Analyzing feature distinctiveness in the processing of living and non-living concepts in Alzheimer’s disease

The conceptual structure account (CSA) is a model specifying the role of the living and non-living domain dichotomy in the structure of semantic memory. According to this model, feature distinctiveness and the perceptual–functional inter-correlation of concepts are assumed to play a major role in impairing the ability to discriminate between living and non-living concepts in Alzheimer’s disease (AD). The hypothesis was tested in this study by using naming and sorting tasks traditionally considered as assessing distinctiveness, and a property verification task where distinctiveness and perceptual–functional inter-correlation were objectively controlled against norms especially created for this purpose. Alzheimer’s patients (n = 59) with minimal, mild or moderate dementia and normal elderly adults (n = 31) participated in the study. Overall, the findings did not support the CSA predictions. They revealed a distinctiveness effect on response accuracy with shared features dominating distinctive features regardless of domain. They also revealed more difficulties in the tasks involving effortful processes. The results stress the need to consider both cognitive demands of tasks and structural aspects of knowledge in the evaluation of semantic memory in AD.     

Incorporating Religion/Spirituality Into Treatment for Serious Mental Illness

This paper examines whether religion and spirituality (R/S) should be incorporated into treatment for patients with serious mental illness. This question merits attention, especially in light of the strong presence of R/S in the United States and, in particular, among members of ethnic minorities. While the literature is somewhat mixed, prior research supports the view that incorporating adaptive R/S elements into treatment for patients with serious mental illness is beneficial, particularly for patients who do not exhibit severe psychotic symptoms. Drawing from our experiences in developing a family-focused Culturally-Informed Therapy for Schizophrenia (CIT-S), we will also highlight the importance of addressing spiritual issues within minority populations. In the second half of this paper, we will present several case illustrations of how R/S issues were used in CIT-S to help patients make sense of adverse situations and obtain much-needed support and coping resources outside the treatment room. Findings from this study indicate that religion and spirituality can often be incorporated into treatment in a way that coalesces with patients’ values and enhances treatment gains. Future research should investigate how therapists’ own R/S values interact with those of their clients, and whether congruency in R/S values has any impact on treatment efficacy.     

A hidden markov model-based analysis framework using eye-tracking data to characterise re-orientation strategies in minimally invasive surgery

Natural Orifice Translumenal Endoscopic Surgery (NOTES) represents a new paradigm in minimally invasive surgery whereby an operator uses a flexible instrument to navigate within an anatomical space. The flexible instrument is introduced via a natural body orifice such as the mouth to perform an operative intervention controlled by the surgeon without making incisions in the anterior abdominal wall. It differs from laparoscopic (traditional keyhole) surgery in two main ways: (1) the instruments used in NOTES are not rigid as in laparoscopic surgery and not specifically designed for this application; and (2) there are no incisions in the anterior abdominal wall. Disorientation during NOTES is a significant problem because as in laparoscopic surgery the operator typically uses a 2D camera-monitor interface for visualisation by the camera at the site of the operation. Furthermore, the positional cue offered by the external component (outside the body) of the camera is absent, and camera navigation is more cumbersome. When the operator is disorientated, it is important to be able to re-orientate quickly to minimise potential surgical errors. It is hypothesised that when surgeons become disorientated, there exist discrete patterns in psychophysical behaviour which are associated with effective re-orientation, and that these patterns are recognisable. In this study, we examine visual re-orientation behaviour in 18 subjects using eye-tracker data in a model comprised of selective image manipulation of everyday objects in a box trainer. We characterise effective behaviour using a fixation sequence similarity-based hidden Markov model. We show that the output of this algorithm is reliable in differentiating visual behavioural sequences, and that there are specific behavioural patterns and strategies associated with successful re-orientation in this model. Good re-orientation strategy appears to rely on identification and focus on a central object within the scene and judging position of its surrounding peripheral objects, suggesting integration of both geometric and feature information in a systematic way. Using selective, inconsistent feature cues for re-orientation were associated with less effective performance.     

Toward a Psychological Science for a Cultural Species

ABSTRACT— Humans are a cultural species, and the study of human psychology benefits from attention to cultural influences. Cultural psychology's contributions to psychological science can largely be divided according to the two different stages of scientific inquiry. Stage 1 research seeks cultural differences and establishes the boundaries of psychological phenomena. Stage 2 research seeks underlying mechanisms of those cultural differences. The literatures regarding these two distinct stages are reviewed, and various methods for conducting Stage 2 research are discussed. The implications of culture-blind and multicultural psychologies for society and intergroup relations are also discussed.     

