Personality Changes in the Old–Old: A Longitudinal Study

Although many studies have examined the issue of personality stability in early and middle adulthood, few have explored the limits of personality stability in the very old, who are often confronted with major changes in their health and life circumstances which can severely impact adaptive behavior. We conducted a longitudinal study of 74 elderly women with a mean age of 80. They were assessed on the personality traits of Neuroticism, Extroversion, and Openness. Although multiple regression analyses revealed moderate stability on all 3 traits, their stability was found to be influenced by negative changes in life circumstances. For example, decreased social support and increased unmet needs were associated with more Neuroticism. Less Extroversion was associated with poorer health and greater psychosocial needs. The trait of Openness was very stable and was the least affected by life events. These contradictory findings are reconciled by considering personality development within an interaction framework.     

Regret for What not Has Been. Education, and from now You're on Your Own

When children gradually leave theirparental home and the educational task of theirparents is nearly finished, the relationshipbetween them changes. The nature of the closerelationship comes under pressure, and thequestion is whether what is awaited for willnot be hollow. To think about the character andorigin of this emptiness, leads to a reflectionof the essence of the educational relationshipitself. This article discusses the way in which``leaving home'' puts the relationship betweenand the identities of parent and child atstake. It furthermore describes the kind ofregret both partners experience, and arguesthat education is incomprehensible in the end.Coming to understand this has an important andpositive other side: it demands our attentionfor the unforeseen and explains through thisperhaps also partly its attractiveness.     

Mental activation of supportive ties, hostility, and cardiovascular reactivity to laboratory stress in young men and women.

In addition to actual social interactions, internal representations of supportive ties could affect mechanisms linking relationships and health. Undergraduates (41 men, 41 women) wrote about supportive ties or casual acquaintances. Supportive ties were rated as warmer and less controlling than acquaintances, and writing about them evoked reductions in negative affect, especially for low-hostile participants. Compared with the acquaintance condition, the supportive tie condition resulted in reduced heart rate and blood pressure response during a subsequent speech stressor. Among women, the supportive tie condition reduced blood pressure response among low- but not among high-hostile participants. Hence, mental activation of supportive ties altered effects of laboratory stress and might be relevant to the effects of social relations on health.     

Assessment Center Graduate Selection: Decision Processes,Validity, and Evaluation by Candidates

In this contribution, results are presented of research on the predictive validity of a procedure for the career-oriented selection of graduates in The Netherlands. After selection on account of applicant letter, the selection procedure consists of four selective steps: interview with a ‘recruitment officer’, mental test, interview with line manager, and an assessment center comprising two situational exercises. Performance indicators investigated are present salary, average annual changes in function, appraisal of performance, appraisal of management potential, and average annual salary progression. We report on the relationships between the predictors, between the criteria, and between predictors and criteria. The assessment center, together with other steps from the selection procedure, appear to be valid for a number of performance indicators. The correlation between the overall assessment center rating and present salary, corrected for restriction in range, equals 0.55. Stepwise regression indicates that elements from all procedure steps contribute to the prediction of the criterion of average annual salary progression. The disturbing influence of possible ‘crown prince’ -effects on these results, are discussed. Also, the decision process taking place during the end meeting of the assessors is investigated. Finally, the evaluation of the procedure, both by accepted and by rejected candidates, is discussed. These and other results are compared to what is generally known about assessment centers.     

On the factor score controversy

A summary and interpretation of the recent literature on the indeterminacy of factor scores is given in simple terms. A good index of factor score determinacy is the squared multiple correlation of the factor with the observed variables.     

Models,computers and policies: Fifty years of Psychometrika

Mathematical models have been represented inPsychometrika first in biophysics, then in stochastic models of behavior, and later in computer simulations of behavior. Other specialized journals now attract many articles in these areas, butPsychometrika's policy of broad interest in all aspects of quantitative psychology remains sound. This paper reviewsPsychometrika's coverage of mathematical models and computation, and discusses some matters of editorial policy.     

Feeling rules: Testing a model of appraisal—affect relations

The aim of this study was to test a model specifying the relations between appraisals and affects. A theory of the appraisal—affect relation is proposed in terms of general feeling rules differentiating between affects. A taxonomy of ten appraisals is presented, each defined by a specific profile of scores on four appraisal variables: desirability, controllability, responsibility, and the kind of value being at stake in an event. The appraisals are related to nine affect dimensions, resulting from earlier taxonomic research on the structure of affect (Hoekstra, 1986). All predictions following from the theory were tested in two independent samples by structural analysis. The model showed a good fit in both data sets.     

The phenomenology of protest atmosphere: A demonstrator perspective

This paper aims to improve our understanding of demonstrators' atmosphere perceptions, that is, demonstrators' affective state, which is induced by the protest environment. We examined how demonstrators perceive protest atmosphere, why they do so, and whether atmosphere perceptions influence demonstrators' future collective action preparedness. We hypothesized that demonstrators' atmosphere perceptions diverge on a dimension of pleasure, and relate to their grievance (i.e., perceived societal intolerance), group identification, empowerment, and perceived police aggression. A pleasant atmosphere perception was expected to stimulate a demonstrator's future action preparedness. We tested these hypotheses with a mixed‐methods dataset of two Dutch protests, staged by Lesbians, Gays, Bisexuals, and Transgenders and anti‐monarchists. Our analyses revealed that demonstrators' atmosphere perceptions diverge on a dimension of pleasure, and relate to group identification, empowerment, and, for anti‐monarchists, perceived societal intolerance. A pleasant atmosphere perception deters a demonstrator's future action preparedness and also stimulates his or her group identification and empowerment, which, then, stimulate his or her action preparedness.

Why your "head is in the clouds" during thinking: the relationship between cognition and upper space

Higher-order cognition in humans has not generally been viewed as closely entwined with the brain mechanisms mediating more basic perceptual-motor interactions in 3-D space. However, recent findings suggest that perceptual and oculomotor mechanisms that are biased toward the upper field (which disproportionately represents radially distant space) are activated during complex mental operations, ranging from semantic processing to mental arithmetic and memory search. The particularly close affinity with upward conjugate eye deviations--further confirmed in a study of 24 schoolchildren who responded to various mental questions and demands--suggests that active, abstract thinking in humans may have expropriated the focal-extrapersonal brain systems involved in saccadic exploration of the distant environment in other primates.
