There is an increasing trend towards assessing the scientific performance of researchers and institutions of higher learning
in the form of journal publications and the associated citations. Currently, the journal impact factor (JIF) value is the
most widely used measure for any academic contents. However, there are growing concerns for the unethical practices adopted
by journal editors to manipulate the JIF computations. Recently, a Swiss journal, Folia Phoniatrica et Logopaedica which has
a JIF value of 0.655 in the year 2006 registers a remarkable JIF increment (of 119%) to 1.439 in the year 2007. It is believed
that the journal can achieve such a prominent JIF improvement by publishing a single editorial article that self-cited 66
of its own articles published either in the year 2005 or 2006. The journal has been revoked of any JIF value in the following
year of 2008. Thus, it is interesting to review the possible alternative bibliographical trend for the journal should the
self-cite event has been avoided, the circumstances leading to the decision by the editor to publish such an article and the
possible ethical implications or lessons that can be derived from this incident. 相似文献

Digraphs are graphemes that are composed of two letters like the "ou" in "soup". We hypothesized that the serial-reading strategy of dyslexic readers might interfere with the processing of digraphs. We used a letter-detection task to compare the processing of vowel digraphs in dyslexic and typical-reading children. Both groups were found to be slower in detecting a letter within a vowel digraph than in detecting a letter of a single-letter grapheme. The slower response to target letters embedded in a digraph was position independent in both groups. We also found that dyslexic children did not differ from typical-reading children in the detection of letters in words. These results indicate that typical-reading and dyslexic children process vowel digraphs as perceptual units and that dyslexic children do not show impairments in this early visual process. 相似文献

To explain fear of blushing, it has been proposed that individuals with fear of blushing overestimate the social costs of
their blushing. Current information-processing models emphasize the relevance of differentiating between more automatic and
more explicit cognitions, as both types of cognitions may independently influence behavior. The present study tested whether
individuals with fear of blushing expect blushing to have more negative social consequences than controls, both on an explicit
level and on a more automatic level. Automatic associations between blushing and social costs were assessed in a treatment-seeking
sample of individuals with fear of blushing who met DSM-IV criteria for social anxiety disorder (n = 49) and a non-anxious control group (n = 27) using a single-target Implicit Association Test (stIAT). In addition, participants’ explicit expectations about the
social costs of their blushing were assessed. Individuals with fear of blushing showed stronger associations between blushing
and negative outcomes, as indicated by both stIAT and self-report. The findings support the view that automatic and explicit
associations between blushing and social costs may both help to enhance our understanding of the cognitive processes that
underlie fear of blushing. 相似文献

Previous studies have shown the appearance of right-sided language-related brain activity in right-handed patients after a stroke. Non-invasive brain stimulation such as transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) have been shown to modulate excitability in the brain. Moreover, rTMS and tDCS have been found to improve naming in non-fluent post-stroke aphasic patients. Here, we investigated the effect of tDCS on the comprehension of aphasic patients with subacute stroke. We hypothesized that tDCS applied to the left superior temporal gyrus (Wernicke’s area) or the right Wernicke’s area might be associated with recovery of comprehension ability in aphasic patients with subacute stroke. Participants included right-handed subacute stroke patients with global aphasia due to ischemic infarct of the left M1 or M2 middle cerebral artery. Patients were randomly divided into three groups: patients who received anodal tDCS applied to the left superior temporal gyrus, patients who received cathodal tDCS applied to the right superior temporal gyrus, and patients who received sham tDCS. All patients received conventional speech and language therapy during each period of tDCS application. The Korean-Western Aphasia Battery (K-WAB) was used to assess all patients before and after tDCS sessions. After intervention, all patients had significant improvements in aphasia quotients, spontaneous speech, and auditory verbal comprehension. However, auditory verbal comprehension improved significantly more in patients treated with a cathode, as compared to patients in the other groups. These results are consistent with the role of Wernicke’s area in language comprehension and the therapeutic effect that cathodal tDCS has on aphasia patients with subacute stroke, suggesting that tDCS may be an adjuvant treatment approach for aphasia rehabilitation therapy in patients in an early stage of stroke. 相似文献

The striatum is associated with the learning and retention of motor skills. Several studies have shown that motor learning induces neuronal changes in the striatum. We investigated whether macroscopic change in striatum volume occurs in a segment of the human population who learned basketball-related motor skills and practiced them throughout their entire athletic life. Three-dimensional magnetic resonance imaging volumetry was performed in basketball players and healthy controls, and striatum volumes were compared based on basketball proficiency, region and side. We identified morphological enlargement in the striatum of basketball players in comparison with controls. Our results suggest that continued practice and repetitive performance of basketball-related motor skills may induce plastic structural changes in the human striatum. 相似文献

