Memory for time: How people date events

The effect of different formats on the accuracy of dating news and the distribution of personal events was examined in four conditions. In the first, participants had to date events in the absolute time format (e.g., "July 2004"), and in the second, they had to date events in the relative time format (e.g., "3 weeks ago"). In the other conditions, they were asked to choose between the two formats. We found a small backward telescoping effect for recent news events and a large forward telescoping effect for remote events. Events dated in the absolute time format were more accurate than those dated in the relative time format. Furthermore, participants preferred to date news events with the relative time format and personal events with the absolute time format, as well as preferring to date remote events in the relative time format and recent events in the absolute time format.     

Modulation sensitivity in the perceptual organization of speech

In a spoken utterance, a talker expresses linguistic constituents in serial order. A listener resolves these linguistic properties in the rapidly fading auditory sample. Classic measures agree that auditory integration occurs at a fine temporal grain. In contrast, recent studies have proposed that sensory integration of speech occurs at a coarser grain, approximate to the syllable, on the basis of indirect and relatively insensitive perceptual measures. Evidence from cognitive neuroscience and behavioral primatology has also been adduced to support the claim of sensory integration at the pace of syllables. In the present investigation, we used direct performance measures of integration, applying an acoustic technique to isolate the contribution of short-term acoustic properties to the assay of modulation sensitivity. In corroborating the classic finding of a fine temporal grain of integration, these functional measures can inform theory and speculation in accounts of speech perception.     

The Twisted Relationship Between School Spending and Academic Outputs: in Search of a New Metaphor

In this commentary we explore both putative and potential relationships between school funding and educational outcomes, for which numerous indices and variables have been examined during the past two decades. We conclude that despite large increases in real dollars, there is no readily discernable link between inputs and outputs, although when statistical control is exerted over prior ability, school mix, and teacher turn-over, certain causal inferences appear warranted. However, it can be argued that the dominant analogy should be reconsidered, and schools serving large numbers of needy children may require higher inputs to keep from further declines, much like certain departments of a hospital require disproportionately more resources than others in order to be successful because they deal with problems that are more severe.     

“Can We Talk?”: Boundary Crossing and Sexual Misconduct in Seminary Teaching

This article explores a variety of personal and professional boundary issues encountered by seminary faculty. The authors contend that boundary crossing is inevitable in contemporary theological education, which is structured such that professors engage in multiple roles with students as they attend to the education of the whole person. Guidelines are reviewed for minimizing risk to students and professors. Topics include life as a community member, student‐faculty friendship, and romantic relationships. Attention to work/life balance is seen as critical to the prevention of misconduct. The article ends with a call for continued conversation as well as institutional accountability and change.     

目的、意向和意识

本文提出了一个意向性目标搜寻的计算机模型,它有两个部分,静态部分包括一个目标表征和到达这个目标的程序。动态部分是一个感觉输入、中间信息加工,行为输出的重复的反馈循环。人类意向必然伴有意识,但机器人则可能无意识而有意向。 利用目标搜寻系统机器人模型,我们对目标搜寻系统的目的连续统下了定义;这个连续统从简单的直接反应系统一直到意向性系统。对这个目的连续统有两种传统的解释:一是柏拉图、亚里士多德和普罗提诺的终极原因理论,二是希腊原子论者和现代进化生物学家的还原主义学说。本文评价了这些学说。 本文考察了几种类型的意识机能,提出了以自动机为依据的意识理论,比较了人类和计算机。从计算机结构的角度来看,人类意识是一类特殊的计算机控制系统。
