Within-trial contrast: when is a failure to replicate not a type I error?

Abstract

Vasconcelos, Urcuioli, and Lionello-DeNolf (2007) report the results of five experiments that fail to replicate the results of our within-trial contrast study (Clement, Feltus, Kaiser, & Zentall, 2000) and suggest that our results may represent a Type I Error. We believe that this conclusion is not warranted because (a) there is considerable evidence in support of the effect and (b) the amount of training that they gave to their pigeons prior to test may not have been sufficient to observe the effect reliably. We suggest that when sufficient training is provided, reliable contrast can be found.

Within-trial contrast: when is a failure to replicate not a type I error?

1. "Work ethic" in pigeons: reward value is directly related to the effort or time required to obtain the reward.

2. Second-order contrast based on the expectation of effort and reinforcement.

3. Effect of response effort on the reward value of distinctively flavored food pellets.

4. Spontaneous alternation behavior.

5. Discriminative stimuli that follow a delay have added value for pigeons.

6. On science and the discriminative law of effect.

7. Pigeons shift their preference toward locations of food that take more effort to obtain.

8. Failure to replicate the 'work ethic" effect in pigeons.

9. Contrast and the justification of effort.

10. "Justification of effort" in rats: effects of physical and discriminative effort on reward value.

5. Failure to obtain value enhancement by within-trial contrast in simultaneous and successive discriminations.

6. Extensive training is insufficient to produce the work-ethic effect in pigeons.
