RESOLUTION OF LEXICAL AMBIGUITY BY EMOTIONAL STATE

Abstract— The role of emotion in the resolution of lexical ambiguity was investigated. Happy and sad subjects listened to a list of words that included homophones that had happy and neutral meanings (eg., presents-presence ) and homophones that had sad and neutral meanings (eg., mourning-morning ). Words were presented every 3 s, and subjects wrote down the words, as they heard them (Meaning could be identified by spelling in all cases). An interaction between emotional state and homophone category was observed. Sad subjects were more likely to write down sad meanings than were happy subjects. Results are discussed with reference to the literatures on both emotion and lexical access.     

Auditory temporal perception deficits in the reading-impaired: A critical review of the evidence

We assess evidence and arguments brought forward by Tallal (e.g., 1980) and by the target paper (Farmer & Klein, 1995) for a general deficit in auditory temporal perception as the source of phonological deficits in impaired readers. We argue that (1) errors in temporal order judgment of both syllables and tones reflect difficulty in identifying similar (and so readily confusable) stimuli rapidly, not in judging their temporal order; (2) difficulty in identifying similar syllables or tones rapidly stem from independent deficits in speech and nonspeech discriminative capacity, not from a general deficit in rate of auditory perception; and (3) the results of dichotic experiments and studies of aphasics purporting to demonstrate left-hemisphere specialization for nonspeech auditory temporal perception are inconclusive. The paper supports its arguments with data from a recent control study. We conclude that, on the available evidence, the phonological deficit of impaired readers cannot be traced to any co-occurring nonspeech deficits so far observed and is phonetic in origin, but that its full nature, origin, and extent remain to be determined.     

Brief report: Effects of informational feedback on aluminum can recycling

The impact of informational feedback on the depositing of aluminum cans in recycling receptacles at a medium-sized university was investigated. Informational signs were placed over 20-recycling receptacles in three academic buildings. Each informational sign was placed at eye level, with the number of aluminum cans deposited for recycling during the previous week displayed in red digits. A 65% increase in the number of aluminum cans deposited in recycling receptacles with the informational signs was observed. Furthermore, removal of the informational signs was observed to reliably decrease the number of aluminum cans deposited. These results are discussed in the context of employing feedback to increase environmental protection behaviors.     

The detection and management of mental health disorders in pediatric primary care

We reviewed the literature on the detection and management of mental health disorders within the context of pediatric primary care. Pediatricians have displayed a low sensitivity and high specificity in research investigating the detection of mental health impairment in children. Active management efforts characterize approaches to identified cases with more recently trained primary care pediatricians displaying a wider range of skills in managing mental health disorders. Few efforts have been made by pediatric psychologists to develop strategies for enhancing detection rates and management or to empirically evaluate the integration of pediatric psychology services into the primary care context. A conceptual model of factors influencing detection rates and ongoing management of mental health disorders within pediatric primary care is presented. Recommendations are made for more direct involvement of pediatric psychologists within the primary care context.     

Non-heart-beating organ donation: a reply to Campbell and Weber.

In the preceding commentary, Campbell and Weber raise two valid and important issues concerning non-heart-beating organ donation (NHBOD). First, because the procedure links withdrawal of life support and the potential for subsequent organ donation, the desire for organs may create a situation in which care of the dying individual has relatively less importance and the dying may receive suboptimal care. Second, even if concerns about care of the dying were dealt with adequately, there will not be enough non-heart-beating donors to significantly decrease the organ shortage that exists, making the procedure not worth the risk. We agree that attention to the important details of caring for the dying are, and must be, the primary concern of all health care workers caring for those individuals. Ensuring the patients' comfort, dignity, and autonomy, and providing for family and social support are the mainstays of this care. All policies for NHBOD should clearly support and mandate these concepts. Regarding the second concern, we agree that NHBOD is currently rare; however, evidence is increasing that this type of donation has great potential. Continued growth of the practice in this country will depend largely on public acceptance, which we believe will be directly influenced by whether the public perceives that care of the dying is not compromised by this procedure.
