Deficits in prospective memory following damage to the medial subdivision of the mediodorsal thalamic nucleus

Identifying the neurocognitive mechanisms that lead individuals remembering to execute an intention at the right moment (prospective memory, PM) and how such mechanisms are influenced by the features of that intention is a fundamental theoretical challenge. In particular, the functional contribution of subcortical regions to PM is still unknown. This study was aimed at investigating the role of the medial subdivision of the mediodorsal thalamic nucleus (mMDT) in PM, with particular focus on the processes that are mediated by the projections from/to this structure. We analysed the performance of a patient (OG) with a right-sided lesion involving the mMDT in a series of PM tasks that varied for focality (i.e., overlapping of processes for the PM and ongoing tasks) and emotional valence of the stimuli, comparing the patient's performance with that of a control group. We found that the mMDT damage led to deficits in PM that were modulated by focality and emotional valence. OG indeed showed: a greater cost in the ongoing performance when a non-focal PM task was added; a slowing down in retrieving the intentions, in particular when these were associated with focal PM cues; an abnormal performance in the task with positive PM cues. Our findings provide evidence of a contribution of mMDT to PM and suggest a modulation of prefrontal-dependent strategic monitoring and a possible interaction with the limbic structures in the integration of emotion and PM processes. They also give support to the still controversial idea that connections with the perirhinal cortex mediate familiarity-based recognition.     

Algorithmic Proof Methods and Cut Elimination for Implicational Logics Part I: Modal Implication

In this work we develop goal-directed deduction methods for the implicational fragment of several modal logics. We give sound and complete procedures for strict implication of K, T, K4, S4, K5, K45, KB, KTB, S5, G and for some intuitionistic variants. In order to achieve a uniform and concise presentation, we first develop our methods in the framework of Labelled Deductive Systems [Gabbay 96]. The proof systems we present are strongly analytical and satisfy a basic property of cut admissibility. We then show that for most of the systems under consideration the labelling mechanism can be avoided by choosing an appropriate way of structuring theories. One peculiar feature of our proof systems is the use of restart rules which allow to re-ask the original goal of a deduction. In case of K, K4, S4 and G, we can eliminate such a rule, without loosing completeness. In all the other cases, by dropping such a rule, we get an intuitionistic variant of each system. The present results are part of a larger project of a goal directed proof theory for non-classical logics; the purpose of this project is to show that most implicational logics stem from slight variations of a unique deduction method, and from different ways of structuring theories. Moreover, the proof systems we present follow the logic programming style of deduction and seem promising for proof search [Gabbay and Reyle 84, Miller et al. 91].     

General and Realm-Specific Self-Efficacy: Connections to Life Functioning

This project examined how the synthesis of general and realm specific self-efficacy is related to life functioning. In two studies 760 participants provided information on their levels of general self-efficacy, specific self-efficacy in the realms of positive affect, sleep, exercise and study, and quality of functioning in these realms. Higher general self-efficacy was significantly associated with realm specific self-efficacy across the realms of positive affect, sleep, study, and exercise. Both higher general self-efficacy and higher realm-specific self efficacy were associated with positive affect, quality of sleep and study skills. Realm-specific self-efficacy mediated the relationships between general self-efficacy and functioning in the realms of positive affect, sleep, and study. Structural equation modeling indicated paths from general self-efficacy to latent variables comprised of realm-specific self-efficacy. Different types of realm-specific self-efficacy together contributed to explaining variance in general self-efficacy. The results provide support for a hierarchical model of self-efficacy. The findings provide a platform for future longitudinal research and experimental intervention research examining the causal inter-relationships of general self-efficacy, realm-specific self-efficacy, and functioning.     

Motion influences gaze direction discrimination and disambiguates contradictory luminance cues

In two experiments, we investigated the role of apparent motion in discriminating left/right gaze deviation judgments. We demonstrated that discrimination accuracy and response confidence was significantly higher when the eyes were moved to the left or right, compared to when the eyes were presented in their final shifted position (static images). To dissociate the role of motion signals from luminance signals, gaze stimuli were also presented in reverse contrast. Replicating past studies polarity reversal had a profound and detrimental effect on gaze discrimination in static images, although, intriguingly, while response confidence remained low, participant performance improved as gaze angle increased. In striking contrast to these data, polarity reversal had no negative effect on performance when the eyes were moved. We discuss these findings in the context of a multiple-cue account of gaze perception.     

