The development of spatial visual attention has been extensively studied in infants, but far less is known about the emergence of object‐based visual attention. We tested 3–5‐ and 9–12‐month‐old infants on a task that allowed us to measure infants’ attention orienting bias toward whole objects when they competed with color, motion, and orientation feature information. Infants’ attention orienting to whole objects was affected by the dimension of the competing visual feature. Whether attention was biased toward the whole object or its salient competing feature (e.g., “ball” or “red”) changed with age for the color feature, with infants biased toward whole objects with age. Moreover, family socioeconomic status predicted feature‐based attention in the youngest infants and object‐based attention in the older infants when color feature information competed with whole‐object information.  相似文献

We examined maternal behavioral strategies in relation to infants' object‐directed actions in real time and over developmental time in 206 mother–infant dyads from African American, Dominican immigrant, and Mexican immigrant backgrounds. Mothers were asked to share a set of beads and strings with their infants when children were 14, 24, and 36 months. We coded three types of maternal strategies—eliciting attention, instructive assistance, and encouragement—which could be expressed verbally (e.g., “look”, “turn it”, “good job!”) or physically (i.e., through gestures, hands‐on guidance, or transfer of objects). We also coded infants' unassisted bead‐stringing. Across ethnic groups and ages, mothers' hands‐on guidance and object transfer increased the likelihood that infants would follow with unassisted bead‐stringing during real‐time interaction. Over developmental time, mothers modified their strategies: They displayed fewer attention‐getting strategies and more encouragement across infant ages, and peaked in their provision of instructive assistance when infants were 24 months. Additionally, Mexican mothers displayed more nonverbal strategies (e.g., gestures, hands‐on guidance) than did African American and/or Dominican mothers, who displayed more verbal strategies (e.g., attention‐getting and encouraging language). Developmental and real‐time patterns in mother–infant object‐related interactions generalize across ethnicities, although mothers' emphases on specific strategies are culture specific.  相似文献

“What happened? Why did it happen? What can be done to prevent it from happening again and again?” Voiced less that one week after the July 1967 race riots in Detroit, Michigan, Lyndon B. Johnson spoke these words as he ordered the establishment of the National Advisory Commission on Civil Disorders. Seven months later, on March 1, 1968, the Commission's account—known as the Kerner Commission Report—was a scathing appraisal of riots and racism in the United States. While it included bold language about the linkage between rioting and racism, it is rife with paradoxical assumptions and findings. Moreover, the report's failure to define sociological concepts, coupled with a reliance on individualism and cognitive attitudes via psycho‐analytic and pop‐psychological conjecture, together beckon scholars to wrestle with how this state‐issued report reflected and reproduced dominant assumptions about the “race” concept, violence, and human nature. Employing a critical content analysis of the report, I ask: How does the Kerner Commission Report define and use the concept of “riots” and “racism,” and what are the logics employed in the production of that knowledge?  相似文献

In the early 1990s, privileged “white” South African public schools began to admit “black” pupils. Drawing on interviews, ethnography, and archival sources related to formerly‐white schools in Durban, this article addresses two main questions: first, why did white parents so enthusiastically vote for schooling desegregation when apartheid was still in place?; and second, why, over time, did intense competition emerge between schools, and become so focused on improving sports results? In addressing these questions this study takes an historical‐geographical approach, paying particular attention to two areas of Durban: the middle‐class central Berea area and the more working‐class areas in Durban's south. This story begins in the 1950s, a period of major schooling expansion and urban segregation, tracing how a hierarchy of white schools developed in relation to the city's uneven geographies of race and class. It is this schooling hierarchy and the way it became contested in the 1990s that is key to understanding the schools' shift from “cooperative desegregation” to “aggressive competition.” More broadly, the article argues that education provides a window into key post‐apartheid tensions – namely between the deracialization of privilege, the continued dividend of whiteness, and efforts to redistribute resources to the poor. Finally, in an age of mass education, it argues that the actions of schools play an important role in shaping raced and classed divisions in society.  相似文献

