This research developed a multimodal picture-word task for assessing the influence of visual speech on phonological processing by 100 children between 4 and 14 years of age. We assessed how manipulation of seemingly to-be-ignored auditory (A) and audiovisual (AV) phonological distractors affected picture naming without participants consciously trying to respond to the manipulation. Results varied in complex ways as a function of age and type and modality of distractors. Results for congruent AV distractors yielded an inverted U-shaped function with a significant influence of visual speech in 4-year-olds and 10- to 14-year-olds but not in 5- to 9-year-olds. In concert with dynamic systems theory, we proposed that the temporary loss of sensitivity to visual speech was reflecting reorganization of relevant knowledge and processing subsystems, particularly phonology. We speculated that reorganization may be associated with (a) formal literacy instruction and (b) developmental changes in multimodal processing and auditory perceptual, linguistic, and cognitive skills. 相似文献

ABSTRACT Self-report measures assess mental processes or representations that are consciously accessible. In contrast, implicit measures assess automatic processes that often operate outside awareness. Whereas self-report measures have often failed to show expected relationships with endocrine stress responses, little effort has been made to relate implicit measures to endocrine processes. The present work examines whether implicit affectivity as assessed by the Implicit Positive and Negative Affect Test (IPANAT) predicts cortisol regulation. In Study 1 , implicit low positive affectivity, but not negative affectivity, significantly predicted circadian cortisol release. In Study 2 , implicit negative affectivity, but not positive affectivity, significantly predicted the cortisol response to acute stress. By contrast, cortisol regulation was not predicted by self-reported affectivity. The findings support the use of implicit affectivity measures in studying individual differences in endocrine stress responses and point to a differential role of positive and negative affectivity in baseline versus stress-contingent cortisol release, respectively. 相似文献

The P3 component of the event-related potential (ERP) to an acoustic startle probe is modulated during picture viewing, with
reduced P3 amplitude when participants view either pleasant or unpleasant, as opposed to neutral, pictures. We have interpreted
this as reflecting capture of attentional resources by affective pictures, with fewer resources available for processing the
secondary startle probe. In the present study, we tested this resource allocation hypothesis by presenting either pictures
or sounds as foreground stimuli, with the prediction that P3 amplitude in response to secondary startle probes would be reduced
for affectively engaging foregrounds regardless of modality. Using dense-array electroencephalography and a source estimation
procedure, we observed that P3 amplitude was indeed smaller when startle probes were presented during emotional, as opposed
to neutral, stimuli for both sound and picture foregrounds. Source modeling indicated a common frontocentral maximum of P3
modulation by affect. The data support the notion that emotionally arousing stimuli transmodally attract resources, leading
to optimized processing of the affective stimuli at the cost of the processing of concurrent stimuli. 相似文献

Recent experiments have demonstrated that error-related negativity (ERN) is not only elicited when people commit errors, but
also when they observe others committing errors. The present study investigates whether this observed ERN is also present
when participants observe execution errors in an everyday context. Participants observed short sequences of pictures showing
steps of everyday actions ending either erroneously or correctly. Participants were instructed to indicate by a delayed response
whether the observed action was correctly executed or not. The results showed a large P300 for execution errors compared with
the observation of correct sequences, but no ERN activity was found. The present experiment indicates that the detection of
execution errors in observation does not rely on the error processing mechanism responsible for generating the ERN. The increased
P300 amplitudes suggest a more general monitoring process that signals that the occurrence of unexpected events is involved
in the detection of execution errors. 相似文献

Many recent studies have demonstrated the influence of sublexical frequency measures on language processing, or called for controlling sublexical measures when selecting stimulus material for psycholinguistic studies (Aichert & Ziegler, 2005). The present study discusses which measures should be controlled for in what kind of study, and presents orthographic and phonological syllable, dual unit (bigram and biphoneme) and single unit (letter and phoneme) type and token frequency measures derived from the lemma and word form corpora of the CELEX lexical database (Baayen, Piepenbrock, & Gulikers, 1995). Additionally, we present the SUBLEX software as an adaptive tool for calculating sublexical frequency measures and discuss possible future applications. The measures and the software can be downloaded at www.psychonomic.org. 相似文献

There is evidence that face processing is capacity-limited in distractor interference tasks and in tasks requiring overt recognition memory. We examined whether capacity limits for faces can be observed with a more sensitive measure of visual processing, by measuring repetition priming of flanker faces that were presented alongside a face or a nonface target. In Experiment 1, we found identity priming for face flankers, by measuring repetition priming across a change in image, during task-relevant nonface processing, but not during the processing of a concurrently-presented face target. Experiment 2 showed perceptual priming of the flanker faces, across identical images at prime and test, when they were presented alongside a face target. In a third Experiment, all of these effects were replicated by measuring identity priming and perceptual priming within the same task. Overall, these results imply that face processing is capacity limited, such that only a single face can be identified at one time. Merely attending to a target face appears sufficient to trigger these capacity limits, thereby extinguishing identification of a second face in the display, although our results demonstrate that the additional face remains at least subject to superficial image processing. 相似文献

Grouping operations offer an effective mechanism by which to structure complex visual scenes. Among the various principles that support element integration, closure may be regarded as a main factor in shape extraction. In five experiments, we investigated the impact of grouping by closure on search for target configurations made up of collinearly arranged corner junctions. Systematic variations in the configuration of distractor elements were explored to investigate how the figural information of distractors interferes with target detection. The results showed no search interference for distractor configurations that were open forms. By contrast, distractors making up closed forms reduced the efficiency of search performance, indicating closure as a major contributor to form detection in multielement configurations. In conclusion, the effects reported may be considered to arise from mechanisms of unit formation that support the rapid extraction of salient regions to guide search. 相似文献

This study documented findings on the relation between cognitive functioning (perceptual speed, memory, fluency, and knowledge) and cardiovascular and metabolic disease in a sample of very old adults (ages 70 and older), both cross-sectionally (n=516) and longitudinally (n=206) in a 4-year follow-up. After age, SES, sex, and dementia status were controlled for, 4 diagnoses were negatively associated with cognition: congestive heart failure, stroke, coronary heart disease, and diabetes mellitus, with a joint effect of 0.47 standard deviations. The impact of disease status was largest on perceptual speed and fluency, memory was impacted only by diabetes, and knowledge was not related to any somatic diagnosis. There was no differential decline in participants diagnosed with 1 of these 4 diseases and those who were not. The only cardiovascular risk factor associated with cognitive performance was alcohol consumption. 相似文献
