Trends in timing of sleep in the general population of Norway: 1980 to 20001

The aim of the current study was to examine whether the timing of sleep have changed over the last two decades. As part of a general survey of activities throughout the 24-hr. cycle, collected in 1980, 1990, and 2000 by Statistics Norway, information on sleep timing was obtained for every 15-min. interval for 1 wk. All three samples were representative of Norwegians. The age span was from 16 to 74 years. Timing of sleep was significantly delayed in 2000 compared to 1990 and especially so in 1980, but with no change in total amount of sleep. From 1980 to 2000, there was an increasing discrepancy in sleep or wake timing between weekdays and weekends. The current analyses show that people sleep as much as before but do so at different times. The increased discrepancy between weekdays and weekends indicates that overall sleep habits are poorer now than previously.     

A self-help book is better than sleep hygiene advice for insomnia: a randomized controlled comparative study

The objective was to compare the effects of two types of written material for insomnia in a randomized trial with follow-up after three months. Insomniacs were recruited through newspaper advertisements to a web-based survey with validated questionnaires about sleep, anxiety, depression, and use of sleep medications. A self-help book focusing on cognitive behavioral therapy for insomnia was compared to standard sleep hygiene advice; 77 and 78 participants were randomized to self-help book or sleep hygiene advice, respectively. The response rate was 81.9%. The self-help book gave significantly better scores on the sleep questionnaires compared to sleep hygiene advice. The proportion using sleep medications was reduced in the self-help book group, whereas it was increased in the sleep hygiene group. Compared to pre-treatment, the self-help book improved scores on the sleep (effect sizes 0.61-0.62) and depression (effect size 0.18) scales, whereas the sleep hygiene advice improved scores on some sleep scales (effect sizes 0.24-0.28), but worsened another (effect size -0.36). In addition, sleep hygiene advice increased the number of days per week where they took sleep medications (effect size -0.50). To conclude, in this randomized controlled trial, the self-help book improved sleep and reduced the proportion using sleep medications compared to sleep hygiene advice. The self-help book is an efficient low-threshold intervention, which is cheap and easily available for patients suffering from insomnia. Sleep hygiene advice also improved sleep at follow-up, but increased sleep medication use. Thus, caution is warranted when sleep hygiene advice are given as a single treatment.     

Human newborns match tongue protrusion of disembodied human and robotic mouths

No evidence had been provided so far of newborns’ capacity to give a matching response to 2D stimuli. We report evidence from 18 newborns who were presented with three types of stimuli on a 2D screen. The stimuli were video-recorded displays of tongue protrusion shown by: (a) a human face, (b) a human tongue from a disembodied mouth, and (c) an artificial tongue from a robotic mouth. Compared to a baseline condition, neonates increased significantly their tongue protrusion when seeing disembodied human and artificial tongue movements, but not when seeing a 2D full-face protruding tongue. This result was interpreted as revealing the exploration of top-heavy patterns of the 2D face that distracted infants’ attention from the tongue. Results also showed progressively more accurate matching (full tongue protrusion) throughout repeated exposure to each kind of stimulus. Such findings are not in line with the predictions of the innate releasing mechanism (IRM) model or of the oral exploration hypothesis. They support the active intermodal mapping (AIM) hypothesis that emphasizes not only the importance of repeated experience, as would the associative sequence learning (ASL) hypothesis, but also predicts a differential learning and progressive correction of the response adapted to each stimulus.     

Predicting proactive behaviour at work: Exploring the role of personality as an antecedent of whistleblowing behaviour

This paper reports on the role of personality as an antecedent of proactive behaviour at work in the form of whistleblowing. In the interest of triangulation, two studies were used, along with two personality measures. The results of Study 1, conducted among 503 municipality employees, show that the NEO Five‐Factor Inventory dimensions of extraversion and agreeableness are significantly associated with whistleblowing, with odds ratios of 1.13 and 0.91, respectively. The result from Study 2, conducted among a representative sample of employees, shows that the circumplex of interpersonal problems dimension domineering was significantly associated with whistleblowing, with an odds ratio of 1.66. The results suggest that personality, in the form of high extraversion and dominance and low agreeableness, do play a role as antecedents of whistleblowing.     

