Advances in theory and research on self‐regulation and decision‐making processes have yielded important insights into how cognitive, emotional, and social processes shape risk perceptions and risk‐related decisions. We examine how self‐regulation theory can be applied to inform our understanding of decision‐making processes within the context of genomic testing, a clinical arena in which individuals face complex risk information and potentially life‐altering decisions. After presenting key principles of self‐regulation, we present a genomic testing case example to illustrate how principles related to risk representations, approach and avoidance motivations, emotion regulation, defensive responses, temporal construals, and capacities such as numeric abilities can shape decisions and psychological responses during the genomic testing process. We conclude with implications for using self‐regulation theory to advance science within genomic testing and opportunities for how this research can inform further developments in self‐regulation theory.  相似文献

One of the fundamental challenges of visual cognition is how our visual systems combine information about an object’s features with its spatial location. A recent phenomenon related to object–location binding, the “spatial congruency bias,” revealed that two objects are more likely to be perceived as having the same identity or features if they appear in the same spatial location, versus if the second object appears in a different location. The spatial congruency bias suggests that irrelevant location information is automatically encoded with and bound to other object properties, biasing perceptual judgments. Here we further explored this new phenomenon and its role in object–location binding by asking what happens when an object moves to a new location: Is the spatial congruency bias sensitive to spatiotemporal contiguity cues, or does it remain linked to the original object location? Across four experiments, we found that the spatial congruency bias remained strongly linked to the original object location. However, under certain circumstances—for instance, when the first object paused and remained visible for a brief time after the movement—the congruency bias was found at both the original location and the updated location. These data suggest that the spatial congruency bias is based more on low-level visual information than on spatiotemporal contiguity cues, and reflects a type of object–location binding that is primarily tied to the original object location and that may only update to the object’s new location if there is time for the features to be re-encoded and rebound following the movement.  相似文献

This paper is an in-depth qualitative study based on interviews with 10 Finnish children who were evacuated to Sweden during Second World War and who did not return to Finland after the war. The interviewees were asked to tell about their lives. Nine of them were between 2 and 5 years and one was 7 years old at the time of evacuation. The aim was to study how their childhood experiences were reflected in adult memories, how they remembered or did not remember. This paper focuses on the consequences of not knowing about one’s early life and also on whether it is possible to observe signs of the Finnish mother. She did not appear explicitly but could be sensed in the tendency of the interviewees to express negations, displacement and active denial. The interviewers’ countertransference gave a sense of the unspoken but present, as feelings of shame and diffuse anger. The difficulty for the interviewees to think about or reflect over the loss of mother and the experience of evacuation led to a reduced ability to create meaning – in the sense of knowing oneself. We also looked for a comprehensive picture of the war children’s experience.  相似文献

Little is known about early life diet as a risk factor for early-onset persistent conduct problems (EOP CP). To investigate this, we used data from the Avon Longitudinal Study of Parents and Children, a UK-based prospective epidemiological birth cohort. 5727 mother-child pairs (49.9 % boys) monitored since pregnancy (delivery date between 1 April, 1991 and 31 December, 1992) reported intake of fish and processed foods at 32 weeks gestation and, for the child, at 3 years; EOP (n = 666) and Low conduct problem (Low CP, n = 5061) trajectories were measured from 4 to 13 years; hyperactivity and emotional difficulties were assessed in childhood (4–10 years) and early adolescence (12–13 years), in addition to potential confounding factors (family adversity, birth complications, income). Compared to Low CP, mothers of EOP children consumed less fish (p < 0.01) and more processed food (p < 0.05) prenatally, while EOP children consumed more processed food at 3 years (p < 0.05). For EOP, but not Low CP children, consuming less than two servings/week of fish (vs. two or more servings/week, p < 0.05), and one or more servings/day of processed food (vs. less than one serving/day, p < 0.01), was associated with higher emotional difficulties in early adolescence. Conclusions: Findings suggest that prenatal and postnatal diets high in processed food, and low in fish, associate with an EOP CP trajectory and co-occurring difficulties in early adolescence. As small effect size differences were found, further studies are needed to investigate the long-term impact of early unhealthy diet.  相似文献

Political psychologists have been quick to use prospect theory in their work, realizing its potential for explaining decisions under risk. Applying prospect theory to political decision‐making is not without problems, though, and here we address two of these: (1) Does prospect theory actually apply to political decision‐makers, or are politicians unlike the rest of us? (2) Which dimension do politicians use as their reference point when there are multiple dimensions (e.g., votes and policy)? We address both problems in an experiment with a unique sample of Dutch members of parliament as participants. We use well‐known (incentivized) decision situations and newly developed hypothetical political decision‐making scenarios. Our results indicate that politicians’ deviate from expected utility theory in the direction predicted by prospect theory but that these deviations are somewhat smaller than those of other people. Votes appear to be a more important determinant of politicians’ reference point than is policy.  相似文献

The purpose of the current study was to examine the factorial validity of existing grit measures and to examine differences in the grit level of athletes across performance tiers (i.e., collegiate, professional, Olympic). Female soccer players (N = 305) of varying competitive levels completed measures of grit. Results revealed preliminary support for the 8-item Grit Scale factorial validity, as well as a significant age-adjusted difference in grit level between Division I and Division II collegiate athletes. Taken together, study results prompt questions regarding the theoretical underpinnings, and consequent measurement, of the grit construct in sport psychology practice.  相似文献

Background and objectives: Recent research has shown day-level differences in an individual’s experience of uncivil behavior; however, it is unknown if that experience follows a consistent weekly change pattern. This study extends incivility theory and research by applying latent growth curve (LGC) modeling to diary study data to understand day-to-day changes in incivility.

Design: The authors took a theory-driven approach, reviewing both mood and recovery theory that would support a decrease in incivility over the working week.

Methods: Diary survey methodology was used, with a morning and evening survey completed on five consecutive workdays by 171 (73% of the 235 who initially volunteered, 95% of those who completed any surveys) employees in the legal industry. LGC analysis was used to identify patterns of experienced incivility, mood (both measured after work), and recovery (assessed the following morning).

Results: Regardless of job demands and gender, a weekly pattern was identified with the likelihood of experiencing incivility (coded as 0?=?none, 1?=?some) decreasing from Monday to Friday by .78 each day (p?<?.001) in a relatively linear fashion with a slope factor of .34 (SE?=?0.23; p?>?.05), indicating invariance between individuals. This weekly pattern was not explained by changes in mood or recovery.

Conclusions: Results emphasize the impact of contextual factors such as time on workplace incivility and the need to consider weekly rhythms of other behaviors that are likely to affect employee well-being and productivity. Although limited to one week of data per person, the findings are likely to be relevant to studies of other forms of interpersonal mistreatment, such as social undermining and interpersonal conflict.  相似文献

Public attitudes toward abortion have long been an issue in American political debates. Theoretical understanding of influences on abortion attitudes may assist researchers in determining contributors of the attribution. Accordingly, this study administered a 40-item abortion opinion survey to 396 college students at a Midwestern university to determine potential factors correlated with abortion attitudes. Several factors such as religious involvement, knowledge of someone who has an abortion, and one’s definition as to when life begins were correlated with abortion attitudes. Furthermore, Democrats reported stronger pro-choice views than Republicans did. Similarly, Liberals were more pro-choice oriented than Conservatives. Although causal relationships were not directly explored, theoretical explanations and support provide for a thorough understanding of potential factors of abortion attitude formation and a preliminary model. Future implications are also discussed.  相似文献
