Bigrams and the richness of the stimulus

Recent challenges to Chomsky's poverty of the stimulus thesis for language acquisition suggest that children's primary data may carry "indirect evidence" about linguistic constructions despite containing no instances of them. Indirect evidence is claimed to suffice for grammar acquisition, without need for innate knowledge. This article reports experiments based on those of Reali and Christiansen (2005) , who demonstrated that a simple bigram language model can induce the correct form of auxiliary inversion in certain complex questions. This article investigates the nature of the indirect evidence that supports this learning, and assesses how reliably it is available. Results confirm the original finding for one specific sentence type but show that the model's success is highly circumscribed. It performs poorly on inversion in related constructions in English and Dutch. Because other, more powerful statistical models have so far been shown to succeed only on the same limited subset of cases as the bigram model, it remains to be seen whether stimulus richness can be substantiated more generally.     

The diagnosis and cure of garden paths

We propose that, for the human parser, recovery from garden paths consists in repairing the structure built so far, rather than reparsing the input. The difficulty of a repair is attributable not to the cost of effecting the structural alterations but to the cost of deducing which alterations are needed. The parser must diagnose its error in order to correct it. The error is signaled by an input word that is incompatible with the current structure; this is the symptom from which the diagnosis must be made. If the error is transparently clear from the nature of the symptom, recovery is easy; but sometimes the necessary reasoning is obscure, and then the diagnosis is unsuccessful and the garden path persists. Unlike other repair models, the diagnosis model needs no special mechanism for revising garden path analyses. The garden path recovery device is the same machine as the first-pass parser, merely set into emergency mode. When faced with a breakdown the parser does not stop its normal activities and enter a new mode of reasoning to detect what went wrong. It simply continues to parse, attaching the problematic input item in the least ungrammatical way it can, despite the conflict with previously built structure. This conflict is productive; it provokes adjustments to the existing structure. In successful cases, one adjustment leads to another until a stable state is reached, at which point the original error will have been eliminated. Examples suggest that the parser gives more weight to syntatctic than to pragmatic acceptability; only a syntactic clash between the input and the existing structure sets the adjustment process in motion.     

Recent and emerging trends in marital and family therapy regulation

The number of states in the United States that formally credential marital and family therapists has tripled to 31 during the last decade. This paper reviews and compares the basic licensure and certification requirements in these states, and explores a number of broad issues currently confronting the field of marital and family therapy regulation. Several recommendations for improving the quality of MFT regulation are also provided.president of the Association of Marital and Family Therapy Regulatory Boards.     

Concepts: a potboiler

An informal, but revisionist, discussion of the role that the concept of a concept plays in recent theories of the cognitive mind. It is argued that the practically universal assumption that concepts are (at least partially) individuated by their roles in inferences is probably mistaken. A revival of conceptual atomism appears to be the indicated alternative.     

Adolescent attitudes toward body image and anorexic behavior

This study explored the relationship between anorexic behavior and selected dimensions of body image. Anorexic behavior was assessed by two scales, the Eating Attitudes Test (EAT 26) (Garner, Olmstead, Bohr, & Garfinkel, 1982) and the Eating Disorders Inventory (EDI) (Garner, Olmstead, & Polivy, 1983). Predictor variables, selected dimensions of body image, physical attractiveness, self-esteem, and physical effectiveness, were measured by scales adapted by Lerner and Karabenick (1974) and Lerner, Orlos, and Knapp (1976). Multiple regression techniques were used to determine how much of the tendency toward anorexic behavior can be predicted by selected dimensions of body image. The major focus of the analysis was to explore the contributions of each of the dimensions of body image to predicting tendencies toward anorexic behavior in adolescents. The research sample consisted of 169 high school students, aged 15 to 18, who were enrolled in health, physical education, or psychology classes in the spring of 1983. Results indicated that the dimension of self-esteem was the major factor in the prediction of anorexic behaviors as measured by the Eating Disorders Inventory.     

The sausage machine: A new two-stage parsing model

It is proposed that the human sentence parsing device assigns phrase structure to word strings in two steps. The first stage parser assigns lexical and phrasal nodes to substrings of roughly six words. The second stage parser then adds higher nodes to link these phrasal packages together into a complete phrase marker.This model of the parser is compared with ATN models, and with the two-stage models of Kimball (1973) and Fodor, Bever and Garrett (1974). Our assumption that the units which are shunted from the first stage to the second stage are defined by their length, rather than by their syntactic type, explains the effects of constituent length on perceptual complexity in center embedded sentences and in sentences of the kind that fall under Kimball's principle of Right Association. The particular division of labor between the two parsing units allows us to explain, without appeal to any ad hoc parsing strategies, why the parser makes certain ‘shortsighted’ errors even though, in general, it is able to make intelligent use of all the information that is available to it.     

The use of the Core Conflictual Relationship Theme method in describing and comparing gestalt and rational emotive behavior therapy with adolescents

The Core Conflitual Relationship Theme (CCRT) method (Luborsky, 1977) is used to study recurrent relationship patterns in therapy and may be employed as a measure of transference as well. We found only one article in the literature in which it was applied to a mode of psychotherapy, other than psychodynamic (Turner, 1992). In addition, there are only a few articles in the literature that refer to the CCRT method with children and adolescents. In this paper, we applied the CCRT method to two videotaped individual sessions of young adolescent boys, one in gestalt therapy and the other in rational emotive behavior therapy. Results showed that both boys revealed similar core relational theme profiles, but that their respective therapists each dealt differently with these relationship conflicts. In this pilot use of the CCRT with adolescent therapy, we were able to describe relationship patterns and delineate key differences between the two treatment modalities.Stacey Agin, a gradduate student in School Psychology at New York University, submitted this paper for partial fulfillment of the requirements for the Doctorate of Psychology.
