Neurocognitive impairment in early adolescence following prenatal alcohol exposure of varying duration.

The aims of the study were, first, to perform a comprehensive assessment of neurocognitive status in early adolescence of children exposed to alcohol prenatally; and, second, to examine whether duration of exposure continues to be predictive of outcome at this age. Twenty-seven exposed 12-14-year-olds and 39 non-exposed 13-14-year-olds underwent neuropsychological assessments (WISC-III, NEPSY subtests) of attention and executive functions, language, visuomotor functions, and memory. The group of non-exposed children was used to develop preliminary test norms for the 13-14-year-old exposed children whereas published test norms could be used for the 12-year-olds. The results demonstrated neurocognitive impairment across all types of tasks. Impairment varied in degree according to the duration of alcohol exposure. Children exposed throughout pregnancy, most of who had diagnoses of Fetal Alcohol Syndrome (FAS) or Fetal Alcohol Effects (FAE), performed well below the average range. It was concluded that the neurocognitive effects of alcohol exposure tend to be widespread and generalized. Attention and executive functions do not seem to be selectively affected. Further, the relationship between duration of prenatal alcohol exposure and neurocognitive development continues to be significant in early adolescence.     

The Norwegian version of the five factor narcissism inventory for vulnerable narcissism and the grandiose narcissism subscale of indifference: Psychometric properties of the long‐ and short‐form versions

In recent years, narcissism has been reconceptualized as a multi‐dimensional feature of human psychology. The Five Factor Narcissism Inventory (FFNI) has been proposed as a measure for two distinguishable dimensions of narcissism: Vulnerable and Grandiose (Glover, Miller, Lynam, Crego & Widiger, 2012). To investigate the role that some of these factors may have in moderating responses to cues of social exclusion, implemented in a connected laboratory experiment, we translated the subscales for Vulnerable Narcissism and the Grandiose Narcissism subscale of Indifference from English into Norwegian and included them in an online survey that was used to recruit and pre‐screen participants for the laboratory experiment. In this paper, we test the psychometric properties of these translated self‐report measures, in what amounted to be a diverse sample of the Norwegian population. We perform reliability tests and confirmatory factor analysis on the long‐ and short‐form versions of FFNI Vulnerable Narcissism and the Grandiose Narcissism subscale of Indifference. We further test the criterion validity of these measures by way of correlational analyses with other theoretically relevant measures. We conclude that the Norwegian short‐form versions of FFNI Vulnerable Narcissism and Grandiose Narcissism subscale of Indifference exhibit good psychometric properties in our data and propose that the translated scales can now be used to explore these constructs in clinical and non‐clinical populations in Norway, and can be easily adapted for use in other Scandinavian countries.     

Grounding by Attention Simulation in Peripersonal Space: Pupils Dilate to Pinch Grip But Not Big Size Nominal Classifier

Grammatical categories represent implicit knowledge, and it is not known if such abstract linguistic knowledge can be continuously grounded in real‐life experiences, nor is it known what types of mental states can be simulated. A former study showed that attention bias in peripersonal space (PPS) affects reaction times in grammatical congruency judgments of nominal classifiers, suggesting that simulated semantics may include reenactment of attention. In this study, we contrasted a Chinese nominal classifier used with nouns denoting pinch grip objects with a classifier for nouns with big object referents in a pupil dilation experiment. Twenty Chinese native speakers read grammatical and ungrammatical classifier‐noun combinations and made grammaticality judgment while their pupillary responses were measured. It was found that their pupils dilated significantly more to the pinch grip classifier than to the big object classifier, indicating attention simulation in PPS. Pupil dilations were also significantly larger with congruent trials on the whole than in incongruent trials, but crucially, congruency and classifier semantics were independent of each other. No such effects were found in controls.     

The effect of dopaminergic medication on conflict adaptation in Parkinson's disease

Parkinson's disease (PD) is a neurological disorder associated primarily with motor symptoms such as tremor, slowness of movement, and difficulties with gait and balance. Most patients take dopaminergic medication to improve their motor functions. Previous studies reported indications that such medication can impair higher cognitive functions (cf. dopamine overdose hypothesis). In the present study, we examined the effect of medication status on conflict adaptation. PD patients performed a Stroop task in which we manipulated the proportion of congruent and incongruent items, thereby allowing us to explore conflict adaptation. The use of mouse movements allowed us to examine the action dynamics of conflict adaptation in PD, and their sensitivity to dopaminergic medication. Each patient performed the same task twice: once without making changes to their regular medication regime, and once after overnight withdrawal from their medication. Results showed that medication improved mouse movements and alleviated motor symptoms. Moreover, patients' mouse movements were modulated as a function of the proportion congruency manipulation, revealing conflict adaptation in PD, which was unaffected by medication status. The present study extends earlier work on conflict adaptation in PD where reduced transient (trial-by-trial) conflict adaptation was observed ON compared to OFF medication (Duthoo et al., 2013, Neuropsychology, 27, 556). Our findings suggest that more sustained cognitive control processes may not be sensitive to dopamine overdose effects.     