Working with Judith Butler's Excitable Speech: A Politics of the Performative, this essay pursues a series of questions on the performativity of speech acts, using sexual innuendo as an example. As performed by the provocative American playwright and classic Hollywood film star, Mae West, sexual innuendo provides an instance of “excitable speech” that allows for the exploration of speech as a site of political resistance. The questions that frame this discussion are as follows: How are vulnerability and agency produced in speech? What are the foreclosures or censors at work in producing speech and the speaking subject? What constitutes the “force” of the performative speech act? How is the speech act repeatable? And do these conditions leave room for Butler's notion of linguistic agency, where the speech act works to undermine linguistic conventions through resignification? Finally, the essay offers queer readings of Mae West in order to demonstrate the concept of “discursive performativity,” which underpins Butler's argument.  相似文献

Abstract It is often said that the Japanese lack the firm consciousness of “self” namely, they yield to groups and are absorbed in an anonymous state. Some ascribe this to the Japanese language, in which the first and the second person are expressed by various pronouns (or, in many cases, are even omitted) in accordance with the relationships between persons. By contrast the Westerner's “I,” which is usually the only pronoun for the first-person, is rarely omitted. They conclude from this that the Japanese individual does not possess as clearly defined a conception of “self” as does the Westerner. Underlying this issue are the fundamental, interwoven questions of language and self-consciousness: does “self” really exist, and does the analysis of the I in language pertain to the first question? This paper discusses these questions by considering Wittgenstein's argument that “I” does not refer to self-consciousness: rather, “self” is a metaphysical reification of “I.” These problems concern sociology, in which the “subject” of action has been the focal point of methodological arguments. I will show that Meadian interactionism and critical theory are deeply rooted in the metaphysical, subjectivist understanding of “I,” while ethnomethodology offers a perspective which overcomes both subjectivism and objectivism for studying communication.  相似文献

Interruptions to parent–child interactions due to technology, or “technoference,” have been correlated with a host of negative child developmental outcomes. Yet, the influence of technoference on parent–infant interactions and infant behaviors has received less attention and more experimental work is warranted. For this study, parent–infant dyads (n = 227) completed a modified still‐face paradigm (SFP) using a mobile phone during the still‐face phase. Infant responses were coded for positive and negative affect, object and parent orientation, self‐comforting, and escape behaviors during the task. Results showed a robust still‐face effect, with infants displaying increased negative affect, decreased positive affect, increased self‐comforting, object orientation, and escape behaviors during the “still‐face” or phone distracted phase of the paradigm and frequently failing to return to baseline during the reunion phase. Older infants (older than 9 months) likewise demonstrated higher levels of negative affect across all three phases of the paradigm relative to younger infants (less than 9 months). Parent reports of technoference behavior were related to increased object orientation for younger infants. Parental technoference behaviors were also linked to more escape behaviors for younger infants and decreased object orientation in older infants during the still‐face portion of the SFP. Higher levels of technoference also appear to attenuate the negative emotional response of infants during still face. Results are discussed in relation to infants’ increasing exposure to digital technology in the context of early relationships.  相似文献

This paper presents a rationale and educational plan for teaching statistical orientation (not statistics per se) by means of a series of practice questions that are, at the same time, basic statistical questions. These questions include, for example, measures of central tendency, “What can typically be expected of the client's problem behavior?” and measures of variability, “What range of variation from the typical is typical?” Set in a context of practice, these types of questions do not seem to provoke the hostility among social work students that often typifies their reaction to traditional statistics courses.  相似文献

Halberda (2003) demonstrated that 17‐month‐old infants, but not 14‐ or 16‐month‐olds, use a strategy known as mutual exclusivity (ME) to identify the meanings of new words. When 17‐month‐olds were presented with a novel word in an intermodal preferential looking task, they preferentially fixated a novel object over an object for which they already had a name. We explored whether the development of this word‐learning strategy is driven by children’s experience of hearing only one name for each referent in their environment by comparing the behavior of infants from monolingual and bilingual homes. Monolingual infants aged 17–22 months showed clear evidence of using an ME strategy, in that they preferentially fixated the novel object when they were asked to “look at the dax.” Bilingual infants of the same age and vocabulary size failed to show a similar pattern of behavior. We suggest that children who are raised with more than one language fail to develop an ME strategy in parallel with monolingual infants because development of the bias is a consequence of the monolingual child’s everyday experiences with words.  相似文献

