A child with developmental dyslexia or an adult with a reading disorder following brain damage might read the word shoe as 'show', why does this happen? Most current information processing models of reading distinguish between two alternative procedures for the pronunciation of a printed word. The difference between these concerns the level at which orthography is translated to phonology in one, the word-level procedure, a word is read aloud with reference to knowledge specific to that whole word. In the other, the sub-word-level procedure, a printed word is pronounced with reference to knowledge about smaller segments which occur in many different words. Both procedures contribute to normal skilled reading and its acquisition. But if one of the procedures is disrupted, then oral reading will be forced to rely on the alternative routine. Surface dyslexia is a general label for any disorder of reading which results from inadequate functioning of the word-level procedure and in consequence abnormal reliance on sub-word level translation from orthography to phonology. Originally published in 1985, this book provides new evidence about the diverse manifestations of surface dyslexia in adult neurological patients and in children with developmental disorders of reading. The data are drawn from speakers of a range of languages with distinct orthographies. Process models for the pronunciation of print are elaborated, and an appendix gives neurological information on the patients reported.

P. Marler* and H. S. Terrace** *The Rockefeller University Field Research Center Millbrook, NY 12545 **Dept. of Psychology, Columbia University New York, NY 10027, USA For the first half of this century, theories of animal conditioning were regarded as the most promising approach to the study of learning - both animal and human. For a variety of reasons, disillusionment with this point of view has become widespread during recent years. One prominent source of disenchantment with conditioning theory is a large body of ethological observations of both learned and unlearned natural behavior. These challenge the generality of principles of animal learning as derived from the intensive study of a few species in specialized laboratory situations. From another direction, the complexities of human language acquisition, surely the most impressive of learned achievements, have prompted developmental psychologists to doubt the relevance of principles of animal learning. Even within the realm of traditional studies of animal learning, it has become apparent that no single set of currently available principles can cope with the myriad of new empirical findings. These are emerging at an accelerating rate from studies of such phenomena as selective attention and learning, conditioned food aversion, complex problem solving behavior, and the nature of reinforcement. Not very surprisingly, as a reaction against the long-held but essentially unrealized promise of general theories of learning, many psychologists have asked an obvious question: does learning theory have a future? 2 r.

The area of concern to Dr. Wietske Noordman~Vonk has been variously seen as an aspect of long-term memory [F. I], secondary memory [F. 2], memory without record [F. 3], and semantic memory [F. 4J, the latter term being the one pre ferred by Dr. Noordman-Vonk herself. This proliferation of terminology is not an entirely trivial matter, for although the expressions clearly overlap in range, they do draw attention to different features of the phenomena under consideration. The work reported here is concerned with the form of representation and manipulation of our knowledge that, for example, a dog is an animal, or that mothers and daughters are parents and children. To put it more generally, the experiments attempt to elucidate the psychological processes involved in the~emantics of class-inclusion and, most importantly, to extend the explanatory principles there invoked to a new domain, that of kinship relations. Clearly, the connections between "ant" and "insect", or "flower" and "plant" have been known to us - as adults - for some considerable period of time; in the absence of brain injury or degeneration we are unlikely to "forget" that fathers and sons are kin of the same sex. We may therefor- pretheoretically - distinguish between retrieval of such knowledge and. re trieval of a rapidly fading sequence of random numbers that we are asked to recall after a single presentation. It is in this sense that the current work is concerned with long-term and not short-term memory.
