Birth of an Abstraction: A Dynamical Systems Account of the Discovery of an Elsewhere Principle in a Category Learning Task

Human participants and recurrent (“connectionist”) neural networks were both trained on a categorization system abstractly similar to natural language systems involving irregular (“strong”) classes and a default class. Both the humans and the networks exhibited staged learning and a generalization pattern reminiscent of the Elsewhere Condition (Kiparsky, 1973). Previous connectionist accounts of related phenomena have often been vague about the nature of the networks’ encoding systems. We analyzed our network using dynamical systems theory, revealing topological and geometric properties that can be directly compared with the mechanisms of non‐connectionist, rule‐based accounts. The results reveal that the networks “contain” structures related to mechanisms posited by rule‐based models, partly vindicating the insights of these models. On the other hand, they support the one mechanism (OM), as opposed to the more than one mechanism (MOM), view of symbolic abstraction by showing how the appearance of MOM behavior can arise emergently from one underlying set of principles. The key new contribution of this study is to show that dynamical systems theory can allow us to explicitly characterize the relationship between the two perspectives in implemented models.     

Aligning inside and outside perspectives of the self: A cross‐cultural difference in self‐perception

Past research shows that European Americans tend to take a first‐person perspective to understand the self and are unlikely to align the inside look with the outside gaze, whereas Asians tend to take a third‐person perspective and are likely to shift their inside look in the direction of the outsize gaze. In three experiments, we compared Asians and European Americans' self‐perceptions when the presence of their parents in the background of self‐perception was primed or otherwise. Without the priming, both European Americans and Asians viewed themselves more positively from their own perspective than from their parents' perspective. With the priming, only Asians lowered the positivity of their self‐perceptions to match the perceived positivity of the self in the parents' perspective. These results suggest that Asians do not have a static, passive tendency to assimilate their self‐views into the perceived external assessments of the self. Rather, their self‐views are fluid and flexible.     

The influence of number line estimation precision and numeracy on risky financial decision making

This study examined whether different aspects of mathematical proficiency influence one's ability to make adaptive financial decisions. “Numeracy” refers to the ability to process numerical and probabilistic information and is commonly reported as an important factor which contributes to financial decision‐making ability. The precision of mental number representation (MNR), measured with the number line estimation (NLE) task has been reported to be another critical factor. This study aimed to examine the contribution of these mathematical proficiencies while controlling for the influence of fluid intelligence, math anxiety and personality factors. In our decision‐making task, participants chose between two options offering probabilistic monetary gain or loss. Sensitivity to expected value was measured as an index for the ability to discriminate between optimal versus suboptimal options. Partial correlation and hierarchical regression analyses revealed that NLE precision better explained EV sensitivity compared to numeracy, after controlling for all covariates. These results suggest that individuals with more precise MNR are capable of making more rational financial decisions. We also propose that the measurement of “numeracy,” which is commonly used interchangeably with general mathematical proficiency, should include more diverse aspects of mathematical cognition including basic understanding of number magnitude.

Out-of-bag Prediction Error: A Cross Validation Index for Generalized Structured Component Analysis

Cross validation is a useful way of comparing predictive generalizability of theoretically plausible a priori models in structural equation modeling (SEM). A number of overall or local cross validation indices have been proposed for existing factor-based and component-based approaches to SEM, including covariance structure analysis and partial least squares path modeling. However, there is no such cross validation index available for generalized structured component analysis (GSCA) which is another component-based approach. We thus propose a cross validation index for GSCA, called Out-of-bag Prediction Error (OPE), which estimates the expected prediction error of a model over replications of so-called in-bag and out-of-bag samples constructed through the implementation of the bootstrap method. The calculation of this index is well-suited to the estimation procedure of GSCA, which uses the bootstrap method to obtain the standard errors or confidence intervals of parameter estimates. We empirically evaluate the performance of the proposed index through the analyses of both simulated and real data.     

