    • Personal Construct Theory,My Experience of Fruit & What people Chose to Care About Phil Turner
    • PERSONAL CONSTRUCT THEORY
    • • George Kelly – clinical psychologist• Created a theory of personality is predicated on one axiom: Man is a Scientist (Kelly, 1955)• That is, each of us tries to make sense of the world as we experience it, and we do this by constantly forming and testing hypotheses about the world.• By the time we are adults, we will have developed a very complex model of the world and our place in it: this model is, according to Kelly, our personality. 3
    • • The term construct is particularly well- chosen, because it reflects the concept’s dual role.• On the one hand, your constructs represent the view you have constructed about the world as you experienced it.• On the other hand, your constructs indicate how you are likely to construe the world as you continue to experience it. 4
    • • Our construct system is our history and our predisposition to perceive.• Kellys full theory of personal constructs is very detailed but its main points are: – Our construct systems make our world more predictable – Our construct systems can grow and change – Our construct systems influence our expectations and perceptions … 5
    • • Our construct system is our truth as we understand and experience it - nobody elses – A persons construct system represents the truth as they understand it. – Construct systems cannot be judged in terms of their objective truth - whatever objective means in the world of personal feelings and choices. 6
    • • Construct systems are not always internally consistent – People can and do live with a degree of internal inconsistency within their construct systems.• Kelly created a way of getting people to reveal their construct system and this is the Repertory Grid interviewing technique. 7
    • • The term repertory derives, of course, from repertoire - the repertoire of constructs which the person had developed.• Because constructs represent some form of judgement or evaluation, by definition they are bipolar. 8
    • • As they have become more widely used they have dropped their theoretical trappings and seen to be a matter of co-construction and exploration• And as such not suited to hypothesis testing 9
    • • Uses …• Rep grids have been used in knowledge elicitation for expert systems – Shaw and Gaines, 1987, 1992• Information system and HCI design – e.g. Dillon and McKnight 1990; – McCarthy and O’Connor 1998 – Turner, 2000, 2001, 2011• Job design (e.g. Hassard, 1987) 10
    • My experience of fruit Or, how to create a rep grid 11
    • • Select a set of elements.• The elements are concrete examples of the domain you wish to explore, in this instance, fruit.
    • • So working in pairs (interviewer & interviewee) we would aim to identify different types of fruit (which interviewee has eaten)• How many – 8 is a minimum starting point
    • • Triadic construct elicitation 14
    • • Write the name of each piece of fruit on a small piece of paper.• Taking the elements (fruit) in groups of three, and ask the question: ‘Can you tell me a way in which two of these are similar and which one is different … ?’• A typical response might be … – “these two are similar because they are easy to peel whereas this one one has rough skin” 15
    • • These are the constructs• Work through different combinations of fruit until you have generated (say) 8 different constructs
    • • Next step is to create a grid• Elements rated against constructs• A five point scale is usual 17

    • • Once entered into appropriate software the grid is subject to a PCA and visualised• http://repgrid.com/ 19
    • Grandfather’s iPod: investigating attachment to digital and non- digital artefacts Winner of best contribution award at ECCE 2011
    • • We treasure – or are attached to – artefacts of special significance – grandfather’s watch, baby’s hospital nametag, family photographs, jewelry, fountain pen…• Our lives are now populated with digital stuff• So… are people also attached to digital stuff• If so, how? 21
    • • Attachment: affective meaning beyond functionality (cf. Verbeek)• Related to ensoulment/heirloom status/enchantment• An artefact as an expression / extension of the self• Relevant to sustainable interaction design (SID) – if we are attached to objects we are less likely to dispose of them prematurely 22
    • • SID studies …• Key finding: people were less likely to be attached to digital items• However our informal surveys among students in 2009/10 suggested that this may be changing – digital artefacts had significant personal meaning – preserved even when long superseded 23
    • • Our study was in two stages• Stage 1 24
    • • Group of 8 postgraduate students• Method followed Fransella and Bannister (1977) – Each person chose 4 digital and 4 non-digital artefacts (elements) to which they felt some attachment – Using the triadic approach, at least eight constructs elicited from each participant• Then examined the entire set of constructs and identified the most common 25
