Cross-sectional studies on perfectionism and general affect tend to interpret their findings suggesting affect is an outcome of perfectionism. However, personality theories posit that individual differences in general affect may also influence perfectionism. Expecting to find bidirectional relations, this 3-wave study sought to examine the longitudinal interplay between perfectionism and general affect in a sample of 489 adolescents (54% female) aged 12–19 years. Cross-lagged panel analyses showed a positive unidirectional effect from positive affect to perfectionistic standards as well as a positive bidirectional effect between perfectionistic concerns and negative affect. As expected, general affect was both an antecedent and an outcome of perfectionism. Implications of the findings for the development and outcomes of perfectionism are discussed. 相似文献

ABSTRACTThe Flourishing Scale (FS) and the Scale of Positive and Negative Experience (SPANE) are scales that are newly introduced to evaluate well–being. The present study aims to assess the psychometric distinctive features of two scales by utilising two different Turkish samples: university students (n?=?320), and employees (n?=?180). Confirmatory factor analysis results demonstrate that a one-factor model of the FS and a two–factor model of the SPANE yield significant findings in those samples. Scales’ factorial structures are valid for gender groups also they have good internal consistency. Concurrent validity, and discriminant validity with the use of several conceptually related and unrelated measures in two samples reveal satisfactory validity results for both the FS and the SPANE. The results of the present study show the utility of these scales in Turkish culture. 相似文献

The internal processes involved in synchronizing our movements with environmental stimuli have traditionally been addressed using regular metronomic sequences. Regarding real-life environments, however, biological rhythms are known to have intrinsic variability, ubiquitously characterized as fractal long-range correlations. In our research we thus investigate to what extent the synchronization processes drawn from regular metronome paradigms can be generalized to other (biologically) variable rhythms. Participants performed synchronized finger tapping under five conditions of long-range and/or short-range correlated, randomly variable, and regular auditory sequences. Combining experimental data analysis and numerical simulation, we found that synchronizing with biologically variable rhythms involves the same internal processes as with other variable rhythms (whether totally random or comprising lawful regularities), but different from those involved with a regular metronome. This challenges both the generalizability of conclusions drawn from regular-metronome paradigms, and recent research assuming that biologically variable rhythms may trigger specific strong anticipatory processes to achieve synchronization. 相似文献

The vertical ground reaction force (VGRF) during rear-foot striking running typically exhibits peaks referred to as the impact peak and the active peak; their timings and magnitudes have been implicated in injury. Identifying the structure of time-series can provide insight into associated control processes. The purpose here was to detect long-range correlations associated with the time from first contact to impact peak (TIP) and active peak (TAP); and the magnitudes of impact (IPM) and active peaks (APM) using a Detrended Fluctuation Analysis, and Auto-Regressive Fractionally Integrated Moving Average models. Twelve subjects performed an 8 min trial at their preferred running speed on an instrumented treadmill. TIP, TAP; IPM, and APM were identified from the VGRF profile for each footfall. TIP and TAP time-series did not demonstrate long-range correlations, conversely IPM and APM time-series did. Short range correlations appeared as well as or instead of long range correlations for IPM. Conversely pure powerlaw behaviour was demonstrated in 11 of the 24 time series for APM, and long range dependencies along with short range correlations were present in a further 9 time series. It has been hypothesised that control mechanisms for IPM and APM are different, these results support this hypothesis. 相似文献
