Imagining Fictional Faces

Fictional characters loom large in cultural traditions throughout recorded history, and are commonly portrayed in literature and visual arts. The persistence of these traditions demonstrates that information concerning the appearance of fictional characters - including facial appearance - can be preserved and shared among individuals. The current thesis is an attempt to understand the cognitive processes underlying mental imagery for fictional faces. It was already established that mental representations of real faces undergo qualitative change as visual exposure leads to familiarity. Fictional faces are never seen directly, though they may be represented in various ways. If fictional faces can acquire the psychological hallmarks of familiar faces, this would suggest alternative routes to face learning, besides natural visual exposure. To date however, this possibility has been largely ignored. The experiments in this thesis addressed learning of fictional faces by examining familiarity effects for fictional faces, and by assessing the consequences of reading descriptions on mental imagery for fictional characters. The main findings indicate that face representations and face learning may be more adaptable than previously assumed, accommodating photographic images, different types of drawings, and written descriptions. All of these representations can be quantified and compared using the common currency of social inference ratings. Written descriptions of physical and character attributes both contribute to mental imagery for faces, and these complementary types of information can converge on specific facial identities. As well as enriching our psychological understanding of face processing, the current thesis forms a bridge between the scientific study of faces, and portrayals of faces in the arts

CONSORT to community: translation of an RCT to a large-scale community intervention and learnings from evaluation of the upscaled program

Abstract Background Translation encompasses the continuum from clinical efficacy to widespread adoption within the healthcare service and ultimately routine clinical practice. The Parenting, Eating and Activity for Child Health (PEACH™) program has previously demonstrated clinical effectiveness in the management of child obesity, and has been recently implemented as a large-scale community intervention in Queensland, Australia. This paper aims to describe the translation of the evaluation framework from a randomised controlled trial (RCT) to large-scale community intervention (PEACH™ QLD). Tensions between RCT paradigm and implementation research will be discussed along with lived evaluation challenges, responses to overcome these, and key learnings for future evaluation conducted at scale. Methods The translation of evaluation from PEACH™ RCT to the large-scale community intervention PEACH™ QLD is described. While the CONSORT Statement was used to report findings from two previous RCTs, the REAIM framework was more suitable for the evaluation of upscaled delivery of the PEACH™ program. Evaluation of PEACH™ QLD was undertaken during the project delivery period from 2013 to 2016. Results Experiential learnings from conducting the evaluation of PEACH™ QLD to the described evaluation framework are presented for the purposes of informing the future evaluation of upscaled programs. Evaluation changes in response to real-time changes in the delivery of the PEACH™ QLD Project were necessary at stages during the project term. Key evaluation challenges encountered included the collection of complete evaluation data from a diverse and geographically dispersed workforce and the systematic collection of process evaluation data in real time to support program changes during the project. Conclusions Evaluation of large-scale community interventions in the real world is challenging and divergent from RCTs which are rigourously evaluated within a more tightly-controlled clinical research setting. Constructs explored in an RCT are inadequate in describing the enablers and barriers of upscaled community program implementation. Methods for data collection, analysis and reporting also require consideration. We present a number of experiential reflections and suggestions for the successful evaluation of future upscaled community programs which are scarcely reported in the literature. Trials registration PEACH™ QLD was retrospectively registered with the Australian New Zealand Clinical Trials Registry on 28 February 2017 (ACTRN12617000315314)
