Hypnotic assessment based on the Recurrence Quantification Analysis of EEG recorded in the ordinary state of consciousness

The cerebral cortical correlates of the susceptibility to hypnosis in the ordinary states of consciousness have not been clarified. Aim of the study was to characterize the EEG dynamics of subjects with high (highs) and low hypnotisability (lows) through the non-linear method of Recurrence Quantification Analysis (RQA). The EEG of 16 males – 8 highs and 8 lows – was monitored for 1 min without instructions other than keeping the eyes closed, being silent and avoiding movements (short resting), and during 15 min of simple relaxation, that is with the instruction to relax at their best. Highs and lows were compared on the RQA measures of Determinism (DET) and Entropy (ENT), which are related to the signal determinism and complexity. In the short resting condition discriminant analysis could classify highs and lows on the basis of DET and ENT values at temporo-parietal sites. Many differences in DET and all differences in ENT disappeared during simple relaxation, although DET still separated the two groups in the earliest 6 min of relaxation at temporo-parietal sites. Our RQA based approach allows to develop computer-based methods of hypnotic assessment using short-lasting, single channel EEG recordings analyzed through standard mathematical methods.     

Considering spatial ability in virtual route learning in early aging

The aim of this study is to broaden our understanding of the construction and early decline of spatial mental representations in route learning, considering the extent to which spatial ability and age-related differences in environment learning interact. The experiment examines spatial mental representation derived from taking a realistic route acquired using virtual environment and compares individuals different in age but with similar spatial ability. A sample of 34 young (20–30 years) and 30 middle-aged (50–60 years) females with good mental rotation ability were chosen. Participants learned a complex route through its presentation in a virtual environment and then performed a series of tasks (landmark recognition, location of landmarks and verification of spatial relations). Results show that the two participant age groups had similar performance in landmark recognition task and in verification of sentences describing direct spatial relations; instead, the middle-aged group showed a poorer performance than younger in their ability to locate landmarks and to judge the truth of indirect spatial sentences. These results first suggest that spatial abilities have to be seriously considered to avoid any confusion with age, as age-related differences are attenuated when individuals are different in age but similar in spatial ability. Second they confirm a specific difficulty of older participants to handle spatial information in a global configuration.     

The Impact of Criminalization of Stalking on Italian Students: Adherence to Stalking Myths

Although behaviors that we today identify as stalking have occurred throughout history, the recognition and systematic investigation of stalking are quite recent. Italy’s antistalking law is fairly new, and factors such as cultural myths, stereotypical beliefs, and definitional ambiguities continue to cause problems in the interpretation and recognition of stalking among the general public. This study examined perceptions and attitudes of 2 groups of Italian criminology students at 2 different times, before and after the implementation of Italy’s 2009 antistalking law. The Stalking Attitudes Questionnaire (McKeon, Ogloff, & Mullen, 2009) was administered to samples in 2007 and 2010. Results revealed significant changes in some beliefs and attitudes between the pre- and post-assessments. Interpretation suggests that the combination of Italian antistalking legislation and increased attention to research seem to have decreased students’ adherence to stalking myths.     

Perceiving facial expressions

Three experiments investigated the perception of facial displays of emotions. Using a morphing technique, Experiment 1 (identification task) and Experiment 2 (ABX discrimination task) evaluated the merits of categorical and dimensional models of the representation of these stimuli. We argue that basic emotions—as they are usually defined verbally—do not correspond to primary perceptual categories emerging from the visual analysis of facial expressions. Instead, the results are compatible with the hypothesis that facial expressions are coded in a continuous anisotropic space structured by valence axes. Experiment 3 (identification task) introduces a new technique for generating chimeras to address the debate between feature-based and holistic models of the processing of facial expressions. Contrary to the pure holistic hypothesis, the results suggest that an independent assessment of discrimination features is possible, and may be sufficient for identifying expressions even when the global facial configuration is ambiguous. However, they also suggest that top-down processing may improve identification accuracy by assessing the coherence of local features.     

“Don't throw the baby out with the bathwater!” Interpersonal strain at work and burnout

Interpersonal strain represents the feeling of discomfort and disengagement in the relationships with people at work resulting from exceeding social requests and pressures. This article has three aims: (1) to introduce the Interpersonal Strain at Work scale (ISW), (2) to examine its construct validity and reliability, and its relationship with the Maslach Burnout Inventory exhaustion and cynicism; and (3) to test the generalizability of the ISW across different work settings. Multilevel CFA on two samples of call centre agents (5407) and hospital professionals (753), nested in 191 and 43 units, respectively, confirmed the good psychometric properties of the ISW and its distinctiveness from established burnout dimensions. The generalizability of ISW was also supported. Interpersonal strain at work seems to be a promising construct to recapture the interpersonal nature of the burnout syndrome that was lost when the concept of burnout was extended beyond the human services.     

Personal and social aspects of professional identity.: An extension of Marcia's identity status model applied to a sample of university students

The study proposed an extension of Marcia's identity status model based on validation of the Professional Identity Status Questionnaire (PISQ-5d), a scale able to measure both intra-individual and intergroup processes connected with the development of a professional identity in university students. The aims were to prove the construct validity of the PISQ-5d, to determine the appropriate number of identity statuses, and to assess the concurrent validity of the identity statuses considering both job-related and academic factors. In this study, 477 university students completed a questionnaire with the PISQ-5d scale; 220 also completed the measures of work values; and 168 completed the measures of student self-esteem and self-efficacy, academic motivation, and grades. Results confirmed the expected five-dimensional structure of the PISQ-5d and the scale's effectiveness at differentiating five types of identity status. Relationship between professional identity status and job-related and academic factors showed that the students with achievement or foreclosure identities had higher scores on measures of academic self-esteem and intrinsic work value and had lower scores for intention to leave university. Implications in terms of considering the PISQ-5d scale a useful tool for the evaluation of professional identity construction processes in university students will be discussed.     

Psychometric Properties of the Italian Version of the Psychological Capital Questionnaire

Two studies were conducted in order to investigate the psychometric properties of Italian version of the Psychological Capital Questionnaire (PCQ). Results from Study 1 (N = 401) provided support of the factorial validity of its four facets (self‐efficacy, optimism, hope, and resilience), as well as of its composite factor measure. Results from Study 2 (N = 465) attested the measurement invariance of the PCQ across one year. Study 2 also explored the relationship between psychological capital, job satisfaction, work engagement, and job performance. Limitations and practical implications are discussed in the article.
