How left inferior frontal cortex participates in syntactic processing: Evidence from aphasia 总被引:3,自引:0,他引:3
We report on three experiments that provide a real-time processing perspective on the poor comprehension of Broca’s aphasic patients for non-canonically structured sentences. In the first experiment we presented sentences (via a Cross Modal Lexical Priming (CMLP) paradigm) to Broca’s patients at a normal rate of speech. Unlike the pattern found with unimpaired control participants, we observed a general slowing of lexical activation and a concomitant delay in the formation of syntactic dependencies involving “moved” constituents and empty elements. Our second experiment presented these same sentences at a slower rate of speech. In this circumstance, Broca’s patients formed syntactic dependencies as soon as they were structurally licensed (again, a different pattern from that demonstrated by the unimpaired control group). The third experiment used a sentence-picture matching paradigm to chart Broca’s comprehension for non-canonically structured sentences (presented at both normal and slow rates). Here we observed significantly better scores in the slow rate condition. We discuss these findings in terms of the functional commitment of the left anterior cortical region implicated in Broca’s aphasia and conclude that this region is crucially involved in the formation of syntactically-governed dependency relations, not because it supports knowledge of syntactic dependencies, but rather because it supports the real-time implementation of these specific representations by sustaining, at the least, a lexical activation rise-time parameter. 相似文献

This paper presents findings from the field test of a prototype device that collects heart rate sensor data and displays it
for users. The prototype was tested on a football team, including teenage players, their parents and coaches. The findings
include notes on user expectations related to the technology and detailed analyses of the social interactions that took place
during the test. The paper concludes with design implications relating to this application, but also poses challenges for
context-aware computing and machine intelligence in general.

PurposeTo determine the reliability at term of: (1) two methods of measuring fetal heart rate (HR), electrocardiographic (ECG, the ‘gold standard’) and cardiotocographic (CTG) and (2) two ECG methods of measuring maternal HR variability over relatively brief periods of time (s–min).MethodsDuring 20 min of rest (N = 39) and during 2 min of auditory stimulation (mother's recorded voice, n = 19), fetal HR data were collected using an ECG (Monica AN24) and a Hewlett-Packard Model 1351A CTG. Simultaneously, maternal HR data (n = 37) were collected using the same ECG device (Monica AN24) and a second stand-alone cardiac monitor (Spacelab 514T cardiac monitor with a QRS detector).ResultsDuring 20 min of maternal rest, correlations of individual fetal CTG with ECG measures of HR at each second were moderate to high (r = .57–.97) for 77% of fetuses. Correlations of HR averaged over fetuses and over each of the 20 min were high (r = .93–.97); fetal HR averaged over 20 min varied between devices from 0.0 to 0.8 bpm. During 2 min of maternal voice presentation, correlations of fetal HR over each second were moderate to high (r = .54–.99) for 95% of fetuses and high (all rs = .99) when averaged across fetuses in 30 s or 2 min epochs. Average fetal HR between devices over the 2 min voice varied from 0.0 to 0.6 bpm. Correlations and/or % agreement between the two ECG methods of measuring maternal HR were high. Average maternal HR over 10 min showed 81% of pairs with a difference of ≤1 bpm; correlations for HR variability measures varied from r = .89 to .97.ConclusionsGood reliability was demonstrated between individual spontaneous and auditory induced fetal CTG and ECG with high correlations when HR data were averaged over fetuses or in 30–120 s epochs. High reliability of maternal HR measures was obtained using two ECG devices. 相似文献

Implementation intention (IMP) has recently been highlighted as an effective emotion regulatory strategy. Most studies examining the effectiveness of IMPs to regulate emotion have relied on self-report measures of emotional change. In two studies we employed electrodermal activity (EDA) and heart rate (HR) in addition to arousal ratings (AR) to assess the impact of an IMP on emotional responses. In Study 1, 60 participants viewed neutral and two types of negative pictures (weapon vs. non-weapon) under the IMP “If I see a weapon, then I will stay calm and relaxed!” or no self-regulatory instructions (Control). In Study 2, additionally to the Control and IMP conditions, participants completed the picture rating task either under goal intention (GI) to stay calm and relaxed or warning instructions highlighting that some pictures contain weapons. In both studies, participants showed lower EDA, reduced HR deceleration and lower AR to the weapon pictures compared to the non-weapon pictures. In Study 2, the IMP was associated with lower EDA compared to the GI condition for the weapon pictures, but not compared to the weapon pictures in the Warning condition. ARs were lower for IMP compared to GI and Warning conditions for the weapon pictures. 相似文献

