Chapter 1 1951 It is a widely shared opinion that the new discipline of psycholinguistics emerged during the 1950s. Nothing could be further from the truth. The purpose of this book is to sketch a history of psycholinguistics, the psychology of language, going back to the end of the eight- eenth century, when empirical research began in earnest. Still, it makes sense to begin where psycholinguistics is generally believed to have started, in the early 1950s and more precisely in 1951. That is, to some extent, familiar ground. We will then time travel, over almost two centuries, from the early Romantic period back to this era. In the book’s last chapter, we will return safely to the 1950s, but now recognizing that those years formed no less, but also no more, than a hinge in an old, well-established, and respectable science. The year 1951 will indeed stand out as a hinge in the history of psycholinguistics, although not by design. It was sheer coincidence that three landmark events were packed in that one year halfway through the twentieth century. The first event was the Interdisciplinary Summer Seminar in Psychology and Linguistics, which was held at Cornell University from June 18 to August 10. It set out to “explore the relationships which might exist between the fields of psychology and linguistics” and to make recommendations for the development of a field of overlap coined “psycholinguis- tics.” It is widely considered to be the birth of modern psycholinguistics. The second event was the publication of George Miller’s Language and communication. This textbook reviewed the state of the art in the psychology of language and communica- tion. Its systematic treatment of the empirical literature covered more than five decades of research, occasionally reaching back into the nineteenth-century French and German roots of the field. The new discipline of psycholinguistics that was about to be launched would actually continue a century-old research tradition in the psychology of language. The third landmark was Karl Lashley’s paper “The problem of serial order in behavior.” This was the first frontal attack on the traditional behaviorist associative-chain theories of serial behavior, such as speech and language. In that paper, Lashley pleaded for a new syntactic approach to the treatment of all skilled hierarchical behavior. This was to become a core issue in the imminent “cognitive revolution.” The Interdisciplinary Summer Seminar in Psychology and Linguistics and its follow-up Cornell 1951 The Summer Seminar would not have happened without John Bissell Carroll (1916–2003) (Fig. 1.1 ). John (or Jack) Carroll grew up in Hartford, Connecticut. When he was 14, he 001-Levelt-Ch1-Levelt-Ch 001.indd1.indd 3 99/24/2012/24/2012 22:05:13:05:13 PPMM 4 1951 (a) (b) Fig. 1.1 (a) John Bissell Carroll. © SLTI. Reproduced here with permission.

At the time, Whorf, a fire insurance agent, was also a graduate student of the great linguist Edward Sapir at Yale, and was spending much time on translating an old Nahuatl text. After the talk, John became Whorf ’s youthful assistant, helping him looking up words in a Spanish Nahuatl dictionary. Whorf greatly inspired the young Carroll over the three years of their cooperation and they continued to keep in touch until Whorf ’s death in 1941. Whorf also introduced Jack to Edward Sapir, who, mostly through his writings, had aroused Carroll’s interest in linguistic typology. But, Sapir convinced Carroll that linguistics would not provide him with a viable career. Something like the psychology of language would offer better opportunities. After his undergraduate studies at Wesleyan University, where he was introduced to Weiss’s behavioristic psychology of language, Carroll became B.F. Skinner’s very first graduate student at the University of Minnesota. It was not a perfect match. Skinner, whose work we will discuss in Chapter 8, taught a course in the psychology of language, but Carroll could not recognize or discuss the linguistics he had become well acquainted with through his early training. Skinner, however, was kind enough to introduce him to George Zipf at Harvard University, who, in turn, kindled Jack’s interest in the study of word frequencies. Skinner also had him work with Louis Thurstone at Chicago on a factor analytic approach to the testing of verbal abilities. At the age of 25 Carroll spent a year at Indiana with J.R. Kantor, the most behaviorist of all psychologists of language (see Chapter 8). There Carroll published a lucid Psychological Review paper which laid out a strictly Skinnerian program for the study of verbal behavior. Only a few years later, then a Harvard professor in the department of education, he accepted an invitation from the Carnegie Corporation to review the state of the art in linguistics and its possible appli- cations. During 1950 he traveled all over the country to interview the leading American linguists. The report he submitted was very well received. 