A note on the normal form of closed formulas of interpretability logic

Each closed (i.e. variable free) formula of interpretability logic is equivalent in ILF to a closed formula of the provability logic G, thus to a Boolean combination of formulas of the form ⁿ.     

Induction of intellectual gains in blind children

Twenty blind children (5–10 years old) were taught the concept of seriation by a learning set procedure. Ten of the children were also taught a simple classification concept to see if developing both abilities would produce more general intellectual gains. Children in a control group had training sessions matched in timing and extent, but differing in content. The results indicate that mastery of the concepts of seriation and classification can be accelerated through training. Training also affected WISC and SIT IQ scores; for these measurements, the seriation-classification group showed the greatest increase. Training had no effect on measures of psychological and social adjustment. The findings suggest that learning set training of Piagetian concepts can be effective in overcoming some conceptual deficiencies found in blind children. It may be profitable to test similar procedures with other children who are biologically mature but lagging in conceptual development.     

When Reminiscence is Harmful: The Relationship Between Self-Negative Reminiscence Functions,Need Satisfaction,and Depressive Symptoms Among Elderly People from Cameroon,the Czech Republic,and Germany

Reminiscence has various functions, not all of which are beneficial for well-being. In particular, self-negative reminiscence functions—boredom reduction, bitterness revival, and intimacy maintenance—have been shown to be associated with reduced well-being. The present paper examines the link between self-negative reminiscence functions and depression in three cultural contexts. We hypothesize that both variables are indirectly linked via satisfaction of basic psychological needs: Self-negative reminiscing is associated with an impairment of need satisfaction which in turn relates to enhanced depressive symptoms. This hypothesis is tested in elderlies from Cameroon, the Czech Republic, and Germany. A total of 637 elderly participants reported on self-negative reminiscing, need satisfaction, and depressive symptoms. Analyses indicate that for boredom reduction and bitterness revival an indirect effect on depression via decreased need satisfaction can be established in all cultural contexts. For intimacy maintenance, a different picture emerges in that in the Czech and the German sample, there was a direct effect on depression but not an indirect one via need satisfaction. Yet, among Cameroonian participants an indirect effect was found, demonstrating that intimacy maintenance was related to decreased depression via enhanced need satisfaction. These results suggest that reminiscence functions may have partly universal, partly culture-specific effects on well-being.     

BONE MARROW TRANSPLANTATION IN A PATIENT WHO EXPERIENCED TORTURE IN A PRISONER OF WAR CAMP: NARCISSISM AND SURVIVAL

Post-traumatic stress disorder has been described as a syndrome from which an individual may suffer as a result of extraordinary trauma. Torture of prisoners of war in Serbian camps during the war in Croatia is just such a stressful situation that requires mobilization of all defense mechanisms of an individual. The authors present a case study of a former prisoner of war who acquired acute myelogenous leukemia several months after release and was treated with bone marrow transplantation. On release the patient was medically examined, like all prisoners of war, and the findings did not suggest any disease. Because of the situation, the patient was in psychotherapeutic observation and treatment after his illness was diagnosed and throughout the transplantation treatment.     

You Can Only Die Thrice: Death and Dying of a Human Body in Psychoanalytical Perspective

This paper compares the (cultural) necessity of death/dying, perceived as a sequence of Imaginary—Real—Symbolic, to Van Gennep’s three-staged rite of passage. If this logic is disrupted, the subject responsible necessitates attribution of special social status and can come to embody the imagery of a life worth living. This philosophical framework, which includes epistemologies borrowed from medical anthropology, demonstrates there is more for humans to lose than biological (Real) life; a far greater loss is to exist without (Symbolic) reason to live. A critique of prevalent quantitative methodology in assessing links between spirituality and the human body is added.     

Individual differences in the linguistic competence of referential and expressive subjects

The aim of this work was to examine individual differences in referential and expressive style through a longitudinal study. The composition of the first 50 words, communicative gestures, the conversational style of dyads and the percentage of vocabulary produced from 12 to 24 month-olds were analyzed. The vocabulary was collected through interviews to parents and sessions of mother-infant interaction in the laboratory. Significant differences in the proportion of common nouns and frozen phrases between referential and expressive children in the frequency of communicative gestures and style conversation were found. Thus, referential children and their mothers used more pointing gestures than the expressive children and their mothers. Additionally, mothers of referential children used completing more frequently.     

Identification of partially presented meaningless patterns: effect of completeness and distinctiveness

The role of parts versus that of wholes in a visual perception has been debated for a century as two opposite approaches, namely, an analytic and holistic. In two psychophysical experiments we investigated whether the stimulus completeness or distinctiveness is essential for identification of the partially presented patterns under brief presentation conditions. For this purpose, a special class of stimuli was constructed in such a way that the patterns could be divided into informative and redundant parts. The first experiment clearly demonstrated the importance of the redundant part for effective pattern identification for the majority of subjects. The second experiment revealed the direct dependence of identification accuracy of the patterns on their completeness (2, 3, 4, 5, or 6 elements). Familiarisation of subjects with the test stimuli influenced the strength of this dependence.     

Reciprocated and unreciprocated dyadic peer preferences and academic achievement of Israeli and immigrant students: a longitudinal study

The authors used a longitudinal design to investigate 2 major issues: first, whether popularity with classmates results in better academic achievement or academic achievement improves popularity with classmates; and second, how time affects in-group and out-group contacts in the elementary school. The authors studied these issues by means of an interactive measure of reciprocated and unreciprocated contacts with peers. This measure indicated the extent to which aspirations for close relations were fulfilled or not fulfilled by each member of a dyad. Participants were 305 fifth- and sixth-grade Israeli students and 100 immigrant classmates. Results indicated (a) higher academic achievement predicted higher numbers of bids for reciprocal contacts in class but not higher numbers of bids for contacts that were not reciprocated; (b) a higher level of unreciprocated bids for contact seemed to have a detrimental effect on academic performance; (c) teachers tended to rate as more adjusted to school the immigrant students who were willing to engage in more intensive reciprocated contacts with Israeli peers; and (d) reciprocated contacts tended to increase whereas unreciprocated contacts were inclined to decrease as a function of time. These changes over time were more prominent for the dominant hosts than for their migrant classmates.
