Helping when the desire is low: Expectancy as a booster

Motivation and Emotion - One might assume that the desire to help (here described as Want) is the essential driver of helping declarations and/or behaviors. However, even if desire to help (Want)...     

Logic of nondeterministic information

In the paper we define a class of languages for representation o knowledge in those application areas when a complete information about a domain is not available. In the languages we introduce modal operators determined by accessibility relations depending on parameters.     

“When the going gets tough,the tough get going”: Motivation towards closure and effort investment in the performance of cognitive tasks

Previous studies have demonstrated that the need for closure (NFC), which refers to an individual’s aversion toward uncertainty and the desire to quickly reduce it, leads to reluctance to invest effort in judgments and decision making. However, we argue that NFC may lead to either an increase or a decrease in effort depending on the availability of easy vs. difficult means to achieve closure and perceived importance of the task goal. We found that when closure could be achieved via both less and more demanding means, NFC was associated with decreased effort unless the task was perceived as important (Study 1). However, when attaining closure was possible via demanding means only, NFC was associated with increased effort, regardless of the task importance (Study 2). Moreover, NFC was related to choosing a more instrumental strategy for the goal of closure, even if this strategy required effort (Study 3). The results are discussed in the light of cognitive energetics theory.     

Correspondence Results for Relational Proof Systems with Application to the Lambek Calculus

We present a general framework for proof systems for relational theories. We discuss principles of the construction of deduction rules and correspondences reflecting relationships between semantics of relational logics and the rules of the respective proof systems. We illustrate the methods developed in the paper with examples relevant for the Lambek calculus and some of its extensions.     

Social representations of the individual: a post-Communist perspective

Social representations of the individual are examined in three post-Communist Central European nations, i.e. the Czech Republic, Slovakia and Hungary, and in three West European nations, i.e. Scotland, England and France. All six nations share a common European history since the Renaissance and Humanism, based on such values as freedom, agency, individual rights and individual responsibility. Many of these values were rejected by the Communist regimes in which people lived for 40 years. Extreme forms of individualism developed in certain West European nations during the same period. In view of these historical events we have asked the following questions: Do people in the post-Communist countries of Central Europe, after 40 years of totalitarian collectivism, still adhere to the values of the common European heritage? What is the meaning of ‘the individual’ today, in Western democracies and in Central European post-Communist nations? Which issues are important for the well-being of the individual and how do they relate to the political and economic circumstances of those individuals? The results show that the values of the common European heritage in Central Europe have not been destroyed and that factors relating to the well-being of the individual differ between the two parts of Europe. These data are discussed in terms of the political and economic situations in Central and Western Europe, the relationship between language and social representations and the structure of social representations. © 1998 John Wiley & Sons, Ltd.     

Suicidal Ideation of Psychiatrically Hospitalized Adolescents has One-Year Predictive Validity for Suicide Attempts in Girls Only

Clinicians commonly incorporate adolescents’ self-reported suicidal ideation into formulations regarding adolescents’ risk for suicide. Data are limited, however, regarding the extent to which adolescent boys’ and girls’ reports of suicidal ideation have clinically significant predictive validity in terms of subsequent suicidal behavior. This study examined psychiatrically hospitalized adolescent boys’ and girls’ self-reported suicidal ideation as a predictor of suicide attempts during the first year following hospitalization. A total of 354 adolescents (97 boys; 257 girls; ages 13–17 years) hospitalized for acute suicide risk were evaluated at the time of hospitalization as well as 3, 6, and 12 months later. Study measures included the Suicidal Ideation Questionnaire-Junior, Multidimensional Anxiety Scale for Children, Children’s Depression Rating Scale-Revised, Beck Hopelessness Scale, Youth Self-Report, and Personal Experiences Screen Questionnaire. The main study outcome was presence and number of suicide attempt(s) in the year after hospitalization, measured by the Diagnostic Interview Schedule for Children. Results indicated a significant interaction between suicidal ideation, assessed during first week of hospitalization, and gender for the prediction of subsequent suicide attempts. Suicidal ideation was a significant predictor of subsequent suicide attempts for girls, but not boys. Baseline history of multiple suicide attempts was a significant predictor of subsequent suicide attempts across genders. Results support the importance of empirically validating suicide risk assessment strategies separately for adolescent boys and girls. Among adolescent boys who have been hospitalized due to acute suicide risk, low levels of self-reported suicidal ideation may not be indicative of low risk for suicidal behavior following hospitalization.
