Attitude theory has long proposed a mechanism through which antecedents of message elaboration produce attitude strength consequences. However, little direct evidence exists for the intervening process. The proposed thoughtfulness heuristic holds that perceiving that more thought has taken place leads to greater attitude certainty. Two roles were established for this heuristic: first as a mediator of the impact of antecedents of elaboration on attitude certainty and second as a way to influence attitude certainty independent of actual elaboration. In Studies 1 and 2, antecedents of elaboration (need for cognition, distraction) impacted attitude certainty because they impacted the actual amount of processing, which in turn affected perceptions of the amount of processing. In Studies 3 and 4, a manipulation of perceived thought impacted certainty independent of actual thought (i.e., after thinking had already occurred). Furthermore, the thoughtfulness heuristic was shown to influence behavioral intentions, establishing perceived amount of processing as both a mediator and an independent cause of attitude strength consequences. 相似文献

The current study examined social support and stress as mediators of the hostility—coronary heart disease (CHD) relationship
as suggested by the psychosocial vulnerability model in a sample of low-income African Americans. Among 95 CHD patients and
30 healthy controls, hostility was negatively correlated with social support, but was not related to minor stress. CHD patients
endorsed higher levels of hostility; however, the relationship between hostility and CHD status was diminished once stress
and social support were included in the model. This study lends partial support for the psychosocial vulnerability model of
hostility in African Americans, but suggests that the relationship between hostility and stress may be impacted by socioeconomic
status. 相似文献

The present study investigated the effects of anticipation on skin conductance while participants were answering a set of questions which included one of concealed knowledge. Two experiments were conducted. In Exp. 1, 26 participants completed one experimental session. Each participant was asked to choose one two-digit number from 10 to 99 and was presented 19 other randomly generated two-digit numbers. The list of numbers was then presented to the participant on a computer screen, with a 60-sec. interval occurring every two questions. The participant-selected number was defined as the target question which was randomly placed within the 4th to 17th item of 20 questions stated as follows: "Is your selected number?" The participant was asked to answer "No" to all questions. The skin-conductance response to each question was measured. In Exp. 2, the experimental procedure was the same as that in Exp. 1 except each participant first answered 10 nontarget questions, then answered a target question with the participant's selected number, and then answered another 10 nontarget questions. There were a total of 21 questions. Analysis indicated participants in both experiments generated the highest mean skin conductance while answering the target questions, followed by lower amplitudes to questions prior to and after the target question. The skin-conductance response pattern can be used to identify the psychological process of anticipation of concealed information. 相似文献

Environmental familiarization is a learning phenomenon embedded within most tasks used to study learning and motivation. Given its prevalence there is surprisingly little systematic behavioral research on factors affecting familiarization. The six experiments reported in the present report used rats’ tendency to interact more with a novel object in a familiar than in a novel environment as a measure of environmental familiarization. We found that 3 min of exposure to the environment was sufficient to increase object interaction above unfamiliar controls even when testing occurred up to 48 h after initial exposure to the environment; 1 or 1.5 min of exposure was not sufficient. Also, in the brief 2 min test, 10 min of environment exposure did not appear to increase object interaction above the 3-min condition. The 3-min of environment exposure was sufficient for familiarization whether environment exposure occurred in one 3 min placement or two 1.5 min placements. Environmental familiarization as measured by object interaction was also sensitive to ‘interference’ manipulations. That is, a distinct object present during initial exposure to the environment produced a level of object interaction in testing comparable to an unfamiliar control. Similarly, exposure to a second distinct alternate environment immediately after, but not before, initial exposure to the test environment partially disrupted environmental familiarization. In sum, object interaction might serve as a useful measure for studying processes mediating environmental familiarity. 相似文献

