Executive functions and linguistic performance in SCD older adults and healthy controls

Subjective cognitive decline (SCD) might represent the preclinical phase of Alzheimer’s disease. Given the interest to characterize it, the present study explores (1) if there are differences in lexical retrieval (LexR) and sentence comprehension (SComp) between SCD and matched controls, and (2) the predictive value of demographic variables and executive functions in relation to LexR and SComp in each group. A sample of 135 participants voluntarily took part in this study (66 with SCD). They all completed the Trail Making, the Stroop, the Boston Naming, and the ECCO-Senior tests, as well as verbal fluency tasks (VF). Results show that (1) groups differ in LexR and in inhibition efficiency, and (2) VF is explained by years of formal education, particularly in the control group; SComp in the most complex items seems to rely in different strategies, related to flexibility in controls and to inhibition efficiency in SCD patients.     

Status Incongruence and Supervisor Gender as Moderators of the Transformational Leadership to Subordinate Affective Organizational Commitment Relationship

Grounded in role congruity theory, we examine how status incongruence (when the subordinate is older, has more education, work experience, and/or organizational tenure than the supervisor) in subordinate–supervisor dyads affects transformational leaders’ ability to foster affective organizational commitment among their subordinates. Across two field studies, our findings show that the relationship between transformational leadership and subordinate affective organizational commitment is less positive when status incongruence is high. Furthermore, in both field studies we found a 3‐way interaction among transformational leadership, status incongruence, and supervisor gender predicting subordinate affective organizational commitment. Specifically, in Study 1 (pink‐collar employees in Turkey), low status incongruence strengthened the positive relationship between transformational leadership and subordinate affective organizational commitment for male leaders. In Study 2 (pink‐collar employees in the United States), low status incongruence strengthened the positive relationship between transformational leadership and subordinate affective organizational commitment for female leaders. Furthermore, Study 2 also revealed that collective identity was a mediator of both the significant 2‐ and 3‐way interaction effects on subordinate affective organizational commitment.     

Counselling and psychotherapy as a form of learning: some implications for practice

This paper explores counselling and psychotherapy as a form of learning. Previous experiences may create distortions in meaning-making perspectives, distortions that create templates for evaluating future experience. These templates act as barriers to being open to experience; thus there is an inability to learn from experience. The process of therapy can provide a learning milieu for the exploration and working through of these barriers, with a potential outcome of a return to learning from experience. It is suggested here that intrinsic to the learning milieu created in therapy there are elements of significant, transformative and emotional learning. Therapy is thus a reparative discourse that facilitates a return to learning from experience. A deconstruction of this concept is provided here as a way of developing the exploration of counselling and psychotherapy as a form of learning.     

The lived experience of psychotherapists working with older clients: an heuristic study

This paper presents the results of an heuristic study based on the research question: ‘How do psychotherapists experience working with older clients?’ The question came from the researchers’ experience and interest in working with older clients in general practice. It started from the researchers’ desire to examine more closely feelings and elements present in their own experience in dialogue with seven other practising therapists who had an interest and experience of working with this client group. Qualities and elements identified were: perceptions of old age and ageism; boundaries and settings; changes to practice; culture and experiences; awareness of time; loss; decline and mortality; and parents and children. These are illustrated by material from each of the participants, a composite depiction of the experience, a creative synthesis and examples from the researchers’ experiences.     

RSK2 signaling in brain habenula contributes to place aversion learning

RSK2 is a Ser/Thr kinase acting in the Ras/MAPK pathway. Rsk2 gene deficiency leads to the Coffin-Lowry Syndrome, notably characterized by cognitive deficits. We found that mrsk2 knockout mice are unable to associate an aversive stimulus with context in a lithium-induced conditioned place aversion task requiring both high-order cognition and emotional processing. Virally mediated shRNA-RSK2 knockdown in the habenula, whose involvement in cognition is receiving increasing attention, also ablated contextual conditioning. RSK2 signaling in the habenula, therefore, is essential for this task. Our study reveals a novel role for RSK2 in cognitive processes and uncovers the critical implication of an intriguing brain structure in place aversion learning.     

