Examining the activity-distribution model of visual attention with exogenous cues and targets

LaBerge and his co-workers (e.g., LaBerge & Brown, 1986, 1989; LaBerge, Carlson, Williams, & Bunney, 1997) used an experimental method consisting of three rapid successive displays, each requiring a difficult letter discrimination, to show that visual attention is best accounted for with an activity-distribution model rather than a moving-spotlight model. The present study sought to further this line of investigation by inserting exogenous cues and targets, often used in studies that have found support for the moving-spotlight model, into the basic method used by LeBerge and colleagues. The results from three experiments were consistent with the activity-distribution model and not with the moving-spotlight model.     

Extraversion and Behavioral Activation: Integrating the Components of Approach

This investigation evaluates the structure and correlates of lower order traits related to approach, specifically, facets of extraversion and behavioral activation system (BAS) sensitivity. A 3-factor structure of approach was derived in community and clinical samples: assertiveness, enthusiasm, and sensation seeking. All factors were positively associated with Openness/Intellect scores. Enthusiasm and assertiveness were both negatively associated with Neuroticism scores, but were distinguished by associations with Agreeableness and Conscientiousness. Sensation seeking was negatively associated with Conscientiousness scores. The 3 factors demonstrated a unique profile of association with components of impulsivity. Enthusiasm and assertiveness were negatively related to psychopathological symptoms, whereas sensation seeking was largely independent of psychopathology. Results suggest that approach is associated with 3 subfactors, which differ in their pattern or magnitude of associations with other variables, thus underscoring the importance of distinguishing among them. Further, results support the construct validity of the Assertiveness and Enthusiasm aspect scales of the Big Five Aspect Scales to assess traits at this level of the personality hierarchy.

Neuropsychology Review - Mindfulness-based programs (MBPs) are increasingly utilized to improve mental health. Interest in the putative effects of MBPs on cognitive function is also growing. This...     

Integration or Sealing-Over. A Pilot Study of Coping Strategies of Severely Traumatised Patients

This article is an attempt to begin to weave together Freud's work - on dreams here envisioned as the original model for virtual reality - and from Fromm's work - on the impact of the market on personality. The contributions of these two psychoanalysts provide a necessary dual foundation for an understanding of emerging aspects of human psychology that are evolving, at the beginning of the 21st Century, alongside the profound influence of the electronically driven global market. It is time for psychoanalysis to engage more fully in the study of cultural forces. While it is easy to disregard dreams, both in the general culture and of late in psychoanalysis itself, dreams and their interpretation have always been central in human living, in the development of religion and in the birth of psychoanalysis as our own secular religion. Dreams, in their disembodiment and in their fluidity of information transformations have served as one model for developments within cyber culture and virtual living. The destruction of nature is seen as an underlying theme in the development of compatible relativist-subjectivist philosophies and in the growth of cyberculture. Thus, Freud's insights into dreams and Fromm's into the marketing personality are both crucial to an understanding of major contemporary forces.     

The Attention Training Technique as an Attempt to Decrease Intrusive Thoughts in Obsessive–Compulsive Disorder (OCD): From Cognitive Theory to Practice and Back

The attention training technique (ATT) is a cognitive treatment method that is aimed at ameliorating intrusive thoughts in anxiety disorders. To the best of our knowledge, no randomized controlled study has yet been conducted on individuals with obsessive–compulsive disorder (OCD). For the present study, we recruited 80 participants with OCD over the internet and allocated them to an experimental (ATT implemented as bibliotherapy) or a wait-list condition. Assessments were made at baseline and four weeks later. Groups performed similar at both time points on the self-report version of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Obsessive Compulsive Inventory-revised (OCI-R). The present study speaks against the effectiveness of ATT as a stand-alone bibliotherapeutical approach for OCD. From our data and increasing evidence that OCD patients do not suffer from severe attention or executive deficits we consider an approach targeting attentional biases for certain OCD-related events more useful than a generic (i.e., OCD-unspecific) cognitive remediation approach.     

Mentalisierungsdefizite bei stationären Patienten

Background

Fonagy (2009) considers the improvement of mentalization, understood as an element of structural change, as a global goal of psychotherapeutic treatment. Yet until now there is little knowledge about the mentalizing skills in clinical populations.

Material and methods

We examined the mentalizing skills in 201 patients on admission for complex psychotherapeutic inpatient treatment with the “Reading the mind in the eyes”-Test (RMET). We explored if there are diagnosis-related differences in the RMET and compared our findings to published data on the RMET in clinical and normal populations.

Results

Compared to normal populations our sample scored significantly lower in the RMET, however, no diagnosis-related differences were found.

