The role of elaboration in the persistence of awareness for degraded objects

When a fragmented line-drawing of an object moves relative to a background of randomly oriented lines, the previously hidden object can be segregated from the background and consequently enters awareness. In this shape-from-motion paradigm, the percept of the object briefly persists after the motion stops, demonstrating the maintenance of a bound percept in awareness. This study investigated how the manipulation of object features that are crucial to recognition influences both the binding process and the maintenance of objects in awareness. Overall, we found that objects that took longer to recognize (i.e., objects missing their vertices) were nonetheless maintained in awareness for longer. We argue that this effect is mediated by additional elaborative processing that is required to bind these less recognizable forms, which generates stronger and more robust representations. These representations are then more easily maintained in awareness, suggesting an important role of elaborative mechanisms for conscious representations.     

Sleep in children improves memory performance on declarative but not procedural tasks

Sleep supports the consolidation of memory in adults. Childhood is a period hallmarked by huge demands of brain plasticity as well as great amounts of efficient sleep. Whether sleep supports memory consolidation in children as in adults is unclear. We compared effects of nocturnal sleep (versus daytime wakefulness) on consolidation of declarative (word-pair associates, two-dimensional [2D] object location), and procedural memories (finger sequence tapping) in 15 children (6-8 yr) and 15 adults. Beneficial effects of sleep on retention of declarative memories were comparable in children and adults. However, opposite to adults, children showed smaller improvement in finger-tapping skill across retention sleep than wakefulness, indicating that sleep-dependent procedural memory consolidation depends on developmental stage.     

Toward a developmental psychology of Sehnsucht (life longings): the optimal (utopian) life

The topic of an optimal or utopian life has received much attention across the humanities and the arts but not in psychology. The German concept of Sehnsucht captures individual and collective thoughts and feelings about one's optimal or utopian life. Sehnsucht (life longings; LLs) is defined as an intense desire for alternative states and realizations of life. Presenting a first effort at capturing this phenomenon, the authors conceptualize LLs as composed of 6 interrelated core characteristics: (a) utopian conceptions of ideal development; (b) sense of incompleteness and imperfection of life; (c) conjoint time focus on the past, present, and future; (d) ambivalent (bittersweet) emotions; (e) reflection and evaluation of one's life; and (f) symbolic richness. Self-report data from 299 adults (19-81 years) support the postulated structure and support predictions regarding the functional role of Sehnsucht. Having LLs was evaluated as providing direction to development and helping to manage life's incompleteness. At the same time, the frequent and intense experience of LLs was associated with lower well-being. When LLs were perceived as controllable, however, this negative association disappeared.     

Multidisciplinary Engagement with Nanoethics Through Education—The Nanobio-RAISE Advanced Courses as a Case Study and Model

This paper presents and evaluates two advanced courses organised in Oxford as part of the European project Nanobio-RAISE and suggests using their format to encourage multidisciplinary engagement between nanoscientists and nanoethicists. Several nanoethicists have recently identified the need for ‘better’ ethics of emerging technologies, arguing that ethical reflection should become part and parcel of the research and development (R&D) process itself. Such new forms of ethical deliberation, it is argued, transcend traditional disciplinary boundaries and require the active engagement and involvement of both nanoethicists and nanoscientists with the broader issues surrounding technological developments. Whereas significant research efforts into multi- and interdisciplinary collaborations during R&D processes are now emerging, opportunities for encouraging multidisciplinary engagement through education have remained relatively underexplored. This paper argues that educational programmes could be a natural extension of ongoing collaborative research efforts ‘in the lab’ and analyses how the Nanobio-RAISE courses could be used as a model for course development. In addition to exploring how the elements that were conducive to multidisciplinary engagement in this course could be preserved in future courses, this paper suggests shifting the emphasis from public communication towards ethical deliberation. Further course work could thus build capacity among both nanoscientists and nanoethicists for doing ‘better’ nanoethics.     

Priming the ant or the grasshopper in people's mind: How regulatory mode affects inter‐temporal choices

The present study examined the influence of two regulatory mode concerns—a locomotion concern with movement from state to state and an assessment concern with making comparisons—on choices between immediate and delayed (from 2 to 6 weeks) money rewards. Regulatory mode orientation was induced by means of a priming procedure. We predicted that the choices in the assessment condition would be less impulsive and more far‐sighted than those in the locomotion condition. After taking into account the effects of amount of early reward, length of delay and increase in delayed reward—all of which were in the direction of previous studies—this regulatory mode prediction was supported. Our findings suggest that it might be possible to induce more far‐sighted (or economically rational) inter‐temporal choices by means of instructions that induce an assessment orientation independent of stable inter‐individual differences in discount rate.

