Finding the Locus of Semantic Satiation: An Electrophysiological Attempt

The present study examined the effect of massed repetition of an initial category name upon the subsequent semantic categorization of a target word by means of an electrophysiological measure of semantic processing: the N400. Results showed the classic N400 effect, whereby evoked potentials were more negative for targets that were not members of the repeated category than for member targets. Moreover, repetition of the category name led to an increased and sustained positivity. The N400 effect was not modified, however, by repetition. Hence, insomuch as the N400 reflects meaning integration processes, these results do not support the hypothesis that massed repetition exerts its influence at the level of meaning integration.     

Being a therapist in eating disorder treatment trials: constraints and creativity

This paper gives a brief overview of the sequence and content of the eating disorder treatment trials at the Maudsley Hospital in London, and describes the experience of the author working as a research therapist on these trials. It considers the different ways research constraints affected the therapist, how she learnt to make creative use of what appeared to be therapeutic restrictions, and how having her clinical freedom curtailed taught her to be more flexible and showed her new ways of understanding her patients.     

Computing Cohen’s kappa coefficients using SPSS MATRIX

This short paper proposes a general computing strategy to compute Kappa coefficients using the SPSS MATRIX routine. The method is based on the following rationale. If the contingency table is considered as a square matrix, then the observed proportions of agreement lie in the main diagonal’s cells, and their sum equals the trace of the matrix, whereas the proportions of agreement expected by chance are the joint product of marginals. The generalization to weighted kappa, which requires an additional square matrix of disagreement weights, both matrices having the same order, becomes possible by the use of the Hadamard product-that is, the elementwise direct product of two matrices.     

Atemporalism and dependence

International Journal for Philosophy of Religion - It is widely thought that Atemporalism—the view that, because God is “outside” of time, he does not foreknow anything (rather,...     

Timelessness and freedom

One way that philosophers have attempted to defend free will against the threat of fatalism and against the threat from divine beliefs has been to endorse timelessness views (about propositions and God’s beliefs, respectively). In this paper, I argue that, in order to respond to general worries about fatalism and divine beliefs, timelessness views must appeal to the notion of dependence. Once they do this, however, their distinctive position as timelessness views becomes otiose, for the appeal to dependence, if it helps at all, would itself be sufficient to block worries about fatalism and divine beliefs. I conclude by discussing some implications for dialectical progress.

     

Predictors and outcomes of workplace violence and aggression

The authors developed and assessed the psychometric properties of an instrument measuring risk for workplace violence and expanded a model linking (a) risk and experience of violence and aggression from the public and (b) experience of aggression from coworkers to emotional well-being, psychosomatic well-being, affective commitment, and turnover intentions. Using data from 254 employees representing 71 different occupations, the measure demonstrated acceptable within-occupation and 1-month test-retest reliability. The data supported the model and showed that public-initiated violence and aggression and coworker-initiated aggression were differentially associated with personal and organizational outcomes.     

On the lateralization of emotional prosody: an event-related functional MR investigation

In order to investigate the lateralization of emotional speech we recorded the brain responses to three emotional intonations in two conditions, i.e., "normal" speech and "prosodic" speech (i.e., speech with no linguistic meaning, but retaining the 'slow prosodic modulations' of speech). Participants listened to semantically neutral sentences spoken with a positive, neutral, or negative intonation in both conditions and judged how positive, negative, or neutral the intonation was on a five-point scale. Core peri-sylvian language areas, as well as some frontal and subcortical areas were activated bilaterally in the normal speech condition. In contrast, a bilateral fronto-opercular region was active when participants listened to prosodic speech. Positive and negative intonations elicited a bilateral fronto-temporal and subcortical pattern in the normal speech condition, and more frontal activation in the prosodic speech condition. The current results call into question an exclusive right hemisphere lateralization of emotional prosody and expand patient data on the functional role of the basal ganglia during the perception of emotional prosody.     

Large-scale ensemble averaging of ambulatory impedance cardiograms

Impedance cardiography has been used increasingly to measure human physiological responses to emotional and mentally engaging stimuli. The validity of large-scale ensemble averaging of ambulatory impedance cardiograms was evaluated for preejection period (PEP), interbeat interval, and dZ/dt_(min) amplitude. We tested whether the average of “classical” 60-sec ensemble averages across periods with fixed activity, posture, physical load, social situation, and location could be accurately estimated from a single large-scale ensemble average spanning these entire periods. Impedance and electrocardiograms were recorded for about 24-h from 21 subjects. Recordings were scored by seven raters, using both methods for each subject. Good agreement (average intraclass correlation coefficient was .91) between both ensemble averaging methods was found for all three cardiac function measures. The results indicate that for unambiguous ambulatory impedance cardiograms, large-scale ensemble averaging is valid, which makes measuring prolonged changes in cardiac sympathetic activity by measuring ambulatory PEP feasible even in large epidemiological samples.     

Who takes driving licence point recovery courses in France? Comparison between course-takers and ordinary drivers

A self-administered questionnaire was answered by 2014 drivers, 853 of whom were taking a course. The data were analyzed aiming to identify the factors that are linked to taking the course, i.e. to recurrent reoffending.The course-takers, of whom 89% were male, admitted committing more violations than the control group. They had more accidents. More male course-takers than controls reported not being happy, and they more frequently had high extroversion scores.The multivariate analysis showed that, among men, taking the course was associated with the mileage, the feeling of being almost certain to be charged for an offence and having a high risk of losing one’s licence, in addition to being young, having a large number of brothers and sisters, higher socio-occupational category and smoking. Among women, in spite of the small number of them on the course, the mileage, the feeling of having a high risk of losing one’s licence, driving alone, the mental representation of their own vehicle as an extension of their office, and defining themselves as liking to take risks during leisure activities were significantly linked to taking a points recovery course.Those taking the course were not therefore doing so by chance; they differed from the general population of drivers, which was also precisely described with regard to driving habits and representations.Recommendations are then made in order to redirect the content of courses more towards introspection than technical matters.     

Predicting job seeking for temporary employment using the theory of planned behaviour: The moderating role of individualism and collectivism

Using the theory of planned behaviour (TPB), the role of behavioural, normative, and control beliefs and individualism/collectivism was examined in the context of job seeking for temporary employment. Data were collected in a two‐wave longitudinal design, using a culturally diverse sample of 138 temporary workers in The Netherlands. Results supported the TPB‐relationships, with the exception of the role of perceived behavioural control (PBC). Of the behavioural beliefs, sense of security, work–life balance, and status were most strongly related to intentions to seek temporary employment. Further, hypothesized moderating effects of collectivism were confirmed such that people low on collectivism were more strongly motivated by their personal attitudes about job seeking and less by perceptions of social pressure than people high on collectivism. Thus, the TPB was demonstrated to work somewhat differently depending on people's cultural value orientations.
