Discrimination of human and dog faces and inversion responses in domestic dogs (Canis familiaris)

Although domestic dogs can respond to many facial cues displayed by other dogs and humans, it remains unclear whether they can differentiate individual dogs or humans based on facial cues alone and, if so, whether they would demonstrate the face inversion effect, a behavioural hallmark commonly used in primates to differentiate face processing from object processing. In this study, we first established the applicability of the visual paired comparison (VPC or preferential looking) procedure for dogs using a simple object discrimination task with 2D pictures. The animals demonstrated a clear looking preference for novel objects when simultaneously presented with prior-exposed familiar objects. We then adopted this VPC procedure to assess their face discrimination and inversion responses. Dogs showed a deviation from random behaviour, indicating discrimination capability when inspecting upright dog faces, human faces and object images; but the pattern of viewing preference was dependent upon image category. They directed longer viewing time at novel (vs. familiar) human faces and objects, but not at dog faces, instead, a longer viewing time at familiar (vs. novel) dog faces was observed. No significant looking preference was detected for inverted images regardless of image category. Our results indicate that domestic dogs can use facial cues alone to differentiate individual dogs and humans and that they exhibit a non-specific inversion response. In addition, the discrimination response by dogs of human and dog faces appears to differ with the type of face involved.     

The Role of Attachment Representation in the Relationship Between Depressive Symptomatology and Social Withdrawal in Middle Childhood

We investigated the relationships among attachment representation, social withdrawal, and depressive symptomatology in childhood. A total of 326 children aged 8 to 10 years participated in the study. Children completed a family drawing procedure to assess attachment representation, the Children's Depression Inventory and the Social Withdrawal subscale of the Personality Inventory for Youth. Social withdrawal and attachment representations indicative of attachment dysfunction were each found to be positively correlated with depressive symptomatology. Further, attachment representation was found to significantly moderate the relationship between withdrawal and depression such that the positive relationship between withdrawal and depression was attenuated in the absence of attachment representations indicative of attachment dysfunction.     

The Assessment of Normal Fear in Children and Adolescents

Published research into normal fear now spans more than one century. During this time, a large number of papers have been published in the area. The resulting literature has led to a detailed understanding of normal fear experiences and, in particular, the ways in which they change with maturation. Of central importance, when evaluating the documented outcomes of this work, is the soundness of the methods and tools used in assessment. It is not surprising given the large number of researchers that have been involved in this area, that the assessment methods used have varied substantially. These have ranged from the methodologically problematic technique of obtaining retrospective adult reports to the administration of psychometrically validated fear survey schedules. An extensive review of this literature reveals that, for the last two decades, the fear survey schedule has been the most widely used technique for the fear assessment. The preference that has and is being demonstrated for the fear survey schedule as an assessment tool is most likely due to its many advantages including ease of use, objectivity in scoring, and provision of a substantial amount of information in a short period. However, despite its advantages, researchers and clinicians need to be cognizant of its potential limitations and, depending on the questions being asked, may need to consider using it in combination with alternative assessment strategies.

Longitudinal links between career adaptability and academic achievement in adolescence

Contemporary youth spend increasingly longer time in the educational system, where their career pursuits become closely intertwined with their educational goals. As career development is a life-long process, adolescents start working on their careers long before they engage in actual work behaviors. Therefore, in order for school to adaptively prepare youth for their future work lives, career adaptability and academic achievement should be reciprocally and positively linked throughout adolescence. To date, more longitudinal proof for these relations is needed. To address this shortcoming, we investigated cross-lagged associations between these two constructs in a three-wave longitudinal study, testing the moderating role of adolescents' gender, school type, and age. Participants were 1151 adolescents (41.3% boys), who completed the same paper-and-pencil measure three times across an academic year. Results showed positive reciprocal associations between career concern and academic achievement (i.e., Grand Point Average). This indicates that adolescents with a strong future orientation, who were already invested in career planning activities tended to perform better in school and vice-versa, high academic achievement further strengthened adolescents' positive outlooks on their vocational future. We also detected positive unidirectional links from academic achievement to career control and career confidence across one academic year. Interestingly, we did not find significant longitudinal links between career curiosity and academic achievement. These patterns of longitudinal relations applied equally to boys and girls, to those attending university-preparatory and work-bound schools, and to early-to-middle and middle-to-late adolescents. Research and applied implications of these findings are detailed.     

Confirmatory factor analyses of DSM-IV Cluster C personality disorder criteria

Notwithstanding its research and clinical relevance, the dimensionality and validity of the DSM-IV avoidant, dependent, and obsessive-compulsive personality disorders (PDs) criteria is still a largely unexplored topic. The aim of this study was to test the factor structure for DSM-IV Cluster C PD criteria in a sample of 641 consecutively admitted outpatients. Factor analysis results suggested that avoidant, dependent, and obsessive-compulsive PDs share a common latent dimension, and supported the three-factor structure of both observer and self-report ratings of DSM-IV Cluster C PD criteria. The pattern of factor loadings, however, was different from the one expected according to the DSM-IV classification.     

Child and Adolescent Emotion Regulation: The Role of Parental Emotion Regulation and Expression

This paper reviews current literature relating to parent and child emotional functioning, specifically their emotion regulatory skills and emotional expression. Included are considerations regarding theoretical, methodological, and sampling strengths and weaknesses of existing literature. On the basis of the review, several directions for future research are proposed. First, it is argued that consistency in the measurement of emotion regulation is necessary, including assessment of more refined theoretical conceptualizations of regulatory types, skills, or strategies. Second, it is argued that emotion regulation developmental research examining the post-early childhood period is necessary in order to contribute to a more comprehensive understanding of youths’ emotion regulation. Finally, it is argued that greater examination of paternal influences on child emotional functioning, in addition to maternal influences, is required. Consideration of these issues in future emotion regulation research will ideally contribute to a greater understanding of the mechanisms involved in child and adolescent development of optimal regulatory capacities.     

Relationships Between Parent and Child Emotion Regulation Strategy Use: A Brief Report

We examined the direct relationships between parent and child emotion regulation (ER) strategy use during the transitionary and understudied developmental periods of middle childhood through to adolescence. Three hundred and seventy-nine participants aged between 9 and 19 years, completed the Emotion Regulation Questionnaire for Children and Adolescents. In addition, 358 of their mothers and 207 of their fathers completed the Emotion Regulation Questionnaire. Providing partial support for the hypothesis, maternal use of the ER Expressive Suppression strategy was significantly predictive of their child’s use of Suppression. However, paternal ER strategy use was unrelated to their child’s ER strategy use. Child age did not moderate the relationships investigated. These findings suggest that children’s ER during middle childhood and adolescence is more closely related to the ER of their mother than their father. It is proposed that this may be accounted for by emotion socialization processes.
