Can detection of highly stable individual differences in temperament in early childhood be enhanced using measures of resting heart rate (HR) and respiratory sinus arrhythmia (RSA)? The current longitudinal study (N = 216, 50% female; two to four years old) tested the statistical moderating effects of longitudinal change in resting HR and RSA on stability of mother-rated temperament. Children with the smallest decreases in resting HR and smallest increases in resting RSA had the most stable individual differences in effortful control. In contrast, those with the largest increases in resting RSA had the most stable individual differences in surgency. Including information on HR and RSA can be useful, though the effects depend on the trait and physiological indicator in question. 相似文献

The current study examined social support and stress as mediators of the hostility—coronary heart disease (CHD) relationship
as suggested by the psychosocial vulnerability model in a sample of low-income African Americans. Among 95 CHD patients and
30 healthy controls, hostility was negatively correlated with social support, but was not related to minor stress. CHD patients
endorsed higher levels of hostility; however, the relationship between hostility and CHD status was diminished once stress
and social support were included in the model. This study lends partial support for the psychosocial vulnerability model of
hostility in African Americans, but suggests that the relationship between hostility and stress may be impacted by socioeconomic
status. 相似文献

The effects of eating on heart rate variability (HRV) differ between adults and newborns. This may reflect the impact of suckling on the overall psychophysiological and autonomic nervous system maturation. The purpose of the present study was to explore whether the reactions of HRV during feeding change towards the adult pattern during the first 6 months of life. In addition, the effects of non-nutritive and nutritive sucking on heart rate (HR) and HRV were compared. The participants were 23 infants on whom recordings were performed as newborns and at 6, 12 and 24 weeks old. Nutritive sucking caused an increase in HR and a decline in HRV. The results were consistent with previous reports of a decrease in high frequency components of HRV during feeding in newborns, reflecting a decrease in parasympathetic activity. This response was apparent in all four ages studied, and remained similar throughout the 6-month period. However, age as an independent factor seemed to influence both HR and HRV. Pacifier sucking had no significant effects on HRV at any age. The results demonstrate the physical strain that sucking imposes on the baby, with a specific autonomic nervous system response involved. We consider this response an essential part of the overall psychophysiological maturation of infants. 相似文献

In the present study, the frequency, determinants and consequences of three relevant emotions in traffic were investigated. Based on appraisal theory, it was predicted that the combination of three appraisal components (goal congruence, blame and threat) affects the occurrence of anger, anxiety and happiness. Participants (n = 44) filled in a questionnaire containing background and personality variables, and performed a test drive in an instrumented car. During the drive, speed and heart rate were registered and the traffic environment was recorded on video. Participants verbally reported scores for emotions and perceived risk. The most frequently occurring emotion was anxiety, followed by anger and happiness. Emotions while driving were related to emotional traits. Emotions while driving were also related to traffic events: anger and anxiety were both associated with goal incongruent events, and happiness with goal congruent events. Anger was mostly associated with other-blame and anxiety with situation-blame. Anger was mostly associated with events affecting impeded progress, and anxiety with events affecting safety. Anxiety, but not anger or happiness, was associated with increased perceived risk and with increased heart rate. Participants who reported anger drove faster and exceeded the speed limit more often on a 100 km/road section than participants who did not report anger. These and other results are discussed in terms of appraisal theory and state-trait differences in emotion. 相似文献

The central question underlying this study revolves around how children process co-reference relationships—such as those evidenced
by pronouns (him) and reflexives (himself)—and how a slowed rate of speech input may critically affect this process. Previous studies of child language processing
have demonstrated that typical language developing (TLD) children as young as 4 years of age process co-reference relations
in a manner similar to adults on-line. In contrast, off-line measures of pronoun comprehension suggest a developmental delay
for pronouns (relative to reflexives). The present study examines dependency relations in TLD children (ages 5–13) and investigates
how a slowed rate of speech input affects the unconscious (on-line) and conscious (off-line) parsing of these constructions.
For the on-line investigations (using a cross-modal picture priming paradigm), results indicate that at a normal rate of speech
TLD children demonstrate adult-like syntactic reflexes. At a slowed rate of speech the typical language developing children displayed a breakdown in automatic syntactic parsing (again, similar to the pattern seen in unimpaired adults).
As demonstrated in the literature, our off-line investigations (sentence/picture matching task) revealed that these children
performed much better on reflexives than on pronouns at a regular speech rate. However, at the slow speech rate, performance
on pronouns was substantially improved, whereas performance on reflexives was not different than at the regular speech rate.
We interpret these results in light of a distinction between fast automatic processes (relied upon for on-line processing
in real time) and conscious reflective processes (relied upon for off-line processing), such that slowed speech input disrupts
the former, yet improves the latter. 相似文献

This study examined the relationship between heart rate variability (HRV), as an index of individual differences in emotion
regulation, and perception of other-blame, as a mechanism of anger induction. The physiological responses were recorded while
subjects read a story from a computer screen. The story narrated a negative event in self-referred way -dismissal from a job
as the result of a colleague’s action- under conditions of intentionality versus non-intentionality. Cognitive and emotional
variables were assessed by questionnaire immediately after the physiological test. The resulting structural model supports
the conclusion that HRV exerts its regulatory influence directly on perception of other-blame rather than on emotion. In situations
of intentionality, individuals with higher HRV make less extreme evaluation of the offender’s blame, versus those with lower
HRV, thus leading to a reduction in anger reaction. These results suggest that HRV is a direct index of cognitive rather than
emotional regulation. 相似文献

In order to extract the regularities underlying a continuous sensory input, the individual elements constituting the stream have to be encoded and their transitional probabilities (TPs) should be learned. This suggests that variance in statistical learning (SL) performance reflects efficiency in encoding representations as well as efficiency in detecting their statistical properties. These processes have been taken to be independent and temporally modular, where first, elements in the stream are encoded into internal representations, and then the co‐occurrences between them are computed and registered. Here, we entertain a novel hypothesis that one unifying construct—the rate of information in the sensory input—explains learning performance. This theoretical approach merges processes related to encoding of events and those related to learning their regularities into a single computational principle. We present data from two large‐scale experiments with over 800 participants tested in support for this hypothesis, showing that rate of information in a visual stream clearly predicts SL performance, and that similar rate of information values leads to similar SL performance. We discuss the implications for SL theory and its relation to regularity learning. 相似文献
