Data on youth emotional and behavioral problems from societies in Sub-Saharan Africa are lacking. This may be due to the fact that few youth mental health assessments have been tested for construct validity of syndrome structure across multicultural societies that include developing countries, and almost none have been tested in Sub-Saharan Africa. The Youth Self-Report (YSR), for example, has shown great consistency of its syndrome structure across many cultures, yet data from only one developing country in Sub-Saharan Africa have been included. In this study, we test the factor structure of YSR syndromes among Kenyan youth ages 11–18 years from an informal settlement in Nairobi, Kenya and examine sex-differences in levels of emotional and behavioral problems. We find the eight syndrome structure of the YSR to fit these data well (Root Mean Square Error of Approximation = 0.049). While Kenyan girls have significantly higher internalizing (Anxious/Depressed, Withdrawn/Depressed, Somatic) problem scores than boys, these differences are of similar magnitude to published multicultural findings. The results support the generalizability of the YSR syndrome structure to Kenyan youth and are in line with multicultural findings supporting the YSR as an assessment of emotional and behavioral problems in diverse societies. 相似文献

We conducted two studies to explain inconsistent findings on the effect of resource inequality based on two properties of heterogeneity: (a) level of inequality and (b) asymmetry of resource distribution. We confirmed that symmetrically heterogeneous groups cooperated less than homogeneous groups did. We also found that larger resource inequality led to less cooperation. More importantly, the effect of inequality was different among groups with different distributions of resources – cooperation declined in groups with a symmetrical distribution of resources but did not decline in groups with a hegemonic distribution. Hegemonic distribution also affected psychological states as resource inequality changed. High endowment members reported higher self-efficacy when distribution was hegemonic than symmetric. However, they also reported more fear of being a sucker in hegemonic groups. 相似文献

Cultural ethical dilemmas occur when ethical research practices, as prescribed by the research ethics codes of Western research institutions, conflict with the cultural and social norms of non-Western researchers and their participants. Thus, insider-researchers working with participants from similar cultural backgrounds may experience ethical dilemmas that result in disconcerting cultural estrangement from their communities. Using reflexive narratives, the author identifies moments of cultural ethical dilemmas that necessitate a choice between two competing sets of values. Working out of a Western university, the narratives reflect on cultural ethical dilemmas relating to non-coercion, confidentiality, and beneficence, encountered during interviews in the researcher’s community. Analyzed through the lens of Confucian social and ethical behavior, the paper asks whether there is a need for East–west polarization, or whether research ethics codes based on Western worldviews can be reconciled with Confucian worldviews. The paper suggests the “Middle Way” approach to reconciling and integrating the diverse worldviews of ethics, through the use of an ethical reflexive process that engenders trust in the research process and resolves cultural ethical dilemmas. 相似文献

This paper develops a theory of analog representation. We first argue that the mark of the analog is to be found in the nature of a representational system's interpretation function, rather than in its vehicles or contents alone. We then develop the rulebound structure theory of analog representation, according to which analog systems use interpretive rules that map syntactic structural features onto semantic structural features. The theory involves three degree-theoretic measures that capture three independent ways in which a system can be more or less analog. We explain how our theory improves upon prior accounts of analog representation, provides plausible diagnoses for novel challenge cases, extends to hybrid systems that are partially analog and partially symbolic, and accounts for some of the advantages and disadvantages of representing analogically versus symbolically. 相似文献

An attempt to construct a general theory of duration perception is presented. First, four experiments are reported in which the supplement hypothesis, on the relation between two or three empty durations, was examined: the subjective duration of a subjectively empty time interval is directly proportional to its physical duration plus a constant of approximately 80 ms. This hypothesis could be applied to the ratio judgments of auditorily marked empty durations between 40 and 600 ms given serially. It could also explain the discrepancies between musically notated rhythms and the corresponding physical performed rhythms in very simple rhythm patterns consisting of three tones. Next, three earlier experiments on discriminations of empty durations marked by sound bursts were also reanalyzed. Within the range 40-600 ms, the absolute just noticeable difference of an empty duration was almost directly proportional to the standard duration plus a constant of about 80 ms. If the supplement hypothesis is accepted, this means that the relative just noticeable difference of the subjective duration was constant. Finally, the processing time hypothesis is presented: subjective duration is directly proportional to the physical time required to process the given empty duration. This processing is considered to begin with the detection of the first marker, and to end approximately 80 ms after the detection of the second marker. 相似文献

