Does message framing affect changes in behavioural intentions in people with psoriasis? A randomized exploratory study examining health risk communication

Message framing is important in health communication research to encourage behaviour change. Psoriasis, a long-term inflammatory skin condition, has additional comorbidities including high levels of anxiety and cardiovascular disease (CVD), making message framing particularly important. This experimental study aimed to: (1) identify whether health messages about psoriasis presented as either gain- or loss-framed were more effective for prompting changes in behavioural intentions (BI), (2) examine whether BI were driven by a desire to improve psoriasis or reduce CVD risk; (3) examine emotional reactions to message frame; and (4) examine predictors of BI. A two by two experiment examined the effects on BI of message frame (loss vs. gain) and message focus (psoriasis symptom reduction vs. CVD risk reduction). Participants with psoriasis (n = 217) were randomly allocated to one of four evidence-based health messages related to either smoking, alcohol, diet or physical activity, using an online questionnaire. BI was the primary outcome. Analysis of variance tests and hierarchical multiple regression analyses were conducted. A significant frame by focus interaction was found for BI to reduce alcohol intake (p = .023); loss-framed messages were more effective for CVD risk reduction information, whilst gain-framed messages were more effective for psoriasis symptom reduction information. Message framing effects were not found for BI for increased physical activity and improving diet. High CVD risk was a significant predictor of increased BI for both alcohol reduction (β = .290, p < .01) and increased physical activity (β = ?.231, p < .001). Message framing may be an important factor to consider depending on the health benefit emphasised (disease symptom reduction or CVD risk reduction) and patient-stated priorities. Condition-specific health messages in psoriasis populations may increase the likelihood of message effectiveness for alcohol reduction.     

Temporal preparation decreases perceptual latency: Evidence from a clock paradigm

A clock paradigm was employed to assess whether temporal preparation decreases the time to detect the onset of a stimulus—that is, perceptual latency. In four experiments participants watched a revolving clock hand while listening to soft or loud target tones under high or low temporal preparation. At the end of each trial, participants reported the clock hand position at the onset of the target tone. The deviation of the reported clock hand position from the actual position indexed perceptual latency. As expected, perceptual latency decreased with target tone intensity. Most importantly, however, greater temporal preparation decreased perceptual latency in all four experiments, especially for soft tones, which supports rather directly the idea that temporal preparation diminishes the duration of perceptual processing.     

Parent-like spokesperson for campaigning an anti-plastic straw movement to young adults: Is it effective?

Parental communication is still relatively meaningful in Asian families with hierarchical, vertical, and authoritative relationships. Meanwhile, children's pro-environmental behaviour in emerging Asian nations tends to be passive, leading to a need for intervention from the closest parties, often the parent, whose familial role in green communication has not been examined. This study uses social learning theory to examine the interplay of parent-like spokespeople and message appeals in affecting young adults' cognitive and emotional responses, which is expected to influence the ad liking and believability of green advertisements and switching intention to green products, such as eco-friendly straws. A laboratory experiment was conducted with 240 subjects. The results showed that the frame of a father-like figure conveying a hope appeal generated the greatest enthusiasm and argument quality for young adults. Mother-like figures speaking a fearful message frame were the best generator for young adults' anger and threat appraisal. Ad liking was significantly impacted only by a mother-like spokesperson who spoke a fearful appeal mediated by anger and a father-like spokesperson who delivered a hope appeal mediated by argument quality. Young adults' willingness to switch to eco-friendly straws was indirectly influenced by the interaction effect of a mother-like spokesperson and fear appeal type mediated by ad believability.     

Language and persuasion: A discursive psychological approach

Across the social sciences, there is a wealth of research on the role of language in persuasion in interpersonal communication. Most of these studies have been conducted in laboratories using experimental methods, have taken a social cognitive perspective, and have focused on the effects of particular linguistic practices on how persuasive messages are understood, processed, and ultimately complied with. By contrast, less attention has been paid to how language can be used to create sequential, interactional, and social obligations, in everyday interactions, like sales encounters or business negotiations, where persuasion occurs naturally and is built into the fabric of the conversation. In reviewing the former approach to studying language and persuasion, in this paper, I highlight several critical shortcomings. Then, I argue that, when studying naturally occurring persuasion-in-interaction, a discursive psychological approach is better suited for investigating and theorising the interactional structures underpinning persuasion and the role of language therein.     

A driving simulation study to investigate the information threshold of graphical variable message signs based on visual perception characteristics of drivers

Graphical variable message signs (VMSs) are infrastructure-based advanced traveler information systems widely used to provide drivers with real-time traffic condition information about a road section or area. However, there is a lack of research on the suitable volume of information to be shown on graphical VMSs. In practice, an overload of VMS information commonly exists, especially on China’s highways. Building on our earlier findings obtained through surveys and static cognitive experiments, this study introduces the use of dynamic simulation experiments to assess the influence of the volume of information (i.e., number of roads displayed) on graphical VMSs from the perspective of drivers’ visual perception characteristics. Thirty-two drivers participated in the driving simulation experiment and questionnaires. Five indexes, including legibility speed, legibility distance, legibility time, comprehension accuracy, and driver subjective scoring, were thoroughly analyzed to evaluate their relationships to different volumes of information (i.e., four, five, and six roads shown on a VMS). The results show that the legibility distance notably decreased with increasing volumes of information. The comprehension accuracy decreased significantly when the number of roads shown increased to six. The legibility speed, legibility time, and subjective scoring also deteriorated as the number of roads displayed on the VMS increased. The index scores were evaluated, in combination with the data of the drivers’ subjective scoring, data-based statistical analyses, and comprehensive evaluations using the TOPSIS method, to recommend that five is the recommended maximum number of roads to be shown on a graphical VMS. The results of this study support the goal of providing understandable and effective messages for drivers by addressing issues relating to how much information should be displayed on a VMS. These findings provide a basis for policy development to ensure consistent and practical designs of graphical VMSs on highways.     