与传统信息不同,网络信息具有可以主动增加的互动特征,本研究探讨这种特征对网络情境下决策加工过程的影响。通过改进的信息板技术追踪决策过程。实验一设置可否“主动增加信息”两种情境进行对照研究,发现引入主动增加功能后被试的搜索深度降低,先前知识的水平影响信息加工的模式;实验二设置可以连续要求增加信息的连续任务,比较不同的增加路径和选择阶段的影响,发现被试的搜索深度逐步降低,更多采用非补偿性的策略。两个实验均有超过半数的被试要求增加信息,连续任务有着32%的回头率,研究者推论在信息不断增加的情况下,被试的信息搜索行为更具选择性。 相似文献

This exploratory application of the infant simulator with two couples is designed to illustrate individual reactivity and coparenting behaviors in young couples in serious relationships who do not yet have children. A 35-min protocol with standardized onsets and offsets of inconsolable baby cries was used to capture partner’s individual behavioral and physiological responses as well as the couple’s joint efforts to soothe the crying baby. Task feasibility was demonstrated by couples’ persistent and wide-ranging efforts to calm the baby including rocking, feeding, changing, talking to the baby, and singing. Within-person fluctuations in ongoing heart rate (HR) and electrodermal activity (EDA) through the protocol suggested evidence of heightened physiological reactivity during baby crying compared to silence. During bouts of crying, higher HR also was evidenced when participants took the lead in caregiving as contrasted with assisting or busying themselves in another task. Behavioral observations indicated that this task elicited examples of coparenting behaviors including cooperation, support, undermining, and negotiating the division of labor. These preliminary pilot data demonstrate the potential of infant simulator paradigms with couples who are not yet pregnant but envision being future parents, and set the stage for future research to identify how individual and couple characteristics might impact reactions to shared baby caregiving. 相似文献

Due to the low quality of life (QoL) in patients with heart failure, many researchers attempted to find new ways to improve the QoL in these patients. This study was conducted to determine the relationship between QoL and religious attitudes of patients with heart failure. In this cross-sectional study, 130 male and female patients with heart failure were selected based on the inclusion criteria. Data were collected using 36-item short form Quality of Life and structured Religious Attitude Questionnaires. The average age of subjects was 59.50?±?12.29; also, 52.3% of them were female. A significant relationship was observed between patients’ QoL and their religious attitudes in mental (p?=?.03) and general health (p?=?.04) dimensions, but religious attitude had no significant correlation with physical health dimension (p?=?.66) and the total score of QoL (p?=?.30). At the end, it was concluded that religious beliefs can improve patients’ quality of life. 相似文献

Cardiovascular reactivity during spousal conflict is considered to be one of the main pathways for relationship distress to impact physical, mental, and relationship health. However, the magnitude of association between cardiovascular reactivity during laboratory marital conflict and relationship functioning is small and inconsistent given the scope of its importance in theoretical models of intimate relationships. This study tests the possibility that cardiovascular data collected in laboratory settings downwardly bias the magnitude of these associations when compared to measures obtained in naturalistic settings. Ambulatory cardiovascular reactivity data were collected from 20 couples during two relationship conflicts in a research laboratory, two planned relationship conflicts at couples’ homes, and two spontaneous relationship conflicts during couples’ daily lives. Associations between self‐report measures of relationship functioning, individual functioning, and cardiovascular reactivity across settings are tested using multilevel models. Cardiovascular reactivity was significantly larger during planned and spontaneous relationship conflicts in naturalistic settings than during planned relationship conflicts in the laboratory. Similarly, associations with relationship and individual functioning variables were statistically significantly larger for cardiovascular data collected in naturalistic settings than the same data collected in the laboratory. Our findings suggest that cardiovascular reactivity during spousal conflict in naturalistic settings is statistically significantly different from that elicited in laboratory settings both in magnitude and in the pattern of associations with a wide range of inter‐ and intrapersonal variables. These differences in findings across laboratory and naturalistic physiological responses highlight the value of testing physiological phenomena across interaction contexts in romantic relationships. 相似文献
