Computers,information and ethics: A review of issues and literature

Editorial note:The following bibliographic survey of computer ethics is intended as a general introduction useful to guide both preliminary research and course development. It is the first of a series that Carl Mitcham will be doing on a number of specific discussions of ethics in science and technology. Future installments are projected on nuclear ethics, engineering ethics, ethics in scientific research, and biomedical ethics. With this [book] I issue “a call to arms.” The world needs much more discussion and writing on the social and ethical issues surrounding computing. I hope readers .... will take up the challenge.     

The Absurd Sensibility of Existential Psychotherapy: Clinical Application of Survivors' Experience of Treblinka and Other Death Camps

A pragmatic existential therapy was developed to help patients stuck in intractable life situations make the psychic turn of death camp survivors who learned to adapt to savage conditions in extremity. Using a model of absurd heroism inimical to therapies seeking to modify intrapsychic dynamics, this hardminded intervention thematizes (a) the clinical activation of biological intelligence; (b) reconciliation with the existential situation; (c) problem-solving; (d) therapeutic shaping of realistic, life-affirming attitudes; and (e) absurd happiness. Phenomenological evidence of the survivors' existential posture is drawn from death camp literature, while a comparative case application features a patient afflicted with neurofibromatosis.

SOME EFFECTS OF REINFORCEMENT SCHEDULES IN TEACHING PICTURE NAMES TO RETARDED CHILDREN1

The effects of several different schedules of primary reinforcement were compared in a picture-naming task with retarded children. In Experiment I, number of correct responses and learning rate were higher under fixed-ratio schedules than under continuous reinforcement. In Experiment II, number of correct responses and learning rate tended to be greater under intermediate than under low or high fixed-ratio schedules. In Experiment III, number of correct responses was higher under interlocking schedules, in which the response requirement increased with time following the previous reinforcement, than under comparable fixed-ratio schedules. Learning rates were generally low and, perhaps because of this, not very different under the two types of schedules in this experiment. Accuracy (i.e., proportion of trials on which correct responses occurred) was typically high and insensitive to variations in schedule and schedule parameter throughout each experiment.     

Effect of conflict between the body parts on perceptual adaptation

Two groups of subjects adapted to prismatic displacement. One adapted in a visual target condition, in which they pointed to an external visual target with their right index fingers. The other adapted in a body target condition, in which they pointed to their left index fingers with their right index fingers. The visual target group showed more adaptation of the right hand and less adaptation of the left hand than did the body target group. These results are consistent with an assimilation tendency within the proprioceptive modality, namely that body parts that are in contact tend to be perceived as occupying the same spatial position.     

The detection and treatment of artifacts in computer-controlled neurophysiological experiments

Pattern recognition algorithms may be employed on time-series data obtained in electrophysiological experiments to detect particular artifacts that would otherwise contaminate the experimental data. Such algorithms may be classified by the statistical properties of the data they test. Four representative algorithms are presented that, on the basis of prior experiments in our laboratory, perform satisfactorily to improve the quality of electrophysiological measurement.
