Shifts of spatial attention cued by irrelevant numbers: Electrophysiological evidence from a target discrimination task

Fischer et al. demonstrated that a centrally presented number can shift attention to the left/right when its magnitude is small/large. Two electrophysiological studies described these attentional effects as event-related potentials (ERPs) at centro-parietal sites. Since both studies used target detection tasks, it remains currently unknown whether similar results would be obtained with a discrimination task. We used ERPs to test whether digit cues also induce attention shifts when participants perform a feature-discrimination task on targets. ERPs were recorded whereas subjects discriminated the colour of lateral targets that were preceded by a central non-predictive digit. Analysis of cue-locked controlateral vs. ipsilateral ERP activity showed the emergence of early preparatory attention-directing components in parietal and frontal regions. Moreover, target-locked P1 components at occipito-parietal sites were significantly modulated by digit magnitude-target side congruency. These results demonstrate that irrelevant digit cues also bias sensory processing when embedded in a feature-discrimination task.     

Life Balance and Well‐Being: Testing a Novel Conceptual and Measurement Approach

ABSTRACT Although a balanced life has always been viewed as desirable, there are problems with extant conceptualizations and measures of this construct. Here we introduce 2 new life‐balance measures, based on time‐use profiles, that address these problems. One defines life balance as objectively equitable time use across multiple life domains, and the other defines life balance as low subjective discrepancy between actual and ideal time‐use profiles. Study 1 finds that both measures predict concurrent well‐being, in both U.S. and Indian samples. Study 2 shows that fluctuations in balance predict fluctuations in well‐being over a 3‐week period. Study 3 replicates the Study 1 findings using a different time assessment technique, based on the Day Reconstruction Method. Study 4 assigns participants the month‐long goal of enhancing their life balance, finding that those who achieve this goal enhance their well‐being. In all 4 studies, the balance effects on well‐being were mediated by psychological need satisfaction associated with balance.     

Role of Researchers in the Ethical Conduct of Research: A Discourse Analysis From Different Stakeholder Perspectives

The ethical conduct of research rests largely on researchers, and as such, an understanding of how they perceive and enact their role in research is paramount. However, the literature around ethics and research mostly focuses on researchers’ perception of Research Ethics Boards (REB; also known as Institutional Review Boards) roles and functions. To fill that gap, we analyzed the perceptions of researchers, REB members, and influential parties (n = 40) about researchers’ role in the ethical conduct of research through discourse analysis. Three discourses emerged: researchers as reflective practitioners, protectors of participants, and technicians. Understanding the commonalities and differences among the discourses may foster a shared and compelling institutional research culture.     

A Note on Modulations and Structuring of Locomotion in Children and Adults

The aim of this study was to investigate the modulations of locomotion induced by a rhythmic cognitive task (counting one’s steps). Subjects (6-and 8-year-olds and adults) were requested to walk freely, and then to walk while counting their steps. Here a decrease in cadence values was observed in children only, with quasi-total repercussions on velocity at the age of 6 only. The spatiotemporal structuring of locomotion described here is already present at 6 years of age and is not altered in the step-counting situation: strong links were observed between cadence and velocity, and between stride length and velocity, and weak links between cadence and stride length.     

Of “sleep and dream: A psychoanalytic essay' by Joyce McDougall (discussion)

Abstract

The author describes experiences gathered during several years of teaching psychodynamic psychotherapy with psychologists and psychiatrists within a 2-year-training programme in Shanghai, China. Questions and problems of the reception of psychoanalysis – shame, sexuality, harmony, abstinence – as well as the possibilities and limitations of exporting psychoanalysis are discussed. The possible future development of psychoanalysis in China is also outlined.     

EDITORIAL

Applying the thoughts of Tustin, Ogden and Winnicott, this paper describes the sources and the dynamics of the autistic encapsulation, the earliest auto-sensory defence of the personality. Detailed clinical material illustrates the working-through process of the autistic defensive strategy in the analysis of an adult person.     

Excitation Transfer Effects Between Semantically Related and Temporally Adjacent Stimuli

Although excitation transfer theory has been supported in numerous contexts, questions remain regarding transfer of arousal between events that are semantically and temporally related. This article summarizes two studies exploring excitation transfer between such events: sequential plays from a college football game. Study 1 failed to support the theory, instead suggesting contrast effects between stimuli. A follow-up study, which altered the method and incorporated psychophysiological measures, demonstrated that arousal may transfer between semantically related, temporally adjacent events. We suggest implications for the theory vis-à-vis misattribution of arousal, as well as opportunities to expand the application of excitation transfer.     

Maintaining Life Satisfaction: The Role of Positive Cognitive Bias

Recent research into population standards of life satisfaction has revealed a remarkable level of uniformity, with the mean values for Western populations clustering at around three-quarters of the measurement scale maximum. While this seems to suggest the presence of a homeostatic mechanism for life satisfaction, the character of such a hypothetical device is uncertain. This paper proposes that well-being homeostasis is controlled by positive cognitive biases pertaining to the self. Most particular in this regard are the positive biases in relation to self-esteem, control and optimism. Past controversies in relation to this proposition are reviewed and resolved in favour of the proposed mechanism. The empirical data to support this hypothesis are discussed in the context of perceived well-being as an adaptive human attribute.
