Categorizing entities by common role

Many categories group together entities that play a common role across situations. For example, guest and host refer to complementary roles in visiting situations and, thus, are role-governed categories (A. B. Markman & Stilwell, Journal of Experiment & Theoretical Artificial Intelligence, 13, 329-358, 2001). However, categorizing an entity by role is one of many possible classification strategies. This article examines factors that promote role-governed categorization over thematic-relation-based categorization (Lin & Murphy, Journal of Experimental Psychology: General, 130, 3-28, 2001). In Experiments 1a and 1b, we demonstrate that the use of novel category labels facilitates role-governed categorization. In Experiments 2a and 2b, we demonstrate that analogical comparison facilitates role-governed categorization. In Experiments 1b and 2b, we show that these facilitatory factors induce a general sensitivity to role information, as opposed to only promoting role-governed categorization on an item-by-item basis.     

The root delusion enshrined in common sense and language

This paper is a critique of certain arguments given by the Milindapanha and Jay Garfield for the conventional nature of reality or existence. These arguments are of interest in their own right. They also are significant if they are presumed to attack an obstacle we all face in achieving non‐attachment, namely, our belief in the inherent or substantial existence of ourselves and the familiar objects of our world. The arguments turn on a distinction between these objects, and some other way of conceiving of them, in terms of which their conventional existence becomes apparent. After the distinction and the arguments that depend on it are shown to be problematic, the paper concludes with some reflections on the doctrine of skillful means and its applicability to Buddhist philosophical argument.     

Childhood aggression and social adjustment as antecedents of delinquency

A sample of 2,453 grade school children were followed into young adulthood through record sources. Teacher interviews provided information about low-peer-status children that was assessed in relation to subsequent delinquency for both sexes and young adult criminality for males. A multivariate design evaluated the joint effects of social class, a measure of family disturbance, and childhood problem behavior factors as antecedents of delinquency. Childhood aggression emerged as the most prominent antecedent factor for males but not for females. Social class and family disturbance were associated with aggression but did not have significant direct effects on delinquency. Aggression was related to severity of delinquency. Dispositional status, reflecting severity, was the best indicator of which delinquent males would have adult criminal records. A causal model is presented.The study was supported by a grant from the Scottish Rite Schizophrenia Research Program, N.M.J., U.S.A. Portions of the study were presented at the Life History Research conference in Monterey, California, 1981. The authors wish to thank June White, Cindy Hanson, and Ned Worell for their help in conducting this research. Data for this research was originally gathered by Merrill Roff. Follow-up data were contributed by Ronald Peek, Donald Bamber, Charles Watson, Shiela Makie, William S. Ward, Edward S. Posey, Chris Hemlabs, and Harriet Barnes.     

Satisfaction and psychological well-being as antecedents of organisational commitment

Satisfaction and psychological well-being as antecedents of organisational commitment. The role of organisational commitment in public administration and its repercussions on the institution are examined in this study. It reports part of a larger research project that studies job satisfaction, life satisfaction, and psychological well-being as antecedents of organisational commitment. Data were collected from 697 public-sector employees, using questionnaires. Results showed that job satisfaction, life satisfaction, and psychological well-being were strong predictors of organisational commitment. Higher levels of job satisfaction, life satisfaction, and psychological well-being were associated with more favourable perceptions of organisational commitment. Furthermore, this study highlights the impact of dynamic work on the employee's commitment.     

Odors are expressible in language,as long as you speak the right language

From Plato to Pinker there has been the common belief that the experience of a smell is impossible to put into words. Decades of studies have confirmed this observation. But the studies to date have focused on participants from urbanized Western societies. Cross-cultural research suggests that there may be other cultures where odors play a larger role. The Jahai of the Malay Peninsula are one such group. We tested whether Jahai speakers could name smells as easily as colors in comparison to a matched English group. Using a free naming task we show on three different measures that Jahai speakers find it as easy to name odors as colors, whereas English speakers struggle with odor naming. Our findings show that the long-held assumption that people are bad at naming smells is not universally true. Odors are expressible in language, as long as you speak the right language.     

Nonimmediate language style and inconsistency between private and expressed evaluations

It was hypothesized that certain language style variations would reflect apprehension about affirming the validity of communication content. Wiener and Mehrabian (Language within language: Immediacy, a channel in verbal communication. New York: Appleton-Century-Crofts,1968) have identified a cluster of such variations called verbal nonimmediacy, which they describe as indicators of psychological distance between the communicator and his/her communication. Four experiments are reported. Experiments 1 and 2 showed that communication about positive manifestations of disliked traits and negative manifestations of liked traits was more nonimmediate than when positive manifestations of liked traits or negative manifestations of disliked traits were described. This was true both when one's own or another's personality traits were described. In Experiment 3, nonimmediacy was found to increase when communications involved clear fabrications about either one's liked or disliked traits. Experiment 4 showed that when self-regard was experimentally manipulated, low self-regard subjects showed more opinion conformity and nonimmediacy in their disclosures to a confederate than did high self-regard subjects.     

Situational and dispositional factors as antecedents of ingratiatory behaviors in organizational settings

This study examined both situational and dispositional antecedents of four ingratiatory behaviors: other-enhancing, opinion conformity, favor rendering, and self-promotion. The two situational variables (i.e., role ambiguity and leader-member exchange) and the four dispositional variables (i.e., self-esteem, need for power, job involvement, and shyness) were considered as antecedents to each of the ingratiatory behaviors. Results from a sample of 136 full-time employees suggested that each of the ingratiatory behaviors had a unique set of antecedents and that the dispositional variables explained significant additional variance beyond the variance explained by the situational variables.     