Conclusions

Although our data are preliminary, psychotherapeutic inpatient treatment should consider the patients reduced mentalizing skills.     

Characteristics and organization of the worst moment of trauma memories in posttraumatic stress disorder

It has been proposed that the organization of the worst moment in traumatic memories (“hotspots”) is of particular importance for the development of PTSD. However, current knowledge regarding the organization and content of worst moments is incomplete.In the present study, trauma survivors with (n = 25) and without PTSD (n = 54) were asked to indicate the worst moment of their trauma and to give a detailed narrative of the traumatic event. The worst moment and the remaining narrative were analyzed separately with regard to organization and emotional content.Results indicated that worst moments of trauma survivors with PTSD differed from the remaining narrative and from worst moments described by trauma survivors without PTSD in that they were characterized by more unfinished thoughts, more use of the present tense and lower levels of cognitive processing. However, hypotheses regarding differentiating emotional content were not supported. Implications for our theoretical understanding of PTSD and potential therapeutic interventions are discussed.     

“Phobie à deux” and other reasons why clinicians do not apply exposure with response prevention in patients with obsessive–compulsive disorder

Meta-analyses suggest that exposure with response prevention (ERP) is the most efficacious treatment for obsessive–compulsive disorder (OCD) and treatment guidelines for the disorder accordingly recommend ERP. Despite this, many therapists, including those with a cognitive-behavioral therapeutic background, do not perform ERP in patients with OCD. The present study aimed to elucidate the reasons why. German therapists (N = 216) completed an anonymous online survey, the newly developed Reasons for Not Performing Exposure in OCD Scale (REPEX), that inquired whether, to what extent, and how they perform ERP in the treatment of OCD. We also asked their reasons for not applying ERP in the past. Most therapists considered ERP an efficient treatment for OCD. Marked differences emerged between physicians and psychologists, however. The former used exposure less often and for a shorter period, preferred in sensu to in vivo exposure, and conducted exposure less often in the personal environment of the patient than did psychologists. Both groups were familiar with clinical guidelines to a similar extent. A factor analysis of the REPEX scale revealed five factors. Patient lack of motivation, preference for exposure to be self-help as well as alleged organizational difficulties were endorsed most often. The latter was correlated with the age of the therapist and was far more often affirmed by physicians. Fear of side effects was named by a subgroup of clinicians; in the context of patient ambivalence, this may foster “phobie à deux”. Unlike prior research, lack of expertise was rarely identified as a reason not to use ERP. Recommendations for improving adherence to guidelines are discussed.     

Analysis of Cognitive Dysfunction in Patients with Low-Grade Glioma

All living adults with histopatologically proven diagnosis of low-grade glioma in a Swedish county were identified with help of the Regional Cancer Register, half of them (n = 24) participated in a neuropsychological evaluation. A considerable variation was found in cognitive function within this group of patients, ranging from good ability to severe disturbance. Different patterns of cognitive dysfunction emerged resulting in three subgroups; patients with severe, mild, and minimal selective dysfunction. The patients with severe disturbance had a global dysfunction covering most assessed cognitive domains. Slow information-processing speed was obvious in the subgroups with both severe and mild dysfunction. Cognitive problems present in the best performing group seemed related to tumor localization. Cognitive function in the whole sample was related to histopathological diagnosis of the tumor, as well as to educational level of the patients. The nonworking patients had significantly poorer performance than the working patients.     

Cluster analysis reveals distinct patterns of saccade impairment and their relation to cognitive profiles in Parkinson's disease

Saccade performance has been reported to be altered in Parkinson's disease (PD), however, with a large variability between studies as both motor and cognitive impairment interfere with oculomotor control. The aim of this study was to identify different patterns in saccade alterations in PD using a data-driven approach and to explore their relationship with cognitive phenotypes. Sixty-one participants with PD and 25 controls performed eye-tracking (horizontal and vertical prosaccades, antisaccades) and neuropsychological testing. Hierarchical cluster analysis was applied to the eye-tracking data to subsequently compare the clusters based on demographical, clinical and cognitive characteristics. The three identified clusters of saccade alterations differed in cognitive profiles from healthy controls, but not in PD-related motor symptoms or demographics. The rate of directive errors in the antisaccade task was increased in clusters 1 and 2. Further, cluster 1 was defined by a general disinhibition of reflexive saccades and executive dysfunction in the neuropsychological evaluation. In cluster 2, prolonged saccade latencies and hypometria were accompanied by multidomain cognitive impairment. The cluster 3 showed increased antisaccade latency and vertical hypometria despite lack of evidence for cognitive impairment. Our results suggest that there may be at least two opposing patterns of saccade alterations associated with cognitive impairment in PD, which may explain some of the contradictory results of previous studies.
