Simple ears - flexible behavior: Information processing in the moth auditory pathway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03)
Abstract Lepidoptera evolved tympanic ears in response to echolocating bats. Comparative studies have shown that moth ears
evolved many times independently from chordotonal organs. With only 1 to 4 receptor cells, they are one of the simplest hearing
organs. The small number of receptors does not imply simplicity, neither in behavior nor in the neural circuit. Behaviorally, the
response to ...
Communicating public avalanche warnings – what works?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-20)
Like many other mountainous countries, Norway has experienced a rapid increase in both recreational winter activities and fatalities in avalanche terrain during the past few decades: during the decade 2008–2017, 64 recreational avalanche fatalities were recorded in Norway. This is a 106% increase from that of the previous decade. In 2013, Norway therefore launched the National Avalanche Warning ...
Discrepancies in the spiking threshold and frequency sensitivity of nocturnal moths explainable by biases in the canonical auditory stimulation method
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-11)
The auditory stimulation method used in experiments on moth A cell(s) is generally believed to be adequate to characterize the encoding of bat echolocation signals. The stimulation method hosts, though, several biases. Their compounded effects can explain a range of discrepancies between the reported electrophysiological recordings and significantly alter the current interpretation. To test the ...
Are psychotic experiences related to poorer reflective reasoning?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-12)
<p><i>Background</i>: Cognitive biases play an important role in the formation and maintenance of delusions. These biases are indicators of a weak reflective mind, or reduced engaging in reflective and deliberate reasoning. In three experiments, we tested whether a bias to accept non-sense statements as profound, treat metaphorical statements as literal, and suppress intuitive responses is related ...
Global cortical thinning in acute anorexia nervosa normalizes following long-term weight restoration
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-09-22)
<b>Background:</b> Anorexia nervosa (AN) is a serious eating disorder characterized by selfstarvation,
extreme weight loss and alterations in brain structure. Structural magnetic
resonance imaging (sMRI) studies have documented brain volume reductions in acute AN,
but it is unclear whether they are 1) regionally-specific or 2) reversible following weight
restoration. Here, we measured cortical ...
Analyzing buyer behavior when selecting green criteria in public procurement
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
Given the complexity of green public procurement, decisions are likely to be driven by bounded rationality. However, we know little about what determines supplier selection criteria in any given situation. This study explores buyer behavior when considering environmental criteria. We first conducted interviews and identified 12 operational procedures used by buyers. We then developed a survey to ...
Protocol for the Northern babies longitudinal study: predicting postpartum depression and improving parent–infant interaction with The Newborn Behavioral Observation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-27)
Postpartum depression (PPD) is a prevalent
disorder. Studying the factors related to PPD will help
to identify families at risk and provide preventive
interventions. This can in turn improve the developmental
trajectories for the children. Several previous studies
have investigated risk factors for PPD. However, few
studies have focused on cognitive vulnerability factors.
The first aim of the ...
Liberale akzeptanz als kognitiver mechanismus bei psychose: Eine 2-stufen-theorie der pathogenese schizophrener positivsymptome
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-30)
Positivsymptome wie Wahn und Halluzinationen stellen definierende Symptome
einer (schizophrenen) Psychose dar. In dieser Übersichtsarbeit wird
ein 2-stufiges heuristisches Modell für die Entstehung und Aufrechterhaltung
psychotischer Positivsymptome vorgelegt. Im Kern der Theorie steht
die Hypothese, dass von Psychose betroffene Menschen eine erniedrigte
Entscheidungsschwelle aufweisen, die zu ...
Optimizing the RMET to measure bias not performance differences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-22)
<p>Background: Human social interaction and communication is complex. Sending a verbal message is often accompanied by intonations, facial expressions, grimaces, and body postures. Nonverbal signals are potentially open for misinterpretation. One popular test for assessing the interpretation of facial expressions is the “Reading the Mind in the Eyes” Test (RMET). This test has been used to relate ...
Evaluation of a brief unguided psychological online intervention for depression: A controlled trial including exploratory moderator analyses
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-28)
<p><i>Background</i>:
Psychological online interventions (POIs) reduce depression but we know little about factors influencing their effectiveness. We evaluated a new, brief POI for depression and conducted exploratory moderator analyses.</p>
<p><i>Methods</i>:
In this online trial (German Clinical Trials Register; DRKS00011045), we allocated participants to treatment as usual (TAU; n = 67) or ...
