Mixing emotions: The use of humor in fear advertising

Fear is used to advertise many products, services, and causes such as antismoking, sunscreen usage, and safe driving. Past research indicates that high levels of fear tension arousal can prompt defensive responses in the audience, which, in turn, can reduce the persuasive effect of the ad. We show in two studies that humor can reduce these defensive responses and hence increase the persuasiveness of fear advertising. Specifically, we show that increasing the level of fear tension arousal decreases persuasion when humor is absent but increases persuasion when humor is present. Further, this interaction of humor and fear tension arousal is mediated by defensive responses related to message elaboration and vulnerability to threat. Our results suggest that the effectiveness of fear advertising can be increased by adding an element of humor to the ad. Copyright © 2012 John Wiley & Sons, Ltd.     

Anisotropic thermal properties of single-wall-carbon- nanotube-reinforced nanoceramics

Dense single-wall-carbon-nanotube-(SWCNT)-reinforced alumina nanocomposites have been fabricated by a novel spark-plasma-sintering technique. Anisotropic thermal properties have been found in carbon nanotube composites. The introduction of ropes of SWCNTs gives rise to a decrease in the transverse thermal diffusivity with increasing carbon nanotube content while it does not change the in-plane thermal diffusivity. This is scientifically interesting and technologically important for the development of materials for novel thermal barrier coatings.     

Personality Characteristics and Development of Psychopathology in Bipolar I and Borderline Personality Disorder Patients

The debate whether Bipolar Affective Disorder and Borderline Personality Disorder fall under the same spectrum or they represent separate categories has received much research attention. However, the question of their underlying psychological aetiology as well as their personality correlates has remained largely un-explored. The present study aims at gaining knowledge about and insights into these questions. The sample studied consists of 10 Bipolar I patients and 10 patients with Borderline Personality Disorder. Following a cross-sectional design, after determining the remitted phase of Bipolar I patients using Hamilton Depression Rating Scale and Young’s Mania Rating Scale, the Temperament and Character Inventory, Attachment Style Questionnaire, Defense Style Questionnaire and Rorschach Inkblot Test were administered individually by the researcher. Both group of patients showed features of immaturity and instability. A correlational analysis indicated the probable pathway of development of psychopathology. The parallels of the findings to Kernberg’s concept of borderline personality organization have been discussed.     

The influence of visual perception of self-motion on locomotor adaptation to unilateral limb loading

Self-perception of motion through visual stimulation may be important for adapting to locomotor conditions. Unilateral limb loading is a locomotor condition that can improve stability and reduce abnormal limb movement. In the present study, the authors investigated the effect of self-perception of motion through virtual reality (VR) on adaptation to unilateral limb loading. Healthy young adults, assigned to either a VR or a non-VR group, walked on a treadmill in the following 3 locomotor task periods--no load, loaded, and load removed. Subjects in the VR group viewed a virtual corridor during treadmill walking. Exposure to VR reduced cadence and muscle activity. During the loaded period, the swing time of the unloaded limb showed a larger increase in the VR group. When the load was removed, the swing time of the previously loaded limb and the stance time of the previously unloaded limb showed larger decrease and the swing time of the previously unloaded limb showed a smaller increase in the VR group. Lack of visual cues may cause the adoption of cautious strategies (higher muscle activity, shorter and more frequent steps, changes in the swing and stance times) when faced with situations that require adaptations. VR technology, providing such perceptual cues, has an important role in enhancing locomotor adaptation.     