It is argued that John Bickle’s Ruthless Reductionism is flawed as an account of the practice of neuroscience. Examples from genetics and linguistics suggest, first, that not every mind-brain link or gene-phenotype link qualifies as a reduction or as a complete explanation, and, second, that the higher (psychological) level of analysis is not likely to disappear as neuroscience progresses. The most plausible picture of the evolving sciences of the mind-brain seems a patchwork of multiple connections and partial explanations, linking anatomy, mechanisms and functions across different domains, levels, and grain sizes. Bickle’s claim that only the molecular level provides genuine explanations, and higher level concepts are just heuristics that will soon be redundant, is thus rejected. In addition, it is argued that Bickle’s recasting of philosophy of science as metascience explicating empirical practices, ignores an essential role for philosophy in reflecting upon criteria for reduction and explanation. Many interesting and complex issues remain to be investigated for the philosophy of science, and in particular the nature of interlevel links found in empirical research requires sophisticated philosophical analysis. 相似文献

A cross-sectional study was conducted with 605 practitioners of Brazilian Jiu Jitsu (BJJ) to test the hypothesis that high arousal rituals promote social cohesion, primarily through identity fusion. BJJ promotion rituals are rare, highly emotional ritual events that often feature gruelling belt-whipping gauntlets. We used the variation in such experiences to examine whether more gruelling rituals were associated with identity fusion and pro-group behaviour. We found no differences between those who had undergone belt-whipping and those who had not and no evidence of a correlation between pain and social cohesion. However, across the full sample we found that positive, but not negative, affective experiences of promotional rituals were associated with identity fusion and that this mediated pro-group action. These findings provide new evidence concerning the social functions of collective rituals and highlight the importance of addressing the potentially diverging subjective experiences of painful rituals. 相似文献

It is currently unclear whether it is the need to maintain metabolic efficiency, the need to keep skeletal loading below critical force levels, or simple mechanical factors that drive the walk-to-run (W-R) and run-to-walk (R-W) transitions in human gait. Eighteen adults (9 males and 9 females) locomoted on an instrumented treadmill using their preferred gait. Each completed 2 ascending (W-R) and 2 descending (R-W) series of trials under three levels of loading (0%, 15% and 30% body weight). For each trial, participants locomoted for 60 s at each of 9 different speeds--4 speeds both above and below their preferred transition speed (PTS) plus their PTS. Evidence was sought for critical levels of key kinetic (maximum vertical force, impulse, first peak force, time to first peak force and maximum loading rate), energetic (oxygen consumption, transport cost) and mechanical variables (limb lengths, strength) predictive of the gait transition. Analyses suggested the kinetic variables of time to first peak force and loading rate as the most likely determinants of the W-R and R-W transitions. 相似文献

Implicit self-esteem and social anxiety: differential self-favouring effects in high and low anxious individuals 总被引:8,自引:0,他引:8
de Jong PJ 《Behaviour research and therapy》2002,40(5):501-508
This study was designed to investigate the role of negative self-image in social phobia. Participants were 19 high and 19 low socially anxious women. Because self-report measures of self-esteem are sensitive to self-presentation and impression management strategies, an implicit association test (IAT) was used to assess participants' self-esteem as well as their general evaluation of others ('other-esteem'). Socially anxious women displayed relatively low levels of self-esteem on self-report measures. However, at the implicit level, low and high anxious women were characterised by a similar, highly positive self-image. Both groups displayed a relatively low 'other-esteem'. Yet, this self-favouring effect was considerably weaker in high than in low anxious participants. The results provide no unequivocal support for the idea that low self-esteem plays an important role in social anxiety. Yet, rather than by low self-esteem per se, socially anxious people are characterised by a small discrepancy between esteem of self and others, and it may be this reduced tendency to self-favouring that is pivotal to social anxiety. 相似文献

The non-associative account of phobic etiology assumes that a number of specific fears (e.g., fear of heights, water, spiders, strangers, and separation) have an evolutionary background and may occur in the absence of learning experiences (e.g., conditioning). By this view, these specific fears pertain to stimuli that once posed a challenge to the survival of our prehistoric ancestors. Accordingly, they would emerge spontaneously during the course of normal development and only in a minority of individuals, these specific fears would persist into adulthood. While the non-associative approach has generated interesting findings, several critical points can be raised. First, it capitalizes on negative findings, i.e., the failure to document learning experiences (e.g., conditioning, modeling) in the history of phobic children. Second, it largely ignores factors that have been found to be crucial for the acquisition of early childhood fears (e.g., the developmental level of the child, stimulus characteristics such as novelty, aversiveness, and unpredictability, and early experience with uncontrollable events). As an alternative to the non-associative account, we briefly describe a multifactorial model of childhood fears and phobias. 相似文献
