Escape learning as a function of amount of shock reduction.
Several studies (Crespi, 1942; Zeaman, 1949) have shown that performance in instrumental appetitive conditioning is directly related to the magnitude of reward contingent upon the response. Moreover, these studies have indicated that shifts in amount of reinforcement (amount of food or water) lead to rapid and appropriate changes in performance level. The results of a study by Campbell and Krae...
متن کاملResponse Force as a Function of Amount of Reinforcement.
5 groups of 6 rats each were trained to press an isometric lever and were rewarded with either 1, 2, 3, 4, or S 20-mg. pellets on responses meeting or exceeding an 8-gm. force criterion. After 10 Acquisition sessions all Ss were shifted to 3 pellets for 6 further sessions and then received 2 Extinction sessions. Both force and variability of bar pressing varied inversely with amount of reward b...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Amniocytes can serve a dual function as a source of iPS cells and feeder layers
Clinical barriers to stem-cell therapy include the need for efficient derivation of histocompatible stem cells and the zoonotic risk inherent to human stem-cell xenoculture on mouse feeder cells. We describe a system for efficiently deriving induced pluripotent stem (iPS) cells from human and mouse amniocytes, and for maintaining the pluripotency of these iPS cells on mitotically inactivated fe...
متن کاملtranslating allusive devices:a survey of a portrait of the artist as a young man by james joyce
تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
