Effects of intranasal oxytocin on 'compassion focused imagery'

This study explored the effects of oxytocin on Compassion Focused Imagery (CFI), that is, imagining another "mind" being deeply compassionate to oneself, and the interaction of these effects with self-criticism and feeling socially safe with others. Forty-four healthy participants (29 men and 15 women) completed self-report measures of self-criticism, attachment style, and social safeness before taking part in a double-blind randomized placebo controlled study. They attended two imagery sessions, receiving oxytocin in one and a placebo in the other. Positive affect was measured before and after each imagery session, and "imagery experience" was assessed after each session. Overall, oxytocin increased the ease of imagining compassionate qualities but there were important individual differences in how CFI was experienced. Participants higher in self-criticism, lower in self-reassurance, social safeness, and attachment security had less positive experiences of CFI under oxytocin than placebo, indicating that the effects of oxytocin on affiliation may depend on attachment and self-evaluative styles.     

Direct and indirect measures of spider fear predict unique variance in children's fear-related behaviour

This study investigated whether direct and indirect measures predict unique variance components of fearful behaviour in children. One hundred eighty-nine children aged between 9 and 12 performed a pictorial version of the emotional Stroop task (EST), filled out the Spider Anxiety and Disgust Screening for Children (SADS-C), the Spider Phobia Questionnaire for Children (SPQ-C), and took part in a Behavioural Assessment Test (BAT). The EST did not correlate with self-reports. Correlations of the self-reports and the BAT remained significant after partialling out EST performance. Likewise, the EST and the BAT still correlated significantly with each other when controlling for the self-reports. This indicates that both direct and indirect measures are useful for predicting unique variance components of fearful behaviour in children. Moreover, it may explain why some previous studies have not found a relationship between self-reported fear and EST performance.     

Enhanced priming for trauma-related words predicts posttraumatic stress disorder

There is preliminary evidence that enhanced priming for trauma-related cues plays a role in posttraumatic stress disorder (PTSD). A prospective study of 119 motor vehicle accident survivors investigated whether priming for trauma-related stimuli predicts PTSD. Participants completed a modified word-stem completion test comprising accident-related, traffic-related, general threat, and neutral words at 2 weeks post-trauma. Priming for accident-related words predicted PTSD at 6 months follow-up, even when initial symptom levels of PTSD and depression and priming for other words were controlled. The results are in line with the hypothesis that enhanced priming for traumatic material contributes to the development of chronic PTSD.     

The Depressive Attributions Questionnaire (DAQ): Development of a Short Self-Report Measure of Depressogenic Attributions

A depressogenic attributional style, i.e., internal, stable and global causal interpretations of negative events, is a stable vulnerability factor for depression. Current measures of pessimistic attributional style can be time-consuming to complete, and some are designed for specific use with student populations. We developed and validated a new short questionnaire suitable for the measurement of depressogenic attributions in clinical settings, the Depressive Attributions Questionnaire (DAQ). The 16-item DAQ, and measures of depression and related cognitive concepts were completed by three samples of depressed patients and matched controls, or depressed and non-depressed participants who had been exposed to a recent uncontrollable stressful life event (total N = 375). The DAQ had high (i) internal reliability, (ii) test-retest reliability, (iii) convergent, discriminant and construct validity. It predicted a diagnosis of major depression at 6 months after an uncontrollable stressor, over and above what could be predicted from initial depression severity. Depressed patients rated the scale as acceptable. The DAQ may be a useful short measure of depressogenic attributions, which is easy to administer, and predicts concurrent and future depression. It has possible applications as a screening measure for risk of depression, or as a treatment process measure.     

Different social motives in the gestural communication of chimpanzees and human children

Both chimpanzees and human infants use the pointing gesture with human adults, but it is not clear if they are doing so for the same social motives. In two studies, we presented chimpanzees and human 25-month-olds with the opportunity to point for a hidden tool (in the presence of a non-functional distractor). In one condition it was clear that the tool would be used to retrieve a reward for the pointing subject (so the pointing was selfish or 'for-me'), whereas in the other condition it was clear that the tool would be used to retrieve the reward for the experimenter (so the pointing was helpful or 'for-you'). The chimpanzees pointed reliably only when they themselves benefited, whereas the human children pointed reliably no matter who benefited. These results are interpreted as evidence for the especially cooperative nature of human communication.     

