一只鸽子学习一个任意的列表，形成组块的最小条件是什么？实验1比较了两种类型的组块表（每种组块表由颜色和无色几何形式组成）的获得：A→ B→ C→ D′→ E′（或A′→ B′→ C′→ D→ E）和A→ B→ C′→ D′→ E′（或A′→ B′→ C→ D→ E）。第一种类型的列表比第二种更快地获得。然而，在这两个列表中，组块的证据直到训练的四个项目阶段才出现（例如，在一类列表项目的末尾停顿）。在实验2中，组块出现在颜色和形状分离的四项列表（A→ B→ C′→ D′和A′→ B′→ C→ D）中，但不出现在两种类型的项目散布的列表（A→ B′→ C′→ D和A′→ B→ C→ D′）中。在实验1中，组块的证据（在组块边界暂停）没有出现，直到第四个项目被添加。
What are the minimal conditions for the formation of chunks by a pigeon learning an arbitrary list? Experiment 1 compared the acquisition of two types of chunkable list (each composed of colors and achromatic geometric forms): A→ B→ C→ D′→ E′(or A′→ B′→ C′→ D→ E) and A→ B→ C′→ D′→ E′(or A′→ B′→ C→ D→ E). The first type of list was acquired more rapidly than the second. On both lists, however, evidence of chunking did not emerge until the four-item phase of training (eg, pauses at the end of one category of list item). In Experiment 2, chunking was shown to occur on four-item lists in which colors and forms were segregated (A→ B→ C′→ D′ and A′→ B′→ C→ D), but not on lists in which the two types of items were interspersed (A→ B′→ C′→ D and A′→ B→ C→ D′). As in Experiment 1, evidence of chunking (pauses at chunk boundaries) did not appear until the fourth item was added.
