Reducing concussion risks in athletes depends on self‐reporting. Often, athletes decide whether to report concussions or continue playing and risk serious health consequences. Fuzzy‐trace theory (FTT) predicts that reliance on gisty, categorical representations of risky decisions, not amounts of risk/reward, encourages risk avoidance and application of bottom‐line values, or gist principles, thus promoting healthy decisions. Applying FTT, we test whether intentions to report are predicted by gist‐based thinking about risks and values. High school and college students (N = 1,366) were assessed for concussion knowledge, social pressures to not report (by coaches/parents/teammates), categorical gist‐based thinking, endorsement of gist principles expressing values, and intentions to report. As expected, the older group scored higher on gist measures. For young adults, categorical thinking, and gist principles predicted intentions, controlling for sex, knowledge, and social pressures. For adolescents, categorical thinking again predicted intentions. For both age groups, adding FTT's predictors accounted for significantly more variance than baseline models. 相似文献

Although precision is often important in quantitative judgment, sometimes, it is valuable to recognize that two quantities are roughly the same. Fuzzy‐trace theory suggests that approximately equal judgments rely on gist representations (i.e., meaningful fuzzy categories of quantity). We conducted three experiments to investigate approximately equal judgments with number pairs presented in different formats, both with and without semantic content (breast cancer statistics). In each study, the ratio of the smaller divided by larger number predicted approximately equal judgments. Experiment 1 also examined how knowledge of breast cancer, presentation format (frequencies vs. percentages), and differences in gist comprehension of breast cancer information influence fuzzy equality judgments. As predicted by the fuzzy‐trace theory concept of denominator neglect, approximately equal judgments were more sensitive, as measured by signal detection theory (SDT) analyses, when presented as percentages. In both experiments with breast cancer statistics, people were more likely to judge number pairs approximately equal when they were embedded in sentences about breast cancer, and breast cancer knowledge predicted increased perception of equality, when appropriately consistent with reliable sources, and increased judgment sensitivity. In Experiment 2, a simple intervention focusing on gist meaning increased source‐consistent approximately equal judgments, increased SDT judgment sensitivity, and decreased SDT response bias. In Experiment 3, using number pairs devoid of semantic context spanning four orders of magnitude, we further examined ratio similarity. Overall, more knowledgeable judges and those who better understood the gist of meaningful numbers were more likely to judge literally different numbers as “approximately equal” rather than make precise discriminations that were meaningless.

Children with pediatric feeding disorder may refuse to consume an adequate variety and/or volume of food to maintain expected growth. They can consume food but may actively or passively refuse, resulting in escape or avoidance of eating. Behavioral interventions like positive reinforcement with escape extinction can increase consumption. However, sometimes these interventions are insufficient, especially in treating passive refusal. In these cases, physical guidance may be used to prompt an open mouth to deposit food. Research indicates open-mouth prompts are effective and rated as acceptable. This study replicated an existing physical guidance procedure, the finger prompt, and compared its efficacy and acceptability with that of a spoon prompt. This study extended research by defining and measuring passive refusal as a dependent variable and assessing social validity among different stakeholders and times. Both prompts were effective in treating food refusal, and caregivers rated the finger prompt as more preferred. 相似文献

The hippocampal formation is known for its importance in conscious, declarative memory. Here, we report neuroimaging evidence in humans for an additional role of the hippocampal formation in nonconscious memory. We maskedly presented combinations of faces and written professions such that subjects were not aware of them. Nevertheless, the masked presentations activated many of the brain regions that unmasked presentations of these stimuli did. To induce a nonconscious retrieval of the faces and face-associated occupational information, subjects were instructed to view the previously masked faces and to guess the professional category of each person--academic, artist, and workman. Guessing the professional category of previously masked versus new faces activated the left and right hippocampal formation and right perirhinal cortex as well as bilateral fusiform areas and fronto-temporal areas known to mediate the retrieval of semantic information. These activations within the semantic processing system suggest that conceptual knowledge acquired during masking was nonconsciously retrieved. Our data provide clues to an analogous role of the hippocampus in conscious and nonconscious memory. 相似文献

