Self-control in rhesus macaques (Macaca mulatta): controlling for differential stimulus exposure

Previous research on self-control using macaques (Macaca fascicularis) showed these animals have a strong bias for a delayed, larger reinforcer (Self-control) over an immediate, smaller reinforcer (Impulsive). Typical studies of self-control have used a discrete trials methodology with a secondary discriminative stimulus during the delay periods. This results in a greater exposure to the stimulus representing the self-controlled option and may account for some of the early exclusive preference for self-control observed. The present experiment examined self-control bias in three rhesus macaques (Macaca mulatta) while controlling for differential durations of stimulus exposure. Subjects were presented stimuli via a computer monitor and made choices by touching the stimulus at which point both stimuli were removed for the delay periods. All three subjects displayed a nearly exclusive bias for the delayed, larger reinforcer self-control). These results are consistent with previous studies, despite the variations in methodology and species.     

PSYCHOTHERAPY AS PHASE-SPECIFIC INTERACTION

I am writing this paper to help myself, and hopefully some readers, to a better understanding of why some analysands in certain phases of the analysis develop the idea that they are homosexuals or that their analyst is homosexual. My basic thought is that even if these ideas have their individual roots and differ from case to case, they are also dependent on certain phenomena that are included in the analytic encounter and specified by different gender constellations constituting the analytic couple. I will present two examples from my own practice. From these two vignettes, I will draw some conclusions which are supported by my general psychoanalytic experience. The first example concerns male analysands. I have often seen male patients develop the fantasy that they “in reality” are homosexual. This fantasy is so common that it is a rule in my experience. I see it as a product of the fact that the psychoanalytic constellation consists, as in my case, of two men. The second example concerns female analysands. In a few cases with female analysands, I have seen the fantasy emerge that I, the analyst, am homosexual—a fantasy not seen in my male cases. Another difference is that I can't see this as a rule like the fantasy of the male analysands. In both the male and the female cases, I see the homosexual fantasies as a protection against discovery of the mother-transference to me. However, the fantasies have found different expressions depending on the specific gender constellation of the analytic couple: man and man and woman and man, respectively.
