When constructed in linear terms, cultures and identities misrepresent other people, constructing crisp boundaries that separate groups as if completely different. To demonstrate the negative impact of such views, I analyze cultural texts such as songs, films, and Web pages, showing the intercultural complexity existing in different constructions of Mexicanness as part of the dialogue arising in the political, social, and cultural interaction between Mexico and the United States. I emphasize the contrast between examples that reinforce identities that can be interpreted as fuzzy and inclusive, against those promoting and generating discrimination and exclusion.  相似文献

Automatic imitation or “imitative compatibility” is thought to be mediated by the mirror neuron system and to be a laboratory model of the motor mimicry that occurs spontaneously in naturalistic social interaction. Imitative compatibility and spatial compatibility effects are known to depend on different stimulus dimensions—body movement topography and relative spatial position. However, it is not yet clear whether these two types of stimulus–response compatibility effect are mediated by the same or different cognitive processes. We present an interactive activation model of imitative and spatial compatibility, based on a dual‐route architecture, which substantiates the view they are mediated by processes of the same kind. The model, which is in many ways a standard application of the interactive activation approach, simulates all key results of a recent study by Catmur and Heyes (2011) . Specifically, it captures the difference in the relative size of imitative and spatial compatibility effects; the lack of interaction when the imperative and irrelevant stimuli are presented simultaneously; the relative speed of responses in a quintile analysis when the imperative and irrelevant stimuli are presented simultaneously; and the different time courses of the compatibility effects when the imperative and irrelevant stimuli are presented asynchronously.  相似文献

In contrast to the psychological literature on adolescent smoking, little research has investigated the social identities of adult smokers. This study aimed to identify shared ‘smoking identities’ amongst a sample of 64 British smokers from different socio-economic groups using Q-methodology. Participants were asked to sort 70 items concerning smoking and smokers according to their agreement/disagreement with them. The 64 Q-sorts were then subjected to a by-person factor analysis yielding six factors, with the first four interpretable factors being presented here. Each factor is understood to represent a distinct ‘identity position’. The first two, the ‘addicted’ smoker, and the ‘in control’ smoker, oriented around a biomedical model of smoking as an addictive health risk. The final two, the ‘no big deal’ smoker and the ‘proud’ smoker reflected alternative understandings and values. The identity positions also differed in the extent to which smoking was considered a core part of self-identity. Unpacking the ‘smoking identities’ of current smokers offers the opportunity to devise targeted health promotion.  相似文献

Children often talk themselves through their activities, producing private speech that is internalized to form inner speech. This study assessed the effect of articulatory suppression (which suppresses private and inner speech) on Tower of London performance in 7- to 10-year-olds, relative to performance in a control condition with a nonverbal secondary task. Experiment 1 showed no effect of articulatory suppression on performance with the standard Tower of London procedure; we interpret this in terms of a lack of planning in our sample. Experiment 2 used a modified procedure in which participants were forced to plan ahead. Performance in the articulatory suppression condition was lower than that in the control condition, consistent with a role for self-directed (private and inner) speech in planning. On problems of intermediate difficulty, participants producing more private speech in the control condition showed greater susceptibility to interference from articulatory suppression than their peers, suggesting that articulatory suppression interfered with performance by blocking self-directed (private and inner) speech.  相似文献

ObjectivesEarlier qualitative researchers studying athletes’ dual careers (DCs) have shown that sociocultural discourses on gender are ingrained in DC policies and practices, creating gender inequalities and hierarchies. In this study, we aimed to extend this body of research by examining how Finnish elite youth ski coaches discursively construct athletes’ education and gender in their talk and coaching practices. Similarly, we examined how coaches’ beliefs about athletes' holistic development are interlinked with broader sociocultural discourses on gender.DesignQualitative study.MethodsWe conducted semi-structured interviews with 10 Finnish ski coaches (seven male, three female) aged 25–62 years (M = 38.5), and then analyzed the data using reflexive thematic analysis, interpreted through a feminist poststructuralist lens.FindingsCoaches’ discursive practices regarding education depended on their athletes' ages. For athletes in secondary education, the coaches predominantly drew on DC discourses that emphasized the compatibility of sports and education, but for athletes transitioning to senior-level sports, they drew on dominant performance discourses, believing that athletes at the senior level should prioritize their sports. Moreover, coaches discursively constructed athletic development as especially important for female athletes, who were perceived as less capable of excelling in sports and therefore needing to invest in multiple careers.ConclusionsBy drawing on gender stereotypes and binary understandings of gender, the coaches discursively reproduced gender hierarchies and unequal power relations in sports. These gendered discourses influence athletes' DC aspirations and the gendering of DC pathways.  相似文献

