Play it again with feeling: computer feedback in musical communication of emotions

Communication of emotions is of crucial importance in music performance. Yet research has suggested that this skill is neglected in music education. This article presents and evaluates a computer program that automatically analyzes music performances and provides feedback to musicians in order to enhance their communication of emotions. Thirty-six semi-professional jazz /rock guitar players were randomly assigned to one of 3 conditions: (1) feedback from the computer program, (2) feedback from music teachers, and (3) repetition without feedback. Performance measures revealed the greatest improvement in communication accuracy for the computer program, but usability measures indicated that certain aspects of the program could be improved. Implications for music education are discussed.     

Interactive effects of APOE and CHRNA4 on attention and white matter volume in healthy middle-aged and older adults

In the present study, we investigated age-related changes in interactions between efficiency of neuronal repair mechanisms and efficiency of cholinergic neurotransmission in the context of attentional orienting. In addition, we explored white matter volume changes as possible neuronal underpinnings. A sample of 230 healthy middle-aged (53–64 years) and older (65–75 years) adults was genotyped for polymorphisms of APOE and CHRNA4, a nicotinic receptor subunit gene. Participants were administered a visuospatial attention task involving letter discrimination with location cues of varying validity. Genotype effects on white matter volume were also investigated in a subset of participants who received MRI scans. APOE interacted with CHRNA4, such that APOE-ε4 carriers who were also CHRNA4 TT homozygotes showed disproportionately slowed reaction time (RT) following invalid location cues. The interaction was stronger in the middle-aged participants than in the older participants. There was also a trend for individuals with combined APOE-ε4/CHRNA4 TT genotypes to show both lower white matter volume and slower overall RT on the attention task. The interaction of a neurotransmission gene (CHRNA4) and a susceptibility gene (APOE) suggests that the efficiency of neuronal repair mechanisms may modulate the cholinergic system to influence attentional function.     

Do Psychotherapists with Different Theoretical Orientations Stereotype or Prejudge Each Other?

This study investigates a possible threat to the progress of psychotherapy. It aims to detect and compare stereotyped or even prejudiced views among psychotherapists of different theoretical orientations, building on social psychological theory of in-groups and out-groups. Swedish psychotherapists (n = 416) of four different orientations (psychodynamic, cognitive, behavioural, or integrative/eclectic) used the valuable elements in psychotherapy questionnaire to rate the importance of various elements in psychotherapy. They also estimated how therapists of other orientations would rate these elements. These estimates were then compared with therapists’ actual self-ratings in order to detect patterns of stereotyping or prejudiced views. Psychotherapists exaggerate the differences between their own and other orientations in a stereotyped way, but correctly predict what members of their own orientation (in-group) find important. However, they overestimate how important ‘orientation-typical features’ are to those of other orientations (out-group), indicating a clear tendency to stereotype. Overall, integrative/eclectic therapists’ estimates were less stereotyped than the estimates of therapists of other orientations. A somewhat unexpected finding was that cognitive and behavioural therapists seem more inclined towards stereotyping. The stereotyped views of other theoretical orientations among psychotherapists can be argued to have negative connotations and may thus be seen as prejudices. These prejudices could create irrational and unnecessary obstacles to the development of both the science and the practice of psychotherapy and signal the need for psychotherapists of all orientations to develop a more balanced picture of each other.     

In God and CAM We Trust. Religious Faith and Use of Complementary and Alternative Medicine (CAM) in a Nationwide Cohort of Women Treated for Early Breast Cancer

Turning to faith in God or a higher spiritual power is a common way of coping with life-threatening disease such as cancer. Little, however, is known about religious faith among cancer patients in secular societies. The present study aimed at exploring the prevalence of religious faith among Danish breast cancer patients and at identifying whether socio-demographic, pre-cancer health status, clinical, and health behavior characteristics, including their use of complementary and alternative medicine (CAM), were associated with their degree of faith. Information on faith in God or a higher spiritual power and use of CAM was provided by a nationwide sample of 3,128 recurrence-free Danish women who had received surgery for early-stage breast cancer 15–16 months earlier. Socio-demographic, clinical, and health status variables were obtained from national longitudinal registries, and health behaviors had been assessed at 3–4 months post-surgery. Of the women, 47.3% reported a high degree of faith (unambiguous believers), 35.9% some degree of faith (ambiguous believers), while the remaining 16.8% were non-believers. Unambiguous believers were more likely than ambiguous believers to experience their faith as having a positive impact on their disease and their disease-related quality-of-life. When compared to non-believers, unambiguous believers were also older, had poorer physical function, and were more frequent users of CAM, and more inclined to believe that their use of CAM would have a beneficial influence on their cancer. Disease- and treatment-related variables were unrelated to faith. While overall religious faith appears equally prevalent among Danish and US breast cancer patients, the majority of Danish breast cancer patients experienced ambiguous faith, whereas the majority of US patients have been found to express unambiguous faith. Our results suggest that future studies may benefit from exploring the role of faith for health behaviors, adherence to conventional treatment, and impact upon quality of life.     

