  We present scientometric results about world-wide centers of excellence in
psychology. Based on Web of Science data, domain-specific excellence can be
identified for cities where highly cited papers are published. Data refer to
all psychology articles published in 2007 which are documented in the Social
Science Citation Index and to their citation frequencies from 2007 to May 2011.
Visualized are 214 cities with an article output of at least 50 in 2007.
Statistical z tests are used for the evaluation of the degree to which an
observed number of top-cited papers (top-10%) for a city differs from the
number expected on the basis of randomness in the selection of papers. Map
visualizing city ratios on significant differences between observed and
expected numbers of highly-cited papers point at excellence centers in cities
at the East and West Coast of the United States as well as in Great Britain,
Germany, the Netherlands, Ireland, Belgium, Sweden, Finland, Australia, and
Taiwan. Furthermore, positive but non-significant differences in favor of high
citation rates are documented for some cities in the United States, Great
Britain, the Netherlands, the Scandinavian and the German-speaking countries,
Belgium, France, Spain, Israel, South Korea, and China. Scientometric results
show convincingly that highly-cited psychological research articles come from
the Anglo-American countries and some of the non-English European countries in
which the number of English-language publications has increased during the last
decades.
