Distribution of probability assessments for almanac and future event questions

This study examines the distribution and calibration of probability assessments given to general knowledge questions and question concerning future events. Two experiments revealed that: (1) People use certainty responses less frequently in response to questions concerning then-future events than to general knowledge questions even when the then-future event questions are easier than the general knowledge questions. (2) Indonesian students previously thought to have little grasp of probabilistic thinking, are able to give realistic probability assessments for then-future events. Cultural and task influences on our findings are discussed in relation to a procedural model of the processes involved in answering a question. We conclude that, as most applications of decision analysis involve future uncertainty, research in probability assessment should concentrate on questions concerning future events rather than on general knowledge questions.     

STRESS AND PERFORMANCE: EFFECTS OF SUBJECTIVE WORK LOAD AND TIME URGENCY1

Subjective work load, time urgency, and other stress/motivation variables were measured for management personnel taking a demanding problem-solving exam at the end of a two-week training course. Comparing measures of precourse ability and final exam performance, the primary findings were that the corrected performance scores had strong negative linear (not inverted-U) relations with both subjective work load and time urgency. General state anxiety and task involvement did not substantially relate to performance. The results are discussed in terms of the nature of this particular task and the predictions of various stress/performance theories. In problem solving or other tasks requiring novel responses, these data suggest that increases in psychological stresses like subjectively high work load and time urgency uniformly impair performance across the whole range of these variables.     

Diversity of ideas about diversity measurement

Measurement of diversity is important in several sciences but has evolved mainly within ecology. An ecological community with many species is more diverse than one with few but the way the total number of individuals is distributed among the species also influences the degree of diversity or heterogeneity. Although not always explicitly used, it can be shown that diversity is a concept of some importance in psychology, too. In general terms quantification of diversity is related to the apportionment of some quantity into a number of well-defined classes. The dual-concept type of diversity index reflects both the number of classes and the degree of evenness (homogeneity) of the apportionment. The quantity that is distributed has commonly been a population of elements and apportionment homogeneity measures population heterogeneity. The statistical context has dominated the thinking about the measurement of diversity, heterogeneity, and homogeneity. Some well-known indices of diversity and the ideas behind them are discussed. It is concluded that the general geometric representation of homogeneity (similarity) and heterogeneity (dissimilarity) (Junge, 1978; 1991) offers a more general approach to the measurement of diversity.     

Bilaterally recorded multiple-unit activity of the cingulate cortex during head turning conditioning with unilateral medial forebrain bundle stimulation

Cats were conditioned to turn their heads using a tone conditioned stimulus (CS) and medial forebrain bundle stimulation (MFB) unconditioned stimulus (US). The CS+ was delivered to one ear at a time, in random order, followed by the US. A tone of a different frequency was used as a CS-. The cats learned to respond differentially to the CSs showing head movements of greater acceleration to the CS+ than CS- over sessions. Bilateral recordings of cingulate cortex multiple-unit activity showed increased response amplitudes over sessions and larger responses in the hemisphere ipsilateral to the US. Since ipsilateral multiple-unit responses did not differ for the CSs, the asymmetry was probably due to the sensitizing effect of the unilateral US. Although increases in cingulate cortex neural activity coincided with increases in conditioned head movements, larger activation of the cingulate cortex ipsilateral to the US suggests that the neural changes were independent of these movements.     

Student Attitudinal Changes in a Counseling Ethics Course

The purpose of this study was to investigate ethical attitude changes in counselors in training related to specific topics during a 16-week, two-credit counseling ethics course. This study indicated that significant attitudinal changes occurred related to professional ethics and self-awareness, dual relationships, impairment, and multiculturalism.     

Fear questionnaires for simple phobias: Psychometric evaluations for a Norwegian sample

The present study presents psychometric data for four different phobic fear questionnaires in a Norwegian sample of 284 subjects. The questionnaires concerned fear of flying, snakes, spiders and a questionnaire of general phobic complaints. The results showed a high estimate of internal consistency, and a very high test-retest reliability for all questionnaires. A low to moderate degree of intercorrelation between the questionnaires appeared. A clear sex difference emerged in responding to all four questionnaires. In addition, a clinical sample of phobics with fear of flying as the main symptom was compared to the larger sample on a fear of flying scale. The results showed a clear difference in responding between the samples. The present study concludes that the four different fear questionnaires yielded a high degree of reliability, and their use in clinical practice is encouraged.     

THE RELATIONSHIP BETWEEN HR PRACTICES AND FIRM PERFORMANCE: EXAMINING CAUSAL ORDER

Significant research attention has been devoted to examining the relationship between HR practices and firm performance, and research support has assumed HR as the causal variable. Using data from 45 business units (with 62 data points), this study examines how measures of HR practices correlate with past, concurrent, and future operational performance measures. The results indicate that correlations with performance measures at all 3 times are both high and invariant, and that controlling for past or concurrent performance virtually eliminates the correlation of HR practices with future performance. Implications are discussed.     

How is Christ Present to the World?*

Abstract: The issue of how Christ is present to the world covers many themes. Christ is the proper presence of God, made known to the world through the witnessing activity of the church. In this, the Holy Spirit plays an important role. Furthermore, in so far as it is God's intention to be present to the world in this way, we may see a link between the notions of God's presence in Christ, providence and sacramentality.     

Predicting Reaction to a Message of Ministry: An Audience Analysis

This study investigated whether audience characteristics identified as important in the conversion and religious recruitment literature could predict reaction to a Christianity-themed recruitment message. More specific goals involved (a) comparing the impact of potential recruits' dispositional attributes and personal motivations versus their situational availability on the persuasive effect of religious recruitment messages; and (b) rank ordering the audience characteristics examined based on their predictive power. Results indicated that dispositional and motivational considerations were more reliable predictors of receivers' responses to the recruitment message than were situational factors. Specifically, five of the six dispositional and motivational variables (i.e., loneliness, perceived childhood attachment history, meaning and purpose, other-orientation, and problem-solving perspective) were—at least under certain conditions—related to participants' interest in the church. The two variables representing situational availability, free time and membership status, however, were either unrelated to interest in the church or related to participants' reactions, but in the opposite direction of what was expected.
