Depth distribution of oxygen vacancies in 1 MeV Li + -irradiated KTiOPO 4

Electron-energy-loss spectra have been recorded from cross-sectional transmission electron microscopy samples of Li + -irradiated KTiOPO 4 single crystals. By evaluating the intensity in the pre-edge shoulder of the OK ionization edge, the depth distribution of O vacancies in radiation-damaged KTiOPO 4 was monitored. Li + irradiation at 295K and Li + irradiation at 100K generate very similar defect profiles except for an additional superficial maximum in the room-temperature-irradiated sample. Vacancy distributions in the O sublattice can be monitored on the nanometre scale by the method introduced. The methodology is potentially applicable to a wide range of materials, when pertinent defect-sensitive features in electron-energy-loss spectra are evaluated, and its sensitivity is expected to become further improved with the availability of monochromated electron sources in transmission electron microscopes.     

Fatal violence – from trauma to offence: A case study in forensic psychotherapy and trauma therapy with a migrant patient

Abstract

That persons who are objects of violence and traumatisation become offenders themselves is a typical feature of ill-fated cycles of violence in countries torn by fierce political, ethnic, and religious conflicts. Some refugees and migrants with this background present a challenge to forensic psychotherapy when they continue such patterns of physical force and criminal behaviour in a host country like Germany, and are found to be either not responsible or of diminished responsibility for their criminal acts by reason of mental disorders or addictions. Their offences create a critical legal situation for them, since they are threatened with deportation. At the same time, their clinical condition is critical, for they were possibly subjected to traumatic experiences by authorities in their past; their cooperation in the treatment can seriously affect their legal status. Finding a way out of these complications has to take these special factors into account. Our paper focuses on the case study of a refugee from North Africa, illustrating a model of cooperation in forensic inpatient treatment, special trauma therapy (narrative exposure therapy), and expert testimony.     

Affective priming in the valent/neutral categorisation task is due to affective matching,not encoding facilitation: Reply to Spruyt

Spruyt obtained an affective congruency effect in a valent/neutral categorisation task, which contrasts with the absence of such an effect in the same task that was reported by Werner and Rothermund. The crucial difference between the two studies is that Spruyt presented only valent primes, whereas Werner and Rothermund presented equal amounts of valent and neutral primes and targets in their experiments. Removing the neutral primes introduces a confound of affective matches with the required response. Affective congruency effects in Spruyt's study can be explained straightforwardly in terms of such an affective matching strategy. To demonstrate the influence of matching strategies in the valent/neutral task without neutral primes, we conducted an experiment in which we induced an affective mismatching strategy. In support of our reasoning, this study revealed an affective incongruency effect in the valent/neutral categorisation task. We conclude that affective congruency as well as incongruency effects in the valent/neutral categorisation task reflect post-lexical affective (mis-)matching strategies rather than encoding facilitation.     

Assessing Emotion Regulation in Social Anxiety Disorder: The Emotion Regulation Interview

Social anxiety disorder (SAD) is thought to involve emotional hyper-reactivity and emotion dysregulation. However, the precise nature of the emotion dysregulation in SAD has not been well characterized. In the present study, the Emotion Regulation Interview (ERI) was developed to quantify the frequency and self-efficacy of five emotion regulation strategies specified by Gross’s (Review of General Psychology 2: 271–299, 1998) process model of emotion regulation. Forty-eight individuals with SAD and 33 healthy controls (HCs) were interviewed about responses during (a) a laboratory speech task and (b) two recent social anxiety-evoking situations. Individuals with SAD reported greater use of avoidance and expressive suppression than HCs, as well as lesser self-efficacy in implementing cognitive reappraisal and expressive suppression. These regulation deficits were not accounted for by differences in emotional reactivity. These findings highlight specific emotion regulation deficits in SAD, and support the idea that the Emotion Regulation Interview may be usefully applied to other clinical disorders.     

