Speeded detection of vowels: A cross-linguistic study

In four experiments, listeners’ response times to detect vowel targets in spoken input were measured. The first three experiments were conducted in English. In two, one using real words and the other, nonwords, detection accuracy was low, targets in initial syllables were detected more slowly than targets in final syllables, and both response time and missed-response rate were inversely correlated with vowel duration. In a third experiment, the speech context for some subjects included all English vowels, while for others, only five relatively distinct vowels occurred. This manipulation had essentially no effect, and the same response pattern was again observed. A fourth experiment, conducted in Spanish, replicated the results in the first three experiments, except that miss rate was here unrelated to vowel duration. We propose that listeners’ responses to vowel targets in naturally spoken input are effectively cautious, reflecting realistic appreciation of vowel variability in natural context.     

Prevalence and severity of anxiety, depression and Type A behaviors in angina pectoris

The role of psychological factors in coronary heart disease was examined by administering the Bech Rating Scale (BRS) of mood disorders and the Jenkins Activity Survey (JAS) for Type A behavior patterns (TABP) to a consecutive sample of angina patients ( N = 94), to a consecutive sample of noncardiac patients ( N = 47), and to a random sample of adults from the general population ( N = 217). Anxiety and depression were both more frequent and more severe in angina patients than in noncardiac patients or in the general population. There was a tendency for certain components of TABP (i. e. speed, impatience, hard-driving and competitive disposition) to be elevated in angina patients, but a similar trend was noted in noncardiac patients. Although no consistent relations were observed between negative emotions and TABP scores in angina patients, their anxiety and depression scores were reliably related to their use of nitroglycerin. The findings concur with previous studies concerning the presence of anxiety and depression in patients with angina pectoris and indicate that such negative emotions are not closely related to Type A personality traits.     

La représentation sociale des droits de l'homme: Une recherche internationale sur l'étendue et les limites de l'universalité

La perception des violations des droits de l'homme par de jeunes individus insérés dans des contextes nationaux différents est-elle organisée selon des principes comparables à ceux d'experts ou d'institutions internationales? La présente étude contribue à élucider cette question en la situant dans le champ de la psychologie sociale. La représentation sociale des droits humains a été analysée par le biais d'un questionnaire standardisé soumis à des sujets de quatre pays (Costa Rica, France, Italie et Suisse) âgés de 13 à 20 ans. Les résultats montrent que les individus partagent dans une large mesure une conception institutionnelle des droits humains. De fortes variations à l'intérieur et entre les contextes nationaux apparaissent néanmoins, en particulier dans la délimitation des libertés individuelles et du contrôle étatique.     

Assessing muscular fatigue with a portable tremor measurement system suitable for field use

The utility of a portable tremor measurement system for detecting muscle fatigue was evaluated. Static arm extension was used to induce fatigue. A probe containing two accelerometers, held in the extended hand, recorded horizontal and vertical tremor oscillations in the 1- to 18-Hz range. Several summary amplitude and frequency measures were then derived to analyze hand/arm tremor in the unfatigued and the fatigued states. Large increases from unfatigued to fatigued states were observed in all of the amplitude measures in both axes. Summary frequency measures were far less sensitive to fatigue. Correlations between consecutively measured observations revealed high levels of reliability (r τ .80) in all of the amplitude measures, but not in the frequency measures. The most robust index of fatigue was the total power in the entire 1- to 18-Hz spectrum. The other amplitude measures, however, are suitable for examining the effects of fatigue in isolated portions of the spectrum.     

Measuring post-traumatic stress: A psychometric evaluation of symptom- and coping questionnaires based on a Norwegian sample

The purpose of this study was to evaluate the psychometric characteristics of the Norweigian versions of the Impact of Event Scale, the Post Traumatic Stress Scale-10 item version and General Coping Questionnaire-30 item version. A group of 40 male and 56 female medical students was tested one week and four months after having started dissection of cadavers for the first time. The results showed that all scales had good internal consistency and test-retest reliability. The student sample scored lower on the IES and PTSS-10 than comparable groups of traumatized subjects. A gender difference emerged, with female subjects scoring higher than male subjects. The factor analysis of the instruments indicated good construct validity for the symptom scales. The analysis of content validity related to DSM IV criteria indicated that the IES and PTSS-10 may have some limitations in their predictive validity of PTSD. Taken together, the three scales have shown good psychometric properties and could be used in future research and clinical work.     

'Weaving thoughts' A method for presenting and commenting psychoanalytic case material in a peer group

The authors argue that there are good reasons for seriously considering the dynamics of the peer group when discussing psychoanalytical case material. The setting and procedure have to protect and facilitate for the presenter and the group members to work together. The aim of this paper is to discuss the problems connected with presenting and discussing clinical psychoanalytical material in a peer group and to describe one such specifi c method, which the authors call the 'weaving thoughts' method. The design is primarily inspired by Bion's formulation 'thoughts in search of a thinker'. The group participants refl ect on the presented clinical material in a way that the authors metaphorically describe as creating a weave of thoughts that emerges from the material. The aim of the method is to facilitate a work-group climate that allows thoughts to wander about, and to avert group members from debating and compromising the integrity of its members by letting basic assumptions come into power. The method is described from theoretical and practical points of view, with two illustrations of seminars according to this design and fi nally a discussion of the advantages and drawbacks of the method.     

Mother-infant interaction and children's socio-emotional development with high- and low-risk mothers

Charting the dynamic character of mother-infant interaction requires using observational systems of sequential coding in real time. A longitudinal study was designed to approach maternal sensitivity in a more complex way using sequential analysis. The study was conducted with 20 high- and 20 low-risk mothers and their infants (aged: 3, 12 and 15 months) to examine the relation among mothers' risk status for physical abuse and their maternal interactive profiles, using micro-social sequential analyses, and the subsequent quality of attachment developed by their children at 15 months of age. Results showed significantly different timings in maternal responses in high- and low-risk groups, that the high-risk mothers were less sensitive: more intrusive and less discriminate regarding their infant's behavior. Significant differences between groups were also found after infant difficult behavior. High-risk mothers' infants were significantly more likely to develop insecure attachment. Sensitivity is proposed as a constellation of timings in early mother-infant interaction.     

SA-45: a brief form of the SCL-90

The Symptom Assessment-45 Questionnaire (SA-45) is a 45-item self-report instrument of psychiatric symptomatology derived from the original SCL-90. The SA-45 consists of nine 5-item scales assessing each of the same symptom domains as its parent instrument with no item overlap across domains. This paper provides preliminary validation of the Spanish version of the questionnaire in an undergraduate sample. Exploratory and confirmatory factor analyses supported a 9-factor structure, which corresponds to the nine proposed scales. Normative data, reliability (internal consistency) and validity were also examined, finding support for sound psychometric properties.     

Cognitive development, reading and prosodic skills in children with cochlear implants

This report summarizes some of the results of studies in our laboratory exploring the development of cognitive, reading and prosodic skills in children with cochlear implantation (CI). The children with CI performed at significantly lower levels than the hearing comparison group on the majority of cognitive tests, despite showing levels of nonverbal ability. The differences between children with CI and hearing children were most pronounced on tasks with relatively high phonological processing demands, but they were not limited to phonological processing. Impairment of receptive and productive prosody was also evident in children with CI. Despite these difficulties, 75% of the children with CI reached a level of reading skill comparable to that of hearing children. The results are discussed with respect to compensation strategies in reading.
