    Description / Table of Contents: Behaviorism has been the dominant force in the creation of modern American psychology. However, the unquestioned and unquestioning nature of this dominance has obfuscated the complexity of behaviorism. Control serves as an antidote to this historical myopia, providing the most comprehensive history of behaviorism yet written. Mills successfully balances the investigation of individual theorists and their contributions with analysis of the structures of assumption which underlie all behaviorist psychology, and with behaviorism's role as both creator and creature of larger American intellectual

    Notes: Abstract. We have examined unfertilised oocytes and their first polar bodies (PBs) to determine the way in which the frequency of whole chromosome imbalance compares with that involving single chromatids and whether the precocious separation of chromatids prior to anaphase I affects all pairs of chromosomes. We have applied the technique of fluorescent in situ hybridisation in a three-stage method by using locus-specific probes for chromosomes 13 and 21 and α-satellite probes for chromosomes 1, 9, 16, 18 and X to determine the chromosome status of oocytes and their PBs. We obtained analysable results from 127 oocytes and 57 PBs from 72 patients of average age 33 years. Six oocytes and three PBs had extra signals but, of these, three were derived from a single patient, aged 26. Anomalies were seen in chromosomes 13, 16, 18, X and, notably, 21 but none were observed in chromosomes 1 and 9. Half of the anomalies involved additional chromatids rather than whole chromosomes. Since particular chromatids were found to be prematurely separated in the metaphase II oocyte, this may provide further evidence for an additional mechanism of maternal aneuploidy that operates at anaphase II. Detailed analyses of both oocytes and PBs have elucidated possible mechanisms leading to aneuploid gametes in this group of patients with fertility problems.

    Notes: Abstract The effects of increasing the level of ovarian stimulation on preimplantation embryonic development were assessed using a mouse in vitro fertilization system. When F1 hybrid (C57BL/6 × CBA/Ca) mice received a single injection of 5 IU pregnant mare's serum gonadotropin (PMSG) followed 60 hr later by 5 IU human chorionic gonadotropin (hCG) approximately 50% of the resultant postovulatory oocytes developed to the blastocyst stage following in vitro fertilization. Increasing the single dose of PMSG to 10 or 15 IU resulted in significant reductions in the frequency of development to the blastocyst stage. When one or two additional doses of 5 IU PMSG were administered 24 and 48 hr after an initial injection of 5 IU, lower frequencies of oocytes with the potential for full preimplantation development were again observed. This reduction in gamete quality was significantly greater when the final dose of PMSG was administered only 12 hr prior to hCG. The results suggest that excessive gonadotropin stimulation may compromise the quality of the preimplantation embryos obtained following in vitro fertilization and that the timing of gonadotropin administration may also be critical.

    Notes: Abstract The early embryonic development of in vitro fertilized oocytes was assessed following superovulation in F1 hybrid C57BL/6×CBA/Ca mice. Decreasing the time interval between the administration of constant doses of pregnant mare's serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) resulted in decreases in the frequency of development to the blastocyst stage but had no significant effect on development to the two-cell stage. Preincubation of postovulatory oocytes in vitro prior to insemination did not compensate for the reduced preovulatory development in vivo but resulted in decreases in the frequency of development to the blastocyst stage. The results indicate that inadequate preovulatory development of superovulated mouse oocytes can adversely affect the preimplantation development of in vitro fertilized embryos in the absence of a visible inhibitory effect on development to the two-cell stage and also that preincubation of postovulatory oocytes in vitro prior to fertilization reduces subsequent developmental capacity.
