What Values in Design? The Challenge of Incorporating Moral Values into Design

Recently, there is increased attention to the integration of moral values into the conception, design, and development of emerging IT. The most reviewed approach for this purpose in ethics and technology so far is Value-Sensitive Design (VSD). This article considers VSD as the prime candidate for implementing normative considerations into design. Its methodology is considered from a conceptual, analytical, normative perspective. The focus here is on the suitability of VSD for integrating moral values into the design of technologies in a way that joins in with an analytical perspective on ethics of technology. Despite its promising character, it turns out that VSD falls short in several respects: (1) VSD does not have a clear methodology for identifying stakeholders, (2) the integration of empirical methods with conceptual research within the methodology of VSD is obscure, (3) VSD runs the risk of committing the naturalistic fallacy when using empirical knowledge for implementing values in design, (4) the concept of values, as well as their realization, is left undetermined and (5) VSD lacks a complimentary or explicit ethical theory for dealing with value trade-offs. For the normative evaluation of a technology, I claim that an explicit and justified ethical starting point or principle is required. Moreover, explicit attention should be given to the value aims and assumptions of a particular design. The criteria of adequacy for such an approach or methodology follow from the evaluation of VSD as the prime candidate for implementing moral values in design.     

Christfried Jakob’s 1921 Theory of the Gnoses and Praxes as Fundamental Factors in Cerebral Cortical Dynamics

This study aims at reviving an important contribution by the pioneer neurobiologist and neurophilosopher Christfried Jakob (1866–1956) to the understanding of higher cortical functions. Jakob studied cortical dynamics at multiple levels by comparing gnoses and praxes and their corresponding pathological states, i.e. the agnosias and the apraxias. We herein provide a complete English translation of Jakob’s original Spanish article dating to 1921, and further consider some key points under the scope of the neuropsychological knowledge available then, and the research evidence available 90 years later.     

Is it a he or a she? Behavioral and computational approaches to sex categorization

Can people categorize the sex of neonate faces? Our experiment tested the sex categorization of neonate faces by adult participants. We used a set of 120 Caucasian faces (adults and 4-day-old neonates) that were presented just once to a large sample of participants. A computational model of low-level visual processing, based on Gabor filters, was used to explore the relation between spatial-frequency information and sex categorization. The results showed that participants were able to categorize the sex of the faces, but were less accurate with neonate (d' = 0.36, β = –.97) than with adult (d' = 3.02, β = –.93) faces. Moreover, faces were more frequently categorized as boys’ than girls’ faces. The computational model suggests that specific spatial-frequency channels carry most of the useful information for the categorization task. Overall, the findings reveal that subtle differences in neonate facial structure were enough to allow the sex categorization of neonate faces, although accuracy was low in both adults and the computational model of low-level visual processing.     

Complexity in object manipulation by Japanese macaques (Macaca fuscata): a cross-sectional analysis of manual coordination in stone handling patterns

Defined as a spontaneous stone-directed noninstrumental manipulative behavior, and comprised of multiple one-handed and (a)symmetrical/(un)coordinated two-handed patterns, stone handling (SH) is a good candidate for the study of complexity in object manipulation. We present a cross-sectional developmental analysis of SH complexity in Japanese macaques (Macaca fuscata), through the combined investigation of bimanuality, coordination, and symmetry in hand use. Bimanual SH patterns were more frequent than unimanual patterns. Among bimanual patterns, coordinated actions were more frequent than uncoordinated ones. We recorded five asymmetrical coordinated SH patterns with manual role differentiation, a form of hand use reminiscent of complex actions involving the use of tools in monkeys and apes. Bimanuality in SH was affected by body posture. Aging individuals performed less bimanual and less coordinated SH patterns than younger individuals. Our result on senescent males performing less bimanual patterns than senescent females was consistent with sex differences found in the late deterioration of complex manual movements in other species. Although some SH patterns represent a high degree of behavioral complexity, our results suggest that SH behavior is not as complex as tool-use or tool-manufacture in other nonhuman primates and hominids.     

La pratique physique,un moyen de circonscrire les effets délétères du confinement en milieu carcéral : impact d’un programme d’activités physiques sur la santé perçue et le bien-être psychologique de détenus

To be in prison consists in enduring the enticements of multiple stressors and constraints leading to an unpredictable and often uncontrollable situation. This generates serious health troubles and distress in the population living in prison. Physical Exercise (PE) is well acquainted for its benefits in terms of health and as such it seems reasonable to suggest its contribution in ameliorating life conditions among detainees, although the literature on the subject is quite scanty. The present report shows that moderate PE may contribute actively in ameliorating the health status. Notably perceived stress and other psychological factors are significantly improved in a small and particular population of detainees, sex offenders.     

