Living Conditions and Psychological Distress in Latino Migrant Day Laborers: The Role of Cultural and Community Protective Factors 下载免费PDF全文
Kurt C. Organista Samantha Ngo Torsten B. Neilands Alex H. Kral 《American journal of community psychology》2017,59(1-2):94-105
The purpose of this study was to examine the relationship between typically difficult living conditions and psychological distress in Latino migrant day laborers (LMDLs), with attention to the potentially protective roles of contact with family in country of origin (i.e., communication, sending money, etc.), availability of local culture (i.e., food, music, people from one's country of origin), and utilization of community resources perceived to be culturally competent (i.e., services that are respectful, able to serve Latinos, able to solve problems, in Spanish, etc.). Participants were 344 LMDLs surveyed in the San Francisco Bay Area. As hypothesized: (a) difficult living conditions were related to depression, anxiety, and desesperación [desperation], the latter a popular Latino idiom of psychological distress recently validated on LMDLs; (b) contact with family moderated the relation between difficult living conditions and depression and desesperación but not anxiety and (c) access to local culture, and utilization of community resources, mediated the relation between difficult living conditions and depression and desesperación but not anxiety. Implications for intervening at local and larger levels in order to provide some protection against distress built into the LMDL experience in the United States are discussed. 相似文献

A small number of species are capable of recognizing themselves in the mirror when tested with the mark-and-mirror test. This ability is often seen as evidence of self-recognition and possibly even self-awareness. Strangely, a number of species, for example monkeys, pigs and dogs, are unable to pass the mark test but can locate rewarding objects by using the reflective properties of a mirror. Thus, these species seem to understand how a visual reflection functions but cannot apply it to their own image. We tested this discrepancy in pigeons—a species that does not spontaneously pass the mark test. Indeed, we discovered that pigeons can successfully find a hidden food reward using only the reflection, suggesting that pigeons can also use and potentially understand the reflective properties of mirrors, even in the absence of self-recognition. However, tested under monocular conditions, the pigeons approached and attempted to walk through the mirror rather than approach the physical food, displaying similar behavior to patients with mirror agnosia. These findings clearly show that pigeons do not use the reflection of mirrors to locate reward, but actually see the food peripherally with their near-panoramic vision. A re-evaluation of our current understanding of mirror-mediated behavior might be necessary—especially taking more fully into account species differences in visual field. This study suggests that use of reflections in a mirrored surface as a tool may be less widespread than currently thought. 相似文献

Social anxiety disorder (SAD) is often treated as a discrete diagnostic entity that represents a naturally occurring class, though empirical evidence largely supports a dimensional conceptualization of social fears. Further, the inclusion of a “performance only” specifier in the DSM-5 implies that individuals who experience intense social anxiety exclusively in performance situations are distinct from those with broader social fears. The purpose of the present research was to examine the latent structure of SAD and the DSM-5 “performance only” specifier in a large nonclinical sample (n = 2019). Three taxometric procedures (MAXCOV, MAMBAC, and L-Mode) were applied to indicators derived from two commonly used measures of social anxiety. Results yielded convergent evidence indicating that social anxiety exhibits a dimensional latent structure. Further, social performance anxiety demonstrates continuous relationships with milder social fears, suggesting that the “performance only” specifier may not represent a discrete entity. The implications of these findings for the assessment, diagnosis, classification, and treatment of social anxiety are discussed. 相似文献

The ability of non-human animals to use experimenter-given cues in object-choice tasks has recently gained interest. In such
experiments, the location of hidden food is indicated by an experimenter, e.g. by gazing, pointing or touching. Whereas dogs
apparently outperform all other species so far tested, apes and monkeys have problems in using such cues. Since only mammalian
species have been tested, information is lacking about the evolutionary origin of these abilities. We here present the first
data on object-choice tasks conducted with an avian species, the common raven. Ravens are highly competitive scavengers, possessing
sophisticated cognitive skills in protecting their food caches and pilfering others’ caches. We conducted three experiments,
exploring (i) which kind of cues ravens use for choosing a certain object, (ii) whether ravens use humans’ gaze for detecting
hidden food and (iii) whether ravens would find hidden food in the presence of an informed conspecific who potentially provides
gaze cues. Our results indicate that ravens reliably respond to humans’ touching of an object, but they hardly use point and
gaze cues for their choices. Likewise, they do not perform above chance level in the presence of an informed conspecific.
These findings mirror those obtained for primates and suggest that, although ravens may be aware of the gaze direction of
humans and conspecifics, they apparently do not rely on this information to detect hidden food. 相似文献

The current article offers a brief history of research and theory related to social categorization and stereotyping. We begin by outlining research focusing on category selection, category activation, and category application. We then discuss the consequences of social categorization, noting that one of the most important and ubiquitous effects of social categorization is homogenization or assimilation. We then extend this research related to the assimilative consequences of social categorization to the realm of face memory. Specifically, we introduce the Categorization‐Individuation Model (see also Hugenberg et al., forthcoming) as a new model of the Cross‐Race Effect, or the difficulty many perceivers have in recognizing members of other racial groups. The Categorization‐Individuation Model argues that the Cross‐Race Effect is due to the tendency to categorize out‐group members but individuate in‐group members. Finally, we summarize the extant research in support of this new model of person memory and close by discussing the current state of, and potential future directions for, social categorization research. 相似文献
