Mental health professionals' attitudes towards people who are deaf

Mental health professionals' attitudes towards deaf people were examined in relation to their previous contact with deaf people and their knowledge of deafness. Data were gathered regarding different aspects of contact, including the number and type of relationships participants had had with deaf people. A cognitive-processing theory of attitude change following contact (Rothbart & John, 1985) was explored. Knowledge of deafness did not correlate with attitudes towards deaf people but a relationship was found between the amount of contact that professionals had with deaf people of equal or higher status and more positive attitudes.     

Calibrating the sociometer: the relational contingencies of self-esteem

A longitudinal daily diary study examined how chronic perceptions of a partner's regard for oneself might affect the day-to-day relational contingencies of self-esteem. Married partners each completed a diary for 21 days, and completed measures of satisfaction twice over the year. Multilevel analyses revealed that people who chronically felt more positively regarded compensated for one day's acute self-doubts by perceiving greater acceptance and love from their partner on subsequent days. In contrast, people who chronically felt less positively regarded by their partner internalized acute experiences of rejection, feeling worse about themselves on days after they feared their partner's disaffection. Over the year, such self-esteem sensitivity to rejection predicted declines in the partner's satisfaction.     

Auditory neuropathy/dys-synchrony: diagnosis and management

Auditory brainstem responses (ABRs) and otoacoustic emissions (OAEs) are objective measures of auditory function, but are not hearing tests. Normal OAEs reflect normal cochlear outer hair cell function, and an ABR indicates a synchronous neural response. It is quite possible for a patient to have normal OAEs but absent or grossly abnormal ABR and a behavioral audiogram that is inconsistent with either test. These patients, who may constitute as much as 10% of the diagnosed deaf population, have auditory neuropathy/dys-synchrony (AN/AD). To diagnose AN/AD accurately, ABRs are obtained in response to condensation and rarefaction clicks to distinguish cochlear microphonics (CM) from neural responses. Appropriate management is confounded by variation among patients and changes in auditory function in some patients over time. Recommendations for management include visual language exposure through methods such as American Sign Language (ASL), Cued Speech, or baby signs, and closely following patients.     

Speech timing and working memory in profoundly deaf children after cochlear implantation

Thirty-seven profoundly deaf children between 8- and 9-years-old with cochlear implants and a comparison group of normal-hearing children were studied to measure speaking rates, digit spans, and speech timing during digit span recall. The deaf children displayed longer sentence durations and pauses during recall and shorter digit spans compared to the normal-hearing children. Articulation rates, measured from sentence durations, were strongly correlated with immediate memory span in both normal-hearing and deaf children, indicating that both slower subvocal rehearsal and scanning processes may be factors that contribute to the deaf children's shorter digit spans. These findings demonstrate that subvocal verbal rehearsal speed and memory scanning processes are not only dependent on chronological age as suggested in earlier research by. Instead, in this clinical population the absence of early auditory experience and phonological processing activities before implantation appears to produce measurable effects on the working memory processes that rely on verbal rehearsal and serial scanning of phonological information in short-term memory.     

The historical roots of the theories of local signs and labelled lines

The theories of labelled lines and local signs are commonly invoked to explain numerous perceptual phenomena. These theories postulate that perceptual systems use information about which nerve cells or which information channels are activated by the stimulus. The origins of this idea in nineteenth century German psychophysics are traced. From Descartes's idea of a dualistic mind, Kant's idea of a mental ability to conceive space, Da Vinci's ideas of pictorial 'signs', and Müller's idea of 'specific nerve energies' to explain perceptual qualities, Steinbuch, Lotze, and others derived the conclusion that neural-level signs exist that signal stimulus location to the mind. Helmholtz, Hering, and others soon suggested variations on this basic idea. By the time of James the theory had changed yet again. It was revived elsewhere in the 1920s and again in the 1970s, although used implicitly by many workers in between and since. Against a modern metaphysical background, however, a distinction between labels (hardware) and signs (symbols) is the minimum step needed towards an appropriate and comprehensive explanation of perceptual behaviour and experience.     

Practical Considerations and Alternative Research Methods for Evaluating HR Programs

Program evaluation methods capitalizing on quasi-experimental designs are introduced as useful alternatives for evaluating human resources (HR) programs such as selection systems, training courses, performance measurement systems, and 360 degree feedback. A case study is presented to illustrate the benefits of program evaluation methods for evaluating HR programs. In addition, several post-hoc considerations that often moderate results from HR evaluations are described. It is suggested that when these considerations are addressed, quasi-experimental program evaluation methods provide a promising tool for demonstrating bottom line impact of HR initiatives.     

Expression of Fos and Jun Proteins Following Passive Avoidance Training in the Day-Old Chick

It has been shown previously that the immediate-early genes, c-fos and c-jun mRNA are induced in the 1-day-old chick forebrain after one-trial passive avoidance training in which chicks learn to avoid pecking at a bitter-tasting bead. Here, we have studied the expression of their proteins using antibodies to Fos and Jun. Western blotting disclosed two immunoreactive bands for the anti-Fos antibody (47 and 54 kD) and two immunoreactive bands for the anti-Jun antibody (39 and 54 kD). Two hours post-training there was an increase in the number of Fos-positive stained nuclei in right intermediate medial hyperstriatum ventrale (IMHV) (P<0.01), left IMHV (P<0.05), right lobus parolfactorius (LPO) (P<0.025) and left LPO (P<0.05) of birds trained on the bitter bead compared with controls that had pecked a water-coated bead. Staining for Jun protein was significantly greater in the right LPO of trained chicks (P<0.01). Other forebrain regions showed no increase over quiet control levels. The findings are discussed in the context of the cascade of events involved in passive avoidance memory consolidation in the day-old chick.     

Do authorship policies impact students' judgments of perceived wrongdoing?

Although authorship policies exist, researchers understand little about their impact on perceptions of authorship scenarios. Graduate students (N=277) at a large university read 1 of 3 vignettes about a graduate student-faculty collaboration. One half of the surveys included the American Psychological Association's statement on authorship. Participants rated (a) the ethics of the professor as first author and (b) the likelihood of a dissatisfied student reporting the authorship result, as well as the effectiveness and negative consequences of reporting. Work arrangements on the project had a consistent main effect. Also, an authorship policy impacted women's ratings of first authorship when the student contributed the idea for a project. For men, a policy impacted only ratings of the likelihood of reporting when a professor was first author on a student's dissertation. Apart from sex, no other demographic variables on participants were predictive. Discussion focuses on the policy's potential for making only some specific issues salient.
