Moral Feedback and Motivation: Revisiting the Undermining Effect

Social psychologists have evidence that evaluative feedback on others’ choices sometimes has unwelcome negative effects on hearers’ motivation. Holroyd’s article (Holroyd J. Ethical Theory Moral Pract 10:267–278, 2007) draws attention to one such result, the undermining effect, that should help to challenge moral philosophers’ complacency about blame and praise. The cause for concern is actually greater than she indicates, both because there are multiple kinds of negative effect on hearer motivation, and because these are not, as she hopes, reliably counteracted by implicit features of praise and blame. The communicative ideal that she articulates does point us in the right direction, but it requires further elaboration. Once it is spelled out, we find that realizing this ideal, in light of the empirical research, requires rethinking the role of verdict-like judgments within moral feedback.

Food and token quantity discrimination in capuchin monkeys (<Emphasis Type="Italic">Cebus apella</Emphasis>)

Quantity discrimination is adaptive in a variety of ecological contexts and different taxa discriminate stimuli differing in numerousness, both in the wild and in laboratory settings. Quantity discrimination between object arrays has been suggested to be more demanding than between food arrays but, to our knowledge, the same paradigm has never been used to directly compare them. We investigated to what extent capuchin monkeys’ relative numerousness judgments (RNJs) with food and token are alike. Tokens are inherently non-valuable objects that acquire an associative value upon exchange with the experimenter. Our aims were (1) to assess capuchins’ RNJs with food (Experiment 1) and with tokens (Experiment 2) by presenting all the possible pair-wise choices between one to five items, and (2) to evaluate on which of the two proposed non-verbal mechanisms underlying quantity discrimination (analogue magnitude and object file system) capuchins relied upon. In both conditions capuchins reliably selected the larger amount of items, although their performance was higher with food than with tokens. The influence of the ratio between arrays on performance indicates that capuchins relied on the same system for numerical representation, namely analogue magnitude, regardless of the type of stimuli (food or tokens) and across both the small and large number ranges.     

The ELCA at 20 Years: Flunking the Theological Test

Abstract : This article deals with four theological issues at the forefront of controversy in the ELCA. They are: 1) the naming of God; 2) the unique place of Jesus in the world's salvation; 3) the authority and interpretation of the Bible; 4) the place of the law in theological ethics. The response to these issues holds the key as to whether or to what extent the ELCA will be faithful to its confessional commitment or become just another variety of liberal Protestantism.     

Values,achievement goals,and individual‐oriented and social‐oriented achievement motivations among Chinese and Indonesian secondary school students

This study examined how values related to achievement goals and individual‐oriented and social‐oriented achievement motivations among secondary school students in China (N = 355) and Indonesia (N = 356). Statistical comparisons showed the Chinese students endorsed more strongly than the Indonesian students on self‐direction and hedonism values, individual‐oriented achievement motivation, and mastery‐approach goals. Conversely, the Indonesian students endorsed more strongly than their Chinese counterparts on security, conformity, tradition, universalism and achievement values, social‐oriented achievement motivation, and performance‐approach and mastery‐avoidance goals. Values explained a significant amount of the variance in almost all of the dimensions of motivation. Etic and emic relationships between values and achievement motivations were found.     

The application of the first order system transfer function for fitting the 3-arm radial maze learning curve

A mathematical model is described based on the first order system transfer function in the form Y=B3∗exp(−B2∗(X−1))+B4∗(1−exp(−B2∗(X−1))), where X is the learning session number; Y is the quantity of errors, B2 is the learning rate, B3 is resistance to learning and B4 is ability to learn. The model is tested in a light-dark discrimination learning task in a 3-arm radial maze using Wistar and albino rats. The model provided good fits of experimental data under acquisition and reacquisition, and was able to detect strain differences among Wistar and albino rats. The model was compared to Rescorla-Wagner, and was found to be mutually complementary. Comparisons with Tulving’s logarithmic function and Valentine’s hyperbola and the arc cotangent functions are also provided. Our model is valid for fitting averaged group data, if averaging is applied to a subgroup of subjects possessing individual learning curves of an exponential shape.     

THE PUZZLE OF FALLIBLE KNOWLEDGE

Abstract: Although the fallible/infallible distinction in the theory of knowledge has traditionally been upheld by most epistemologists, almost all contemporary theories of knowledge claim to be fallibilist. Fallibilists have, however, been forced to accommodate knowledge of necessary truths. This has proved to be a daunting task, not least because there is as yet no consensus on how the fallible/infallible divide is to be understood. In this article, after examining and rejecting a number of representative accounts of the notion of fallible knowledge, I argue that the main problems with these accounts actually stem from the very coherence of that notion. I then claim that the distinction is best understood in terms of the externalist/internalist conceptions of knowledge. Finally, I seek to garner some independent support for the proposal by highlighting some of its consequences, including its surprising bearing on certain recent and seemingly distant controversies involving issues in epistemology and philosophy of mind.     

Bayesian IRT Guessing Models for Partial Guessing Behaviors

According to the recent Nation’s Report Card, 12th-graders failed to produce gains on the 2005 National Assessment of Educational Progress (NAEP) despite earning better grades on average. One possible explanation is that 12th-graders were not motivated taking the NAEP, which is a low-stakes test. We develop three Bayesian IRT mixture models to describe the results from a group of examinees including both nonguessers and partial guessers. The first assumes that the guesser answers questions based on his or her knowledge up to a certain test item, and guesses thereafter. The second model assumes that the guesser answers relatively easy questions based on his or her knowledge and guesses randomly on the remaining items. The third is constructed to describe more general low-motivation behavior. It assumes that the guesser gives less and less effort as he or she proceeds through the test. The models can provide not only consistent estimates of IRT parameters but also estimates of each examinee’s nonguesser/guesser status and degree of guessing behavior. We show results of a simulation study comparing the performance of the three guessing models to the 2PL-IRT model. Finally, an analysis of real data from a low-stakes test administered to university students is presented.

内隐序列学习意识的具身机制

内隐序列学习意识已有三类理论如全局工作平台理论、神经可塑性理论、新异刺激理论都忽略了身体感受的关键因素, 难以揭示意识产生的根本原因。具身意识理论和研究发现, 运动/情感镜像神经元系统及与自我、认知控制系统的交互, 是初级/高级意识产生的本源, 但未涉及内隐序列学习规则意识这个对人类学习认知至关重要的领域。内隐序列学习研究实质上已接近揭示其学习机制正是感知觉运动具身学习, 其意识机制很可能是感知觉运动/情感具身意识, 并且其意识加工脑区与具身意识脑区有关键重合。未来研究可采用Granger因果大脑网络技术证明内隐序列学习意识的具身本源, 并考察已有三类意识理论的具身基础, 以及探索意识影响因素的具身机制。     

疾病的心理防御：人类如何应对病菌威胁

病菌和传染病构成的选择压力导致动物进化出了身体免疫以及行为免疫反应。而人类的大脑进化促使他们发展出了最为复杂的行为免疫系统。很早开始, 我们就依赖自身的各种行为免疫反应抵抗病菌。当这些疾病抵御机制跟群体生活协同进化之后, 我们的很多社会行为和态度都具有了减少疾病感染的功能, 它们包括对外群体成员的偏见、歧视, 以及对内群体成员的从众、服从。而更高层次的文化差异比如集体主义-个人主义, 至少部分原因是要管理与疾病感染有关的风险。本篇综述讨论了与抵御病菌威胁有关的社会行为、态度和其他心理现象。
