This study examined the relationship between PMS and emotion-related electromyographic facial activity at different phases of the menstrual cycle. Twenty-four women of reproductive age (12 with PMS, 12 controls) participated in two EMG sessions (T1 and T2) in which they were shown photographic images that can elicit various emotions (IAPS stimuli). T1 took place in the follicular phase, T2 in the luteal phase. The activity of the musculus depressor anguli oris ("depressor", expression of sadness) was measured. Depressor activity was compared to activity of musculus orbicularis oculi ("orbicularis"; expression of joy). ANOVA yielded a significant increase of the activity of the depressor at T2 in the PMS group. The PMS group showed more frequent depressor activity during the luteal than the follicular phase. Orbicularis activity did not change from T1 to T2. Conclusions: The PMS group experienced various visual stimuli in a more depressed way during the luteal phase. 相似文献

During the last years increasing attention has been paid to young children and adolescents with sexual coercive behaviour. During the year 2007 altogether 232 boys and 30 girls under the age of 14 years were reported to the police because of sexual assaults. In NRW an increasing number of in- and out-patient institutions offers specific and unspecific treatment programs for these children. The major aim of our study, which is supported by the Ministry of Employment, Health and Social Affairs of the state of NRW, is to evaluate the wide range of different treatment programs and to find predictors for successful or difficult treatment outcomes. Furthermore we are interested in differences between children with sexual problem behaviour and children with exclusively aggressive problems. So far 23 institutions take part in our research project and our total sample currently consists of 75 boys between 9 - 15 years. A psychometric test battery is applied at the beginning of individual treatment. Our first results highlight differences in socio-demographic data between children with sexual coercive behaviour and children with exclusively aggressive behaviour problems. Compared to children with exclusively aggressive problem behaviour, children with sexual problem behaviour come more often from incomplete families with no male parent, have experienced more psychological and physical violence and have been more often victims of sexual abuse. Compared to children with exclusively aggressive behaviour problems they score significantly higher on the “Depression / Anxiety” scale of the SPS-J, although average T-scores for both groups are within the normal range. Regarding cognitive functioning there are no significant differences between both groups. 相似文献

Maladaptive social behavior is one of the defining characteristics of psychopathic personality disorder. Nevertheless, maladaptive social behavior has only rarely been observed among psychopaths in experimentally controlled situations. The authors assessed the behavior of criminal psychopaths from high-security psychiatric hospitals in a computer simulation of a social dilemma situation. The psychopaths showed a markedly higher proneness to competitive (i.e., noncooperative) behavior than did healthy adults from the general population. The odds ratio between defection and being a psychopath was estimated at 7.86 in the sample. The probability to choose selfish instead of cooperative behavior was significantly linked to the following subscales of the Psychopathy Personality Inventory-Revised (S. O. Lilienfeld & M. R. Widows, 2005): rebellious nonconformity, Machiavellian egocentricity, and the total score. On average, the psychopathic participants accumulated higher gain and more strongly exploited their counterpart than did the healthy participants. 相似文献

The authors postulate and show a speed advantage in the processing of positive information and hypothesize that this advantage is caused by the higher density of positive information in memory: Positive information is more similar to other positive information, in comparison with the similarity of negative information to other negative information. This "density" hypothesis is supported by multidimensional scaling of evaluative stimuli and response latency experiments. The relevance and explanatory power of the hypothesis is demonstrated by secondary data analyses of prior research in the evaluative priming paradigm. The final discussion is concerned with further theoretical implications of the density hypothesis, its generality and limitations, and its relation to other theoretical conceptions and applications. 相似文献

The present study examines consequences of high peer pressure on academic performance in mathematics among 14-year-old middle-school
students in Germany, Canada, and Israel. Its core assumption is that students with very high abilities in mathematics underachieve
in order to avoid social exclusion (in the form of being called, e.g., nerds) in their schools. Altogether almost 1,700 students
were surveyed in the three cultures. Findings of the study make it obvious that—concerning achievement in mathematics—the
primary victims of peer pressure in middle school are girls, boys more likely than girls being the perpetrators. High individual
preferences of achievement values can buffer effects of peer pressure. However, from a pedagogical point of view it may nevertheless
seem an option to teach mathematics in mono-gender courses, in order to improve the chances of both girls and boys to show
an academic performance that concurs with their real competence. 相似文献