Thinking styles and risky decision‐making: Further exploration of the affect–probability weighting link

People usually overweight small probabilities and underweight large probabilities leading to the familiar inverse S‐shaped weighting function. This research explores the link between affect and the structure of probability weighting from the perspective of thinking dispositions, a concept central to dual system theories of reasoning. The effects of affective priming and cognitive load on both probability weighting and the value function are also examined. The evidence suggests that thinking styles do have predictive implications for risky decision‐making. Participants with a more affective thinking style tend to be more risk‐seeking in small probability gambles. However, increasing access to the affective system by affective priming or cognitive load manipulations tend to reduce risk‐seeking behavior in small probability gambles as well as reduce risk averse behavior in large probability gambles. Previous research, manipulating the affective nature of lottery outcomes, found evidence for an increase in curvature (more overweighting of small probabilities and more underweighting of large probabilities) of the weighting function for affect‐rich outcomes, lending support to a hope‐and‐fear deconstruction of probability weighting. The present research suggests that increased anticipatory emotions characterized by the elevation of the weighting function (more overweighting at all probabilities) is also important and could sometimes be more significant than hope‐and‐fear in decision‐making under risk. An integrated approach incorporating the impact of affect on all three, the elevation and curvature of probability weighting as well as the curvature of the value function explains the empirical findings.

A generalized method of image analysis from an intercorrelation matrix which may be singular

Following the works of Guttman (1953) and Kaiser (1976), we show that the image and anti-image covariance matrices can be derived from a singular correlation matrix, by making use of the orthogonal projector and a weaker generalized inverse matrix.     

Fluctuation-driven first-order crystal to rotator phase transition

This article develops renormalization-group techniques to analyze the phase transition between the crystal and the rotator-V (Rv), phase in n-alkanes. An explicit free energy is constructed and it is verified that the unstable fixed point corresponds to a fluctuation-driven first-order crystal to Rv phase transition. Available experimental data are consistent with our model.     

Affective meanings of 1,469 Bengali concepts

This article provides semantic differential ratings of 1,469 concepts in Bengali, a language spoken by about 250 million individuals in eastern India and Bangladesh. These data were collected from 20 male and 20 female Calcutta respondents who rated stimuli on three culturally universal affective dimensions: evaluation–potency–activity (EPA). This study employs pan-respondent component analyses as a means of examining the respondents’ usage of the standard EPA scales. The pan-respondent component analyses indicate that some respondents used the rating scales in unexpected ways, recording their feelings about one component of concepts’ EPA with ratings on a scale intended to measure a different dimension. When scores were based only on respondents who used the scales appropriately, several interesting patterns were found. For respondents of both genders, potency scores have a curvilinear relation with evaluation, such that very good and very bad concepts are mostly seen as very potent, whereas evaluatively neutral concepts are seen as somewhat impotent or just slightly potent. A moderate linear correlation exists between activity and evaluation, and a modest positive relation exists between potency and activity. Gender correlations are high on evaluation, .93, but much lower for potency scores, with a correlation of .55, and even lower for activity, .30. In this article we examine several explanations for why scales denoting potency and activity were reinterpreted as indicating goodness by certain respondents, and consider the matter of including data collected from respondents who used scales in this way.     

Lay theories and consumer perceptions of dietary supplements

Consumers lack awareness and concern of potential adverse reactions, interactions, and inappropriate usage associated with dietary supplements. The lack of strict governmental regulation of supplements accompanied by consumers' lack of knowledge often results in them relying on ordinary lay (naïve) beliefs and theories when making supplement‐based decisions. We use an accessibility–diagnosticity framework to explore the impact of lay theories/beliefs on consumers' perceptions and judgments of dietary supplements. Two experiments prime two lay theories relevant to dietary supplement decision making: “less is more” (LIM: Study 1) and “no‐pain no‐gain” (NPNG: Study 2). Supplement form (single‐ vs. multi‐ingredient) is also manipulated in both studies, and Study 2 includes a Food and Drug Administration disclaimer intervention. Findings show that when a LIM lay theory is primed (Study 1), supplement form is a diagnostic cue. Specifically, consumers perceive that multi‐ingredient supplements possess more severe adverse side effects compared with single‐ingredient supplements. In the presence of an NPNG mindset (Study 2), supplement form was not diagnostic in the decision process, and a disclaimer intervention that draws attention to the lack of government regulation and testing of supplements was ineffective at influencing perceived side effect severity and attitude. The data confirm that lay theories impact dietary supplement decision making and that the observed effects are consistent with an accessibility–diagnosticity framework. Implications for public policy are also discussed.
