Valuing Values: Better Public Engagement on Nanotechnology Demands a Better Understanding of the Diversity of Publics

As public attitude research evolves, often becoming more complex and variable, we are coming to understand that public attitudes are also more complex and variable than can often be captured by a single opinion poll, and more sophisticated forms of analyses are needed that look not just at a breadth of attitudes, but at a breadth of publics. The Australian Department of Industry undertook a public attitude study in 2012 that was not only longitudinal, looking at changes in attitudes towards nanotechnologies, but also looking at the values or worldviews that influence attitudes. The findings allowed for a segmentation of the public, into four key segments, with distinct homogenous attitudes. This allows for not just a deeper understanding of the diversity of views that exist and the worldviews that influence them, but challenges engagement practitioners to ensure they have a broad representation of participants with different attitudes and do not favour one or two segments only.     

Wellness as Fairness

I argue that distinct conditions of justice lead to diverse wellness outcomes through a series of psychosocial processes. Optimal conditions of justice, suboptimal conditions of justice, vulnerable conditions of injustice, and persisting conditions of injustice lead to thriving, coping, confronting, and suffering, respectively. The processes that mediate between optimal conditions of justice and thriving include the promotion of responsive conditions, the prevention of threats, individual pursuit, and avoidance of comparisons. The mechanisms that mediate between suboptimal conditions of justice and coping include resilience, adaptation, compensation, and downward comparisons. Critical experiences, critical consciousness, critical action, and righteous comparisons mediate between vulnerable conditions of injustice and confrontation with the system. Oppression, internalization, helplessness, and upward comparisons mediate between persisting conditions of injustice and suffering. These psychosocial processes operate within and across personal, interpersonal, organizational and community contexts. Different types of justice are hypothesized to influence well-being within each context. Intrapersonal injustice operates at the personal level, whereas distributive, procedural, relational, and developmental justice impact interpersonal well-being. At the organizational level, distributive, procedural, relational and informational justice influence well-being. Finally, at the community level, distributive, procedural, retributive, and cultural justice support community wellness. Data from a variety of sources support the suggested connections between justice and well-being.     

General mental ability in the world of work: occupational attainment and job performance

The psychological construct of general mental ability (GMA), introduced by C. Spearman (1904) nearly 100 years ago, has enjoyed a resurgence of interest and attention in recent decades. This article presents the research evidence that GMA predicts both occupational level attained and performance within one's chosen occupation and does so better than any other ability, trait, or disposition and better than job experience. The sizes of these relationships with GMA are also larger than most found in psychological research. Evidence is presented that weighted combinations of specific aptitudes tailored to individual jobs do not predict job performance better than GMA alone, disconfirming specific aptitude theory. A theory of job performance is described that explicates the central role of GMA in the world of work. These findings support Spearman's proposition that GMA is of critical importance in human affairs.     

Colour vision brings clarity to shadows

We have revealed a new role for colour vision in visual scene analysis: colour vision facilitates shadow identification. Shadows are important features of the visual scene, providing information about the shape, depth, and movement of objects. To be useful for perception, however, shadows must be distinguished from other types of luminance variation, principally the variation in object reflectance. A potential cue for distinguishing shadows from reflectance variations is colour, since chromatic changes typically occur at object but not shadow boundaries. We tested whether colour cues were exploited by the visual system for shadow identification, by comparing the ability of human test subjects to identify simulated shadows on chromatically variegated versus achromatically variegated backgrounds with identical luminance compositions. Performance was superior with the chromatically variegated backgrounds. Furthermore, introducing random colour contrast across the shadow boundaries degraded their identification. These findings demonstrate that the visual system exploits inbuilt assumptions about the relationships between colour and luminance in the natural visual world.     

The long-term effects of coping strategy use in victims of bullying

The ways in which children appraise and cope with school bullying are likely to influence the long-term outcomes experienced. To examine this possibility, 219 Spanish undergraduate students (73 male, 146 female) aged between 18 and 40, completed an adapted version of the Retrospective Bullying Questionnaire (RBQ; Sch?fer et al., 2004) and a distress scale (Rivers, 1999). Results indicated that neither coping strategies reported by victims of bullying nor the match between control appraisal and coping strategy influenced levels of distress experienced as adults. Control, threat and challenge appraisals did, however, influence long-term distress. Explanations for these effects are discussed, and include the possibility that appraisals may directly influence levels of distress and the quality of emotions experienced by victims during the actual bullying episode. Active strategies were perceived by students to be effective in dealing with bullying, whereas those centered on avoiding the conflict, or which involved aggression, were considered ineffective.     

Gaze-contingent displays: a review.

Gaze-contingent displays (GCDs) attempt to balance the amount of information displayed against the visual information processing capacity of the observer through real-time eye movement sensing. Based on the assumed knowledge of the instantaneous location of the observer's focus of attention, GCD content can be "tuned" through several display processing means. Screen-based displays alter pixel level information generally matching the resolvability of the human retina in an effort to maximize bandwidth. Model-based displays alter geometric-level primitives along similar goals. Attentive user interfaces (AUIs) manage object- level entities (e.g., windows, applications) depending on the assumed attentive state of the observer. Such real-time display manipulation is generally achieved through non-contact, unobtrusive tracking of the observer's eye movements. This paper briefly reviews past and present display techniques as well as emerging graphics and eye tracking technology for GCD development.     

Discriminative taste aversion learning: a learning task for older chickens

The study of learning and memory using the chicken model has relied on three learning paradigms, passive avoidance learning, imprinting and the pebble floor task. Passive avoidance learning and imprinting have been used predominantly in very young chickens and cannot be used to access learning and memory in older chickens. We have established a new behavioural learning paradigm, Discriminative Taste Aversion Learning (DTAL), that can be used with both young and older animals. The task requires chickens to discriminate between food crumbs dyed either red or yellow with one colour being associated with the aversive tasting substance, methylanthranilate. Learning can be tested at various times after the training session by presenting chickens with the coloured food crumbs without an aversive taste. Both chickens tested at 5 and 15 days post-hatch learned to avoid the aversive crumbs. Furthermore, the protein synthesis inhibitor anisomycin (30 mM; 10 microl per hemisphere) injected into the intermediate medial hyperstriatum ventrale 15 min pre-training or 45 min post-training blocked long-term memory for the DTAL task when tested 24 h later. Memory for the task was unaffected by anisomycin injection 120 min post-training or in control animals injected with saline at similar times. The timing of the cellular processes of protein synthesis needed for consolidation of the DTAL appears to be similar to those described for the other behavioural paradigms in young chickens.     

Are there critical bands in kinesthesia?

The effect of changing the bandwidth of noise on the ability of human subjects to detect a 10-Hz sinusoidal movement signal was measured in two experiments. The objective of these studies was to investigate whether critical bands exist for the kinesthetic system, as has been demonstrated for the auditory and tactile systems. It was found that subjects' ability to detect a 10-Hz sinusoidal movement stimulus embedded in noise was not influenced by the bandwidth of the noise over a range of 4-10 Hz. These findings suggest that, if a critical filter does exist for this system, it would have to be greater than 10 Hz.
