Prereading skills of very-low-birth-weight prematurely born Finnish children

Our objective was to study the prereading skills of very-low-birth-weight (VLBW; ≤ 1500 g) prematurely born children at the age of five years. A regional cohort of 89 VLBW children and 152 full-term (FT) born children was assessed for letter knowledge, phonological processing, and speeded naming. Full-scale IQ (FSIQ) was assessed using a short version of WPPSI-R. The associations of parental and neonatal factors, and FSIQ with prereading skills were assessed. VLBW group had poorer prereading skills, and there were more VLBW children at-risk (performing < ?1 SD) compared to FT children in phonological processing (23% vs. 9%, p = .002), letter knowledge (27% vs. 14%, p = .017), and the accuracy of speeded naming (26% vs. 13%, p = .020). VLBW children had lower average FSIQ and Performance IQ (both comparisons p < .001) than FT controls, but Verbal IQ did not differ. When FSIQ was used as a covariate, VLBW children did not differ from the FT group in prereading skills indicating that they are at risk for more global developmental problems. Lower parental level of education as well as parent's reading problems were negatively associated with VLBW children's prereading skills. Positively, about 75% of VLBW children performed within the normal range in each individual prereading skill.     

The Art of Dying as an Art of Living: Historical Contemplations on the Paradoxes of Suicide and the Possibilities of Reflexive Suicide Prevention

The main aim of this paper is to reconstruct different aspects of the history of ideas of suicide, from antiquity to late modernity, and contemplate their dialectical tension. Reflexive suicide prevention, drawing on the ancient wisdom that the art of living is inseparable from the art of dying, takes advantage, it is argued, of the contradictory nature of suicide, and hence embraces, rather than trying to overcome, death, pain, grief, fear, hopelessness and milder depressions. This approach might facilitate the transformation of inner shame to inter-personal guilt, which is the precondition for coping with losses through grieving that is shared with others. The traditional projection of suicide on the ‘Other’, reinforced by modernity’s bio-political suppression of death, has inhibited development of good suicide prevention. Awareness of the ambiguity and ambivalence found in suicide may work as a resource when measures are taken to address as many causal mechanisms as possible, and bringing special emphasis to external factors.     

Measuring and testing awareness of emotional face expressions

Comparison of behavioural measures of consciousness has attracted much attention recently. In a recent article, Szczepanowski et al. conclude that confidence ratings (CR) predict accuracy better than both the perceptual awareness scale (PAS) and post-decision wagering (PDW) when using stimuli with emotional content (fearful vs. neutral faces). Although we find the study interesting, we disagree with the conclusion that CR is superior to PAS because of two methodological issues. First, the conclusion is not based on a formal test. We performed this test and found no evidence that CR predicted accuracy better than PAS (p = .4). Second, Szczepanowski et al. used the present version of PAS in a manner somewhat different from how it was originally intended, and the participants may not have been adequately instructed. We end our commentary with a set of recommendations for future studies using PAS.     

Measuring consciousness: task accuracy and awareness as sigmoid functions of stimulus duration

When consciousness is examined using subjective ratings, the extent to which processing is conscious or unconscious is often estimated by calculating task performance at the subjective threshold or by calculating the correlation between accuracy and awareness. However, both these methods have certain limitations. In the present article, we propose describing task accuracy and awareness as functions of stimulus intensity (thus obtaining an accuracy and an awareness curve) as suggested by Koch and Preuschoff (2007). The estimated lag between the curves describes how much stimulus intensity must increase for awareness to change proportionally as much as accuracy and the slopes of the curves are used to assess how fast accuracy and awareness increases and whether awareness is dichotomous. The method is successfully employed to assess consciousness characteristics on data from four different awareness scales.     

Personality in DSM-5: helping delineate personality disorder content and framing the metastructure

The transition from the Diagnostic and Statistical Model of Mental Disorders (4th ed., text revision [DSM-IV-TR]; American Psychiatric Association, 2000 ) to the fifth edition (DSM-5) represents an unprecedented opportunity to integrate dimensional personality trait models into the official nosology. Not surprisingly, a variety of issues have arisen in contemplating this challenging integration. In this article, we address how a dimensional personality trait model could be a helpful component of DSM-5, from the perspective of our roles as work group members and advisors involved in the creation of a trait model and corresponding assessment instrument. We focus in particular on two potential roles for a trait model in DSM-5 that are under official consideration. First, a dimensional personality trait model might be helpful in delineating the content of personality disorders. Second, a trait model might assist in organizing the "metastructure" of DSM-5 (i.e., the arrangement of chapters and other broader classificatory rubrics).     

Understanding Psychopathology: Melding Behavior Genetics, Personality, and Quantitative Psychology to Develop an Empirically Based Model

ABSTRACT— Research on psychopathology is at a historical crossroads. New technologies offer the promise of lasting advances in our understanding of the causes of human psychological suffering. Making the best use of these technologies, however, requires an empirically accurate model of psychopathology. Much current research is framed by the model of psychopathology portrayed in current versions of the Diagnostic and Statistical Manual of Mental Disorders ( DSM ; American Psychiatric Association, 2000 ). Although the modern DSM s have been fundamental in advancing psychopathology research, recent research also challenges some assumptions made in the DSM —for example, the assumption that all forms of psychopathology are well conceived of as discrete categories. Psychological science has a critical role to play in working through the implications of this research and the challenges it presents. In particular, behavior-genetic, personality, and quantitative-psychological research perspectives can be melded to inform the development of an empirically based model of psychopathology that would constitute an evolution of the DSM .     

The principle of liberty and legal representation of posterity

This paper considers a guardianship model for the legal representation of future generations. According to this model, national and international courts should be given the competence to appoint guardians for future generations, if agents who care about the welfare of posterity apply for the creation of a guardianship in relation to a dispute that can be resolved by the application of law. This reform would grant guardians of future people legal standing or locus standi before courts, that is, the right to bring an action before a court of law for adjudication. Although the guardianship model faces several difficult theoretical and practical problems pertaining to the representation of different near and distant future generations, it is argued that this model – and certain other legal norms intended to protect future basic needs – can be justified on the basis of the principle of liberty.     

Eye movements during repeated reading of a text

The facilitation of eye movements was studied in two experiments involving a repeated reading paradigm. A text was read three times. Initial reading was immediately followed by the first repetition; the second repetition took place one week later. Recall task instructions were used to encourage a detailed reading of the text. The data were analysed sentence by sentence from the 'first pass' readings not including returns to earlier test locations. A general facilitation for all eye movement parameters was found. Repetition decreased the summed fixation time, the average fixation duration, the number of progressive fixations, and the number of regressions. Additionally, repetition increased saccade lengths. Experiment 2 further qualified the general facilitory effect. The middle section of the text, being the most dense of information, was devoted the most visual attention by the readers. Moreover, it was also found to produce the largest degree of facilitation due to repetition. This was true with all other eye movement parameters except saccade length and average fixation duration. Average fixation durations were longer in the beginning of a text than in the end. This was true in all the three readings. Similarly, for each reading, highly important sentences received more visual attention than unimportant sentences.
