Emotional reactivity and blood pressure elevations: anxiety as a mediator

There is a strong link between emotional reactivity and hypertension, yet little research to date has examined mediators of this relationship. Ourstudy investigated the mediating roleof anxiety on the relationship between emotional reactivity and blood pressure elevations. Participants were226 hypertensive patients (93 men and 133 women, Mean age = 53.09, SD = 13.88 years), purposivelydrawn from the General Outpatient Department in University of Calabar Teaching Hospital, Calabar, , Nigeria. . Measures for data collection were Emotional Reactivity Scale, State Trait Anxiety Inventory, and the Mercury Sphygmomanometer. Hayes PROCESS macro for SPSS which uses a regression-based, path-analytical framework, was employed in analysing the data. Results showed that emotional reactivity was positively associated with blood pressure elevations. Anxiety was positively associated with blood pressure elevations. Anxiety also fully mediated the relationship between emotional reactivity and blood pressure elevations, even after adjusting for the control variables (e.g., age, family history of hypertension, and educational status). The finding suggests that being less emotionally reactive is associated with a decrease in disabling influences of anxiety, thereby contributing to lower levels of mean arterial blood pressure. The findings may be helpful in improving prevention, control and management of hypertension in healthcare.     

Poor emotional responsiveness in clinical hypertension: Reduced accuracy in the labelling and matching of emotional faces amongst individuals with hypertension and prehypertension

Psychological factors are known to play an important part in the origin of many medical conditions including hypertension. Recent studies have reported elevated blood pressure (even in the normal range of variation) to be associated with a reduced responsiveness to emotions or ‘emotional dampening’. Our aim was to assess emotional dampening in individuals with more extreme blood pressure levels including prehypertensives (N = 58) and hypertensives (N = 60) by comparing their emotion recognition ability with normotensives (N = 57). Participants completed novel facial emotion matching and facial emotion labelling tasks following blood pressure measurement and their accuracy of emotion recognition and average response times were compared. The normotensives demonstrated a significantly higher accuracy of emotion recognition than the prehypertensives and the hypertensives in labelling of facial emotions. This difference generalised to the task where two facial halves (upper & lower) had to be matched on the basis of emotions. In neither the labelling nor matching emotion conditions did the groups differ in their speed of emotion processing. Findings of the present study extend reports of ‘emotional dampening’ to hypertensives as well as to those at-risk for developing hypertension (i.e. prehypertensives) and have important implications for understanding the psychological component of such medical conditions as hypertension.

Culture and decision‐making: Investigating cultural variations in the East Asian and North American online decision‐making processes

Research in cross‐cultural psychology suggests that East Asians hold holistic thinking styles whereas North Americans hold analytic thinking styles. The present study examines the influence of cultural thinking styles on the online decision‐making processes for Hong Kong Chinese and European Canadians, with and without time constraints. We investigated the online decision‐making processes in terms of (1) information search speed, (2) quantity of information used, and (3) type of information used. Results show that, without time constraints, Hong Kong Chinese, compared to European Canadians, spent less time on decisions and parsed through information more efficiently, and Hong Kong Chinese attended to both important and less important information, whereas European Canadians selectively focused on important information. No cultural differences were found in the quantity of information used. When under time constraints, all cultural variations disappeared. The dynamics of cultural differences and similarities in decision‐making are discussed.     

Differences between informants about type a,anger, and social support and the relationship with blood pressure

Abstract

In a study on the influence of different natural environments on self-perception and that of significant others, behavioral manifestations of Type A, Anger, and Social Support were assessed. It was hypothesized that due to different environmental demands, participants will be perceived as displaying differences in Type A behavior, anger, and social support at home and at work. Participants were 45 university employees, constituting a convenience sample. Assessment included Type A Structured Interview scores of participants and questionnaire scores for Type A, anger, and social support of participants who were also evaluated by their spouses and work supervisors. Other risk factors for coronary heart disease (i.e., blood pressure, smoking, previous heart condition, being sedentary, and family history) and their relationships with Type A, anger, and social support were also examined.

