This is a new release of the original 1949 edition.

This essay has two goals. The first is to define the behavioristic study of natural events and to classify behavior. The second is to stress the importance of the concept of purpose.Given any object, relatively abstracted from its surroundings for study, the behavioristic approach consists in the examination of the output of the object and of the relations of this output to the input. By output is meant any change produced in the surroundings by the object. By input, conversely, is (...) meant any event external to the object that modifies this object in any manner. (shrink)

As this book reveals, his vision was much more complex and interesting. He hoped that machines would release people from relentless and repetitive drudgery in order to achieve more creative pursuits.

This book is a volume in the Penn Press Anniversary Collection. To mark its 125th anniversary in 2015, the University of Pennsylvania Press rereleased more than 1,100 titles from Penn Press's distinguished backlist from 1899-1999 that had fallen out of print. Spanning an entire century, the Anniversary Collection offers peer-reviewed scholarship in a wide range of subject areas.

The intention and the result of a scientific inquiry is to obtain an understanding and a control of some part of the universe. This statement implies a dualistic attitude on the part of scientists. Indeed, science does and should proceed from this dualistic basis. But even though the scientist behaves dualistically, his dualism is operational and does not necessarily imply strict dualistic metaphysics.

Wayfinding is generally understood as the process of purposefully navigating to distant and non-visible destinations. Within this broad framework, uninformed searching entails finding one’s way to a target destination, in an unfamiliar environment, with no knowledge of its location. Although a variety of search strategies have been previously reported, this research was largely conducted in the laboratory or virtual environments using simplistic and often non-realistic situations, raising questions about its ecological validity. In this study, we explored how extant findings on (...) searching translate to a real-world environment, using a phenomenologically informed experiment. Our findings demonstrate a previously undescribed complex and dynamic interplay of different search strategies. Importantly, our results reveal that: (i) the presence of other people is importantly entangled with the process of searching; and (ii) people frequently probe and switch between search strategies based on local environmental characteristics. Together, our results reveal that search behaviour is critically dependent on environmental features and that searching in complex real-world settings should not be conceptualised as depending on a simple singular strategy. This raises questions about the dominance of laboratory-based experiments and their narrow cognitivist framework, highlighting the value of studying wayfinding in the real world. (shrink)

“Articulate models” subservient to formal intelligence are imagined to be heterarchies of automata capable of performing the “symbolic (quasi-spatial) syntheses” of Luria (1973), where “quasi-spatial” points to the abstract core of spatiality: the symbol productions, combinations, and substitutions of algebraic reckoning. The alleged cognitive role of internal “topographic images” and of “efference copies” is confronted with this background and denied.

Assessing the vast arena that continues to grow in pursuit of accountability in American hospitals, this paper raises the following question: Is this enterprise geared toward making hospitals better or toward making them only look better? ‘Accountability’ has become an umbrella concept to signal the need to demonstrate — to others — that performance is being measured and perfected. The author asserts that there is an imperfect fit between health‐care and the industrial model being used to measure quality of care (...) due to four problematic issues: the nature of contemporary patient care, the overstating and overselling of accountability proposals, inflated expectations placed upon ‘rationalization’, and insufficient attention afforded accident and error. The paper concludes with a plea for reconsideration of the tilt toward a business approach to health‐care, asking if, in our zeal to hold hospitals accountable, we are measuring what is important or simply making important what we can measure.

But of course Derrida’s appeal to context and to authorial intention constitutes an abandonment of the deconstructive method. As Christopher Norris has written of de Man, “we read in defiance of his own repeated counsel” if we read his work “by asking what might have been the motives, political or otherwise, that led to his adopting the stance they exhibit.”2Derrida emphasizes repeatedly that de Man’s objectionable acts were committed almost half a century ago, when he was twenty-one and twenty-two years (...) old. That’s an important argument. But the moral problems de man poses do not end in 1942 when he stopped writing for Le Soir; a second and in some ways more serious moral problem recurs throughout his adult-life, during which de Man kept his youthful pro-Nazi and anti-Semitic writings a secret. John Wiener is professor of history at the University of California, Irvine. His articles “Deconstructing de Man” and “Debating de Man” appeared in The Nation. (shrink)

Spoken word recognition involves a perceptual tradeoff between the reliance on the incoming acoustic signal and knowledge about likely sound categories and their co-occurrences as words. This study examined how adult second language (L2) learners navigate between acoustic-based and knowledge-based spoken word recognition when listening to highly variable, multi-talker truncated speech, and whether this perceptual tradeoff changes as L2 listeners gradually become more proficient in their L2 after multiple months of structured classroom learning. First language (L1) Mandarin Chinese listeners and (...) L1 English-L2 Mandarin adult listeners took part in a gating experiment. The L2 listeners were tested twice—once at the start of their intermediate/advanced L2 language class and again two months later. L1 listeners were only tested once. Participants were asked to identify syllable-tone words that varied in syllable token frequency (high/low according to a spoken word corpus) and syllable-conditioned tonal probability (most probable/least probable in speech given the syllable). The stimuli were recorded by 16 different talkers and presented at eight gates ranging from onset-only (gate 1) through onset+40 ms increments (gates 2 through 7) to the full word (gate 8). Mixed-effects regression modeling was used to compare performance to our previous study which used single-talker stimuli (Wiener, Lee, & Tao, 2019). The results indicated that multi-talker speech caused both L1 and L2 listeners to rely greater on knowledge-based processing of tone. L1 listeners were able to draw on distributional knowledge of syllable-tone probabilities in early gates and switch to predominantly acoustic-based processing when more of the signal was available. In contrast, L2 listeners, with their limited experience with talker range normalization, were less able to effectively transition from probability-based to acoustic-based processing. Moreover, for the L2 listeners, the reliance on such distributional information for spoken word recognition appeared to be conditioned by the nature of the acoustic signal. Single-talker speech did not result in the same pattern of probability-based tone processing, suggesting that knowledge-based processing of L2 speech may only occur under certain acoustic conditions, such as multi-talker speech.

In a recent essay Professor Taylor criticizes the criteria used by Rosenblueth, Wiener and Bigelow in 1943 to distinguish purposeful from non-purposeful behavior. He also criticizes our definition of behavior, our concept of the vague as opposed to the general, our use of the word correlation, and our statement that a system may reach a final condition. Indeed, there seems to be little, if anything, in our paper to which he does not emphatically object.He maintains that the notions of purpose (...) and teleology are not only useless for the understanding of mechanical behavior, but wholly incongruous when applied to this behavior. He further affirms that our use of the term purpose “bears no similarity whatever to the meaning which is ordinarily attached to it.” He does not state, however, his own notions of purpose and teleology; and the meaning which he considers to be ordinarily attached to the term purpose. This omission weakens his criticism considerably. (shrink)