1 It recommended the 1 Carroll ( 1953 ) is an extended, revised version of the report. 001-Levelt-Ch1-Levelt-Ch 001.indd1.indd 4 99/24/2012/24/2012 22:05:13:05:13 PPMM THE INTERDISCIPLINARY SUMMER SEMINAR IN PSYCHOLOGY AND LINGUISTICS 5 development of “language psychology” as an interdisciplinary field. As a man of action, Carroll’s next step was to apply to the Social Science Research Council (SSRC) for the funding of a workshop on that topic. It was to become the Summer Seminar in Psychology and Linguistics at Cornell University. Carroll continued to play a central role on the psy- cholinguistic scene, as will be apparent from Chapters 10–13 and 15. In 1974 he moved to the University of North Carolina, where he became emeritus in 1982. The Cornell seminar was both a mutual teaching and a joint planning exercise among three senior psychologists and three senior linguists. Aside from Carroll himself, the psychologists were Charles Osgood of the University of Illinois and Richard Solomon of Harvard University. Osgood had made a name in the psychology of language with his work on the semantic differential (see Chapters 8 and 15). Solomon had worked on tachistoscopic word recognition.2 The linguists were Fred Agard, a specialist in second- language acquisition at Cornell University; Stanley Newman, a former Sapir student and linguistic anthropologist from the University of New Mexico; and Thomas Sebeok, linguist and a leading scholar in semiotics (the study of signs and symbols) from Indiana University. 3 At the end of eight intensive weeks they had produced a 57-page report clarifying the roles of psychology, linguistics, psycholinguistics, and information theory in analyzing the process of communication. It also discussed some of the core research issues for psy- cholinguistics, including potential applications, and it concluded with a list of practical recommendations. Figure 1.2 represents the report’s diagram of the communication process. We are as much speakers as we are hearers; we are both transmitters and receivers of messages, and we normally alternate in reciprocity between these roles. The diagram depicts five com- ponents in the process and indicates the disciplines that (should) deal with them. Psychology deals with the intentional speaker and the interpretative hearer. This is the domain of perceptions, needs, attitudes, intents, meanings, overt acts, etc. Descriptive linguistics is primarily concerned with the structure and content of messages, irrespective of their antecedents or subsequent effects. And then there is psycholinguistics, neatly assigned with the two tasks of studying the speaker’s encoding and the listener’s decoding behavior. When we speak, how do events at the semantic level, the level of ideas, deter- mine our “selection of articulatory motor skill sequences”? And how, when we listen, do “auditory or visual receptor skill sequences” determine our selection of semantic events? The report appeared two years after Shannon and Weaver’s The mathematical theory of communication , which had deeply impressed students of communication. It had suddenly become possible to quantify the amount of information transmitted between sender and receiver, its redundancy, transmission rate and noise in the channel, and so on. George Miller was quick to thoroughly integrate information theory in his textbook. The report dutifully stressed the importance of information theory, but did not do 2 Together with David Howes, he had just discovered the word frequency effect in visual word recogni- tion, see Chapter 12. 3 There were also two graduate students involved, Don Dulany and Leonard Newmark. 001-Levelt-Ch1-Levelt-Ch 001.indd1.indd 5 99/24/2012/24/2012 22:05:13:05:13 PPMM 6 1951 INTENTIVE BEHAVIOR INTERPRETIVE OF SPEAKER MESSAGE BEHAVIOR OF HEARER (psychology) (linguistics) (psychology) ENCODING BEHAVIOR DECODING BEHAVIOR (psycholinguistics) (psycholinguistics) EFFICIENCY OF COMMUNICATION PROCESS (information theory) Fig. 1.2 The communicative process.

Diagram and text assigned to information theory the task of studying the “efficiency” of the communicative process as a whole and of the encoding and decoding processes in particular, but without specifying much further detail. Although the assignments of linguistics versus psychology/psycholinguistics in Figure 1.2 seem natural enough, the text signals deeper issues. After remarking that “psychological theory has little relevance for descriptive linguistics,” the report adds that “when interest shifts to the explanation of linguistic structure it is necessary to appeal to psycholinguistics and perhaps to general psychological theory” (p. 31). Here the authors are (unknowingly) in the good company of Heymann Steinthal, from a century earlier, who we will soon meet in Chapter 2.
