Despite the lack of invariance problem (the many-to-many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side-stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real-world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two-layer network that borrows one element from ASR, long short-term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human-like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR. 相似文献

Risk assessment tools driven by algorithms offer promising advantages in predicting the recidivism risk of defendants. Jurisdictions are increasingly relying upon risk tool outcomes to help judges at sentencing with their decisions on whether to incarcerate or whether to use community-based sanctions. Yet as sentencing has significant consequences for public safety and individual rights, care must be taken that the tools relied upon are appropriate for the task. Judges are encouraged to act as gatekeepers to evaluate whether the forensic risk assessment tool offered has a sufficient level of validity in that it is fit for the purposes of sentencing, provides an acceptable level of accuracy in its predictions, and achieves an adequate standard of reliability with regard to its outcomes. 相似文献

The purpose of this study was to explore the experience of performance slumps in cricket from the perspective of psychological resilience. Findings from a thematic analysis of a focus group (n?=?4 athletes) and one-to-one interviews (n?=?10 athletes) with 14 expert cricket batsmen indicated that numerous factors associated with psychological resilience protected players experiencing poor performance from the negative effects of stress, enabling them to successfully implement strategies to overcome slumps. These strategies fostered the strengthening and acquisition of technical, tactical, and psychosocial resources that protected players against future slumps. The findings suggest practical strategies to aid players experiencing slumps to overcome their performance difficulties. 相似文献

Public stigma towards people with mental health problems has been demonstrated in Western societies. Little is known about non‐Western cultures and whether cultures differ in their perceptions of people with mental health problems. Aim of this study was to examine cultural differences in prejudice, stereotypes, and discrimination towards people with psychosis. Participants were from White British and South Asian backgrounds (N = 128, aged 16–20 years) recruited from two schools and colleges in the United Kingdom. They completed a cross‐sectional survey on affective, cognitive, and behavioural dimensions of stigma. Results revealed significant cultural differences on all three stigma dimensions. South Asians attributed higher anger (prejudice) and dangerousness (stereotypes) to people with psychosis than White British. They also reported lower willingness to help, greater avoidance, and higher endorsement of segregation (discrimination). The effects of ethnic group on helping intentions, avoidance, and segregation endorsement were mediated by anger and by dangerousness. Understanding cultural differences in stigma towards psychosis will be important for designing stigma interventions as well as treatments for people with different cultural backgrounds. 相似文献

This article examines the effects of firm motivation (an intrinsic or extrinsic interest in their product) on perceptions of brand authenticity and anticipated product quality. Specifically, studies 1 and 2 show that an intrinsic motivation increases authenticity perceptions which, in turn, increase perceived product quality, even for negatively regarded products. Studies 3a and 3b demonstrate that motivation affects perceived product quality (through perceived authenticity) by influencing deliberate attribute‐level inferences consumers make about the product, and Study 4 demonstrates that the positive effect of intrinsic motivation (through authenticity) disappears in the presence of objective product attribute information, when such inferences are no longer necessary. These findings suggest that authenticity perceptions are malleable, and they shed light on the mechanism through which brand authenticity leads consumers to anticipate that a brand's products will be higher in quality. 相似文献

The La Bella Figura concept extends to many Italian cultural dimensions including physical appearance, perception of self, and behaviours. La Bella Figura plays an essential role in shaping Italian consumer behaviour and consumerism. The current study sought to understand how women living in Italy conceptualize La Bella Figura and how it affects their day‐to‐day lives, attitudes, and consumption behaviours. This research extracted concepts from Consumer Culture Theory to construct a qualitative codebook and structure thematic data analyses. Semi‐structured interviews were conducted with 30 women aged 18–50 years living in Florence, Italy. Participants were recruited through study flyers, social media, and snowball sampling. Open and axial coding were facilitated by HyperRESEARCH 4.0.1 software to generate key themes. Data were collected and analyzed by trained researchers living in Florence, Italy, who utilized grounded theory techniques to identify emergent themes. Results indicated various components of La Bella Figura contributed to consumer behaviour, namely its influence on identity (i.e., appearance, confidence), lifestyle goals (i.e., health, consumerism), and social norms (i.e., perceptions of others, media). Findings offer practical recommendations for marketers and retailers to appeal to the Italian market through effective and informed mediums. 相似文献

The informative value of time and temporal structure often remains neglected in cognitive assessments. However, next to information about stimulus identity we can exploit temporal ordering principles, such as regularity, periodicity, or grouping to generate predictions about the timing of future events. Such predictions may improve cognitive performance by optimising adaptation to dynamic stimuli. Here, we investigated the influence of temporal structure on verbal working memory by assessing immediate recall performance for aurally presented digit sequences (forward digit span) as a function of standard (1000 ms stimulus-onset-asynchronies, SOAs), short (700 ms), long (1300 ms) and mixed (700–1300 ms) stimulus timing during the presentation phase. Participant's digit spans were lower for short and mixed SOA presentation relative to standard SOAs. This confirms an impact of temporal structure on the classic “magical number seven,” suggesting that working memory performance can in part be regulated through the systematic application of temporal ordering principles. 相似文献
