In this exploratory study, the authors examined the dynamics of self-esteem in 8 adults over a 6-month period. Each participant (M age = 29.4 years, SD = 7.9, SEM = 2.8) completed a single item from the Physical Self Inventory (G. Ninot, M. Fortes, & D. Delignières, 2001) using a 10-cm visual analog scale (horizontal line), twice a day between 7:00 and 9:00 a.m. and between 7:00 and 9:00 p.m. Time series analyses, including autocorrelation and autoregressive integrated moving average (ARIMA) procedures, showed that global self-esteem dynamics were neither stable, stationary, nor random. The ARIMA procedures indicated that this perceived dimension functioned as a moving average (0, 1, 1) without a significant constant, thus suggesting a short-term dynamic adjustment. This pattern is a typical signature of a complex system submitted to several constraints and not an indication of personality trait or state. 相似文献

Three experiments investigated whether the repeated-letter inferiority effect (RLIE) and repetition blindness (RB) are identical phenomena or not and how the RLIE can be reconciled with the flanker compatibility effect (FCE). Participants reported a masked target and ignored an unmasked distractor. We manipulated the type of distractor (identical, alternative target, or neutral), the order of presenting distractor and target, and the predictability of target location. When distractors preceded the targets, distractors identical to the target always caused deficits in target processing (i.e., RB). With simultaneous presentation, identical distractors caused deficits (i.e., an RLIE) for unpredictable target locations only. Yet the RLIE was significantly smaller than RB. This result suggests that simultaneously presented stimuli are identified serially, in random order, if target position is unpredictable. As a result, RB arises only in the 50% of all trials with identical distractors in which the distractor is identified before the target. With simultaneous presentation and predictable target location, however, parallel processing of targets and distractors was possible that gave rise to an FCE in recognition accuracy. Analyses of false alarm rates revealed no evidence of significant response biases. 相似文献

A perceived action can be understood only when information about the action carried out and the objects used are taken into account. It was investigated how spatial and functional information contributes to establishing these relations. Participants observed static frames showing a hand wielding an instrument and a potential target object of the action. The 2 elements could either match or mismatch, spatially or functionally. Participants were required to judge only 1 of the 2 relations while ignoring the other. Both irrelevant spatial and functional mismatches affected judgments of the relevant relation. Moreover, the functional relation provided a context for the judgment of the spatial relation but not vice versa. The results are discussed in respect to recent accounts of action understanding. 相似文献

Low sensitivity to amplitude modulated (AM) sounds is reported to be associated with dyslexia. An important aspect of amplitude modulation cycles are the rise and fall times within the sound. In this study, simplified stimuli equivalent to just one cycle were used and sensitivity to varying rise times was explored. Adult participants with dyslexia or compensated dyslexia and a control group performed a detection task with sound pairs of different rise times. Results showed that the participants with dyslexia differed from the control group in rise time detection and a correlation was found between rise time detection and reading and phonological skills. A subgroup of participants with lower sensitivity to rise time detection characterized by low accuracy in syllable-level phonological skills was found within the dyslexic group. Short stimuli containing only one rise time produced associations with phonological skills and reading, even in a language where the perception of rise time contrasts are not crucial for the signaling of phonemic contrast. 相似文献

The present study examined changes in timing at the transition from synchronization to continuation tapping and the role played by knowledge of the transition. Three experiments employed a pseudo-synchronization paradigm: At the transition, the pacing tones were replaced by identical feedback tones. In Experiment 1, participants were not informed when the transition would occur. Immediately following the transition, an acceleration of tapping was observed. In Experiment 2, participants were informed about the exact position of the transition, which was in addition marked by a pitch change. Nonetheless, the same acceleration occurred. Experiment 3 dissociated the actual from the expected position of the transition, without changing the results. In addition, the delay of the feedback tones was manipulated and was found to affect the rate of tapping in the continuation phase. A single delayed tone at the transition had no lasting effect, however. The results are interpreted in light of the synchronization-continuation model of Vorberg and Wing [Vorberg, D., & Wing, A. (1996). Modelling variability and dependence in timing. In H. Heuer, & S. W. Keele (Eds.), Handbook of perception and action, Vol. 2 (pp. 181-262). San Diego: Academic Press], with the added assumption that the synchronization tapping strategy is maintained in the continuation phase. 相似文献

The soleus is the most commonly used muscle for H-reflex studies in humans, while limited comparable data have been produced from the gastrocnemii muscles. This article reviews the fundamental differences between the structure and function of the human soleus and gastrocnemii muscles, including recent data published about their complex innervation zones. Protocols for eliciting, recording, and assessing the H-reflex and M-wave magnitude in the human triceps surae are also discussed. 相似文献

The aim of this study was to examine the masculinity and femininity scales of Bem Sex Role Inventory (BSRI) among Turkish university students. Five hundred thirty-six students (280 men and 256 women) volunteered to complete the short-form of the BSRI and answer demographic questions. In factor analyses, the original factor structure (Bem, 1981) was found both in the mens and womens data. Comparisons of the factor structures with target rotation (Procrustes rotation) and comparison indexes showed no difference between the factor structures found among men and women. The internal consistency of the masculinity and femininity scales was acceptable, and t-tests showed that women scored higher on the femininity scale, and men scored higher on the masculinity scale. There were significant differences between men and women only on two masculinity items, but significant differences were found in 8 (of 10) femininity items. 相似文献

The present study aimed to investigate the determinants of stress-related growth. For this aim the associations of gender,
stressfulness of the event, and three coping strategies (problem-oriented, fatalistic, and helplessness) with stress-related
growth were tested by multiple regression analysis. Participants were 132 undergraduate students. Results revealed that females
reported higher levels of stress-related growth than males, and as expected, higher levels of the stressfulness of the event
associated with more stress-related growth. Furthermore, frequent utilization of problem-oriented and fatalistic coping strategies
was associated with higher stress-related growth. These findings were discussed in the light of relevant literature and culture-specific
features.

In order to generalize the dimensional structure of personality-relatively independent groups of covarying traits-across languages and cultures, a large number of cultures must be studied. Until recently only a few worldwide personality datasets have been available. The first large-scale studies indicate that the pattern of covariation between personality traits is universal and is relatively easily generalizable across languages and cultures. In contrast to the structure of personality, the comparison of the mean trait scores across cultures is much more problematic because cross-cultural differences turned out to be very small in their magnitude, about one-third of the magnitude of individual differences within culture. More integral (e.g., the similarity between personality profiles) or subtle (e.g., the disparity between positively and negatively worded items) measures can reveal more systematic relationships with relevant socioeconomic and geographic variables than the mean scores themselves. Relatively modest sizes of cross-cultural differences in the mean values may imply that a reasonable scalar equivalence can be achieved, and all individuals, irrespective of their language and culture, can be represented in a common metric. 相似文献
