ObjectivesDespite considerable scholarly attention over the last two decades, little is known about the influence of dispositional attributes on flow in sport. In achievement settings, mental toughness (MT) is a personal capacity supporting the process of high performance. Based on common overlaps with peak performance, confidence, control, concentration, and thriving in demanding situations, the present research aimed to explore the relationship between MT and dispositional flow and elucidate the psychological variables underlying dispositional flow.DesignA mixed method explanatory participant-selection design was adopted, whereby a quantitative approach was used to identify individuals for a qualitative follow-up phase to explore the relationship between MT and dispositional flow.MethodAn intensity sampling strategy was used to identify individuals with higher/lower MT and dispositional flow. Semi-structured interviews were conducted with 16 athletes (M age = 25, SD = 3.24; female n = 10; male n = 6). An inductive content analysis was undertaken to interpret data.ResultsSeven general dimensions describing the psychological attributes related to dispositional flow in athletes with higher and lower MT emerged. Specifically, differences in confidence, perfectionism, goal orientation, coping mechanism selection, locus of control, optimism and concentration were apparent and could account for differences in dispositional flow.ConclusionWhile all athletes experienced flow, there were differences in dispositional flow and the processes involved in entering, maintaining and restoring flow between higher and lower MT subgroups. Findings are discussed in relation to the existing literature, and recommendations for future research into the MT-flow relationship are outlined. 相似文献

Differential bundle functioning (DBF) analyses were conducted to determine whether seventh and eighth grade second language learners (SLLs) had lower probabilities of answering bundles of math word problems correctly that had heavy language demands, when compared to non-SLLs of equal math proficiency. Math word problems on each of four test forms (two at Grade 7 and two at Grade 8) were bundled together if they used the passive voice, conditional clause, relative clause, or a combination of any two. The results showed that the average total scores for SLLs was significantly lower than that for non-SLLs on each test form. However, only two bundles (passive voice and conditional clause at Grade 7 on Form 2) indicated statistically significant DBF against SLLs in favor of matched non-SLLs. An additional step was taken to determine whether the two bundles that showed statistically significant DBF against SLLs had biased the mean total scores for this group.The Walker, Zhang, Banks, and Cappaert (2012) procedure established for this purpose showed that this was not the case. Implications of the results are provided as well as suggestions for future research. 相似文献

A recent study showed that specific linguistic and grammatical features of a technique commonly referred to as statement analysis are applicable across different language groups. One limitation of that study was that it used an eyewitness crime video paradigm, which might be different from writing a statement after committing an actual criminal act. We remedied that limitation by using a mock crime paradigm. In this study, three language groups (English, Spanish, and Chinese) produced statements after committing a mock crime, taking a check, in an experimental context. Certain linguistic features significantly discriminated truths from lies similarly across the different language groups, suggesting that statement analysis might be applicable as a reliable indicator of deception across languages.

The capacity to remain spatially oriented is an essential function in our day to day lives and it seems that the form in which we acquire the spatial information affects the way in which the spatial knowledge is represented in our memory. The goal of this research was to investigate whether the acquisition of spatial information through the learning of three routes within an immersive environment was improved or impaired when participants have access to the backward perspective in addition to the forward perspective. Results, both in reproduction and drawing tasks, showed a poorer performance of the bidirectional group maybe due to the extra-effort involved in updating the spatial information trial by trial. However it seems that the experience enhanced the performance of the bidirectional group in one respect, as they were able to reduce significantly the number of error directions in the last path. 相似文献

There is a growing body of qualitative literature describing the lived experiences of people with tic disorders (TDs). The aim of this paper was to conduct a systematic review of this literature, synthesizing the perspectives of individuals on their experiences. Meta‐synthesis methodology was utilized to review and draw together findings from 10 articles, from which key concepts were extracted, and over‐arching themes generated. Six themes were identified to encompass the experience of TDs, including (1) cultural, semantic issues of the condition; (2) negative experiences in organizations and treatment; (3) the value and negative impact on interpersonal relationships; (4) personal identity in the constant presence of TDs; (5) concerns for the future; and (6) strategies to control and manage the observable presence of tics. Adaptive coping strategies were found to encompass continuous social adaptation, strategies to manage tics and social perceptions, self‐acceptance, advocacy, and support from others. The results highlighted the significant role of social and cultural issues related to understanding and stigma, which underpinned many of the lived experiences. Implications for clinical practice in supporting individuals with TDs were also highlighted. 相似文献

We present the results from a three-day artificial language learning study on adults. The study examined whether sentence-parsing limitations, in particular, difficulties revising initial syntactic/semantic commitments during comprehension, shape learners’ ability to acquire a language. Findings show that both comprehension and production of morphology pertaining to sentence argument structure are delayed when this morphology consistently appears at the end, rather than at the beginning, of sentences in otherwise identical grammatical systems. This suggests that real-time processing constraints impact acquisition; morphological cues that tend to guide linguistic analyses are easier to learn than cues that revise these analyses. Parallel performance in production and comprehension indicates that parsing constraints affect grammatical acquisition, not just real-time commitments. Properties of the linguistic system (e.g., ordering of cues within a sentence) interact with the properties of the cognitive system (cognitive control and conflict-resolution abilities) and together affect language acquisition. 相似文献

This article considers how Ernest Gellner used sociology and anthropology to attack ordinary language philosophy in Words and Things. It argues that this attack can be seen as a part of the movement to make philosophy more empirical or “naturalized,” something that has not been generally noted. It also discusses what general lessons to draw from Words and Things regarding how empirical knowledge should be used in philosophy. Among other things, the article argues that one important lesson is that empirical philosophers should make more use of “soft” social sciences, such as sociology and anthropology, and not focus exclusively on “harder” disciplines, such as physics and experimental psychology. Another upshot of the discussion is that philosophers should draw on empirical knowledge not only when they solve problems but also when they formulate them. 相似文献
