Given the good discrimination in the blind field, the question arises as to whether it is processed differently than discriminations in the intact field. One way of addressing the question was to present stimuli to the two fields simultaneously and to ask D. B. to make a ‘ same-different’ judgment. Two types of stimuli were used: curved vs. straight triangles, and X vs. O. The tests with triangles were ambiguous, possibly because it was not an easy task even for the intact field. The results for X vs. O were clearer, especially when conditions were optimized by varying the size of the stimuli and their positions in the fields. But the cross-field comparison task was more tiring than a within-field task for the blind field alone. In any event, he showed unmistakable evidence of being able to do the matching task. His ability to perform discrimination within the blind field alone was better than across fields. With stimuli to the blind field alone, depending on the parameters, he might report seeing waves, but with the same parameters for the cross-field matching task, he reported seeing nothing in the blind field but something in the good field, even when he was performing at 99% accuracy. A question arises as to whether he carried out the cross-field test sequentially in each field independently, which might be pursued by the analysis of reaction times in the single vs. double field presentations.Less

Given the good performance for cross-field matching, the question arises as to whether D. B. could perform a matching task for stimuli wholly within the blind field. The task was to respond ‘same’ or ‘different’ for Xs and Os presented simultaneously physically close to each other. It was shown that he could discriminate between the stimuli when these were presented singly. Under the conditions of the task, however, he failed the matching task within the blind field. In order to make sure the task was not inherently too difficult because of the stimulus parameters, the same task was given to the intact field, when he scored 100% accuracy. Given the undemanding character of the task for the intact field, the difference between between-field and within-field results is striking and deserves a follow-up under various stimulus conditions.Less

This book brings to the fore recent advances in econometrics for treatment effect analysis. It aims to put together various economic treatment effect models in a coherent fashion, determine those that can be parameters of interest, and show how these can be identified and estimated under weak assumptions. The emphasis throughout the book is on semi- and non-parametric estimation methods, but traditional parametric approaches are also discussed. This book is ideally suited to researchers and graduate students with a basic knowledge of econometrics.Less

People who develop severe mental illness later in life may have advanced education and successful careers. The goal of returning to work for a highly trained individual has different challenges than for people who are starting entry-level jobs. This chapter includes an illustration of an individual who developed severe mental illness after working successfully as a professor and wanted to return to his career. The employment specialist and the rest of the team provide hope and encouragement for people to achieve their goals. The team makes recommendations about specific steps toward reaching the goal. While respect and dignity should be part of every encounter a client has with the employment specialist and other practitioners, the team needs to recognize and respond to the sense of loss in societal and economic status that many people who have had careers and advanced training experience.Less

This chapter deals with the manufacturing industry for Western products that emerged after the opening of the treaty ports. These goods include brushes, buttons, matches, knitted goods, soaps, and bicycles. Although the modern factories that made these products played significant roles in the early stages of industrialization, they eventually went into decline. The combination of modern technology and traditional skills formed another route to industrialization in modern Japan.Less

Neighbouring images in the two eyes that are sufficiently similar are combined in the nervous system and passed on for processing to higher levels. The problem is to determine what stimulus features are used by the visual system to relate images in one retina with those in a corresponding region of the other retina. For example, binocular stimuli may be treated as one stimulus only if they are similar in contrast, shape, colour, and motion. One can also ask whether image matching is done only locally or both locally and globally over wide areas. This chapter addresses these questions. Topics covered include correlating binocular images, local matching rules, and global matching rules.Less

Analytic procedures suitable for the study of human disease are scattered throughout the statistical and epidemiologic literature. Explanations of their properties are frequently presented in mathematical and theoretical language. This text provides a clear understanding of the statistical methods that are widely used in epidemiologic research without depending on advanced mathematical or statistical theory. By applying these methods to actual data, this book reveals the strengths and weaknesses of each analytic approach. The book combines techniques from the fields of statistics, biostatistics, demography, and epidemiology to present an overview that does not require computational details of the statistical techniques described. Throughout, the text contains illuminating discussions with new elements for this edition, including the analysis of multi-level categorical data and simple, intuitive arguments that exponential survival times cause the hazard function to be constant. There are also new applied examples to illustrate such topics as the pitfalls of proportional mortality data, the analysis of matched pair categorical data, and the age-adjustment of mortality rates based on statistical models. The most important new feature is a chapter on Poisson regression analysis. This essential statistical tool permits the multivariable analysis of rates, probabilities, and counts.Less

