ERP correlates of target–distracter differentiation in repeated runs of a continuous recognition task with emotional and neutral faces

The emotional salience of faces has previously been shown to induce memory distortions in recognition memory tasks. This event-related potential (ERP) study used repeated runs of a continuous recognition task with emotional and neutral faces to investigate emotion-induced memory distortions. In the second and third runs, participants made more false alarms to distracters (repeated from previous runs). Emotion did not modulate the amount of errors, but the extent to which recollection was employed to maximise performance as reflected in the putative ERP correlate of recollection; the parietal old–new effect. Targets from all stimulus classes (positive, negative, neutral) were associated with parietal ERP memory effects, but this was also the case for correctly rejected negative distracters. This suggests that recollection was strategically used to correctly reject negative distracters (recall-to-reject). This finding is consistent with the view that facilitated recollection of negative stimuli may be used to decrease the susceptibility to memory errors induced by emotional salience.     

A comparison of impulsivity and sensation seeking in pathological gamblers and skydivers

The aim of this study was to compare pathological gamblers and skydivers in relation to measures of impulsivity and sensation seeking. The Eysenck Impulsivity Scale - Narrow Impulsiveness Subscale and the Arnett Inventory of Sensation Seeking were administered to pathological gamblers (n = 29), skydivers (n = 93), and a control group (n = 43). A two-way multivariate analysis of variance was conducted to explore differences in impulsivity and sensation seeking between the groups and possible group by gender and group by age interaction effects. The significant effects were further investigated using follow-up univariate analysis of variance. The results showed significant main effects of Group, Gender and Age, and a significant Group by Gender interaction effect. The results showed no statistically significant differences in impulsivity between pathological gamblers and skydivers; however, both groups scored higher than the controls. The skydivers scored higher compared to the pathological gamblers and controls on both sensation seeking subscales. Pathological gamblers scored higher than the controls on the subscale Need for Stimulus Intensity, although lower than the controls on the subscale Need for Novelty. We conclude that skydivers and pathological gamblers do not seem to differ in terms of impulsivity, but that the two groups differ in terms of sensation seeking. Skydivers are hence characterized by more sensation seeking compared to pathological gamblers. Skydiving, as opposed to pathological gambling, is not considered a psychiatric disorder, and skydiving may represent a more non-pathological way to fulfill the need for stimulus intensity.     

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.     

Neurocognitive profiles of preterm infants randomly assigned to lower or higher hematocrit thresholds for transfusion

Objective: Preterm infants are frequently transfused with red blood cells based on standardized guidelines or clinical concerns that anemia taxes infants' physiological compensatory mechanisms and thereby threatens their health and well-being. The impact of various transfusion guidelines on long-term neurocognitive outcome is not known. The purpose of this study is to evaluate long-term neurocognitive outcome on children born prematurely and treated at birth with different transfusion guidelines.

Methods: Neurocognitive outcomes were examined at school age for 56 preterm infants randomly assigned to a liberal (n?=?33) or restrictive (n?=?23) transfusion strategy. Tests of intelligence, achievement, language, visual-spatial/motor, and memory skills were administered. Between-group differences were assessed.

Results: Those in the liberal transfusion group performed more poorly than those in the restrictive group on measures of associative verbal fluency, visual memory, and reading.

Conclusions: Findings highlight possible long-term neurodevelopmental consequences of maintaining higher hematocrit levels.     

Rorschach personality predictors of weight loss with behavior modification in obesity treatment

Weight loss outcome for 49 obese patients after 6 months treatment in a behavior modification program was related to Rorschach personality characteristics according to the Comprehensive System (Exner, 2003), also including the Rorschach Oral Dependency Scale (Bornstein, 1996; Masling & Rabie, 1967). Less weight loss was predicted by signs of perceptual and cognitive distortions indicated by the Schizophrenia Index. More weight loss was predicted by Food Contents, suggesting a food preoccupation and possibly a benign dependency orientation. Patients with a focus on food and dependent needs could benefit above all from the treatment program implying learning how to handle food and eating in a supportive setting, as evidenced by more weight loss. Distortions in perception and cognition could constitute more profound difficulties in weight reduction important to recognize in obesity treatment.     

