Remembering 1500 pictures: the right hemisphere remembers better than the left

We hypothesized that the right hemisphere would be superior to the left hemisphere in remembering having seen a specific picture before, given its superiority in perceptually encoding specific aspects of visual form. A large set of pictures (N=1500) of animals, human faces, artifacts, landscapes, and art paintings were shown for 2s in central vision, or tachistoscopically (for 100ms) in each half visual field, to normal participants who were then tested 1-6 days later for their recognition. Images that were presented initially to the right hemisphere were better recognized than those presented to the left hemisphere. These results, obtained with participants with intact brains, large number of stimuli, and long retention delays, are consistent with previously described hemispheric differences in the memory of split-brain patients.     

医学伦理学——欧洲与中国的桥

跨文化医学伦理学研究,要求我们以理智的方式去应对全球化。既要维护多样性,又要明确共同利益、亦要追求共同目标。任何文化都不能强行提出一些标准去规范国际间的生物医学。自主权应坚持义务论的解释,否则一个强势风气将会支配利益的选择解释,将文化多样性在伦理学中铸成一个统一的模式,形成自主权的“通货膨胀倾向”。     

Dispositional aspects of body focus and idiopathic environmental intolerance attributed to electromagnetic fields (IEI‐EMF)

Body focus is often considered an undesirable characteristic from medical point of view as it amplifies symptoms and leads to higher levels of health anxiety. However, it is connected to mindfulness, well‐being and the sense of self in psychotherapy. The current study aimed to investigate the contribution of various body focus related constructs to acute and chronic generation and maintenance of medically unexplained symptoms (MUS). Thirty‐six individuals with idiopathic environmental intolerance to electromagnetic fields (IEI‐EMF) and 36 controls were asked to complete questionnaires assessing negative affect, worries about harmful effects of EMFs, health anxiety (HA), body awareness, and somatosensory amplification (SSA), and to report experienced symptoms evoked by a sham magnetic field. Body awareness, HA, SSA, and EMF‐related worries showed good discriminative power between individuals with IEI‐EMF and controls. Considering all variables together, SSA was the best predictor of IEI‐EMF. In the believed presence of a MF, people with IEI‐EMF showed higher levels of anxiety and reported more symptoms than controls. In the IEI‐EMF group, actual symptom reports were predicted by HA and state anxiety, while a reverse relationship between symptom reports and HA was found in the control group. Our findings show that SSA is a particularly important contributor to IEI‐EMF, probably because it is the most comprehensive factor in its aetiology. IEI‐EMF is associated with both a fear‐related monitoring of bodily symptoms and a non‐evaluative body focus. The identification of dispositional body focus may be relevant for the management of MUS.     

Empirical Conditions for a Reidean Geometry of Visual Experience

Thomas Reid’s Geometry of Visibles, according to which the geometrical properties of an object’s perspectival appearance equal the geometrical properties of its projection on the inside of a sphere with the eye in its centre allows for two different interpretations. It may (1) be understood as a theory about phenomenal visual space—i.e. an account of how things appear to human observers from a certain point of view—or it may (2) be seen as a mathematical model of viewpoint-relative but mind-independent relational properties of objects. This paper makes a systematic and a historical claim. I shall argue, first, that given certain features of the human visual system phenomenal visual space differs in several aspects from Reidean visual space. Secondly, I suggest that, since Reid was aware of some of these empirical facts, we should interpret Reid as endorsing the second interpretation of the Geometry of Visibles.     

Assessing the Level of Structural Integration Using Operationalized Psychodynamic Diagnosis (OPD): Implications for DSM–5

In order to investigate the state-trait anxiety distinction in emotionally disturbed and normal children, the responses of 120 emotionally disturbed children and 126 normal children to the State-Trait Anxiety Inventory for Children (Spielberger, 1973) were factor analyzed separately. For the emotionally disturbed group two A-State and two A-Trait factors were found with the A-State factors accounting for significantly more of the variance than did A-Trait factors. For the normal group four A-State and two A-Trait factors were found, but there was not a significant difference between the amount of variance accounted for by A-State and A-Trait factors. Results were discussed as supporting the state-trait distinction and as having several implications for future research on anxiety.     

The Ways of Humans: The Emergence of Sense and Common Sense Through Language Production

The present paper is an extension of Elstrup (Integrative Psychological and Behavioral Science, doi:10.1007/s12124-009-9095-x, 2009). Primarily, it is argued that the model presented in ‘The ways of humans’ describes the functional foundation of an emergent hierarchy and therefore cannot be reduced to its elements. Next, some ideas concerning the language mechanism, sense making and common sense are developed. Finally, it is argued that the scientific exploration of human development needs a unit of measurement. It is suggested that this unit can be found in time dependent sense making.     

Sleep directly following learning benefits consolidation of spatial associative memory

The last decade has brought forth convincing evidence for a role of sleep in non-declarative memory. A similar function of sleep in episodic memory is supported by various correlational studies, but direct evidence is limited. Here we show that cued recall of face-location associations is significantly higher following a 12-h retention interval containing sleep than following an equally long period of waking. Furthermore, retention is significantly higher over a 24-h sleep-wake interval than over an equally long wake-sleep interval. This difference occurs because retention during sleep was significantly better when sleep followed learning directly, rather than after a day of waking. These data demonstrate a beneficial effect of sleep on memory that cannot be explained solely as a consequence of reduced interference. Rather, our findings suggest a competitive consolidation process, in which the fate of a memory depends, at least in part, on its relative stability at sleep onset: Strong memories tend to be preserved, while weaker memories erode still further. An important aspect of memory consolidation may thus result from the removal of irrelevant memory "debris."     

The Ways of Humans: Modelling the Fundamentals of Psychology and Social Relations

The present paper comprises a set of theoretical suppositions concerning three major subjects: the fundamentals of psychology (psycho-logics), the fundamentals of sociology (socio-logics) and the relationship between psycho-logics and socio-logics. First, it is argued that intentionality is the founding unit of psychology. On the basis of this supposition, three phylogenetic steps: sense, mind, and consciousness are identified and modelled. Subsequently it is argued that sociology builds upon five and only five fundamental types of relations: competition, transference, coordination, dependence and control. It is stated that any sociological network is composed by sets of these relations. Finally it is argued that psychology and sociology form a complex micro macro system in which psychological processes give rise to sociological networks that in turn constrain psychological processes.     

Irrationality as a Selfdefeating Calue-Orientation: A further study of the SVO-12 scale

The SVO-12 is based on an emotive approach to the assessment of irrationality. In order to test its reliability and validity the scale was administered to a group of students and a group of psychiatric patients. The statistical analyses gave acceptable reliability coefficients in both groups. Furthermore the scale differentiated significantly between patients and students, both totally and for men and women separately, thus supporting its validity according to RET-theory.and maintains a small private practice in Laksevåg, Bergen, Norway.
