Factors affecting consumers' trust in online product reviews

In this study, we apply the uncertainty reduction theory from communication to delineate the antecedents of consumers' trust in online product reviews. We test the competing effects of information content (argument quality) and social component (perceived background similarity) on consumers' trust in reviews. We also hypothesize that the strength of the effect is moderated by consumers' involvement. To test the hypotheses, we adopted a 2 × 2 × 2 repeated measures experimental design. The results show that both argument quality and perceived similarity contribute to increased trust but in varying degrees. The results provide mixed support to the moderating role of involvement. While argument quality played an important role in the high involvement mode, perceived similarity explained more variance in the low involvement mode. We discuss the implications of these results for both research and practice. Copyright © 2012 John Wiley & Sons, Ltd.     

Impulsivity partially mediates the relationship between BIS/BAS and risky health behaviors

Several theorists have suggested that impulsivity can be understood as a joint function of the behavioral approach (BAS) and behavioral inhibition systems (BIS). After resolving questions concerning the measurement of impulsivity and BAS, this study examined the relationships among risky health behaviors, impulsivity, BIS, and BAS. Utilizing a sample of undergraduates (N = 904), a structural model was tested in which BAS and BIS predicted impulsivity, which, in turn, predicted risky behavior. Fit indices were acceptable, but not good. A modified version of the model showed a statistically significant negative relationship between BAS and risky behaviors. However, the fit indices were not unequivocally supportive of the need to include that path. Overall, the data suggest that impulsivity is the joint result of countervailing motivational forces and that it partially or fully mediates the influence of BIS and BAS on risky health behavior.     

The Influence of Perceived Product Risk on Consumers’ e-Tailer Shopping Preference

Increasingly, retailers are combining Internet and store based operations to become “multi-channel” as they attempt to attract and retain customers. This study investigates how the type and level of perceived product risk (specifically economic and psychosocial risk) influence patronage preference for shopping from three types of e-tailers. The e-tailer formats studied are: pure play e-tailers (e.g., Overstock.com), value-oriented store based e-tailers (e.g., Wal-Mart.com), and prestigious store based e-tailers (e.g., Bloomingdales.com). The hypotheses, based upon prior research in the area of perceived product risk, show that type and level of risk do matter. Further, e-tailers linked with prestigious stores have an advantage over both other e-tailer types. Results also show an interaction between perceived product risk and the e-tail format. Based on samples from the Northeast and Southeast USA, the results are found to be similar in these diverse regions, improving the generalizability of the findings.     

Relationship of Type of Product, Shopping Orientations, and Demographics with Preference for Shopping on the Internet

This research examines whether (1) consumers' shopping orientations are significantly related to their preference for shopping online, (2) consumers' demographic characteristics are significantly related to preference for shopping online, (3) relationships of shopping orientation and demographic variables with purchase preferences on the Internet will vary by the type of products (i.e., search, experience, or credence). Deriving from the product classification theory, products are classified into four categories: search products, two types of experience products, and credence products. Data were collected through self-administered surveys from adult population in two metropolitan areas in the Southern United States. The findings significantly support the study's hypotheses that shopping orientations such as convenience and recreational shopper and demographic variables such as gender, education, and household income were significantly related to consumer's online purchase preference. The researchers' findings also confirm that the relationships of shopping orientation and demographic variables with purchase preference for shopping online significantly differ by product category. More specifically, convenience and recreational orientations were positively related to preference for shopping online for experience-1, experience-2, and credence product types, though the directional relationship between recreational shopper orientation and preference for shopping on the Internet was positive rather than negative as hypothesized. The results and discussion section also includes implications drawn from the findings.     

