From their finding that the substantial magnitude of the Stroop interference that occurs when a participant’s initial fixation is directed at the optimal viewing position is eliminated when the initial fixation is directed at the end of a word, Perret and Ducrot (2010) concluded that initial fixation at the latter position likely prevents reading. In the present study, we further examined this interpretation. To this end, the two conflict dimensions (semantic vs. response) that were confounded in the original work were separated within a semantically based Stroop paradigm (Neely & Kahan, 2001) that was administered with vocal (instead of manual) responses. In line with past findings showing greater interference in the vocal task, the reported results indicated that standard Stroop interference was reduced, but not eliminated, thus making the initial interpretation in terms of reading suppression unlikely. This conclusion is further strengthened by the presence of isolated semantic interference, the magnitude of which remained significant and was unaffected by viewing position. In sum, these results show that initial fixation of the end of a word simply reduces (nonsemantic) response competition. 相似文献
We report the results of a large-scale picture naming experiment in which we evaluated the potential contribution of nine theoretically relevant factors to naming latencies. The experiment included a large number of items and a large sample of participants. In order to make this experiment as similar as possible to classic picture naming experiments, participants were familiarized with the materials during a training session. Speeded naming latencies were determined by a software key on the basis of the digital recording of the responses. The effects of various variables on these latencies were assessed with multiple regression techniques, using a repeated measures design. The interpretation of the observed effects is discussed in relation to previous studies and current views on lexical access during speech production. 相似文献
In this article, we present a new lexical database for French:Lexique. In addition to classical word information such as gender, number, and grammatical category,Lexique includes a series of interesting new characteristics. First, word frequencies are based on two cues: a contemporary corpus
of texts and the number of Web pages containing the word. Second, the database is split into a graphemic table with all the
relevant frequencies, a table structured around lemmas (particularly interesting for the study of the inflectional family),
and a table about surface frequency cues. Third,Lexique is distributed under a GNU-like license, allowing people to contribute to it. Finally, a metasearch engine,Open Lexique, has been developed so that new databases can be added very easily to the existing ones.Lexique can either be downloaded or interrogated freely fromhttp://www.lexique.org. 相似文献
The different forms of religious unbelief are still much of an open question. Using data (N = 4,404) from three European countries—Finland, Denmark, and the Netherlands—we sought to identify underlying unbeliever groups among those with the strongest disbelief in God (N = 2,258). Latent class analyses were conducted on the nontheistic supernatural beliefs of this subsection of participants, resulting in the same three unbeliever groups in each country: analytic atheists, spiritual but not religious (SBNR), and uncertain nonbelievers. Next, we explored these groups on a variety of dimensions, especially on the group members’ attitudes to religion, certainty of beliefs, cognitive dispositions, and worldview. One-way analyses of variance (ANOVAs) revealed similarities as well as distinct characters for each of the latent groups. The groups differed most in intuitive thinking style, overmentalizing bias, and other ontological confusions. To compare the latent groups to all other individuals who took part in the study, two discriminant analyses were run with all participants. This resulted in four meaningful dimensions that supported and extended the ANOVAs findings and allowed for the consideration of other (non)believers. Overall, this study supports earlier findings on analytic atheists and SBNR while providing new information about their dispositions. Of interest, the uncertain nonbeliever group has been largely unexplored previously, and it should gain more attention in future studies. 相似文献
Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we present computational tests of the hypothesis that this early exposure to severely degraded auditory inputs serves an adaptive purpose—it may induce the neural development of extended temporal integration. Such integration can facilitate the detection of information carried by low-frequency variations in the auditory signal, including emotional or other prosodic content. To test this prediction, we characterized the impact of several training regimens, biomimetic and otherwise, on a computational model system trained and tested on the task of emotion recognition. We find that training with an auditory trajectory recapitulating that of a neurotypical infant in the pre-to-postnatal period results in temporally extended receptive field structures and yields the best subsequent accuracy and generalization performance on the task of emotion recognition. This strongly suggests that the progression from low-pass-filtered to full-frequency inputs is likely to be an adaptive feature of our development, conferring significant benefits to later auditory processing abilities relying on temporally extended analyses. Additionally, this finding can help explain some of the auditory impairments associated with preterm births, suggests guidelines for the design of auditory environments in neonatal care units, and points to enhanced training procedures for computational models. 相似文献
This study investigated the contribution of otolithic and somesthetic inputs in the perception of body orientation when pitching at very slow velocities. In Experiment 1, the subjects' task was to indicate their subjective postural vertical, in two different conditions of body restriction, starting from different angles of body tilt. In the "strapped" condition, subjects were attached onto a platform by means of large straps. In the "body cast" condition, subjects were completely immobilized in a depressurized system, which attenuates gravity-based somesthetic cues. Results showed that the condition of body restriction and the initial tilt largely influenced the subjective postural vertical. In Experiment 2, subjects were displaced from a vertical position and had to detect the direction of body tilts. Results showed that the threshold for the perception of body tilt was higher when subjects were immobilized in the body cast and when they were tilted backward. Experiment 3 replicated the same protocol from a supine starting position. Compared to results of Experiment 2, the threshold for the perception of body tilt decreased significantly. Overall, these data suggested that gravity-based somesthetic cues are more informative than otolithic cues for the perception of a quasi-static body orientation. 相似文献

Background: People differ in their ability to regulate their physiological stress response. Individual differences in emotion regulation strategies such as suppression and reappraisal may explain this differential response to stress.
Objective: The aim of the current study was to assess whether daily use of suppression and reappraisal as well as their interaction predicted physiological stress reactivity and/or recovery, as assessed by variations in cortisol levels.
Method: Thirty-eight healthy young adults (13 men) completed the Emotion Regulation Questionnaire and were exposed to a psychosocial stressor, throughout which salivary cortisol was measured.
Results: Linear regressions showed main effects of reappraisal and suppression on cortisol reactivity and a main effect of suppression on cortisol recovery, where both strategies were positively associated with stress phases. Moreover, results showed a significant interaction of suppression by reappraisal in predicting both cortisol reactivity and recovery. Simple slope tests revealed that reappraisal moderated the association between suppression and both phases of cortisol responsivity.
Conclusion: Our results suggest that reappraisal represents a protective factor against the deleterious effects of suppression on stress responsivity. This study underlines the importance of investigating emotion regulation strategies as a means to understand individual differences in vulnerability to stress-related psychopathologies such as anxiety and depression. 相似文献
