选取自愿参加本实验的某高校20个教学班级的686人为被试,基于社会网络（social network）的系统动力学（system of dynamic）建模的方法建立了内群体情绪强度的系统动力学模型,并采用心理实验的方法对模型的合理性进行了检验,结果表明,所建立的模型能够与实验数据较好拟合,能较合理地对内群体情绪强度变化的动力学规律进行刻画。此外,通过与以往同类研究对比,本研究还发现：内群体情绪强度的减弱滞后于群体内群体情绪传播的减弱。     

The buffering effect of family functioning on the psychological consequences of headache

The current study aimed to examine whether high family functioning mitigates the association between headache intensity and distress. The sample consisted of 124 patients with chronic or recurrent headache. Patients completed validated questionnaires about headache intensity, family functioning, and distress. Hierarchical regression analyses were performed to examine the interaction between headache intensity and family functioning on distress. Headache intensity was positively associated with distress (r = .28, p = .002). As hypothesized, family functioning moderated this association (B = ?.01, p = .023). More specifically, the positive association between headache intensity and distress was significant only among patients with lower family functioning (B = .01, p < .001) and not among patients with higher levels of family functioning (B = .006, p = .075). Functional families appear to buffer the distress level in patients; they showed relatively low levels of distress regardless of the severity of their headache. In contrast, patients with dysfunctional families who experienced more pain reported more distress, presumably because they did not receive adequate help and support from these families. This study underlines the importance of a broader perspective on family dynamics in coping with pain.     

The illusion of nonmediation in telecommunication: Voice intensity biases distance judgments to a communication partner

The illusion of nonmediation is an experience in mediated communication where individuals respond as if the medium is not there. It is frequently associated with advanced media technology, such as virtual environments and teleconference systems. In this paper, we investigate whether people experience an illusion of nonmediation during interactions as simple as making a phone call. In three experiments, participants were asked to listen to someone's voice on a mobile phone (Experiment 1) or through VoIP software (Experiment 2 and 3) before guessing the location of the person and indicating this location on a map. Results consistently demonstrated that louder voices were judged to be closer, as if the technical mediation was ignored. Combining the three experiments, a small-scale meta-analysis yielded an effect size estimate of d = 0.37 for the ‘louder-as-closer’ effect. Implications of the results and suggestions for future research are discussed.     

Engagement With Self‐Practice/Self‐Reflection as a Professional Development Activity: The Role of Therapist Beliefs

A number of research studies support self‐practice/self‐reflection (SP/SR) as an experiential learning process that facilitates the acquisition of therapeutic skill in a number of cognitive‐behavioural therapy (CBT) competencies and as showing potential as a valuable professional development activity. Engaging therapists to participate in SP/SR programmes is sometimes difficult, and when they are offered the option to participate in SP/SR programmes as part of professional development, relatively few volunteer. This study investigates the role of therapist beliefs about SP/SR as a potential obstacle to engagement. An online survey was developed to assess the strength of 14 commonly held therapist beliefs concerning the consequences of participating voluntarily in a SP/SR programme. Participants were a combined sample of 44 Psychological Wellbeing Practitioners and high‐intensity CBT therapists employed by an Improving Access to Psychological Therapies service in the United Kingdom. Few negative beliefs about SP/SR emerged. The majority of respondents believed SP/SR programmes were relevant to their work situation, but perceived “lack of time” as a significant barrier to participation. Three factors are considered in relation to introducing SP/SR as a workforce professional development activity: (a) The importance of managing therapist perceptions regarding time; (b) SP/SR as a mechanism to increase self‐care and reduce burnout; and (c) The need to focus mental health services' attention on the potential of SP/SR programmes to increase staff morale and improve service delivery.     

Emotion valence,intensity and emotion regulation in immigrants and majority members in the Netherlands

We were interested in interethnic differences and similarities in how emotion regulation strategies (reappraisal, suppression and social sharing) can be predicted by emotion valence and intensity. The sample consisted of 389 Dutch majority members and members of five immigrant groups: 136 Turkish and Moroccan, 105 Antillean and Surinamese, 102 Indonesian, 313 Western and 150 other non‐Western immigrants. In a path model with latent variables we confirmed that emotion regulation strategies were significantly and similarly related to emotion valence and intensity across the groups. Negative emotions were more reappraised and suppressed than positive emotions. Intensity was positively related to social sharing and negatively related to reappraisal and suppression. The Dutch majority group scored higher on emotion valence than Turkish and Moroccan immigrants. Also, the Dutch majority group scored lower on reappraisal than all non‐Western groups, and lower on suppression than Turkish and Moroccan immigrants. We conclude that group differences reside more in mean scores on some components than in how antecedents are linked to regulation strategies.     

