Physiological basis of behaviour

Fat can store twice as many calories per unit weight than proteins are carbohydrates. Again it could be argued that this is of survival value. In the case of sleep, arousal levels generally seem lower than during waking; however, during one stage of sleep arousal levels appear highly similar to those in the waking state.

Presumably the life changes lead to increased stress, which in turn promotes an increased likelihood of illness. With a considerable loss of auditory sensitivity, some sounds may be perceived as distorted paracusis.

Cooking softens foods so that less damage is done to teeth during the chewing process. The theory argued, for example, that experiencing a dangerous event such as an automobile accident leads to bodily changes such as increased breathing and heart rate, increased adrenaline output, and so forth.

There are three major types of familial conflict: After more prolonged exposure, the outer and inner hair cells related to transmission of high-frequency sounds are missing.

That is, motivation can produce behaviours that lead to increases in future motivation. Instead, in species like the Edith's checkerspot butterfly, males' efforts are directed at acquisition of females and they exhibit indiscriminate mate location behavior, where, given the low cost of mistakes, they blindly attempt to mate both correctly with females and incorrectly with other objects.

In this sense, females can be much choosier than males because they have to bet on the resources provided by the males to ensure reproductive success. Many animals may even be especially conspicuous in escape e. However, there is little support for this theory.

Drive theory states that the more arousal and anxiety an individual experiences, the higher their performance will be.

However, it needs to be added that other studies such as Story et al found that wealthier children were generally happier with their body shape. The near-universal adoption of an LAeq,8h value of 85 dB or lower as the limit for unprotected occupational noise exposure, together with requirements for personal hearing protection, has made cases of severe unprotected exposures more rare.

Males of this species are limited in reproduction primarily by access to mates, so they claim a territory and wait for a female to pass through.

Introduction to Psychology/Biological basis of behavior

Finally, motivation is sometimes also approached from a more philosophical direction. Stronger, but temporary, reactions also occur when noise exposure is increased over time, in comparison to situations with constant noise exposure e.

These brood parasites selfishly exploit their hosts' parents and host offspring.

What Is the Physiological Basis of Behavior?

Unlike Hippocrates, Galen argued that humoral imbalances can be located in specific organs, including the entire body.

The fact that these genes exist and have been maintained within the population again provide powerful biological evidence for an adaptive preference for sweet foods.

The inverted-U function The relationship between changes in arousal and motivation is often expressed as an inverted-U function also known as the Yerkes-Dodson law. Cannon and a colleague, Philip Bard, proposed an alternative arousal theory, subsequently known as the Cannon-Bard theory.

Similarly, it is known that severing the vagus nervewhich causes stomach contractions to cease, does not eliminate the experience of hunger. Other researchers have suggested that bodily changes are unnecessary for the experience of emotional arousal and that the cognitive label alone is sufficient.

The ability to find these fruits quickly is an adaptive quality that has evolved outside of a mating context. Researchers then measured their total intake. Early research on this topic emphasized the essential equivalency of changes in arousal, changes in emotion, and changes in motivation.

Ethologists use naturalistic observation and field studies as their most common techniques. Each parent has a limited amount of parental investment over the course of their lifetime. In the reaction to snakes at least, notwithstanding Freudian explanations that they symbolize male sex organs, the behaviour of people may be compared with owl mobbing among passerine birds.

He would give the rats novel solutions to taste for example saccharin. Zeus had him tied to a rock in the Caucusus, where each day an eagle ate out his liver. At this stage we were still hunter-gatherers, out looking for food rather than growing and rearing our own supplies.

Psychological Basis of Human Behavior

Modern day hunter-gatherers such as the San of Namibia and Botswana, still acquire about 60% of their energy intake from meat and milk.

Here we are providing Organizational Behaviour Multiple choice questions with answers. These MCQs & answers can help to both students and teachers to understand concepts of organization behaviour.

Free radicals can be defined as molecules or molecular fragments containing one or more unpaired electrons in atomic or molecular orbitals (Halliwell & Gutteridge, ).This unpaired electron(s) usually gives a considerable degree of reactivity to the free radical.

Physiological psychology is a subdivision of behavioral neuroscience (biological psychology) that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments.


Physiological and behavioral effects of animal-assisted interventions on therapy dogs in pediatric oncology settings. Vision and other special senses. Pigs have colour vision and a panoramic range of about °, and binocular vision of 35–50°.

It is thought they have no accommodation (i.e., they cannot focus).
