Determinants of brand switching: the role of consumer inferences,brand commitment,and perceived risk
Previous research in the area of price discounts has generated a rich, but diverse and mixed body of literature. This research examines the role of consumer's brand commitment and product category risk in influencing the nature as well as valence of the inferences generated by consumers in response to price discounts. Our results provide insights regarding how consumers' responses to competitor inducements vary depending upon their brand commitment for the incumbent brand and perceived risk. Furthermore, we show that higher commitment consumers could resist an inducement from a competitor when they are able to generate negative, marketer‐related inferences. Our research suggests that consumers' inferences are critical than pure economic benefits in determining the effectiveness of discounts. 相似文献

Adult male Wistar rats were bilaterally implanted with indwelling cannulae in the caudal region of the posterior cingulate cortex. After recovery, animals were trained in a step-down inhibitory avoidance task (3.0-s, 0.4-mA foot shock) and received, right after training, a 0.5-microl infusion of vehicle (phosphate-buffered saline, pH 7.4), of the GABA(A) receptor agonist muscimol (0.1 or 0.5 microg), of the cAMP-dependent protein kinase (PKA) stimulant Sp-cAMPS (0.1 or 0.5 microg), or of the PKA inhibitor Rp-cAMPS (0.1 or 0.5 microg). Animals were tested twice, 1.5 h and, again, 24 h after training, in order to examine the effects of these agents on short- and long-term memory, respectively. Muscimol (0.5 but not 0.1 microg) hindered retention for both short- and long-term memory (p <.05). Rp-cAMPS (0.1 or 0.5 microg) hindered retention for short-term memory (p <.05). In addition, these animals showed lower, but not significantly lower, latencies than controls in the test session for long-term memory (p >.10). A trend toward an amnesic effect on long-term memory was also observed after Sp-cAMPS infusion at 0.1 microg (p <.10). These results show that strong stimulation of GABAergic synapses in the caudal region of the rat posterior cingulate cortex right after training impairs short- and long-term memory (the latter less dramatically). The same occurs by inhibiting PKA activity with regard to STM and possibly to LTM. 相似文献

The ability to understand and generate hierarchical structures is a crucial component of human cognition, available in language, music, mathematics and problem solving. Recursion is a particularly useful mechanism for generating complex hierarchies by means of self-embedding rules. In the visual domain, fractals are recursive structures in which simple transformation rules generate hierarchies of infinite depth. Research on how children acquire these rules can provide valuable insight into the cognitive requirements and learning constraints of recursion. 相似文献

Young children at sociodemographic risk generally demonstrate lower executive control (EC), although with substantial heterogeneity across children. Given this marked variability, there may be some at-risk children who display higher EC and may be buffered from or resilient to the effects of sociodemographic risk who can be studied to identify the contributory factors. In this study, factor mixture modelling was used to determine whether subgroups of 3-year-old children existed based on their observed performance on a battery of EC tasks. Results indicated 2 latent groups: One characterized by lower EC and the other by higher EC. Both sociodemographically at-risk and low-risk children were represented in each group, yielding 4 risk-status-by-EC groups, where at-risk higher EC children were termed the resilient group. Proximal household enrichment (e.g., exposure to learning materials, varied enriching experiences, academic and language stimulation, parental responsivity) distinguished the resilient group from lower performing children of similar risk status, whereas distal financial resources and proximal social network resources did not distinguish these two groups. Results suggest potential intervention targets to promote optimal EC development, particularly among children at risk. 相似文献

ABSTRACTDeformation bands, especially shear bands were intentionally formed in supersaturated Cu-4 at.% Ti alloy by groove-rolling with 75% area reduction. Cold deformation prior to the ageing process changed the precipitation behaviour of the alloy. The deformed structure with shear bands was maintained, without showing recovery and recrystallisation, even after prolonged ageing at 450°C for more than one day. The thermally stable shear bands act as nucleation initiation sites and prevent the expansion of discontinuous cellular precipitates. The hardness reached a value of 305?Hv and an electrical conductivity of 15% IACS (IACS?=?International Annealed Copper Standard. 100% IACS is defined as the conductivity corresponding to a volume resistivity at 20°C of 17.241?nΩ), compared to 283?Hv and 13% IACS for conventional solid-solutioned and peak-hardened alloy. In addition, the ageing time to reach the highest hardness was shortened from 720 to 180?min at 450°C. 相似文献

