Early Huntington's disease affects movements in transformed sensorimotor mappings

This study examined the effect of transformed visual feedback on movement control in Huntington's disease (HD). Patients in the early stages of HD and controls performed aiming movements towards peripheral targets on a digitizing tablet and emphasizing precision. In a baseline condition, HD patients were slower but showed few precision problems in aiming. When visual feedback was inverted in both vertical and horizontal axes, patients showed problems in initial and terminal phases of movement where feedback is most critical. When visual feedback was inverted along a single axis as in a mirror-inversion, HD patients showed large deviations and over-corrections before adaptation. Adaptation was similar in both groups. These results suggest that HD impairs on-line error correction in novel movements.     

Adaptation in Modern Times

Since the beginning of Christian mission, adaptation to local cultures (later called acculturation or inculturation) has been the main factor in mission failure or success. Placide Tempels is considered a pioneer of adaptation in modern times. He was a Flemish Franciscan missionary in Congo from 1933 to 1962 (with two breaks) and is well known for his adaptation to the Bantu worldview. Referring to spiritual and intellectual adaptation, the paper will answer the following questions: Was the adaptation of Placide Tempels successful? If it was or was not, why and in what way? The analysis will be linked to William Biernatzki's theory of root paradigms and meanings. To conclude, a connection will be made to the process of adaptation in international mission organizations today.     

Behavioural adaptation to driving with an adaptive cruise control (ACC)

The present paper describes a study that aims at assessment of driver behaviour in response to new technology, particularly Adaptive Cruise Control Systems (ACCs), as a function of driving style. In this study possible benefits and drawbacks of Adaptive Cruise Control Systems (ACCs) were assessed by having participants drive in a simulator. The four groups of participants taking part differed on reported driving styles concerning Speed (driving fast) and Focus (the ability to ignore distractions), and drove in ways which were consistent with these opinions. The results show behavioural adaptation with an ACC in terms of higher speed, smaller minimum time headway and larger brake force. Driving style group made little difference to these behavioural adaptations. Most drivers evaluated the ACC system very positively, but the undesirable behavioural adaptations observed should encourage caution about the potential safety of such systems.     

Shifting the focus from what to why

After 4 decades of research on infant behavior and development, the time has come to shift our focus from What infants do to Why they do it when they do—to move beyond the single-minded search for mechanism and to consider the larger question of function. Infants are not merely incomplete adults who simply get better with age, but they are different organisms altogether, perfectly adapted at every point in ontogeny. For this reason, answers to the Why question will necessarily build upon an evolutionary framework that reflects the infant's changing “occupations” or ecological niches. Through this pursuit, infancy researchers will develop a more integrative science and a greater sense of community.     

Introduction to the special issue on “psychological research and practice in organ transplantation”

This paper provides a brief overview of articles in this Special Issue on Psychological Research and Practice in Organ Transplantation. The articles provide empirical information on the psychological adaptation of transplant candidates and recipients, as well as addressing the myriad ethical and clinical issues evident in the field of organ transplantation. Heart, liver, lung, kidney, and bone marrow transplantation for children and adults has increased in frequency in recent years, and the articles address the need for more sophisticated and comprehensive assessment of psychological concomitants. The Guest Editor's Top Ten list of research needs which transplantation psychologists might further address is discussed in this article.     

Effects on fathers of children with down syndrome

This study investigated research evidence for eight assertions found in the literature about effects on fathers of children with disabilities. Eighty-seven fathers of children with Down syndrome completed questionnaire instruments designed to measure demographic variables, adaptation, stress, personality, social support and marital functioning. The results provided little support for most of the assertions. It is concluded that the existing literature provides a somewhat erroneous perspective of the experiences of such fathers. These findings reinforce the need for further research specifically with fathers of children with mental retardation.     

Assessment of proneness to distraction: English adaptation and validation of the Attention-Related Driving Errors Scale (ARDES) and cross-cultural equivalence

Prior research developed the Attention-Related Driving Errors Scale (ARDES), a 19-item questionnaire aimed at evaluating the drivers’ predisposition to attentional error, and also provided validity evidence of ARDES measures across two countries: Argentina and Spain. In the current work we adapt the Spanish version of the ARDES to the English language and the culture, traffic regulations and driving habits of the UK, and then provide new evidence of the cross-cultural equivalence of the scale. First, an improved forward and backward translation design was used to translate the Spanish ARDES into English. A committee-approach review process was also performed during the translation phase to guarantee that the English ARDES was the most appropriate to reflect the language, culture, traffic regulations and driving habits of the UK. Second, the adapted questionnaire was tested on 301 British drivers to inspect its psychometric properties and study the relationships between the ARDES-UK and different socio-demographic variables. In agreement with the previous literature, the results of the factor analysis confirmed a single factor and accounting for 33.84% of the variance. Cronbach’s alpha was equal to .89. The observed pattern of relationships of the scores and the different socio-demographic variables was consistent with previous evidence and support the validity of the adapted questionnaire. For example, the ARDES-UK scores were significantly different between drivers reporting and not reporting traffic accidents with material damage. To conclude with, the translation design and the resulting psychometric suggest the validity of ARDES-UK measures for evaluating the British drivers’ predisposition to attentional error. In addition, the evidence in the current work supports the hypothesis of the cross-cultural stability of the scale across Spain and the UK.     

How shall we all live together?: Meta-analytical review of the mutual intercultural relations in plural societies project

Living together in culturally plural societies poses numerous challenges for members of ethnocultural groups and for the larger society. An important goal of these societies is to achieve positive intercultural relations among all their peoples. Successful management of these relations depends on many factors including a research-based understanding of the historical, political, economic, religious and psychological features of the groups that are in contact. The core question is ‘how we shall we all live together?’ In the project reported in this paper (Mutual Intercultural Relations in Plural Societies; MIRIPS), we seek to provide such research by reviewing three core psychological hypotheses of intercultural relations (multiculturalism, contact and integration) in 21 culturally plural societies. The main goal of the project is to evaluate these hypotheses across societies within the MIRIPS project in order to identify if there are some basic psychological principles that underlie intercultural relations panculturally. If there are, the eventual goal is to employ the findings to propose some policies and programmes that may improve the quality of intercultural relationship globally. An internal meta-analysis using the MIRIPS project data showed that the empirical findings from these societies generally support the validity of the three hypotheses. Implications for the development of policies and programmes to enhance the quality of intercultural relations are discussed.
