Involvement has long been theoretically specified as a crucial factor determining the persuasive impact of messages. In social judgment theory, ego‐involvement makes people more resistant to persuasion, whereas in dual‐process models, high‐involvement people are susceptible to persuasion when argument quality is high. It is argued that these disparate predictions might be reconciled by either different involvement types (i.e., value relevant vs. outcome relevant) or different attitude modification processes (i.e., attitude change vs. attitude formation). An experiment (N = 684) varying topic, position advocated, outcome relevance, and argument quality tested these moderators. The data were consistent with existence of two different types of involvement, but none of the theoretical predictions were consistent with the data. Instead, a main effect for argument quality had the largest impact on attitude change. Regardless of value‐relevant involvement, outcome‐relevant involvement, and attitude modification process, participants were more persuaded by high‐ rather than low‐quality arguments, with boomerang effects observed for low‐quality arguments. These findings highlight the importance of sound message design in persuasion. 相似文献

A fundamental concern when using visual presentations to study cerebral asymmetry is to ensure that stimuli are presented with the same degree of retinal eccentricity from a central fixation point in either visual field. However, a widely used procedure intended to control fixation location merely instructs participants to fixate appropriately without any other means of ensuring that central fixations actually occur. We assessed the validity of assuming that instructions alone ensure central fixation by using the traditional R VF advantage for words and either (a) only instructions to fixate centrally, or (b) an eye-tracking device that ensured central fixation on every trial. Experiments 1 and 2 found that when only instructions were given, the vast majority of fixations were not central, and more occurred to the right of centre than to the left. Moreover, the prevalence of non-central fixations was otherwise disguised by the finding that both fixation procedures produced similar R VF advantages in overt performance. The impact of typical non-central fixations on performance was revealed by systematically manipulating fixation location in Experiment 3, where deviations in fixation of only 0.25 from centre had a reliable impact on visual field effects. Implications of these findings for studies of cerebral asymmetry are discussed. 相似文献

Anger can be defined as an emotion consisting of feelings of variable intensity, from mild irritation or annoyance to intense fury and rage. Borderline personality disorder (BPD) is characterized by impulsivity and instability of interpersonal relationships, of self-image, and of negative affects. Borderline personality and trait anger are often observed together. The present study examined the extent to which a genetic association explains the covariation between a trait measure of borderline personality and trait anger. To this end, self-report data of 5,457 twins and 1,487 of their siblings registered with the Netherlands Twin Register and the East Flanders Prospective Twin Survey were analyzed using genetic structural equation modeling. A significant phenotypic correlation was observed between the two traits (rP = .52). This correlation was explained by genetic (54%) and by environmental influences (46%). A shared genetic risk factor is thus one of the explanations for the covariation of borderline personality and trait anger. 相似文献

This study examined the effects of a mass-media video intervention on expectations, attitudes, and intentions to seek help from professional mental health care services. A public service announcement-style, mass-media video intervention was developed, with prior empirical research on help-seeking behaviors organized according to the theory of reasoned action/planned behavior. In total, 228 participants were randomly assigned to 1 of 2 conditions: (a) the media-exposed intervention group, who watched programming in which the media intervention was inserted, and (b) the control group, who watched the same programming without the media intervention. The media intervention was not influential on expectation and belief-based barrier variables. However, the media intervention was effective at increasing positive attitudes toward help seeking. Findings regarding the intervention's ability to increase help-seeking intentions for interpersonal problems were complex. Implications of these findings for future research are discussed. 相似文献

Four experiments examined relapse of extinguished observing behavior of pigeons using a two-component multiple schedule of observing-response procedures. In both components, unsignaled periods of variable-interval (VI) food reinforcement alternated with extinction and observing responses produced stimuli associated with the availability of the VI schedule (i.e., S+). The components differed in the rate of food arranged (Rich = VI 30 s; Lean = VI 120 s). In Experiment 1, following baseline training, extinction of observing involved removal of both food and S+ deliveries, and reinstatement was examined by presenting either response-independent food or S+ deliveries. In Experiment 2, extinction involved removal of only food deliveries while observing responses continued to produce S+. Reinstatement was examined by delivering food contingent upon the first two food-key responses occurring in the presence of the S+. Experiment 3 assessed ABA renewal of observing by extinguishing food-key and observing responses in the presence of one contextual stimulus (i.e., B) and then returning to the original training context (i.e., A) during continued extinction. Experiment 4 examined resurgence by introducing food reinforcement for an alternative response during extinction, and subsequently removing that alternative source of food. Across experiments, relative resistance to extinction and relapse of observing tended to be greater in the component previously associated with the higher rate of primary reinforcement. Relapse of observing or attending to stimuli associated with primary reinforcement appears to be impacted by frequency of primary reinforcement in a manner similar to responding maintained directly by primary reinforcement. 相似文献