Item response theory analyses of the Delis-Kaplan Executive Function System card sorting subtest

In the current study, we examined the dimensionality of the 16-item Card Sorting subtest of the Delis-Kaplan Executive Functioning System assessment in a sample of 264 native English-speaking children between the ages of 9 and 15 years. We also tested for measurement invariance for these items across age and gender groups using item response theory (IRT). Results of the exploratory factor analysis indicated that a two-factor model that distinguished between verbal and perceptual items provided the best fit to the data. Although the items demonstrated measurement invariance across age groups, measurement invariance was violated for gender groups, with two items demonstrating differential item functioning for males and females. Multigroup analysis using all 16 items indicated that the items were more effective for individuals whose IRT scale scores were relatively high. A single-group explanatory IRT model using 14 non-differential item functioning items showed that for perceptual ability, females scored higher than males and that scores increased with age for both males and females; for verbal ability, the observed increase in scores across age differed for males and females. The implications of these findings are discussed.     

Self-Control and Risky Lifestyles in Context: Cross-Level Integration between Opportunity and Collective Efficacy in the Study of Peer Victimization among South Korean Youth

The study applies individual trait and opportunity perspectives at the individual-level factors associated with peer victimization among South Korean youth. The theoretical analysis integrates individual-level perspectives with community-level perspective. Data are derived from the Korean Youth Panel Survey, which provided information for a sample of 2844 adolescents, aged 11. Findings revealed significant effects of low self-control and risky lifestyles (delinquent peer associations and juvenile delinquency) on peer victimization. The results lend support for the application of self-control theory as well as lifestyles and routine activities theory to understand peer victimization of adolescents in South Korea. However, there was no independent effect of neighborhood collective efficacy on peer victimization, nor did neighborhood collective efficacy attenuate or condition the individual-level effects on peer victimization.     

Two-Headed Coins or Kandinskys: White Racial Identification

Racial identity means different things to members of different racial and ethnic groups in the United States. However, while the study of race and politics is often the study of White racial attitudes ( Dawson & Cohen, 2003 ), research on racial identity almost always refers to non-White identity. This article addresses this hole in the literature by examining the extent and effects of White identity. We compare White identification and Black identification using National Election Studies data (1972–2000) and examine the relationships between racial identity and racial and political attitudes. This study adds a missing case to the study of racial identity, tests how well the theories about the concept travel across cases, and highlights the need for more frequent studies of the racial identity of all groups.     

From Buddha's speech to Buddha's essence: philosophical discussions of Buddha‐vacana in India and China1

This is a comparative study of the discourses on the nature of sacred language found in Indian Abhidharma texts and those written by 7th century Chinese Buddhist scholars who, unlike the Indian Buddhists, questioned ‘the essence of the Buddha’s teaching'. This issue labeled fo‐chiao t'i lun, the theory of ‘the essence of the Buddha’s teaching', was one of the topics on which Chinese Yogācāra scholars have shown a keen interest and served as the inspiration for extensive intellectual dialogues in their texts. It is in Hsüan‐tsang's massive and organized translation works, begun in 648, that various previous translations of the term buddhavacana from Indian Abhidharma texts were given the unified translation of fo‐chiao. (Fo‐chiao literally means “the Buddha's teachings,” and is the term used in the modern period for “Buddhism.”) By combining fo‐chiao with the term t'i, meaning ‘essence’ or ‘substance’ throughout his translations, Hsüan‐tsang attempted to define ‘the essence of the Buddha’s teaching'. In Indian Abhidharma texts, the nature of the Buddha's word was either ‘sound’ (?abdha), the oral component of speech, or ‘name’ (nāma), the component of language that conveys meaning, or some combination of the two. From the time of Hsüan‐tsang's translation, however, discourse on the nature of sacred language was no longer relegated to the category of language or of epistemological investigation, but became grounded in the Chinese discussion investigating the ‘essence’ or ‘substance’ of the Buddha's teaching, and even of ‘Buddhism’ itself. As such, it sought to transcend the distinction between language and meaning. This gradual but explicit process of inquiry into the nature of ‘the Buddha’s word' was a necessary antecedent to the transition to a ‘Chinese’ Buddhism.