One size doesn’t fit all: the influence of supervisors’ power tactics and subordinates’ need for cognitive closure on burnout and stress

The present research investigated the notion of fit between supervisors’ power tactics and subordinates’ need for cognitive closure (NFCC) on subordinates’ burnout and stress. Subordinates who tend to avoid ambiguity (high NFCC) were expected to experience relatively less burnout (Study 1) and stress (Study 2) if their supervisors utilize harsh (controlling and unequivocal) power tactics and more burnout and stress if their supervisors utilize soft (autonomy-supportive and equivocal) power tactics. In contrast, it was expected that subordinates who avoid firm and binding conclusions (low NFCC) would experience relatively less burnout and stress if their supervisors use soft power tactics and more burnout and stress if they use harsh power tactics. Two studies conducted in diverse organizational settings supported these hypotheses. Collectively, these results support the conclusion that soft (vs. harsh) power tactics are not always associated with better (vs. worse) organizational outcomes. Theoretical and practical implications for organizations are discussed.     

Fluctuation of Flow and Affect in Everyday Life: A Second Look at the Paradox of Work

Studies with the Experience Sampling Method (ESM) have shown that individuals experience more flow at work than at leisure. This indicates that people enjoy working but paradoxically at the same time leisure activities are preferred (“paradox of work”). We took a second look at the paradox of work by measuring flow directly, including affect measures, and differentiating between active and passive leisure activities. We also adopted a dynamical approach based on the idea that the transitions of experiences has to be taken into account to get the total picture. For the period of 1 week, data of 100 employees with different professions were collected with the ESM (in total 4,504 measurements). In accordance with existing work, we found that flow was high during work. It was slightly (albeit significantly) higher than during active leisure activities and considerably higher than during passive leisure activities. At the same time, negative activation was low during passive and active leisure activities and lower than during work and vice versa for valence (happiness). Thus, leisure activities do have a positive affective quality that could explain why people prefer leisure to work. Regarding the dynamical approach, we tested whether flow during work would lead to higher valence in leisure but could not support this assumption. We discussed the findings and made suggestions for future research. In an additional analysis, we reveal that perceived outcome experience could partially explain why work and leisure experience differed.     

Technology,Phenomenology and the Everyday World: A Phenomenological Analysis on How Technologies Mould Our World

Technology always provides a new perception of the world. However, it is not clear when technology produces “mere” new informations and when it provides something more such as a production of new objects in our world which start to “live” around us. The aim of this paper is to study how technology shapes our surrounding world. The questions which we are going to answer are: Is it really adding new objects to our world? If yes, does every technology have this potentiality? We are going to tackle the problem using a phenomenological and post-phenomenological approach focussing our attention on the perceptual level. Using Husserl’s philosophy we will study how technology are deeply involved in our perception and, thanks to post-phenomenology and its concept of “embodiment relations,” we will be able to determine which kind of technologies have the potentiality to change our surrounding world introducing and producing new objects in it.     

Dynamic interpersonal therapy in an NHS tertiary level specialist psychotherapy service

We describe the introduction of dynamic interpersonal psychotherapy (DIT) into an National Health Service (NHS) tertiary psychoanalytic specialist psychotherapy service. Training in DIT began as our contribution to Improving Access to Psychological Therapies and primary care services, supporting the training and supervision of their DIT practitioners. We then discovered DIT could be a valuable treatment within our own tertiary NHS service for patients with complex presentations. Currently fighting for survival, like many NHS psychoanalytic psychotherapy services nationally, we have adopted a manual-guided, psychoanalytically based therapy to broaden our tertiary clinical psychoanalytic service and accommodate trends in mental health service provision, whilst protecting the quality and integrity of our psychotherapy. DIT helped us continue providing relevant and beneficial psychoanalytic and psychodynamic services to individual patients despite limitations of the financially challenged NHS, NICE guidelines and Payment by Results. We outline the progress and outcomes for patients with complex mental health presentations, include individual case discussion and our experience of using the DIT approach within a traditionally longer term psychoanalytic psychotherapy service.     

Psychological adjustment to cleft lip and/or palate: A narrative review of the literature

Objective: Adjustment to cleft lip and/or palate (CL/P) is multifaceted, involving several domains of psychological and social functioning. A substantial increase in research in this area has been evident in recent years, along with a preliminary shift in how adjustment to CL/P is conceptualised and measured. An updated and comprehensive review of the literature is needed in light of the rapidly expanding and changing field.

Design: A narrative review of 148 quantitative and qualitative studies published between January 2004 and July 2015.

Main outcome measures: Findings are presented according to five key domains of adjustment: Developmental Trajectory, Behaviour, Emotional Well-being, Social Experiences and Satisfaction with Appearance and Treatment. Data pertaining to General Psychological Well-being were also examined.

Results: The overall impact of CL/P on psychological adjustment appears to be low. Nonetheless, the review demonstrates the complexity of findings both within and across domains, and highlights recurring methodological challenges.

Conclusions: Research findings from the last decade are considered to be largely inconclusive, although some areas of emerging consensus and improvements in the approaches used were identified. Efforts to collect data from large, representative and longitudinal samples, which are comparable across studies and encompassing of the patient perspective, should be doubled.
