Language acquisition following hemidecortication: Linguistic superiority of the left over the right hemisphere

The language development of three 9- and 10-year-old children possessing only a right or a left hemisphere was studied. Surgical removal of one brain half antedated the beginning of speech, so each child has acquired speech and language with only one hemisphere. Different configurations of language skill have developed in the two isolated hemispheres: phonemic and semantic abilities are similarly developed but syntactic competence has been asymmetrically acquired. In relation to the left, the right brain half is deficient in understanding auditory language, especially when meaning is conveyed by syntactic diversity; detecting and correcting errors of surface syntactic structure; repeating stylistically permuted sentences; producing tag questions which match the grammatical features of a heard statement; determining sentence implication; integrating semantic and syntactic information to replace missing pronouns; and performing judgments of word interrelationships in sentences. Language development in an isolated right hemisphere, even under seizure-free conditions, results in incomplete language acquisition.     

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.     

Contralateral interference and ear advantages for identification of three-element patterns

Recent experience with attempts to test relatively simple patterns such as three-tone sequences in a traditional dichotic-listening paradigm indicates that when such sequences are used for both target and contralateral interference, performance tends to be low in both ears and not useful for measuring or comparing ear advantages in various target conditions. It is reported that tests with a variety of sounds presented contralaterally to three-element patterns show that several such sounds can (1) allow performance in at least one ear to remain above floor values, (2) result in performance in at least one ear that is below ceiling, and (3) reveal ear advantages that are similar in direction and magnitude to those seen with the traditional dichotic paradigm.     

A New Culture of Learning: Digital Storytelling and Faith Formation

How has the “new culture of learning” begun to transform us, and in what ways might the faith formation practices of religious communities be impacted by the shift? Recent research funded by the MacArthur Foundation lays an empirical basis for recognizing shifts in learning brought about by widespread access to digital technologies. The implications of that research, in turn, pose widespread challenges to the work of faith formation in contemporary communities of faith. Communicative theologies may be best poised to engage these challenges through the practices of digital storytelling.     

Kotahitanga and koinonia in shalom as the objective of the mission of God

Evangelical theology and the missions that flowed from it was born in an era of high colonialism, shaped by enlightenment dualism and scientific method, under the influence of industrialization. As evangelical Christianity’s centre of gravity shifted south, global North dominance over its theology and missiology persisted, translated into new tongues. This paper, sensing a tipping point in evangelical thought as we emerge out of global pandemic disruption, proposes an alternative framing of church and missions from the collectivist perspective shared by those less affected by the influence of Western industrialization and individualism. It proposes that both the means and the objective of the mission of God should be common unity in-Christ. It shifts focus from the Great Commission to the Great Commitment, which emphasizes being one and holding fast to that unity for the joy that awaits those who persevere in mutuality. Along the way, the demonstration of whole-of-life covenantal community in-Christ serves as our witness to the world, which provides those of us in-Christ with an opportunity to explain the hope that we have and invite others to join us in the experience of God’s shalom goodness.     

Reconciliation and the Great (whole) Commission

The label “Great Commission,” attributed to Matthew 28:16-20, has been for evangelicals the inspiration for the evangelization of the world for over a century. But there is more to the commissioning words of Jesus than the ministry of evangelism. This article contends that a missiology of reconciliation, applied to “the Great Commission,” uncovers the broader, holistic nature of the mission of the church. In addition to evangelism, reconciliation as mission also includes peacemaking and stewardship.     

The effects of exposure to political and domestic violence on preschool children and their mothers

The purpose of this study was to examine the effects of exposure to political violence on preschool children and their mothers. We explored whether these dyads are different from dyads with no known history of exposure to violence and from mother–child dyads with known exposure to domestic violence. Specifically, we explored differences in mothers' psychological status (depression and anxiety), dyadic emotional availability (EA), children's social information processing, and children's social behaviour, in a sample of 216 dyads divided into three groups (exposure to political violence, no exposure to violence, and exposure to domestic violence). We found evidence to support our hypotheses that children exposed to domestic violence exhibit the highest levels of social maladjustment with smaller but still significant differences between children exposed to political violence and children in the comparison group. As expected, the lowest EA scores were found in the exposure to domestic violence group, followed by dyads in the exposure to political violence group. Dyads belonging to the comparison group (no exposure) exhibited the highest levels of EA. These findings contribute to our understanding of the meaning of exposure to political violence, as well as sharpen the difference between exposure to political and domestic violence.
