This change made them face with conflicts with others and within themselves. To study how
teachers deal with those conflicts in local practice, I conducted developmental work research, a
kind of action research based on cultural-historical activity theory. As for they are not familiar
with the new curriculum and working as a team, they need to re-construct their image of teaching
and to re-conceptualize their own professional identity. By analyze these data of communicating
others and themselves, I will discuss teachers’ development in practice.

1097.1 Expectancy confirmation in spite of disconfirming evidence: The case of price increases
due to the introduction of the Euro, Tobias Greitemeyer 1 , Stefan Schulz-Hardt 2 , Eva
Traut-Mattausch 1 , Dieter Frey 1 , 1 Ludwig Maximilians University, Germany; 2 Technical
University Dresden, Germany
In Germany, the introduction of the Euro led to a widely shared belief in increasing prices.
However, official statistics suggest that prices remained almost stable. The present research
investigated whether this gap can be explained by people’s reluctance to revise their expectations.
Participants compared the prices of two menus, one with German Mark prices and one with Euro
prices. In five studies, price trend judgements were biased towards rising prices. Results imply
that expectations can influence judgements even when clear disconfirming evidence is available
that can be compared with an objective standard, thus leaving no room for interpretation.
1097.2 Trust asymmetry: A comparison of three theoretical explanations, Mathew White 1 ,
Richard Eiser 2 , 1 University of Sheffield, UK, 2 Sheffield University, UK
Trust is said to be hard to gain but easy to lose, hence 'trust asymmetry' (Slovic, 1993). However,
the popular negativity bias explanation (i.e. bad news is more powerful than good) does not take
into account the multi-dimensional nature of trust (made up of competence, values and openness)
or that for some of these dimensions positive information may be more important than negative. A
re-analysis of Slovic's (1993) data and two follow up experiments suggests that trust asymmetry
only reliably occurs for the openness dimension and thus trust may be more stable than previously
thought.
1097.3 Failure in self-control of eating behavior, Hiroshi Yamaoka, Kaori Karasawa, Nagoya
University, Japan
This study examined the affects that were experienced before and after the dilemma situation of
eating behavior in which people needed to exert self-control effort. The results showed that people
who were highly motivated to control their eating behavior both anticipated (before the activity)
and experienced (after the activity) long-term negative affects such as “regret” or “self-disgust”
more frequently than people who had low motivation. On the other hand, people who could not
control the eating behavior felt “regret” more frequently than people who did. The relation
between affects and failure in self-control was discussed.
