Habituation contributes to within-session changes in free wheel running.

Three experiments tested the hypothesis that habituation contributes to the regulation of wheel running. Rats ran in a wheel for 30-min sessions. Experiment 1 demonstrated spontaneous recovery. Rats ran more and the within-session decreases in running were smaller after 2 days of wheel deprivation than after 1 day. Experiment 2 demonstrated dishabituation. Running rate increased immediately after the termination of a brief extra event (application of the brake or flashing of the houselight). Experiment 3 demonstrated stimulus specificity. Rats completed the second half of the session in either the same wheel as the first half, or a different wheel. Second-half running was faster in the latter case. Within-session patterns of running were well described by equations that describe data from the habituation, motivation, and operant literatures. These results suggest that habituation contributes to the regulation of running. In fact, habituation provides a better explanation for the termination of wheel running than fatigue, the variable to which this termination is usually attributed. Overall, the present findings are consistent with the proposition that habituation and sensitization contribute to the regulation of several forms of motivated behavior.     

Contractualism and Global Economic Justice

This article examines Rawls's and Scanlon's surprisingly undemanding contractualist accounts of global moral principles. Scanlon's Principle of Rescue requires too little of the world's rich unless the causal links between them and the poor are unreliable. Rawls's principle of legitimacy leads him to theorize in terms of a law of peoples instead of persons, and his conception of a people leads him to spurn global distributive equality. Rawls's approach has advantages over the cosmopolitan egalitarianism of Beitz and Pogge. But it cannot generate principles to regulate the entire global economic order. The article proposes a new cosmopolitan economic original position argument to make up for this lack in Rawls's Law of Peoples.     

4—6岁幼儿空间方位传递性推理能力的发展

该研究旨在探查4、5、6岁幼儿空间上下和前后方位传递性推理能力的发展水平及不同实验条件(一致、模糊、冲突)下儿童的传递性推理能力。为了尽量降低记忆对推理的影响,要求幼儿在前提呈现的条件下按前提方位关系进行传递性推理操作。被试为幼儿园4、5、6岁组儿童各24人,其中男女各半。主要结果表明：4岁幼儿开始萌发空间前后和上下方位的传递性推理能力;从4岁到6岁,“上下”方位传递性推理能力的发展优于“前后”方位;4—6岁幼儿还不能完全摆脱知觉干扰因素的影响,形成稳定的传递性推理能力。     

Dissociation of short- and long-term face memory: evidence from long-term recency effects in temporal lobe epilepsy

We tested whether memory deficits in temporal lobe epilepsy (TLE) are better described by a single- or dual-store memory model. To this aim, we analyzed the influence of TLE and proactive interference (PI) on immediate and 24-h long-term recency effects during face recognition in 16 healthy participants and 18 right and 21 left non-surgical TLE patients. PI in healthy participants or TLE erased the long-term recency effect, but left the immediate recency effect unaffected. Although the immediate recency effect was still visible in right TLE patients, the number of detected recency items during immediate recognition was decreased in right TLE compared to left TLE. Right TLE was also related to decreased detection of pre-recency items during delayed recognition compared to left TLE, and decreased detection of pre-recency items during immediate recognition under PI. The results show that the temporal lobes are necessary for the long-term recency effect, but not for the immediate recency effect, and thus speak for a dissociation of short- and long-term memory for faces. Right TLE is related to more severe long-term memory deficits than left TLE and is also related to additional short-term memory deficits for faces.

《管子》为杂家著作考

《管子》书非管仲所著已成学界公论,但其具体著者和成书年代当前却无一致认识,同时《管子》书的学派归属问题也存在着很大争议。笔者认为,《管子》为齐国稷下部分学者集体创作而成,其成书于战国晚期。《管子》的学派归属既非"齐法家",亦不是"道家黄老",而是先秦杂家。《管子》对于中国哲学、中国封建政治文化的发展起了重要的作用,它所体现出的"和而不同"的文化观对当代文化现代化的建设具有时代的价值。     

The role of Hebrew letter names in early literacy: the case of multiphonemic acrophonic names

English-speaking children spell letters correctly more often when the letters' names are heard in the word (e.g., B in beach vs. bone). Hebrew letter names have been claimed to be less useful in this regard. In Study 1, kindergartners were asked to report and spell initial and final letters in Hebrew words that included full (CVC), partial (CV), and phonemic (C) cues derived from these letter names (e.g., kaftor, kartis, kibepsilonl, spelled with /kaf/). Correct and biased responses increased with length of congruent and incongruent cues, respectively. In Study 2, preschoolers and kindergartners were asked to report initial letters with monosyllabic or disyllabic names (e.g., /kaf/ or /samepsilonx/, respectively) that included the cues described above. Correct responses increased with cue length; the effect was stronger with monosyllabic letter names than with disyllabic letter names, probably because the cue covered a larger ratio of the letter name. Phonological awareness was linked to use of letter names.     

The effects of mindfulness on executive processes and autobiographical memory specificity

Previous studies have found that mindfulness training reduces overgeneral memories and increases autobiographical memory specificity (e.g., [Williams, J. M. G., Teasdale, J. D., Segal, Z. V., & Soulsby, J. (2000). Mindfulness-based cognitive therapy reduces overgeneral autobiographical memory in formerly depressed patients. Journal of Abnormal Psychology, 109, 150-155]). However, little work has investigated the mechanisms underlying this effect. The present study explored the role of executive processes as a mediator of MBCT effects in an unselected sample. An autobiographical memory task, a cognitive inhibition task, a motor inhibition task, a cognitive flexibility task and a motor flexibility task were administered before and after intervention. Compared to matched controls, MBCT participants showed increased autobiographical memory specificity, decreased overgenerality, and improved cognitive flexibility capacity and capacity to inhibit cognitive prepotent responses. Mediational analyses indicated that changes in cognitive flexibility partially mediate the impact of MBCT on overgeneral memories. Results are discussed in terms of Conway's [2005. Memory and the self. Journal of Memory and Language, 53, 594-628] autobiographical memory model.
