Construct and concurrent validity of the Cambridge neuropsychological automated tests in Portuguese older adults without neuropsychiatric diagnoses and with Alzheimer’s disease dementia

We aimed to analyze the construct and concurrent validity of the Rapid Visual Information Processing (RVP), Paired Associates Learning (PAL), Reaction Time (RTI), and Spatial Working Memory (SWM) tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB®). Inclusion criteria were checked in a first session. The CANTAB and additional pencil-and-paper tests were administered within 1 week. The participants (aged 69–96 years) were 137 Portuguese adults without neuropsychiatric diagnoses and 37 adults with mild-to-moderate Alzheimer’s disease dementia. Comparisons were made between the CANTAB tests and between these tests and the Rey Complex Figure Test (RCFT), Verbal Fluency (VF) test, and some Wechsler Memory Scale-III and Wechsler Adult Intelligence Scale-III subtests. Most intra-test correlations were stronger than the CANTAB inter-test correlations. The RVP correlated more with VF animals (.44), the PAL with RCFT immediate recall (–.52), the RTI with RVP mean latency (.42), and the SWM with Spatial Span backward (–.39).     

Life Satisfaction and Character Strengths in Spanish Early Adolescents

This study of Spanish early adolescents aimed to extend knowledge about the relationship between character strengths and life satisfaction (LS) and to explore gender differences in the prediction of LS. A sample of 457 adolescents aged 11–14 years completed questionnaires to assess LS and 24 character strengths. Results from simple correlation analysis showed that 18 strengths were positively and significantly correlated with LS, the highest coefficients being those for love, hope, authenticity and persistence. However, since strengths are inter-correlated, regression modelling was performed in order to determine which of these strengths are the best predictors of LS, and to identify any gender differences in this association. The results showed that love and hope were the most relevant strengths for predicting LS, with a positive relationship being observed for both girls and boys. This finding highlights the importance of positive thinking and of maintaining positive relationships during early adolescence. Gender differences were observed, however, for authenticity as a predictor of LS. Specifically, this variable made a significant contribution to the model in girls, for whom higher scores on authenticity were associated with greater LS. This result is interpreted in terms of gender differences in the timing of maturation. The findings help to further our understanding of the association between subjective well-being and character strengths in early adolescence, a critical stage of human development. In addition, the results suggest that intervention programmes based on character strengths in this developmental stage should mainly target the so-called ‘strengths of the heart’.     

The Polish adaptation of the Early Childhood Behavior Questionnaire (ECBQ): Psychometric properties,age and gender differences and convergence between the questionnaire and the observational data

The main aim of the study was to determine the psychometric properties of the version of the Early Childhood Behavior Questionnaire (ECBQ) adapted to Polish culture. Since temperament in toddlers was being observed in a laboratory, an external validity of the ECBQ was also provided. Kagan’s observational paradigm was used to test 215 18-month-old children. Their parents completed the ECBQ twice, when the children were 26 and 30 months old. The results showed good internal consistency and confirmed the longitudinal stability of the scale. The same three-factor solution was found in the structure of the scale as in the original American study. The convergence between the observational and parent report data supported the ECBQ’s external validity. Similarities in the structure of the scale observed between the Polish and American data are discussed from a cross-cultural perspective. The usefulness of the Polish ECBQ and the limitations of the obtained results are discussed.     

Young People and Volunteerism: A Model of Sustained Volunteerism During the Transition to Adulthood

A model of sustained volunteerism in young people is proposed. The longitudinal study addresses the questions “Why do young people decide to continue to volunteer over an extended period of time?” There were 158 volunteers (82 female and 76 male). The volunteers completed measures of motivation to volunteer, integration, and satisfaction with the organization, merged effects due to voluntary service, social support, identity, and intention to volunteer on a first (Time 1) and a second research wave (Time 2). Results show that both dispositional and organizational variables are important in determining long-term volunteerism in young people and confirmed that role identity is the best predictor of intention to volunteer.     

An interruption in unconscious communication in the analytic couple

The authors describe an interruption in communication in the analyses of two patients, which gradually brings the analytic process to a halt/standstill. They propose several hypotheses for understanding this situation. One explanation is mutual identification of primitive superegos in the analytic couple which generates a moralizing effect thereby hindering investigation and discovery. They emphasize the importance of countertransference involvement which partly provokes this particular type of impasse. They also suggest the idea of shared acting out, with complementary participations of analyst and patient. In this way the analytic couple supports a 'bastion' which protects against the risk of breaking the omnipotence of patient and analyst or contributes to this omnipotence. Their shared unconscious phantasy feeds collusion linked to unconscious persecutory guilt. The authors also describe movements to break free from this impasse. The enclave created by the analytic couple is detected and subsequently worked through by way of the patient's contribution of dream material and the analyst's work with her countertransference.     

Effects of internal clock and memory disorders on duration reproductions and duration productions in patients with Parkinson's disease

Patients with Parkinson's disease (PD) exhibit deficits in perceptual and motor timing as well as impairments in memory and attentional processes that are related to dysfunction of dopaminergic systems in the basal ganglia. The aim of the present study was to assess the relationships existing between impaired duration judgments and defective memory and attention in PD patients. We compared time performance of medicated PD patients and control subjects on a duration reproduction task that is highly memory-dependent, and on a duration production task that could reveal effects of changes in the speed of internal time-keeping mechanisms. Each task was performed in a control counting condition and in a condition requiring divided attention between the temporal task and a concurrent reading task. Moreover, PD patients and control subjects were assessed on memory and attention using a battery of neuropsychological tests. The results revealed that in the concurrent reading condition of the reproduction task, duration judgments tended to be more variable in PD patients than in control subjects. Moreover, variability of duration reproductions was correlated with both measures of memory and of disease severity. In the concurrent reading condition of the production task, duration judgments were significantly shorter in PD patients than in control subjects, and accuracy of duration productions was correlated with scores on sub-tests of short-term memory. The findings suggest that the administration of dopamine did not entirely remove the memory deficits in PD patients. Moreover, DA treatment would have abnormally accelerated the rate of the internal clock leading to shorter duration productions in PD patients. The whole results indicate that dopamine administration in patients might have overshadowed the slowing rate of the internal clock usually reported in non medicated PD patients, without entirely restoring all of the memory functions.     

MONITORING CONSCIOUS RECOLLECTION VIA THE ELECTRICAL ACTIVITY OF THE BRAIN

Abstract— Although another person's experience of recollection cannot be observed directly, we have found that the underlying operations can be monitored using noninvasive electrophysiological techniques. Results from two experiments showed that brain potentials elicited 500 to 900 ms after the onset of visually presented words vary systematically in amplitude with manipulations that influence the extent to which subjects engage in recollective processing. These brain potentials can thus be construed as correlates of the subjective experience of recollection     

Music-to-language transfer effect: may melodic ability improve learning of tonal languages by native nontonal speakers?

In tonal languages, as Mandarin Chinese and Thai, word meaning is partially determined by lexical tones. Previous studies suggest that lexical tones are processed by native listeners as linguistic information and not as pure tonal information. This study aims at verifying if, in nontonal languages speakers, the discrimination of lexical Mandarin tones varies in function of the melodic ability. Forty-six students with no previous experience of Mandarin or any other tonal language were presented with two short lists of spoken monosyllabic Mandarin words and invited to perform a same–different task trying to identify whether the variation were phonological or tonal. Main results show that subjects perform significantly better in identifying phonological variations rather than tonal ones and interestingly, the group with a high melodic ability (assessed by Wing subtest 3) shows a better performance exclusively in detecting tonal variations.
