Too Many Fish in the Sea: A Motivational Examination of the Choice Overload Experience
Evidence supports that being overwhelmed by many choice options predicts negative consequences. However, there is uncertainty regarding the effects of choice overload on two key motivational dimensions: (1) the extent to which people view their decision as subjectively valuable (versus not), and (2) the extent to which people view themselves as capable (versus incapable) of reaching a good decision. While evaluating their options and while deciding, we assessed theory-based cardiovascular responses reflecting these dimensions. A meta-analysis across two experiments found that participants who made a final selection from many options—relative to those who chose from few or rated many—exhibited cardiovascular responses consistent with greater task engagement (i.e., perceiving greater subjective value), as well as greater threat (i.e., perceiving fewer resources to manage situational demands). The current work suggests a novel motivational account of choice overload, providing insight into the nature and timing of this experience as it occurs
When a small self means manageable obstacles: Spontaneous self-distancing predicts divergent effects of awe during a subsequent performance stressor
The emotion of awe occurs when one feels small relative to something vaster than the self; it leads to benefits such as care for others. However, because awe elicits the experience of a “small self,” it is unclear to what extent awe positively versus negatively affects responses to subsequent stressors. If personal obstacles seem trivial in comparison to awe-inspiring stimuli, stressors should seem either manageable or unimportant, but if one's capabilities seem comparatively insignificant, stressors should seem unmanageable. We hypothesized that awe would have a generally positive effect on responses during a subsequent performance stressor, but that this would further depend on whether people tended to spontaneously take on a self-distanced versus self-immersed perspective. In the face of awe, focusing less on the self (self-distanced perspective) should make obstacles in particular seem trivial, whereas focusing more on the self (self-immersed) should lead one's capabilities to seem insignificant. Using the biopsychosocial model of challenge/threat, we found that spontaneous self-distancing significantly moderated awe's effects on responses during a subsequent performance stressor (speech task): For participants who self-distanced, the awe condition led to cardiovascular responses consistent with greater challenge than the neutral control condition (reflecting evaluating the stressor as more manageable); for participants who self-immersed, awe predicted relative threat (less manageable stressor). There was no support for awe making people care less about the stressor (as reflected in cardiovascular responses consistent with task engagement). This offers insight into how awe can have divergent effects on people's experiences during performance stressors
In defense of commitment: The curative power of violated expectations in relationships.
A new model of commitment defense in romantic relationships is proposed. It assumes that relationships afford a central resource for affirming meaning and purpose in the world. Consequently, violating expectations about the world outside the relationship can precipitate commitment defense inside the relationship. A meta-analysis of 5 experiments, 2 follow-up correlational studies, and a longitudinal study of the transition to first parenthood supported the model. Experimentally violating conventional expectations about the world (e.g., “hard work pays off”) motivated less satisfied people to defensively affirm their commitment. Similarly, when becoming a parent naturalistically violated culturally conditioned gendered expectations about the division of household labor, less satisfied new mothers and fathers defensively affirmed their commitment from pre-to-post baby. The findings suggest that violating expected associations in the world outside the relationship motivates vulnerable people to set relationship their relationship right, thereby affirming expected associations in the relationship in the face of an unexpected world
Measuring Resilience in Adult Women Using the 10-Items Connor-Davidson Resilience Scale (CD-RISC). Role of Trauma Exposure and Anxiety Disorders
International audiencePURPOSE: Resilience is the ability of individuals to adapt positively in the face of trauma. Little is known, however, about lifetime factors affecting resilience. METHODS: We assessed the effects of psychiatric disorder and lifetime trauma history on the resilience self-evaluation using the Connor-Davidson Resilience Scale (CD-RISC-10) in a high-risk-women sample. Two hundred and thirty eight community-dwelling women, including 122 participants in a study of breast cancer survivors and 116 participants without previous history of cancer completed the CD-RISC-10. Lifetime psychiatric symptoms were assessed retrospectively using two standardized psychiatric examinations (Mini International Neuropsychiatric Interview and Watson's Post-Traumatic Stress Disorder Inventory). RESULTS: Multivariate logistic regression adjusted for age, education, trauma history, cancer, current psychiatric diagnoses, and psychoactive treatment indicated a negative association between current psychiatric disorder and high resilience compared to low resilience level (OR = 0.44, 95% CI [0.21-0.93]). This was related to anxiety and not mood disorder. A positive and independent association with a trauma history was also observed (OR = 3.18, 95% CI [1.44-7.01]). CONCLUSION: Self-evaluation of resilience is influenced by both current anxiety disorder and trauma history. The independent positive association between resilience and trauma exposure may indicate a "vaccination" effect. This finding need to be taken into account in future studies evaluating resilience in general or clinical populations
Resting-State Brain Activity in Adult Males Who Stutter
Although developmental stuttering has been extensively studied with structural and task-based functional magnetic resonance imaging (fMRI), few studies have focused on resting-state brain activity in this disorder. We investigated resting-state brain activity of stuttering subjects by analyzing the amplitude of low-frequency fluctuation (ALFF), region of interest (ROI)-based functional connectivity (FC) and independent component analysis (ICA)-based FC. Forty-four adult males with developmental stuttering and 46 age-matched fluent male controls were scanned using resting-state fMRI. ALFF, ROI-based FCs and ICA-based FCs were compared between male stuttering subjects and fluent controls in a voxel-wise manner. Compared with fluent controls, stuttering subjects showed increased ALFF in left brain areas related to speech motor and auditory functions and bilateral prefrontal cortices related to cognitive control. However, stuttering subjects showed decreased ALFF in the left posterior language reception area and bilateral non-speech motor areas. ROI-based FC analysis revealed decreased FC between the posterior language area involved in the perception and decoding of sensory information and anterior brain area involved in the initiation of speech motor function, as well as increased FC within anterior or posterior speech- and language-associated areas and between the prefrontal areas and default-mode network (DMN) in stuttering subjects. ICA showed that stuttering subjects had decreased FC in the DMN and increased FC in the sensorimotor network. Our findings support the concept that stuttering subjects have deficits in multiple functional systems (motor, language, auditory and DMN) and in the connections between them
Regulation of BRCA1 expression and its relationship to sporadic breast cancer
Germ-line mutations in the BRCA1 tumour suppressor gene contribute to familial breast tumour formation, but there is no evidence for direct mutation of the BRCA1 gene in the sporadic form of the disease. In contrast, decreased expression of the BRCA1 gene has been shown to be common in sporadic tumours, and the magnitude of the decrease correlates with disease progression. BRCA1 expression is also tightly regulated during normal breast development. Determining how these developmental regulators of BRCA1 expression are co-opted during breast tumourigenesis could lead to a better understanding of sporadic breast cancer aetiology and the generation of novel therapeutic strategies aimed at preventing sporadic breast tumour progression
