Billboards,bombs and shotgun weddings

It’s a presupposition of a very common way of thinking about context-sensitivity in language that the semantic contribution made by a bit of context-sensitive vocabulary is sensitive only to features of the speaker’s situation at the time of utterance. I argue that this is false, and that we need a theory of context-dependence that allows for content to depend not just on the features of the utterance’s origin, but also on features of its destination. There are cases in which a single utterance semantically conveys different propositions to different members of its audience, which force us to say that what a sentence conveys depends not just on the context in which it is uttered, but also on the context in which it is received.     

Sympathy for the Devil: Evidence That Reminding Whites of Their Mortality Promotes More Favorable Reactions to White Racists

Terror management research has often shown that after reminders of mortality, people show greater investment in and support for groups to which they belong. The question for the present research was whether or not this would extend to Euro American investment in their identification as White. Although it seemed unlikely that White participants would directly exhibit increased identification as Whites, we hypothesized that mortality salience would increase sympathy for other Whites who expressed racial pride or favoritism toward Whites. In support of the hypothesis, a White person expressing pride in his race was viewed by White participants as particularly racist relative to a Black person who does so in Study 1, but was deemed less racist after White participants were reminded of their own mortality in Study 2. Similarly, in Study 3, White participants rated an explicitly racist White employer as less racist when they were reminded beforehand of their own mortality. The results were discussed in terms of implications for affiliation with racist ideologies and terror management defenses.     

Stuttering acquired from subcortical pathologies and its alleviation from thalamic perturbation

Acquired stuttering subsequent to subcortical pathology of mesothalamus was observed in four neurosurgical subjects. The patients suffered from chronic pain, seizures, and somatosensory disorders. They also exhibited unpredictable and uncontrollable speech, spasmodic blocks which were devoid of accessory features, and adaptation effect. Therapeutic mesothalamic stimulation, used as a treatment of last resort to relieve the pain and associated symptoms, also had an ameliorating effect on the stuttering. Spontaneously occurring focal abnormal EEG discharges were anatomically delineated and used as a guide for therapeutic stimulation electrode placement. Attentuation of the abnormal discharges was followed by alleviation of symptoms. This investigation examines the clinical characteristics of stuttering in four neurosurgical patients and suggests an electropathologic basis for their mesothalamic-generated speech dysfluencies. The cooccurrence of pain, seizures, somatosensory disorders, and stuttering, and their concurrent amelioration, suggests that both chronic pain and stuttering may be implicated by similar or related reticular electropathologic generators, couched in overlapping reticular networks extending from the brain stem to the thalamus, and that the acquired stuttering may be recruited as one component of a larger syndrome complex.     

Unbiased estimators of ability parameters,of their variance,and of their parallel-forms reliability

Given known item parameters, unbiased estimators are derived i) for an examinee's ability parameter and for his proportion-correct true score, ii) for the variances of and across examinees in the group tested, and iii) for the parallel-forms reliability of the maximum likelihood estimator .This work was supported in part by contract N00014-80-C-0402, project designation NR 150-453 between the Office of Naval Research and Educational Testing Service.

Statistical bias in maximum likelihood estimators of item parameters

Asymptotic formulas are derived for the bias in the maximum likelihood estimators of the item parameters in the logistic item response model when examinee abilities are known. Numerical results are given for a typical verbal test for college admission.     

Maximum likelihood estimation of item response parameters when some responses are omitted

A theoretical model is given for dealing with omitted responses. Two special cases are investigated.This work was supported in part by contract N00014-80-C-0402, project designation NR 150-453 between the Office of Naval Research and Educational Testing Service.

Some determinants of behavioral contrast in pigeons and rats

In Expt. 1, pigeons trained on a multiple variable interval, extinction schedule, showed a positive contrast effect by comparison with control groups trained with S+ only, provided that the interval between stimulus presentations was short (10 sec), but not when it was long (60 sec). Positive contrast also occurred more readily with an easier discrimination, and its appearance was highly correlated with the temporary appearance of transient contrast effects. Although a longer interval between trials produced an overall increase in rate of responding in subjects trained only with S+, it was suggested that this at best represented a different type of contrast effect. In Expt. 2, rats showed positive contrast to S+ when S− was correlated with a lower frequency of reinforcement, but not when it was correlated with a reduced magnitude of reinforcement. The results were discussed in terms of frustration theory.     

The effect of thalamic stimulation in processing of verbal stimuli in dichotic listening tasks: a case study

In dichotic listening tasks, the (dominant) right ear's superiority in processing verbal stimuli has been attributed to its direct anatomic connection with the left dominant hemisphere. The role played by extralinguistic factors, such as attention and functional tuning of the associated cortical structures, has not been carefully examined. This investigation was undertaken to evaluate the effects of the left thalamic electric stimulation on the processing (recognition and recall) of dichotically presented CVC verbal stimuli in a patient being treated for chronic pain. We report the positive effects of electric stimulation (confirmed by increased subcortical metabolic activity using SPECT, a brain imaging technique) on the processing of dichotically presented verbal stimuli.