Uncle Toros: Towards Understanding Genocide through Dreams

In the fictional short story “Uncle Toros,” an aging survivor of the Armenian genocide has a recurring nightmare in which he is visited by an image of a Turkish police chief who would recruit, from Uncle Toros's native village, Armenian youth for the military. This dream is studied in terms of its image of the walnut tree, rotation about it (the alchemical circulatio), elements of Kundalini yoga (especially a blockage in Uncle Toros's throat), the idea of sacrifice (real vs. psychological), and the Jungian archetypes of the collective unconscious. The problem of identification with evil for the Armenian is raised, along with the need for an Auseinandersetzung (confrontation) through the inner experience of the unconscious with its phantom narratives and healing strength of the feminine.     

Flow experience and the mobilization of attentional resources

The present study attempts to better identify the neurophysiological changes occurring during flow experience and how this can be related to the mobilization of attentional resources. Self-reports of flow (using a flow feelings scale) and attention (using thought probes), autonomic activity (heart rate, heart rate variability, and breathing rate), and cerebral oxygenation (using near-infrared spectroscopy) in two regions of the frontoparietal attention network (right lateral frontal cortex and right inferior parietal lobe) were measured during the practice of two simple video games (Tetris and Pong) played at different difficulty conditions (easy, optimal, hard, or self-selected). Our results indicated that an optimal level of difficulty, compared with an easy or hard level of difficulty led to greater flow feelings and a higher concentration of oxygenated hemoglobin in the regions of the frontoparietal network. The self-selected, named autonomy condition did not lead to more flow feelings than the optimal condition; however, the autonomy condition led to greater sympathetic activity (reduced heart rate variability and greater breathing rate) and higher activation of the frontoparietal regions. Our study suggests that flow feelings are highly connected to the mobilization of attentional resources, and all the more in a condition that promotes individuals’ choice and autonomy.     

Conflicts between parents and aggressive and delinquent behavior in children

The exposure of children to their parents' conflicts are a factor of substantial risk for the development of behavior problems in children. This study examines the relationship between marital conflicts and children's aggressive and delinquent behavior. The sample consisted of a total of 332 children, aged 7 to 17 years, and their mothers. The children completed the Children's Perceptions of Interparental Conflict Scale, providing information on the dimensions of the marital conflicts: frequency, intensity, no resolution, and content. The mothers completed the O'Leary Porter Scale, providing information about the frequency of conflicts, and the Child Behavior Checklist, about the aggressive and delinquent behavior problems in their children. The results indicate that parental conflicts affect sons and daughters equally, and they affect adolescents more than younger children when they are perceived by the children. However, conflicts affect all groups when the mothers perceive them.     

PISA and the assessment triangle

PISA is a well-known and high profile Program for International Student Assessment with 4 editions since 2000. This study aims to examine the validity of PISA proficiency estimates, working with the framework provided by the assessment triangle. We pay explicit attention to how PISA proceeds as far as the three elements of the assessment triangle are concerned: cognition, observation, and interpretation. Results reveal not only the psychometrically sound proficiency estimates of PISA and the high standards reached, but also that there is room for improvement; for instance, cognitive diagnostic models could contribute both to test design and data analysis.     

Perceptions of breastfeeding in mothers of babies born preterm in comparison to mothers of full-term babies

The purpose of the present study was: a) to describe the theme of verbalizations about breastfeeding in mothers' pre-term (M-PT) and full-term (M-FT) infants; b) to examine the association between these themes and mother's anxiety and depression indicators and socio-demographic characteristics and, neonatal characteristics of the infants. The sample consisted of 50 M-PT and 25 M-FT. The mothers were assessed through State-Trait Anxiety Inventory and Beck Depression Inventory and were interviewed using a Guide focusing breastfeeding issues. The M-PT group had significantly more mothers with clinical symptom of anxiety than the M-FT group. The M-PT reported more uncertainties and worries about breastfeeding and figured out more obstacles for the successful breastfeeding than the M-FT. These reports were associated positively with the infants' risk neonatal status; lower birth-weight, higher neonatal clinical risk, and more length time stay in NICU were associated with more mothers' worries and seeing obstacles for breastfeeding. In conclusion, the strategies to enhance the breastfeeding rate in the preterm population have to take into account the mothers' psychological status and their ideas in addition to offering information about the advantages of breastfeeding for child development.
