Real-world scenes elicit anticipatory representation in long-term memory (LTM) and working memory (WM) resulting in boundary extension (BE). Would the same results hold for nonscene patterns of objects? In Experiment 1A (LTM-paradigm), 15 regular or 15 random object-patterns were sequentially presented (10 s each); a boundary-rating-task followed. Both pattern-types elicited BE. Surprisingly, regularity (greater pattern predictability) did not enhance BE. Instead, random patterns more consistently yielded BE. Perhaps random object-groupings enhance BE (e.g., more scene-like). Objects within regular patterns were colored to create object-groupings; this increased BE compared to regular patterns without color groups, but only in 1 of the 2 tests (Experiment 1B, LTM-paradigm). In Experiment 2 (WM-paradigm), a briefly presented pattern, regular or random, was followed by a 2-s masked interval and a boundary-rating-task on each trial. Here, results reversed: patterns now elicited boundary restriction (whether or not a concurrent task had been presented to prevent verbalization). Under time pressure, without real-world layout and meaning, pattern elements may not have cohered into a unified expanse, failing to elicit BE and resulting in loss of peripheral content. We propose 2 classes of visual content that may determine anticipatory representation: content that embellishes space versus content that defines space.

规则和随机模式的预期记忆。

真实世界的场景会在长期记忆(LTM)和工作记忆(WM)中引起预期的表示,从而导致边界扩展(BE)。物体的非场景模式会得到相同的结果吗?在实验1A(LTM范例)中,依次显示了15个常规或15个随机对象模式(每个10 s);接下来是边界评估任务。两种模式类型都引发BE。出人意料的是,规律性(更大的模式可预测性)并没有增强BE。相反,随机模式更一致地产生BE。也许随机的对象分组会增强BE(例如,更类似于场景)。常规模式中的对象被着色以创建对象分组。与没有颜色组的常规图案相比,BE增加了,但是只有两种测试中的一种(实验1B,LTM范例)。在实验2(WM范例)中,简要介绍了一种模式,定期或随机,然后在每个试验中加上2秒的屏蔽时间间隔和边界评估任务。在这里,结果颠倒了:模式现在引起了边界限制(无论是否提出并发任务来防止口头表达)。在时间压力下,如果没有现实世界的布局和含义,图案元素可能无法连成一个统一的区域,从而无法引发BE并导致外围内容的丢失。我们建议可以确定预期表示形式的两类视觉内容:点缀空间的内容与定义空间的内容。(PsycInfo数据库记录(c)2020 APA,保留所有权利)。模式现在引起了边界限制(是否提出了并发任务以防止口头表达)。在时间压力下,如果没有现实世界的布局和含义,图案元素可能无法连成一个统一的区域,从而无法引发BE并导致外围内容的丢失。我们建议可以确定预期表示形式的两类视觉内容:点缀空间的内容与定义空间的内容。(PsycInfo数据库记录(c)2020 APA,保留所有权利)。模式现在引起了边界限制(是否提出了并发任务以防止口头表达)。在时间压力下,如果没有现实世界的布局和含义,图案元素可能无法连成一体,无法引起BE并导致外围内容丢失。我们建议可以确定预期表示形式的两类视觉内容:点缀空间的内容与定义空间的内容。(PsycInfo数据库记录(c)2020 APA,保留所有权利)。点缀空间的内容与定义空间的内容。(PsycInfo数据库记录(c)2020 APA,保留所有权利)。点缀空间的内容与定义空间的内容。(PsycInfo数据库记录(c)2020 APA,保留所有权利)。