Talking about daily emotional events: Psychological well-being moderates the intensity–disclosure link

The intensity of distressing events predicts people’s disclosure of those events at between-person and within-person levels. Depression symptoms seem to attenuate the within-person relation, but past research has not taken a multidimensional view of depression as a moderator. The authors tested whether two constructs related to depression-general psychological well-being and life satisfaction-account for depression’s moderating effects. In a daily diary study, college students (N = 116) rated the intensity of the day’s most unpleasant event and their disclosure of the event each day for 14 days. Participants completed measures of disclosure tendencies, depression symptoms, well-being, and life satisfaction prior to the diary portion of the study. Multilevel modeling analyses revealed moderating effects of disclosure tendencies and depression on the within-person intensity–disclosure relation. However, when psychological well-being and life satisfaction were entered, depression was no longer a significant moderator, but well-being was. Psychological well-being therefore determines the expression of individual differences in the disclosure of daily emotional events.     

Continuous loudness response to acoustic intensity dynamics in melodies: Effects of melodic contour,tempo, and tonality

The aim of this work was to investigate perceived loudness change in response to melodies that increase (up-ramp) or decrease (down-ramp) in acoustic intensity, and the interaction with other musical factors such as melodic contour, tempo, and tonality (tonal/atonal). A within-subjects design manipulated direction of linear intensity change (up-ramp, down-ramp), melodic contour (ascending, descending), tempo, and tonality, using single ramp trials and paired ramp trials, where single up-ramps and down-ramps were assembled to create continuous up-ramp/down-ramp or down-ramp/up-ramp pairs. Twenty-nine (Exp 1) and thirty-six (Exp 2) participants rated loudness continuously in response to trials with monophonic 13-note piano melodies lasting either 6.4 s or 12 s. Linear correlation coefficients > .89 between loudness and time show that time-series loudness responses to dynamic up-ramp and down-ramp melodies are essentially linear across all melodies. Therefore, ‘indirect’ loudness change derived from the difference in loudness at the beginning and end points of the continuous response was calculated. Down-ramps were perceived to change significantly more in loudness than up-ramps in both tonalities and at a relatively slow tempo. Loudness change was also greater for down-ramps presented with a congruent descending melodic contour, relative to an incongruent pairing (down-ramp and ascending melodic contour). No differential effect of intensity ramp/melodic contour congruency was observed for up-ramps. In paired ramp trials assessing the possible impact of ramp context, loudness change in response to up-ramps was significantly greater when preceded by down-ramps, than when not preceded by another ramp. Ramp context did not affect down-ramp perception. The contribution to the fields of music perception and psychoacoustics are discussed in the context of real-time perception of music, principles of music composition, and performance of musical dynamics.     

Emotion regulation choice: the role of environmental affordances

Which emotion regulation strategy one uses in a given context can have profound affective, cognitive, and social consequences. It is therefore important to understand the determinants of emotion regulation choice. Many prior studies have examined person-specific, internal determinants of emotion regulation choice. Recently, it has become clear that external variables that are properties of the stimulus can also influence emotion regulation choice. In the present research, we consider whether reappraisal affordances, defined as the opportunities for re-interpretation of a stimulus that are inherent in that stimulus, can shape individuals’ emotion regulation choices. We show that reappraisal affordances have stability across people and across time (Study 1), and are confounded with emotional intensity for a standardised set of picture stimuli (Study 2). Since emotional intensity has been shown to drive emotion regulation choice, we construct a context in which emotional intensity is separable from reappraisal affordances (Study 3) and use this context to show that reappraisal affordances powerfully influence emotion regulation choice even when emotional intensity and discrete emotions are taken into account (Study 4).     

Cross-modal transfer of conditioned suppression in rats: Effects of US intensity and extinction of the initial conditioning task

In conditioned suppression of water licking behavior by rats, we obtained data indicating general transfer of fear conditioning. A series of experiments resulted in two major findings. First, pairing of a neutral stimulus with a shock in the initial conditioning task facilitated acquisition of subsequent fear conditioning to another neutral stimulus, if the conditioned fear of the initial task was extinguished prior to the second task and if equally strong shocks were employed in both conditioning tasks. Second, omission of the extinction treatment or employment of weaker shocks in the initial task resulted in retardation, rather than facilitation, of the second conditioning task. An application to human clinical settings is discussed.     

表情强度对自闭症儿童面部表情识别影响的实验研究

为探寻自闭症儿童在识别低强度（10%,30%）、中强度（40%,60%）和高强度（70%,90%）的愤怒和开心面部表情时,识别情绪类型的既有能力和差异。采用表情标签范式,用E-prime软件在电脑上呈现不同强度的3D合成面部表情刺激,分别对10名自闭症儿童、10名正常发育儿童和10名智障儿童进行了实验研究。结果发现,自闭症儿童在低强度表情时具有面部表情识别障碍,其对不同强度面部表情识别正确率显著低于智障儿童和正常发育儿童;自闭症儿童面部表情识别正确率与面部表情强度呈正相关,面部表情强度越大,自闭症儿童面部表情识别的正确率越高;自闭症儿童对低强度面部表情识别时,对开心表情的识别正确率高于愤怒表情,但是,在中强度和高强度面部表情识别时,存在显著的愤怒优势效应。