Influence of delayed muscle reflexes on spinal stability: Model-based predictions allow alternative interpretations of experimental data

Model-based calculations indicate that reflex delay and reflex gain are both important for spinal stability. Experimental results demonstrate that chronic low back pain is associated with delayed muscle reflex responses of trunk muscles. The aim of the present study was to analyze the influence of such time-delayed reflexes on the stability using a simple biomechanical model. Additionally, we compared the model-based predictions with experimental data from chronic low back pain patients and healthy controls using surface-electromyography. Linear stability methods were applied to the musculoskeletal model, which was extended with a time-delayed reflex model. Lateral external perturbations were simulated around equilibrium to investigate the effects of reflex delay and gain on the stability of the human lumbar spine. The model simulations predicted that increased reflex delays require a reduction of the reflex gain to avoid spinal instability. The experimental data support this dependence for the investigated abdominal muscles in chronic low back pain patients and healthy control subjects. Reflex time-delay and gain dependence showed that a delayed reflex latency could have relevant influence on spinal stability, if subjects do not adapt their reflex amplitudes. Based on the model and the experimental results, the relationship between muscle reflex response latency and the maximum of the reflex amplitude should be considered for evaluation of (patho) physiological data. We recommend that training procedures should focus on speeding up the delayed reflex response as well as on increasing the amplitude of these reflexes.     

What determines a feeling's position in affective space? A case for appraisal

The location of verbally reported feelings in a three-dimensional affective space is determined by the results of appraisal processes that elicit the respective states. One group of participants rated their evaluation of 59 pictures from the International Affective Picture System (IAPS) on a profile of nine appraisal criteria. Another group rated their affective reactions to the same pictures on the classic dimensions of affective meaning (valence, arousal, potency). The ratings on the affect dimensions correlate differentially with specific appraisal ratings. These results can be interpreted as showing that the reactions to the IAPS pictures are predictably produced through appraisal of picture content. The relevance of the findings for emotion induction paradigms and for emotion theory in general is discussed.     

The time course of resource allocation in spider-fearful participants during fear reactions

The dynamics of resource allocation to pictures of spiders and other animals in spider-fearful participants was investigated. The task of the participants was to respond rapidly and accurately to various probe stimuli superimposed on pictures of different animals. These were arguably fear relevant (spiders, snakes, and wolves) and fear irrelevant (beetles, turtles, and rabbits). The probes were shown with different stimulus onset asynchronies (SOAs) from picture onset to address the dynamics of resource allocation. A larger allocation of resources to spider pictures than to pictures of all other animals, with no difference between the latter regarding resource allocation was found. For the task that demanded more resources the fear-related physiological responses decreased, suggesting that controlled processing modulates fear responses.     

Intending or Pretending? Automatic Evaluations of Goal Cues Discriminate True and False Intentions

This research presents a novel approach to discriminating between true and deceptive statements about intended future behavior. Arguing that true intentions are goal‐directed, we predict that people who genuinely intend to pursue a reported goal will implicitly evaluate goal‐relevant cues positively, whereas people who do not intend to pursue the goal will not. Participants in an experiment were instructed to tell the truth about a planned future behavior (true intention) or to falsely report that same behavior to mask their actual mock‐criminal intention (false intention). As predicted, an evaluative priming task showed that participants with true intention exhibited implicit positive evaluations of cues relevant to the reported goal, whereas participants with false intention did not. Subsequent analyses showed that implicit positivity significantly discriminated between true and false intentions. The findings are discussed in terms of theoretical contributions and implications for the development of future detection tools. Copyright © 2012 John Wiley & Sons, Ltd.     

Expect the Unexpected? Variations in Question Type Elicit Cues to Deception in Joint Interviewer Contexts

We examined the effect of (i) a second interviewer's demeanour and (ii) asking expected and unexpected questions on cues to deception. We predicted that liars compared with truth tellers would provide more detail to expected questions and less detail to unexpected questions, particularly when the second interviewer is supportive. Liars prepare answers for expected questions, and a supportive interviewer will encourage them to provide more detail. By definition, liars have not prepared answers for unexpected questions, and their answers to such questions will be less detailed. Participants (N = 168) appeared before two interviewers: The first asked all the questions, and the second remained silent. The second interviewer exhibited either a supportive or a neutral demeanour. As predicted, liars provided more detail to expected questions and less detail to unexpected questions, particularly when the second interviewer was supportive. In conclusion, a supportive second interviewer elicits cues to deceit. Copyright © 2013 John Wiley & Sons, Ltd.     

Psychometric properties of the Norwegian version of the Childhood Trauma Questionnaire in high‐risk groups

The Childhood Trauma Questionnaire ‐ Short Form (CTQ‐SF) is widely used to measure childhood abuse of all types. In the present study, we examined the psychometric properties of the Norwegian version of the instrument. The participants constituted four subsamples (n = 517): substance abusers (n = 126), psychiatric patients (n = 210), prisoners (n = 109) and adolescents in out‐of‐home placements (n = 72). Confirmatory factor analysis revealed a reasonable fit of the data to the original five‐factor structure of the CTQ‐SF. Measurement invariance was found across gender and the four subsamples. It was concluded that the Norwegian version of the CTQ‐SF has acceptable psychometric properties, with good reliability and satisfactory accuracy, to assess different dimensions of childhood trauma.
