The influence of picture size on recognition and exploratory behaviour in raised-line drawings

We demonstrate the influence of picture size on haptic recognition and exploratory behaviour. The stimuli were raised-line drawings of everyday objects. Participants were instructed to think aloud during haptic exploration of the pictures. We measured the delay between initial correct speculation and final correct response. The results indicate that picture size influences accuracy but not response latency: large drawings are recognised more often but not faster. By analysing video recordings of the experiment we found that two-handed exploration increases when picture size increases and that, on average, 83% of the exploration time involves the use of two hands. The thinking-aloud data showed that the average time difference between the initial correct speculation and final correct response amounted to 23% of the total reaction time. We discuss our results with respect to the design of tactile aids and the ecological validity of single-finger exploration.     

Emotion and false memory: How goal-irrelevance can be relevant for what people remember

Elaborating on misleading information concerning emotional events can lead people to form false memories. The present experiment compared participants’ susceptibility to false memories when they elaborated on information associated with positive versus negative emotion and pregoal versus postgoal emotion. Pregoal emotion reflects appraisals that goal attainment or failure is anticipated but has not yet occurred (e.g., hope and fear). Postgoal emotion reflects appraisals that goal attainment or failure has already occurred (e.g., happiness and devastation). Participants watched a slideshow depicting an interaction between a couple and were asked to empathise with the protagonist's feelings of hope (positive pregoal), happiness (positive postgoal), fear (negative pregoal), or devastation (negative postgoal); in control conditions, no emotion was mentioned. Participants were then asked to reflect on details of the interaction that had occurred (true) or had not occurred (false), and that were relevant or irrelevant to the protagonist's goal. Irrespective of emotional valence, participants in the pregoal conditions were more susceptible to false memories concerning goal-irrelevant details than were participants in the other conditions. These findings support the view that pregoal emotions narrow attention to information relevant to goal pursuit, increasing susceptibility to false memories for irrelevant information.     

Contingency awareness in a symptom learning paradigm: necessary but not sufficient?

In previous studies, we found that bodily symptoms can be learned in a differential conditioning paradigm, using odors as conditioned stimuli (CSs) and CO2-enriched air as unconditioned stimulus (US). However, this only occurred when the odor CS had a negative valence (a selective conditioning effect), and tended to be more pronounced in persons scoring high for Negative Affectivity (NA). This paper considers the necessity and/or sufficiency of awareness of the CS-US contingency in three studies using this paradigm. The relation between contingency awareness and the selective conditioning effect, and between contingency awareness and NA was also considered. Both self reported symptoms and respiratory physiology served as dependent variables. A learning effect on symptoms was found only for participants aware of the CS-US contingency, but not all participants reporting contingency awareness showed a learning effect. No conditioning effects appeared on the physiological measures. Also contingency awareness did not account for the selective conditioning effect, and did not interact with NA. Overall, the necessity but insufficiency hypotheses can only be withhold for group data and not for individual data.     

Effects of visual center of pressure feedback on postural control in young and elderly healthy adults and in stroke patients

The goal of this study was to compare young and elderly healthy individuals and elderly stroke patients in their capacity to use visual CP feedback (VF) in controlling both quiet standing and weight shifting and to assess their sensory re-weighing when this VF is withdrawn. A total of 40 participants were involved in this study. Participants were asked to either quietly stand on a force platform for a period of 45 s with eyes open (EO), using visual feedback (VF) or without visual feedback (No VF) or to perform a dynamic weight shifting task while using VF or No VF. During the quiet standing trials with VF, only the young (YO) were able to decrease the amplitude and increase the frequency of their sway in either plane. Removal of the VF resulted in a 'destabilizing' effect in both healthy elderly (EL) and stroke patients (ST) in the sagittal plane. With regard to the dynamic task, both the YO and EL were generally more successful at weight shifting in terms of speed and control when compared to the ST. Yet, when VF was removed, only the YO were able to largely maintain speed and precision of control. Hence, providing or removing visual CP feedback during quiet standing or removing VF during visually controlled weight shifting can discriminate healthy young participants from healthy elderly, but does not clearly discriminate healthy elderly from stroke patients in the same age group. Results revealed that sagittal plane imbalance in healthy elderly and stroke patients may be largely due to the effects of aging, whereas frontal plane imbalance is much more specific for the postural problems associated with stroke.     

