The brutal murder of James Byrd Jr. in June 1998 unleashed a storm of media, interest groups, high profile individuals and criticism on the Southeast Texas community of Jasper. The crime and subsequent response—from within the community as well as across the world—engulfed the entire town in a collective trauma. Using natural disaster literature/theory and employing an ecological approach, Jasper, Texas was investigated via an interrupted time series analysis to identify how the community changed as compared to a control community (Center, Texas) on crime, economic, health, educational, and social capital measures collected at multiple pre- and post-crime time points between 1995 and 2003. Differences-in-differences (DD) analysis revealed significant post-event changes in Jasper, as well as a surprising degree of resilience and lack of negative consequences. Interviews with residents conducted between March 2005 and 2007 identified how the community responded to the crisis and augmented quantitative findings with qualitative, field-informed interpretation. Interviews suggest the intervention of external organizations exacerbated the severity of the events. However, using strengths of specific local social institutions—including faith based, law enforcement, media, business sector and civic government organizations—the community effectively responded to the initial threat and to the potential negative ramifications of external entities. 相似文献

ABSTRACTEveryday multitasking and its cognitive correlates were investigated in an older adult population using a naturalistic task, the Day Out Task. Fifty older adults and 50 younger adults prioritized, organized, initiated, and completed a number of subtasks in a campus apartment to prepare for a day out (e.g., gather ingredients for a recipe, collect change for a bus ride). Participants also completed tests assessing cognitive constructs important in multitasking. Compared to younger adults, the older adults took longer to complete the everyday tasks and more poorly sequenced the subtasks. Although they initiated, completed, and interweaved a similar number of subtasks, the older adults demonstrated poorer task quality and accuracy, completing more subtasks inefficiently. For the older adults, reduced prospective memory abilities were predictive of poorer task sequencing, while executive processes and prospective memory were predictive of inefficiently completed subtasks. The findings suggest that executive dysfunction and prospective memory difficulties may contribute to the age-related decline of everyday multitasking abilities in healthy older adults. 相似文献

ObjectiveCurrent health behavior models of physical activity (PA) suggest that not all PA intentions are translated into actual PA behavior, resulting in a significant intention-behavior gap (IBG) of almost 50%. These models further suggest that higher self-efficacy and specific planning can aid in decreasing this gap. However, as most evidence stems from between-person (trait level), questionnaire-based research, it is unclear how large short-term IBGs are, how self-efficacy and planning covary within-persons across time and whether they similarly predict smaller IBGs. It is likely that day-to-day changes in circumstances and barriers affect these variables thus the applicability of theoretical models is uncertain. Here, within-person prospective analyses of ecological momentary assessment (EMA) data can provide insights.Methods35 healthy participants (aged 23–67) completed four EMA-based questionnaires every day for three weeks. Each prompt assessed PA (retrospectively, “since the last EMA prompt”); PA intentions, planning specificity, self-efficacy, and intrinsic motivation (prospectively, “until the next EMA prompt”) and momentary affect. Generalized logistic mixed-effect modeling was used to test predictors of PA.ResultsAcross the 2341 answered EMA prompts, PA intentions were not enacted in 25% of the episodes (IBG). In episodes with given intentions, PA likelihood increased with higher levels of self-efficacy, planning specificity, and intrinsic motivation. The latter two also positively predicted PA duration and intensity.ConclusionsShort-term intention behavior gaps seem to be smaller than what is known from more long-term studies, most likely as individuals can anticipate the actual circumstances of PA. Further, current health behavior models show validity in explaining within-person dynamics in IBGs across time. Knowing the relevance of planning specificity, self-efficacy and intrinsic motivation for day-to-day variations in PA enactment can inform respective real-time mHealth interventions for facilitating PA. 相似文献

Non-representational approaches to cognition have struggled to provide accounts of long-term planning that forgo the use of representations. An explanation comes easier for cognitivist accounts, which hold that we concoct and use contentful mental representations as guides to coordinate a series of actions towards an end state. One non-representational approach, ecological-enactivism, has recently seen several proposals that account for “high-level” or “representation-hungry” capacities, including long-term planning and action coordination. In this paper, we demonstrate the explanatory gap in these accounts that stems from avoiding the incorporation of long-term intentions, as they play an important role both in action coordination and perception on the ecological account. Using recent enactive accounts of language, we argue for a non-representational conception of intentions, their formation, and their role in coordinating pre-reflective action. We provide an account for the coordination of our present actions towards a distant goal, a skill we call distal engagement. Rather than positing intentions as an actual cognitive entity in need of explanation, we argue that we take them up in this way as a practice due to linguistically scaffolded attitudes towards language use. 相似文献

ObjectivesEmerging evidence suggests both motivation and movement-related behaviors vary within and across days. Yet common data analytic approaches assume static or consistent relationships between motivation and behavior across time. Just as motivation and behavior change across time, so too might associations between motivation and behavior. This study will apply time-varying effect modeling to Ecological Momentary Assessment (EMA) data to examine time of day differences in how motivational constructs predict older adults’ subsequent movement-related behavior over the next 2 h.DesignOlder adults (n = 104) completed a 10-day EMA protocol.MethodParticipants answered up to 6 EMA prompts/day to assess momentary intentions and self-efficacy to stand or move as well as intentions and self-efficacy to limit sedentary time over the next 2 h. Participants wore an activPAL accelerometer continuously to measure time spent being upright (i.e., standing or moving) and time spent sitting.ResultsOn weekdays, intentions and self-efficacy were generally predictive of subsequent behavior in the expected direction over the majority of the day whereas these constructs predicted subsequent behavior in the expected directions over a smaller range of times on weekend days.ConclusionsThis study adds to emerging evidence that associations between motivational constructs and subsequent behavior change over the course of the day, but these time-varying associations may be different depending on the day of week. This work has implications for intervention design and the timing of intervention content delivery in approaches like just-in-time adaptive interventions. 相似文献

Can competitive paradigms increase the validity of experiments on primate social cognition? 总被引:5,自引:5,他引:0
Brian Hare 《Animal cognition》2001,4(3-4):269-280
Experiments vary in their ability to distinguish between competing hypotheses. In tests on primate cognition the majority
of this variation is due to an experimenter's ability to test primates in valid settings while providing the adequate amount
of experimental control. While experimenters studying primate cognition can use methods of control perfected in captivity,
it is still very unclear how to design and then objectively evaluate the external validity of new experimental paradigms.
I recommend that more effort be allocated to specify how to create relevant test settings for primates. Primate social life
is highly competitive. This means that all aspects of primates themselves, including their cognitive abilities, have likely
been shaped by the need to out-compete conspecifics. Based on this hypothesis, sophisticated cognitive abilities of primates
might best be demonstrated in competitive contexts. Thus, it is suggested that one possible measure of validity is whether
investigators integrate a competitive component into their experimental designs. To evaluate this methodological prediction
I review the literature on chimpanzee perspective-taking as a case study including several recent studies that include a competitive
component in their experimental designs.

Anatomically detailed dolls have been used to elicit testimony from children in sex abuse cases. However, studies have shown
they often provide false accounts in young, preschool-age children. Typically this problem is seen as a cognitive one: with
age, children can correctly map their bodies onto a doll due to greater intellectual ability to represent themselves. I argue, along with the work of Maurice Merleau-Ponty, that although cognitive developments aid in the ability
to represent one’s own body, a discussion of embodiment is required in order to understand the use and abuse of anatomical dolls in forensic interviews. This paper examines these
issues and maintains that a better understanding of embodied perception in both adults and children helps show how phenomenology
can provide a more nuanced understanding to a troubling ethical and legal problem.