Field testing anti-speeding messages

PurposeDetermine whether anti-speeding messages displayed on roadside variable message signage (VMS) influence drivers’ speed choice selections.MethodSpeed detection tubes were installed across a single carriageway 60 km/h limit road section at positions prior to, immediately after, and at a longer distance from VMS display of anti-speeding messages during study Week2. Bi-directional vehicle speed data were collected continuously during the week prior to VMS installation (Week1), throughout the week that the anti-speeding messages were displayed (Week2), and a post-display week (Week3).ResultsOf six separately measured locations, Week2 southbound mean speeds (facing signage) and percent of drivers/riders exceeding the signed speed limit were consistently below those recorded during Week1 for all time periods. Aggregated Week3 (post-VMS) southbound data for all time periods, showed consistent patterns for mean speed and percent of drivers exceeding the signed speed limit, being higher than in Week2 (VMS displayed) but lower than during Week1 (pre-VMS).DiscussionCompared with Week1, messages influenced aggregate driver speed selection during Week2, with a residual positive effect (slower speeds) in Week3. While all three messages had positive effects, differences occurred in relative effectiveness between daytime (school and non-school hours) and night-time periods. Separately disaggregated data revealed differential effects for the three messages.ConclusionsFindings demonstrated the value of implementing theoretically informed message content and provided evidence for the impact that roadside road safety messaging can have on driver speed selection.     

Phallic Integration and Male Identity Development

The analytic setting as well as the analyst's initial communications unavoidably exert influence that may be perceived by the patient as a sexually tinged intrusion, which evokes questions about what the analyst wants. Together with the asymmetry of the analytic relationship, these phenomena uncannily bring to life a repressed relationship between infant and adult in which analogous stimuli constitute enigmas for the child. The theoretical understanding of Jean Laplanche of such enigmatic transference in terms of “primal seduction” is reviewed and clinical material is provided to illustrate Laplanche's ideas. The discussion addresses “recentralized” and “decentralized” aspects of sexuality. Primal seduction is discussed as including not only intrusion, but also qualities of stimulation and trust.     

安全标志词语的风险等级对注意效应的调节作用

安全标志是一种传递潜在风险的方式,在安全管理中有重要地位。安全标志词语在安全标志中应用广泛。本文从新的视角研究安全标志词语的有效性,应用心理学中的线索-靶范式研究安全标志词语的风险等级对目标的注意效应的影响。实验结果发现,词语的风险等级显著调节注意返回抑制（inhibition of return, IOR）效应, 高风险词语相对于中、低风险词语能够减弱IOR效应;但词语的风险等级对IOR的调节作用受到靶子位置的影响,其中,靶子出现在左侧时调节作用显著,而靶子出现在右侧时调节作用不显著,这是由于风险引发的负性情绪刺激处理的偏侧优势产生的。本文为安全标志有效性相关研究提供了新的研究视角和心理学实验证据。     

Safety implications of co-locating road signs: A driving simulator investigation

BackgroundAs road complexity increases the requirement for number of road signs also increases, although the amount of road side space does not. One practical strategy to address this is to present multiple road signs on the same gantry (sign co-location). However, there is very little research on the safety implications of this practice.Method36 participants (mean age = 42.25 years, SD = 13.99, 18 females) completed three driving simulator scenarios, each scenario had a different sign co-location condition: no co-location, dual co-location and triple co-location. Each scenario presented similar information using direction signs, variable message signs and variable speed limit signs, under. Each drive included standard motorway driving (100 km/h speed zone) in free flow traffic and one emergency event where a lead vehicle suddenly braked. The scenario order was counterbalanced and the emergency event vehicle varied.ResultsOverall, there was no impact of co-locating signs on general driving performance. No significant difference was observed between conditions for reaction time and minimum headway in response to the emergency event. Participants were able to correctly choose their destination whether the signs were co-located or not.DiscussionFor the particular configuration of signs tested there is no evidence that co-location negatively impacts driving performance. However, there may be some implications for travel speed and the manner in which the emergency event is responded to. Future work should confirm the findings on real roads. These findings provided support for sign co-location as a practical and safe option for displaying multiple road signs in a confined area.     

描述性规范提升义务献血的意愿而非行为

描述性规范指大多数人的做法对他人态度和行为的影响。本研究试图利用描述性规范改变公众的义务献血意愿和行为。研究由两个相似实验组成。实验1发现描述性规范促进了被试义务献血的意愿, 但并没有影响实际献血行为; 实验2在实验1的基础上试图通过增加短信提醒来促进义务献血行为, 但是结果同样显示描述性规范促进了被试的献血意愿而非行为。本文对此原因进行了讨论。
