Comparison of teaching methods for the emergence and maintenance of untaught relations in foreign language vocabulary acquisition: A systematic replication

In a replication of Daly and K. Dounavi (2020), the researchers evaluated the effect of foreign tact and bidirectional intraverbal teaching on the emergence of untaught relations. Three university students learned three stimulus sets through three types of teaching: native-foreign intraverbal teaching (vocalizing Spanish words that refer to a Japanese textual stimulus), foreign-native intraverbal teaching (reversed relation of native-foreign condition), and foreign-tact teaching (tacting a picture in Spanish). The researchers used an adapted alternating-treatments design to assess the differential effect of each teaching condition on the emergence of untaught relations in a foreign language and collected data on response maintenance. The results replicated previous findings that native-foreign intraverbal and foreign-tact teachings were more effective than foreign-native intraverbal teaching despite previous reporting that the maintenance outcomes may be a result of carryover effects.
