Displacement of Self-Continuity: An Illuminative Heuristic Inquiry Into Identity Transition in an Allegorical Animation
No full textThis practice-led artistic research considered how a fictional allegory might be employed to examine issues of acculturation, displacement and identity transition. Using the story of a refugee family, the study explored the implications of identity reconstruction inside the body of a new culture.
The narrative of Stella was designed to serve as a provocative vehicle for considering the social implications of identity loss and transition. The practice was provided as a screenplay, a post-visualisation document and an indicative trailer supported by a 45,000 word exegesis.
The project was shaped by an heuristic inquiry that merged existing writing on the methodology with an unique Persian illuminationist ontological and epistemological orientation. Inside the resulting framework a relationship elevated both the self (the writer/director/animator) and the body of knowledge, through the process of making and reflection.
Beyond its contribution to understanding processes and implications of acculturation, displacement and identity transition, the project’s technological significance also lay in its propensity to extend the application and demonstrate the potential of performance capture (using motion capture technology), 3D laser scanning and photogrammetry
Cognitive and brain markers in presymptomatic genetic behavioural variant frontotemporal dementia: a case-control study
No full textThis thesis investigated presymptomatic family members of a kindred carrying the MAPT genetic variant for behavioural variant frontotemporal dementia (bvFTD-MAPT), who are part of the FTDGeNZ study, with the aim of identifying early behavioural, cognitive and neural changes in gene-positive family members.
Study one aimed to characterise signs of neuropsychological and behavioural changes in presymptomatic bvFTD-MAPT, with the novel corollary of exploring episodic memory (EM), autobiographical memory (AM) and episodic future thinking (EFT) to determine whether a ‘true’ medial temporal-based memory deficit is an early feature. Using an age-matched case-control design, participants were stratified into ‘younger’ (40 years old; cases n=3; controls n=8) groups. Results highlight heterogeneous patterns of performance across gene-positive cases. Reduced performance emerged in domains of attention and processing speed, and language/semantic capacity. Findings were not consistent enough to indicate EM, AM and EFT were early markers of change, nor did we observe a true medial temporal-based memory deficit.
Study two sought to identify the earliest neural changes occurring in presymptomatic bvFTD-MAPT by measuring grey matter volume and cortical thickness in a case-control design, covarying for age (cases n=5; controls n=16). Reductions in regions varied across cases, with more extensive reductions in some cases than others. Volumetric and cortical thickness findings showed the amygdala, insula, inferior/superior temporal gyrus most frequently implicated. Medial temporal lobe changes were not as prominent as predicted.
Study three used fMRI to measure neural activity during AM and EFT compared to semantic memory, to determine if differences in activation could be observed in the core network supporting episodic autobiographical thinking in presymptomatic bvFTD-MAPT. Results of this case-control design, covarying for age (cases n=5; controls n=16) showed three of five cases activated a similar spatio-temporal pattern as the control group. The remaining two cases deviated from the control group’s pattern of activation, one showing a compensatory pattern of activation, and the other, dedifferentiation.
Combined, the three studies in this thesis present a nuanced examination of the cognitive, behavioural, and neural characteristics of a presymptomatic bvFTD-MAPT kindred, and contribute to understanding the bvFTD-MAPT disease course
Who am I: Sense of self in individuals with sudden-onset episodic amnesia
No full textFull Text is available to authenticated members of The University of Auckland only.Although there is an indisputable relationship between autobiographical memory (AM) and sense of self (SOS), there is still debate concerning the role of episodic and semantic forms of AM in SOS, both in the present moment and over time. In order to assess how episodic AM impairment may differentially affect aspects of SOS, this thesis aimed to examine the SOS of three individuals with varying degrees of sudden-onset episodic amnesia, which is characterised by impaired episodic AM and relatively preserved semantic AM. First, the cases were compared to matched healthy controls on the Autobiographical Interview (AI) to assess the degree of episodic AM impairment. Second, to assess different aspects of SOS we used fine-grained measures that capture various dimensions of self-concept (i.e., objective SOS in the present moment), as well as self continuity, specifically phenomenological continuity (i.e., subjective SOS over time), and two forms of semantic continuity (i.e., objective SOS over time): temporally-extended trait self-knowledge and narrative continuity. Additionally, we measured retrieval of turning point events (i.e., specific events that impact one’s life), since previous research suggest these may be related to coherence of one’s life narrative. Overall, the cases’ impairments in self-concept and all forms of continuity differed based on the degree of their episodic AM impairment. The case with the least amount of episodic AM impairment exhibited intact self-concept and phenomenological continuity, while the two cases with the more severe episodic AM impairments exhibited reductions in both their strength of self-concept and phenomenological continuity. Furthermore, while all three cases exhibited accurate current self-knowledge, one showed reduced accuracy of temporally-extended trait self-knowledge. While the cases were able to identify turning point events, in two of the cases, the quality of their turning point events differed from controls. Lastly, although all three cases exhibited reduced narrative continuity to some extent, they all maintained their ability to perceive themselves as the same person over time (i.e., diachronic unity). Crucially, the current study demonstrates although episodic AM affects one’s SOS in complex ways, one’s SOS can still persist despite these impairments
Remembering the Past and Imagining the Future in the Elderly
No full textRecent research has demonstrated commonalities between remembering past events and imagining future events. Behavioral studies have revealed that remembering the past and imagining the future depend on shared cognitive processes, whereas neuropsychological and neuroimaging studies have shown that many of the same brain regions are involved in both remembering the past and imagining the future. Here, we review recent cognitive and neuroimaging studies that examine remembering the past and imagining the future in elderly adults. These studies document significant changes in elderly adults’ capacities to imagine future events that are correlated with their memory deficits; most strikingly, older adults tend to remember the past and imagine the future with less episodic detail than younger adults. These findings are in line with the constructive episodic simulation hypothesis [Schacter and Addis: Phil Trans R Soc B 2007;362:773-786], which holds that that past and future events draw on similar information and rely on similar underlying processes, and that episodic memory supports the construction of future events by extracting and recombining stored information into a simulation of a novel event. At the same time, however, recent data indicate that non-episodic factors also contribute to age-related changes in remembering the past and imagining the future. We conclude by considering a number questions and challenges concerning the interpretation of age-related changes in remembering and imagining, as well as functional implications of this research for everyday concerns of older adults.PsychologyAccepted Manuscrip
A Comparative Analysis of the Equity Outcomes in Three Sugarcane–Ethanol Systems
No full textThis article identifies equity outcomes associated with three biofuel systems in Brazil, Ethiopia, and Guatemala. Acknowledging that winners and losers are socially and politically generated, the article identifies some of the factors behind the distribution of winners and losers along different stages of three sugarcane–ethanol supply chains. Analyzing the outcomes for equity within each case study reveals an uneven distribution that, we argue, is related to the procedure and structure of the given sugarcane–ethanol system, and the recognition of the impacts on different actors within those structures. Increasing equity in sugarcane–ethanol systems will require greater openness in decision-making processes, in order that multiple voices are taken into account in the promotion, production, and consumption of biofuels—particularly those of smaller and less powerful actors