Odorization of a novel object can influence infant's exploratory behavior in unexpected ways

Although much is known about the development of object exploration during infancy, it remains to be understood whether and how olfaction can influence infants' interactions with novel objects. To address these issues, sixteen infants aged 7-15 months were videotaped during two consecutive 5-min free play sessions with a scented or an unscented version of visually similar objects. Results indicate that adding an odor to a novel object influenced the infants' behavior: the infants exhibited more and longer manipulations and mouthing of the unscented object than of the scented object. The differential responsiveness to the scented, relative to the unscented, object was noted after a 2-min delay following test onset, suggesting that in the present conditions infants do not immediately detect or react to the added odor. It may be concluded that infants do detect an odorant added on a novel object, show odor-based discrimination of visually similar objects, and express withdrawal of the scented, relative to the unscented, object. The implications of these findings for understanding how infants use their senses, namely their olfactory sense, in early exploratory behavior are discussed.     

Response times seen as decompression times in Boolean concept use

This paper reports a study of a multi-agent model of working memory (WM) in the context of Boolean concept learning. The model aims to assess the compressibility of information processed in WM. Concept complexity is described as a function of communication resources (i.e., the number of agents and the structure of communication between agents) required in WM to learn a target concept. This model has been successfully applied in measuring learning times for three-dimensional (3D) concepts (Mathy and Bradmetz in Curr Psychol Cognit 22(1):41-82, 2004). In this previous study, learning time was found to be a function of compression time. To assess the effect of decompression time, this paper presents an extended intra-conceptual study of response times for two- and 3D concepts. Response times are measured in recognition phases. The model explains why the time required to compress a sample of examples into a rule is directly linked to the time to decompress this rule when categorizing examples. Three experiments were conducted with 65, 49, and 84 undergraduate students who were given Boolean concept learning tasks in two and three dimensions (also called rule-based classification tasks). The results corroborate the metric of decompression given by the multi-agent model, especially when the model is parameterized following static serial processing of information. Also, this static serial model better fits the patterns of response times than an exemplar-based model.     

Bypassing the central bottleneck after single-task practice in the psychological refractory period paradigm: Evidence for task automatization and greedy resource recruitment

In this research, the controversial issue of whether the central bottleneck can be bypassed through task automatization was investigated. To examine this issue, participants received six single-task practice sessions with an auditory-vocal task (low vs. high pitch). We then assessed dual-task performance using the analytically tractable psychological refractory period (PRP) paradigm, in which the highly practiced auditory-vocal task was presented as Task 2, along with an unpracticed visual-manual Task 1. The results provide evidence of bottleneck bypass for virtually all the participants (17 out of 20). Several converging tests suggest that the bottleneck reemerged, however, in a follow-up experiment with tasks presented in the opposite order (auditory-vocal Task 1 and visual-manual Task 2). One possible explanation is that tasks greedily recruit central resources when available, even though they can operate without central resources when unavailable.     

The role of impulsivity in actual and problematic use of the mobile phone

Several authors have investigated the risks arising from the growth in mobile phone use (e.g. debts incurred by young people). The aims of the present study are (1) to validate a new questionnaire assessing problematic mobile phone use: the Problematic Mobile Phone Use Questionnaire (PMPUQ), and (2) to investigate the relationships between the PMPUQ and the multi‐faceted construct of impulsivity. With these aims, 339 subjects were screened using the PMPUQ and the UPPS Impulsive Behaviour Scale (UPPS) which assesses four distinct components associated with impulsive behaviours (urgency, lack of premeditation, lack of perseverance and sensation seeking). The results showed that the PMPUQ has an acceptable fit and assesses four different dimensions of problematic mobile phone use (prohibited use, dangerous use, dependence, financial problems). While each facet of impulsivity played a specific role in mobile phones use, urgency appeared to be the strongest predictor of problematic use. Copyright © 2008 John Wiley & Sons, Ltd.     

Living up to high standards and psychological distress

We argue and demonstrate that setting high standards, an essential aspect of perfectionism, is not associated with maladaptive responses in and of itself. Rather, our findings suggest that people's responses to their perceptions that they consistently fail to meet their own standards are maladaptive. More importantly, in the present survey study (n = 293), we extend previous research by showing that low personal standards and the perception that others are imposing high standards on the self operate in concert to strengthen the link between perceived discrepancy and psychological distress. Furthermore, in support of our moderation‐mediation model, regression analyses provided evidence for the mediating role of generalised self‐efficacy beliefs. Copyright © 2008 John Wiley & Sons, Ltd.
