本研究采用创伤暴露程度问卷、父母与同伴依恋问卷、情绪调节策略问卷、DSM-5的PTSD症状核查表、创伤后成长问卷,以汶川地震8.5年后极重灾区的1153名青少年为被试,考察青少年的依恋、认知重评、表达抑制、PTSD和PTG之间的关系。结果发现：青少年的依恋可以直接负向预测PTSD、直接正向预测PTG;青少年的依恋可以通过认知重评负向预测PTSD、正向预测PTG,也可以通过表达抑制负向预测PTSD,却不能通过表达抑制预测PTG。     

Time–Frequency Cross Mutual Information Analysis of the Brain Functional Networks Underlying Multiclass Motor Imagery

To study the physiologic mechanism of the brain during different motor imagery (MI) tasks, the authors employed a method of brain-network modeling based on time–frequency cross mutual information obtained from 4-class (left hand, right hand, feet, and tongue) MI tasks recorded as brain–computer interface (BCI) electroencephalography data. The authors explored the brain network revealed by these MI tasks using statistical analysis and the analysis of topologic characteristics, and observed significant differences in the reaction level, reaction time, and activated target during 4-class MI tasks. There was a great difference in the reaction level between the execution and resting states during different tasks: the reaction level of the left-hand MI task was the greatest, followed by that of the right-hand, feet, and tongue MI tasks. The reaction time required to perform the tasks also differed: during the left-hand and right-hand MI tasks, the brain networks of subjects reacted promptly and strongly, but there was a delay during the feet and tongue MI task. Statistical analysis and the analysis of network topology revealed the target regions of the brain network during different MI processes. In conclusion, our findings suggest a new way to explain the neural mechanism behind MI.

Using Artist Trading Cards as an Expressive Arts Intervention in Counseling

Artist trading cards (ATCs) are miniature works of art that are created within the dimensions of standardized trading cards or playing cards (2.5 inches × 3.5 inches). ATCs can be made with a variety of media—everything from pen and ink to oil paints, collages, mosaics, stamping, and altered photos. Using this compact art format as an expressive arts intervention in the therapeutic environment provides the counselor with most, if not all, of the same therapeutic benefits of larger art media (e.g., expressive release, creativity, artistic communication, symbolic self-expression, self-exploration, etc.). The unique benefit of the ATC format is that ATCs allow for traditional expressive arts interventions to be “better, faster, and cheaper” in many ways.     

Adolescents' relationships with mother and father and their links to the quality of romantic relationships: A classification approach

Adolescents' relationships with parents are considered to be a major learning source and emotional base for developing expectations and styles of behaviour in close relationships. Using a longitudinal sample of late adolescents from nuclear families drawn from the German Family Panel pairfam (N = 720; mean age: 18.6 years), we investigated how adolescents' relationships with both parents influenced their romantic relationship quality one year later. Bagged (Averaged) Binary Recursive Partitioning was used to compare features of adolescents' relationships with mother and father (relatedness, negative conflict, emotional insecurity, and parental dominance) in respect of their importance in predicting similar aspects of romantic relationship quality. Overall, our findings suggest some degree of domain-specific continuities in adolescents' relationships with parents and partner, particularly for negative conflict, as well as more global effects for most features of the parent–adolescent relationship. Emotional insecurity with mother was most broadly linked to all features of adolescents' romantic relationship. Overall, adolescents' relationship with mother was found to be more influential than their relationship with father. The findings are discussed with reference to a behavioural systems perspective and attachment theory.     

A categorical approach to infants’ individual differences during the Still-Face paradigm

Cluster analysis was used to create patterns of individual differences reflecting infant behaviors during the initial interaction episode of the Face-to-Face Still-Face (FFSF) paradigm. The clusters were used as the basic unit of analysis for studying infant and maternal behavior and dyadic coordination (i.e., matching and reparation) across FFSF. Seventy-five 4-month-old infants participated with their mothers. Cluster analysis identified three patterns: a Socially Engaged cluster (33%) exhibited high levels of social engagement with their mothers; a Disengaged cluster (60%) showed a tendency to be low in social interaction and a Negatively Engaged cluster (7%) showed high negative emotionality. During the Still-Face episode, the Socially Engaged cluster reacted by reducing focus on their mother and shifting their attention elsewhere, while infants in the Disengaged cluster reduced focus on the environment. Although both the Socially Engaged and Disengaged clusters increased in negative emotionality during the Still-Face, the Socially Engaged group largely recovered during the Reunion, whereas the Disengaged group displayed more negative emotion. The Negatively Engaged cluster demonstrated high levels of negative affect throughout the entire procedure. Mothers of Negatively Engaged infants showed less positive engagement and more social monitoring than mothers in other clusters during all episodes. Dyadic interaction differed between groups, with greater levels of matching and reparations in the engaged group, less in the Disengaged group, and very little coordination in the Negatively Engaged cluster. Findings highlight the role of distinctive patterns of infants’ individual differences in determining early dyadic functioning.     

Modeling of 1-3 piezoelectric composites operating in thickness-stretch vibration mode

For bulk piezoelectric ceramics plates, the fundamental thickness-stretch (TSt) waves are always coupled to the in-plane extension waves and the symmetric thickness-shear waves. The occurrence of these spurious modes in bulk piezoelectric ceramics plates is undesirable as it may interfere with the operation of transducers. 1–3 piezoelectric composites are promising candidates to suppress the spurious modes mentioned above. However, theoretical modelling of multiphase ceramic composite objects is very complex. In this study, a simple analytical TSt vibration model is constructed from three-dimensional equations of linear piezoelectricity. The mechanical damping is considered in the model by introducing a complex elastic constant. The performance of 1–3 piezoelectric composites is analysed and the electrical impedance results from theoretical and experimental analysis are compared. The results show that there is excellent agreement between the experimental electrical impedance and that obtained by the theoretical TSt vibration analysis. This indicates that 1–3 piezoelectric composites can be operated in a nearly pure TSt vibration mode near the fundamental resonance. The analytical model we present is valid for analysing 1–3 piezoelectric composites plates with large aspect ratios quickly and efficiently.     

The integration of science and practice: Unique perspectives from counseling psychology students

Counseling psychology training programs predominately subscribe to the scientist–practitioner training model, which emphasizes the mutual integration of science and practice. There has been extensive debate surrounding the applicability of the scientist–practitioner training model to the field of counseling psychology, and existing commentary from both trainers and trainees has documented the potential challenges to adequately integrating science and practice. In the current article, three counseling psychology doctoral students outline their experiences in a program that adheres to the scientist–practitioner training model. In particular, they describe their involvement in both clinical and scholarly related activities, their experiences with the integration of science and practice, and how the scientist–practitioner model has influenced their overall professional development. Specific examples of how the scientist–practitioner model can shape the perspectives and career goals of psychologists-in-training are reviewed.