Dealing with Relational and Social Challenges After Child Soldiering: Perspectives of Formerly Recruited Youth and Their Communities in Northern Uganda

The reintegration of formerly recruited youth typically engenders a range of relational and social challenges, affecting both formerly recruited youth and the communities to which they return. Yet, research rarely studies the perspectives of community members, hampering the design of much‐needed community‐based interventions. This study aimed to understand how communities in northern Uganda experience and deal with relational and social challenges during the reintegration of youths who were formerly recruited into the Lord's resistance army (LRA). The study was undertaken in 2012 in Lira district. Participatory Ranking Methodology (PRM) was conducted with 267 participants, of whom 49 were formerly recruited youths. The results show five themes that give insight into how communities experience and handle relational and social challenges in the reintegration of formerly recruited youth: (i) letting go of fear, (ii) getting used to life after captivity, (iii) resentment and forgiveness, (iv) reducing insults and nicknaming and (v) coping with ongoing relational and social challenges. We discuss how formerly recruited youths and other community members frame relational and social challenges differently, and value similar resources for different reasons. The results of this study suggest that multiple experiences of and perspectives on relational and social challenges following child soldiering should be taken into account to develop interventions that are supported and valued by the community. Furthermore, interventions should draw upon the strategies that communities have already developed in response to relational and social challenges. Copyright © 2015 John Wiley & Sons, Ltd.     

From psychotherapy to psychoanalysis: Frederik van Eeden and Albert Willem van Renterghem

At the end of the nineteenth century, the unconscious was discovered by various students of the human mind. No agreement existed, however, about its nature–whether it represented the seat of the abnormal, the supranormal, or both. Frederik van Eeden (1860–1932), better known as a writer than as a physician, and Albert Willem van Renterghem (1846–1939), a country doctor, were both attracted by the philosophy of psychic monism and were disappointed by official medical science. They felt that that the mind played a greater role in curing and healing than official medicine could acknowledge. Van Eeden, a socialist, moved away from medical science. Fascinated by psychical research, he embraced Spiritualism and joined the Roman Catholic Church. His attitude toward psychoanalysis was ambivalent. Van Renterghem, by contrast, became a respected and well-to-do psychiatrist, and was one of the first Dutch physicians to embrace psychoanalysis. This study of two Dutch psychiatrists shows on the one hand that only gradually the mystically tinged soul of the first dynamic psychiatry became the conscious and unconscious mind of depth psychology, and on the other hand that the reception of psychoanalysis was furthered by the prevailing interest in mysticism.     

Illness-specific catastrophic thinking and overperception in asthma.

OBJECTIVE: This study investigated the role of illness-specific catastrophic thinking in symptom perception in asthma. DESIGN AND MAIN OUTCOME MEASURES: A total sample of 72 patients with intermittent to moderate persistent asthma completed the Catastrophizing about Asthma Scale and completed the Asthma Symptom Checklist to measure retrospective symptom reporting. In addition, symptoms were concurrently assessed during different respiratory challenges eliciting mild and ambiguous versus salient and pronounced symptoms. RESULTS: Catastrophic thinking in general, when patients are not having an exacerbation, is related to an increase in emotional symptoms, especially in ambiguous situations where respiratory difficulties could occur. Catastrophic thinking during exacerbations is related to an increase in emotional symptoms as well as in respiratory symptoms during respiratory challenges. CONCLUSION: These strong relationships between catastrophic thinking and increased perception of asthma symptoms suggest a link between illness-specific catastrophic thinking and overperception. Consequently, catastrophic thoughts are an important target for psychological interventions in support of drug treatment.
