Evidence for a non-linguistic distinction between singular and plural sets in rhesus monkeys

Set representations are explicitly expressed in natural language. For example, many languages distinguish between sets and subsets (all vs. some), as well as between singular and plural sets (a cat vs. some cats). Three experiments explored the hypothesis that these representations are language specific, and thus absent from the conceptual resources of non-linguistic animals. We found that rhesus monkeys spontaneously discriminate sets based on a conceptual singular-plural distinction. Under conditions that do not elicit comparisons based on approximate magnitudes or one-to-one correspondence, rhesus monkeys distinguished between singular and plural sets (1 vs. 2 and 1 vs. 5), but not between two plural sets (2 vs. 3, 2 vs. 4, and 2 vs. 5). These results suggest that set-relational distinctions are not a privileged part of natural language, and may have evolved in non-linguistic species to support domain general quantitative computations.     

心理治疗效果评定量表（简式）在中、德应用的心理测量学研究

419名中国和德国被试参加了本研究,并回答了若干简式心理健康量表。所选的这套量表能对心理治疗不同阶段的效果（Howard’s阶段模型：重新认识期-转变期-康复期）进行测查。本研究目的在于考察这些简式量表能否用于认知-行为治疗跨文化培训项目中的质量管理。结果显示,这些量表在中德两种文化背景下都有很高的信度和效度（聚合效度和敏感性）。尽管项目间的高相关似乎提示心理健康模型只有一个维度,但探索性因素和理论分析则更支持心理健康是一个分为8个亚维度的模型,其中每个亚维度或者与基础情绪、或者与社会性情感相连关联。本文最后就研究结果及其对心理治疗质量控制的意义进行了详细讨论     

关于迁移理论的几点思考

迁移理论是教育心理学研究的一个重要内容,在其发展过程中不断有新观点产生。其间后继观点往往对先前观点有所臧否,这很正常。但后继观点本身以及对先前观点的评价并不一定无懈可击。桑代克对形式训练说的否定是值得商榷的;认知结构迁移理论否定相同因素是迁移的条件也值得讨论;相同因素应是迁移产生的最为重要的条件。     

Regularity re-revisited: modality matters

The issue of regular-irregular past tense formation was examined in a cross-modal lexical decision task in Modern Greek, a language where the orthographic and phonological overlap between present and past tense stems is the same for both regular and irregular verbs. The experiment described here is a follow-up study of previous visual lexical decision experiments (Tsapkini, Kehayia, & Harema, 2002) that also addressed the regular-irregular distinction in Greek. In the present experiment, we investigated the effect of input modality in lexical processing and compared different types of regular and irregular verbs. In contrast to our previous intra-modal (visual-visual) priming experiments, in this cross-modal (auditory-visual) priming study, we found that regular verbs with an orthographically salient morphemic aspectual marker elicited the same facilitation as those without an orthographically salient marker. However, irregular verbs did not exhibit a different priming pattern with respect to modality. We interpret these results in the framework of a two-level lexical processing approach with modality-specific access representations at a surface level and modality-independent morphemic representations at a deeper level.     

论道德的本真形态与派生形态

道德的本真形态是“天理”和“良心”,即普遍的、至高无上的实践法则及其在人心中的体现。道德要通过人的理论和实践体现出来,就需要实现道德的学理化和规范化,从而形成道德理论与社会规范两种道德的派生形态。     

The P600 as an indicator of syntactic ambiguity

In a study using event-related brain potentials, we show that the current characterization of the P600 component as an indicator of revision processes (reanalysis and repair) in sentence comprehension must be extended to include the recognition of syntactic ambiguity. By comparing the processing of ambiguous and unambiguous sentence constituents in German, we show that the P600 is elicited when our language processing system has syntactic alternatives at a certain item given in the input string. That the P600 is sensitive to syntactic ambiguity adds crucial evidence to current debates in psycholinguistic modelling, as the results clearly favour parallel models of syntactic processing which assume that ambiguity is recognized and costly.     