A quick eye to anger: An investigation of a differential effect of facial features in detecting angry and happy expressions 下载免费PDF全文
Detection of angry and happy faces is generally found to be easier and faster than that of faces expressing emotions other than anger or happiness. This can be explained by the threatening account and the feature account. Few empirical studies have explored the interaction between these two accounts which are seemingly, but not necessarily, mutually exclusive. The present studies hypothesised that prominent facial features are important in facilitating the detection process of both angry and happy expressions; yet the detection of happy faces was more facilitated by the prominent features than angry faces. Results confirmed the hypotheses and indicated that participants reacted faster to the emotional expressions with prominent features (in Study 1) and the detection of happy faces was more facilitated by the prominent feature than angry faces (in Study 2). The findings are compatible with evolutionary speculation which suggests that the angry expression is an alarming signal of potential threats to survival. Compared to the angry faces, the happy faces need more salient physical features to obtain a similar level of processing efficiency. 相似文献

It is widely assumed that reinforcers are biologically relevant stimuli, or stimuli that have been associated with biologically relevant stimuli. However, brief, arbitrary stimuli have also been reported to have reinforcement-like effects, despite being unrelated to biologically relevant stimuli like food. The present study explored the potential reinforcement-like effects of brief stimuli across 5 experiments. In Experiments 1 through 4, pigeon subjects responded for food reinforcement and brief stimulus presentations in a 2-component multiple schedule. Neither baseline response rates nor resistance to change during disruption tests were systematically greater in a component with versus without brief stimulus presentations. Increasing the rate and duration of brief stimulus presentations in Experiment 4 did not reveal reinforcement-like effects when compared directly with food. In Experiment 5, pigeons chose between independent terminal links in a concurrent-chains procedure. Across conditions, varying the location, duration, and rate of brief stimulus presentations in the terminal links had no systematic effects on preference. In contrast, varying rates of food reinforcers resulted in large and reliable shifts in preference. Therefore, the present study found no systematic evidence that brief stimuli unrelated to food reliably increase response rates, resistance to change, or preference. These data demonstrate the value of systematic replication, and a behavioral momentum approach to assessing potential reinforcement-like effects. 相似文献

The transition to university can be stressful for first-year university students. Despite the fact where the feeling of worry is a shared symptom by various mental health issues, there is a lack of studies that investigate into this matter. As worry is a domain-specific construct, there is a need for a valid and reliable measure of worry specifically for university students. Hence, this study aimed to evaluate the psychometric properties of the Student Worry Scale (SWS), particularly in terms of its validity and reliability. For this purpose, the current study recruited a sample of 295 first-year students to evaluate the psychometric properties of SWS. Exploratory factor analysis yielded a five-factor structure of SWS, which explained 55.7% of the total variance. The yielded five factors were general worries, financial-related concerns, significant other’s well-being, academic concerns, and social adequacy concerns. Inter-correlations between the five factors were all significant (r ranged between 0.395 and 0.625). The SWS demonstrated good internal consistency in this study (Cronbach’s alpha ranged between 0.786 and 0.941). Overall, the SWS is psychometrically evidenced to be a reliable and valid content-based worry measure specifically for university students. 相似文献

Past research showed that people project their goals onto unknown others. The present research investigates whether they also rely on their motivational orientation in terms of regulatory mode (locomotion vs. assessment). In line with work on self-judgments, a stronger chronic personal focus on locomotion over assessment decreased predictions of others' experiences of nostalgia (Study 1) and increased predictions of others' preference for, motivation by, and evaluation of a transformational over a transactional leader (Study 2). Furthermore, an experimentally induced locomotion mode compared to an assessment mode increased peoples' predictions of others' motivation to reconcile after interpersonal conflict (Study 3). We examined process evidence via the Testing-Process-by-Interaction-Strategy: As predicted, effects only emerged under time pressure (vs. ample deliberation; Study 2) and for ingroup (vs. outgroup) members (Study 3). These findings suggest that people's regulatory mode is a basis for predicting others' reactions and preferences. We discuss implications and future research directions. 相似文献
