Explanations for variation in cognitive ability : behavioural ecology meets comparative cognition

Sara Shettleworth has played a defining role in the development of animal cognition and its integration into other parts of biology, especially behavioural ecology. Here we chart some of that progress in understanding the causes and importance of variation in cognitive ability and highlight how Tinbergen's levels of explanation provide a useful framework for this field. We also review how experimental design is crucial in investigating cognition and stress the need for naturalistic experiments and field studies. We focus particularly on the example of the relationship among food hoarding, spatial cognition and hippocampal structure, and review the conflicting evidence for sex differences in spatial cognition. We finish with speculation that a combination of Tinbergen and Shettleworth-style approaches would be the way to grapple with the as-yet unanswered questions of why birds mimic heterospecifics.

A method for tracking rats in a complex and completely dark environment using computerized video analysis

The automated tracking of rodents in open field environments has become a standard laboratory technique for the investigation of the effects of drugs, novel therapeutic interventions and genetic mutations on behavior. Here, we develop an extension of this technique that permits tracking in full darkness through a complex (‘enriched’) environment comprising naturalistic structures such as tunnels and hides. To eliminate unwanted light reflections and tape noise, we developed a unique video filter that combines the advantages of differential and non-differential filtering. This filter enabled the tracking of albino rats against a relatively dark background to an accuracy of approximately 97% compared to hand tracking of the same animal, irrespective of whether the rat was inside a hide box or tunnel or out in the open field. The system as a whole can be easily deployed using standard PCs and inexpensive infrared cameras and lights.

Changing Aristotle's mind and world : critical notes on McDowell's Aristotle

Aristotle’s Nicomachean Ethics is central to John McDowell’s classic Mind and World. In Lectures IV and V of that work, McDowell makes three claims concerning Aristotle’s ethics: first, that Aristotle did not base his ethics on an externalist, naturalistic basis (including a theory of human nature); second, that attempts to read him as an ethical naturalist are a modern anachronism, generated by the supposed need to ground all viable philosophical claims on claims analogous to the natural sciences; and third, that a suitably construed Aristotelian conception of “second nature” can form the basis of a viable contemporary philosophy of mind, world, and normativity. This paper challenges each of these three claims. Aristotle’s ethics, we will claim alongside Terence Irwin, Bernard Williams, Philippa Foot, and many premodern commentators, is based in the kind of physics, metaphysics, and metaphysical biology that McDowell says it cannot be. Historically, we will argue that McDowell’s argument that Aristotle’s ethical reasoning is “autonomous” or “self-standing” is distinctly modern, citing evidence from the leading medieval commentators on the Nicomachean Ethics. The felt need to which McDowell responds, of reading Aristotle’s ethical or political thought as wholly non-metaphysical, arises from out of the successes of the natural sciences in the modern world, which he agrees discredit the Aristotelian, teleological account of nature. In the final part of the paper, we propose that McDowell’s account of normativity, rooted in the non-metaphysical “second nature” he reads into Aristotle, we will contend, is as it stands inescapably relativistic. On a different note, we need also to recognize, as McDowell does not, that this is a new Aristotle, one shaped by our requirements and space of reasons, not the mind and world of the Greek Philosopher himself.

Anxiety online - a virtual clinic : preliminary outcomes following completion of five fully automated treatment programs for anxiety disorders and symptoms

