The impact of monetary stimuli on object-based attention

Previous research has implied that monetary reward to target location (a reward for spatial properties) can affect object-based attention, but no study has directly investigated the influence of monetary objects (a reward for object properties) on object-based attention. Thus, it is unclear whether and how monetary objects can affect object-based attention. To experimentally investigate this problem, this study adapted the well-established two-rectangle paradigm. In Experiment 1, either two 100-yuan notes or two 1-yuan notes were presented to participants. We found an object-based effect with faster responses to targets at an uncued position on the cued object compared to those at an equidistant position on the uncued object; the effect was similar in 100-yuan and 1-yuan note trials. In Experiment 2, two notes (one 100-yuan and one 1-yuan) were simultaneously presented to participants, and cue location (100-yuan, 1-yuan) was manipulated. We found a greater object-based effect when the cue appeared on the 100-yuan note than on the 1-yuan note. These results suggest that the rewarding property of objects can affect object-based attention by means of altering object salience.     

The prevalence of cognitive disengagement in automobile crashes

The current study analysed crashes identified in a large-scale naturalistic driving database to assess the prevalence of cognitive disengagement (i.e., purely cognitive distraction and mind wandering/microsleep) or episodes wherein the driver did not look away from the roadway during secondary task completion or wherein another clearly observable contributing crash factor was not present, and the driver's reaction to the crash showed symptoms of cognitive disengagement. The study found that <1% (95% CI [0.45, 1.66]) of higher severity crashes had a potential contributing crash factor of mind wandering/microsleep; ~1.5% (95% CI [0.83, 2.32]) had a potential contributing factor of purely cognitive distraction. The results suggest a relatively low prevalence of cognitive disengagement among automotive crashes compared with visual/manual secondary tasks. However, the current methodology is limited in that it does not account for instances where cognitive disengagement, in combination with other factors, may have led to crashes, potentially leading to conservative estimates.     

父母教养方式影响青少年感恩:心理特权和观点采择的中介作用

本研究以482名中学生为被试,采用问卷法探究父母情感温暖、父母拒绝以及父母过度保护的教养方式、心理特权以及观点采择对青少年感恩的影响机制。结果表明：（1）父母情感温暖显著正向预测青少年感恩,父母拒绝显著负向预测青少年感恩;（2）观点采择在三种父母教养方式与青少年感恩之间起中介作用,心理特权只在父母拒绝和父母过度保护与青少年感恩之间起中介作用。这表明父母教养方式通过观点采择和心理特权的中介作用影响青少年感恩,但是不同的教养方式作用路径不同。     

"灵魂"出壳之谜

最近,我的一位与我有桃园结义般友情的朋友死了,我抚尸大恸,不肯骤舍,此情此景使在场的人接连陪了几场落泪。最令我感动的是那位被丧家请来的阴阳师,他出于赞叹友谊的魅力,突然间要我接受真情考验,说,你们的感情既然如此深厚,灵魂出走时我让你俩最后见上一面,因为此时他的刚刚出壳的灵魂正隐藏在某个角落里,出殡前的头一天离家,走的是东南方向,灵魂升腾时将触及屋前那个袅然升起的树枝,你看就是那个,在老杈股旁边悄然独出的那枝!我和在场的人对屋前这株梨树突然发生了兴趣,这是株百年老树,目睹过在他的身边居住过的几代甚至十几代人,老树无…     

A memory-based, Simon-like, spatial congruence effect: Evidence for persisting spatial codes

The Simon effect refers to the finding that in a task where stimulus location is irrelevant, reaction time is faster when stimulus and response locations are congruent than when they are not. Dominant theories of the Simon effect have generally attributed this spatial congruence effect to a spatial code automatically generated upon stimulus presentation. A common assumption of these theories is that this spatial code decays in less than a few hundred milliseconds following stimulus onset. We report two working-memory experiments suggesting a reexamination of this assumption—a Simon-like spatial congruence effect persisted over a delay of as long as 2400 ms. We propose that, in addition to generating short-lived perceptual codes, spatial information may be coded in working memory as part of the context associated with stimulus events. When reactivated by cues from the original event, such information may influence response selection and produce spatial congruence effects (in this case, positive when participants made a “yes” response and negative when they made a “no” response).     

两种科学观:本质主义与非本质主义

科学是现代文明的主要智力源泉,现代科技则是现代文明发展的主动力,是现代文明最炫目的一部分。如果说现代文明已陷入深重危机(如全球性生态危机、核战争的潜在危险和现代生物技术以及人工智能技术的应用风险),那么这深重危机与现代科技的理念、方法和发展方向直接相关。反思现     

Useful predictors of counseling effectiveness

A summary is given of research on characteristics of effective counselors in terms of indicators that show promise as predictors of counselor effectiveness as well as indicators that appear to possess little or no such promise. Recommendations are made for the use of these findings in research and practice.
