Cultural Variations in Socio-Cognitive Processes

（ Markus & Kitayama, Psychological Review, 1991 ）

In East Asia, people tend to conceptualize “the self” as a relational and contextual existence＝ Interdependent View of Self

In North America, people tend to conceptualize “the self” as an entity detached from others and its context.＝ Independent View of Self

Self Concepts

Analytic Thought

•Origin: Greek Philosophy•The dominant patterns are observed in Euro-Americansocieties

Determinants ：Relatively mild climates; economy does not require strong social ties; nature can be easily controlled.

World View: Things exist by themselvesand can be defined by their attributes(context independent, object-oriented).

Holistic Thought•Origin: East Asian Philosophy(Taoism, Buddhism, East Asian Animism)•The dominant patterns are observable in China,Japan, Korean cultures.

Determinants:Frequently changing climate; Economy requires strong social ties.

World view: Things are inter-related. Various factors are involved in an event (context dependent, context-sensitive).

Socio-Cognitive ProcessesSelf Concept

Causal AttributionAttitude Inference

Attention

The assumption of Cultural Psychology (1): Culture as a worldview shapes human socio-cognitive processes.

Biological Factors

The advanced assumption of Cultural Psychology (2): Culture as a worldview shapes even basic psychological processes, especially attention.

General Assumption in Psychology: Cultural factors are superficial or simply treated as noise.

Results of The Picture-Taking Task

Culture and Attention ：The Rod & Frame Task

Measuring the contextdependency-The RFT(Witkin & Berry, 1977)

(Ji, Peng, & Nisbett, Journal of Personality and Social Psychology, 2000)

Task: Making the rod vertical while ignoringthe angle of the frame.

(Ji, Peng, & Nisbett, Journal of Personality and Social Psychology, 2000)

East Asians were sensitive to the contextual information (Frame). As a result, they made errors when the frame was angled.

For North Americans: They focused on the rod by itself. As a result, they made fewer errors when the frame was angled.

Culture and Attention ：The Frame-Line Task

（ Kitayama, Duffy, Kawamura, & Lersen, Psychological Science, 2003 ）

Absolute Task

Relative Task

East Asians performed the relative task better than the absolute task. North Americans performed the absolute task better than the relative task.