Background : The development of e-mental health interventions to treat or prevent mental illness and to enhance wellbeing has risen rapidly over the past decade. This development assists the public in sidestepping some of the obstacles that are often encountered when trying to access traditional face-to-face mental health care services. Objective : The objective of our study was to investigate the posttreatment effectiveness of five fully automated self-help cognitive behavior e-therapy programs for generalized anxiety disorder (GAD), panic disorder with or without agoraphobia (PD/A), obsessive–compulsive disorder (OCD), posttraumatic stress disorder (PTSD), and social anxiety disorder (SAD) offered to the international public via Anxiety Online, an open-access full-service virtual psychology clinic for anxiety disorders. Methods : We used a naturalistic participant choice, quasi-experimental design to evaluate each of the five Anxiety Online fully automated self-help e-therapy programs. Participants were required to have at least subclinical levels of one of the anxiety disorders to be offered the associated disorder-specific fully automated self-help e-therapy program. These programs are offered free of charge via Anxiety Online. Results : A total of 225 people self-selected one of the five e-therapy programs (GAD, n = 88; SAD, n = 50; PD/A, n = 40; PTSD, n = 30; OCD, n = 17) and completed their 12-week posttreatment assessment. Significant improvements were found on 21/25 measures across the five fully automated self-help programs. At postassessment we observed significant reductions on all five anxiety disorder clinical disorder severity ratings (Cohen d range 0.72–1.22), increased confidence in managing one’s own mental health care (Cohen d range 0.70–1.17), and decreases in the total number of clinical diagnoses (except for the PD/A program, where a positive trend was found) (Cohen d range 0.45–1.08). In addition, we found significant improvements in quality of life for the GAD, OCD, PTSD, and SAD e-therapy programs (Cohen d range 0.11–0.96) and significant reductions relating to general psychological distress levels for the GAD, PD/A, and PTSD e-therapy programs (Cohen d range 0.23–1.16). Overall, treatment satisfaction was good across all five e-therapy programs, and posttreatment assessment completers reported using their e-therapy program an average of 395.60 (SD 272.2) minutes over the 12-week treatment period. Conclusions : Overall, all five fully automated self-help e-therapy programs appear to be delivering promising high-quality outcomes; however, the results require replication.

The use of video recording in professional development of teachers and teacher educators in Indonesia

Design-based research has gained currency in educational research over the past decade due to its strength to bridge the divide between theoretical research and educational practice in naturalistic settings. Design based approaches involve a process of designing mathematical tasks, observing the enacted design in classrooms and reflecting on the process from analysing the classroom artifacts. Video plays a central role in supporting teachers and teacher educators to study and reflect on students’ mathematical thinking and in capturing the dynamic of classroom teaching and learning process.

This chapter will examine and analyse practitioner’s lenses in capturing the dynamic and complexity of classroom mathematical learning using video segments, and classroom artifacts including digital photos of classroom moments and students’ work. Practitioners’ lenses are taken as a window to capture key teaching and learning moments from the lessons. Analysis of this selection of these video segments along with other classroom artifacts based on practitioners’ lenses provide insights into practitioners’ views on key teaching and learning moments in mathematics lessons.

Impact of an active video game on healthy children’s physical activity

OBJECTIVE: This naturalistic study tests whether children receiving a new (to them) active video game spontaneously engage in more physical activity than those receiving an inactive video game, and whether the effect would be greater among children in unsafe neighborhoods, who might not be allowed to play outside.

METHODS: Participants were children 9 to 12 years of age, with a BMI >50th percentile, but <99th percentile; none of these children a medical condition that would preclude physical activity or playing video games. A randomized clinical trial assigned children to receiving 2 active or 2 inactive video games, the peripherals necessary to run the games, and a Wii console. Physical activity was monitored by using accelerometers for 5 weeks over the course of a 13-week experiment. Neighborhood safety was assessed with a 12 item validated questionnaire.

RESULTS: There was no evidence that children receiving the active video games were more active in general, or at anytime, than children receiving the inactive video games. The outcomes were not moderated by parent perceived neighborhood safety, child BMI z score, or other demographic characteristics.

CONCLUSIONS: These results provide no reason to believe that simply acquiring an active video game under naturalistic circumstances provides a public health benefit to children.

The effects of training on performance and performance-related states in individual elite athletes : a dynamic approach

There are difficulties undertaking controlled training studies with elite athletes. Thus, data from non-elite performers are often presented in scientific journals and subsequently used to guide general training principles. This information may not be transferable or specific enough to inform training practices in an individual elite athlete. However, the nature of athletic participation at elite levels provides the opportunity to collect training data, performance-related variables, and performance data of elite athletes over long periods. In this paper, we describe how dynamic linear models provide an opportunity to use these data to inform training. Data from an elite female triathlete collected over a 111-day training period were used to model the relationship between training and self-reported fatigue. The dynamic linear model analysis showed the independent effects of the three modes of triathlon training on fatigue, how these can change across time, and the possible influence of other unmeasured variables. This paper shows the potential for the use of dynamic linear models as an aid to planning training in elite athletes.

