Roles of egocentric and allocentric spatial representations in locomotion and reorientation

Four experiments investigated the nature of spatial representations used in locomotion. Participants learned the layout of several objects and then pointed to the objects while blindfolded in 3 conditions: before turning (baseline), after turning to a new heading (updating), and after disorientation (disorientation). The internal consistency of pointing in the disorientation condition was relatively high and equivalent to that in the baseline and updating conditions, when the layout had salient intrinsic axes and the participants learned the locations of the objects on the periphery of the layout. The internal consistency of pointing was disrupted by disorientation when participants learned the locations of objects while standing amid them and the layout did not have salient intrinsic axes. It was also observed that many participants retrieved spatial relations after disorientation from the original learning heading. These results indicate that people form an allocentric representation of object-to-object spatial relations when they learn the layout of a novel environment and use that representation to locate objects around them. Egocentric representations may be used to locate objects when allocentric representations are not of high fidelity.     

Analogical reasoning in handling emerging technologies: the case of umbilical cord blood biobanking

How are we individually and as a society to handle new and emerging technologies? This challenging question underlies much of the bioethical debates of modern times. To address this question we need suitable conceptions of the new technology and ways of identifying its proper management and regulation. To establish conceptions and to find ways to handle emerging technologies we tend to use analogies extensively. The aim of this article is to investigate the role that analogies play or may play in the processes of understanding and managing new technology. More precisely we aim to unveil the role of analogies as analytical devices in exploring the "being" of the new technology as well the normative function of analogies in conceptualizing the characteristics and applications of new technology. Umbilical cord blood biobanking will be used as a case to investigate these roles and functions.     

Validation of distinct amnesic and executive type memory deficit in a psychiatric sample based on retrieval performance

Studies of localized brain dysfunctions have revealed connections between patterns of cognitive dysfunction and specific profiles of memory impairment. The amnesic type of memory impairment is defined by deficits in both free recall and recognition memory, whereas the dysexecutive memory impairment is characterized by retrieval deficits, i.e. a disproportional impairment in free recall relative to recognition memory. The present study tests whether classifications of psychiatric patients into recall impaired only (= RO group) and Recall and Recognition impaired (= RR group) correspond to the executive type and amnesic type of memory impairment. The alternative hypothesis is that the two groups merely differ in degree of neuropsychological and psychiatric disturbance. Forty-four subjects impaired on California Verbal Learning Test (CVLT) were selected from a larger database of 103 impaired and non-impaired subjects with schizophrenia or recurrent major depression. Subjects were classified into RO and RR groups and compared on measures of memory strategy (recency effect and interference on CVLT), overall neuropsychological function (Stroop Test and WAIS-R similarity) and psychiatric symptom load (positive and negative symptoms). Repeated measures ANOVA showed no effects of group, i.e. the RR group did not perform consistently below the RO group with regard to memory strategy, neuropsychological function or psychiatric symptom load. Two out of three analyses showed group x test interaction, supporting the dissociation of distinct executive and amnesic profiles among psychiatric patients. The RO group was more susceptible to interference but had better recency score than the RR group. The RO had higher negative symptoms while the RR group had higher positive symptoms.     

THE ATTRACTIVENESS OF UNCERTAINTY

Problem solving tasks of different informational content were presented for free choice, and the attractiveness of the situation was measured by repeated ratings. The hypothesis of an inverted U-shaped relationship between uncertainty and attractiveness of the situation was supported. The value of rating as a method for this purpose, and some results indicating the importance of stimulus patterning are discussed.     

Chain of Care for Patients with Intentional Self‐Harm: An Effective Strategy to Reduce Suicide Rates?

Chain of care for patients with intentional self‐harm was important in the Norwegian national action plan to prevent suicide. In this study there were two aims: (1) to calculate the potential effects of chain of care on reducing suicide rates, and (2) to assess whether suicide rates decreased more in areas where chain of care had been implemented than in other areas. We observed no differences in changes in suicide rates between areas with and without the intervention. The calculated potential effects of chain of care on national suicide rates were very small, even under unrealistically favorable conditions.     

