Aided speech-identification performance in single-talker competition by older adults with impaired hearing

This study examined the effects of increased processing load on the closed-set speech-identification performance of young and older adults in a one-talker background. Since the older adults had impaired hearing, speech-identification performance was measured for spectrally shaped stimuli comparable to those experienced when wearing well-fit hearing aids. There were three groups of listeners: (1) 19 older adults with high-frequency sensorineural hearing loss; (2) 10 young adults with normal hearing who were assessed with the same spectrally shaped stimuli as the older adults; (3) 9 young adults with normal hearing who were assessed without spectral shaping and at a poorer target-to-competition ratio in an effort to equate overall performance to that of the older adults. In addition to this group factor, there were three within-participant repeated-measures independent variables designed to increase the demands on processing for the target and competing speech stimuli. These were: (1) competition meaningfulness (played in forward or reverse direction); (2) gender match between target and competing talkers (same or different gender); and (3) talker uncertainty (either the same target/competition talker pair or one of many such pairs on each trial). These three repeated-measures independent variables were examined in a 2 × 2 × 2 factorial design. They showed roughly independent and additive effects on speech-identification such that combinations of these variables decreased performance cumulatively. Older adults performed worse than young adults across the board, but also showed diminished relative improvement as the processing load was decreased. Individual differences in performance among the older adults were also examined.     

SOME ISSUES IN CONVERSATION COHERENCE

This study examined respondent proficiency at reconstructing a sequence of utterances (discourse). Theories of text hold that participants in a discourse must construct and arrange the sense of the text; that is, they must make decisions about discourse coherence. We had respondents reconstruct a conversation and we made predictions about discourse coherence, the nature of various two-turn constructional units, unit differences, and individual differences. We found that the entire discourse as a processing unit affects the likelihood of certain two-turn pairs being resequenced correctly. Except for the fact that complex subjects were better able to resequence the initial interaction, there were no other individual differences. The research has implications for principles of coherence, text comprehension, and interpersonal behavior.     

THE EFFECTS OF ORDER OF EXERCISE PRESENTATION ON ASSESSMENT CENTER PERFORMANCE: ONE STANDARDIZATION CONCERN1

Internal invalidity concerns in the administration of an Assessment Center were surfaced. Specifically, the effects of order of exercise presentation were studied. Contrary to expectations, the effects of varying exercise presentation orders on Assessment Center performance were not significant. Possible explanations for the absence of the hypothesized results were offered. Given the realistic impact of Type II errors in actual business environments, further study in naturally occurring field settings is encouraged to control for expected sources of invalidity.     

ON THE PRESCRIBING ANALYST

The value of medication for some patients in psychoanalysis serves to highlight the potential challenges of the medical analyst and invites exploration into possible motivations for assuming the prescribing role. Prescribing medication is one way in which the medical analyst integrates the dual identities of physician and analyst while dealing with significant cultural influences and intrapsychic tensions. Technical challenges posed by assuming the prescribing role are explored, as are the potential benefits of split treatment. The educational implications of this argument are discussed in relation to identity formation for candidates who are physicians.     

The Adventure of Research

In recent years, a number of studies corroborate the importance of an integrated or interdisciplinary curriculum for an effective education. However, contemporary proposals for the function of theology as the integrative center have been limited mainly to sectarian communities and remain a work in progress. Noting the fruitfulness of historical and worldview surveys of the relationship between theology and education in the works of Holmes, Knight, and Blamires, this essay is an attempt to contribute to these approaches by demonstrating how current research in biblical and patristic studies can contribute models for the integration of curricula and provide a more effective Christian education. Included are analyses of the counter-imperial thesis for Paul's theology and how it breaks down walls between Bible, Literature, History, and Government classes, the emergence of a distinctly Christian paideia and its contribution to the formation of Christian character, and the concept of cosmological axioms entailed in sacred discourse which provide a comprehensive interdisciplinary application of the lordship of Christ. Observations on the implications of such models for Christian education are then drawn from the data.