Understanding of mental states in later childhood: an investigation of theory of mind in autism spectrum disorder and typical development with a novel task

The developmental trajectories of Theory of Mind (ToM) in later childhood and into adolescence have not been thoroughly investigated, partly due to a lack of sensitive paradigms that can chart development in typical populations or in individuals with a core deficit in ToM, such as those with autism spectrum disorder (ASD). The present study assessed understanding of emotions, beliefs, and intentions using both an established ToM task (Baron‐Cohen et al., 2001) and the more recently developed Comic Strip Task (CST; Cornish et al., 2010). Participants comprised 12 typically-developing (TD) children (mean age: 12·0 years, range: 9·9‐14·8 years) and 12 high-functioning children with ASD (mean age: 11·0 years, range: 9·1‐13·6 years). Results indicated that the ASD group were not impaired on any of the ToM tasks relative to TD children. It was concluded that although children with high-functioning ASD appear to develop basic ToM skills, they do not generalize these to naturalistic situations. The comic-strip paradigm is suggested as a promising way to approach the measurement of ToM across childhood in typical children and those with ASD.

State body dissatisfaction and social interactions : an experience sampling study

To date, there has been limited empirical scrutiny of the correlates and consequences of day-to-day state body dissatisfaction fluctuations within naturalistic contexts. We used ecological momentary assessment (a form of naturalistic observation) to evaluate whether state body dissatisfaction was concurrently and/or prospectively associated with occurrence and quality of social interactions. Women (N = 121), aged 18 to 40, completed a brief trait-based survey and then nominated a 7-day period within which to receive seven text messages daily, at random intervals, prompting them to complete measures of body dissatisfaction at that moment. If they were currently or had recently engaged in social interactions, they were also asked to fill out questions rating the quality of these interactions (operationalized in terms of enjoyment of, and control in, the interaction). Findings suggest that the relationship between state body dissatisfaction and aspects of social interactions is complex and may vary over time. Cross-sectionally, state body dissatisfaction and social interaction quality were negatively associated. Prospectively, however, body dissatisfaction predicted subsequent avoidance of social interactions. Interestingly, when women chose to avoid social interactions, their body dissatisfaction worsened, yet when they did engage in social interactions, they reported improved body satisfaction. Importantly, the links between state body dissatisfaction and social interactions may be moderated by body mass index and trait body satisfaction levels. Potential mechanisms underlying the association between state body dissatisfaction and quality and quantity of social interactions are discussed, and future research avenues are proposed to further understand their inter-relation.

Patient participation in quality pain management during an acute care admission

The objective of the study was to explore patient participation in the context of pain management during a hospital admission for a cardiac surgical intervention of patients with cardiovascular disease. This is a single-institution study, with a case-study design. The unit of analysis was a cardiothoracic ward of a major metropolitan, tertiary referral hospital in Melbourne, Australia. Multiple methods of data collection were used including preadmission and predischarge patient interviews (n=98), naturalistic observations (n=48), and focus group interviews (n=2).

Patient participation in medication safety during an acute care admission

Background : Patient participation in medication management during hospitalization is thought to reduce medication errors and, following discharge, improve adherence and therapeutic use of medications. There is, however, limited understanding of how patients participate in their medication management while hospitalized.Objective : To explore patient participation in the context of medication management during a hospital admission for a cardiac surgical intervention of patients with cardiovascular disease.Design : Single institution, case study design. The unit of analysis was a cardiothoracic ward of a major metropolitan, tertiary referral hospital in Melbourne, Australia. Multiple methods of data collection were used including pre-admission and pre-discharge patient interviews (n = 98), naturalistic observations (n = 48) and focus group interviews (n = 2).Results : All patients had changes made to their pre-operative cardiovascular medications as a consequence of surgery. More patients were able to list and state the purpose and side-effects of their cardiovascular medications at pre-admission than prior to discharge from hospital. There was very little evidence that nurses used opportunities such as medication administration times to engage patients in medication management during hospital admission.Discussion and Conclusions : Failure to engage patients in medication management and provide opportunities for patients to learn about changes to their medications has implications for the quality and safety of care patients receive in hospital and when managing their medications once discharged. To increase the opportunity for patients to participate in medication management, a fundamental shift in the way nurses currently provide care is required.