The morphosyntactic decomposition and semantic composition of German compound words investigated by ERPs

In two experiments, we investigated the morphosyntactic decomposition and semantic composition of acoustically presented German compound words. A left-anterior negativity (LAN) was found in the ERP for gender incongruent, initial compound constituents although these constituents are syntactically irrelevant in German. This LAN provides online evidence for morphosyntactic decomposition. Experiment 1 showed also preliminary evidence for semantic composition, which was further investigated in Experiment 2 by comparing semantically transparent and opaque compounds. Transparent compounds elicited an increased negativity with a centroparietal maximum that occurred during the presentation of the head constituent. This negativity is suggested to reflect the semantic integration of compound constituents that is necessary after the constituents have been accessed separately.     

The Developmental Perspective in Integral Counseling

The process of making meaning is a core determinant of human experience. Understanding this process, developmentally, is a vital part of integral counseling. In this article, the authors introduce the concept of ego development stages as increasingly complex and flexible systems of meaning making. An understanding of ego development stages can help counselors to assist clients in a way that recognizes that people not only come in different “types” but also differ significantly in the level of their meaning‐making capacity.     

Problem Solvers Adjust Cognitive Offloading Based on Performance Goals

When incorporating the environment into mental processing (cf., cognitive offloading), one creates novel cognitive strategies that have the potential to improve task performance. Improved performance can, for example, mean faster problem solving, more accurate solutions, or even higher grades at university.¹ Although cognitive offloading has frequently been associated with improved performance, it is yet unclear how flexible problem solvers are at matching their offloading habits with their current performance goals (can people improve goal‐related instead of generic performance, e.g., when being in a hurry and aiming for a “quick and dirty” solution?). Here, we asked participants to solve a cognitive task, provided them with different goals—maximizing speed (SPD) or accuracy (ACC), respectively—and measured how frequently (Experiment 1) and how proficiently (Experiment 2) they made use of a novel external resource to support their cognitive processing. Experiment 1 showed that offloading behavior varied with goals: Participants offloaded less in the SPD than in the ACC condition. Experiment 2 showed that this differential offloading behavior was associated with high goal‐related performance: fast answers in the SPD, accurate answers in the ACC condition. Simultaneously, goal‐unrelated performance was sacrificed: inaccurate answers in the SPD, slow answers in the ACC condition. The findings support the notion of humans as canny offloaders who are able to successfully incorporate their environment in pursuit of their current cognitive goals. Future efforts should be focused on the finding's generalizability, for example, to settings without feedback or with high mental workload.     

The Effects of Nonverbal Immediacy and Verbal Person Centeredness in the Emotional Support Process

This study explores the combined influence of nonverbal immediacy and verbal person centeredness in the emotional support process. Three complementary models were tested in an experiment with 216 participants who disclosed an emotionally upsetting event to a confederate trained to display different levels of nonverbal immediacy and person centeredness. Participants subsequently completed a set of instruments measuring the perceived comforting quality of the confederate. Results suggested that nonverbal immediacy and person centeredness influence perceptions of what makes for good comforting. The data supported 2 of the advanced models but failed to provide support for a nonverbal primacy effect on perceived comforting quality.     

Perceived Risk of AIDS: Assessing the Behavioral and Psychosocial Consequences in a Cohort of Gay Men1

Longitudinal analyses reported here explored the relationship between a perceived sense of being at risk for AIDS and a variety of behavioral, social, and psychological consequences. Data were obtained from a cohort of 637 homosexual men living in Chicago, who are participating in a psychosocial study and have completed two waves of data collection. Their perceptions of risk were quantified using both an absolute and a comparative measure; these were combined into a risk index, scored from one to nine (x?= 3.91; SD= 1.64). Univariate analyses demonstrated that level of risk was related to several measures of subsequent behavioral risk reduction. However, after adjustment for sociodemographic variables, initial behavior, and other components of a model predicting behavior change, this was no longer true. Of the 12 behavioral outcomes assessed, only one was related to risk after appropriate adjustment, and this relationship was negative. Other longitudinal analyses examined the impact of a sense of risk on measures of psychosocial functioning which have been theoretically linked to health behaviors and to measures of psychological/ social distress. These demonstrated a range of potentially adverse consequences for those who perceived themselves to be at greater risk for AIDS, including increased barriers to behavioral change, obsessive/compulsive behavior, social role impairment, and more intrusive worries and concerns about AIDS. Taken together, these results suggest that there is little or no observable benefit to an increased sense of risk, but that such a sense subsequently leads to distress and dysfunction in a variety of realms. The implications of these findings for development of policy concerning antibody testing of at-risk populations is discussed.
