Preface There is hardly a field in psychology in which the effects of signal detection theory have not been felt. The authoritative work on the subject, Green's & Swets' Signal Detection Theory and Psycho-physics (New York: Wiley) appearedjn 1966, and is having a profound influence on method and theory in psychology. All this makes things exciting but(More)
Similar changes in the spoken language of schizophrenic patients were demonstrated in two separate studies. Schizophrenic patients used less depth of clausal embedding and fewer reduced relative clauses; they uttered more semantically deviant sentences and were more dysfluent than either manic patients or control subjects. They appeared to demonstrate a(More)
A new and syntactically more complex version of the Token Test was developed to investigate the comprehension of complex syntax in schizophrenia. Results suggested that schizophrenic patients as a group demonstrated an impairment of comprehension proportionate to a reduction in the syntactic complexity of their spoken language, which had been demonstrated(More)
The extent to which auditory, tactile, and visual perceptual representations are similar, particularly when dealing with speech and speech-like stimuli, was investigated. It was found that comparisons between auditory and tactile patterns were easier to perform than were similar comparisons between auditory and visual stimuli. This was true across a variety(More)

Two experiments investigated the effects of feedback on absolute judgements of loudness. In Experiment 1, subjects received aceurate, unreliable, or no feedback. While feedback improved the information transmitted in judgments, it gave lower d' values than no feedback. These results were not compatible with a signal detection model with a noisy sensory(More)

The Premorbid Adjustment Scale (PAS) is a new premorbid scale for use in schizophrenia, developed by the National Institute of Mental Health. Its use in a recent Australian study is described. While total scores clearly discriminated schizophrenic from manic patients, and good test-retest reliability was demonstrated for the schizophrenic patients, the(More)
