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.     

Electronic mail,a new written‐language register: A study with French‐speaking adolescents

The aim of this study was to determine the extent to which the linguistic forms used by adolescents in electronic mail (e‐mail) differ from those used in standard written language. The study was conducted in French, a language with a deep orthography that has strict, addressee‐dependent rules for using second person personal pronouns (unfamiliar and familiar forms). Data were collected from 80 adolescents ages 12 to 15 in a natural situation where they had to introduce themselves by e‐mail to two addressees (peer/teacher). Participants were divided into two groups (skilled/unskilled in computer‐mediated communication). Their emails contained a large number of orthographic deviations (the most frequent being neographic forms). Participants skilled in computer‐mediated communication (CMC) deviated more than unskilled ones did. The number of orthographic deviations was not linked to the participants' standard writing ability. The personal‐pronoun data clearly showed that adolescents used the familiar form of ‘you’ (tu) to address the peer and the unfamiliar form (vous) to address the teacher. We conclude that, for adolescents, e‐mail constitutes a distinct written‐language register. Nevertheless, the e‐mail register seems to follow the pragmatic rules of standard spoken and written interaction.     

Matters of the variable heart: respiratory sinus arrhythmia response to marital interaction and associations with marital quality

Maintenance of relationship quality requires self-regulation of emotion and social behavior, and women often display greater effort in this regard than do men. Furthermore, such efforts can deplete the limited capacity for self-regulation. In recent models of self-regulation, resting level of respiratory sinus arrhythmia, quantified as high-frequency heart rate variability (HF-HRV), is an indicator of self-regulatory capacity, whereas transient increases in HF-HRV reflect self-regulatory effort. To test these hypotheses in marriage, 114 young couples completed measures of marital quality and a positive, neutral, or negative initial marital task, preceded and followed by resting baseline assessments of HF-HRV. Couples then discussed a current marital disagreement. Resting HF-HRV was correlated with marital quality, suggesting that capacity for self-regulation is associated with adaptive functioning in close relationships. For women but not men, the negative initial task produced a decrease in resting HF-HRV. This effect was mediated by the husbands' negative affect response to the task and their ratings of wives as controlling and directive. When the subsequent disagreement discussion followed the negative initial task, women displayed increased HF-HRV during the discussion but a decrease when it followed the neutral or positive task. The valence of the initial task had no effect on men's HF-HRV during disagreement. Negative marital interactions can reduce women's resting HF-HRV, with potentially adverse health consequences. Women's reduced health benefit from marriage might reflect the depleting effects on self-regulatory capacity of their greater efforts to manage relationship quality.     

Does mood influence the realism of confidence judgments?

Previous research has shown that mood affects cognition, but the extent to which mood affects meta-cognitive judgments is a relatively over-looked issue. In the current study we investigated how mood influences the degree of realism in participants' confidence judgments (based on an episodic memory task). Using music and film in combination, we successfully induced an elated mood in half of the participants, but failed to induce a sad mood in the other half. In line with previous research, the participants in both conditions were overconfident in their judgments. However, and contrary to our prediction, our data indicated that there was no difference in the realism of the confidence between the conditions. When relating this result to previous research, our conclusion is that there is no, or very little, influence of mood of moderate intensity on the realism of confidence judgments.     

How to trigger elaborate processing? A comment on Kunde, Kiesel, and Hoffmann (2003)

Recently, [Kunde, W., Kiesel, A., & Hoffmann, J. (2003). Conscious control over the content of unconscious cognition. Cognition, 88, 223-242] used a masked priming paradigm to argue that neither the 'elaborate processing' or the 'evolving automaticity' view can account for the processing of unconscious numerical stimuli. In our Experiment 1 we replicated [Kunde, W., Kiesel, A., & Hoffmann, J. (2003). Conscious control over the content of unconscious cognition. Cognition, 88, 223-242] Experiment 4 and show that with a less demanding mask than that used by Kunde et al., 'elaborate processing' can explain priming results given that there are side conditions to trigger elaborate processing of unconscious stimuli. The second experiment further explores this influence of the masks by increasing the relevance of the symbols by which the mask is composed. The results show that an increase in relevance of the mask is accompanied by a decrease in the priming effect, though there was no significant change in conscious awareness of the prime.     

Loneliness accentuates age differences in cardiovascular responses to social evaluative threat

The effects of aging and loneliness on cardiovascular stress responses were examined in 91 young (18-30 years) and 91 older (65-80 years) normotensive adults. Participants completed the revised UCLA Loneliness Scale and a modified version of the Trier Social Stress Test. Piece-wise linear growth-curve analysis was used to model group differences in resting, reactivity, and recovery levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Replicating and extending prior research, analyses revealed age-related increases in resting SBP and DBP. Adjusting for demographics and health covariates, interactions were found for SBP in which age differences in stress reactivity and recovery were greater among lonely than nonlonely participants. Findings provide further evidence that loneliness interacts with age to augment cardiovascular risk to social evaluative threat.     

Semantic priming in number naming

The issue of semantic and non-semantic conversion routes for numerals is still debated in numerical cognition. We report two number-naming experiments in which the target numerals were preceded by another numeral (prime). The primes and targets could be presented either in arabic (digit) notation or in verbal (alphabetical) notation. The results reveal a semantically related distance effect: Latencies are fastest when the prime has the same value as the target and increase when the distance between prime and target increases. We argue that the present results are congruent with the idea that the numerals make access to an ordered semantic number line common to all notations, as the results are the same for within-notation priming (arabic-arabic or verbal- verbal) and between-notations priming (arabic-verbal or verbal-arabic). The present results also point to a rapid involvement of semantics in the naming of numerals, also when the numerals are words. As such, they are in line with recent claims of rapid semantic mediation in word naming.     

How Colleagues Can Support Each Other's Needs and Motivation: An Intervention on Employee Work Motivation

Organisations have flattened and increasingly rely on teamwork. Therefore, colleagues play an increasingly important role in stimulating employee motivation. Adopting Self‐Determination Theory as a guiding framework, the aim of this field experiment was to examine whether team members can be trained in supporting each other's basic psychological needs for autonomy, competence, and relatedness and, hence, increase each other's need satisfaction and autonomous motivation, while decreasing controlled motivation. We delivered training to 146 participants nested in 26 participating teams and assessed basic need satisfaction and autonomous and controlled motivation before and after the intervention. Multilevel regression analyses indicated that employees in the experimental (i.e. intervention) condition had a stronger increase in need satisfaction and autonomous motivation than employees did in the control condition, and that the increase in autonomous motivation was mediated by an increase in need satisfaction. This study provides added value for theory on need satisfaction and demonstrates that a relatively brief intervention among team members may be effective in creating employee need support and increasing autonomous motivation.