When do infants begin to communicate positive affect about physical objects to their social partners? We examined developmental changes in the timing of smiles during episodes of initiating joint attention that involved an infant gazing between an object and a social partner. Twenty‐six typically developing infants were observed at 8, 10, and 12 months during the Early Social‐Communication Scales, a semistructured assessment for eliciting initiating joint attention and related behaviors. The proportion of infant smiling during initiating joint attention episodes did not change with age, but there was a change in the timing of the smiles. The likelihood of infants smiling at an object and then gazing at the experimenter while smiling (anticipatory smiling) increased between 8 and 10 months and remained stable between 10 and 12 months. The increase in the number of infants who smiled at an object and then made eye contact suggests a developing ability to communicate positive affect about an object.  相似文献

Forms that are nonlinguistic markers in one language (i.e., “tsk‐tsk” in English) may be part of the phoneme inventory—and hence part of words—in another language. In the current paper, we demonstrate that infants' ability to learn words containing unfamiliar language sounds is influenced by the age and vocabulary size of the infant learner, as well as by cues to the speaker's referential intent. When referential cues were available, infants at 14 months learned words with non‐native speech sounds, but at 20 months only those infants with smaller vocabularies succeeded. When no referential cues were present, infants at both 14 and 20 months failed to learn the same words. The implications of the relation between linguistic sophistication and non‐native word learning are discussed.  相似文献

This research investigated infants’ (16 and 20 months) use of category information in responding to references to absent objects. Infants were asked to find an object in the box (e.g., “Find an apple!”). When allowed to search, they found either an object from the mentioned category (a plastic apple) or a different object. Infants in both age groups searched again in the box trying to find another object more often on nonreferent than on referent trials (Experiment 1). However, when nonreferents were categorically related to referents, only older infants detected a mismatch and searched again (Experiment 2). These findings suggest that infants use category knowledge when processing references to absent objects.  相似文献

What kind of featural information do infants rely on when they are trying to recognize a previously seen object? The question of whether infants use certain features (e.g., shape or color) more than others (e.g., luminance) can only be studied legitimately if visual salience is controlled, as the magnitude of feature values—how noticeable and interesting they are—will affect results. We employed a novel methodology, interdimensional salience mapping, that allowed us to quantify and calibrate salience changes along shape, luminance, and color feature dimensions. We then compared 9‐month‐old infants' identification of objects, employing feature changes that were equally salient. These results show that infants more readily identify objects on the basis of color and shape than luminance. Additionally, we show that relative salience changes rapidly in infancy—in particular, we found significantly higher salience thresholds for color in younger (6.5‐month‐old) infants—but that individual differences within an age group are remarkably modest.  相似文献

Three‐dimensional (3D) object completion, the ability to perceive the backs of objects seen from a single viewpoint, emerges at around 6 months of age. Yet, only relatively simple 3D objects have been used in assessing its development. This study examined infants’ 3D object completion when presented with more complex stimuli. Infants (N = 48) were habituated to an “L”‐shaped object shown from a limited viewpoint; then they were tested with volumetrically complete (solid) and incomplete (hollow) versions of the object. Four‐month‐olds and 6‐month‐old girls had no preference for either display. Six‐month‐old boys and both sexes at 9.5 months of age showed a novelty preference for the incomplete object. A control group (N = 48), only shown the test displays, had no spontaneous preference. Perceptual completion of complex 3D objects requires infants to integrate multiple, local object features and thus may tax their nascent attentional skills. Infants might use mental rotation to supplement performance, giving an advantage to young boys. Examining the development of perceptual completion of more complex 3D objects reveals distinct mechanisms for the acquisition and refinement of 3D object completion in infancy.  相似文献

This study explored whether infants understand information transmission in a third‐party communication context involving multiple agents. Infants aged 12 and 15 months were habituated to two agents pursuing two different objects and then tested with one agent (the communicator) interacting with a new agent (the recipient), whereas the other agent (the noncommunicator) did not interact with anyone. Results showed that 15‐month‐olds looked for longer when the recipient reached toward the preferred object of the noncommunicator in contrast to that of the communicator, suggesting that they recognized information transmitted from the communicator (versus the noncommunicator) to the recipient. Furthermore, the information was perceived as being specifically transmitted between agents, and this inference was not driven by the low‐level perceptual factors of the communicator or the communication itself. However, 12‐month‐old infants did not show an understanding of transmission between the agents. The selective understanding of information transmitted among multiple agents, and the critical role of agency in such understanding are discussed.  相似文献