Participants and spouses agreed significantly on all measures, whereas participants and work supervisors agreed only on Type A behavior. Spouses' and work supervisors' evaluations of the participants' behavior were not or only marginally associated. Multiple regression analysis showed that the level of disagreement between the different informants with respect to Type A and social support were associated with elevated blood pressure. These results suggest that the perception of Vpe A behavior, anger, and social support may be situationally determined.     

Effects of duration of wearing high-heeled shoes on plantar pressure

In the present study we investigated the effects of different durations of using high-heeled shoes on plantar pressure and gait. A questionnaire survey and dynamic plantar pressure measurements were performed in 20 control females and 117 females who had worn high-heeled shoes for a long time. According to the duration of using high-heeled shoes (as specified in the questionnaire), subjects were divided into a control group and five groups with different durations of use (i.e. <2 years, 2–5 years, 6–10 years, 11–20 years and >20 years). Parameters, including peak pressure, impulse and pressure duration, in different plantar regions were measured with the Footscan pressure plate. The 2–5 years group had smaller midfoot contact areas for both feet and higher subtalar joint mobility, while the 6–10 years group had larger midfoot contact areas for both feet and prolonged foot flat phase during gait. The peak pressure and impulse under the second and fourth metatarsus were increased with the prolonged wearing of high-heeled shoes, and the pressure and impulse under the midfoot were substantially reduced in the 2–5 years group. The findings suggest that long-term use of high-heeled shoes can induce changes in arch morphology: the longitudinal arch tends to be elevated within 2–5 years; the longitudinal arch tends to be flattened within 6–10 years; and the forefoot latitudinal arch tends to collapse in more than 20 years.     

Time and moral judgment

Do moral judgments hinge on the time available to render them? According to a recent dual-process model of moral judgment, moral dilemmas that engage emotional processes are likely to result in fast deontological gut reactions. In contrast, consequentialist responses that tot up lives saved and lost in response to such dilemmas would require cognitive control to override the initial response. Cognitive control, however, takes time. In two experiments, we manipulated the time available to arrive at moral judgments in two ways: by allotting a fixed short or large amount of time, and by nudging people to answer swiftly or to deliberate thoroughly. We found that faster responses indeed lead to more deontological responses among those moral dilemmas in which the killing of one to save many necessitates manhandling an innocent person and in which this action is depicted as a means to an end. Thus, our results are the first demonstration that inhibiting cognitive control through manipulations of time alters moral judgments.

The Need for Closure and the Spontaneous Use of Complex and Simple Cognitive Structures

Abstract

The authors performed 2 experiments that explored the causal role of need for closure in producing the use of simple structures. In particular, the authors gave the participants a cue that called for a complex or a simple solution on a cognitive complexity task. The authors created the participants' need for closure through the use of time pressure. The results of both experiments revealed that participants only generated complex solutions in the complex cue-no time pressure condition. The discussion is focused on the effects of need for closure in tasks calling for adaptive and spontaneous flexibility.     

Effects of anxiety on the execution of police arrest and self-defense skills

We investigated the effects of anxiety on the execution of police officers' arrest and self-defense skills. Police officers (n=13) performed three tasks in which they kicked, blocked, or restrained an opponent who attacked them with a rubber knife (low anxiety, LA) or a shock knife (high anxiety, HA) in a within-subject design. We analyzed performance (on a 5-point Likert scale), movement times, posture, and movement velocity and acceleration. Results revealed that performance was worse in the HA compared to the LA condition. Furthermore, analysis of full-body movement showed that under increased anxiety, police officers' performance contained characteristics of avoidance behavior, such as faster reactions (to reduce the time being exposed to the threat), leaning further backward (kick), and ducking down (block). In line with recent theoretical developments, it appears that under increased anxiety, police officers were less able to inhibit stimulus-driven processing (fear of getting hit) and enforce goal-directed processing (perform the skill as well as possible) leading to avoidance behavior and a decrease in performance.