Packing is a problematic mealtime behavior that is characterized by pocketing or holding solids or liquids in the mouth without swallowing. In the current study, we examined the effects of a chaser, a liquid or solid consistently accepted and swallowed by the child, to decrease packing of solid foods in 3 children with feeding disorders. During the chaser procedure, the therapist presented the chaser immediately for 2 children or 15 s after each bite presentation for 1 child. The chaser was effective in decreasing packing for all 3 children. The results are discussed in terms of the clinical importance of the findings and directions for future research. 相似文献

The effect of exposure to the contextual features of the /pt/ cluster was investigated in native-English and native-Polish listeners using behavioral and event-related potential (ERP) methodology. Both groups experience the /pt/ cluster in their languages, but only the Polish group experiences the cluster in the context of word onset examined in the current experiment. The /st/ cluster was used as an experimental control. ERPs were recorded while participants identified the number of syllables in the second word of nonsense word pairs. The results found that only Polish listeners accurately perceived the /pt/ cluster and perception was reflected within a late positive component of the ERP waveform. Furthermore, evidence of discrimination of /pt/ and /p?t/ onsets in the neural signal was found even for non-native listeners who could not perceive the difference. These findings suggest that exposure to phoneme sequences in highly specific contexts may be necessary for accurate perception. 相似文献

A large proportion of emerging adults treated for substance use disorder (SUD) present with symptoms of negative affect and major depressive disorder (MDD). However, little is known regarding how these comorbidities influence important mechanisms of treatment response, such as increases in abstinence self-efficacy (ASE). This study tested the degree to which MDD and/or depressive symptoms interacted with during-treatment changes in ASE and examined these variables' relation to outcome at 3 months' posttreatment. Participants (N = 302; 74% male) completed measures at intake, midtreatment, end-of-treatment, and at 3-month follow-up. ASE was measured with the Alcohol and Drug Use Self-Efficacy (ADUSE) scale; depressive symptoms were assessed with the Brief Symptom Inventory 18 (BSI 18) Depression scale; and current MDD diagnoses were deduced from the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Random coefficient regression analyses focused on during-treatment changes in ASE, with BSI 18 scores and MDD diagnosis included as moderators. At intake, individuals with MDD or high levels of depressive symptoms had significantly lower ASE, particularly in negative affect situations. No evidence for moderation was found: ASE significantly increased during treatment regardless of MDD status. There was a main effect of BSI 18 Depression scores: those with lower BSI 18 scores had lower ASE scores at each time point. MDD and BSI 18 Depression did not predict 3-month outcome, but similar to previous findings ASE did predict abstinence status at 3 months. Treatment-seeking emerging adults with MDD merit particular clinical attention because of their lower reported self-efficacy throughout treatment. 相似文献

Previewing scenes briefly makes finding target objects more efficient when viewing is through a gaze-contingent window (windowed
viewing). In contrast, showing a preview of a randomly arranged search display does not benefit search efficiency when viewing
during search is of the full display. Here, we tested whether a scene preview is beneficial when the scene is fully visible
during search. Scene previews, when presented, were 250 ms in duration. During search, the scene was either fully visible
or windowed. A preview always provided an advantage, in terms of decreasing the time to initially fixate and respond to targets
and in terms of the total number of fixations. In windowed visibility, a preview reduced the distance of fixations from the
target position until at least the fourth fixation. In full visibility, previewing reduced the distance of the second fixation
but not of later fixations. The gist information derived from the initial glimpse of a scene allowed for placement of the
first one or two fixations at information-rich locations, but when nonfoveal information was available, subsequent eye movements
were only guided by online information. 相似文献

This study explored individual and military risk factors for intimate partner aggression (IPA) perpetration among Navy personnel in their second year of service. We found some evidence that job stress was related to higher perpetration among men. Contrary to expectations, ship duty was related to lower perpetration rates, even though it involves more military operational stress and more frequent deployments than does shore duty. Premilitary alcohol problems were a stronger risk factor for men than for women, whereas premilitary patterns of aggressive behavior were a stronger risk factor for women. Recommendations for future research and public health interventions are discussed. 相似文献