Adolescent Focused Psychotherapy for Adolescents with Anorexia Nervosa

The paper describes a manualized specific form on individually based developmentally oriented therapy for Anorexia Nervosa (AN) in adolescents. Adolescent focused psychotherapy for AN is derived from a self-psychology model and is designed to address key deficits in development associated with AN. Adolescents with AN are viewed as using food and weight to avoid negative affective states associated with adolescent developmental issues that they perceive as intolerable. To develop a more constructive coping style and improve self-efficacy, adolescent patients need to first learn to identify and define their emotions, and later, to tolerate emotions, particularly negative ones. In withdrawing from the environment and situations which provoke distress through self-starvation and preoccupations with food and weight, emotional and psychological development is arrested. Learning to identify and cope adaptively with emotions and developmental challenges presented by the environment form the key therapeutic targets of treatment. Specific therapeutic procedures, a case illustration and discussion of therapeutic rationale are also provided.     

Confronting Ideals of Proof with the Ways of Proving of the Research Mathematician

In this paper, we discuss the prevailing view amongst philosophers and many mathematicians concerning mathematical proof. Following Cellucci, we call the prevailing view the “axiomatic conception” of proof. The conception includes the ideas that: a proof is finite, it proceeds from axioms and it is the final word on the matter of the conclusion. This received view can be traced back to Frege, Hilbert and Gentzen, amongst others, and is prevalent in both mathematical text books and logic text books.     

CAMP: A community‐based approach to promoting safe sex behaviour in adolescence

The primary goal of this study was to describe the development and assessment of the Community Awareness Motivation Partnership (CAMP) Teen Theatre intervention. Based on the behavioural ecological model, CAMP addressed the role of contraceptive use in safe sex behaviour through a brief informative, entertaining, and culturally responsive dramatization programme. Adolescents (N = 1613) between the ages of 11 and 18 (M = 13.31, SD = 0.76) received the intervention, and 961 participants completed both pre‐ and post‐tests. The majority of participants were Latino (78.5%, n = 1039), many of whom were first generation immigrants. Results indicated that the intervention increased participants' reported intentions to delay sex and use contraceptives. The intervention produced short‐term changes in safe‐sex behavioural intentions and knowledge. Suggestions for producing long‐term changes were discussed.

From deed to word: gapless and kink-free enactivism

In their most recent book, Evolving Enactivism: Basic Minds Meet Content (MIT 2017), Dan Hutto and Eric Myin claim to give a complete and gapless naturalistic account of cognition, but it comes with a kink. The kink being that content-involving cognition has special properties found nowhere else in nature, making it the case that minds capable of contentful thought differ in kind, in this key respect, from more basic minds. Contra Hutto and Myin, I argue that content-involving practices are themselves simply a further extension of action and do not therefore warrant being called ‘different in kind’ or ‘kinky’. With the help of Ludwig Wittgenstein and John V. Canfield, I show that Enactivism meets the challenge of explaining higher-level cognition; and, contra continuity sceptics, offer ‘a philosophically cogent and empirically respectable account’ of how human minds can emerge from nonhuman minds.

     

Bright light treatment has limited effect in subjects over 55 years with mild early morning awakening

31 subjects, age 55 yr. or older, suffering from mild early morning awakening were randomized to either a bright light (10,000 lux) or to a red dim light placebo condition (200 lux). Light exposure took place in the evening in the patients' homes, 60 to 30 min. before bedtime and lasted for 3 wk. The subjects kept a sleep diary for 2 wk. and wore an actigraph for 1 wk. both before treatment and at post-treatment. Of the eight sleep diary outcome variables, significant effects that could be attributed to the light treatment were only detected for time spent in bed after final morning awakening. None of the six actigraph outcome variables yielded any significant effect of the light therapy. Explanations for the limited therapeutic effects of bright light treatment obtained in the present study are discussed, such as the criteria defining early morning awakening, the selection procedure, problems with compliance, age of the sample, and the dose of light. The lack of an objective circadian marker in this study could represent a problem concerning the timing of the light exposure. Despite the limited success of bright light therapy in this study, bright light therapy should still be considered as a treatment option for early morning awakening.
