Rethinking Cognition: On Coulter on Discourse and Mind

This paper responds to, and comments on, Coulter's (1999) critique of discursive psychology with particular reference to how cognition is conceptualised theoretically and analytically. It first identifies a number of basic misreadings of discursive psychological writings, which distort and, at times, reverse its position on the status of cognition. Second, it reviews the main ways in which cognition, mental states, and thoughts have been analytically conceptualised in discursive psychology (respecification of topics from mainstream psychology, studies of the psychological thesaurus in action, and studies of the way psychological issues are managed). Third, it considers two of Coulter's substantive issues: the role of correct usage and the role of conceptual vs. empirical analysis. A series of problems are identified with Coulter's development of both of these issues.     

Using image analysis techniques to analyze figure-copying performance of patients with visuospatial neglect and control groups.

Figure copying is often used to detect visuospatial neglect (VSN) in brain-damaged patients. We describe algorithms that enable the computation of parameters for describing figure-copying performance. The researcher can readily implement these algorithms on a computer using image analysis software, and they provide information on goodness-of-fit, relative to a standard model, as well as on dynamic aspects of subjects' performance in completing figure copies. To demonstrate the clinical utility of these algorithms, preliminary results from a group of right-hemisphere brain-damaged patients, some of whom have VSN, are compared with those for age-matched controls.     

The activation of phonology during silent Chinese word reading.

The role of phonology in silent Chinese compound-character reading was studied in 2 experiments using a semantic relatedness judgment task. There was significant interference from a homophone of a "target" word that was semantically related to an initially presented cue word whether the homophone was orthographically similar to the target or not. This interference was only observed for exact homophones (i.e., those that had the same tone, consonant, and vowel). In addition, the effect was not significantly modulated by target or distractor frequency, nor was it restricted to cases of associative priming. Substantial interference was also found from orthographically similar nonhomophones of the targets. Together these data are best accounted for by a model that allows for parallel access of semantics via 2 routes, 1 directly from orthography to semantics and the other from orthography to phonology to semantics.     

Inference deficits in right brain-damaged patients

The inferential reasoning ability of right hemisphere-damaged (RHD) patients was tested by presenting pairs of sentences which were to be treated as single, integrated units. The two sentences treated together made one interpretation likely (a correct inference); one of the sentences in isolation encouraged a different interpretation (an incorrect inference). The position of the misleading sentence was systematically varied. Results showed that, in contrast to normal controls, RHD patients have more trouble answering inference questions, especially those concerning incorrect inferences, than answering questions about the factual content of the passages. Also, RHD patients made significantly more errors when the misleading information was contained in the first rather than in the second sentence; this finding indicates that these patients have difficulty revising previously acquired knowledge in light of new information. These results suggest the impairment of several components of normal discourse processing subsequent to right hemisphere brain damage.     

Language and reading development in profoundly hearing-impaired children—Intelligence,learning, and communication factors: A review

This review defines educational underachievement and presents information confirming the low reading and even lower language development of profoundly hearing-impaired children. It then discusses the role of intelligence, learning ability, and communication factors in this educational underachievement. Teacher and pupil classroom communication are identified as major factors in the poor educational performance of hearing-impaired children. Some research needs are discussed.     

Good science and good philosophy of science

I argue against the assumption that the influence of non-cognitive values must lead to bad science, opening the way for the thesis that non-cognitive values are compatible with good science. This, in turn, allows us to answer feminist questions, principally, How do gender politics influence science? without (1) having to reject the question a priori because theories of science assume that political values cannot influence good scientific work and (2) having made a case for the influence of gender politics upon a particular bit of scientific work, being put into the ludicrous position of saying that it is bad science after all, even though the relevant community of scientists say it is good. Nevertheless, moral and political neutrality is held to be a norm of good science and a tacit metaphilosophical norm governing good philosophy of science, viz., a good philosophy of science reveals and analyzes the morally and politically neutral production of good science. This metaphilosophical norm insures that the philosophy of science (1) is blind to the influence of non-cognitive values on good science if and when these are present and so (2) acquiesces in the moral or political arrangements supported by the science in question.
