Cultures in CollisionPhilosophical Lessons from Computer-Mediated Communication

I expand the metaphor of computing as philosophical laboratory by exploring philosophical insights gleaned from examining computer-mediated communication (CMC) technologies in terms of the cultural values and communicative preferences they embed, as well as their interactions with the values and preferences that define diverse cultures in which the technologies are deployed. These empirically grounded data provide new insights for debates in philosophy of technology, notions of the self, and epistemology. This approach to utilizing data drawn from the cultural encounters facilitated by CMC technologies further suggests more ambitious ways of making philosophical use of CMC venues as a laboratory for testing and refining basic claims and hypotheses. The approach also uncovers other grounds that should encourage philosophers to become interdisciplinarians – not only for the sake of perhaps developing new sorts of insights and even forms of knowledge but also in order to shape and contribute to a global ethic and a Socratic education needed to sustain cultural diversity as CMC envelops the globe.     

Chaos, Communications Theory, and God's Abundance

As the creator, God is the source of the abundance for immense variety manifest in creation. The reservoir for this abundance is the primordial chaos, identified as the Pandemonium Tremendum. God manages this inexhaustible “storehouse of the snow” through decisions or “willings,” giving rise to constraints that result in the ordered array of creation. Without this active and decisive vigilance, the Pandemonium Tremendum would scour and ravage the creation. Also, as an omniscient, unobtrusive, and impartial witness, God manages the primordial chaos without compromising its unfettered variety. What is the role of chaos as the Ungrund? All creatures are the consequence of acts of decision. God alone is self‐decisive and, hence, the uniquely sovereign creator. That is, God arises spontaneously through an aboriginal act of in–speaking. Otherwise, and in utter contradiction to its radically unprincipled character, the primordial chaos would provide the arche or sufficient reason for divine causation. This mythic and metaphysical account falls in the tradition of Meister Eckhart and Nicolas Berdyaev and is expressed in the rubric of communication theory.     

Social Capital and Organizational Commitment

Organizational scientists have been investigating the role of human relationships vis-à-vis firm productivity for some years. Recently, Social Capital has been theorized to play a central part in the reduction of organizational transaction costs. We briefly position Social Capital among several theories claiming a role for interpersonal capital, review its theoretical nuances, and test this theoretical structure using a sample of 469 sales professionals from a leading medical services firm. Our findings indicate that trust, communication, and employee focus have significant direct and moderate indirect affects on organizational commitment.

Are readers of our face readers of our minds? Dogs (<Emphasis Type="Italic">Canis familiaris</Emphasis>) show situation-dependent recognition of human’s attention

The ability of animals to use behavioral/facial cues in detection of human attention has been widely investigated. In this test series we studied the ability of dogs to recognize human attention in different experimental situations (ball-fetching game, fetching objects on command, begging from humans). The attentional state of the humans was varied along two variables: (1) facing versus not facing the dog; (2) visible versus non-visible eyes. In the first set of experiments (fetching) the owners were told to take up different body positions (facing or not facing the dog) and to either cover or not cover their eyes with a blindfold. In the second set of experiments (begging) dogs had to choose between two eating humans based on either the visibility of the eyes or direction of the face. Our results show that the efficiency of dogs to discriminate between attentive and inattentive humans depended on the context of the test, but they could rely on the orientation of the body, the orientation of the head and the visibility of the eyes. With the exception of the fetching-game situation, they brought the object to the front of the human (even if he/she turned his/her back towards the dog), and preferentially begged from the facing (or seeing) human. There were also indications that dogs were sensitive to the visibility of the eyes because they showed increased hesitative behavior when approaching a blindfolded owner, and they also preferred to beg from the person with visible eyes. We conclude that dogs are able to rely on the same set of human facial cues for detection of attention, which form the behavioral basis of understanding attention in humans. Showing the ability of recognizing human attention across different situations dogs proved to be more flexible than chimpanzees investigated in similar circumstances.     

