Students' misconceptions about scientific phenomena can arise from at least two possible sources, the students' personal experience with those phenomena and things learned in the classroom. Misconceptions have been studied in a variety of science disciplines, but little attention has been given to the faulty models that students have for physiological processes. In this study 393 undergraduates...
1. The Vibrionaceae 1.1. A GENERAL DESCRIPTION The family Vibrionaceae (Domain Bacteria, Phylum Proteobacteria, Class Gammaproteobacteria) is comprised of mostly motile gram-negative chemoorganotrophs, possessing at least one polar flagellum (Farmer III and Janda, 2005; Thompson and Swings, 2006). Vibrios are facultative anaerobes, having both respiratory and fermentative metabolisms, and the m...
Physiological indicators of arousal have long been known to be sensitive to mental events such as positive and negative emotion, changes in attention and changes in workload. It has therefore been suggested that human physiology might be of use in the evaluation of software usability. To this, there are two main approaches or paradigms: (i) comparisons of physiological readings across periods o...
Everything that is new or uncommon raises a pleasure in the imagination, because it fills the soul with an agreeable surprise, gratifies its curiosity, and gives it an idea of which it was not before possessed. Abstract 4 ABSTRACT Background: Clinical findings indicate that touch massage has the ability to induce positive emotions and influence stress responses. However, little is known about m...
Physiological recordings were taken while 16 psychopaths (P), 16 nonpsychopaths (NP), and 16 "mixed" (M) 5s received an injection of saline, followed 15 min. later by an injection of adrenalin. Tonic skin conductance of Group NP was generally greater than that of Groups M and P, a difference that increased throughout the course of the experiment. There were no significant group differences in t...
Inadequate early caregiving has been associated with risks of stress-related psychological and physical illness over the life span. Dysregulated physiological stress responses may represent a mechanism linking early caregiving to health outcomes. This paper reviews evidence linking early caregiving to physiological responses that can increase vulnerability to stress-related illness. A number of...
Salinity stresses act as inhibitor factors of plant growth. They can change the physiological characteristics and limit the production of crops. Sodium nitroprusside (SNP) is a stable free radical which use as a signalling molecule in plants and participates in various plant’s physiological, biochemical and molecular processes and also in plant’s responses to environmental stresses. We investig...
introduction: the main objective of the present study was to investigate the effect of preceding pictorial stimulus on the emotional autonomic responses of the subsequent one. methods: to this effect, physiological signals, including electrocardiogram (ecg), pulse rate (pr), and galvanic skin response (gsr) were collected. as these signals have random and chaotic nature, nonlinear dynamics of t...
