Auditory warnings, signal-referent relations, and natural indicators: re-thinking theory and application

In auditory warning design the idea of the strength of the association between sound and referent has been pivotal. Research has proceeded via constructing classification systems of signal-referent associations and then testing predictions about ease of learning of different levels of signal-referent relation strength across and within different types of auditory signal (viz., speech, abstract sounds, and auditory icons). However, progress is hampered by terminological confusions and by neglect of the cognitive contribution (viz., learning) of the person or user. Drawing upon semiotics and cognitive psychology, the authors highlight the indexical (as opposed to iconic) nature of so-called auditory icons, and the authors identify the cogniser as an indispensable element in the tripartite nature of signification. Classifications that neglect this third element, defining signal-referent relation strength only dyadically, yield results confounded by learning; classifications that correctly include the triadic relation yield research predictions that are redundant. These limitations of the standard method of constructing and testing classification systems suggest that auditory warning design must take the cognitive contribution of the user into account at an earlier stage in the design process.     

Perseverative and compulsive-like staring causes uncertainty about perception

Earlier studies have found that perseverative checking provokes memory distrust for checked stimuli, suggesting that compulsive checking is a counter-productive strategy to increase memory confidence. Obsessive Compulsive (OC) uncertainty also occurs for functions other than memory, like perception. Uncertainty about perception in OC patients gives rise to prolonged attending to the issues that patients feel uncertain about. In an experiment with 40 healthy volunteers, it was tested whether OC-like, perseverative (visual) attending induces OC-like experiences of dissociation and perceptual uncertainty. Participants had to look at an object (a gas stove or a light bulb) during a pre-test and a post-test. In between these tests, participants in the experimental condition were asked to stare at an object that was the same as the to-be-looked-at object during the pre/post-tests. Participants in the control condition stared at an object that was different from the object they looked at during pre/post-test. Both in the experimental and control conditions, dissociation was observed; the effects were equally strong. Critically, with regards to OC-like perceptual uncertainty, the effects were significantly stronger in the experimental condition. The findings indicate that OC-like perseveration induces distrust, not only about memory, but also about perception. To explain the results, we suggest that perseveration interferes with spreading of activation and that cognitive uncertainty (and possibly derealisation) is the experiential end-product of perseveration. It is suggested that all forms of OC perseveration share such interference and that all undermine confidence in cognitive operations.     

A Relational Approach to Genetic Counseling for Hereditary Breast and Ovarian Cancer

Ethical issues arise for genetic counselors when a client fails to disclose a genetic diagnosis of hereditary disease to family: they must consider the rights of the individual client to privacy and confidentiality as well as the rights of the family to know their genetic risk. Although considerable work has addressed issues of non-disclosure from the client’s perspective, there is a lack of qualitative research into how genetic counselors address this issue in practice. In this study, a qualitative approach was taken to investigate whether genetic counselors in Australia use a relational approach to encourage the disclosure of genetic information from hereditary breast and ovarian cancer (HBOC) clients among family members; and if so, how they use it. Semi-structured qualitative interviews were conducted with 16 genetic counselors from selected states across Australia. Data collection and analysis were guided by a basic iterative approach incorporating a hybrid methodology to thematic analysis. The findings provide indicative evidence of genetic counselors employing a relational approach in three escalating stages––covert, overt and authoritative––to encourage the disclosure of genetic information. The findings lend credence to the notion that genetic counselors envision a form of relational autonomy for their clients in the context of sharing genetic information, and they depart from individualistic conceptions of care/solely client-centered counseling when addressing the needs of other family members to know their genetic status.     

When deaf signers read English: do written words activate their sign translations?

Deaf bilinguals for whom American Sign Language (ASL) is the first language and English is the second language judged the semantic relatedness of word pairs in English. Critically, a subset of both the semantically related and unrelated word pairs were selected such that the translations of the two English words also had related forms in ASL. Word pairs that were semantically related were judged more quickly when the form of the ASL translation was also similar whereas word pairs that were semantically unrelated were judged more slowly when the form of the ASL translation was similar. A control group of hearing bilinguals without any knowledge of ASL produced an entirely different pattern of results. Taken together, these results constitute the first demonstration that deaf readers activate the ASL translations of written words under conditions in which the translation is neither present perceptually nor required to perform the task.     

Externalizing behavior trajectories: The role of parenting, sibling relationships and child personality

Based on longitudinal multilevel modeling and using a multi-informant strategy, this study examines trajectories of externalizing problem behavior (EPB) in childhood as predicted by parental behavior (absolute level of parenting [ALP] and parental differential treatment [PDT]), parental self-efficacy (PSE), child personality and sibling relationships. Besides main effects, several interactions were tested. The effects of changes in parenting on changes in EPB were also examined. A total of 119 families from the French-speaking area of Belgium rearing a child (3- to 5-year-olds at the onset of the study) referred for EPB were studied. The effects of both level-of and changes-in mothers' ALP were partially confirmed, but for fathers, only ALP was predictive. There were some significant interactions between ALP and PDT for both parents. Mothers' PSE explained some variance in EPB, additional to that explained by the parenting measures. Some parenting by personality and by sibling relationship interactions were found.     

Applying a Behavioral Epidemiology Framework to Research Phases in Child Health Psychology

The purpose of this study was to apply a behavioral epidemiology framework reported in J. F. Sallis, N. Owen, and M. J. Fotheringham (2000) to the field of child health psychology and describe the resulting distribution of research phases. Recent volumes of the Journal of Pediatric Psychology were analyzed and their articles classified as belonging to one of five sequentially-ordered phases of behavioral epidemiology research: Phase 1—relationship between behavior and health; Phase 2—measurement and method; Phase 3—factors influencing behavior; Phase 4—intervention; Phase 5—translation. The results indicate that Phase 3 studies (46%) were the most well-represented in the field, followed by Phase 2 (11%), Phase 1 (9%), Phase 4 (8%), and Phase 5 studies (2%). Compared to the journal Health Psychology, the shape of the research phase distribution of articles published in the Journal of Pediatric Psychology was similar. Overall, an encouraging amount of data in the field of child health psychology is being amassed in preparation for behavioral intervention. As research in the field matures, it will likely have a greater impact on public health via chronic disease prevention and control and health promotion interventions.