    • • Aesthetically appealing - unremarkable• Received as a gift - bought this myself• Long term - short term• Reminds me of others - no association with other people• Personalised - generic• Exciting - everyday• Part of who I am - not really a part of me• Irreplaceable - easily replaced 26
    • • Stage 2 27
    • • 55 interviewees• Chose 4 digital and 4 non-digital possessions (elements) to which they were attached• Rated against the supplied constructs on a scale of 1 to 5• Results processed using Rep IV package 28
    • • Individual results analysed by examination of the resulting grids• But also selected the most common elements – those nominated by at least 20% of the interviewees• Consolidated all the data into a single set of repertory grids for the whole group – Using the modal construct rating for each element 29
    • • Elements elicited varied widely• Common non-digital possessions – Jewellery, photographs, items of furniture and clothing – But also cars, a crochet hook and a hot-water bottle.• Mobile phones, mp3 players, and laptops were the most common digital artefacts 30
    • • Individual data• Very varied patterns of attachment – No clear age/gender differences• Many instances of cherished non-digital artefacts – Jewellery, photos, some items of furniture• People are also attached to digital artefacts too – Phones, mp3 players, laptops• And may construe both kinds of artefact in similar ways 31
    • Jewellery box, necklace, iPod (99009692_3) female, thirty 32
    • 33
    • Teddy bear and laptop(08005823_3), female, early twenties 34
    • 35
    • My phone is part of me, male, mid-twenties 36
    • 37
    • Guitar, laptop & car, male, mid-twenties 38
    • 39
    • • Individual results analysed by examination of the resulting grids• But also selected the most common elements – those nominated by at least 20% of the interviewees• Consolidated all the data into a single set of repertory grids for the whole group – Using the modal construct rating for each element 40
    • • Some non-digital artefacts seem distinct in terms of the nature of attachment to them – Watches and jewellery, photos, wallets/purses• But the majority of both kinds of artefacts are perceived in similar way 41
    • The 12 most common artefacts 42
    • Aggregated Data 43
    • • Fairly even distribution of the digital and non- digital• The area containing the poles reminds me of others, irreplaceable, personalised, part of who I am and aesthetically pleasing encompasses photographs, computers, wallet/purse/bag, phon e and watch/jewellery• Towards the other poles of these constructs, we find books, digital camera, furniture and TV 44
    • Aggregated focus graph 45
    • • Close pairing between watch/jewellery and photographs, around 75%, also associated with wallet/purse/bag• Broader grouping at around 80%: games console, furniture, TV, digital camera, phone, laptop computer, mp3 player and clothing/footwear• Again, no neat division between the digital and non-digital• Grouping of constructs… – strong association between ‘long term’, ‘aesthetically pleasing’ and ‘part of who I am’ at just under 80% – weaker but still interesting association between ‘personal’, ‘irreplaceable’, ‘reminds me of others’ and ‘exciting’ 46
    • • The importance of the potential for personalisation/appropriation• The ‘hyper-personal’ – things which people would not part with - such as watches, jewellery and photographs• Small objects - mobile phones, jewellery and MP3 players - carried close to the body may be intimately associated with the self 47
    • • In some cases, emotional attachment is associated with the artefact being a gift – which reminds the owner of the giver• In Verbeek’s terms, people are attached to digital things themselves – The desktop computer as ‘part of who I am’ in the same way as photographs or jewellery – A laptop is cherished in the same way as a teddy bear 48
    • • We expected greater attachment to the non-digital – Despite smart design, smart advertising and a smart brand, digital objects are commodities, in Borgmann’s sense (Borgmann, 1984) – Grandfather’s watch is inscribed with meaning - it is a thing – Borgmann argues that commodities are “highly reduced entities and abstract in the sense that within the overall framework of technology they are free of local and historical ties’ – In contrast, things, “engage us in so many and subtle ways that no quantification can capture them”• Contrary to our expectations and Borgmann’s eloquence we found no evidence to support this position 49
    • • Digital artefacts may be ensouled• They do not pose unique design problems but are part of a continuum of artefacts which may be cherished or disposable• These socially constructed, treasured artefacts may act as boundary objects (Star 1989) between generations 50
    • • Digital and non-digital objects both have the potential to be things rather than commodities (Borgmann). Or in Verbeek’s terms, to have meaning beyond functionality• All part of the domestic landscape of stuff 51
