Labeling guides object individuation in 12-month-old infants

A new manual search method was used to investigate the impact of naming on object individuation in 12-month-old infants. In Experiment 1, on a two-word trial, an experimenter looked into a box while the infant was watching and provided two labels (e.g., "Look, a fep!" and "Look, a wug!"). On a one-word trial, the experimenter instead repeated the same label (e.g., "Look, a zav!"). After the infant retrieved one object from the box, subsequent search behavior was recorded. Infants searched more persistently (i.e., for a longer duration) after hearing two labels than one, suggesting that hearing two labels led the infants to expect two objects inside the box. In Experiment 2, infants' search behavior did not differ depending on whether they heard one or two emotional expressions, suggesting that the facilitation effect observed in Experiment 1 may be specific to linguistic expressions. Thus, we provide the first evidence that infants as young as 12 months are able to use intentional and referential cues to guide their object representations. These findings also suggest that a rudimentary version of the mutual-exclusivity constraint may be functional by the end of the first year.     

The role of language in acquiring object kind concepts in infancy

Four experiments investigated whether 9-month-old infants could use the presence of labels to help them establish a representation of two distinct objects in a complex object individuation task. We found that the presence of two distinct labels facilitated object individuation, but the presence of one label for both objects, two distinct tones, two distinct sounds, or two distinct emotional expressions did not. These findings suggest that language may play an important role in the acquisition of sortal/object kind concepts in infancy: words may serve as "essence placeholders". Implications for the relationship between language and conceptual development are discussed.

情绪生理机制研究的外周与中枢神经系统整合模型

阐明人类情绪的生理机制是心理学家和神经科学家所面临的巨大挑战。以往研究倾向于分别考察情绪的外周反应模式和脑机制。近年来,随着情绪电生理学和认知神经科学的发展,许多研究者从外周与中枢神经系统相互作用的角度,提出了一些解释情绪生理机制的整合模型。其中,以情绪环路模型和神经内脏整合模型为典型代表。前者强调由外周到中枢的自下而上的加工方式,试图说明情绪经验形成的机制;后者则采取由中枢到外周的自上而下的加工方式,试图阐明情绪调控的机制。今后的研究有必要借鉴这两个模型,并结合近期有关情绪信息加工神经机制的新成果,以便构建能够更为全面解释人类情绪的生理模型。     

口腔种植诊疗实践中的思考

口腔种植现已经出现在人们的视线里,它具有一定的特殊性和优越性,能够解决常规修复手段不能解决的问题,然而在临床应用中,需要考虑和处理的问题往往很复杂。因此有必要在临床实践中运用辩证思维及循证医学的思想,在诊断中全面考虑、周密计划;在治疗中处理问题、解决难点;在随访中发现问题,促进发展。     

宗教与心理健康关系的研究综述

近年来,国外学者对宗教与心理健康关系进行了大量的研究.宗教总体上与更健康的心理,更多的幸福感,更低的抑郁、焦虑水平以及更低的自杀率有关.生命意义感、健康行为和社会支持很可能是影响宗教与心理健康关系的中间因素.在分析这一领域研究存在的问题的基础上,对在国内开展相关研究进行展望.

农村最低生活保障制度的伦理问题探讨

农村最低生活保障制度是一项具有浓厚伦理意蕴的社会制度,有着自身的伦理诉求:以人为本、社会公正及社会融合,但在运行各环节中也出现了许多伦理失范,如观念扭曲异化、多重标准纠结及生活世界殖民化等问题。矫治农村低保制度伦理失范,应树立政府"公共人"角色意识,规范优化政府行为;进行伦理价值取向定位,建构共享价值观体系;重塑乡村社会信任,建构利益沟通协调体系。     

Body Surveillance Predicts Men’s and Women’s Perceived Loneliness: A Serial Mediation Model

Previous research on self-objectification mainly focuses on its influences on intrapersonal psychological distress whereas our study examined whether self-objectification would influence interpersonal distress (i.e., loneliness) and its corresponding mechanisms in a sample of American women and men recruited with MTurk. Participants’ self-objectification was indexed by their level of body surveillance, and we proposed that body surveillance would increase women’s and men’s tendency to experience shame about their body and decrease their general self-esteem, which would in turn predict their level of loneliness. A total of 373 Americans (235 women; Mdn_age?=?33 years-old, range?=?18–77) participated in the present study, and the results provided support for the proposed theoretical model. Specifically, we found that body surveillance positively predicted people’s body shame, and body shame negatively predicted self-esteem, which in turn predicted people’s loneliness. Moreover, this mediational model was not different between men and women. These results expand the scope of investigation by incorporating male samples, and they suggest that in addition to intrapersonal consequences, self-objectification can also influence people’s interpersonal well-being. Implications were discussed.