The factor structure of the Autobiographical Memory Test in recent trauma survivors

The objective of this study was to examine the psychometric properties of the Autobiographical Memory Test (AMT), which is widely used to measure overgeneral autobiographical memory in individuals with depression and a trauma history. Its factor structure and internal consistency have not been explored in a clinical sample. This study examined the psychometric properties of the AMT in a sample of recent trauma survivors (N = 194), who completed the AMT 2 weeks after a trauma. Participants were also assessed with structured clinical interviews for current acute stress disorder and current and past major depressive disorder. Confirmatory factor analysis and item response theory were used to analyze the AMT in the whole sample. The factor structure of the AMT was also compared for (a) individuals with and without lifetime major depressive disorder and (b) individuals with current (posttrauma) major depressive disorder and/or acute stress disorder versus those with neither disorder. In all of these analyses, the AMT with cues of positive and negative valence had a 1-factor structure, which replicates work in nonclinical samples. Based on analyses of the whole sample, scores from the AMT had a reliability estimate of .72, and standard error of measurement was lowest for people who scored low on memory specificity. In conclusion, the AMT measures 1 factor of memory specificity in a clinical sample and can yield reliable scores for memory specificity. More psychometric studies of the AMT are needed to replicate these results with similar and other clinical populations.     

Athletes' perceptions of multilevel changes related to competing at the 2008 Beijing Olympic Games

ObjectivesTaking into account the need for applied research on the most effective ways to prepare Olympians psychologically, the first purpose of this study was to gain more insight into the changes perceived by four athletes in view of their participation in the 2008 Beijing Olympic Games. The second purpose of this study was to illustrate how using a holistic and dynamic approach to the identification of the perceptions of these athletes' Olympic experiences can provide information relevant for the provision of individual ASP support to these athletes.DesignUsing a prospective design athletes' perceptions of changes were gathered prior, during as well as after the Olympic Games.MethodsA combination of interview (pre and post Olympic Games) and self-reporting (during Olympic Games) was used to describe athletes' perceptions of changes occurring at athletic, psychological, psychosocial, academic/vocational level.ResultsResults confirmed in first instance athletes' perceptions of the multifaceted nature of their Olympic experience. In second instance, the use of a dynamic and holistic perspective allowed to identify that participants perceived (a) during the phase prior to the Olympic Games 14 changes at all four levels, (b) during the Olympic Games eight changes at three levels, and (c) during the phase after returning from the Olympic Games 11 changes having occurred at four levels.ConclusionsThis study showed the usefulness of using a dynamic and holistic perspective not only in order to identify athletes' perceptions of their Olympic experiences, but also to enhance ASP practitioners' knowledge on the needs for a holistic and dynamic ASP-support provision. In this way, the effectiveness and efficiency of ASP practitioners working with athletes preparing for, or competing at the Olympic Games could be enhanced.     

The Understanding of Pans in 3- to 6-Year-Old Children

In this study, we examined the extent to which preschool children were able to understand pans (continuous sideward shifts of a scene generated by rotating the camera around a virtual axis), one of the most typical technical elements of films. This was done by showing 60 participating children a film in which a teddy bear asked them questions about pan sequences. The questions could be answered correctly only if the underlying pan was understood. The study revealed that the increase in the children's comprehension of the pans was significantly correlated with age and was facilitated by gains in visual working memory (VWM). It was found that VWM in 3 year olds is generally so low that they are still not able to understand any pan sequences. Most of the pans were understood by those children who could remember the locations of two simple objects. This VWM level is sex dependent and is usually reached by boys at age 4 and by girls at age 5; thus, boys understand pans quite a bit earlier. Perception speed, pan speed, and television consumption played rather limited roles. An appropriate model for the understanding of pans is subsequently introduced and discussed.     

Duration perception of emotional stimuli: Using evaluative conditioning to avoid sensory confounds

It has been found that emotional pictures are estimated to last longer than neutral ones. However, emotional and neutral stimuli often differ in their physical characteristics, too. Since this might also affect time perception, we present a method disentangling a possible confounding regarding the processing of physically different stimulus material. In the evaluative condition paradigm, participants, at first, learnt the association of neutral images with a certain Landolt ring and of emotional images with another Landolt ring with a different gap position. The conditioned Landolt rings were subsequently used in a temporal bisection task. In two experiments, the results revealed a temporal overestimation of Landolt rings conditioned with emotional pictures compared to neutral pictures showing that the temporal overestimation of emotional stimuli cannot be attributed to perceptual differences between neutral and emotional stimuli. The method provides the potential for investigating emotional effects on various perceptual processes.     

On the relations between crowding and visual masking

To study the question of which processes contribute to crowding and whether these are comparable to those of visual temporal masking, we varied the stimulus onset asynchrony (SOA) between target and flankers in a crowding setting. Monotonically increasing Type A masking functions observedfor small spacings and large eccentricities indicate that the integration of information from target and flankers underlies crowding. Decreasing masking functions obtained for large spacings and small eccentricities relate processes of crowding to those contributing to Type B masking. In addition, Type B masking was more frequent with letter-like nonletter flankers than with letter flankers, suggesting that Type B masking, just like crowding over large areas, is due to higher level interactions. The rapid decrease of the effects of interletter spacing and eccentricity with increasing SOA indicates that positional information is transient.