Has infantile sexuality anything to do with infants?

Classical psychoanalytic theory draws many concepts from mental processes that are assumed to arise in the infant and influence the adult mind. Still, psychoanalytic practice with mothers and infants has been integrated but little within general psychoanalytic theory. One reason is that only few analysts have utilized such practice to further theory. Another reason is that infant therapists tend to abandon classical psychoanalytic concepts in favour of attachment concepts. As a result the concept of infantile sexuality, so central to classical theory, plays an unobtrusive role in clinical discussions on infant therapy. The author argues that infantile sexuality plays an important role in many mother-infant disturbances. To function as a clinical concept, it needs to be delineated from attachment and be understood in the context of mother-infant interaction. Two examples are provided; one where the analyst's infantile sexuality emerged in a comment to the infant. Another is a case of breast-feeding problems with a little boy fretting at the breast. This is interpreted as reflecting the mother's infantile sexual conflicts as well as the boy's emerging internalization of them. Thus, to conceptualize such disorders we need to take into account the infantile sexuality in both mother and baby.     

Psychoanalytic case presentations in a weaving thoughts group: On countertransference and group dynamics

This article summarizes experiences of psychoanalytic case presentations in weaving thoughts (WT) peer groups. The format is presented and illustrated using a session with a group of analysts. In this setting, the frame of the presentation is guaranteed by the moderator. One aim is to create a group setting with many parallels to the analytic situation. A second aim is to discourage members from becoming enmeshed in destructive group functioning, such as internal disputes that may block a deeper understanding of the material. Classical psychoanalysis permits the analyst to reflect behind the patient on the transference-countertransference interplay. However, such reflections may be marred by undetected countertransference problems. Different supervision formats have different ways of helping the analyst with them. The WT format 'copies' the analytic session to the group, hence each member associates to the material in peace. Meanwhile the presenter looks, metaphorically speaking, at the web of their associations at his or her own pace. This may help him or her to confront and reflect on unresolved countertransference issues. This article indicates the method's similarities and differences compared with other formats. Arguments are supported by a child psychotherapy session, but the method is equally suitable for adult case material.     

Object processing in visual perception and action in children and adults

We investigated whether 6- and 7-year-olds and 9- and 10-year-olds, as well as adults, process object dimensions independent of or in interaction with one another in a perception and action task by adapting Ganel and Goodale's method for testing adults (Nature, 2003, Vol. 426, pp. 664-667). In addition, we aimed to confirm Ganel and Goodale's results in adults to reliably compare their processing strategies with those of children. Specifically, we tested the abilities of children and adults to perceptually classify (perception task) or grasp (action task) the width of a rectangular object while ignoring its length. We found that adults process object dimensions in interaction with one another in visual perception but independent of each other in action, thereby replicating Ganel and Goodale's results. Children processed object dimensions interactively in visual perception, and there was also some evidence for interactive processing in action. Possible reasons for these differences in object processing between children and adults are discussed.     

Regulatory competence and social communication in term and preterm infants at 12 months corrected age. Results from a randomized controlled trial

Temperamental regulatory competence and social communication in term and preterm infants at 12 months corrected age was studied in a randomized controlled intervention trial aimed at enhancing maternal sensitive responsiveness. Surviving infants <2000 g from a geographically defined area were randomized to an intervention (71) or a control group (69), and compared with term infants (74). The intervention was a modified version of the "Mother-Infant Transaction Program". Regulatory competence was measured with the Infant Behavior Questionnaire, and social communication with the Early Social Communication Scales. Preterm intervention infants with low regulatory competence had higher responding to joint attention than preterm control infants. A sensitizing intervention may moderate the association between temperament and social communication, and thus allow an alternative functional outlet for preterm infants low in regulatory competence. The finding may have implications for conceptualizations of the role of early sensitizing interventions in promoting important developmental outcomes for premature infants.