Forgetting in immediate serial recall: decay, temporal distinctiveness, or interference? 总被引:1,自引:0,他引:1
Three hypotheses of forgetting from immediate memory were tested: time-based decay, decreasing temporal distinctiveness, and interference. The hypotheses were represented by 3 models of serial recall: the primacy model, the SIMPLE (scale-independent memory, perception, and learning) model, and the SOB (serial order in a box) model, respectively. The models were fit to 2 experiments investigating the effect of filled delays between items at encoding or at recall. Short delays between items, filled with articulatory suppression, led to massive impairment of memory relative to a no-delay baseline. Extending the delays had little additional effect, suggesting that the passage of time alone does not cause forgetting. Adding a choice reaction task in the delay periods to block attention-based rehearsal did not change these results. The interference-based SOB fit the data best; the primacy model overpredicted the effect of lengthening delays, and SIMPLE was unable to explain the effect of delays at encoding. The authors conclude that purely temporal views of forgetting are inadequate. 相似文献

Emotions evoked by the sound of music: characterization, classification, and measurement 总被引:1,自引:0,他引:1
One reason for the universal appeal of music lies in the emotional rewards that music offers to its listeners. But what makes these rewards so special? The authors addressed this question by progressively characterizing music-induced emotions in 4 interrelated studies. Studies 1 and 2 (n=354) were conducted to compile a list of music-relevant emotion terms and to study the frequency of both felt and perceived emotions across 5 groups of listeners with distinct music preferences. Emotional responses varied greatly according to musical genre and type of response (felt vs. perceived). Study 3 (n=801)--a field study carried out during a music festival--examined the structure of music-induced emotions via confirmatory factor analysis of emotion ratings, resulting in a 9-factorial model of music-induced emotions. Study 4 (n=238) replicated this model and found that it accounted for music-elicited emotions better than the basic emotion and dimensional emotion models. A domain-specific device to measure musically induced emotions is introduced--the Geneva Emotional Music Scale. 相似文献

Zusammenfassung Das Wissen über Psychopathologie, Ätiopathogenese und Behandlungsmöglichkeiten der Borderline-Persönlichkeitsstörung (BPS) hat sich in den letzten Jahren deutlich verbessert. Heute sehen die meisten Wissenschaftler eine generalisierte Störung der Affektregulation im Zentrum der BPS, deren Ursachen in Wechselwirkungen zwischen genetischen Faktoren, traumatischen biographischen Erfahrungen und dysfunktionalen Verhaltensmustern liegen. Störungsspezifische Therapieverfahren, insbesondere die Dialektisch Behaviorale Therapie (DBT) nach Linehan, flankiert von psychopharmakologischer Behandlung, zeigen gute Behandlungsergebnisse sowohl im stationären als auch im ambulanten Bereich. In jüngster Zeit wurden viel versprechende Konzepte zur Behandlung schwerer komorbider Störungen [Alkohol und Drogenabhängigkeit, Posttraumatische Belastungsstörung (PTBS)] entwickelt. 相似文献

Previous studies have frequently applied a combination of line-bisection tasks (in which participants indicate the middle of a line) and obstacle avoidance tasks (in which participants move their hand between two obstacles) with the aim of revealing perception–action dissociations in certain neurological disorders, such as visual form agnosia and optic ataxia. However, valid conclusions about the underlying processing pathways can only be drawn if participants apply the same strategy in both tasks (i.e. finding the middle between the obstacles). Yet, this assumption has never been tested directly. In this experiment, we investigated whether participants perform obstacle avoidance and line-bisectioning using similar strategies by manipulating the position of the obstacles and the start position of the hand relative to the obstacles. Our results indicate that the lateral hand position during obstacle avoidance does not only vary as a function of obstacle location but also strongly depends on the start position. Moreover, participants showed increased sensitivity to obstacle shifts occurring closer to the hand's start position. In contrast, during line-bisectioning the sensitivity to obstacles shifts was unaffected by the hand's start position. The findings suggest that during obstacle-avoidance the need to keep a safe distance from the obstacles is balanced with the requirement to minimise energetic demands. In contrast, the main intention during line-bisectioning is to move to the perceived midpoint as accurately as possible. The fact that very different constraints underlie trajectory planning in both tasks implies that caution has to be taken when interpreting differences in performance levels. 相似文献

It was proposed that grasping is a relatively stereotyped movement pattern which can be subdivided into the components of manipulation, transport, and orientation of the hand. However, it is still a matter of debate whether these components are independent of each other. In three experiments we altered the start posture of the hand by either changing the size of the start aperture or the orientation of the hand prior to movement onset. The variation of the aperture size primarily affected the manipulation component of the grip resulting in an overall change of the pre-shaping profile. In contrast, an alteration of the start orientation affected the manipulation and the transport components to a similar extent. These results give further evidence that hand orientation is neither planned nor controlled independently from the other movement components. Moreover, when the grip had to match specific object properties, adjustments were mainly achieved within the first movement part. In contrast, when there were no movement constraints the final finger positions were influenced by the initial start posture of the hand. We found no evidence for a fixed spatial or temporal coupling of the grasp and the transport component in our experiments. 相似文献