Extraversion and Neuroticism as antecedents of emotion regulation and dysregulation in adulthood

This longitudinal study examined the role of Extraversion and Neuroticism as antecedents of emotion regulation and dysregulation among 89 women and 81 men. When participants were 27 years old, their Extraversion and Neuroticism were assessed with the standardized version of the Eysenck Personality Questionnaire. At age 33, they completed the Big‐Five Personality Inventory, an authorized adaptation of the NEO Personality Inventory. Emotion regulation, operationalized as an active attempt to turn a negative emotion toward a more positive direction, and measured by the Repair subscale of the Meta‐Regulation Scale, and emotional social support, as measured by the Life Situation Questionnaire, were assessed when participants reached 36 years of age. Emotional ambivalence, a type of emotion dysregulation, was also assessed in this wave. Structural equation modelling demonstrated that prior Neuroticism led to higher emotional ambivalence and lowered use of Repair at age 36. Prior Extraversion, on the other hand, was linked to lower emotional ambivalence at age 36. Extraversion also led to higher attempts to rely on emotional social support to regulate emotions, but less interest in using Repair. Correlational findings revealed that Extraversion and Neuroticism showed differential continuity between ages 27 and 33. Copyright © 2001 John Wiley & Sons, Ltd.     

Speech and non-speech processing in people with specific language impairment: a behavioural and electrophysiological study

McArthur and Bishop (2004) found that people with specific language impairment (SLI) up to 14 years of age have poor behavioural frequency discrimination (FD) thresholds for 25-ms pure tones, while people with SLI upto 20 years of age have abnormal auditory N1--P2--N2 event-related potential (ERP) responses to the same tones. In the present study, we extended these findings to more complex non-speech and speech sounds by comparing younger (around 13 years) and older (around 17 years) teenagers with SLI and controls for their behavioural FD thresholds and N1-P2 ERPs to 25 and 250-ms pure tones, vowels, and non-harmonic complex tones. We found that a subgroup of people with SLI had abnormal responses to tones and vowels at the level of behaviour and the brain, and that poor processing was associated with the spectral complexity of auditory stimuli rather than their phonetic significance. We suggest that both the age of listeners and the sensitivity of psychoacoustic tasks to age-related changes in auditory skills may be crucial factors in studies of sound processing in SLI.     

Mind the gap: the lack of common language in healthcare ethics

Ethics consultation services provide support to staff, patients, and family members who find themselves in morally difficult situations in healthcare settings. Not unlike other clinical consultation services, ethics consultation activities should be well documented. Good documentation allows for evaluation of the consultation process and the ability to refer back to consults when needed, and provides data for future research in healthcare ethics (HCE). In our exploration of existing HCE documentation systems, we identified two main points of interest. First, HCE information documentation systems are powerful tools for providing information on ethics consultation services.These documentation systems can be used to produce detailed reports on various HCE activities both institutionally and cross-institutionally. Second, our findings indicate greater agreement in the language and terminology of HCE needs to be established. Cultivation of such common language is needed in order to develop a standard healthcare ethicists can use to document and categorize consults. Standardization of language would allow data to be readily comparable and lead to more consistency in documentation of ethics consultations. Ultimately, standardization of documentation can also constitute a standard of practice for HCE in general.The development of such standards is essential for any developing profession, and will be required for HCE as it moves in towards professionalization in Canada.     

The Big Five personality traits as antecedents of eco-friendly tourist behavior

This article reports the findings of a study, conducted among 227 foreign tourists who visited Cyprus, that aimed to identify the relationships between the Big Five personality dimensions and tourists’ environmentalism. Structural equation modeling revealed that Agreeableness, Conscientiousness, Extraversion, and Neuroticism are positively associated with pro-environmental tourist behavior. In contrast, no significant relationship was observed between Openness and ecological action.     

Constructions as categories of language

What causes children to categorize distinct utterances they hear into a constructional generalization? That is, what makes subjects create a constructional category instead of treating each utterance as a distinct unrelated idiom? One simple factor that encourages the learning of abstract categories is shared concrete similarity. When instances share concrete attributes, learners are more likely to categorize them together, and moreover are more likely to attend to their abstract commonalities [Gentner, D., & Medina, J. (1998). Similarity and the development rules. Cognition, 66, 236-297; Markman, A.B., & Gentner D. (1993). Splitting the difference: A structural alignment view of similarity. Journal of Memory and Language, 32, 517-535]. This paper reports results that confirm the prediction that presentation of items with concrete shared similarity early in training enhances language learning in adults.     

Competence in everyday activities as a predictor of cognitive risk and mortality

This study examined the association of a performance-based measure of everyday functioning with clinically meaningful outcomes. Elderly participants in a prospective study of dementia were assessed at two occasions on the Everyday Problems Test for Cognitively Challenged Elderly (EPCCE), a performance-based measure of everyday functioning. Older adults who remained cognitively intact performed approximately 0.66 SD units higher on the EPCCE at both occasions than elders rated as impaired, when covarying on age, education, gender, and cognitive status. Relative to the nonimpaired participants, decline in EPCCE performance over a 2-year interval was significantly greater for impaired participants and those participants who transitioned from nonimpaired to impaired over the course of the study. Increased risk of mortality was associated with lower baseline scores and decline in EPCCE performance even after controlling for demographic variables and performance on the Mini-Mental State Examination. Given the clinical importance of identifying "at risk" elders for impairment, the findings from this study provide initial evidence for the predictive utility of performance-based measures of everyday functioning.
