The hypothesis that salivary cortisol would increase and salivary immunoglobulin A (IgA) decrease after a kickboxing match was tested among 20 male athletes. Saliva samples collected before and after the match were analyzed. Salivary cortisol and salivary IgA concentrations (absolute concentration, salivary IgAabs) and the secretion rate of IgA (salivary IgArate) were measured by enzyme-linked immunosorbent assay. A Wilcoxon test for paired samples showed significant increases in salivary cortisol from pre- to postmatch. No significant changes were observed in salivary IgAabs or secretory IgArate and saliva flow rate. This study indicates that a kickboxing match might increase salivary concentration and thereafter it could be considered a significant source of exercise-related stress. On the other hand, the effect of a kickboxing match on mucosal immunity seems not to be relevant. 相似文献

During stock market losses in 2009 and high unemployment, ratings on the KJP Dream Inventory were correlated with factors of the Money Attitude Scale and items on the Contemporary Financial Stress Inventory for 71 graduate students in Counseling Psychology and Education. Correlations were significant for Retention on the Money Attitude Scale with Dissociative Avoidance (-.31), Dreams of falling (.26), Risk-taking in dreams (.24), and Dreaming of being chased (.28). Also, ratings for the Money Attitude Scale of Distrust correlated with Discontentedness in dreams (.33) and Dreams of being chased (.26), Repetitive trauma (.33), Nightmares (.30), and Recurring nightmares (.35). Concern about retention in graduate school due to finances correlated with recalled frequencies of nightmares (.27) and dreams of flying (.25). 相似文献

RESUMENAlgunos autores de la psicología han definido el oído absoluto como la capacidad de identificar la frecuencia o nombre musical de un tono específico o, también como la aptitud para producir alguna frecuencia determinada sin compararla con cualquier otro sonido de referencia. Algunos datos parecen observar que esta capacidad es más una desventaja que ventaja. Los trabajos para intentar medir esta capacidad presentan muchos problemas, éstos serán analizados a lo largo del artículo. También se hará una revisión de las distintas teorías sobre su etiología, así como de las perturbaciones que pueden producirse tanto a nivel neurofisiológico como psicológico en relación con el oído absoluto. También se nombran brevemente las utilidades que proporciona el oído absoluto en el campo artístico. 相似文献

Objective: This study tested whether social cognitions from the reasoned action approach (RAA) can be reliably measured in a sample of primary school children (aged 4–6 years) and whether these RAA measures are predictive of physical activity.Design: Longitudinal observational study with repeated measures over six months.Measures: RAA variables were measured using a novel choice paradigm between physically active and sedentary pastimes. Relative reinforcing value, covariates (sex, age, deprivation and BMI) and physical activity by accelerometry (primary outcome) were also measured.Results: RAA cognitions could be measured with acceptable retest reliability and discriminant validity and social norms regarding parents and teachers (but not friends) were correlated with physical activity and change in physical activity when relative reinforcing value and other covariates were controlled for.Conclusions: RAA cognitions can be reliably measured in primary school children aged 4–6 and RRA measures appear useful in understanding children’s activity choices and may potentially inform future interventions. 相似文献

Categories, as mental structures, are more than simply sums of property frequencies. A number of recent studies have supported the view that the properties of categories may be organised along functional lines and possibly dependency structures more generally. The study presented here investigates whether earlier findings reflect something unique in the English language/North American culture or whether the functional structuring of categories is a more universal phenomenon. A population of English-speaking Americans was compared to a population of Cantonese-speaking Hong Kong Chinese. The findings clearly support the view that functional influences on category centrality are universal (or at least common to Cantonese-speaking Hong Kong Chinese and English-speaking Americans), albeit with specific cross-cultural/cross-linguistic group differences in the particular properties that are considered central to categories. 相似文献

This study aimed to understand the nature of nurturing and restraining relationships in a school communiy. The inquiry entailed a single instrumental case study of a selected school community in a semi-urban context in South Africa. Participants were learners (n=720), teachers (n=33) and administrative and terrain staff members (N=8) as well as two parents. Data on participants' perceptions of relationships in the school community were collected using work sessions/nominal group techniques, visual representations, and focus group interviews. Thematic analysis of the data revealed connectedness, respect, care and transparent communication as aspects that nurture relationships. Limited connectedness between people, the abuse of power, shifting of responsibility and disrespect for one another were revealed as aspects that restrain relationships. 相似文献

The interference produced by the viewing of emotional distractors has been interpreted as evidence that emotional cues are processed in a fairly mandatory fashion, and that they divert attention from the primary ongoing task. However, few studies have examined how behavioral emotional interference varies with repeated presentation of the same emotional distractors. In two experiments, while participants were engaged in a parity judgment task, we investigated the effects of repetition of task-irrelevant emotional pictures, as reflected in both behavioral interference (Experiments 1 and 2) and neural activity (Experiment 2). Both experiments showed that the slowing of reaction times that was observed when viewing emotional, compared to neutral, scenes disappeared after only a few repetitions, suggesting diminished attention allocation to repeated emotional pictures. Conversely, in Experiment 2, neural correlates of picture processing revealed that the late positive potential (LPP) amplitude continued to be enhanced for emotional, compared to neutral, distractors despite picture repetition and the presence of a concurrent task. Altogether, these findings suggest that while evaluative processes are mandatory, and continue to engage cortico-limbic appetitive and defensive systems even after massive repetition, as suggested by the affective modulation of the LPP, attentional processes are not necessary after several repetitions of the same stimulus, as indicated by the rapid decline of behavioral emotional interference. 相似文献