The N400 component in parents of children with specific language impairment

Children with specific language impairment (SLI) often have a family history of language disorder. In this study, ERPs in response to a visual semantic priming task were recorded in parents of children with SLI. Despite equal performance, the ERPs displayed differences in language processing: larger N400 amplitudes indicated that the parents, especially the fathers, were less primed by the preceding context. Difference waveforms showed that the fathers of SLI children, contrary to controls, had less differentiated responses to congruent versus incongruent sentences. We propose that the N400 observations may be residual markers of past language deficiencies in the fathers. No differences in the N400 effect were found in the mothers of SLI children.     

Patterns of intellectual ability in children with verbal deficits

Patterns of intellectual ability were examined in 81 children with verbal deficits identified by a Low Verbal/High Performance WISC profile. The results of verbal and nonverbal tests of intellectual functioning were factor-analyzed, and three groups of children were defined based on patterns of factor scores. Group 1 consisted of children with a Specific Language Disability (SLD) but good Abstract Reasoning ability, while Group 2 included SLD children with good Sequencing-Memory skills. Group 3 children displayed a General Language Disability (GLD) with deficits in both abstract reasoning and sequencing memory. The intellectual patterns were related to cognitive interpretations and found to have educational implications, with Group 1 children reading adequately, Group 2 children showing somewhat poorer reading skills, and Group 3 children reading very poorly. These findings emphasize the importance of identifying subgroups of children with verbal deficits and demonstrate the feasibility of extracting relatively specific cognitive information from global measures of intelligence. The results question the appropriateness of applying traditional assumptions regarding cognitive organization derived from studies of normal children to atypical groups of children.     

Swedish University Students’ Opinion Regarding Information About Soft Markers

The aim of this study was to investigate the opinions of Swedish university students about information regarding soft markers, when observed at second trimester ultrasound screening. A cross-sectional survey, where 85 Swedish university students completed a study specific questionnaire containing eleven hypothetical scenarios, involving various parameters (disease/syndromes/malformations with different characteristics), and location of the markers. Almost all participants indicated that they would wish to be informed, prior to the ultrasound examination, about the assessment and significance of soft markers. However, the number of respondents who requested information about a potential actual finding was considerably less. Several participants wanted to be informed about detected markers associated to serious conditions but not when the marker indicated an increased risk for a treatable disease. Also, the specific location of the marker was of importance to the participants. The majority of respondents wished to be informed about the soft markers if they were observed in the heart or the brain of the foetus, compared to if they were located in the intestine or the skeleton. The students’ opinion, in this study, implicate the importance of pre-examination information to enable expectant parents to make informed choice regarding the second trimester ultrasound screening as well as on reciving information of actual findings.     

Event-related potential findings in healthy extremely pre-term (< week 29) children at age 10.

Ten healthy extremely pre-term (EPT) children, born before gestational week 29, were tested at age 10 using mismatch negativity (MMN) and a three-tone odd-ball task; the results were then compared to age-matched full-term controls. We found no difference in MMN. By contrast, EPT children had generally shorter N1 latencies and larger P2 amplitudes, possibly indicating a more stimulus-driven response mode. However, P300 parameters, indicative of controlled attention, were unaffected.     

Sexual Intent Perceptions: The Role of Perceiver Experience and the Real‐Person Reduction1

What factors influence the amount of sexual intention accorded to a person's behavior? A perceiver's gender and personal experiences, and the nature of the relationship with the perceived were investigated. Two findings emerged. First, perceiver sexual and dating experiences predicted perceptions in addition to and independent of perceiver gender, but only for a “self” target. Second, hypothetical targets were perceived more sexually relative to targets that represented real people. These findings extended previous research suggesting that features of targets and perceivers in addition to gender are predictive of sexual perceptions. These target features (e.g., “self” vs. other, “real” vs. hypothetical) have distinct influences on sexual perceptions, suggesting that the choice of a target in research studies should be considered carefully.