Negotiating ending: A qualitative study of the process of ending psychotherapy

Objectives: When psychotherapy is open-ended, the question of termination is a matter for negotiation. A model based on both content and the process of ending may explain how ‘good enough’ psychotherapies can be brought to ‘good enough’ endings.

Design: Twelve processes of ending were explored through a combination of audio recordings made during therapy sessions and post-therapy interviews with clients and therapists. Therapies had been tailored to the needs of the clients and were based on a broad spectrum of theoretical affiliations.

Methods: A procedure for systematic text condensation was used on a case-by-case basis. Issues surrounding the initiation and negotiation of ending were pointed out in each case and were then compared across cases.

Results: The initiation of ending and exchanges concerned with when and how to end therapy unfolded as a concerted process because both parties seemed to be aware that the theme of ending contained a potential challenge to the alliance. Dual affect regulation, implicit communication and a future-oriented perspective were important features. Structural elements such as schedule changes and temporary breaks served several psychological functions. Therapies seemed to reach ‘good enough’ endings when the client and therapist joined in their efforts to resolve basic ambivalences embedded in the decision to terminate contact with the affirmation of a continuing emotional bond.     

The influence of word shading and word length on eye movements during reading

In three experiments rats were given short or long preexposure (4 or 10 sessions) to two compound flavours, AX and BX, according to an intermixed or a blocked schedule. Following preexposure, aversion conditioning trials were given with AX as the conditioned stimulus (CS). In Experiments 1 and 2, retardation and summation tests were then carried out to assess the inhibitory properties of B (an Espinet procedure). In Experiment 3, test trials evaluated generalization from AX to BX (the standard perceptual learning procedure). The results showed that B performed as an inhibitor of the unconditioned stimulus (US; an Espinet effect) only after long intermixed preexposure, whereas a reliable perceptual learning effect was observed both after short and after long preeexposure. The observation that B had no detectable inhibitory properties after short preexposure casts doubt on the suggestion that inhibitory learning is responsible for perceptual learning after brief exposure to AX and BX.     

Linguistic and nonlinguistic influences on the eyes' landing positions during reading

Two eye tracking experiments show that, for near launch sites, the eyes land nearer to the beginning of words with orthographically irregular than with regular initial letter sequences. In addition, the characteristics of words, at least at the level of orthography, influence the direction and length of within-word saccades. Importantly, these effects hold both for lower case and for visually less distinctive upper case text. Furthermore, contrary to previous evidence (Tinker & Paterson, 1939), there is little effect of type case on reading times. Additional analyses of oculomotor behaviour suggest that there is an inverted optimal viewing position for single fixation durations on words. Both the supplementary analyses and the effects of orthography on fixation positions are relevant to current models of eye movements in reading.     

Giant magnetoelectric effect in laminate composites

It has been found that laminate composites of longitudinally magnetized magnetostrictive and transversely poled piezoelectric layers (an L–T laminate composite) have a giant magnetoelectric (ME) effect. Relatively high ME coupling, that is significant exchange between magnetization and polarization, is demonstrated.     

Near-infrared transitions of LiNdP4O12 and LiErYP4O12

Abstract

Fluorescence transitions in LiNdP₄O₁₂: ⁴ F_3/2→⁴I_9/2 (0·90μm), ⁴F_3/2→⁴I_11/2 (1·05μm), ⁴F_3/2→⁴I_13/2 (1·32μm), ⁴F_3/2→⁴I_15/2 (1·77μm), and in LiErYP₄O₁₂: ⁴S_3/2→⁴I_11/2 (1·3μm), ⁴I_13/2→⁴I_15/2 (1·53μm), have been obtained at room temperature. The positions of the energy levels related to the excitation, nonradiative and radiative processes have been established from complementary absorption measurements. The fluorescence lifetimes of the above-mentioned transitions have been determined from single exponential decays.
