Child and adolescent psychopathy: Assessment issues and treatment needs

The identification of psychopathic traits in childhood and adolescence is a topic of growing interest for scientific research. The development of models to predict violent behavior, together with efficient preventive and therapeutic programs, is a major goal when assessing youths with psychopathic traits. This paper focuses on the construct of child and adolescent psychopathy, while approaching historical and conceptual issues. By discussing the “state of the art” of the construct, we will analyze different instruments to assess psychopathy in children and adolescents, as well as the available treatment modalities. Finally, we will present possible lines for research and clinical intervention according to an evolutionary approach to anger and antisocial behavior.     

THE PROBLEM OF HEAVEN

An argument against the rationality of desiring to go to heaven might be put in the form of a trilemma: (1) any state of being that both lasts eternally and preserves me as the person I am would be hellish and therefore would not be a state of being that I could have any reason to desire; (2) any state of being that lasts eternally and yet fails to preserve my personhood by turning me into a non‐person would not be a state of being that I (qua person that I am) could have any reason to desire; and (3) any state of being that lasts eternally and yet fails to preserve my personhood by turning me into some other person would not be a state of being that I (qua person that I am) could have any reason to desire. This paper offers defenses of each of the three horns of this trilemma and concludes that there is no rationally compelling reason for any human being to desire to go to heaven.     

Reliability of the M-FLEX™: equipment to measure palmar grasp strength in infants

The palmar grasp behavior investigation is frequent in evaluation routine of infants. The aim of this study was to determine the reliability of an instrument for measuring palmar grasp strength in infants from birth to four months of age. Thirty-nine healthy infants from both sexes from birth to four months of age were evaluated and divided into three groups (“SC”, “FR”, “BL”) according to the city they came from. The equipment under test is called M-FLEX^®, which provides maximum grasp strength (FMAX), mean grasp strength (FMEAN) and grasp time (GRT) values. The repeatability and reproducibility of measures produced by the M-FLEX™ were verified. Three measurements were obtained (M1, M2, M3) from both hands, with the infant's face turned to the right. To calculate the repeatability, the three measures were compared to themselves in each group. For reproducibility, the difference between the averages of M1 of the three variables provided by M-FLEX™ was verified in the three sampling sites. The statistical tests used were ANOVA, Pearson's correlation and calculation of the intra-class correlation coefficient (ICC) with their respective confidence intervals (CI). The M-FLEX™ proved to be an outfit that provides measures capable of characterizing the palmar grasp phenomenon in infants.     

Measurement invariance of the Utrecht Work Engagement Scale for Students: A study across secondary school pupils and university students

School engagement is a multidimensional construct characterized by vigour, dedication, and absorption towards academic work that is related to school achievement. This study aimed to examine the measurement invariance of a school engagement measure – the Utrecht Work Engagement Scale-Students (UWES-S) – across secondary school pupils and university students. Two samples of secondary school pupils (n = 251) and university students (n = 229) were used. The results supported the original three-factor structure (vigour, dedication and absorption) of the UWES-S instead of a two- or a one-factor structure in both samples. Evidence for the metric and scalar invariance of the measure across secondary school pupils and university students was also found. The university sample had higher scores in vigour and absorption but not in dedication. These findings demonstrate that the UWES-S can be used for developmental studies where school engagement and its relation with other variables needs to be compared across distinct educational levels.     

The "anxiety state" and its relation with rat models of memory and habituation.

Rats selected as "anxious", "nonanxious," or normal according to their behavior in an elevated plus maze were submitted to memory tasks and the densities of central benzodiazepine receptors in the amygdala and the hippocampus were studied. Anxious rats exibited better retention scores in the inhibitory avoidance task while nonanxious rats exibited worse retention scores in inhibitory and two-way active avoidance tasks compared to normal rats. No significant differences were detected in the retention scores for habituation to an open field. Nonanxious rats presented a lower benzodiazepine receptor density in the hippocampus but not in the amygdala compared to the other groups. These data suggest that the benzodiazepine receptors are involved in the effect of "anxiety" or emotional states on memory storage processes.     

Psychometric Properties and Measurement Invariance of the Youth Psychopathic Traits Inventory - Short Version among Portuguese Youth

This study aimed to examine the psychometric properties of the Youth Psychopathic Traits Inventory - Short version (YPI-S) among a mixed-gender sample of 782 Portuguese youth (M = 15.87 years; SD = 1.72) collected in a school context. Exploratory and confirmatory factor analysis offered support for the expected 3-factor structure. Partial cross-gender measurement invariance and cross-sample measurement invariance of the YPI-S using a forensic sample of institutionalized males was established. The Portuguese version of the YPI-S showed adequate psychometric properties in terms of internal consistency, mean inter-item correlation, corrected item-total correlation, convergent validity, and discriminant validity. In support for criterion-related validity, the YPI-S also showed statistically significant associations with self-reported conduct disorder symptoms, alcohol abuse, and drug use. In terms of known-groups validity, males from the school sample scored lower than males from the forensic sample and higher than females from the school sample. The YPI-S seems to be a valuable brief and psychometrically reliable and valid self-report measure, which can be used to assess psychopathic traits in diverse samples of youth.     

Are you willing to pay the price? The impact of corporate social (ir)responsibility on consumer behavior towards national and foreign brands

This research examines how the country of origin (national vs. foreign) affects the relation between corporate social responsibility (CSR) and consumers' willingness to pay and purchase intention. In the study, we adopted a first‐price sealed bid auction approach, using money in a “real‐world” setting. The results showed that CSR/corporate social irresponsibility (CSIR) affects consumer behavior and, particularly, consumers' willingness to pay and purchase intention. The study supports both the moderation hypothesis of country of origin in the relationship between CSR/CSIR and willingness to pay and between CSR/CSIR and purchase intention. In the globalization context, these results have important implications for brands' communication and marketing strategy and can stimulate important insights in organizations. Future research directions and limitations are also discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Tablet Use in Young Children is Associated with Advanced Fine Motor Skills

Abstract

To evaluate whether frequent interactive tablet-use at preschool age is associated with improved fine motor skills and to describe tablet-use in young children. Cross-sectional study with 78 children, aged 24–42?months: group 1 with previous frequent tablet-use exposure (n?=?26), group 2 without previous tablet-use exposure (n?=?52). Fine motor skills were evaluated with the Bayley-III. Socioeconomic data and home environment quality were similar in both groups. Fine motor skills of group 1 were better than those of group 2 (p?=?0.013). Most participating children carried out passive and active tablet activities, usually accompanied by parents, not exceeding time recommendations for young age. We observed a difference in fine motor skills in young children slightly favoring those with tablet-use experience.     

Using multiple-tact training to produce emergent visual categorization in children with autism

Previous research has shown that children with autism spectrum disorder (ASD) can categorize visual stimuli without direct training when they can also tact these stimuli using a common name and behave as listeners in relation to this name. However, children usually learn to assign objects specific names prior to learning the category to which they belong. The current study replicated previous research and evaluated whether multiple-tact training would establish visual categorization (measured by a picture sorting test) and listener behavior. We used a nonconcurrent multiple baseline design across 2 children with autism spectrum disorder. After multiple-tact training, we assessed whether participants would visually categorize stimuli based on their common category name. Both participants categorized and engaged in the corresponding listener behavior.
