The purpose of this study was to examine the potential differences in selected acoustic measures of speech as a function of age, across sexes, and between families. The data used in this study were previously collected for a larger project on voice production at the University of Utah. Participants included 169 individuals, 79 men and 90 women, from 18 Utah families, ranging in age from 17 to 87 years. All participants had no history of articulation disorders, stroke or active neurologic disease, or severe-profound hearing loss. Participants were recorded reading two passages aloud in a sound booth. These two passages were selected as connected speech tasks from which to extract the following acoustic metrics: fricative spectral measures (center of gravity, standard deviation, skewness, and kurtosis), mean fundamental frequency (F0), semitone standard deviation (STSD), speaking time ratio, and cepstral peak prominence smoothed (CPPS). Results indicated significant aging effects on spectral center of gravity and skewness, mean F0, and STSD. There was a significant sex effect for spectral center of gravity and kurtosis, mean F0, speaking time ratio, and CPPS. Familial relationship had a significant effect for spectral skewness, STSD, and CPPS. Findings from the current study indicate that certain speech and voicing features point to a decline with age and that aging affects the speech of men and women differently. Additionally, these data suggest that related speakers may demonstrate similar patterns for prosody, voicing, and articulation behavior, although the statistical testing did not allow us to draw specific inferences about such similarities. These findings describe some normal variations in the speech production of persons of differing age, sex, and familial background. An understanding of these normal speech differences in healthy individuals is valuable for differentiating between typical and pathological speech patterns in a clinical setting.

Broad personality or global traits are unlikely to assist in solving capital crimes, so forensic psychologists have begun to focus on characteristics of the crime to create differentiating profiles. The purpose of this study was to determine if offender and victim characteristics and method of murder could provide cluster profiles differentiating familial relationship between offender and victim. Guided by classical conditioning theory and social learning theory, an archival database of 147 capital offenders responsible for 506 victims was analyzed. Cluster analysis yielded 3 distinct profiles. Compared to other clusters, Cluster 1 offenders tended to be Black and unfamiliar with their victims, who tended to be male between 20 and 50 years old that were typically shot. Cluster 2 offenders tended to be White and familiar with their typically female victims under the age of 20 who they typically murdered by use of blunt force or strangulation. Cluster 3 offenders were distinguished from the other 2 clusters only by having accounted for 90.6% of all victims who were stabbed, but no other associations with variables in the data set were discovered to explain this finding. Though limited in sample size, range of variables, and supplemental insights that could have been gained from case files or interviews, the results contribute to positive social change with offender-victim characteristics and method of murder profiles that begin to differentiate the familial offender-victim relationship and that future research can prospectively build on to create retrospective profiling models, which could potentially lead to resolving unsolved serial murder cases.

Introduction : Ces dernières années, les auteurs se sont attachés à créer une théorie générale de la problématique de la relation d’aide afin de mettre en évidence l’importance de la place occupée par les familles auprès du sujet âgé souffrant de la maladie d’Alzheimer. Il peut toutefois être intéressant de replacer l’aidant dans sa singularité de sujet affecté par d’autres questionnements que ceux relatifs à l’aide, afin de déterminer les facteurs influençant son vécu. Problématique : Dans quelle mesure la personnalité, les représentations du vieillissement, le lien de parenté et la qualité des relations passées vont influencer le vécu du rôle d’aidant principal d’un parent ou conjoint âgé en perte d’autonomie psychique, que ce dernier réside à domicile ou en institution ? Objectifs : Dans un premier temps, ce travail a pour objectif, d’établir les relations entre les différentes dimensions du vécu de l’aidant familial (difficultés, satisfactions et stratégies). Il se propose ensuite d’étudier l’influence sur ce vécu du lien de parenté et de l’entrée en institution d’une part, et de la personnalité (modèle en Cinq dimensions) et des représentations de la vieillesse d’autre part. Méthodologie : Pour ce faire, nous avons mené une étude auprès de 113 participants, dont 80 enfants et 33 conjoints. La première moitié accompagnait un proche à son domicile, la seconde en institution. Dans une première partie de l’étude, les participants ont rempli un questionnaire sociodémographique accompagné d’échelles évaluant la qualité des relations passées (QRASA), le fardeau (ZBI), les difficultés (CADI), satisfactions ressenties (CASI) et stratégies utilisées (CAMI) dans la relation d’aide, la personnalité (NEO PI-R) et la dépression (BDI). Dans un second temps, dix-sept participants ont été vus en entretien semi-directif afin d’appréhender qualitativement leur expérience d’aidant, les relations qu’ils entretiennent avec la personne accompagnée ainsi que leurs représentations de la vieillesse. Résultats : Les résultats de cette étude montrent que les difficultés, satisfactions ressenties et stratégies utilisées dans la relation d’aide sont liées entre elles, créant un équilibre nécessaire pour que l’aidant familial puisse investir son rôle. Cet équilibre est influencé aussi bien par des facteurs situationnels (lieu de résidence de la personne malade), relationnels (qualité des relations avec la personne accompagnée) que personnels (personnalité et représentations liées au vieillissement). Conclusion : Les implications en termes d’accompagnement et de prévention auprès de cette population sont discutées. / Introduction: Over the past years, authors have proposed a general theory of the caregiving relationship in order to highlight the importance of the place occupied by the families, who have an elderly relative suffering from Alzheimer's disease. However, it may be interesting to consider the caregiver with all his specificities, and as an individual affected by other problems than only the caregiving. We wonder to what extent the personality of a caregiver, the representations of the ageing process, the family relationship and the quality of the past relationships can influence the experience of caregiving. The studied caregivers were children or spouses of a patient losing his psychic autonomy, living at home or in an institution. Methods: We realized a study with 113 subjects (80 children and 33 spouses of an Alzheimer’s patient). Half of the patients were living at home and the other half in an institution. First, all caregivers filled a socio-demographic questionnaire and different clinical scales, assessing: the quality of the passed relationships (QRASA) ; the burden (ZBI) ; the difficulties (CADI ), satisfactions (CASI ) and strategies they used (CAMI) in the caregiving situations ; the personality (NEO PI-R) and the depression (BDI ). Second, 17 subjects have been seen in a semi-structured interview in order to qualitatively assess their experience of the caregiving, the past and present relationship they have with their parent or spouse. Results: The results of this study showed that the difficulties, the satisfactions which are experienced, and the strategies which are used in the caregiving relation are linked together. A balance between these variables is required for the family caregiver to invest his role. This balance is influenced by situational factors (the place where the patient lives), relational factors (the quality of the present and past relationship with the patient) as well as personal factors (personality and representations linked to the ageing process). Conclusion: The implications in terms of support and prevention for this population of caregivers are discussed.
