当前俄罗斯维果茨基心理学思想研究的现状

当前俄罗斯维果茨基心理学思想研究的现状表现为：(1)对维果茨基心理学遗产的整理出版及其现代意义的研究;(2)维果茨基心理学思想发展阶段与维果茨基概念的逻辑结构研究;(3)对维果茨基心理学思想的发展;(4)俄罗斯心理学界对维果茨基及化历史心理学的批评。作认为,在当前俄罗斯对维果茨基的研究远不及西方“维果茨基热”有其重要的原因：当前俄罗斯的社会现实因素;西方维果茨基热是由于西方心理学自身的缺陷;与现代西方心理学的化转向有关。     

Effects of Interspersing Briefer Mathematics Problems on Assignment Choice in Students with Learning Disabilities

Within- and between-series designs were combined and used to evaluate the effects of interspersing briefer math problems (i.e., one-digit by one-digit multiplication, 1 × 1) with more time-consuming problems (i.e., two-digit by one-digit multiplication, 2 × 1) on time allocation to one of two concurrent computer-delivered mathematics computation assignments in four high school students with specific learning disabilities in mathematics. The computer presented students with a choice of 2 × 1 problems with 1 × 1 problems interspersed every third problem (i.e., experimental assignment) or 2 × 1 problems without interspersal (i.e., control assignment). Visual and statistical analysis showed that students allocated a greater percentage of their time to the interspersal assignments. These results support previous research on the matching law and problem completion rates and suggest that students' preference for assignments can be improved through the interspersal technique. Discussion focuses on future research and applied educational implications for curricula construction and task sequencing.

The Truth, Goodness, and Beauty of Darwinism

As a young proponent of "creation science," I rejected Darwinian biology as false, bad, and ugly. Now I defend Darwinism as true, good, and beautiful. Moreover, I now see Darwinism as compatible with the natural piety that arises as one moves from nature to nature's God.     

Global Justice: Is Interventionalism Desirable?

In 1994, the European Parliament published a resolution on the right of humanitarian intervention. Interestingly, the declaration maintains that such intervention is not in contradiction with international law, although it formulates the concept of right in a way that is translatable into the vocabulary of individual rights. I analyze some implications of the resolution for the mutual duties of states. I thereby focus my attention on two possible applications: by way of Rawls's duty of assistance and by way of the cosmopolitan theory of global distributive justice. I conclude that the latter theory promises better results for protecting individuals' basic rights, but I also show that it is at the cost of a strongly interventionist structure requiring a powerful supranational institution. Finally, I envision the conditions under which such an increase of interventionism in favor of human rights can be acceptable.     

Does It Make You Happy Feeling This Way? A Core Affect Account of Preference for Current Mood

Two experiments were conducted to investigate whether and how preference for current mood is related to the valence and activation dimensions of core affect. In Study 1, 100 undergraduates rated valence and activation of their naturally occurring current mood and preference for this mood. In Study 2, another 90 undergraduates performed the same ratings for various induced moods. The results showed as expected that preference for current mood is related to both valence and activation. Whereas the relation to valence is direct, the relation to activation is invertedly U-shaped with a maximum that increases with valence.     

专业人员价值取向的现状研究

对8省市的428位专业人员所进行的价值取向研究表明,我国专业人员的价值取向总体倾向是积极向上,与社会期待相符合的,重视社会责任、工作、公众利益、法律规范、感情和家庭的价值;性别、文化程度和年龄等人口统计学因素显著影响专业人员的价值取向的个别侧面,但收入水平、婚姻状况和家庭结构的作用不显著。     

An application of the matching law to evaluate the allocation of two- and three-point shots by college basketball players

We applied the matching equation to evaluate the allocation of two- and three-point shots by male and female college basketball players from a large Division 1 university. The matching law predicts that the proportion of shots taken from three-point range should match the proportional reinforcement rate produced by such shots. Thus, we compared the proportion of three-point shots taken relative to all shots to the proportion of three-point shots scored relative to all shots scored. However, the matching equation was adjusted to account for the greater reinforcer magnitude of the three-point basket (i.e., 1.5 times greater than the two-point basket reinforcer magnitude). For players with substantial playing time, results showed that the overall distribution of two- and three-point shots was predicted by the matching equation. Game-by-game shot distribution was variable, but the cumulative proportion of shots taken from three-point range as the season progressed was predicted almost perfectly on a player-by-player basis for both male and female basketball players.     

Three predictions of the economic concept of unit price in a choice context

Economic theory makes three predictions about consumption and response output in a choice situation: (a) When plotted on logarithmic coordinates, total consumption (i.e., summed across concurrent sources of reinforcement) should be a positively decelerating function, and total response output should be a bitonic function of unit price increases; (b) total consumption and response output should be determined by the value of the unit price ratio, independent of its cost and benefit components; and (c) when a reinforcer is available at the same unit price across all sources of reinforcement, consumption should be equal between these sources. These predictions were assessed in human cigarette smokers who earned cigarette puffs in a two-choice situation at a range of unit prices. In some sessions, smokers chose between different amounts of puffs, both available at identical unit prices. Individual subjects' data supported the first two predictions but failed to support the third. Instead, at low unit prices, the relatively larger reinforcer (and larger response requirement) was preferred, whereas at high unit prices, the smaller reinforcer (and smaller response requirement) was preferred. An expansion of unit price is proposed in which handling costs and the discounted value of reinforcers available according to ratio schedules are incorporated.
