The Many Senses of Imagination and the Manifestation of Fiction: A View from Husserl’s Phenomenology of Phantasy

The systematic importance of the eidetic account of phantasy for Husserlian phenomenology in general is undisputed, but whether this account can be relevant for Aesthetics has often been put into question. In this paper I argue that Husserl’s rich phenomenology of phantasy, and in particular his account of perceptual phantasy, can nevertheless significantly enhance our understanding of how we recognize and imaginatively participate in artistic fictions. Moreover, I show how Husserl’s peculiar formulation of a non-intuitive phantasy at stake in artistic representation anticipates some uses of the imagination in Aesthetics suggested by Ernst Gombrich and Kendall Walton.     

Landmark Frames of Reference in Interactive Route Description Tasks

The current study investigated the use of frames of reference in an asymmetrical spatial dialogue task. Participants navigated through a real environment by following instructions provided by other participants guiding them over the phone. The dialogues were transcribed and analysed to locate the introduction of landmarks. We examined which frames of reference were used to introduce these landmarks and how far their use was determined by each participant's role within the dyads (i.e. guide vs. guided person). Results revealed that both partners contributed to the dialogue by introducing landmarks. However, the guides introduced more landmarks than the guided persons and were also more likely to use perspective taking when doing so. These results are discussed in the light of perspective taking and collaboration in dialogue. Copyright © 2013 John Wiley & Sons, Ltd.     

How Should We Assess the Fit of Rasch-Type Models? Approximating the Power of Goodness-of-Fit Statistics in Categorical Data Analysis

We investigate the performance of three statistics, R ₁, R ₂ (Glas in Psychometrika 53:525–546, 1988), and M ₂ (Maydeu-Olivares & Joe in J. Am. Stat. Assoc. 100:1009–1020, 2005, Psychometrika 71:713–732, 2006) to assess the overall fit of a one-parameter logistic model (1PL) estimated by (marginal) maximum likelihood (ML). R ₁ and R ₂ were specifically designed to target specific assumptions of Rasch models, whereas M ₂ is a general purpose test statistic. We report asymptotic power rates under some interesting violations of model assumptions (different item discrimination, presence of guessing, and multidimensionality) as well as empirical rejection rates for correctly specified models and some misspecified models. All three statistics were found to be more powerful than Pearson’s X ² against two- and three-parameter logistic alternatives (2PL and 3PL), and against multidimensional 1PL models. The results suggest that there is no clear advantage in using goodness-of-fit statistics specifically designed for Rasch-type models to test these models when marginal ML estimation is used.     

Plasticity of GaAs(011) at room temperature under concentrated load

Indentations have been made on a (011) surface of GaAs single crystal at room temperature. The loading-unloading curves were compared with those obtained under the same experimental conditions on (001) surfaces. The indents formed were observed by transmission electron microscopy in plan view as well as in cross-sectional view in samples prepared by the focused-ion-beam technique. The gliding systems could be identified, providing a better understanding of the plastic flow under the indenter. The arrangements of dislocations generated by the indenter have been analysed and compared with results previously reported by Ning et al.     

Ab initio investigation of electron-phonon interaction in LaSn3 and CaSn3

ABSTRACT

We present results for the structural, electronic, vibrational, and electron-phonon coupling properties of LaSn₃ and CaSn₃ adopting the simple cubic AuCu₃-type structure obtained using the the generalised gradient approximation of the density functional theory and plane wave ab initio pseudopotential method. Our electronic results show that both materials display metallic character with several bands, which have mainly Sn 5p character, crossing the Fermi level. The calculated phonon spectrum of LaSn₃ accords very well with reported experimental measurements. The weights of the peaks in the Eliashberg spectral function of both compounds are enhanced with the use of experimental lattice constant in our electron-phonon calculation, increasing the value of average electron phonon coupling parameter from 0.876 to 0.937 for LaSn₃ (by 7%) and from 0.642 to 0.725 for CaSn₃ (by 13%). The use of experimental lattice constant also improves the agreement between theoretical and experimental values of the superconducting temperature for both compounds.     

