Abstract Controllability over stressors has major impacts on brain and behavior. In humans, however, the effect of controllability responses to is poorly understood. Using functional magnetic resonance imaging (fMRI), we investigated how altered a shock-plus-sound stressor with between-group yoked design, where participants in controllable uncontrollable groups experienced matched exposure. Employing Bayesian multilevel analysis at level regions interest voxels insula, standard voxelwise...
Locus of control (LOC) beliefs, long thought important in adjustment to persistent pain, were studied among 160 subjects (67 males and 93 females) referred a comprehensive pain rehabilitation program. The subscale structure the Multidimensional Health Control (MHLC) was factorially replicated our sample. Three unique MHLC profile clusters identified for both females. Among men, cluster assignment related age only. younger male patients reported stronger internal attributional style. Older...
Abstract Over the past three decades, functional magnetic resonance imaging (fMRI) has become crucial to study how cognitive processes are implemented in human brain. However, question of whether participants recruited into fMRI studies differ from other contexts received little no attention. This is particularly pertinent when effects fail generalize across contexts: for example, a behavioural effect discovered non-imaging context not replicating neuroimaging environment. Here, we tested...
One in every 6 couples is infertile, and the literature suggests that a number of individuals experience psychological distress associated with infertility. The purpose this study was to investigate predictors among infertility clinic patients. Analyses indicated infertile men (n = 86) women 120) reported greater than normative data from general population. Separate hierarchical multiple regressions revealed self-blame avoidance coping best predictor women. Increased age not already having...
Counselors' vulnerability to inferential bias during the counseling process may result in misdiagnosis and improper interventions. This article provides readers with information regarding bias. The biases discussed include (a) availability representativeness heuristics; (b) fundamental attribution error; (c) anchoring, prior knowledge, labeling; (d) confirmatory hypothesis testing; (e) reconstructive memory. Each is described illustrated through fictitious case vignettes, suggestions...
Abstract In the present fMRI study, we examined how anxious apprehension is processed in human brain. A central goal of study was to test prediction that a subset brain regions would exhibit sustained response profiles during threat periods, including anterior insula, region implicated anxiety disorders. second important evaluate responses amygdala and bed nucleus stria terminals, have been suggested be involved more transient threat, respectively. total 109 participants performed an...
The aim of this current study is to determine whether the neck a viable location receive tactile directional information substitute vestibular loss. While wearing vibrotactile device with 14 motors equally positioned around neck, participants were asked detect exact delivered stimulus delivered. results show that front may not be as sensitive remaining areas, and frequency duration stimulation do significantly impact performance. Although could accurately identify points stimulation, they...
The human amygdala consciously and nonconsciously processes facial expressions directs spatial attention to them. Research has shown that activity habituates after repeated exposure emotionally salient stimuli during passive viewing tasks. However, it is unclear what extent the biologically relevant amygdala-mediated behaviors, such as orienting of environmentally social signals. present study investigated habituation a dot-probe task measuring attentional bias backward masked fearful faces....
Over the past three decades, functional MRI (fMRI) has become key to study how cognitive processes are implemented in human brain. However, question of whether participants recruited into fMRI studies differ from other contexts received little no attention. This is particularly pertinent when effects fail generalize across contexts: for example, a behavioural effect discovered non-imaging context not replicating neuroimaging environment. Here, we tested hypothesis, motivated by preliminary...
How sensitive is the neck in distinguishing two points of contact? The current study was performed to gain insight about spatial acuity hopes using this information future research and development tactile devices targeting area body. Using a two-point orientation discrimination task, relatively novel measure sensitivity, threshold eight locations around circumference measured. Results showed uniform sensitivity seven locations, with slightly lower at very front neck. These results indicate...
Abstract Controllability over stressors has major impacts on brain and behavior. In humans, however, the effect of controllability responses to themselves is poorly understood. Using functional magnetic resonance imaging, we investigated how altered a shock-plus-sound stressor. between-group yoked design, participants in controlled uncontrolled groups experienced same amount stressor exposure. Employing both Bayesian multilevel analysis targeting regions interest standard voxelwise analysis,...
The study investigated differences between rural and urban gifted high school students on two measures of locus control (LOC), the Intellectual Achievement Responsibility Questionnaire (IAR) Children's Nowicki‐Strickland Internal‐External scale (CNSIE). Results indicated that tend to claim more responsibility for negative events in academic domain (e.g., lower grade than was expected) students. Implications results are noted.
Sustained anticipation of unpredictable aversive events generates anticipatory processing that is central to anxiety. In the present functional Magnetic Resonance Study (fMRI) study, we examined how sustained threat processed in human brain. We used a relatively large sample ( N = 109) and employed Bayesian multilevel analysis approach contrast safe periods. Our analyses demonstrated effect heterogeneous distributed across Thus, impact widespread, not restricted small set putatively...
