The purpose of the present study was to examine the effects of 12-week exercise interventions on physical self-perceptions of male university students. The study also aimed to investigate the relationships between the changes in physical self-perceptions and the changes in some physiological measures after 12-week exercise programs. Forty-eight male university students aged from 19 to 25 years were enrolled in this study. Participants were randomly and equally assigned to swimming, running, cycling and control conditions. The Physical Self-Perception Profile was administered to all participants before and after 12-week exercise programs. Additionally, strength, maximal oxygen uptake (VO(2max)) and body compositions were assessed before and after interventions. Participants in the exercise groups attended swimming, running or cycling sessions for 40 min per day, 3 days per week with 60-70% of their heart rate reserves, while those in the control group did not attend any regular physical activity. The results of 4 × 2 × 5 MANOVA with the dimensions of physical self-perceptions as within-subject factor revealed that all groups including the control group revealed better physical-self-perceptions from pre- to post-test. Results of 4 × 2 × 3 MANOVA with physiological measures as within-subject factor revealed that VO(2max) values of participants in the swimming group improved more than the other groups. On the other hand, no significant differences were observed in strength scores and body fat levels among groups. Furthermore, no significant associations were obtained between the changes in physical self-perception dimensions and the physiological measures. 相似文献

Sörqvist, P. & Sætrevik, B. (2010). The neural basis of updating: Distinguishing substitution processes from other concurrent processes. Scandinavian Journal of Psychology, 51, 357–362. Most previous studies of updating processes have not been able to contrast processes of substituting items in memory with other concurrent processes. In the present investigation, we used a new task called “number updating” and an fMRI protocol to contrast the activation of trials that require item substitution (adding a new item to the working memory representation and suppressing an old item) with trials that involve no substitution (discarding the new item). Trials that require item substitution activated the dorsolateral prefrontal cortex, the posterior medial frontal cortex and the parietal lobes, areas typically seen activated for working memory tasks in general. Trials that do not require substitution activated the anterior medial frontal cortex. Studies examining executive functions have associated this area with cognitive conflict, and may represent suppression of the substitution processes. 相似文献

The aim of the present study was to investigate stress reactions, speeding, number of penalties and accident involvement among different driver groups (taxi drivers, minibus drivers, heavy vehicle drivers, and non-professional drivers). A total number of 234 male drivers participated in the study. The participants were asked to complete the Driver Stress Inventory (DSI) together with a demographic information form. Five dimensions of the DSI were measured; aggression, dislike of driving, hazard monitoring, fatigue proneness, and thrill-seeking. After controlling the effects of age and annual mileage, the results of the ANCOVAs revealed differences between different driver groups in terms of both risky driving behaviours and stress reactions in traffic. Regression analyses indicated that aggression, dislike of driving, and hazard monitoring dimensions of the DSI were related to accident involvement after controlling for the effects of age, annual mileage and driver group. Dislike of driving and thrill-seeking dimensions of the DSI were related to speeding on in-city roads. 相似文献

This study is one of the first to examine emotion socialization behaviors of Turkish mothers; it also provides information on psychometric properties of the Coping with Children’s Negative Emotions Scale (CCNES; Fabes et al. 1990) in a sample of Turkish mothers of preschoolers. Participants were mothers (M age = 35.07, SD = 4.14) of 141 children attending daycare centers in middle and upper-middle class suburbs of Istanbul. The patterns of inter-correlations between emotion socialization reactions and general child-rearing behaviors showed that they reflect related but different aspects of broader parenting styles. Both aspects of parenting displayed associations with child emotional reactivity in the expected direction, further confirming patterns previously revealed for emotion socialization in Western samples. The results also confirmed the six emotion socialization behaviors assessed by the CCNES and all dimensions had good internal consistencies. The pattern of inter-correlations among maternal emotion socialization behaviors, general child-rearing behaviors, and child negative emotionality confirmed construct validity of the instrument for Turkish mothers. 相似文献

The author examines the possible connection of predictors of future time orientation to romantic relationships with the opposite sex using the Future Time Orientation in Romantic Relationships Scale (FTORR; B. Öner, 2000b). The variables suggested as correlates with FTORR scores in B. Öner's (2000a) study were subjected to regression analysis. The results indicated that relationship satisfaction and an eagerness to break up negative relationships were negatively related to FTORR scores, whereas being a woman, experiencing jealousy, and the degree of selectivity in choosing a dating partner were positively related to FTORR scores. Caution and relationship commitment both predicted FTORR scores through the mediating effect of relationship satisfaction. The author discusses the implications of the findings. 相似文献

A group of 172 mild cognitive impairment (MCI) patients and 79 healthy control participants (HC) were tested on simple reaction time (SRT). There was a significant difference between MCI and HC in mean SRT. The test could be partitioned into five segments of 16 trials each, but RT's were not always available for each partition. However, scores from each segment for 166 MCI and 41 of the HC's were available. These data showed that a significant interaction between RT‐partition and diagnostic category was the main source of the difference between groups. The interaction indicated that MCI patients performed at about the same level as HC in the initial three of the five segments of the test, but were significantly impaired during the last two segments of the 80 trials. The results were interpreted as impaired sustained attention among a large part of the MCI group, and the study shows the importance of taking into account all avaliable data resulting from this type of test. 相似文献

Electroencephalographic (EEG) frontal alpha asymmetry (FAA) and frontal midline (FM) theta have been suggested as biomarkers for depression and anxiety, but have mostly been assessed in small and non‐clinical studies. In a clinical sample of 79 adults with depression (ICD‐10: F32), resting EEG and scales of depression (MADRS) and anxiety (HADS‐A) were measured at intake and after 3 months. FAA and FM theta values were referenced to a normative population database. Internal consistency, test‐retest reliability, and correlations with psychiatric tests were examined. Reliability was sufficient. However, FAA and FM theta values were close to the general population, and correlations with psychiatric tests were mostly small and non‐significant, with the exception of FAA on F7–F8 z‐scores and HADS‐A. We conclude that the validity of FAA and FM theta and therefore their potential as biomarkers for depression and anxiety remain unclear. 相似文献