Estimating One's Own and Others' Multiple Intelligence: A Cross-Cultural Study from Guinea Bissau and Portugal

This study examined the estimations of multiple intelligences for self, partner and parents. One hundred and fifty two students (males = 81, females = 68, and 3 have not indicated their sex; mean age = 24.02, SD = 3.08) from Guinea Bissau estimated their own, their partners', and their parents' IQ scores on each of Gardner's ten multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body-kinesthetic, interpersonal, intrapersonal, existential, spiritual and naturalistic. In contrast to previous results (A. Furnham, 2001) sex differences in self-estimates did not occur in this Guinean sample. Participants rated overall intelligence of their father higher than that of their mother. An existing data set on estimates of intelligence in a Portuguese sample was used for a cross-cultural comparison between Portuguese and Guinean participants. There were consistent and clear culture differences. Guinean gave higher self, partner and family ratings than Portuguese. Results are discussed in terms of the growing literature in the self-estimates of intelligence, as well as limitations of that approach.     

Distorted Reflections: Media Exposure and Latino Adolescents' Conceptions of Self

Because Latinos are underrepresented and often negatively stereotyped in the media, concern is frequently expressed that repeated exposure to these portrayals may reflect poorly on Latino adolescents' self-esteem. To test this issue empirically, we conducted 2 studies examining associations between multiple dimensions of self-esteem and several forms of media use. Testing 40 Latino high school students in Study 1, we found that more frequent and more active TV viewing was associated with lower social and appearance self-esteem. Many of these general patterns were replicated in Study 2 with 115 college students and with several demographic controls. Additional analyses of possible moderators revealed more consistent negative correlations among women and among participants with a stronger Latino ethnic identity. Together, these findings provide powerful evidence of a potential link between media use and the self-conceptions of Latino youth.     

伤害回避的脑机制及其生物基础

伤害回避是指个体对厌恶刺激信号做出强烈的反应,并学会被动地回避惩罚的一种倾向,这一倾向使得个体反复思考未来的结局,并谨慎小心地对待不确定情景中的事件,进而更有可能诱发情感障碍。伤害回避涉及的神经网络包括三个子网络,即额顶叶-前扣带皮层的连接、皮层-杏仁核的连接和白质通道的结构性连接,这三个子网络分别与羞怯感-易疲劳性、预期担心以及不确定环境中的害怕情绪有关。而其生物基础则包括单一基因多态性和基因多态间的交互作用。今后的研究应该集中在深化伤害回避神经网络与生物基础间的联合机制、研究三种及以上基因多态间的交互作用、考察其他因素对基因效应的调节作用、注重伤害回避四种亚型相关神经网络之间的连接、探讨5-HT4等其他几种5-羟色胺受体多态性与伤害回避的关系以及分析伤害回避内部机制在抗抑郁治疗中的作用等方面。     

Tracking the first two seconds: three stages of visual information processing?

We compared visual priming and comparison tasks to assess information processing of a stimulus during the first 2 s after its onset. In both tasks, a 13-ms prime was followed at varying SOAs by a 40-ms probe. In the priming task, observers identified the probe as rapidly and accurately as possible; in the comparison task, observers determined as rapidly and accurately as possible whether or not the probe and prime were identical. Priming effects attained a maximum at an SOA of 133 ms and then declined monotonically to zero by 700 ms, indicating reliance on relatively brief visuosensory (iconic) memory. In contrast, the comparison effects yielded a multiphasic function, showing a maximum at 0 ms followed by a minimum at 133 ms, followed in turn by a maximum at 240 ms and another minimum at 720 ms, and finally a third maximum at 1,200 ms before declining thereafter. The results indicate three stages of prime processing that we take to correspond to iconic visible persistence, iconic informational persistence, and visual working memory, with the first two used in the priming task and all three in the comparison task. These stages are related to stages presumed to underlie stimulus processing in other tasks, such as those giving rise to the attentional blink.
