Effectiveness Evaluation of Search and Target Acquisition Training Prototype Using Performance Metrics With Eye-Tracking Data

Despite the increased use of sensor technologies, including unmanned vehicles, the vast majority of improvised explosive device (IED) detections are made by human vision. Thus, TRAC-Monterey developed a simulation-based training prototype called the perceptual learning trainer (PLT). Fourteen novice and 5 expert IED detectors participated in human-in-the-loop experiments in which all participants were trained using the PLT tool while their eye-movement and IED detection performance were tracked in real-time. A series of 100 IED images with various degrees of difficulty was used for the training session. Pre- and posttraining assessments were conducted. Both speed and accuracy improved after just 1 session of the PLT training: RT decreased by 3.7 s for novices (p < .001) and 3.4 s for experts (p = .031), and detection probability increased by 5.9% for novices (p = .001). The PLT tool improved IED detection performance more in novice IED detectors than in experts. Novices and experts showed different visual scan patterns.     

Two faces,two languages: An fMRI study of bilingual picture naming

This fMRI study explores how nonlinguistic cues modulate lexical activation in the bilingual brain. We examined the influence of face race on bilingual language production in a picture-naming paradigm. Chinese–English bilinguals were presented with pictures of objects and images of faces (Asian or Caucasian). Participants named the picture in their first or second language (Chinese or English) in separate blocks. Face race and naming language were either congruent (e.g., naming in Chinese when seeing an Asian face) or incongruent (e.g., naming in English when seeing an Asian face). Our results revealed that face cues facilitate naming when the socio-cultural identity of the face is congruent with the naming language. The congruence effects are reflected as effective integration of lexical and facial cues in key brain regions including IFG, MFG, ACC, and caudate. Implications of the findings in light of theories of language processing and cultural priming are discussed.     

Beyond the information given: Infants’ transfer of actions learned through imitation

Five experiments were conducted to investigate infants’ ability to transfer actions learned via imitation to new objects and to examine what components of the original context are critical to such transfer. Infants of 15 months observed an experimenter perform an action with one or two toys and then were offered a novel toy that was not demonstrated for them. In all experiments, infants performed target actions with the novel toy more frequently than infants who were offered the same toy but had seen no prior demonstrations. Infants exhibited transfer even when the specific part to be manipulated looked different across the toys, even when they had not performed the actions with the demonstration toys themselves, even when the actions produced no effects on the demonstrations, and even when the actions were demonstrated with only a single exemplar toy. Transfer was especially robust when infants not only observed but also practiced the target actions on the demonstration trials. Learning action affordances (“means”) seems to be a central aspect of human imitation, and the propensity to apply these learned action affordances in new object contexts may be an important basis for technological innovation and invention.     

Emotional facilitation effect in the picture–word interference task: An ERP study

In this paper, we aimed to verify the emotional facilitation effect in the picture–word interference task using event-related potentials. Twenty-one healthy subjects were asked to categorize the emotional valences of pictures accompanied by emotionally congruent, either centrally or laterally positioned Chinese words. For both the foveal and lateral word presentations, the reaction times were faster compared to the picture-only presentation. Compared to the picture-only presentation, P200 amplitude increased under the foveal word presentation condition and decreased under the lateral word presentation condition, indicating that more attentional resources were required when an accompanying word was in the center of a picture than when the word was in the lateral position. Latency of P300 was shorter in response to picture–word stimuli irrespective of word position, indicating that an emotionally congruent word facilitated the emotional processing of the target picture, which verified the emotional facilitation effect and was consistent with the results in psychology. The late positive component was more positive when the picture–word stimuli were more positive, which reflected the feature of positivity offset. The findings suggest that the time window for an emotional facilitation effect may be limited to processing aspects associated with P300 (i.e., affective evaluation).     

Feature selection for inductive generalization

Judging similarities among objects, events, and experiences is one of the most basic cognitive abilities, allowing us to make predictions and generalizations. The main assumption in similarity judgment is that people selectively attend to salient features of stimuli and judge their similarities on the basis of the common and distinct features of the stimuli. However, it is unclear how people select features from stimuli and how they weigh features. Here, we present a computational method that helps address these questions. Our procedure combines image-processing techniques with a machine-learning algorithm and assesses feature weights that can account for both similarity and categorization judgment data. Our analysis suggests that a small number of local features are particularly important to explain our behavioral data.     

理论的建构与验证:来自社会认同研究的经验(英文)

科学研究的核心在于理论的建构与验证。基于社会认同和群际关系研究的经验,本文提出了建构与验证心理学理论的四步方法:1)选择现象——观察我们身边及周围世界所发生的事件;2)寻找关键共性——厘定不同事件间的共同成份;3)抽象化(理论化)——提取关键共性中潜存的基本心理过程,并将其与已有的或者最新的理论相联系;4)验证假设——利用实验反复地验证理论。以上四个步骤引导着研究者针对现实生活中的社会事件展开科学研究。文章将以等级身份、身份霸权和桥梁身份等研究为例阐明上述方法,同时也提出在社会和人格心理学领域开展系统性研究的准则。     

For whom is parting with possessions more painful? Cultural differences in the endowment effect

The endowment effect--the tendency for owners (potential sellers) to value objects more than potential buyers do--is among the most widely studied judgment and decision-making phenomena. However, the current research is the first to explore whether the effect varies across cultures. Given previously demonstrated cultural differences in self-construals and self-enhancement, we predicted a smaller endowment effect for East Asians compared with Westerners. Two studies involving buyers and sellers of a coffee mug (Study 1a) and a box of chocolates (Study 1b) supported this prediction. Study 2 conceptually replicated this cultural difference by experimentally manipulating independent and interdependent self-construals. Finally, Study 3 provided evidence for an underlying self-enhancement mechanism: Cultural differences emerged when self-object associations were made salient, but disappeared when self-object associations were minimized. Thus, the endowment effect may be influenced by the degree to which independence and self-enhancement (vs. interdependence and self-criticism) are culturally valued or normative.     

儒家德刑观论析

在道德与法律、德治与刑罚的关系问题上,儒家从其仁爱的思想原则出发,主张为政以德,强调社会管理者自身的道德修养;主张德刑兼治、德主刑辅,重德治、轻刑政;主张宽猛相济,先教后刑;主张富而后教,强调社会道德教化,重视道德对人们行为的规范作用。儒家的德刑观在中国社会长期的历史发展中产生了深远的影响,今天仍然可以为我们的道德建设和法制建设提供许多有益的借鉴和启示。
