BEHAVIOR ANALYSIS in NEUROSCIENCE - PART 9

Tỷ lệ phần trăm của những con chuột trong mỗi nhóm đạt được các tiêu chí autoshaping phát ra 6 hoặc nhiều hơn giảng dạy tiếng Anh trong thời gian 2 của 3 phiên tiếp giáp. Phần 3 (hình 14.3A) tỷ lệ ph | FIGURE 14.3 Percentage of rats in each group achieving the autoshaping criterion of emitting 6 or more ELT during 2 of 3 contiguous sessions. By Session 3 Figure 14.3A the percentage of rats in the D1G achieving the criterion was significantly below the CG D13G 0 vs. 44 p 0.05 . These values increased to 11 vs. 78 during Session 6 and 22 vs. 89 for Session 9 p 0.01 in both cases . By Session 12 the percentage achieving criterion for these two groups was the same as for Session 9 and is depicted in Figure 14.3B. None of the other groups were significantly different from the control group using this criterion analysis. IV. Discussion The results of this experiment indicate that as animals learn to form the association between lever extension retraction and food pellet delivery during autoshaping they become increasingly resistant to the behaviorally toxic effects of physostigmine. As shown above only the D1G and D4G groups were significantly suppressed compared to the D8G on more than the first day that each of these groups received physostigmine. The D8G group was significantly suppressed on only the first day of its treatment with physostigmine and it took 4 sessions and a reduction of the dose of physostigmine to 0.067 mg kg before the D4G group returned to levels of responding not different from the CG D13Gs. The D1G group remained suppressed virtually throughout the study even after their dose was also reduced to one third for Session 8 and beyond and even on Session 13 when they received a saline injection.
