Psychological factors affecting

To predict the comfort of a material, a combination of hand evaluation, eg, using the Kawabata system, as well as deterrnination of the heat and moisture transport properties, is necessary. Often, these values are correlated with a sensory evaluation of the tactile qualities of the material by a human subject panel. A thorough discussion of the many physical and psychological factors affecting comfort is available (134,135). 

In a full account of the relevant interactions it would therefore also be necessary to assess how psychological factors affect, and are affected by, processes in the nervous, endocrine and immune systems.

The paper by Chamberlin published under the title The Method of Multiple Working Hypotheses in 1890 (republished in 1965) is, however, historically interesting. There he described the dangers of affection for a favorite theory by making reference to psychological factors.

Pre-gastric factors can include the appearance of food, its taste and odour, learned preferences, aversions and psychological factors. Mental states such as fear, depression and social interactions can all affect food intake.

Erectile dysfunction (ED), the inability to achieve or maintain a penile erection sufficient to permit satisfactory sexual intercourse, is estimated to affect over 100 million men worldwide, with a prevalence of 39% in those of 40 years. Its numerous causes include cardiovascular disease, diabetes mellitus and other endocrine disorders, alcohol and substance abuse, and psychological factors (14%). While the evidence is not conclusive, drug therapy is thought to underlie 25% of cases, notably from antidepressants (SSRI and tricyclic), phenothiazines, cypro-terone acetate, fibrates, levodopa, histamine H -receptor blockers, phenytoin, carbamazepine, allopurinol, indomethacin, and possibly adrenoceptor blockers and thiazide diuretics. 

These are but a few of many studies and clinical findings that collectively provide strong support for the idea that environmental and psychological factors can significantly affect biologic and neurologic functioning. 

The importance of psychological factors in the pathogenesis of PUD remains controversial. Clinical observation suggests that ulcer patients are adversely affected by stressful life events. However, results from controlled trials are conflicting and have failed to document a cause-and-effect relationship. It is possible that emotional stress induces behavioral risks such as smoking and the use of NSAIDs, or alters the inflammatory response or resistance to HP infection. The role of stress and how it affects PUD is complex and probably mnlti-factorial. 

Reflexes such as the flexion reflex and the eye blink reflex are affected by psychological factors such as fear and arousal (Koh and Drummond 2006), and it is reasonable to assume that cough may also be influenced by these types of psychological factors. 

In the proposed model, exposure refers to the external factors (i.e., work requirements) that produce the internal dose (i.e., tissue loads and metabolic demands and factors). Workplace organization and hand tool design characteristics are examples of such external factors that can determine work postures and define loads on the affected tissues or velocity of muscular contractions. Dose is defined by a set of mechanical, physiological, or psychological factors that in some way disturb an internal state of the affected worker. Mechanical disturbance factors may include tissue forces and deformations produced as a result of exertion or movement of the body.

It is not uncommon for a person with an amputation to have two prostheses, one that emphasizes mechanical function, one for work, and an interchangeable one with a more humanlike appearance for social occasions, i.e., different tools for different jobs. Choice of prosthesis is ultimately based on many psychological, cultural, and practical factors. Other factors affecting the issue are age, gender, occupation, degree of physical activity, the amputee s attitude toward training, the type of amputation involved, and whether it is unilateral or bilateral limb loss. (Beasley and de Bese, 1990 Fillet and Mackin, 1992).
