Despite long-standing assumptions that a sense of purpose in life and goal pursuit are mutually supportive, empirical evidence of their reciprocity remains deficient. In the context of a unique out-of-school time program that empowers youth to pursue passions through self-driven learning, we examined whether purpose and one aspect of goal pursuit—perceptions of goal progress—work together to sustain themselves and each other over time. 相似文献

IntroductionColor constancy, a property of conscious color experience, maintains object color appearance across illuminant changes. We investigated the neural correlates of subliminal vs. conscious stimulus deviations of color constancy manipulations.MethodsBehavioral and Oddball EEG/ERP experiments were conducted (n = 20). Psychophysical illuminant variation discrimination thresholds were first estimated, to establish individual perceptual awareness ranges, allowing for simulation of natural daylight spectral and spatial variations on colored surfaces, at different ambiguity levels.ResultsBehavioral results validated illuminant choice. ERPs showed a significant modulation of posterior P1 component specifically for the subliminal global uniform deviation condition, respecting color constancy. Neural correlates of conscious percepts were identified at posterior N2-P3 latencies, parietal (P3b) and frontal regions.ConclusionsWe identified an early subliminal correlate of low-level illuminant change, which reflects automatic unconscious detection of global color constancy deviations. Its suppression under conscious perception is probably due to top-down suppression according to prediction error models. 相似文献

This research explores the degree of acceptability of the reasons given by a team leader to explain the unfair sanctions he/she distributes to his/her subordinates. Fifteen male high level managers leading team leaders, and 61 employees (30 women and 31 men) responded to a questionnaire in which they had to assess the desirability of the reasons given by a team leader for which he/she unfairly punished his subordinates: it might be either getting angry with them despite their good work (negative sanction) or, on the contrary, refraining intervention when they made mistakes (positive sanction). The results indicate a disaccountability of both the receiver and the distributor of the sanction, with, instead, the highlighting of contextual determinants, especially in case of negative sanction. There is also an influence of the direction of the sanction (positive vs. negative) on the stable/unstable component of the instance chosen as explanatory. These results are discussed on a theoretical level and perspectives of applications are proposed. 相似文献

This study is the first systematic effort to investigate psychological services provided to relatives of ICU patients at Nicosia General Hospital. Documentation of psychological sessions provided to relatives of ICU patients for the years 2011–2014 was analyzed. To investigate possible differences in the total number of sessions for the referenced years, the records were analyzed using patients’ demographics, the outcome of hospitalization and the total number of sessions with relatives. A questionnaire was sent to the ICU staff aiming to identify their perception towards the need for psychological support. A total number of 863 psychological sessions were conducted with 640 relatives of 345 patients hospitalized in the ICU. Results indicate that more sessions are recorded when the outcome of younger patients’ condition worsens, whereas the number of sessions decreases for older patients’ families. When comparing the personnel’s beliefs, regarding the importance of providing psychological services to different age groups, significant difference was found suggesting that the older the patient the less sessions they believe are required indicating a possible ageism bias. 相似文献

Shannon entropy is being increasingly used in biomedical research as an index of complexity and information content in sequences of symbols, e.g. languages, amino acid sequences, DNA methylation patterns and animal vocalizations. Yet, distributional properties of information entropy as a random variable have seldom been the object of study, leading to researchers mainly using linear models or simulation-based analytical approach to assess differences in information content, when entropy is measured repeatedly in different experimental conditions. Here a method to perform inference on entropy in such conditions is proposed. Building on results coming from studies in the field of Bayesian entropy estimation, a symmetric Dirichlet-multinomial regression model, able to deal efficiently with the issue of mean entropy estimation, is formulated. Through a simulation study the model is shown to outperform linear modeling in a vast range of scenarios and to have promising statistical properties. As a practical example, the method is applied to a data set coming from a real experiment on animal communication. 相似文献

Attachment theory proposes that experiences of acceptance and rejection will modify feelings of attachment security, but such processes have rarely been investigated. In this study, daily variations in attachment anxiety and avoidance were investigated across 7 days in a sample of college undergraduates currently in romantic relationships. We observed significant within-person variation in attachment avoidance and anxiety. Participants reported lower anxiety and avoidance on days on which they felt more accepted by their romantic partners. Further, perceptions of acceptance predicted the following day’s attachment security through lower negative mood. Greater variability in attachment avoidance and anxiety was associated with greater physical aggression in relationships. 相似文献

Aggregate temperament scores were calculated across 17 studies for 18 countries. These scores were analyzed in relation to aggregate personality scores, cultural orientation, and allelic distribution reported in prior studies. Cross-culture patterns were largely consistent with those previously reported for personality: countries high on Surgency (SUR) were high on Extraversion, high Negative Affectivity (NEG) was consistent with Neuroticism, and Regulatory Capacity (RC) with Agreeableness. Regarding cultural orientation, aggregate SUR was associated with low Power Distance and Long-Term Orientation; NEG with low Individualism and high Masculinity and Uncertainty Avoidance; and RC with low Power Distance and Masculinity. Higher proportion of MAOA-uVNTR low expression alleles was associated with low SUR and low RC; and A118G G-form allele proportion with low RC. 相似文献

Statistical inference (including interval estimation and model selection) is increasingly used in the analysis of behavioral data. As with many other fields, statistical approaches for these analyses traditionally use classical (i.e., frequentist) methods. Interpreting classical intervals and p‐values correctly can be burdensome and counterintuitive. By contrast, Bayesian methods treat data, parameters, and hypotheses as random quantities and use rules of conditional probability to produce direct probabilistic statements about models and parameters given observed study data. In this work, we reanalyze two data sets using Bayesian procedures. We precede the analyses with an overview of the Bayesian paradigm. The first study reanalyzes data from a recent study of controls, heavy smokers, and individuals with alcohol and/or cocaine substance use disorder, and focuses on Bayesian hypothesis testing for covariates and interval estimation for discounting rates among various substance use disorder profiles. The second example analyzes hypothetical environmental delay‐discounting data. This example focuses on using historical data to establish prior distributions for parameters while allowing subjective expert opinion to govern the prior distribution on model preference. We review the subjective nature of specifying Bayesian prior distributions but also review established methods to standardize the generation of priors and remove subjective influence while still taking advantage of the interpretive advantages of Bayesian analyses. We present the Bayesian approach as an alternative paradigm for statistical inference and discuss its strengths and weaknesses. 相似文献

Intelligent Assistive Systems (IASs) provide personalised support to individuals to increase their autonomy and competence in performing activities. The personalisation of such technology represents a particular challenge, for the individuals abilities typically change over time. The aim of this research was to explore a theory-based, activity-centred framework for the development of IASs that both facilitate the active involvement of caregivers and target users and allow for adaptation to the individual over time.Medication management was focused on as a case study. Three older adults and two caregivers were involved in a co-design process of an IAS prototype system, the MED-AR, which uses projection-based augmented reality as the user interface technology. The theoretical framework for the design and evaluation of the MED-AR was activity theory. For the decision-making process of the MED-AR, formal argumentation theory was used. The major contributions of the study are (i) a formal framework for understanding the level of independence in activities and the way an IAS can tailor support to an individual and a situation, including caregivers; and (ii) a model for involving older adults and caregivers in a co-design process in the first phases of developing IASs. 相似文献