This chapter focuses on the differential involvement of multiple areas of the lateral frontal cortex in rule‐based behavior. It presents evidence obtained from physiological and anatomical studies of monkeys and discusses the specific role played by each area from the viewpoint of a hierarchical network within the lateral frontal cortex. It introduces several key types of neuronal activity found in the prefrontal, premotor, and primary motor cortices of macaque monkeys performing a variety of rule‐based behaviors, such as following location‐matching rules or shape‐matching rules.Less

The same principles that apply to the design of experiments also apply to the design of an observational study, but instead of manipulating the animals, the observer controls the way he or she takes observations. The three principles are: independent replication; not confounding variables; and removing known sources of variation by blocking or matching. The chapter shows how these three principles can be applied to the design of observations, and discusses issues that often get in the way of valid designs such as pseudoreplication, experimenter bias, and choice of which animals to observe. Some simple observational designs are introduced.Less

This chapter shows how it is that we can abandon the traditional picture and develop theories like those Chapters 4 and 5 show to be needed. It offers an account of simple sentence intuitions that makes no use of ‘matching propositions’, drawing instead on considerations of psychological processing. The explanation developed fits quite naturally both with widely accepted assumptions about cognitive architecture and with the relevant empirical data. It is also compatible with a wide variety of views on the semantics of names.Less

This chapter provides a short overview on the perceptual abilities of dogs. Vision, audition, and olfaction are described in detail, including the possible experimental methods which could be used for studying such phenomena as colour vision, form recognition, hearing acuity, or olfactory sensitivity. Understanding of perceptual abilities can be important in relating the animal's behaviour to its original (ancestral) environment, but also in designing experiments which rely on the dog's ability to perceive stimuli or events manipulated by the experimenter.Less

This chapter examines the phase error problem and also shows, via a dispersion analysis, that higher order methods can significantly improve phase accuracy. Once a solution is computed it is desirable to assess the accuracy of the solution to determine how to refine the mesh. The next section of the chapter presents a residual based a posteriori error analysis that shows how both the error in the curl of the solution and the divergence needs to be assessed. The final section concerns absorbing boundary conditions, which are often used in preference to the ‘exact’ techniques in Chapters 10-12 to ease the implementation burden. The standard Silver-Muller condition, infinite elements, and the justly popular Perfectly Matched Layer (PML) of Berenger are discussed.Less

This chapter presents some personal thoughts about future possibilities for CDM based upon current involvement as a research consultant and as a social work doctoral faculty member. It briefly describes some practitioner-initiated, multidisciplinary CDM studies, and some CDM doctoral dissertations that are currently in the works. It then discusses prior efforts to create experimental analogs with available data that most closely approximate the RCT research ideal. It introduces a promising new data-analytic tool (Propensity Score Matching) that carries with it exciting data-mining possibilities. Finally, the chapter stakes a final claim for a model of social work research that includes CDM in particular and practitioner-research more generally.Less

This chapter introduces Stevens' direct methods of magnitude estimation, magnitude production, and cross-modality matching. It summarizes Stevens' estimates of exponent values for twenty-four different stimulus continua; the extension of Stevens' ideas to non-metric continua and to inverse attributes; and compatibility studies showing that the different direct methods applied to the same continua yield mutually compatible estimates of the exponents. The chapter ends with three interpretations of these findings that are explored in subsequent chapters: (i) as a purely operational characterization; (ii) as a definitive measure of sensation; and (iii) a belief that the power law transform is realized in elementary neural function.Less
