Languages such as Swedish use suprasegmental information such as tone, over and above segments, to mark lexical contrast. Theories differ with respect to the abstractness and specification of tone in the mental lexicon. In a forced choice task, we tested Swedish listeners’ responses to words with segmentally identical first syllables differing in tonal contours (characterized as Accents 1 and 2). We assumed Accent 1 to be lexically specified for a subset of words and hypothesized that this specification would speed up word accent identification. As was predicted, listeners were fastest in choosing the tonally correct word when the accent was lexically specified. We conclude that the processing of surface tonal contours is governed by their underlying lexical structure with tonal specification. 相似文献

Fear conditioning studies have shown that social anxiety is associated with enhanced expectancy of aversive outcome. However, the relation between cognitive expectancy and social anxiety has never been tested in avoidance conditioning paradigms. We compared 48 low (LSA) and high socially anxious individuals (HSA) on subjective expectancy of aversive outcome during an avoidance conditioning task. Displays of neutral faces were coupled with an aversive outcome (US): a shout and a shock. Participants could avoid the US by pressing a correct button from a button box. First, HSA showed higher US expectancy than LSA during the initial phase of avoidance conditioning, supporting the view that socially anxious individuals have an expectancy bias when social situations are ambiguous. Second, when the avoidance response became unavailable, LSA showed lower US expectancy than HSA, suggesting that low socially anxious individuals are prone to a positive bias when perceived threat is high. A lack of such positive bias in socially anxious individuals may lead to higher susceptibility to safety behavior interpretations. Together, these findings support the role of cognitive processes in avoidance conditioning and underscore the relevance to encounter avoidance learning when studying social anxiety. 相似文献

The main aim of this paper is to highlight the need to address the conceptual problem of ‘implicit knowledge’ or ‘implicit cognition’ — a notion especially important in the study of the nonverbal minds of animals and infants. We review some uses of the term ‘implicit’ in psychology and allied disciplines, and conclude that conceptual clarification of this notion is not only lacking, but largely avoided and reduced to a methodological problem. We propose that this elusive notion is central in the study not only of animal and infant minds, but also the human adult mind. Some promising approaches in developmental and evolutionary psychology towards innovative conceptualization of implicit knowledge remain conceptually underdeveloped and in need of reconsideration and re-elaboration. We conclude by suggesting that the challenge of implicit cognition and nonverbal minds will only be solved through a concerted interdisciplinary approach between psychology and other disciplines. 相似文献

A validation of eye movements as a measure of elementary school children's developing number sense 总被引:1,自引:0,他引:1

The number line estimation task captures central aspects of children's developing number sense, that is, their intuitions for numbers and their interrelations. Previous research used children's answer patterns and verbal reports as evidence of how they solve this task. In the present study we investigated to what extent eye movements recorded during task solution reflect children's use of the number line. By means of a cross-sectional design with 66 children from Grades 1, 2, and 3, we show that eye-tracking data (a) reflect grade-related increase in estimation competence, (b) are correlated with the accuracy of manual answers, (c) relate, in Grade 2, to children's addition competence, (d) are systematically distributed over the number line, and (e) replicate previous findings concerning children's use of counting strategies and orientation-point strategies. These findings demonstrate the validity and utility of eye-tracking data for investigating children's developing number sense and estimation competence. 相似文献

Previous studies of the perceptual processing and dynamics of emotional expression in faces have been limited by the lack of realistic yet controlled stimuli. The present work offers researchers a method for creating such stimuli for exploring these phenomena. We describe the creation of the stimuli and a series of experiments testing the validity of these stimuli with respect to emotional expressions in humans. Participants evaluated synthesized facial images and standardized photographs of six basic emotional expressions for intensity and accuracy of perceived emotion. Comparisons of these measures were qualitatively similar for synthesized and photographed faces. A manipulation of the magnitude of the synthesized expressions yielded a significant effect on the perceived intensity of expression. In a subsequent multidimensional scaling study, no systematic differences were uncovered in the derived configurations of the synthesized expressions and the photographs. These results are discussed in the context of possible future research applications. 相似文献

Several studies indicate that executive functions (EF), such as working memory (WM), inhibition or flexibility can be improved by training and that these training‐related benefits in WM capacity generalize to reading and mathematical abilities. However, the results of these studies are inconsistent and most of them focused on WM training in children with learning difficulties. Evidence for typically developing children is rare and no study has investigated inhibition training or flexibility training. There is also a lack of studies taking motivational factors into account. Therefore, this study compared the effects of game‐based and standard training regimens targeting WM, inhibition, or flexibility in children. One hundred and fifty‐three typically developing elementary school students (mean age = 9.6 years, standard deviations = 0.8) were investigated in an intervention design with a pretest, 21 sessions of training, a posttest and a follow‐up after three months. They were randomized into one of six training groups or a control group. We found training gains in all training groups and higher self‐reported motivation in the game‐based as compared to the standard training groups. Furthermore, there was domain‐specific transfer to untrained EF tasks across all training groups. We found greater performance improvements in reading ability (but not mathematics) in the game‐based flexibility training group and the game‐based inhibition training group as compared to the control group. Transfer effects were still significant at follow‐up. In sum, our findings provide first evidence for a systematic comparison of training on different domains of EF and their differential effects on academic abilities. 相似文献

There is a view that faces and objects are processed by different brain mechanisms. Different factors may modulate the extent to which face mechanisms are used for objects. To distinguish these factors, we present a new parametric multipart three-dimensional object set that provides researchers with a rich degree of control of important features for visual recognition such as individual parts and the spatial configuration of those parts. All other properties being equal, we demonstrate that perceived facelikeness in terms of spatial configuration facilitated performance at matching individual exemplars of the new object set across viewpoint changes (Experiment 1). Importantly, facelikeness did not affect perceptual discriminability (Experiment 2) or similarity (Experiment 3). Our findings suggest that perceptual resemblance to faces based on spatial configuration of parts is important for visual recognition even after equating physical and perceptual similarity. Furthermore, the large parametrically controlled object set and the standardized procedures to generate additional exemplars will provide the research community with invaluable tools to further understand visual recognition and visual learning. 相似文献

Previous research has shown that forensic psychiatric treatment reduces reoffending, rehospitalization and premature mortality. Treatment outcome varies with diagnosis, but little is known about the influence of sex, psychosocial adjustment and aftercare. To assess these variables, we interviewed male and female patients discharged from three psychiatric security hospitals in Germany in the years 2010–2017. Participants were interviewed at discharge (n = 609) and 1 year later (n = 366) about reoffending, readmissions, substance use and psychosocial adjustment. Among patients with substance use disorder (SUD), 14% reoffended, 20% were re-hospitalized and 60% maintained abstinence. Among patients with severe mental disorder, 5% reoffended and 13% were re-hospitalized. Significant sex differences were found in offenders with SUD. The results suggest that sociodemographic and disorder-related risk factors are associated with treatment success and that female patients with SUD might need a specific treatment approach. Sex-specific aspects, diagnosis and psychosocial adjustment should be considered in forensic psychiatric treatment and risk assessment. 相似文献