Stereotypes in social psychology: The “West-East“ differentiation as a reflection of western traditions of thought

Notwithstanding the fact that stereotypes and ethnocentrism constitute central topics of social psychology a cultural psychological question has almost been completely neglected in the discipline’s reflections on its own scientific endeavors: How has Western psychology’s construction of the “Indian“ and the “Eastern psyche“ been influenced by stereotypes that are embedded in culture-specific traditions of European scholarly and non-scholarly thinking? The problems tackled in this article are related to current social and cross-cultural psychological perspectives on the Indian context. In addition, they are related to social and cross-cultural psychological contributions to the well-established differentiation between the “West“ and the “East,“ which many psychologists have become used to and which are the foundation of current psychological theories about so-called “West-East differences.“     

Image representation,scaling and cognitive model of object perception

Neuropsychological investigations of visual imagery and representations have led to a deeper understanding of the spatial perception, representation and memory. But how each individual perceives object’s geometrical properties and how they differ from person to person, both under event-related memory and normal recollecting memory in the presence or in the absence of direct sensory stimulation is still unclear. Spatial knowledge is diverse, complex, and multi-modal, as are the situations in which it is used. All seem to agree that a cognitive map is a mental representation of an external environment. The image scaling is important in understanding the psychological dysfunctions of patients suffering from spatial cognition problems. The scaling becomes self-evident in art forms, when people are asked to draw image of objects they see actively or from their short or long term memory. In this paper we develop a comprehensive model of this scaling factor and its implications in spatial image representation and memory. We also extend its notion in understanding the perception of objects whose representations are normally not possible (like the perception of universal scales, infinities and parallel lines) but are well comprehended by the human brains. Here we give a scaling factor which is variable depending on the situations for a person based on his visual memory and drawing capabilities. And then extend it to analyse his cognitive strengths, disorders and any imperfections. This model also helps in formalizing the architectural cognitive maps needed to change the scaling factor, depending on the types of visual works one performs.     

The Persuasive Effects of Metaphor: A Meta‐Analysis

Empirical investigations of metaphor's persuasive effects have produced mixed results. In an effort to integrate the literature, we present a review and meta‐analytic summary of existing studies. Six explanations for the potential suasory advantage of metaphor over literal language were reviewed: (a) pleasure or relief, (b) communicator credibility, (c) reduced counterarguments, (d) resource‐matching, (e) stimulated elaboration, and (f) superior organization. Next, a meta‐analysis was conducted and the impact of seven moderator variables was tested. The overall effect for the metaphor‐literal comparison for attitude change was r = .07, which supported the claim that metaphors enhance persuasion. The effect rose to r = .42 under optimal conditions, when a single, nonextended metaphor was novel, had a familiar target, and was used early in a message. Metaphor appeared to exert a small effect on perceptions of source dynamism (r = .06), but showed no demonstrable impact on competence (r =?.01) or character (r =?.02). Of the six theories considered, the superior organization explanation of metaphor's persuasive impact was most supported by the results.     

Sexual Harassment in Educational Institutions in Delhi’ NCR (India): Level of Awareness,Perception and Experience

This study examined the level of awareness of sexual harassment in educational institutions in Delhi NCR (India). This paper grouped the results of all respondents into two categories, i.e. Private and State institutions, wherein a total number of 430 respondents were selected from ten private and state universities by simple random sampling from their respective law faculties. The statistical tools used in analyzing the data collected were frequency and chi square which revealed that the level of awareness of private or individually owned institutions is relatively high but lacks clarity, and boils down to a lower level of awareness as compared with state or government owned institutions. The findings also revealed that private universities experience sexual harassment just like state universities. Based on these results, the author recommends the augmentation of awareness programs in all universities, especially private ones. Compulsory sexual education courses for new intakes could be arranged, and final year students could also be re-oriented before they graduate.     

Simulated Visual Field Loss Does Not Alter Turning Coordination in Healthy Young Adults

Turning, while walking, is an important component of adaptive locomotion. Current hypotheses regarding the motor control of body segment coordination during turning suggest heavy influence of visual information. The authors aimed to examine whether visual field impairment (central loss or peripheral loss) affects body segment coordination during walking turns in healthy young adults. No significant differences in the onset time of segments or intersegment coordination were observed because of visual field occlusion. These results suggest that healthy young adults can use visual information obtained from central and peripheral visual fields interchangeably, pointing to flexibility of visuomotor control in healthy young adults. Further study in populations with chronic visual impairment and those with turning difficulties are warranted.
