Aging and Spatial Navigation: What Do We Know and Where Do We Go?

Spatial navigation is a complex cognitive skill that is necessary for everyday functioning in the environment. However, navigational skills are not typically measured in most test batteries assessing cognitive aging. The present paper reviews what we know about behavioral differences between older and younger adults in navigational skill and reviews the putative neural mechanisms that may underlie these behavioral differences. Empirical studies to date clearly identify navigation as an aspect of cognitive function that is vulnerable to the aging process. The few functional and structural neuroimaging studies that speak to neurological correlates of these age-related differences point to the hippocampus, parahippocampal gyrus, posterior cingulate gyrus (retrosplenial cortex), parietal lobes and pre-frontal cortex as structures critically involved in age effects on navigation. Outstanding issues in the field are addressed and productive avenues of future research are suggested. Among these outstanding issues include the necessity of performing longitudinal studies and differentiating between hippocampal and extra-hippocampal contributions to aging in navigation. The field may also be advanced by empirical assessment of navigational strategies and investigations into the multisensory nature of navigation including assessing the relative contributions of visual, vestibular, and proprioceptive function to age differences in navigational skill.     

Awareness of Infants: What Do They,and We,Seek?

I study the biological foundations of human cultural intelligence, and how they are supported. I observe the development of human motives for agency, the emotions that evaluate what is discovered, and the ways interests and discoveries and feelings may be shared with others. Ed Tronick and I have been privileged to study infants closely over several decades in which ideas of the dynamic powers of the human mind have been transformed, principally by recording how infants act in intimate companionship with their mothers in the first year or two. Here I try to clarify the ways we have, for different purposes and in different environments, taken complementary routes to understanding the meaning of infant life. His responsibilities are clinical and occupied with supporting the mental health of both the infant and the mother, and the building of a strong affectionate trust for life with others. My task has been trying to understand the subtle creativity and aesthetic and moral principles that animate a widening circle of relationships for a child, and that lead to cultural learning that is rich and playful. Ed and I are lucky to be discovering what every infant wants, and privileged to be supporting pride in good company, while striving to guard against causes of despair and shame in young children and their families.     

Integrity and Honesty Testing: What Do We Know? How Do We Use It?

This selective review of integrity and honesty testing addresses two primary questions: ‘What do we know about honesty testing?’ and ‘How do we use what we know?’ Up-to-date information about test reliability, validity, and construct definition from recent reviews of the research literature in the USA is presented and interpreted. Relationships to other selection devices and personality measures are discussed, as well as how integrity tests fit into a multiple assessment selection system.     

Response: How Do We Know What We Know About the Amish and Other Minorities?

The appraisal by Cory Anderson, Joseph Donnermeyer, Jeffrey Longhofer, and Steven Reschly (hereafter, appraisers) highlights a methodological divide that is important to the study of the Amish and other ethnic or religious minorities. In my reply, I discuss how my work is rooted in a cultural analytic paradigm that differs from the appraisers’ methodological orientation. My reply includes a deconstruction of the appraisal and a discussion of its “shortcomings.” I conclude by showing how the discourse surrounding this appraisal raises important epistemological questions of how we understand human societies.     

Huntington Disease: Who Seeks Presymptomatic Genetic Testing,Why and What are the Outcomes?

The aims of this study were to: 1) quantify the characteristics of those seeking presymptomatic testing for HD, 2) identify their motivations for testing, 3) quantify the waiting times between the various steps within the testing process, and 4) quantify the outcomes of testing at a large state-wide genetic testing center in Australia. A review of medical charts for all referrals for presymptomatic testing of Huntington disease received over a 4 year period (2006–2010) was undertaken. A total of 152 cases met the study inclusion criteria; the mean age was 39 years, 46 % were male and 61 % underwent genetic testing. Of the males who were tested there was a non-significant trend towards having an affected mother vs father (62 %, p?=?0.09), whereas females tested were just as likely to have an affected mother or father. The most frequently cited reasons for seeking testing were “family planning”, “plan future”, and “need to know”. Some 11 % deferred testing following the psychological assessment. Of those at 50 % prior risk, 57.5 % tested positive; this was higher than expected and much higher than reported in other studies. The median times from referral to initial appointment, and then to results was 69 days and 144 days respectively. Overall, this review of medical charts shows the depth of information obtainable from routinely collected data and revealed that a high proportion of patients tested positive for HD at this centre.     

Why Do We Need to Know What the Public Thinks about Nanotechnology?