LOCKE'S LOGIC OF IDEAS IN CONTEXT: CONTENT AND STRUCTURE

Contrary to the claims of recent commentators, I argue that Boethius holds a modified version of the Ammonian three-fold universal (transcendent, immanent, and conceptual). He probably identifies transcendent universals as divine ideas, and accepts too forms immanent in corporeal particulars, most likely construing these along the Aphrodisian lines that he hints at in a well-known passage from his second commentary on Porphyry's Isagoge. Boethius never states the theory of the three-fold form outright, but I attempt to show that this theory nevertheless underlies and gives structure to what Boethius has to say on the topic.     

Sequential or parallel decomposed processing of two-digit numbers? Evidence from eye-tracking

While reaction time data have shown that decomposed processing of two-digit numbers occurs, there is little evidence about how decomposed processing functions. Poltrock and Schwartz (1984) argued that multi-digit numbers are compared in a sequential digit-by-digit fashion starting at the leftmost digit pair. In contrast, Nuerk and Willmes (2005) favoured parallel processing of the digits constituting a number. These models (i.e., sequential decomposition, parallel decomposition) make different predictions regarding the fixation pattern in a two-digit number magnitude comparison task and can therefore be differentiated by eye fixation data. We tested these models by evaluating participants' eye fixation behaviour while selecting the larger of two numbers. The stimulus set consisted of within-decade comparisons (e.g., 53_57) and between-decade comparisons (e.g., 42_57). The between-decade comparisons were further divided into compatible and incompatible trials (cf. Nuerk, Weger, & Willmes, 2001) and trials with different decade and unit distances. The observed fixation pattern implies that the comparison of two-digit numbers is not executed by sequentially comparing decade and unit digits as proposed by Poltrock and Schwartz (1984) but rather in a decomposed but parallel fashion. Moreover, the present fixation data provide first evidence that digit processing in multi-digit numbers is not a pure bottom-up effect, but is also influenced by top-down factors. Finally, implications for multi-digit number processing beyond the range of two-digit numbers are discussed.     

Serial and parallel processing in reading: Investigating the effects of parafoveal orthographic information on nonisolated word recognition

We present a novel lexical decision task and three boundary paradigm eye-tracking experiments that clarify the picture of parallel processing in word recognition in context. First, we show that lexical decision is facilitated by associated letter information to the left and right of the word, with no apparent hemispheric specificity. Second, we show that parafoveal preview of a repeat of word n at word n + 1 facilitates reading of word n relative to a control condition with an unrelated word at word n + 1. Third, using a version of the boundary paradigm that allowed for a regressive eye movement, we show no parafoveal “postview” effect on reading word n of repeating word n at word n – 1. Fourth, we repeat the second experiment but compare the effects of parafoveal previews consisting of a repeated word n with a transposed central bigram (e.g., caot for coat) and a substituted central bigram (e.g., ceit for coat), showing the latter to have a deleterious effect on processing word n, thereby demonstrating that the parafoveal preview effect is at least orthographic and not purely visual.     

Can hearing puter activate pupil? Phonological competition and the processing of reduced spoken words in spontaneous conversations

In listeners' daily communicative exchanges, they most often hear casual speech, in which words are often produced with fewer segments, rather than the careful speech used in most psycholinguistic experiments. Three experiments examined phonological competition during the recognition of reduced forms such as [pjut?r] for computer using a target-absent variant of the visual world paradigm. Listeners' eye movements were tracked upon hearing canonical and reduced forms as they looked at displays of four printed words. One of the words was phonologically similar to the canonical pronunciation of the target word, one word was similar to the reduced pronunciation, and two words served as unrelated distractors. When spoken targets were presented in isolation (Experiment 1) and in sentential contexts (Experiment 2), competition was modulated as a function of the target word form. When reduced targets were presented in sentential contexts, listeners were probabilistically more likely to first fixate reduced-form competitors before shifting their eye gaze to canonical-form competitors. Experiment 3, in which the original /p/ from [pjut?r] was replaced with a “real” onset /p/, showed an effect of cross-splicing in the late time window. We conjecture that these results fit best with the notion that speech reductions initially activate competitors that are similar to the phonological surface form of the reduction, but that listeners nevertheless can exploit fine phonetic detail to reconstruct strongly reduced forms to their canonical counterparts.
