The Paramenstruum And Negative Moods In Normal Young Women, Gregory J. Boyle

Gregory J. Boyle

The present study investigated the effects of depressogenic statements on 154 normal young women, in relation to the late luteal phase of the female monthly cycle (paramenstruum). The women were allocated to a depressive-induction group or to either of two non-treatment groups. Multivariate ANOVAs indicated that paramenstrual women given the depressogenic statements reported more negative post-induction mood states than did other women. Four of the 12 mood states measured by the Differential Emotions Scale (DES-IV) were significantly elevated for the paramenstrual women in the depressive-induction group only (viz. Sadness, Hostility, Fear and Shame subscales). It was concluded that paramenstrual women …

Some Parameters Of Behavioral Contrast And Allocation Of Interim Behavior In Rats, James Dougan, Frances Mcsweeney, Valeri Farmer

James Dougan

Two experiments examined the effects of baseline reinforcement rate and component duration on behavioral contrast and on re-allocation of interim behavior in rats. Positive behavioral contrast occurred during multiple variable-interval 10-second extinction (VI 10 EXT) after a multiple VI 10 VI 10 baseline condition, but not during multiple VI 60 EXT following multiple VI 60 VI 60 baseline. Component duration had no significant effect on contrast. These results differed from those found in studies of pigeons' key pecking. Contrast was accompanied by an increased rate of drinking in the changed component, but drinking in the constant component did not decrease. …

Variation In Herrnsein’S R0 As A Function Of Alternative Reinforcement Rate, James Dougan, Frances K. Mcsweeney

James Dougan

In a test of Herrnstein's (1970, 1974) equation for simple schedules, 15 pigeons pecked a key that produced food delivered according to variable-interval schedules. One group of birds was water deprived, and food-reinforced key pecking occurred in the presence of free water. Two other groups were not water deprived; water was present for one and absent for the other. As predicted by Herrnstein, the parameter r_o was significantly higher in the water-deprived group than in the two nondeprived groups. Contrary to Herrnstein's interpretation of r_o, the rate of drinking varied across schedules. Herrnstein's interpretation can be salvaged …
