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

Loneliness can be regarded as an epidemic of modern society that is becoming increasingly problematic for millions of people.
Adolescents are particularly susceptible to the development of this kind of emotional distress. Although many causes of loneliness
can be identified, some researchers are of the opinion that it can also be attributed to unpleasant childhood experiences
that result in unfulfilled needs relating to intimacy. In this research study, the relationship between loneliness and adolescents’
attitudes towards their fathers was investigated. In order to achieve this goal, information was gathered from 1068 South
African respondents. Biographical questionnaires were administered and a Loneliness Scale was applied. In addition, adolescents’
attitudes towards their fathers were measured by means of a Fathers Questionnaire. Steps were taken to determine which of
the independent variables, namely gender, age, race, language and socio-economic status, contributed significantly to the
prediction of loneliness. In order to process the acquired information, a stepwise multiple regression analysis was conducted.
The most important finding of this study is that adolescents’ attitudes towards their fathers comprise the most prominent
predictor of loneliness during adolescence. The results also indicated that all of the independent variables had a statistically
significant influence on loneliness. 相似文献

Nondeprived male Sprague-Dawley rats that were given scheduled access to running wheels for 60 min daily ran immediately and energetically. Intraperitoneal injections of 400 micrograms/kg pancreatic glucagon and 0.15 microgram/kg cholecystokinin octapeptide had no effect on scheduled running, but significantly inhibited feeding when the rats were offered condensed milk instead of access to the running wheels. This is consistent with the hypothesized function of these peptides as postprandial satiety signals. In contrast, 0.5 mg/kg amphetamine and 75 microM/kg LiCl, which produced similar degrees of anorexia, inhibited running by about 50%. Amphetamine, but neither peptide, also inhibited water drinking and disrupted the behavioral sequence of postprandial satiety. The distance run during scheduled running tests was inversely related to body weight, but the patterns of the drugs' effects were not altered by baseline running differences. Scheduled wheel running is a robust consummatory behavior that appears to provide a relatively valid, simple, and sensitive test of the behavioral specificity of pharmacological anorexia. 相似文献

To study the involvement of endogenous opioid peptides in the development of shock-induced fighting, naloxone (2 mg/kg) or beta-endorphin (10 micrograms/kg) was administered subcutaneously immediately after the session and during nine consecutive daily sessions to rats repeatedly exposed to electric shocks. beta-Endorphin blocked the development of shock-induced fighting while naloxone facilitated it but only when shock-induced fighting occurred at a low rate. The effects of beta-endorphin were time dependent since when beta-endorphin was injected 90 min after the shock session instead of immediately after, its impairing effect disappeared. In addition, naloxone blocked the impairment produced by beta-endorphin. Differential postsession treatment of each member of pairs of rats with naloxone and beta-endorphin resulted in a higher probability of rats treated with naloxone to be dominant over rats treated with beta-endorphin in the test situation. These results are discussed in relation with the possible involvement of endogenous opioids in the modulation of the physiological consequences of defensive behavioral responses to shock. 相似文献

Recently, certain Minnesota Multiphasic Personality Inventory (MMPI) and Millon Clinical Multiaxial Inventory (MCMI) scales have seen increasing usage for the measurement of DSM-III personality disorders. The current study sought to identify the convergent and discriminant validity of these two sets of scales for this purpose. In general, the results indicated significant convergence across the two instruments. However, better convergent validity was found for scales representing those DSM-III disorders which are most consistent with the typology upon which the MCMI was based. In particular, convergent and discriminant validity results were poorest for Compulsive, Antisocial, and Passive-Aggressive personality scales. 相似文献

This article is an introduction to C. G. Jung’s handwritten note on natural numbers (in this issue), which became the basis of Marie-Louise von Franz’s book Number and Time. I present the historical background of Jung’s note and discuss part of its content using mostly Jung’s own words. 相似文献

Voices transmit social signals through speech and/or prosody. Emotional prosody conveys key information about the emotional state of a speaker and is thus a crucial cue that one has to detect in order to develop efficient social communication. Previous studies in adults reported different brain responses to emotional than to neutral prosodic deviancy. The aim of this study was to characterize such specific emotional deviancy effects in school-age children. The mismatch negativity (MMN) and P3a evoked potentials, reflecting automatic change detection and automatic attention orienting, respectively, were obtained for neutral and emotional angry deviants in both school-age children (n = 26) and adults (n = 14). Shorter latencies were found for emotional than for neutral preattentional responses in both groups. However, whereas this effect was observed on the MMN in adults, it appeared in an early discriminative negativity preceding the MMN in children. A smaller P3a amplitude was observed for the emotional than for the neutral deviants at all ages. Overall, the brain responses involved in specific emotional change processing are already present during childhood, but responses have not yet reached an adult pattern. We suggest that these processing differences might contribute to the known improvement of emotional prosody perception between childhood and adulthood. 相似文献

If temporal position of a frequency inflection is the most salient communication cue in Japanese macaque smooth early and smooth late high coos, then macaques should perceive coos differing only along the early-late dimension as belonging to different classes. The perceived similarity of synthetic coos and temporally reversed variants were evaluated, using multidimensional scaling of macaque discrimination latencies. Original calls and calls temporally reversed in the frequency domain could be discriminated if the peak was near a call endpoint but not if the frequency peak in the original call was near the coo midpoint. Perceived similarity of such calls was inversely related to the amount of frequency modulation. Temporal reversals of amplitude contours were also conducted. Although macaques are quite sensitive to amplitude increments, reversal of the relatively flat amplitude contours of these calls did not affect discrimination responses. 相似文献
