Comparison of ability tests administered online and in the laboratory

As the Internet, the global medium of the future, expands exponentially, it has become increasingly relevant to scientific research. So far, there is but little evidence that online testing is suitable for collecting ability-test data. The present article aims to shed light on some aspects of the issue by comparing the performance in a computer-administered ability test of one lab sample and two online samples using a quasi-experimental design. Mean score differences appeared, but can be explained by differences in age and education, and were not due to the test setting (online vs. laboratory). Also, there were no structural differences between the achievement scores of both samples. Some limitations on generalizability are discussed.     

年龄和性别对气味和词汇的语义识别的不同影响

本研究采用基于人口学特征的大规模取样, 通过线索气味识别测验和词汇测验考察了年龄和性别因素对嗅觉功能和语义知识的影响。1497位健康的成人(35岁~95岁)参与了气味识别和词汇熟练性测验。结果表明年龄对两项测验的成绩都有显著的负面影响, 尽管嗅觉测验的年龄效应更大。女性比男性识别出更多的气味且这种效应与年龄无关, 这进一步证实了先前的观察。本文详细讨论了这些发现的意义。     

A (R)evaluation of Nietzsche’s Anti-democratic Pedagogy: The Overman,Perspectivism, and Self-overcoming

In this paper, I argue that Friedrich Nietzsche’s concept of self-overcoming has been largely misinterpreted in the philosophy of education journals. The misinterpretation partially stems from a misconstruction of Nietzsche’s perspectivism, and leads to a conception of self-overcoming that is inconsistent with Nietzsche’s educational ideals. To show this, I examine some of the prominent features of the so-called “debate” of the 1980s surrounding Nietzsche’s conception of self-overcoming. I then offer an alternative conception that is more consistent with Nietzsche’s thought, and provides a more nuanced understanding of Nietzsche’s “anti-democratic” pedagogy. Ultimately, I argue that while Nietzsche’s educational philosophy is not egalitarian, it can be effectively utilized in “democratic” classrooms, assuming his concept of self-overcoming is properly construed.

Inspirational Patterns for Embodied Interaction

The concern of this work is how knowledge based on design experience can be developed, disseminated, articulated, and acquired. We propose the notion of inspirational patterns, or i-patterns, which refers to abstractions of core ideas and essential elements from a class of coherent examples, pointing to promising regions in the design space. Most current work on patterns concentrates on proven solutions to recurring problems; i-patterns, on the other hand, are oriented toward the innovative and inspirational. The design domain of interest to us is interaction design, which can be roughly defined as design with digital materials. More specifically, we focus on the intersection of tangible interfaces and social computing that is called embodied interaction. The paper presents nine i-patterns for embodied interaction, including “Virtual information is tied to positions in the material world” and “Heterogeneous virtual information fuses into a few sensory parameters.” Published in Proc.

Why some groups just feel better: the regulatory fit of group power

The current research applied the regulatory fit hypothesis (E. T. Higgins, 2000) to the evaluation of groups, suggesting that individuals' group appraisal depends on how well the groups fit their regulatory needs. Specifically, it was predicted that higher power groups would fit and be more valued by those individuals with a promotion focus because these groups provide a better opportunity to sustain nurturance and achievement needs. Alternatively, lower power groups were predicted to fit and be more valued by those individuals with a prevention focus because these groups necessitate (and thus sustain) a focus on safety and security. Five studies found support for these predictions by both assessing and manipulating regulatory focus and group power and by using explicit and implicit measures of group attraction. Moreover, these regulatory fit effects occurred specifically for group power and not for general differences in group status.     

Localisation of auditory targets during optokinetic nystagmus

Previous studies have shown that the perceived location of visual stimuli briefly flashed during smooth pursuit, saccades, or optokinetic nystagmus (OKN) is not veridical. We investigated whether these mislocalisations can also be observed for brief auditory stimuli presented during OKN. Experiments were carried out in a lightproof sound-attenuated chamber. Participants performed eye movements elicited by visual stimuli. An auditory target (white noise) was presented for 5 ms. Our data clearly indicate that auditory targets are mislocalised during reflexive eye movements. OKN induces a shift of perceived location in the direction of the slow eye movement and is modulated in the temporal vicinity of the fast phase. The mislocalisation is stronger for look- as compared to stare-nystagmus. The size and temporal pattern of the observed mislocalisation are different from that found for visual targets. This suggests that different neural mechanisms are at play to integrate oculomotor signals and information on the spatial location of visual as well as auditory stimuli.     

Learning to Reach by Constraining the Movement Search Space

Trial‐and‐error learning strategies play a central role in sensorimotor development during early infancy. However, learning to reach by trial‐and‐error normally requires a slow and laborious search through the space of possible movements. We propose a computational model of reaching based on the notion that early sensorimotor control is driven by the generation of exploratory movements, followed by the selection and maintenance of adaptive movement patterns. We find that, instead of exhaustively exploring the full search space of movement patterns, the model exploits several emergent constraints that limit the initial size of the movement search space. These constraints exploit both mechanical and kinematic properties of the reaching task. We relate these results to the development of reaching during infancy, and discuss recent findings that have identified similar constraints in young infants.     

Recruiting Through Job Advertisements: The Effects of Cognitive Elaboration on Decision Making

We applied a model of persuasion – the elaboration likelihood model – to investigate whether individuals' decisions about responding to job advertisements are affected by how deeply they process recruitment messages (i.e., elaboration likelihood, EL). We manipulated individuals' (N=112) motivation and ability to carefully process job advertisements (ads). As hypothesized, individuals in the lower (vs. higher) EL conditions chose more ads containing cues unrelated to the job (e.g., bolded font), and fewer ads containing higher quality arguments. Participants also reported that they “skimmed” and carefully read job ads in the past, providing evidence for variability in EL among job seekers. We discuss the implications of the findings for recruiters who wish to increase the size of their applicant pool.
