Previous research demonstrates that implicitly learned probability information can guide visual attention. We examined whether the probability of an object changing can be implicitly learned and then used to improve change detection performance. In a series of six experiments, participants completed 120–130 training change detection trials. In four of the experiments the object that changed color was the same shape (trained shape) on every trial. Participants were not explicitly aware of this change probability manipulation and change detection performance was not improved for the trained shape versus untrained shapes. In two of the experiments, the object that changed color was always in the same general location (trained location). Although participants were not explicitly aware of the change probability, implicit knowledge of it did improve change detection performance in the trained location. These results indicate that improved change detection performance through implicitly learned change probability occurs for location but not shape. 相似文献

Laboratory studies have shown considerable differences between the eating behavior, particularly binge eating behavior, of participants with and without binge eating disorder (BED). However, these findings were not replicated in two field experiments employing ecological momentary assessment (EMA) in which obese BED and obese non-BED participants reported comparable binge eating behavior. In the current study, we examined differences in binge eating with an innovative assessment scheme employing both EMA and a standardized computer-based dietary recall program to avoid some of the limitations of past laboratory and field research. Obese BED, obese non-BED, and non-obese control participants reported significant differences in eating patterns, loss of control, overeating, and binge eating behavior. Of particular importance was the finding that BED participants engaged in more overeating and more binge eating episodes than non-BED participants. These findings suggest that the use of EMA in combination with dietary recall may be a relatively objective and useful approach to assessing binge eating behavior. The findings further suggest that individuals with BED are observably different from those without the disorder, which may have implications for eating disorder diagnoses in DSM-V. 相似文献

ABSTRACT— Psychology would be improved if researchers stopped using complicated designs, procedures, and statistical analyses for the sole reason that they are able to do so. The present article reviews some of the classic studies in psychology, all of which are breathtakingly simple. The notion of minimally sufficient research is suggested as an ideal worth following. More generally, questions should dictate research methods and statistical analyses, not vice versa. 相似文献

Complex social stimuli (like faces) can be studied using a methodology typically reserved for studying lights, tones, and
colors: psychophysics. Given that psychophysics examines how humans detect and respond to stimuli in their environment, we
can extend that to the study of how humans detect social stimuli in the environment. Using psychophysical methodology to answer
“social” questions provides another dimension of experimental manipulation and control to the diverse array of methodologies
already used by social psychologists. In this article, we review psychophysical methodology, provide a rationale for social
psychophysics, describe an easy-touse software program called PsychoPro, for collecting psychophysical data, and present data
collected using this program to examine racial thresholds that provide evidence for a cognitive gating mechanism for racial
information that impacts face processing (MacLin & MacLin, 2007, in press; MacLin, MacLin, & Peterson, 2008). 相似文献

This study examined the relations of adolescents’ perceptions of pressures from the media, their mothers, and their peers with the development of eating disorder symptomology. Participants were 333 male and female adolescents in high school grades 10–12 from a suburban area of the Midwestern US. During the school day, students completed Likert-type scales of perceived pressures and eating disorder symptomology. Canonical correlations showed that students who perceived greater pressures across all three environmental contexts also reported more eating disorder symptomology. However, the patterns of relations between the perceived pressures and specific eating disorder symptoms differed by gender. Implications for future research and prevention programs are discussed. 相似文献

Generativity and authoritarianism assessed at age 52 were correlated with criterion variables assessed at age 62 in a sample of well-educated women (N = 81). Results indicated that generativity predicted positive personality characteristics, satisfaction with marriage and motherhood, and successful aging. By contrast, although authoritarianism is linked in the literature to endorsing traditional gender roles, authoritarianism was uncorrelated in the current study with happiness about marriage and was negatively related to perceptions of motherhood. Furthermore, authoritarianism was correlated with neuroticism later in life. These data suggest that midlife authoritarianism may be problematic as women transition from their 50s to their 60s. Midlife generativity, in contrast, seems to offer one path to life satisfaction. 相似文献

This paper is a reply to Redmond and colleagues’ brief report that argues we (Peterson et al., 2003a) were not the first to establish the unreliability of the computerised cognitive styles analysis (CSA) test because we used a copy of the test rather than the original. We refute this suggestion and argue that we have already defended our approach to testing the CSA’s reliability (Peterson et al., 2003b) and that our method is entirely appropriate and transparent. Rather than argue over who was the first to test the CSA’s reliability, we believe we should celebrate the fact that we both found the same result, regardless of the method used. 相似文献

In 3 studies, the authors developed and began to validate a measure of the propensity to act rashly in response to positive affective states (positive urgency). In Study 1, they developed a content-valid 14-item scale, showed that the measure was unidimensional, and showed that positive urgency was distinct from impulsivity-like constructs identified in 2 models of impulsive behavior. In Study 2, they showed that positive urgency explained variance in risky behavior not explained by measures of other impulsivity-like constructs, differentially explained positive mood-based risky behavior, differentiated individuals at risk for problem gambling from those not at risk, and interacted with drinking motives and expectancies as predicted to explain problem drinking behavior. In Study 3, they confirmed the hypothesis that positive urgency differentiated alcoholics from both eating-disordered and control individuals. 相似文献

Issues of the nature and task of theology remain important to the science-theology dialogue. This paper lays out a framework for understanding the nature of theology in relation to the other sciences. In particular, I argue that the primary question remains one of autonomy and reduction. If theology is a genuine academic discipline, then it should be an autonomous field with its own subject matter and norms. Wolfhart Pannenberg argues that theology is the science of God, but I suggest that theology be more broadly understood as the science of meaning. If we recognize this, the modes of interaction between theology and the other sciences becomes clearer. 相似文献

Data suggests that individuals who binge eat are more responsive to food cues in the environment and less sensitive to satiety cues. The aim of this open trial was to evaluate the feasibility, acceptability, and initial effectiveness of a novel treatment grounded in Schachter’s externality theory targeting food cue reactivity and satiety responsiveness with obese adults who binge eat. Treatment was provided in groups, and utilized appetite monitoring, cue-exposure treatment, in vivo exercises, self-monitoring, and coping skills. Twenty-eight overweight and obese adults who binge eat (82% female; mean age = 47.5 years [SD = 12.8]; BMI = 38.9 [SD = 10.3]; 79% White non-Hispanic) participated in a 4-month group-based treatment program. Assessments were conducted at baseline, posttreatment, and 3-month follow-up time points. Results indicated that this treatment was well accepted and had high retention at posttreatment. Initial effectiveness showed significant decreases in BMI, and improvements in loss of control and overeating episodes, food responsiveness, and power of food. The majority of results were maintained at the 3-month follow-up time point. This open trial provides preliminary evidence for the feasibility, acceptability, and initial effectiveness of this treatment on both eating disorder symptoms and weight in obese adults who binge eat. Because these data are preliminary, further treatment development and randomized controlled studies are needed. 相似文献
