The Effects of Mandatory Time Limits in the Voting Booth on Liberal-conservative Voting Patterns 总被引:1,自引:0,他引:1
Robert O. Hansson John P. Keating Carmen Terry 《Journal of applied social psychology》1974,4(4):336-342
One hundred and forty college students, in either (a) 2-minute time-limit or (b) a no-time-limit condition, voted their conscience on actual pending legislation in their state in a test of hypothesis that such time limits in the voting booth created a stimulus overload situation. Such a situation was expected to result in dysfunctional adaptation responses, with unintended effects on voting patterns. Results indicated that subjects in the time stress condition voted significantly more conservatively on these issues. This conservative shift is interpreted as a function of overload, with serious political implications for urban planners, whose response to increasing population density often has been to increase the tempo by which citizens are processed through the cities'institutional and social services. 相似文献

Two explanations for the Yerkes-Dodson Effect (1908) were tested. Easterbrook (1959) proposed that arousal reduces the range of cue utilization. Thus, arousal should interfere with the capacity for simultaneous (dual) memory scans. In contrast, Humphreys and Revelle (1984) proposed that arousal facilitates sustained information transfer but interferes with short-term memory. Arousal should thus reduce the time needed to prepare to respond but increase the time needed to scan memory. Either caffeine or placebo was given to 78 subjects who differed in impulsivity. They completed three versions of a memory-scanning task: two single-task versions (physical and category matches) and one dual-task version (either type of match). As predicted by Humphreys and Revelle, relative to placebo, caffeine lowered the intercept (p<.01), suggesting facilitation of sustained information transfer, but increased the slope (p<.05), suggesting impairment of access to short-term memory, of the regression of reaction time on log-transformed memory-set size. That caffeine had a main effect on slopes and on intercepts but did not interact with type of task suggests that arousal does not necessarily disrupt dual-task performance. 相似文献

Recently psychologists have formulated a comprehensive view of attention involving allocation of processing capacity. Although developmental changes in processing capacity have been proposed as one source of age differences in certain cognitive skills, there has been little systematic investigation of this hypothesis. In the present study, second and sixth graders and adults (8, 12, and 20 years of age, respectively) performed a letter-matching task (primary task) concurrently with an auditory detection task (secondary task). Changes in reaction time in the secondary task as a function of manipulations of the primary task were used to estimate capacity allocation to the primary task. Primary task variables included stage of processing (alerting, encoding, rehearsing, responding) and matching condition (physical-identity vs name-identity matching). Age differences in secondary task performance were found to be related to stage of processing but not to matching condition. Earlier stages of the letter match task (alerting, encoding) required somewhat more capacity allocation in younger subjects. Later stages (rehearsing, responding) made substantially higher demands on capacity in children. Capacity allocation may be an important cognitive variable mediating developmental differences in basic information processing skills, and may underlie age trends found in performance of certain complex cognitive tasks. 相似文献

Under concurrent‐chains schedules of reinforcement, participants often prefer situations that allow selection among alternatives (free choice) to situations that do not (forced choice). The present experiment examined the effects of reinforcement probability on choice preferences. Preferences for free versus forced choice were measured under a condition in which participants' choices were always reinforced (reinforcement probability of 1.0) and a condition in which outcomes were uncertain (reinforcement probability of 0.5). Forty‐four college students participated and preferences were examined under a concurrent‐chains schedule of reinforcement. Participants preferred free choice under uncertain reinforcement, but a bias toward free choice was not observed when reinforcement was certain. These results align with previous findings of preference for free choice under conditions of uncertainty, but suggest that preference may be dependent upon probabilistic reinforcement contingencies in the terminal links of the concurrent‐chains arrangement. Thus, reinforcement probability is an important variable to consider when conducting similar studies on the value of choice. 相似文献

Child maltreatment can lead to a unique set of trauma stress among young children that can be challenging to measure. The purpose of this review was to review measures of maltreatment-related trauma outcomes (trauma-related symptoms and post-traumatic stress disorders) in very young children (ages 0–6) and to examine research trends in how and if child development is accounted for in this area of measurement. A systematic search strategy was used to identify articles in two databases, CINAHL and PsychInfo. Articles were eligible for inclusion in the review if they measured trauma symptoms in children ages 0–6, were quantitative research reports of studies conducted in North America, and were published in English. The search resulted in 74 articles meeting prespecified inclusion criteria. Results suggested that recognition of the ways maltreatment trauma affects child development and the importance of developmental sensitivity in assessing trauma symptoms has grown in recent years. However, many research studies did not use developmental frameworks and applied adult-oriented trauma symptom frameworks in measurement and treatment. Behavioral symptoms were the primary outcome of interest for this age group. There was also incongruity and lack of consensus about diagnostic tools for post-traumatic stress disorders in young children. Further research is needed to resolve theoretical and empirical controversies related to measurement and diagnosis of trauma symptomatology in young children. 相似文献