Family strategies to support and develop resilience in early childhood

Early childhood is an important time for the development of resilience. A recently completed study has followed three cohorts of resilient children and young people living in disadvantaged areas in Victoria, Australia, through different transitions in their educational careers. This paper focuses on the early childhood cohort, where we have followed children from kindergarten/preschool into primary school. Using data gathered primarily through interviews with parents (mothers in each case), this paper presents a qualitative naturalistic sub-study that used deductive thematic analysis to explore the different strategies used by families to support their child's resilience. Our findings highlight that resilience was a salient concept for all of the mothers in the study and each mother articulated a range of strategies they used within the family to try and support their child's development and resilience. These strategies were constrained by the settings in which the families lived. © 2014 © 2014 TACTYC.

Evolution of adolescent mental health in a rapidly changing socioeconomic environment: a review of mental health studies in adolescents in India over last 10 years

Background: Significant changes in the economic, familial and social support aspects in India have occurred in recent times, making it an interesting naturalistic setting to observe the effects of a dynamic socioeconomic environment on behavioral and emotional disorders in adolescents. Objective: This systematic review attempts to synthesize and evaluate the available evidence on mental health disorders and interventions in adolescents in India in last 10 years as well as identify conceptual trends and methodological lacunae in these studies. Method: A systematic search of electronic databases was performed in March 2014 and 27 school and community based studies evaluating behavioral problems, psychiatric morbidity, stress, suicide-related behaviors, depression, anxiety, aggression, self concept in adolescents in India were reviewed. Conclusion: There is a wide variation in the reported prevalence of psychiatric morbidity and behavioral problems in Indian adolescents. Some of the risk and protective factors are similar to those identified by other International studies in this age group. These include female gender, academic difficulties, parental fights, strained familial relationships, school absenteeism, school dropout and other school related factors. However, there are certain variables that appear to be context specific and need further investigation. These are mother's working status, studying in Government institutions or belonging to a nuclear family as risk factors and praying as a coping skill, parental involvement as a protective factor for psychiatric disorders. The suspected upward trend in the psychiatric morbidity in this age group needs more studies to be established. © 2014 Elsevier B.V.

Innovation showcase : Performing beginning teachers' 'firsts'

Teacher identity work emphasises it is important beginning teachers understand their professional identity as something shifting, fluid and emerging – not fixed. These and other water metaphors – such as ‘washout’, ‘sink or swim’, and ‘thrown in the deep end’ – are often used to describe beginning teachers’ experiences. Such words and metaphors portray the fluid and unpredictable nature of identity transformation, while also highlighting that beginning teachers in particular find this transformation difficult, resulting in high levels of teacher attrition in the early years.Throughout 2011 twelve beginning teachers shared their experiences of identity transformation in semi-structured interviews with the researcher. Their interview data was analysed and scripted into an ethnographic performance, examining how ‘first’ experiences shape teachers’ future practice and identity. This presentation includes excerpts from the performance ‘The First Time’, and expands on the methodological approaches taken to generate data and knowledge that reflects the fluid and unpredictable nature of teachers’ identity. This eclectic approach combined an understanding of the self (Mead, 1934) with non-naturalistic theatrical conventions used to form the data into an ethnographic performance. The research is framed within a practice theory approach (Schatzki, 2001) with a focus on practices situated within a particular time and place.The research findings focus on the importance of developing creativity and flexibility as key beginning teacher attributes in order to ‘swim with the current’, and to counter the negative preconceptions beginning teachers are told to expect as rites of passage upon entering the profession. The outcomes of my research have implications for teacher educators and in-service teachers in assisting beginning teachers to negotiate the waters of an ever-changing profession.