Organizational socialization tactics and newcomer proactive behaviors: An integrative study 总被引:1,自引:0,他引:1
The purpose of this study was to examine the relationship between organizational socialization tactics, newcomers’ self-efficacy, proactive behaviors, and socialization outcomes. Based on a sample of 140 co-op university students who completed surveys at the end of their work term, the results indicated that newcomers’ self-efficacy and institutionalized socialization tactics were positively related to newcomer proactive behaviors. The results also indicated that newcomer proactive behaviors partially mediated the relationship between their self-efficacy and organizational socialization tactics with a number of proximal and distal socialization outcomes. Furthermore, feedback-seeking and information-seeking moderated the relationship between socialization tactics and several socialization outcomes. Institutionalized socialization tactics were more strongly related to socialization outcomes for newcomers who engaged in less feedback-seeking and information-seeking behavior. These results support an interactionist approach to organizational socialization in which newcomers’ self-efficacy, proactive behavior, and organizational socialization tactics all contribute to newcomers’ adjustment and socialization. 相似文献

Many researchers have tackled the question of how behavior is influenced by its outcomes. Some have adopted a nonmechanistic (functional) perspective that attempts to describe the influence of outcomes on behavior. Others have adopted a mechanistic (cognitive) perspective that attempts to explain the influence of outcomes on behavior. Orthogonal to this distinction, some have focused on the influence of outcomes that a behavior had in the past, whereas others also consider the influence of outcomes that a behavior might have in the future. In this article, we relate these different perspectives with the goal of reducing misunderstandings and fostering collaborations between researchers who adopt different perspectives on the common question of how behavior is influenced by its outcomes. 相似文献

This study aimed to describe the distribution of positive psychosis symptoms in a large scale, population-based sample. Data from the British Psychiatric Morbidity Survey was used to examine homogeneous sub-types of participants based on their responses to the five probe items of the Psychosis Screening Questionnaire. Latent class analysis was used to identify the underlying class structure of psychosis. Four classes of psychosis were identified. Associations between the latent classes and the demographic risk factors, clinical variables and reports of traumatic experiences showed significantly higher risks for the psychosis class, the paranoid class, and the intermediate class compared to the normative class. Four classes that appeared to represent an underlying continuum could best explain psychosis symptom expression at the population level. 相似文献

Words associated with perceptually salient, highly imageable concepts are learned earlier in life, more accurately recalled, and more rapidly named than abstract words (R. W. Brown, 1976; Walker & Hulme, 1999). Theories accounting for this concreteness effect have focused exclusively on semantic properties of word referents. A novel possibility is that word structure may also contribute to the effect. We report a corpus-based analysis of the phonological and morphological structures of a large set of nouns with imageability ratings (N = 2,023). High- and low-imageability nouns differed by length, etymology, prosody, affixation, phonological neighborhood density, and rates of consonant clustering. On average, nouns denoting abstract concepts were longer, more derivationally complex, and emerged in English from a different distribution of languages than did concrete nouns. We address implications for interactivity of word form and meaning as pertain to theories of word concreteness, lexical acquisition, and word processing. 相似文献

It has been hypothesized that cognitive mechanisms underlying lateralized complex motor actions associated with tool use in chimpanzees may have set the stage for the evolution of left-hemisphere specialization for language and speech in humans. Here we report evidence that asymmetries in the homologues to Broca's and Wernicke's areas are associated with handedness for tool use in chimpanzees. These results suggest that the neural substrates of tool use may have served as a preadaptation for the evolution of language and speech in modern humans. 相似文献

As some states allow motorists to use hands-free cell phones only while driving, this study was done to examine some braking responses to see if conversing on these two types of cell phones affects quick responding. College-age drivers (n=25) completed reaction time trials in go/no-go situations under three conditions: control (no cell phone or conversation), and conversing on hands-free and hand-held cell phones. Their task involved moving the right foot from one pedal to another as quickly as possible in response to a visual signal in a lab setting. Significantly slower reaction times, movement times, and total response times were found for both cell phone conditions than for the control but no differences between hands-free and hand-held phone conditions. These findings provide additional support that talking on cell phones, regardless if it is hands-free or hand-held, reduces speed of information processing. 相似文献