Public debate on nanotechnology is a large topic within governments, research agencies, industry and non-government organisations. But depending who you talk to the perception of what the public thinks about nanotechnology can be very varied. To define coherent policy and to invest in research and development that aligns with public preferences, needs more than just perceptions of public perceptions. Public attitude studies are vital in understanding what the public really think, but they need to go further than simplistic polling and should examine factors such as changes over time, drivers of attitude change, different attitudes to different applications and be supported by qualitative data. This paper summarises the findings of a three year tracking study of public attitudes towards nanotechnology, highlighting both concerns and aspirations for nanotechnology and discusses the impacts of that data on public engagement programs.     

What Do We Do Unconsciously? And How?

In this reply, we endorse Chartrand's (2005) taxonomy of conscious awareness for different stages of consumer decisions affected by environmental cues. In addition, we attempt to broaden the scope of this taxonomy by discussing its usefulness for consumer decisions in general. We generally support Simonson's (2005) claim that research based on consumers as conscious decision makers is indeed predictive of a wide variety of behavior. However, we also argue that the importance of consciousness should not be overstated. Conscious processes observed in a research laboratory are not representative of conscious processes in real life. The alternative model to describe effects of the environment on behavior by Janiszewski and van Osselaer (2005) may be useful to explain automaticity in goal‐directed behavior, but it poorly describes other automatic behaviors.     

Empirically Supported Treatments and Efficacy Trials: What Steps Do We Still Need to Take?

The Task Force on the Promotion and Dissemination of Psychological Procedures sought to identify scientifically supported treatments in order to espouse their use and improve client outcomes in therapy. Nevertheless, the gap between scientists and practitioners persists, and there still remain some limitations to the manner in which this goal is carried out. The criteria specifying whether a treatment qualifies as empirically supported are too lenient. The research used in the search for empirically supported treatments does not take into account the full literature base. Efficacy trials provide practitioners with limited information. This paper proposes means through which the field can improve its search for scientifically supported treatments. Alterations to the criteria that assess empirically supported treatments, greater research transparency and external validity, and collaboration between investigators and clinicians will allow the field of clinical psychology to better answer the question, “How can we most successfully treat this client?”     

Exploring Traumas in the Development of Talent: What Are They,What Do They Do,and What Do They Require?

It has recently been argued that performers benefit from trauma (i.e., memorable challenges) during development. To deepen knowledge in this area, we explored perceived traumas in the development of 20 senior-international performers with a multimethods, temporal-based design. Results showed that perceived traumas were primarily sports based, recognized from onset of investment, associated with immediately negative but ultimately positive impact, and negotiated through skills that were brought to, rather than generated by, these experiences. The findings provide an interesting contrast to messages in other early trauma-focused research and promote focus on the process and mechanisms of responding to and recovering from traumatic experiences.     

Spirituality in Occupational Therapy: Do We Practice What We Teach?

This mixed-method study examined the responses of 97 occupational therapists on the subject of spirituality in occupational therapy practice. The inclusion of spirituality into the Occupational Therapy Practice Framework (2008) implies that clinicians address spirituality as a component of client-centered practice. This research revealed a gap between education, theory, and practice as evidenced in the quantitative and qualitative data. Although occupational therapy is intended to be holistic, therapists require a more complete understanding of what spirituality is and what the role of the occupational therapist is when addressing spirituality in evaluation or treatment. The discussion of this research provides information for future occupational therapy educators and educational programs as they seek to incorporate the construct of spirituality into curricula.     

Authoritarian reactions to terrorist threat: Who is being threatened,the Me or the We?

Endorsement of authoritarian attitudes has been observed to increase under conditions of terrorist threat. However, it is not clear whether this effect is a genuine response to perceptions of personal or collective threat. We investigated this question in two experiments using German samples. In the first experiment (N = 144), both general and specific authoritarian tendencies increased after asking people to imagine that they were personally affected by terrorism. No such effect occurred when they were made to think about Germany as a whole being affected by terrorism. This finding was replicated and extended in a second experiment (N = 99), in which personal and collective threat were manipulated orthogonally. Authoritarian and ethnocentric (ingroup bias) reactions occurred only for people highly identified with their national ingroup under personal threat, indicating that authoritarian responses may operate as a group‐level coping strategy for a threat to the personal self. Again, we found no effects for collective threat. In both studies, authoritarianism mediated the effects of personal threat on more specific authoritarian and ethnocentric reactions. These results suggest that the effects of terrorist threat on authoritarianism can, at least in part, be attributed to a sense of personal insecurity, raised under conditions of terrorist threat. We discuss the present findings with regard to basic sociomotivational processes (e.g., group‐based control restoration, terror management) and how these may relate to recent models of authoritarianism.
