Schmerzmanagement bei fortgeschrittener Demenz

Typischerweise liegen bei geriatrischen Patienten mehrere Erkrankungen gleichzeitig vor, die sich wechselseitig in ihrem Verlauf, aber auch in ihrer symptomatischen Auswirkung, beeinflussen. Dies gilt besonders für Zusammentreffen chronischer Schmerzen mit einer Demenz.     

Current behavior modification in the classroom: be still, be quiet, be docile

Classrooms have recently been criticized as total institutions where there is a rigid preoccupation with order and control, and where children are required to be still, to be silent, and to obey. Behavior modification has been described as a major source of change in the classroom. A review of this journal's papers on behavior modification in the classroom indicated that inappropriate behavior has been consistently defined as behavior that interferes with order, quiet, and stillness. It is argued therefore, that behavior modification has supported rather than changed the questionable status quo. Alternative areas for behavior modification in traditional classrooms and the role of behavior modification in the development of open classrooms are discussed.     

The concept of auditory stimulus representation in cognitive neuroscience

The sequence of neurophysiological processes elicited in the auditory system by a sound is analyzed in search of the stage at which the processes carrying sensory information cross the borderline beyond which they directly underlie sound perception. Neurophysiological data suggest that this transition occurs when the sensory input is mapped onto the physiological basis of sensory memory in the auditory cortex. At this point, the sensory information carried by the stimulus-elicited process corresponds, for the first time, to that contained by the actual sound percept. Before this stage, the sensory stimulus code is fragmentary, lacks the time dimension, cannot enter conscious perception, and is not accessible to top-down processes (voluntary mental operations). On these grounds, 2 distinct stages of auditory sensory processing, prerepresentational and representational, can be distinguished.     

Abortion and victimisability

ABSTRACT This paper begins with a review of major difficulties with both extreme conservative and extreme liberal views on foetal moral status and the morality of abortion. There follows an outline and defence of a moderate position on abortion which is centred in an account of emergent foetal victimisability in being killed. Lastly, various perplexities about this view are explored, particularly the question whether, once victimisable at all, the victimisability of a foetus should reasonably be thought to increase proportionately with further biological development.     

Expert face coding: Configural and component coding of own-race and other-race faces

Configural and holistic coding are hallmarks of face perception. Although recent studies have shown that own-race faces are coded more holistically than other-race faces, the evidence for better configural coding of own-race faces is equivocal. We directly measured configural and component coding of own- and other-race male faces in Caucasian and Chinese participants. We manipulated individual features (components) or their spatial relations (configurations) using a novel morphing method to vary difficulty parametrically and tested sensitivity to these changes in a sequential matching task. Both configural and component coding were better for upright own-race than for upright other-race faces. Inversion impaired detection of configural changes more than it did detection of component changes, but also impaired performance more for easier discriminations,independent of type of change. These results challenge explanations of face expertise that rely solely on configural and holistic processing, and also call into question the widespread interpretation of large inversion decrements as diagnostic of configural coding.     

Communication Styles and Marital Satisfaction in Israeli and American Couples

This study examined the conflict-related communication styles of American and Israeli couples and how these communication styles related to marital satisfaction in the two groups. An Israeli sample was recruited from Israeli couples currently living in New York City; the American sample was selected from the friendship circles of the Israeli couples. In spite of the close social ties of the two groups, we predicted that the conflict-related communication styles of the Israelis would be less calm and rational than those of the Americans and that such rational modes of communication would be positively associated with marital satisfaction for the Americans but not for the Israelis. The principle instruments were Straus' Conflict Tactics Scale, Ryder's Imagined Situation Inventory, and Spanier's Dyadic Adjustment Scale. Results largely confirmed the hypotheses. Israeli couples were more apt to be verbally aggressive (but less physically violent) and less apt to behave calmly during marital conflict, but these communication styles did not relate to marital satisfaction as strongly for the Israelis as for the Americans. These findings are discussed as a demonstration of the importance of considering cultural context when treating families.     

Event-related brain potentials reflect traces of echoic memory in humans

In sequences of identical auditory stimuli, infrequent deviant stimuli elicit an event-related brain potential component called mismatch negativity (MMN). MMN is presumed to reflect the existence of a memory trace of the frequent stimulus at the moment of presentation of the infrequent stimulus. This hypothesis was tested by applying the recognition-masking paradigm of cognitive psychology. In this paradigm, a masking sound presented shortly before or after a test stimulus diminishes the recognition memory of this stimulus, the more so the shorter the interval between the test and masking stimuli. This interval was varied in the present study. It was found that the MMN amplitude strongly correlated with the subject’s ability to discriminate between frequent and infrequent stimuli. This result strongly suggests that MMN providesa measure for a trace of sensory memory, and further, that with MMN, this memory can be studied without performance-related distortions.     

Representing AIDS

AIDS has contributed to changes in how our society constructs its image of death. In the early 1980s Philippe Ariès argued that death and the symbols surrounding it had been “relegated to the secret, private space of the home or the hospital.” With the coming of AIDS, death demands its place in the public mind - and eye. Many artists have devoted their talents to making AIDS visible. In doing so, they have resurrected many questions about sexuality and mortality. This paper discusses several examples of current AIDS art and places them in a wider cultural and historical context.