Problem solving skills in young yellow-crowned parakeets (Cyanoramphus auriceps)

Despite the long divergent evolutionary history of birds and mammals, early avian and primate cognitive development have many convergent features. Some of these features were investigated with a series of tasks designed to assess human infant development. The tasks were presented to young parakeets to assess their means-end problem solving abilities. Examples of these early skills are: attaining and playing with objects, retrieving rewards through use of a stick or rake, or by pulling in rewards on supports or on the ends of strings. Twelve such tasks were presented to 11 young yellow-crowned parakeets (Cyanoramphus auriceps) to investigate their natural abilities; there was no attempt to train them to do those tasks that they did not spontaneously perform. Six of the birds were parent-raised and five were hand-raised. The birds completed 9 of the 12 tasks, demonstrating all the Piagetian sensorimotor circular reactions, but they failed to hand-watch ("claw-watch"), to stack objects, or to fill a container. Their ordinality on the tasks differed from that of human infants in that locomotion to obtain objects occurred earlier in the avian sequence of development and the mid-level tasks were performed by the two groups of avian subjects in a mixed order perhaps indicating that these abilities may not emerge in any particular order for these birds as they supposedly do for human infants. The hand-raised group needed fewer sessions to complete these means-end tasks. Electronic Publication     

The painter and the cameraman: boundaries in clinical relationships

The issue of boundaries in clinician–patientencounters is considered through narrativeanalysis of four clinical stories in whichboundaries crossings are a self-conscioustopic. One story is by a physician as patient,two are by physicians, and one is by apalliative care nurse. The stories arediscussed using Walter Benjamin's distinctionbetween the painter, who maintains distance andsees the whole, and the cameraman, who usestechnology to penetrate realities and thenreassembles fragments. The essay argues thatdistance and closeness are ethical issues thatconstitute the possibility of clinicalencounters but the encounter also changes theclinician's sense of boundaries. The relevantethics of boundary decisions in most clinicalencounters are not procedural ethics but anethics of self-creation: in orienting toboundaries as doctors do, they createthemselves in their relations to others.     

Using the picture exchange communication system (PECS) with children with autism: assessment of PECS acquisition,speech, social-communicative behavior,and problem behavior

The picture exchange communication system (PECS) is an augmentative communication system frequently used with children with autism (Bondy & Frost, 1994; Siegel, 2000; Yamall, 2000). Despite its common clinical use, no well-controlled empirical investigations have been conducted to test the effectiveness of PECS. Using a multiple baseline design, the present study examined the acquisition of PECS with 3 children with autism. In addition, the study examined the effects of PECS training on the emergence of speech in play and academic settings. Ancillary measures of social-communicative behaviors and problem behaviors were recorded. Results indicated that all 3 children met the learning criterion for PECS and showed concomitant increases in verbal speech. Ancillary gains were associated with increases in social-communicative behaviors and decreases in problem behaviors. The results are discussed in terms of the provision of empirical support for PECS as well as the concomitant positive side effects of its use.     

Reinforcement magnitude and responding during treatment with differential reinforcement

Basic findings indicate that the amount or magnitude of reinforcement can influence free-operant responding prior to and during extinction. In this study, the relation between reinforcement magnitude and adaptive behavior was evaluated with 3 children as part of treatment with differential reinforcement. In the first experiment, a communicative response was shaped and maintained by the same reinforcer that was found to maintain problem behavior. Two reinforcement magnitudes (20-s or 60-s access to toys or escape from demands) were compared and found to be associated with similar levels of resistance to extinction. The relation between reinforcement magnitude and response maintenance was further evaluated in the second experiment by exposing the communicative response to 20-s or 300-s access to toys or escape. Results for 2 participants suggested that this factor may alter the duration of postreinforcement pauses.     

Competition between noncontingent and contingent reinforcement schedules during response acquisition

We examined the extent to which noncontingent reinforcement (NCR), when used as treatment to reduce problem behavior, might interfere with differential reinforcement contingencies designed to strengthen alternative behavior. After conducting a functional analysis to identify the reinforcers maintaining 2 participants' self-injurious behavior (SIB), we delivered those reinforcers under dense NCR schedules. We delivered the same reinforcers concurrently under differential-reinforcement-of-alternative-behavior (DRA) contingencies in an attempt to strengthen replacement behaviors (mands). Results showed that the NCR plus DRA intervention was associated with a decrease in SIB but little or no increase in appropriate mands. In a subsequent phase, when the NCR schedule was thinned while the DRA schedule remained unchanged, SIB remained low and mands increased. These results suggest that dense NCR schedules may alter establishing operations that result in not only suppression of problem behavior but also interference with the acquisition of appropriate behavior. Thus, the strengthening of socially appropriate behaviors as replacements for problem behavior during NCR interventions might best be achieved if the NCR schedule is first thinned.