At around their third birthday, children begin to enforce social norms on others impersonally, often using generic normative language, but little is known about the developmental building blocks of this abstract norm understanding. Here, we investigate whether even toddlers show signs of enforcing on others interpersonally how “we” do things. In an initial dyad, 18‐month‐old infants learnt a simple game‐like action from an adult. In two experiments, the adult either engaged infants in a normative interactive activity (stressing that this is the way “we” do it) or, as a non‐normative control, marked the same action as idiosyncratic, based on individual preference. In a test dyad, infants had the opportunity to spontaneously intervene when a puppet partner performed an alternative action. Infants intervened, corrected, and directed the puppet more in the normative than in the non‐normative conditions. These findings suggest that, during the second year of life, infants develop second‐personal normative expectations about their partner's behavior (“You should do X!”) in social interactions, thus making an important step toward understanding the normative structure of human cultural activities. These simple normative expectations will later be scaled up to group‐minded and abstract social norms.  相似文献

This study examines face‐scanning behaviors of infants at 6, 9, and 12 months as they watched videos of a woman describing an object in front of her. The videos were created to vary information in the mouth (speaking vs. smiling) and the eyes (gazing into the camera vs. cueing the infant with head turn or gaze direction to an object being described). Infants tended to divide their attention between the eyes and the mouth, looking less at the eyes with age and more at the mouth than the eyes at 9 and 12 months. Attention to the mouth was greater on speaking trials than on smiling trials at all three ages, and this difference increased between 6 and 9 months. Despite consistent results within subjects, there was considerable variation between subjects. This raises the question of whether a developmental “norm” of face scanning in infancy ought to be pursued. Rather, these data add to emerging evidence suggesting that individual differences in face scanning might reliably predict aspects of later development.  相似文献

Although the anonymous condition of on‐line interaction seems to provide space for the experiment of decentered, fluid, and multiple forms of identity, the disembodied on‐line identity often entails the fallout of accountability of self‐presentation. This article explores the nature of self‐presentation in cyberspace by conducting a case study of an on‐line discussion group. Specifically, it deals with the issue of disembodiment and accountability of on‐line identity in a close connection to the feature of the obliteration of the public/private boundary in the group. This study inquires into the following questions: “What techniques, if any, do members of the group employ to conceal their identity information?”; “Under what circumstances do members voluntarily disclose their identity information?”; “How do participants probe others’ identity cues and thus construct pattern knowledge about them?”; and “How should differences/similarities between on‐line self‐presentation and face‐to‐face identity styles be addressed?” In doing so, this article, on the one hand, tries to integrate the dynamics of participants’ active “identity probing” as an important interaction dimension to the study of on‐line self‐presentation that has so far heavily worked on the processes of identity concealment and self‐disclosure. On the other, referring to literatures on identity styles in off‐line settings, it addresses similarities of and differences between patterns of on‐line/off‐line self‐presentation.  相似文献

The flexible and cheap labour that European “post‐industrial” economies are in need of is often facilitated by undeclared labour. The undocumented migrant, from his/her part, relatively easily finds work that suits his ‐‐ at least initial ‐‐ plans. What lies behind this nexus between irregular migration and informal economy? To what extent can this nexus be attributed to the structural features of the so‐called “secondary”, as opposed to “primary”, labour market? And how does migration policy correlate with this economic context and lead to the entrapment of migrants in irregularity? Finally, can this vicious cycle of interests and life‐strategies be broken and what does the experience of the migrants indicate in this respect? This paper addresses these questions via an exploration of the grounds upon which irregular migration and the shadow economy complement each other in southern Europe (SE) and central and Eastern Europe (CEE) (two regions at different points in the migration cycle). In doing so, the dynamic character of the nexus between informal economy and irregular migration will come to the fore, and the abstract identity of the “average” undocumented migrant will be deconstructed.  相似文献

Clinical writers love to publish their success stories. Treatment failures get shuffled to the bottom drawer. Perhaps this is why there is so little in the clinical literature about a problem so frequently encountered by the clinical social worker: the patient or client who never shows up or doesn't return. Why don't they keep their appointments? What are the most common dynamics? How much of the problem rests with the client and how much with the clinician or agency? What should be done when your client “no-shows”? When should you do it? This paper will explore these questions in an attempt to deepen the practitioner's understanding and management of this common clinical challenge.  相似文献
