Three different speech production paradigms assessed C. T. Kello, D. C. Plaut, and B. MacWhinney's (2000) claim that the characteristics of speech production flexibly vary between staged and cascaded modes depending on task demand. All experiments measured response latencies and durations of single words without and with a response deadline. Experiment 1 used a picture-word interference task; Experiment 2 blocked pictures either by semantic category or by word-initial overlap; and Experiment 3 used a Stroop paradigm. In all cases, systematic effects of semantic and form relatedness were obtained on latencies but not on response durations. These results support the assumption that articulation, as assessed by response duration, is never influenced by central cognitive processes once a response has been initiated. 相似文献

Automatic facial recognition is becoming increasingly ubiquitous in security contexts such as passport control. Currently, Automated Border Crossing (ABC) systems in the United Kingdom (UK) and the European Union (EU) require supervision from a human operator who validates correct identity judgments and overrules incorrect decisions. As the accuracy of this human–computer interaction remains unknown, this research investigated how human validation is impacted by a priori face‐matching decisions such as those made by automated face recognition software. Observers matched pairs of faces that were already labeled onscreen as depicting the same identity or two different identities. The majority of these labels provided information that was consistent with the stimuli presented, but some were also inconsistent or provided “unresolved” information. Across three experiments, accuracy consistently deteriorated on trials that were inconsistently labeled, indicating that observers’ face‐matching decisions are biased by external information such as that provided by ABCs. 相似文献

Are Multicultural Courses Addressing Disparities? Exploring Multicultural and Affirmative Lesbian,Gay, and Bisexual Competencies of Counseling and Psychology Students 下载免费PDF全文

Clinical training and counselor competency are essential for ethical practice when working with multiethnic, lesbian, gay, bisexual (LGB), and transgender clients. In this study, the author examined how multicultural courses related to students' (N = 286) LGB and multicultural competencies. Self‐reported multicultural and LGB competencies varied significantly depending on the number and types of diversity education reported. Multicultural courses significantly predicted students' multicultural, but not LGB counselor competency. Political conservatism was the strongest predictor for both multicultural and sexual orientation competencies. La formación y competencias multiculturales afirmativas hacia individuos gays, lesbianas y bisexuales (LGB, por sus siglas en inglés) de consejeros son esenciales para una práctica clínica ética. En este estudio, el autor examinó cómo los cursos multiculturales se relacionaron con las competencias multiculturales de un grupo de estudiantes (N = 286). Las competencias multiculturales y sobre LGB autorreportadas variaron significativamente dependiendo del número y tipos de educación sobre diversidad reportados. Los cursos multiculturales predijeron de forma significativa la competencia multicultural de los estudiantes, pero no la competencia sobre LGB en consejería. La ideología política conservadora fue el predictor más fuerte de las competencias multiculturales y sobre orientación sexual. 相似文献

Despite some principal similarities, there is no systematic comparison between the different types of synesthesia (genuine, acquired and drug-induced). This comprehensive review compares the three principal types of synesthesia and focuses on their phenomenological features and their relation to different etiological models. Implications of this comparison for the validity of the different etiological models are discussed. Comparison of the three forms of synesthesia show many more differences than similarities. This is in contrast to their representation in the literature, where they are discussed in many respects as being virtually similar. Noteworthy is the much broader spectrum and intensity with the typical drug-induced synesthesias compared to genuine and acquired synesthesias. A major implication of the phenomenological comparison in regard to the etiological models is that genuine and acquired synesthesias point to morphological substrates, while drug-induced synesthesia appears to be based on functional changes of brain activity. 相似文献

What factors determine whether mixed-race individuals claim a biracial identity or a monoracial identity? Two studies examine how two status-related factors-race and social class-influence identity choice. While a majority of mixed-race participants identified as biracial in both studies, those who were members of groups with higher status in American society were more likely than those who were members of groups with lower status to claim a biracial identity. Specifically, (a) Asian/White individuals were more likely than Black/White or Latino/White individuals to identify as biracial and (b) mixed-race people from middle-class backgrounds were more likely than those from working-class backgrounds to identify as biracial. These results suggest that claiming a biracial identity is a choice that is more available to those with higher status. 相似文献

Spatial reference in multiple object tracking is available from configurations of dynamic objects and static reference objects. In three experiments, we studied the use of spatial reference in tracking and in relocating targets after abrupt scene rotations. Observers tracked 1, 2, 3, 4, and 6 targets in 3D scenes, in which white balls moved on a square floor plane. The floor plane was either visible thus providing static spatial reference or it was invisible. Without scene rotations, the configuration of dynamic objects provided sufficient spatial reference and static spatial reference was not advantageous. In contrast, with abrupt scene rotations of 20°, static spatial reference supported in relocating targets. A wireframe floor plane lacking local visual detail was as effective as a checkerboard. Individually colored geometric forms as static reference objects provided no additional benefit either, even if targets were centered on these forms at the abrupt scene rotation. Individualizing the dynamic objects themselves by color for a brief interval around the abrupt scene rotation, however, did improve performance. We conclude that attentional tracking of moving targets proceeds within dynamic configurations but detached from static local background. 相似文献

Two studies examine novelty categorization theory's (Förster, Marguc & Gillebaart, 2010) assumption that global compared to local processing styles enhance typicality judgments of atypical objects and thereby enhance liking. We used an artificial category of figures for an alleged computer game including a prototype and three exemplars that varied with respect to similarity with it. Results show that when primed with a global processing style, participants find atypical objects more typical, like them better and process them faster than participants under a local processing style. Mediation analyses show that typicality mediates the effects of processing styles on liking, and that ease of categorization mediates the effect of processing styles on prototypicality. Mood, measured via self report did not influence effects. The studies reflect the fact that judged typicality and its effects are context dependent. 相似文献

Transformations of hand movements by tools such as levers or electronic input devices can invoke performance costs compared to untransformed movements. This study investigated by means of the Psychological Refractory Period (PRP) paradigm at which stage of information processing such tool-transformation costs arise. We used an inversion transformation, that is, the movement of the operating hand was transformed into a spatially incompatible movement of a lever. As a basic tool-transformation effect, the initiation of inverted tool movements was delayed compared to noninverted movements. Experiment 1 suggested a central (or postcentral) locus of this tool-transformation effect and ruled out a (precentral) perceptual locus. Experiments 2 and 3 confirmed the central locus and ruled out a later, motor-related stage of processing. The results show that spatially incompatible tool movements delay a capacity-limited stage of information processing, often referred to as response selection. 相似文献

Keeping aware of the locations of objects while one is moving requires the updating of spatial representations. As long as the objects are visible, attentional tracking is sufficient, but knowing where objects out of view went in relation to one's own body involves an updating of spatial working memory. Here, multiple object tracking was employed to study spatial updating and its neural correlates. In a dynamic 3D-scene, targets moved among visually indistinguishable distractors. The targets and distractors either stayed visible during continuous viewpoint changes or they turned invisible. The parametric variation of tracking load revealed load-dependent activations of the intraparietal sulcus, the superior parietal lobule, and the lateral occipital cortex in response to the attentive tracking task. Viewpoint changes with invisible objects that demanded retention and updating produced load-dependent activation only in the precuneus in line with its presumed involvement in updating spatial working memory. 相似文献
