Diagnosis and Assessment of Depression and Suicidality Using the NIMH Diagnostic Interview Schedule for Children (DISC-2.3)

The Diagnostic Interview Schedule for Children (DISC-2.3) was studied in a sample of 265 adolescent inpatients to determine type and concurrent validity of depressive symptoms and depressive disorder diagnoses for different DISC-2.3 informants (parent, adolescent, both). The Children's Depression Rating Scale — Revised, Reynolds Adolescent Depression Scale (RADS), Suicide Ideation Questionnaire — Junior, Spectrum of Suicide Behavior Scale, and clinical consensus diagnoses were used to assess concurrent validity. Results indicated that (1) parents, compared to adolescents, reported a higher prevalence of all depressive symptoms with the exception of weight change; (2) DISC-2.3 depressive and suicidality symptoms were related positively to independent validating criteria for all informant conditions, suggesting good concurrent validity; (3) the DISC-2.3 both informant condition correctly identified the most depressive disorders; and (4) the parent, but not the adolescent, DISC-2.3 Informant condition contributed to the prediction of clinical consensus diagnoses of depression after taking into account RADS scores.

Compassion: An east‐west comparison

Compassion is an emotion that occupies a central position in Mahāyāna Buddhist philosophy while it is often a neglected subject in contemporary western philosophy. This essay is a comparison between an Eastern view of compassion based upon Mahāyāna Buddhist perspectives and a western view of the same emotion. Certain principles found in Mahāyāna Buddhist philosophy such as the Bodhisattva Ideal, and suffering (dukkha) to name two, are explored for the information they contain about compassion. An essay by Lawrence Blum is taken as representative of a Western view (but not exclusively) and it is analyzed for its shortcomings in light of the Buddhist view. The conclusion briefly describes the value of understanding an eastern view on compassion as a means of filling the void one finds in western medical ethics discourse which focuses so heavily, and redundantly, upon issues such as patient autonomy and paternalism.     

Cognitive arithmetic: Evidence for right hemispheric mediation in an elementary component stage

Earlier studies involving the lateralization of arithmetic abilities have provided evidence for both right and left hemisphere superiorities. It is argued here that part of this inconsistency could be due to the complexity of the arithmetic computations which have been examined. The present studies examined a subprocess shown to be involved in more complex tasks, such as subtraction. The subprocess is the identification of which of two numbers is greater, and was tested by the flashing of a pair of digits to either the left or right visual field. Errors, reaction-times to make a decision, and examination of hand × visual field interactions all indicated that this subprocess is mediated by the right hemisphere. Correlational analysis was used to identify the operations underlying the observed lateralization of this ability. This analysis indicated that an operation indexed by the spatial order in which the digits were presented was effective in the right hemisphere but not the left hemisphere. Speculations on the nature of these operations were presented.     

An Assessment of the Effectiveness of Two Tactics to Reduce Arousal in Crowded Mass Transit Settings1

Studies of crowding in various settings have shown that individuals are aroused and frequently suffer from ill health. Several studies have shown that it is possible to successfully intervene in residential, shopping, and classroom settings to reduce the negative effects of crowding. The present laboratory experiment assessed the effectiveness of two tactics commonly used by passengers in crowded mass transit settings. Results indicated that the two tactics, reading a newspaper or talking to others, failed to reduce arousal. An explanation for the failure of these tactics is offered.     

Do attention and decision follow perception Comment on Miller

In response to Miller's discussion of global precedence, I argue that (a)although perceptual precedence is not the only explanation for asymmetric interference, in some cases it is the most reasonable one; (b) since global precedence does not entail that local and global information cannot interact in their effects on responses, the finding that they do is not incompatible with global precedence; (c) it is dubious that attention or decision are applied just to the resultant of perception rather than determining it or constituting part of it. However, I share some of Miller's doubts about the unique contribution of asymmetric interference data in deciding the issue of global precedence.     

Łukasiewicz logic and the foundations of measurement

The logic of inexactness, presented in this paper, is a version of the Łukasiewicz logic with predicates valued in [0, ∞). We axiomatize multi-valued models of equality and ordering in this logic guaranteeing their imbeddibility in the real line. Our axioms of equality and ordering, when interpreted as axioms of proximity and dominance, can be applied to the foundations of measurement (especially in the social sciences). In two-valued logic they provide theories of ratio scale measurement. In multivalued logic they enable us to treat formally errors arising in nominal and ordinal measurements.     

Dimensions of metaphor

Two rating studies examined several dimensions of metaphorical sentences. A pool of 260 metaphors was constructed, all in the form “(noun phrase) is/are (noun phrase).” In Study 1 all of the items, and in Study 2, 98 of the items were evaluated on ten scales presumed to be important to the comprehension or interpretation of metaphors: semantic relatedness of the subject and predicate, comprehensibility, imageability, imageability of the subject (topic), imageability of the predicate (vehicle), degree of metaphoricity, metaphor goodness, ease of interpretation, number of alternative interpretations, and felt familiarity of the metaphoric ground. Both experiments revealed the rated dimensions to be highly interrelated, but some analyses allowed evaluation of alternative predictions based on current theoretical approaches to metaphor quality and interpretation. The results indicated consistent but mixed support for the general poisitions under consideration as each appeared to have strong and weak areas of applicability. The interrelationships among the scales are discussed, together with implications of the findings for current theories and future metaphor research.     

Allocation of attention according to informativeness in visual recognition

In visual identification, is visual attention attracted to more informative elements, i.e. to elements which are more critical for identification? This question was investigated by having subjects detect some visual probes while performing a primary task that involved identification. The probes were located in the neighbourhood of highly or poorly informative parts of the identified stimuli. Three experiments that followed this rationale were conducted. In Experiment I, it was found that when subjects searched for a target letter in lines of identical background letters, they detected more dots near the feature that distinguished between the target and the background letters. In Experiment 11, it was found that native Hebrew-speaking subjects detected more lines above a letter that distinguished between two English words. Experiment III showed that the effect was reduced but did not vanish when spatial uncertainty was introduced. On the whole, the data are interpreted as suggesting that more attention may indeed be directed to informative regions, and that this effect cannot be solely attributed to retinal factors.
