学前儿童在游戏中社交和认知类型发展的研究──中美跨文化比较

采用时间取样观察法,以录像对中美１５０名学前儿童在游戏中的社交和认知类型进行比较研究,结果表明：①学前儿童社会交往发展水平、认知发展水平、游戏难度随年龄的增长而提高;②学前儿童较高水平的认知游戏行为与较高水平的社会技能的发展相关联,社交水平与认知水平的发展相互影响;③中美学前儿童社交和认知能力发展进程具有一致性,游戏行为发展模式具有一致性;④中美学前儿童游戏的方式和内容、社交和认知水平存在显著差异,表明不同文化背景的制约性。     

From demonstration to theory in embodied language comprehension: A review

Recent findings in psychology, psycholinguistics, and neuroscience present a challenge to current amodal theories by suggesting that cognitive states are not disembodied in language comprehension. Accumulating behavioral evidence supporting this view is reviewed from research on processing of language describing concrete and abstract concepts. The extant embodied theories that support either a strong or a moderate embodied view are then presented, as are the perspectives that define how the researchers discuss the role of sensory-motor grounding in language processing. The article concludes by discussing several lines of research that might help distinguish between various theoretical approaches and resolve some of the fundamental issues that fuel much of the debate in the field.     

The supposed shame of aging female bodies and the saving grace of transience

Where does the supposed shame of older women's bodies come from? In this essay, I suggest that such shame is not a natural response to aging; rather, it is a culturally conditioned reaction to the patriarchal fantasy of female physical perfection. While certain norms and narratives within Christianity tacitly encourage women to pursue this fantasy, there are also resources within this tradition that can help us challenge the stigma assigned to older female flesh and affirm the goodness of bodies that have lived a long time. Simultaneously, aging itself can provide a lens for fruitfully rethinking some central Christian ideas.     

“Get Off My Property”: A Personal Narrative Addressing Violence Against African Americans by Law Enforcement Post–Hurricane Katrina

Thousands of African American New Orleanians were displaced in the aftermath of Hurricane Katrina. It appeared that every African American suddenly became a suspect, “fair game” to be hunted, especially by the police. This autoethnography chronicles the author's personal background, experiences, and resulting emotions of her father's encounter with law enforcement post–Hurricane Katrina. Law enforcement–initiated interventions are explored. The article concludes with recommendations for members of the counseling profession and law enforcement. Miles de personas afroamericanas de Nueva Orleans perdieron sus hogares como consecuencia del huracán Katrina. Y de repente, cada persona afroamericana pareció convertirse en sospechosa, “presa legítima” para la caza, especialmente por parte de la policía. Esta autoetnografía documenta los orígenes personales y experiencias de la autora, así como las emociones resultantes de la interacción de su padre con las fuerzas policiales tras el huracán Katrina. Se exploran las intervenciones iniciadas por las fuerzas policiales. El artículo concluye con una serie de recomendaciones para los profesionales de la consejería y las fuerzas policiales.     

Feature selection using Ant Colony Optimization (ACO) and Road Sign Detection and Recognition (RSDR) system

Road Sign Detection and Recognition (RSDR) is aimed to enable drivers maintain basic functionality with the aim of identifying and notifying driver through the existing restrictions so that the process is a success on the present widened road. Examples for RSDR include ‘traffic light ahead’ or ‘pedestrian crossing’ signs. An innovative RSDR system has been introduced which comprises of pre-processing, edge detection, feature extraction, features selection and Ensemble Fuzzy Support Vector Machine (EFSVM) classifier. Feature selection is carried out successfully by deployment of Ant Colony Optimization (ACO) algorithm to determine most prominent and definitive features. These features are then fed into the ensemble SVM to enable both road side traffic detection as well as recognition. Suggested system’s performance is analyzed and evaluated with respect to road signs having a capable recognition rate.     

Why reread? Evidence from garden-path and local coherence structures

Two eye-tracking experiments were conducted to compare the online reading and offline comprehension of main verb/reduced relative garden-path sentences and local coherence sentences. Rereading of early material in garden-path reduced relatives should be revisionary, aimed at reanalysing an earlier misparse; however, rereading of early material in a local coherence reduced relative need only be confirmatory, as the original parse of the earlier portion of these sentences is ultimately correct. Results of online and offline measures showed that local coherence structures elicited signals of reading disruption that arose earlier and lasted longer, and local coherence comprehension was also better than garden path comprehension. Few rereading measures in either sentence type were predicted by structural features of these sentences, nor was rereading related to comprehension accuracy, which was extremely low overall. Results are discussed with respect to selective reanalysis and good-enough processing.     

The paradox of the universal triangle: Concepts,language, and prototypes

For over 300 years, the humble triangle has served as the paradigmatic example of the problem of abstraction. How can we have the idea of a general triangle even though every experience with triangles is with specific ones? Classical cognitive science seemed to provide an answer in symbolic representation. With its easily enumerated necessary and sufficient conditions, the triangle would appear to be an ideal candidate for being represented in a symbolic form. I show that it is not. Across a variety of tasks—drawing, speeded recognition, unspeeded visual judgments, and inference—representations of triangles appear to be graded and context dependent. I show that using the category name “triangle” activates a more prototypical representation than using an arguably coextensive cue, “three-sided polygon”. For example, when asked to draw “triangles” people draw more typical triangles than when asked to draw “three-sided polygons”. Altogether, the results support the view that (even formal) concepts have a graded and flexible structure, which takes on a more prototypical and stable form when activated by category labels.     

Marital Expectations in Strong African American Marriages

The current exploratory study utilized a family strengths framework to identify marital expectations in 39 strong African American heterosexual marriages. Couples reflected on their marital expectations over their 10 or more years of marriage. Three themes emerged through qualitative analysis and the participants' own words were used in the presentation of the themes. African Americans indicated that there was growth in marital expectations over time, with marital expectations often beginning with unrealistic expectations that grew into more realistic expectations as their marriages progressed. Participants also indicated that core expectations in strong African American marriages included open communication, congruent values, and positive treatment of spouse. Finally, participants explained there is an “I” in marriage as they discussed the importance of autonomy within their marital relationships. Results are discussed in association with existing research and theory.
