Eye movements of monkey observers viewing vocalizing conspecifics

Primates, including humans, communicate using facial expressions, vocalizations and often a combination of the two modalities. For humans, such bimodal integration is best exemplified by speech-reading - humans readily use facial cues to enhance speech comprehension, particularly in noisy environments. Studies of the eye movement patterns of human speech-readers have revealed, unexpectedly, that they predominantly fixate on the eye region of the face as opposed to the mouth. Here, we tested the evolutionary basis for such a behavioral strategy by examining the eye movements of rhesus monkeys observers as they viewed vocalizing conspecifics. Under a variety of listening conditions, we found that rhesus monkeys predominantly focused on the eye region versus the mouth and that fixations on the mouth were tightly correlated with the onset of mouth movements. These eye movement patterns of rhesus monkeys are strikingly similar to those reported for humans observing the visual components of speech. The data therefore suggest that the sensorimotor strategies underlying bimodal speech perception may have a homologous counterpart in a closely related primate ancestor.     

A “RESOLUTE” LATER WITTGENSTEIN?

Abstract: “Resolute readings” initially started life as a radical new approach to Wittgenstein's early philosophy, but are now starting to take root as a way of interpreting the later writings as well—a trend exemplified by Stephen Mulhall's Wittgenstein's Private Language (2007) as well as by Phil Hutchinson's “What's the Point of Elucidation?” (2007) and Rom Harré's “Grammatical Therapy and the Third Wittgenstein” (2008). The present article shows that there are neither good philosophical nor compelling exegetical grounds for accepting a resolute reading of the later Wittgenstein's work. It is possible to make sense of Wittgenstein's philosophical method without either ascribing to him an incoherent conception of “substantial nonsense” or espousing the resolute readers' preferred option of nonsense austerity. If the interpretation here is correct, it allows us to recognize Wittgenstein's radical break with the philosophical tradition without having to characterize his achievements in purely therapeutic fashion.     

School profiles of at-risk student concentration: Differential growth in oral reading fluency

The present study provides a data-driven approach to identifying groups of schools based on the concentration of at-risk students the school serves. The percentage of English language learners, minority students, and students eligible for free or reduced priced lunch were used as indicators in a latent profile analysis of 569 schools. The goal of the present study was to determine whether school-level average student reading performance varied as a function of the groups identified in the latent profile analysis. To do so, groups extracted by the latent profile analysis were used as school-level predictors of growth in oral reading fluency, which was modeled at the within-student level of a three-level hierarchical growth curve model. Oral reading fluency was measured at four points during the year in a large cross-sectional sample of first-, second-, and third-grade students. Results indicated that schools were able to be classified into four distinct groups based on their concentrations and types of at-risk students. Further, in all three grades, there were significant differences between the four identified groups observed in average reading fluency scores at the beginning of the year, the end of the year, and growth during the year indicating that groups based on school-concentration of at-risk students were significantly related to average student achievement in reading ability.     

Flowing Within the Text: A Discussion on He Lin’s Explanation of Zhu Xi’s Method of Intuition

The author examines He Lin’s interpretation of Zhu Xi’s method of intuition from a phenomenological-hermeneutical perspective and by exposing Zhu’s philosophical presuppositions. In contrast with Lu Xiangshan’s intuitive method, Zhu Xi’s method of reading classics advocates “emptying your heart and flowing with the text” and, in this spirit, explains the celebrated “exhaustive investigation on the principles of things (ge wu qiong li).” “Text,” according to Zhu, is therefore not an object in ordinary sense but a “contextual region” or “sensible pattern” that, when merged with the reader, generates meanings. Furthermore, by discussing the related doctrines of Lao Zi, Zhuang Zi, Hua-Yan Buddhism, Zhou Dunyi, and Zhu Xi’s own “One principle with many manifestations (li yi fen shu),” the author identifies the philosophical preconditions of Zhu’s method. Based on this analysis, the author goes on to illustrate Zhu’s understanding of “observing potential yet unapparent pleasure, anger, sorrow and happiness” and “maintaining a serious attitude (zhu jing).”

Descartes on the distinction between primary and secondary qualities

ABSTRACT

Descartes did not use the terms ‘primary’ and ‘secondary’ qualities, but a similar distinction emerges from his texts: certain qualities of objects (such as size and shape) are intrinsic properties of matter, whereas others (like colours and smells) are products of the interaction with a perceiver. A common interpretation states that the division between primary and secondary qualities is explained by the way in which we are acquainted with them: an idea of a primary quality is similar to its physical causes, and it is clearly and distinctly perceived by the intellect. An idea of a secondary quality is dissimilar to its physical causes and it is obscurely and confusedly perceived by the senses. This view receives the name of ‘bifurcation reading’ (Simmons, A. ‘Descartes on the Cognitive Structure of Sensory Experience’. Philosophy and Phenomenological Research, LXVII, no. 3 (November 2003)). While it integrates well some textual occurrences, it creates a problematic fragmentation within single acts of perception. This paper contends that this reading is incorrect. It presents several arguments for the claim that the distinction of qualities is due to the different ways in which our ideas of them misrepresent their physical causes. Then, Descartes’ dissimilarity thesis between physical objects and our ideas of them remains a structural feature of his theory of sensory perception and not a local phenomenon affecting only ideas of secondary qualities.     

Strategic grouping in the spatial span memory task

Spatial short-term memory performance was examined in relation to participants’ strategies. A total of 20 adult participants viewed and reproduced sequences of locations that varied in length (five, six, seven, or eight locations) and spatial separability (a manipulation of the configurations). In trial-by-trial self-reports, participants described five types of strategies. Chunking the spatial sequences into groups of three or four locations was the sole strategy associated with increased accuracy. Participants demonstrated considerable variability in the strategies that they selected, suggesting that cognitive resources are allocated to strategy selection, execution, and monitoring in the spatial span task. Spatially separable sequences were more accurately recalled than nonseparable sequences, independent of strategic grouping, suggesting two levels of grouping in the spatial span task.     

A brief introduction to the work of Jean Laplanche

The author proposes an introduction to the work of Jean Laplanche, a well‐known figure of psychoanalysis who recently passed away. He foregrounds what he views as the three main axes of Laplanche's work: firstly, a critical reading method applied to Freud's texts; secondly, a model of psychic functioning based on translation; and, thirdly, a theory of general seduction. Far from being an abstract superstructure, the theory of general seduction is firmly rooted in the analytic situation, as the provocation of transference by the analyst best illustrates. The analytic situation indeed consists in a revival and a reopening of the ‘fundamental anthropological situation’ which, according to Laplanche, is the lot of every human baby born in a world where he or she is necessarily exposed to the enigmatic and ‘compromised’ messages of the adult other. Thanks to the process of analytic de‐translation, the analysand is therefore granted an opportunity to carry out new translations of the other's enigma – translations or symbolizations that might be more inclusive and less rigid than the pre‐existing ones. Incidentally, such a model brings together the purely psychoanalytic and the psychotherapeutic aspects of the treatment.
