1.03, Huynh-Feldt ε (.57) corrected p Ͻ .01 (Huynh & Feldt, 1976), and priming duration, F(1, 114) ϭ 203.72, MSE ϭ 1.85, p Ͻ .01. As in the previous experiments, the interaction of prime type and prime duration was also significant, F(2, 228) ϭ 242.25, MSE ϭ 3.07, Huynh-Feldt ε (.47) corrected p Ͻ .01, as was the interaction between these two factors and the diagnosticity condition, F(6, 228) ϭ 23.42, MSE ϭ 0.30, Huynh-Feldt ε (.47) corrected p Ͻ .01.…”

“…It is evident from the figure that the results for the two diagnosticities are virtually identical, and a 3 (prime type) ϫ 2 (prime duration) ϫ 2 (prime diagnosticity) ANOVA confirmed that no effects involving prime diagnosticity were significant. As in previous experiments, the effects of prime type, F(2, 80) ϭ 13.06, MSE ϭ 0.45, Huynh-Feldt ε ϭ .71; prime duration, F(1, 40) ϭ 50.99, MSE ϭ 1.49; and their interaction, F(2, 80) ϭ 86.52, MSE ϭ 2.35, Huynh-Feldt ε ϭ .69 ( p Ͻ .01 for all tests; HuynhFeldt ε corrected where applicable; Huynh & Feldt, 1976) were all significant.…”

The authors conducted 4 repetition priming experiments that manipulated prime duration and prime diagnosticity in a visual forced-choice perceptual identification task. The strength and direction of prime diagnosticity produced marked effects on identification accuracy, but those effects were resistant to subsequent changes of diagnosticity. Participants learned to associate different diagnosticities with primes of different durations but not with primes presented in different colors. Regardless of prime diagnosticity, preference for a primed alternative covaried negatively with prime duration, suggesting that even for diagnostic primes, evidence discounting remains an important factor. A computational model, with the assumption that adaptation to the statistics of the experiment modulates the level of evidence discounting, accounted for these results.

“…ICGU was measured in seven control and eight treated animals and ICBF in ten control animals and nine treated animals. While there are insufficient data to carry out a full multivariate profile analysis, a cautious log (LCGUl univariate approach is possible (Geisser and Green house, 1958;Huynh and Feldt, 1976). The effect of raphe stimulation has resulted in a shift of the data points to the right.…”

“…Repeated measures analyses of variance were conducted with medication condition (placebo, low and high dose naloxone) as the repeated measures factor and order of study sessions as a between-subjects factor. The Huynh-Feldt correction was used to determine significance values for repeated measures factors with more than two levels (Huynh and Feldt 1976). There were no main effects or interactions involving order of the study sessions.…”

Electroconvulsive therapy (ECT) is a highly effective treatment for major depression, but is also associated with characteristic cognitive side effects. Several reports document that endogenous opioids and their receptors are activated by electroconvulsive shock (ECS) and that naloxone in doses sufficient to block endogenous opioid receptors may reverse ECS-induced retrograde amnesia. This placebo-controlled, randomized, within-patient study was conducted to examine the potential of naloxone, given in doses sufficient to block opioid receptors (high dose)Electroconvulsive therapy (ECT) is a highly effective treatment for major depression and a variety of other disorders . However, the cognitive side effects of ECT are the major factor limiting its use. The cognitive consequences of ECT involve a period of postictal disorientation immediately following the induced seizure, as well as a pattern of more sustained neuropsychological deficits, principally anterograde and retrograde amnesia .There is substantial evidence that electroconvulsive shock (ECS) in experimental animals alters the concentrations of endogenous opioid peptides and the density of their receptors (Holaday et al. 1986). Opioids produce effects through at least three different receptors, , ␦ , and (Mansour et al. 1988; Quirion 1988). The receptors and ␦ have been extensively studied, and agonists at these receptors generally interfere with learning and memory, resulting in both anterograde and retrograde amnesia. The role of receptors in learning and memory is more complex. While agonists may impair memory in a dose-dependent fashion (Colombo et al., 1992), From they may also ameliorate memory deficits due to disruption of cholinergic transmission (Hiramatsu et al. 1996).Repeated ECS stimulates the release of proenkephalin and proopiomelanocortin ( ␤ -endorphin) (Tortella et al. 1989) and results in increased abundance of mRNA for preproenkepohalin in the hypothalmus and hippocampus (Yoshikawa et al. 1985;Xie et al. 1989;Simmons and Chavkin 1996). In the perforant pathway, projecting from entorhinal cortex to the hippocampal dentate gyrus, repeated ECS results in increased enkephalin immunostaining. In contrast, the release of dynorphin appears to be more complex. While increased dynorphin immunostaining has been found in limbic and basal ganglia structures, chronic ECS results in decreased levels in the mossy fiber axons of the dentate granule cells (Kanamatsu et al. 1986;Lasön et al. 1992). Overall, it appears that repeated ECS results in widespread increased synthesis and release in the proenkephalin system, and large decreases in the prodynorphin system in the hippocampus. Increased peptide synthesis and release may account for some findings of a sustained decreased density of and ␦ receptors following chronic ECS (Nakata et al. 1985;Crain et al. 1987). In humans, ECT has been found to result acutely in large increases in plasma ␤ -endorphin immunoreactivity (Alexopoulos et al. 1983;Weizman et al. 1987;Young et al. 1991).In a number of models...
