An ethical problem concerning recent therapeutic research on breast cancer

The surgical treatment of breast cancer has changed in recent years. Analysis of the research that led to these changes yields apparently good arguments for all of the following: (1) The research yielded very great benefits for women. (2) There was no other way of obtaining these benefits. (3) This research violated the fundamental rights of the women who were research subjects. This sets a problem for ethics at many levels.     

Understanding the Mental Health Travails of Custodial Grandparents

Grandcarers are at-risk of poor mental health outcomes. Current knowledge of the support needs of grandcarers is fragmented. To help fill this knowledge gap qualitative analysis was undertaken on 49 interviews conducted with custodial grandparents. The findings reveal that conflicted occupational roles coupled with the complexity of the stressors facing grandcarers both contribute to their social isolation and to their self-doubts about their ability to adequately attend to their grandchildren’s needs. Greater awareness among occupational therapists (OTs) of custodial grandparents’ mental health travails and an increased understanding of key occupational therapy (OT) practice initiatives are central to addressing grandcarers’ mental health travails.     

Initial morphological learning in preverbal infants

How do children learn the internal structure of inflected words? We hypothesized that bound functional morphemes begin to be encoded at the preverbal stage, driven by their frequent occurrence with highly variable roots, and that infants in turn use these morphemes to interpret other words with the same inflections. Using a preferential looking procedure, we showed that French-learning 11-month-olds encoded the frequent French functor /e/, and perceived bare roots and their inflected variants as related forms. In another experiment an added training phase presented an artificial suffix co-occurring with many pseudo-roots. Infants learned the new suffix and used it to interpret novel affixed words that never occurred during the training. These findings demonstrate that initial learning of sub-lexical functors and morphological alternations is frequency-based, without relying on word meaning.     

Mindfulness‐Based Interventions in Counseling

Mindfulness is a relatively new construct in counseling that is rapidly gaining interest as it is applied to people struggling with a myriad of problems. Research has consistently demonstrated that counseling interventions using mindfulness improve well‐being and reduce psychopathology. This article provides a detailed definition of mindfulness, including a discussion of the mechanisms underlying mindfulness practice; explores the implementation of mindfulness as a counseling intervention; and examines literature supporting its effectiveness.     

Best Practices: A Critical Yet Inclusive Vision for the Counseling Profession

Substantial controversy has surrounded the concept of best practices (BPs) in counseling; in particular, the consequences of deriving practice guidelines from empirically supported treatments (ESTs). Criticisms of EST methodology, assumptions, and findings are summarized, and implications for core counseling values, including multiculturalism, are discussed. The authors further elaborate an inclusive view of BP that can facilitate the use of research to inform and enhance counseling services while rectifying problems associated with methodological and theoretical bias.     

Schema-based processing in auditory scene analysis

What is the involvement of what we know in what we perceive? In this article, the contribution of melodic schema-based processes to the perceptual organization of tone sequences is examined. Two unfamiliar six-tone melodies, one of which was interleaved with distractor tones, were presented successively to listeners who were required to decide whether the melodies were identical or different. In one condition, the comparison melody was presented after the mixed sequence: a target melody interleaved with distractor tones. In another condition, it was presented beforehand, so that the listeners had precise knowledge about the melody to be extracted from the mixture. In the latter condition, recognition performance was better and a bias toward same responses was reduced, as compared with the former condition. A third condition, in which the comparison melody presented beforehand was transposed up in frequency, revealed that whereas the performance improvement was explained in part by absolute pitch or frequency priming, relative pitch representation (interval and/or contour structure) may also have played a role. Differences in performance as a function of mean frequency separation between target and distractor sequences, when listeners did or did not have prior knowledge about the target melody, argue for a functional distinction between primitive and schema-based processes in auditory scene analysis.     

Removing Inconsistencies in Assumption-based Theories Through Knowledge-Gathering Actions

In this paper, the problem of purifying an assumption-based theory KB, i.e., identifying the right extension of KB using knowledge-gathering actions (tests), is addressed. Assumptions are just normal defaults without prerequisite. Each assumption represents all the information conveyed by an agent, and every agent is associated with a (possibly empty) set of tests. Through the execution of tests, the epistemic status of assumptions can change from "plausible" to "certainly true", "certainly false" or "irrelevant", and the KB must be revised so as to incorporate such a change. Because removing all the extensions of an assumption-based theory except one enables both identifying a larger set of plausible pieces of information and renders inference computationally easier, we are specifically interested in finding out sets of tests allowing to purify a KB (whatever their outcomes). We address this problem especially from the point of view of computational complexity.
