Dreams are more negative than real life: Implications for the function of dreaming

Dream content studies have revealed that dream experiences are negatively biased; negative dream contents are more frequent than corresponding positive dream contents. It is unclear, however, whether the bias is real or due to biased sampling, i.e., selective memory for intense negative emotions. The threat simulation theory (TST) claims that the negativity bias is real and reflects the evolved biological function of dreaming. In the present study, we tested the hypothesis of the TST that threatening events are overrepresented in dreams, i.e., more frequent and more severe in dreams than in real life. To control for biased sampling, we used as a baseline the corresponding negative events in real life rather than the corresponding positive events in dreams. We collected dream reports (N=419) and daily event logs (N=490) from 39 university students during a two-week period, and interviewed them about real threat experiences retrievable from autobiographical memory (N=714). Threat experiences proved to be much more frequent and severe in dreams than in real life, and Current Dream Threats more closely resembled Past than Current Real Threats. We conclude that the TST's predictions hold, and that the negativity bias is real.     

Expectancy bias mediates the link between social anxiety and memory bias for social evaluation

Social anxiety (SA) involves a multitude of cognitive symptoms related to fear of evaluation, including expectancy and memory biases. We examined whether memory biases are influenced by expectancy biases for social feedback in SA. We hypothesised that, faced with a socially evaluative event, people with higher SA would show a negative expectancy bias for future feedback. Furthermore, we predicted that memory bias for feedback in SA would be mediated by expectancy bias. Ninety-four undergraduate students (55 women, mean age = 19.76 years) underwent a two-visit task that measured expectations about (Visit 1) and memory of (Visit 2) feedback from unknown peers. Results showed that higher levels of SA were associated with negative expectancy bias. An indirect relationship was found between SA and memory bias that was mediated by expectancy bias. The results suggest that expectancy biases are in the causal path from SA to negative memory biases for social evaluation.     

Mood-congruent false memories persist over time

There are two contrasting hypotheses that attempt to explain how emotion perception might be organised in the brain. One suggests that all emotions are lateralised to the right hemisphere whereas the other suggests that emotions may be differently lateralised according to valence. Here these two theories are contrasted, in addition to considering the role of emotional intensity in explaining possible differences in strength of lateralisation across emotions. Participants completed a Chimeric Faces Test for each of the six basic emotions: anger, disgust, fear, happiness, sadness and surprise. All emotions showed significant lateralisation to the right hemisphere, however, differences in strength of lateralisation within the right hemisphere were found. Stronger patterns of right hemisphere lateralisation were found for positive emotions and for emotions of higher intensity. The results support the right-hemisphere hypothesis, but suggest that there may be variability in organisation within the right hemisphere across different types of emotion.     

Outcome expectations and work design characteristics in post-retirement work planning

Today, a growing number of individuals decide to work beyond normal retirement age (Eurofound, 2012). Research has revealed influencing factors for post-retirement work at the individual, job and organizational, family, and socioeconomic levels. However, not much is known about post-retirement work planning and its antecedents. The purpose of this study is to examine the effects of outcome expectations regarding post-retirement work and two work design characteristics (i.e., physical demands and social support at work) on post-retirement work planning by applying the framework of social cognitive career theory (SCCT; Lent, Brown, & Hackett, 1994). Data from 1065 employees of a German logistics company were used in this study. Results provide support for SCCT to be a suitable theoretical framework for understanding post-retirement career planning and thereby expand the application of SCCT to a new field. Furthermore, multilevel analysis revealed that physical demands were negatively related to the intention to continue to work for the pre-retirement employer after retirement entry, whereas social support at work strengthened the relationship between outcome expectations and same-employer-post-retirement work intention. Organizations who want their retired employees to continue to work in retirement should develop interventions to strengthen post-retirement work outcome expectations. An increase in social support at work as well as a reduction in physical demands may also contribute to increased participation in continued work with the same employer in retirement.     

Measuring psychotherapy outcomes in routine practice: Examining Slovak versions of three commonly used outcome instruments

This study examined the Slovak mutations of three outcome measures for routine practice i.e. the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM), the Outcome Questionnaire – 45 (OQ-45), the Outcome Rating Scale (ORS), and one control measure the Symptom Checklist 10 Revised (SCL-10R), with regard to their concordance or differences in outcome classification of pre-post change, when used by the same patients and when the criteria used for establishing recovery and improvement status are based on the same sample. Method: Non-clinical (252) and clinical (202) samples were used for the standardisation of all instruments. A portion of the clinical participants (N?=?140) completed all measures at the end of their treatment. Results: The CORE-OM, and the SCL-10R indicated a higher number of recovered and improved clients. With regard to the pre-post differences as expressed in the effect size, the CORE-OM showed the highest pre-post difference (pre-post effect size .98), followed by the ORS (.87), the SCL-10R (.83) and finally with the OQ-45 (.69). Conclusion: Even very similar instruments developed on the basis of similar theoretical conceptualisations and empirical findings may report different pre-post outcomes.     

Priming of actions increases sense of control over unexpected outcomes

Sense of agency (SoA) refers to the feeling that we are in control of our own actions and, through them, events in the outside world. SoA depends partly on retrospectively matching outcomes to expectations, and partly on prospective processes occurring prior to action, notably action selection.To assess the relative contribution of these processes, we factorially varied subliminal priming of action selection and expectation of action outcomes. Both factors affected SoA, and there was also a significant interaction. Compatible action primes increased SoA more strongly for unexpected than expected outcomes. Outcome expectation had strong effects on SoA following incompatible action priming, but only weak effects following compatible action priming. Prospective and retrospective SoA may have distinct and complementary functions.     

Do in-vivo behaviors predict early response in family-based treatment for anorexia nervosa?

The aim of the study is to explore whether identified parental and patient behaviors observed in the first few sessions of family-based treatment (FBT) predict early response (weight gain of 1.8 kg by session four) to treatment. Therapy film recordings from 21 adolescent participants recruited into the FBT arm of a multi-site randomized clinical trial were coded for the presence of behaviors (length of observed behavior divided by length of session recording) in the first, second and fourth sessions. Behaviors that differed between early responders and non-early responders on univariate analysis were entered into discriminant class analyses. Participants with fewer negative verbal behaviors in the first session and were away from table during the meal session less had the greatest rates of early response. Parents who made fewer critical statements and who did not repeatedly present food during the meal session had children who had the greatest rates of early response. In-vivo behaviors in early sessions of FBT may predict early response to FBT. Adaptations to address participant resistance and to decrease the numbers of critical comments made by parents while encouraging their children to eat might improve early response to FBT.     

青少年与成人不同情绪刺激调节效应的差异

旨在探究增强调节和减弱调节调节效应量的年龄差异。通过两个实验系统考察青少年和成人对不同情绪刺激使用不同调节策略时,调节效应的差异。实验一采用“情绪反应性—调节图片任务（REAR-I Task）”考察了35名青少年和35名成人情绪调节的效应量。实验二进一步对情绪图片的唤醒度进行分组（高唤醒/低唤醒）,考察了59名青少年和59名成人情绪调节的效应量。结果验证了研究假设：整体而言,对不同效价和唤醒度情绪刺激采用增强调节或减弱调节时,成人的调节效应量均大于青少年,对正性情绪的减弱调节方面尤为明显。