Subjective Well-Being and Hedonic Editing: How Happy People Maximize Joint Outcomes of Loss and Gain
Hedonic editing refers to the decision strategy of arranging multiple events in time to maximize hedonic outcomes (Thaler in Market Sci 4:199–214, 1985). The present research investigated the relationship between subjective well-being and hedonic editing. In Study 1, we gave participants pairs of social or financial events and asked them to indicate their preferences regarding the sequence and interval length between the two events. Compared to participants with lower subjective well-being, those with higher subjective well-being preferred to experience a social gain (e.g., chatting with a close friend) temporally closer to a financial loss, suggesting that happy individuals are more inclined than less happy individuals to use positive social events as cross-domain buffers against loss. In Study 2, participants were asked to select the type of positive event they would want to experience after a negative event. Happy individuals displayed a stronger preference for social events. Implications and directions for future research are discussed. 相似文献

This research extends previous work by demonstrating how the relationships between social cognition and exercise are influenced by different personality types. The theory of planned behaviour forms the basis of our theoretical model, and the Big Five personality framework was used to determine personality types. Data were collected from a quota sample of 512 Malaysian adults. The results suggest that an individual's personality can prevent him or her from exercising. For example, an extrovert is likely to be driven by affect and self‐confidence in their capability to exercise, and thus are more likely to participate in exercise. Those who are more conscientious (and less neurotic) feel more in control and thus possess a greater ability to exercise in comparison with their less conscientious and more neurotic counterparts. Our findings demonstrate the importance of considering personality factors in exercise research and caution us about underestimating the relationship between perceived control, attitude and its potential behavioural outcomes that could lead to a misinterpretation of its true impact. Our core contribution lies in identifying the underlying causes of social cognition differences in a moderating capacity, which has potential to yield important theoretical and practical implications. This study sets the ground for social marketers to improve their understanding of exercise behaviour and, in turn, consumer welfare. Ultimately, they could be in a better position to develop effective health intervention and educational programmes. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

In simple dynamic events we can easily perceive not only motion, but also higher-level properties such as causality, as when we see one object collide with another. Several researchers have suggested that such causal perception is an automatic and stimulus-driven process, sensitive only to particular sorts of visual information, and a major research project has been to uncover the nature of these visual cues. Here, rather than investigating what information affects causal perception, we instead explore the temporal dynamics of when certain types of information are used. Surprisingly, we find that certain visual events can determine whether we perceive a collision in an ambiguous situation even when those events occur after the moment of potential 'impact' in the putative collision has already passed. This illustrates a type of postdictive perception: our conscious perception of the world is not an instantaneous moment-by-moment construction, but rather is formed by integrating information presented within short temporal windows, so that new information which is obtained can influence the immediate past in our conscious awareness. Such effects have been previously demonstrated for low-level motion phenomena, but the present results demonstrate that postdictive processes can influence higher-level event perception. These findings help to characterize not only the 'rules' of causal perception, but also the temporal dynamics of how and when those rules operate. 相似文献

Daily dairies, also known as experience sampling methods (ESM) or everyday experience methods, are a common methodology utilized
to provide insight into momentary psychological processes. Traditionally, such studies often have utilized paper-and-pencil
surveys administered several times each day over a span of several days or weeks. However, advances in technology now allow
these studies to be conducted using palmtop computers (i.e., personal digital assistants; PDAs). Three software packages for
running these studies on the Palm operating system were explored and compared on a number of features. Specifically, ESP (Experience
Sampling Program, by Feldman Barrett & Barrett, 2001), iESP Version 3.2 (Intel Experience Sampling Program, by Intel Research
Seattle & the University of Washington Computer Science and Engineering Department), and PMAT Version 2.0 (Purdue Momentary
Assessment Tool, by the Military Family Research Institute at Purdue University) were examined, with their key features compared.
These advances in software for running diary studies include a number of features that provide researchers with methods and
information previously unavailable in diary studies and may expand the range of possibilities in diary study designs. 相似文献
