This paper introduces key concepts for studying intraindividual variability in narratives (narrative IIV). Narrative IIV is conceptualized in terms of sources of within-person variation (events and audiences) and dimensions of variation (structural and motivational/affective dimensions of narratives). Possible implications of narrative IIV for well-being and self and social development are outlined. Considering narrative IIV leads to complexity in both theory and method, raising the issue of whether some avenues might be more productive than others. Using previously collected data, we sought to evaluate the research potential of different indices of narrative IIV (n = 106 participants; n = 1272 narratives). All analyses were preregistered: doi: 10.17605/OSF.IO/SXV4W . Findings show that narrative IIV is distinct depending on source and dimension, replicating previous work. However, narrative IIV was largely unrelated to the measures of well-being and self and social development used in the present study. These findings support the practice of aggregating across narratives in existing research, at least for these outcomes and sources of variation, and provide important guidance for investigators who remain interested in the possible insights that narrative IIV may reveal about the person. © 2020 European Association of Personality Psychology  相似文献

Although individuals with autism spectrum disorder (ASD) tend to behave repetitively, certain reinforcement contingencies (e.g., lag schedules) can be used to increase behavioral variability. In a lag schedule, reinforcers only follow responses that differ from recent responses. The present study was designed to promote variable play behavior in preschoolers with ASD interacting with playsets and figurines and to assess preference for variability and repetition contingencies. Data have shown a preference for variability in pigeons and college students, but this effect has not been explored in clinical populations. In this experiment, preschoolers with ASD were taught to discriminate between variability and repetition contingencies. Only play behaviors that met a lag schedule were reinforced in the presence of one color, and only repetitive behaviors were reinforced in the presence of another. After differential performance was established, participants experienced a concurrent chains schedule. Participants chose between the colors taught in training and then completed a play session with the selected contingency. One participant selected variability and repetition equally. The other participants showed a slight preference for variability. These results indicate that some individuals with ASD may play repetitively, not because they prefer repetition, but because they require additional teaching to play variably.  相似文献

Despite a considerable rationale for a relationship between executive functions (EFs) and resting heart rate variability based on the neurovisceral integration model, meta-analyses reveal relatively small effect sizes. This study aims to evaluate this relationship in three EF tasks by taking task characteristics and implicit affect and attention regulation measured by action-state orientation into account. Analyzing 154 participants (M = 23.56 years; SD = 3.14) indicated that the relationship was moderated by action-state orientation. However, the Johnson-Neyman test only found a relationship for state-oriented individuals, which also differed in the direction between demanding and low-demanding tasks. Therefore, this study cannot fully confirm the neurovisceral integration model. Implications for future research are discussed.  相似文献

Life-satisfaction judgments are ubiquitously used as indicators of wellbeing. The construct validity of these judgments relies heavily on self–informant agreement. However, agreement is necessary, but not sufficient to claim that life-satisfaction judgments are valid. In addition, self–informant agreement should be based on the use of valid information about satisfaction with important life domains. An alternative possibility is that agreement is based on impressions about personality traits. We tested these two hypotheses in a model that predicted self-ratings and informant ratings of life satisfaction from shared perceptions of personality and satisfaction with life domains. In a round-robin study of families, we found that life-domains were the key predictor of self–informant agreement. However, the Depressiveness facet of Neuroticism had a small direct effect. In addition, it was indirectly related to self–informant agreement because it predicts lower satisfaction in important life-domains that were used to form life-satisfaction judgments.  相似文献

Multisensory integration, the binding of sensory information from different sensory modalities, may contribute to perceptual symptomatology in schizophrenia, including hallucinations and aberrant speech perception. Differences in multisensory integration and temporal processing, an important component of multisensory integration, are consistently found in schizophrenia. Evidence is emerging that these differences extend across the schizophrenia spectrum, including individuals in the general population with higher schizotypal traits. In the current study, we investigated the relationship between schizotypal traits and perceptual functioning, using audiovisual speech-in-noise, McGurk, and ternary synchrony judgment tasks. We measured schizotypal traits using the Schizotypal Personality Questionnaire (SPQ), hypothesizing that higher scores on Unusual Perceptual Experiences and Odd Speech subscales would be associated with decreased multisensory integration, increased susceptibility to distracting auditory speech, and less precise temporal processing. Surprisingly, these measures were not associated with the predicted subscales, suggesting that these perceptual differences may not be present across the schizophrenia spectrum.  相似文献

Understanding how road environments stress bicyclists (and prospective bicyclists) has important implications for road design and network planning. With the rise of wearable bio-sensing technology, the potential for measuring real-time environmental acute stress is emerging. In this naturalistic cross-over field experiment, we investigate bicyclist stress through heart rate variability (HRV). We examine the relationship between HRV and the road environment through a series of multilevel statistical models. Results suggest that participants’ HRV are only certain to differ on one (the local road) of five road environments tested. The differences in participants’ HRV between two collectors and two arterials are far more tenuous. We discuss the validity of HRV and other biometrics for assessing stress and discuss how HRV and other biometrics might help improve our understanding of bicyclists’ perceptions of road environments.  相似文献

ABSTRACT

Perceptual fluency typically has a positive influence on aesthetic evaluations of beauty, but few studies have examined its influence on creativity evaluations. Creativity has two facets, originality and quality. If creativity judgments involve estimating product originality, such judgments may be associated with perceptual disfluency, while product quality may be associated with perceptual fluency. We examined the relationship between perceptual fluency and judgments of creativity and beauty across seven experiments. Creativity judgments were affected by most perceptual fluencysources. We observed a highly-fluent-is-beautiful-and-creative relation when testing repeated exposure and figure-ground contrast. Prototypicality displayed a high-fluency–is-beautiful relation, with creativity judgments unaffected. Visual complexity displayed a consistent disfluent-is-creative effect, with mixed results for beauty. For creativity (but not beauty) evaluations, increased saliency of visual complexity led to discounting fluent-is-creative effects, supporting the hypothesis that there are at least two fluency pathways to creativity judgments that take both originality and quality into account.  相似文献

Long-range autocorrelations (LRA) are a robust feature of rhythmic movements, which may provide important information about neural control and potentially constitute a powerful marker of dysfunction. A clear difficulty associated with the assessment of LRA is that it requires a large number of cycles to generate reliable results. Here we investigate how series length impacts the reliability of LRA assessment. A total of 94 time series extracted from walking or cycling tasks were re-assessed with series length varying from 64 to 512 data points. LRA were assessed using an approach combining the rescaled range analysis or the detrended fluctuation analysis (Hurst exponent, H), along with the shape of the power spectral density (α exponent). The statistical precision was defined as the ability to obtain estimates for H and α that are consistent with their theoretical relationship, irrespective of the series length. The sensitivity consisted of testing whether significant differences between experimental conditions found in the original studies when considering 512 data points persisted with shorter series. We also investigate the use of evenly-spaced diffusion plots as a methodological improvement of original version of methods for short series. Our results show that the reliable assessment of LRA requires 512 data points, or no shorter than 256 data points provided that more robust methods are considered such as the evenly-spaced algorithms. Such series can be reasonably obtained in clinical populations with moderate, or even more severe, gait impairments and open the perspective to extend the use of LRA assessment as a marker of gait stability applicable to a broad range of locomotor disorders.  相似文献
