WHY?
Immersion / Fantasy [V]
“it’s like I become the cuddle toy in the game” [C]
“It’s soft and cute” [A]
“I like the cuddle toy” [preference]

Testing these findings...|a case study|
|Introduction to the case|
|Research Questions|
• 1 consistent preference? • 2 full ladders A-C-V?• 3 Number of ladders? Number of elements?
|Method|
• 46 preschoolers • Average Age about 5– 2 to 7 years
• Gender: 19 girls and 27 boys • School
|Procedure|
1. Explorative game play x 3(counterbalancing)
2. Preference distinction (ranking)
3. Laddering interview4. Free play option
|Procedure|
• Example preference distinction via ranking
|Results|
1 Consistent preference?
• Yes! Consistent preferences between answers on preference distinction questions & free play option (Likelihood Ratios,, all p<0.01)
|Results|
2 Full ladders A-C-V?• No Values
- 9 (/46): preferences > [stop]- 19 (/46): preferences > attributes > [stop]- 24 (/46): preferences > attributes > conseq. > [stop]
• probing further = more external causesStarting to climb down the ladder again...
|Results|
• Example preferences > attributes > [stop]
|Results|
3 Number of elements - ladders?• Average= 1.72 ladder; 2.81 elements
• Mean age respondents not producing ladders+/- 3.5 years old
• Mean age respondents producing ladders+/- 5 years old
• The older they are, the higher the number of ladders and elements
Significant (all p<0.01) and positive correlations
|Discussion|
• Laddering in HCI– How many elements do you need?– Striving for values per se?– Asking for intentions rather than reflections
• Individual technique– Inviting pairs of children?
• Adult interviewer vs hand puppet?
|Conclusion|