Women’s sexual desire is a complex, multifaceted phenomenon. According to the biopsychosocial model of female sexual function, a comprehensive understanding of women’s sexuality requires awareness of the presence of and interaction between biological, psychological, interpersonal, and sociocultural factors. Other sexuality scholars in the field have similarly stressed this perspective, emphasizing that sexual desire in particular is impacted by medical, relational, psychological, and sociocultural influences. Given the influence of sociocultural variables like sexism and heterosexism on women’s lives, we sought to understand the impact of the sociocultural context on sexual desire in 31 bisexual, lesbian, and heterosexual women. Women ranged in age from 20 to 69 and answered a number of questions related to their experience of sexual desire and the ways in which desire related to their sexual identity. The semi-structured interviews focused on women’s retrospective, subjective accounts of their experiences. Using a consensual qualitative research approach and thematic analysis, the interviews revealed four themes and seven subthemes: (1) minority stress (heterosexist discrimination, stigmatized identities, coming out, impact of visible/safe spaces); (2) gender expectations (gendered relationship expectations, gender binary impacts, body image); (3) religion; and (4) taboo and changing cultural times. Participant responses suggest that the sociocultural context can influence the sexual desire of diverse women, supporting both sexual desire exploration and suppression of desire expression by context. Practice and advocacy considerations include understanding of the impact of systems of privilege and oppression (e.g., sexism, heterosexism, racism) on women’s sexual desire experiences and opportunities for supporting diverse women’s sexual empowerment. 相似文献

The investigation of the relation of positive personality characteristics to mental and physical health among Stroke survivors has been a neglected area of research. The purpose of this study was to examine the relationship between optimism, well-being, depressive symptoms, and perceived physical health among Stroke survivors. It was hypothesized that Stroke survivors’ optimism would explain variance in their physical health above and beyond the variance explained by demographic variables, diagnostic variables, and mental health. One hundred seventy-six Stroke survivors (97 females, 79 males) completed the Revised Life Orientation Test, the Center for Epidemiological Studies Depression Scale, two items on perceived physical health from the 36-item Short Form of the Medical Outcomes study, and the Identity scale of the Illness Perception Questionnaire. Pearson correlations, hierarchical regression analyses, and the PROCESS approach to determining mediators were used to assess hypothesized relations between variables. Stroke survivors’ level of optimism explained additional variance in overall health in regression models controlling for demographic and diagnostic variables, and mental health. Analyses revealed that optimism played a partial mediator role between mental health (well-being, depressive symptoms and total score on CES-D) variables and overall health. 相似文献

There is growing interest among organizational researchers in tapping into alternative sources of data beyond self-reports to provide a new avenue for measuring behavioral constructs. Use of alternative data sources such as wearable sensors is necessary for developing theory and enhancing organizational practice. Although wearable sensors are now commercially available, the veracity of the data they capture is largely unknown and mostly based on manufacturers’ claims. The goal of this research is to test the validity and reliability of data captured by one such wearable badge (by Humanyze) in the context of structured meetings where all individuals wear a badge for the duration of the encounter. We developed a series of studies, each targeting a specific sensor of this badge that is relevant for structured meetings, and we make specific recommendations for badge data usage based on our validation results. We have incorporated the insights from our studies on a website that researchers can use to conduct validation tests for their badges, upload their data, and assess the validity of the data. We discuss this website in the corresponding studies. 相似文献

The authors examined the degree to which callous-unemotional traits and narcissism predict relational aggression, social aggression, and prosocial skills in a sample of 79 adolescent offenders (13–18 years old; 26% girls; 74% boys) attending a school for youth with behavior disorders in the Mid-Atlantic United States. Narcissism made a significant contribution to the prediction of both relational aggression and social aggression, accounting for most of the unique variance in the prediction of these indirect forms of aggression. Conversely, callous-unemotional traits—but not narcissism—made a significant contribution to the prediction of lower prosocial skills. Furthermore, in contrast to the large number of studies indicating gender differences in the expression of aggression, no significant gender differences in the present study were found. 相似文献