Adjustments of preplanned steps are essential for fall avoidance and require response inhibition. Still, inhibition is rarely tested under conditions resembling daily living. We evaluated the ability of young and older adults to modify ongoing walking movements using a novel precision step inhibition (PSI) task combined with an auditory Stroop task.Healthy young (YA, n = 12) and older (OA, n = 12) adults performed the PSI task at 4 individualized difficulty levels, as a single and dual task (DT). Subjects walked on a treadmill by stepping on virtual stepping stones, unless these changed color during approach, forcing the subjects to avoid them. OA made more failures (40%) on the PSI task than YA (16%), but DT did not affect their performance. In combination with increased rates of omitted Stroop task responses, this indicates a “posture first” strategy. Yet, adding obstacles to the PSI task significantly deteriorated Stroop performance in both groups (the average Stroop composite score decreased by 13% in YA and 27% in OA). Largest deficit of OA was observed in rates of incorrect responses to incongruent Stroop stimuli (OA 35% and YA 12%), which require response inhibition. We concluded that the performance of OA suffered specifically when response inhibition was required.  相似文献

Evidence from dual-task performance indicates that speakers prefer not to select simultaneous responses in picture naming and another unrelated task, suggesting a response selection bottleneck in naming. In particular, when participants respond to tones with a manual response and name pictures with superimposed semantically related or unrelated distractor words, semantic interference in naming tends to be constant across stimulus onset asynchronies (SOAs) between the tone stimulus and the picture–word stimulus. In the present study, we examine whether semantic interference in picture naming depends on SOA in case of a task choice (naming the picture vs reading the word of a picture–word stimulus) based on tones. This situation requires concurrent processing of the tone stimulus and the picture–word stimulus, but not a manual response to the tones. On each trial, participants either named a picture or read aloud a word depending on the pitch of a tone, which was presented simultaneously with picture–word onset or 350 ms or 1000 ms before picture–word onset. Semantic interference was present with tone pre-exposure, but absent when tone and picture-word stimulus were presented simultaneously. Against the background of the available studies, these results support an account according to which speakers tend to avoid concurrent response selection, but can engage in other types of concurrent processing, such as task choices.  相似文献

Research suggests that the defensive strategy used by people who score high on attachment-related avoidance when they encounter interpersonal threats involves two stages: automatic vigilance followed by effortful avoidance. In two studies we varied stimulus exposure times and cognitive load to determine how attention is regulated by avoidant individuals. Results indicate that avoidant individuals were vigilant toward contempt faces when the faces were presented for 100 ms but quickly disengaged from them when the faces were presented for 750 ms. Moreover, avoidant participants could disengage from contempt faces presented for 750 ms while rehearsing a simple 1-digit number, but not when rehearsing a 7-digit number, suggesting that avoidant disengagement is a cognitively effortful process. Theoretical and practical implications are discussed.  相似文献

It is natural to assume that the fine‐grained and highly accurate spatial information present in visual experience is often used to guide our bodily actions. Yet this assumption has been challenged by proponents of the Two Visual Systems Hypothesis (TVSH), according to which visuomotor programming is the responsibility of a “zombie” processing stream whose sources of bottom‐up spatial information are entirely non‐conscious (Clark, 2007, 2009; Goodale & Milner, 1992, 2004a; Milner & Goodale, 1995/2006, 2008). In many formulations of TVSH, the role of conscious vision in action is limited to “recognizing objects, selecting targets for action, and determining what kinds of action, broadly speaking, to perform” (Clark, 2007, p. 570). Our aim in this study is to show that the available evidence not only fails to support this dichotomous view but actually reveals a significant role for conscious vision in motor programming, especially for actions that require deliberate attention.  相似文献

ObjectivesThis project responds to the call for athletic career development and transitions research that centralizes the constitutive role of culture in athletes' experiences (Stambulova & Alfermann, 2009; Stambulova & Ryba, 2014). Within, we explore the cultural transitions of Aboriginal hockey players (14–22 years old) relocated into “mainstream” (Euro-Canadian) cultural contexts to pursue dual careers as students and athletes.DesignThe research was framed as a cultural sport psychology initiative. The project was rooted in a local Indigenous decolonizing methodology, which was brought forward via a participatory action research approach.MethodsMandala drawings and conversational interviews were employed as open-ended data collection processes that enabled the participants to share their stories and meanings through their own cultural perspectives. Vignettes were then used to present their accounts.ResultsThe participants' careers as athletes and students were precariously navigated within larger cultural tensions to: (a) deal with a loss of belonging in the Aboriginal community; (b) break down negative stereotypes and attitudes that Aboriginal people are not able to “make it”; and (c) give back to the Aboriginal communities they relocated away from.ConclusionsThrough a culturally resonant mode of knowledge production, the research uncovers contextual understandings of the cultural transitions experienced by Aboriginal athletes, revealing how this transition intersects with and shapes their dual careers. The project offers insight into the central role of culture in shaping athletes' dual careers, and provides impetus for more idiosyncratic approaches to be adopted in future research.  相似文献
