by properties intrinsic in the stimulus but by meanings that the stimulus has acquired for the responding organism through experience—for example, Pavlow's dog's salivary glands responding to the sound of a bell. Third is the instrumental stage, as exemplified by a chimpanzee knocking down a banana with a stick. Here the response is determined by the intrinsic properties of the things involved (banana stick, chimpanzee's neurosensory-muscular system), but a new element has been introduced into behaviour, namely, the exercise of control by the reacting organism over things in the external world. And, finally, there is the symbol stage. In which the configuration of behaviour involves nonintrinsic meanings.
The first two stages exhibit a characteristic of the evolution of all living things: a movement in the direction of making life more secure and enduring. In the first stage the organism distinguishes between the beneficial, the injurious, and the neutral, but it must come into direct contact with the object or event in question to do so. In the second stage the organism may react at a distance, as it were—that is, through an intermediate stimulus. The conditioned reflex brings signs into the life process; one thing or event may serve as an indication of something else—food, danger, and so forth. And, since anything can serve as a sign of anything else(a green triangle can mean food, sex, or an electric shock to the laboratory rat), the reactions of the organism are emancipated from the limitations that stage one imposes upon living things, namely, the intrinsic properties of things. The possibility of obtaining life-sustaining things and of avoiding life-destroying things is thus much enhanced, and the security and continuity of life are correspondingly increased.
Which of the following is TRUE of the first stage of the evolution of mind?
A.The living things are unable to distinguish the beneficial, the injurious, and the neutral.
B.It is not necessary for a living thing to come into contact with another thing.
C.The intrinsic properties of things are the limitations imposed upon the organisms.
D.The first stage is characterized by the contraction of the pupil under increased stimulation by light.

Eating is controlled by many factors, including appetite, food availability, family, peers, and cultural practices, and attempts at voluntary control. Dieting to a body weight leaner than needed for health is highly promoted by current fashion trends, sales campaigns for special foods, and in some activities and professions. Eating disorders involve serious disturbances in eating behaviour, such as extreme and unhealthy reduction of food intake or severe overeating, as well as feelings of distress or extreme concern about body shape or weight.
Eating disorders are not due to a failure of will or behaviour; rather, they are real, treatable medical illnesses in which certain maladaptive (适应不良的) patterns of eating take on a life of their own. The main types of eating disorders are anorexia nervosa (厌食症) and bulimia nervosa (暴食症). A third type, binge-eating (暴食行为) disorder, has been suggested but has not yet been approved as a formal psychiatric diagnosis. Eating disorders frequently develop during adolescence or early adulthood, but some reports indicate their onset can occur during childhood or later in adulthood.
Eating disorders frequently co-occur with other psychiatric disorders such as depression, substance abuse, and anxiety disorders. In addition, people who suffer from eating disorders can experience a wide range of physical health complications, including serious heart conditions and kidney failure which may lead to death. Recognition of eating disorders as real and treatable diseases, therefore, is critically important.
Females are much more likely than males to develop an eating disorder. Only an estimated 5 to 15 percent of people with anorexia or bulimia and an estimated 35 percent of those with binge-eating disorder are male.
Anorexia Nervosa
An estimated 0.5 to 3.7 percent of females suffer from anorexia nervosa in their lifetime. Symptoms of anorexia nervosa include:
resistance to maintaining body weight at or above a minimally normal weight tot age and height
intense fear of gaining weight or becoming fat, even though underweight
disturbance in the way in which one's body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of the current low body weight
infrequent or absent menstrual periods (in females who have reached puberty [青春期])
People with this disorder see themselves as overweight even though they are dangerously thin. The process of eating becomes an obsession. Unusual eating habits develop, such as avoiding food and meals, picking out a few foods and eating these in small quantities, or carefully weighing and portioning food. People with anorexia may repeatedly check their body weight, and many engage in other techniques to control their weight, such as intense and compulsive exercise, or purging by means of vomiting and abuse of laxatives, enemas, and diuretics. Girls with anorexia often experience a delayed onset of their first menstrual period.
Bulimia Nervosa
An estimated 1.1 percent to 4.2 percent of females have bulimia nervosa in their lifetime. Symptoms of bulimia nervosa include:
recurrent episodes of binge eating, characterized by eating an excessive amount of food within a discrete period of time and by a sense of lack of control over eating during the episode
recurrent inappropriate compensatory behaviour in order to prevent weight gain, such as self-induced vomiting or misuse of laxatives, diuretics, enemas, or other medications (purging); fasting; or excessive exercise
the binge eating and inappropriate compensatory behaviour both occur, on average, at least twice a week for 3 months