High-fat diets impair spatial learning in the radial-arm maze in mice

It has been suggested that hyperglycemia and insulin resistance triggered by energy-dense diets can account for hippocampal damage and deficits of cognitive behaviour. We wonder if the impairment of learning and memory processes detected in diet-induced obese (DIO) mice is linked to diet composition itself. With this purpose we have evaluated learning performance in mice undergoing a short-term high-fat (HF) treatment, which leads to a pre-obese state characterized by increased adiposity without significant changes of glucose and insulin plasma levels. C57BL/6J mice were fed either a HF (45 kcal% from fat) or control diet (10 kcal% from fat) during 8 weeks. Learning performance was evaluated by using the four-arm baited version of the eight-arm radial maze test (RAM). Mice were trained to learn the RAM protocol and then memory was tested at different time-points. Time spent to consume food placed in baited arms and errors committed to find them were measured in all sessions. DIO mice significantly spent more time in learning the task and made a greater number of errors than controls. Moreover, retention tests revealed that both working and total memory errors were also more numerous in DIO mice. The current results show that short-term DIO impairs spatial learning and suggest that impairment of hippocampal learning elicited by HF diets might be perceptible before metabolic alterations linked to obesity develop.     

A cross-national comparison of aggressors, victims and defenders in preschools in England, Spain and Italy

There is a small, but growing, body of research investigating peer-victimisation between preschoolers, an age which has been identified as being important both theoretically and practically for the development of interventions. This study compares aggressive and defending behaviour and victim status of preschoolers in three European countries; England, Spain and Italy. The results provide further confirmation that some children behave aggressively towards their peers during preschool in each of the countries studied. There are similarities between preschool children involved in peer-victimisation in the three countries in terms of the roles taken, sex differences and the types of aggressive behaviours used and experienced by the children. There were differences in the profiles of children identified as taking the roles by teachers and peers. Overall, it was found that those children identified by peers or teachers as being aggressive were more likely to be male, rated as physically strong and more likely to be rejected by classmates. Also, in general, the targets of peer-victimisation differed depending on the reporter. Peer-nominated victims were not identifiable in terms of gender, popularity or physical strength. Teacher-nominated victims were more likely to be socially rejected and physically weak. There are several subtle differences between the countries which deserve further investigation. The findings are discussed in relation to furthering our understanding of the development of peer-victimisation in preschools and the need for interventions which address this phenomenon.     

Missing data imputation and corrected statistics for large-scale behavioral databases

This article presents a new methodology for solving problems resulting from missing data in large-scale item performance behavioral databases. Useful statistics corrected for missing data are described, and a new method of imputation for missing data is proposed. This methodology is applied to the Dutch Lexicon Project database recently published by Keuleers, Diependaele, and Brysbaert (Frontiers in Psychology, 1, 174, 2010), which allows us to conclude that this database fulfills the conditions of use of the method recently proposed by Courrieu, Brand-D’Abrescia, Peereman, Spieler, and Rey (2011) for testing item performance models. Two application programs in MATLAB code are provided for the imputation of missing data in databases and for the computation of corrected statistics to test models.     

Prevalence of Internet addiction in Latino adolescents with psychiatric diagnosis

Internet addiction (IA) is particularly relevant in the adolescent population. The aim of this study was to describe the prevalence of IA in a clinical sample of Latino adolescents receiving ambulatory psychiatric treatment. The correlation between their pattern of Internet use and their respective psychiatric diagnosis was also studied. Adolescent patients from the Psychiatric Ambulatory Clinic at the Pediatric University Hospital (N=71) completed the Internet Addiction Test (IAT) and a questionnaire about Internet use. Information regarding demographic and diagnostic data was retrieved from their clinical records. None of the subjects presented severe IA. A total of 71.8% (n=51) of the adolescents obtained scores reflecting no problem related to IA. Only 11.6% (n=5) of subjects have discussed Internet use with their therapist. Mood disorders showed a statistically significant (p=0.044) correlation with a higher score on the IAT. Mental health care practitioners must consider questions on Internet use as an essential part of the patients' evaluation given its significant correlation with diagnosis of a mood disorder.
