Influence of linguistic complexity,rate of presentation,and interphrase pause time on auditory-verbal comprehension of adult aphasic patients

Among the variables affecting comprehension of linguistic stimuli by aphasic subjects are syntactic complexity and processing time. Comprehension performance of 15 aphasic adults was studied while altering the rate of speech presentation and varying the pause time between the major phrases within sentences of increasing grammatical complexity.Simple Active Affirmative Declarative Sentences, Negative, and Passive sentences were presented (1) at the rate of 150 words per minute (wpm) with 1-sec interphrase pause time (IPT); (2) 150 wpm with no pauses; (3) 120 wpm with 1-sec IPT; (4) 120 wpm with no pauses added.Performance was seen to vary with increasing syntactical complexity and as a function of processing time. Greater comprehension was seen with active affirmative than negative; greater with passive affirmative than with active negative. Clinical implications are discussed. Subjects demonstrated greater comprehension when sentences were presented at slower than normal rate; addition of interphrase pause time intervals aided comprehension. Combining slower rate of presentation and IPT intervals provided greatest increase in auditory processing time and showed concomitant increase in comprehension performance.     

Catholic Feminist Ethics Reconsidered

Taking Catholic sexual ethics and liberal feminist ethics as points of departure, this essay argues that both frameworks are ill‐prepared to deal with the moral problems raised by sex trafficking: while Catholic sexual ethics is grounded in a normative understanding of sexuality, liberal feminist ethics argues for women's sexual autonomy, resting upon freedom of action and consent. From a perspective that attends both to the phenomenological interpretation of embodied selves and the Kantian normative interpretation of dignity, it becomes possible to critique both the Catholic and the liberal feminist frameworks of ethics. I argue that Catholic sexual ethics requires a reconceptualization as social ethics in order to meet the challenges of our present time, but that the shift is possible without giving up the moral imperatives of both Catholic and feminist ethics to protect human dignity and women's rights.     

Culture of distracted driving among intra-city commercial bus drivers in Ile-Ife,South-western Nigeria

This study investigated the culture of driving distractions among commercial bus drivers in Ile-Ife, Southwestern Nigeria. The aim was to identify the most prominent non-driving activity (N-DA) causing distraction to drivers. 16 independent research assistants were engaged in naturalistic recording of 128 commercial bus drivers in the study area. Among the variables selected for observation, passenger scouting (93%), fare collection (89.8%) and money counting (75%) were found to be the frequent N-DAs in their order of importance. These variables (passenger scouting, fare collection and money counting), however, have correlations with drivers having no conductor on-board. More so, relationships existed between certain N-DAs (call making, passenger scouting, fare collection sight-seeing and money counting) and loss of concentration by drivers on one hand; and between loss of concentration and the forms the loss of concentration took. It can be concluded from the findings that driving was disrupted and uncoordinated when combined with non-driving activities.     

CATHOLIC ETHICS AS SEEN FROM PADUA

During the summer of 2006, over four hundred Catholic ethicists from around the world gathered for four days in Padua, Italy. About sixty of the conference papers have become available in two edited collections, Catholic Theological Ethics in the World Church: The Plenary Papers from the First Cross‐cultural Conference on Catholic Theological Ethics, and Applied Ethics in a World Church: The Padua Conference. As the conference was marked by a distinctive and creative tension—between the diversity which characterized the nationalities and cultural identities of the participants, on the one hand, and the commonness of their religious heritage, on the other—these essays can tell us much about contemporary Catholic ethics in its response to global pluralism. The following develops four reflections. First, the conference papers pursue a style of scholarship that is at once critically creative and ecclesially rooted. Second, the conference raises new concerns about the importance that Christian formation must have in a pluralist world. Third, the participants affirm and defend the ultimate universality of moral goods while also arguing that these goods are expressed and embodied in unavoidably particular ways. Finally, the most important contribution that Catholic ethics can make to public conversations about issues of common concern is through its articulation and defense of key human values.

Synapses,Schizophrenia, and Civilization: What Made Homo Sapient?

Progress in technology has allowed dynamic research on the development of the human brain that has revolutionized concepts. Particularly, the notions of plasticity, neuronal selection, and the effects of afferent stimuli have entered into thinking about brain development. Here I focus on development from the age of four years to early adulthood, during which a 30 percent reduction in some brain synapses occurs that is out of proportion to changes in neuronal numbers. This corresponds temporally with changes in normal child behavior from the loose‐associative, almost schizoid, thinking and art of the four‐year‐old to the more trained, or disciplined, or acculturated—and restrained—personality of the young adult. I propose that the synaptic changes can best be thought of as a winnowing process likely subject to environmental influences. Acquisition of language and the ability to link linguistic cognition to the plastic development of the brain provide a potentially powerful means of explaining the evolutionally explosive development of human cognition and culture. Schizophrenia, a disease that can be envisioned as representing a derangement of synaptic maturation, may provide an entry into the search for genes controlling the processes mediating the unprecedented development of Homo sapiens over the past 40,000 to 70,000 years. The recently completed mapping of the genome of the chimpanzee provides a new frame of reference that may speed the search.     

PEIRCE'S PRAGMATIC THEOLOGY AND STOIC RELIGIOUS ETHICS1

Charles S. Peirce believed that his pragmatic philosophy could reconcile religion and science and that this reconciliation involves a religious ethics creating a real community with the cosmos and God. After some rival pragmatic approaches to God and religious belief inconsistent with Peirce's philosophy are set aside, his metaphysical plan for a reconciliation of religion and science is outlined. A panentheistic God makes the best match with his desired conclusions from the Neglected Argument for the reality of God, and this God is also capable of fulfilling the pragmatic role demanded by Peirce's ethical expectations for the intelligent functioning of religion. The discussion proceeds to an elaboration of the aesthetic, metaphysical, and ethical elements of Peirce's philosophical system, which indicate why Peirce's religious ethics is best categorized as akin to Stoicism, with some Christian elements. For Peirce, religious ethics proceeds from the (potentially universal) agapic community's cooperation with God's loving creativity of the universe.     

Infants’ behavioral styles in joint attention situations and parents’ socio-economic status

In this study the eco-cultural model of parenting (Keller, H. (2007). Cultures of infancy. Mahwah, NJ: Erlbaum) was applied to the study of joint attention behavior of children from families with different socio-economic status (SES). It was hypothesized that infants’ early communication styles would differ with SES reflecting more independent or interdependent interactions with their caregivers. It was also hypothesized that infants would use the same types of behaviors whether they have declarative or imperative communication goals. The Early Social Communication Scales (ESCS, Mundy et al., 2003) was administered to 103 typically developing infants of 12 months (approximately half of them siblings of children with autism). A factor analysis, yielding four behavioral factors, namely pointing, eye contact, actions and following points, confirmed the hypothesis that infants use behaviors consistently across situations independent of their communicative intent. MANOVAs (comprising parental education and income) revealed that higher SES infants showed actions more frequently in the ESCS whereas lower SES infants followed experimenter's points more frequently. The results are discussed in the context of presumably differing socialization goals for infants and the divergent contribution of parental education and income that seem to have additive contribution to some factors (actions, following points) but divergent contributions to others (pointing, eye contact).