Contingency in Nature

Contingencies in Nature may be explained, but such explanations refer to other contingencies (pt. I). Is there a way to “explain away” all contingencies? The first physical theory of modern times, Newton’s theory of gravitation, was received in a way that leaves this question open (pt. II), while Kepler’s theory of cosmological harmony arrived at a positive solution (pt. III). However, later developments in science outdated Kepler’s approach (pt. IV).     

The control of stimulus-driven saccades is subject not to central, but to visual attention limitations

In three experiments, we investigated whether the control of reflexive saccades is subject to central attention limitations. In a dual-task procedure, Task 1 required either unspeeded reporting or ignoring of briefly presented masked stimuli, whereas Task 2 required a speeded saccade toward a visual target. The stimulus onset asynchrony (SOA) between the two tasks was varied. In Experiments 1 and 2, the Task 1 stimulus was one or three letters, and we asked how saccade target selection is influenced by the number of items. We found (1) longer saccade latencies at short than at long SOAs in the report condition, (2) a substantially larger latency increase for three letters than for one letter, and (3) a latency difference between SOAs in the ignore condition. Broadly, these results match the central interference theory. However, in Experiment 3, an auditory stimulus was used as the Task 1 stimulus, to test whether the interference effects in Experiments 1 and 2 were due to visual instead of central interference. Although there was a small saccade latency increase from short to long SOAs, this difference did not increase from the ignore to the report condition. To explain visual interference effects between letter encoding and stimulus-driven saccade control, we propose an extended theory of visual attention.     

EDMUND ENGELMAN: PHOTOGRAPHER OF SIGMUND FREUD'S HOME AND OFFICES

Over the course of several days in May 1938, Edmund Engelman, a young, talented and resourceful Viennese photographer, immortalised the home and offices of Sigmund Freud in a series of pictures that represent the fullest visual documentation of the setting in which Freud lived and worked throughout almost his entire career. He also photographed Freud, his daughter and his wife. These photographs are best known through a book that also contains a memoir of Engelman (Engelman, 1976). The photographs have been recognised primarily for their documentary value and not appreciated for their artistic merit. Through a series of interviews with Engelman and members of his family, biographical data about the artist and information about the photographs has been gathered that heretofore has not been published. This historical note elaborates on Engelman's life before and after taking the photographs, and places the photographs in the context of the life of the photographer.     

Moving arms: the effects of sensorimotor information on the problem-solving process

Embodied cognition postulates a bi-directional link between the human body and its cognitive functions. Whether this holds for higher cognitive functions such as problem solving is unknown. We predicted that arm movement manipulations performed by the participants could affect the problem-solving solutions. We tested this prediction in quantitative reasoning tasks that allowed two solutions to each problem (addition or subtraction). In two studies with healthy adults (N?=?53 and N?=?50), we found an effect of problem-congruent movements on problem solutions. Consistent with embodied cognition, sensorimotor information gained via right or left arm movements affects the solution in different types of problem-solving tasks.     

Motivation and self‐regulation: The role of want‐to motivation in the processes underlying self‐regulation and self‐control

Research on self‐regulation has largely focused on the idea of effortful self‐control, which assumes that exerting willpower will lead to greater success. However, in recent years, research has challenged this perspective and instead proposes that effortless self‐regulation is more adaptive for long‐term goal pursuit. Taking into consideration the burgeoning literature on effortless self‐regulation, here we propose that motivation—or the reasons why we pursue our goals—plays an integral role in this process. The objective of the present paper is to highlight how motivation can play a role in how self‐regulation unfolds. Specifically, we propose that pursuing goals because you want‐to (vs. have‐to) is associated with better goal attainment as a function of experiencing less temptations and obstacles. While the reason why want‐to motivation relates to experiencing fewer obstacles has yet to be thoroughly explored, here we propose some potential mechanisms drawing from recent research on self‐regulation. We also provide recommendations for future research, highlighting the importance of considering motivation in the study of self‐regulatory processes.
