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

心算应激与特质焦虑、应对风格的关系 总被引:3,自引:1,他引:2
选取38名大学生为被试,采用BIOPAC多导生理记录仪,探讨心算应激对不同人格特质和应对风格的大学生心率(HR)、心率变异性(HRV)及皮肤电反应(GSR)的影响。实验采取2(人格特质:特质焦虑、非特质焦虑)×2(应对风格:注重情绪的应对、注重问题的应对)×3(实验阶段:基线期、任务期、恢复期)的三因素混合设计,要求所有被试经历5分钟的基线期、10分钟的心算任务期和5分钟的恢复期。结果表明:(1)特质焦虑的个体和注重情绪应对的个体在心算应激后的短时间内难以恢复到基线期的生理水平;(2)特质焦虑且注重情绪应对的个体在HR、HF、LF/HF及GSR上表现出明显强的反应性和弱的恢复性;(3)非特质焦虑且注重问题应对的个体在HF和GSR上表现出明显弱的反应性,在LF/HF和GSR上表现出明显强的恢复性。 相似文献

Socio‐emotional behaviour is in part sex‐related in humans, although the contribution of the biological and socio‐cultural factors is not yet known. This study explores sex‐related differences during the earliest communicative exchange, the neonatal imitation in 43 newborn infants (3–96 hours old) using an index finger extension imitative gesture. Results showed that although the experimenter presented comparable stimuli to both sexes, and the total number of movements was similar in boys and girls, girls showed more fine motor movements, a higher number of specific imitative gestures, responded faster during the imitation and showed a higher baseline heart rate during the experiment. Newborn girls, with their faster and more accurate imitative abilities, may create a more responsive and interactive social environment, which in turn may lead to differences in socio‐emotional and cognitive development between girls and boys.

网络旗帜广告的记忆效果 总被引:1,自引:0,他引:1
由于人们对网络旗帜广告效果的质疑,在网络广告的计费方式上也出现了两种计价模式,分别为按照浏览率和点击率来计量广告效果。其本质问题在于单纯浏览是否能够产生广告效果,以及浏览和点击各自所能带来的广告效果差异有多大。本研究利用模糊测量及相应统计方法,就上网者对网络旗帜广告的记忆效果进行测量。结果显示,在单纯浏览的情况下,上网者对网络旗帜广告已经留有印象,但这种记忆效果并不随着浏览次数的增加而显著改善;点击所能带来的广告记忆效果约为单纯浏览对应效果的1.4~1.5倍 相似文献

The objective of this study was to assess, via heart rate, the arousal levels of participants in group trauma reexposure therapy
for posttraumatic stress disorder, and so to better understand this common mode of treatment, particularly in regards to its
presumed curative factor, extinction. Six Vietnam combat-related PTSD inpatients participated twice weekly in group trauma
reexposure therapy during which their electrocardiograms were recorded. Heart rate was quantified continuously off-line. Heart
rates of participantsnot directly engaged in imaginal reexposure to their personal combat traumas consistently exhibited mild linear declines from
the beginnings to the ends of the approximately 2.5 hour sessions. Participants actively engaged in personal combat trauma
reexposure exhibited higher whole-session heart rates. Most also exhibited more specific elevation extending over the later
portions of therapy sessions during which intensive reexposure usually occurred. Surprisingly, no patients exhibitedfocal increases in heart rate concurrent with periods of most intensive traumatic incident review as judged from videotape. Administering
imaginal reexposure in a group context does not preclude substantial physiological (sympathetic) arousal, as is preconditional
for extinction. Under conditions in which the actively engaged reexposure patient is reliably identified, group trauma reexposure
therapy may not provide an opportunity for “vicarious” flooding in nonengaged participants. 相似文献

Pausing under variable-ratio schedules: Interaction of reinforcer magnitude, variable-ratio size, and lowest ratio 总被引:3,自引:3,他引:0 下载免费PDF全文
Pigeons pecked a key under two-component multiple variable-ratio schedules that offered 8-s or 2-s access to grain. Postreinforcement pausing and the rates of responding following the pause (run rates) in each component were measured as a function of variable-ratio size and the size of the lowest ratio in the configuration of ratios comprising each schedule. In one group of subjects, variable-ratio size was varied while the size of the lowest ratio was held constant. In a second group, the size of the lowest ratio was varied while variable-ratio size was held constant. For all subjects, the mean duration of postreinforcement pausing increased in the 2-s component but not in the 8-s component. Postreinforcement pauses increased with increases in variable-ratio size (Group 1) and with increases in the lowest ratio (Group 2). In both groups, run rates were slightly higher in the 8-s component than in the 2-s component. Run rates decreased slightly as variable-ratio size increased, but were unaffected by increases in the size of the lowest ratio. These results suggest that variable-ratio size, the size of the lowest ratio, and reinforcer magnitude interact to determine the duration of postreinforcement pauses. 相似文献
