Differentiation of retinal and nonretinal contributions to averaged evoked responses obtained with electrodes placed near the eyes

Recent visual evoked potential (VEP) studies suggest that during sustained voluntary attention, irrelevant or unattended visual stimuli may be filtered precortically. Testing of this hypothesis in humans requires knowledge of the origin of specific components of the VEP that are affected by selective attention. This study describes techniques and procedures for distinguishing between retinal and nonretinal components of VEPs recorded from electrodes placed strategically around the eyes and on the forehead. By visually stimulating one eye at a time while recording simultaneously from both, and by stimulating a given retinal area with the eyes fixated on the target at different angular deviations from the normal line of regard, components of the VEPs around the eyes can be distinguished as of retinal or nonretinal origin. The results are discussed in terms of volume conduction theory.     

Community health nurses' knowledge of, attitudes toward, and involvement with adolescent contraceptive services

A national sample of community health nurses were surveyed to assess their knowledge of, attitudes toward, and involvement with reproductive health services. Results indicated that slightly more than half of the nurses provided or administered contraceptive services to adolescents, although 73% worked in settings where contraceptive services were provided to adolescents. However, only 3.6% indicated that adolescents were their primary client population. The majority (64.3%) stated that they felt as prepared to work with adolescents as they did with adult clients. While 98% were aware that most adolescents are sexually active before seeking family planning services, a minority correctly answered questions about pregnancy and contraception among adolescents. Ninety-five percent agreed that contraceptives should be available to adolescents, and 90% agreed that parental consent should not be required for adolescents seeking contraceptive services. Yet only 21.5% were aware of the implications of the Adolescent Family Life Act.     

Information privacy in organizations: empowering creative and extrarole performance

This article examines the relationship of employee perceptions of information privacy in their work organizations and important psychological and behavioral outcomes. A model is presented in which information privacy predicts psychological empowerment, which in turn predicts discretionary behaviors on the job, including creative performance and organizational citizenship behavior (OCB). Results from 2 studies (Study 1: single organization, N=310; Study 2: multiple organizations, N=303) confirm that information privacy entails judgments of information gathering control, information handling control, and legitimacy. Moreover, a model linking information privacy to empowerment and empowerment to creative performance and OCBs was supported. Findings are discussed in light of organizational attempts to control employees through the gathering and handling of their personal information.     

Stress management training for law students: Cognitive-behavioral intervention

The practice of law has created chronic and, at times, severe psychological stress both in law school and subsequent practice. In the current study, students volunteered to participate in a six-session seminar on personal stress management skills including self-relaxation training, schedule planning, priority-setting, leisure time planning, and cognitive modification techniques. Subjects showed pre- to posttreatment improvement on a variety of measures that included their knowledge about stress, personal ratings of stressful situations, and their daily activity schedules. In contrast, a control group showed no improvement and worsened in reported levels of personal stress. The importance of providing law students with personal stress management skills is discussed.     

Ontogeny of spontaneous locomotor activity in rabbit, rat, and guinea pig.

Postnatal locomotor activity was investigated in rabbit, rat, and guinea pig. A peak was found in this behavior at 5 days of age in the rabbit and, in confirmation of earlier studies, at 15-20 days in the rat. Neonatal guinea pigs showed no variation in activity levels due to age. The guinea pig is born at an advanced stage of neural maturation in comparison with the rat, and the rabbit is born at an intermediate stage. This difference accounts for the observed variations in postnatal activity profiles if it is assumed that the behavioral peak coincides with the transition from a stage of primarily mesencephalic arousal system maturation to a stage of primarily diencephalic and telencephalic inhibitory system maturation.     

VARIETIES OF VIRTUE ETHICS

The revival of virtue ethics over the last thirty-five years has produced a bewildering diversity of theories, which on the face of it seem united only by their opposition to various features of more familiar Kantian and Utilitarian ethical theories. In this paper I present a systematic account of the main positive features of virtue ethics, by articulating the common ground shared by its different varieties. I do so not to offer a fresh defence of virtue ethics, but rather to provide a conceptual map that locates its main claims and arguments in relation to those of rival theories, and identifies its distinctive contribution to contemporary ethics. I set out six specific claims which are made by all forms of virtue ethics, and I explain how these claims distinguish the theory from recent character-based forms of Kantian ethics and Utilitarianism. I then use this framework to briefly survey two main strands of virtue ethics which have been developed in the literature.¹

Dark clouds

This essay is in part a response to a cluster of papers from the conference in Norway. Utilising these as a springboard to expand certain ideas, some latent, some more manifest in the papers, regarding the history and the terrain concerning the mental health issues in our culture. Fundamentally, this proposes that there is an unrelenting tension between two polarities: one reactionary and authoritarian, fixated on a concern with outcomes, propped up by closed systems of thought, managerial, habitually linked to adaptation and conformity; the other more romantically seen as revolutionary, unhandcuffing madness from mental illness, facilitating more expansive, freewheeling possibilities within all our lives. Much of this pays tribute to some of the major figures in the history of ‘anti-psychiatry’ (Basaglia, Cooper and Laing), with the costs involved, and goes on to trace out the genesis and consequences of the two predominant ‘clouds’ permeating our world, the paranoid and the digital … all converging on a naturalisation of our culture of surveillance, and an insistence on control. Otherwise known as a culture of fear.     

Does 'hypnosis' by any other name smell as sweet? The efficacy of 'hypnotic' inductions depends on the label 'hypnosis'

Hypnosis is associated with profound changes in conscious experience and is increasingly used as a cognitive tool to explore neuropsychological processes. Studies of this sort typically employ suggestions following a hypnotic induction to produce changes in perceptual experience and motor control. It is not clear, however, to what extent the induction procedure serves to facilitate suggested phenomena. This study investigated the effect on suggestibility of (a) a hypnotic induction and (b) labelling that procedure 'hypnosis.' Suggestibility of participants was tested before and after an adapted hypnotic procedure, which was either labelled as 'hypnosis' or as 'relaxation.' The hypnotic procedure produced a modest increase in suggestibility when it was called 'relaxation,' but a very significant increase if it was labelled 'hypnosis.' The results are important for both clinical and experimental applications and indicate that labelling an induction procedure 'hypnosis' is an important determinant of subsequent responses to suggestion.
