When a particular taste accompanies a drug that influences immune responses icd 9 code for erectile dysfunction due to medication discount sildalist 120mg fast delivery, the taste by itself may come to produce an immune response (Ader & Cohen, 1985). Working with an 11-month-old named Albert, Watson and Rosalie Rayner (1920; Harris, 1979) showed how specific fears might be conditioned. Watson and Rayner presented a white rat and, as Little Albert reached to touch it, struck a hammer against a steel bar just behind his head. What is more, five days later Albert showed generalization of his conditioned response by reacting with fear to a rabbit, a dog, and a sealskin coat, but not to dissimilar objects such as toys. After losing his professorship at Johns Hopkins University over an affair with Rayner (whom he later married), he became the J. There he used his knowledge of associative learning to conceive many successful campaigns, including one for Maxwell House that helped make the "coffee break" an American custom (Hunt, 1993). Some have wondered if each of us might not be a walking repository of conditioned emotions (see CloseUp: Trauma as Classical Conditioning on the next page). Might extinction procedures or even new conditioning help us change our unwanted responses to emotion-arousing stimuli? One patient, who for 30 years had feared going into an elevator alone, did just that. In Chapters 14 and 15 we will see more examples of how psychologists use behavioral techniques to treat emotional disorders and promote personal growth. Experiments with dogs reveal that, indeed, if a painful stimulus is sufficiently powerful, a single event is sometimes enough to traumatize the animal when it again faces the situation. Note, too, how her traumatic experience robbed her of the normally relaxing associations with such stimuli as home and bed. Still, when I go to bed at night-always with the bedroom light left on-the memory of them entering my room repeats itself endlessly. When I drive by our old apartment, or when I have to go into an empty house, my heart pounds and I sweat. I am afraid of strangers, especially men, and the more they resemble my attackers the more I fear them. My housemate shares many of my fears and is frightened when entering our new apartment. Eleven years later this woman could report-as do many trauma victims (Gluhoski & Wortman, 1996)-that her conditioned fears had mostly extinguished: the frequency and intensity of my fears have subsided. Still, I remain cautious about personal safety and occasionally have nightmares about my experience. But more important is my renewed ability to laugh, love, and trust-both old friends and new. Operant Conditioning 8: What is operant conditioning, and how does it differ from classical conditioning? To teach an elephant to walk on its hind legs or a child to say please, we must turn to another type of learning-operant conditioning. Classical conditioning and operant conditioning are both forms of associative learning, yet their difference is straightforward:;: operant conditioning a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher. It also involves respondent behavior-actions that are automatic responses to a stimulus (such as salivating in response to meat powder and later in response to a tone). Behavior that operates on the environment to produce rewarding or punishing stimuli is called operant behavior. We can therefore distinguish classical from operant conditioning by asking: Is the organism learning associations between events it does not control (classical conditioning)? Or is it learning associations between its behavior and resulting events (operant conditioning)? Skinner (19041990) was a college English major and an aspiring writer who, seeking a new direction, entered graduate school in psychology.

In his laboratories at the University of Chicago psychologist Heinrich Kluver is just beginning the first experimental studies of the hallucinogen mesacaline. Derived from the peyote cactus which had been used by indigenous Indians throughout the New World for thousands of years, mescaline had only recently been isolated and synthesized, and was rapidly capturing the attention of researchers in Germany. But before this "classic" hallucinogen was fully investigated, other newer ones were being developed. Elsewhere in Germany, Kotz and Merkel (1926) had just reported the chemical groundwork for the preparation of a new compound, phencyclidine. Chen and his colleagues at the Research Laboratories of Parke, Davis and Company in Detroit have just "discovered" phencyclidine and observed its anesthetic effectiveness in animals. That announcement added one more drug to the rapidly growing list of psychoactive compounds, both natural and synthetic, which affect behavior. Yet science was just beginning to dwelop techniques for studying the effects of drugs on behavior. That year witnessed the publication of a new journal, Psychopharmacologia, officially announcing the pursuit. Nonetheless, reports fromuserswho first experiment with and experience the drug effects (the street drug users) provide a rational basis for the questions which researchers must ultimately attempt to ask and answer. Similarly, present day studies of phencyclidine and its derivatives may be helped by examination of the patterns of use and intoxicationin contemporary nonmedical users. It is in this spirit that the following studies with phencyclidine and its derivative ketamine were conducted. While many psychoactive drugs can be easily classified as either stimulants, depressants, or hallucinogens, the arylcyclohexylamines defy convenient classifications as they appear to have mixed excitatory, sedative, cataleptoid-anesthetic, and hallucinatory properties. The major questions concerning the use of these compounds by man are: (1) Why do humans initiate use of arylcyclohexylamines? It will be presently seen that the psychological intoxication resulting from arylcyclohexylamines is a primary reason for their continued use. The nature and extent of thisintoxicationin several groups of contemporary users Will also be explored. Furthermore, it will be shown that the phenomenology of intoxication with these compounds warrants their classification as true hallucinogens. Cases of adverse reactions, unpleasant subjective experiences, poisoning, and prolonged psychoses are well known. There can also be a preoccupation with death or death-related thoughts (meditatio mortis) and this has been 120 the basis for numerous criminal defenses of diminished capacity (see "Phencyclidine, Criminal Behavior, and the Defense of Diminished Capacity," this volume). Nonetheless, users initially experiment with the drug primarily out of a curiosity about it and a desire to experience the anticipated drug effects of tranquilization, dissociation, and hallucinations. Independent of adverse reactions and even "schizophrenomimetic" or "psychotomimetic" effects, many users found the drug to have highly reinforcing properties. The effects can be interpreted as a state of intoxication with high reinforcement potential. These authors described the hypnagogic states as resembling pseudohallucinations wherein subjects "reported feeling as though they were in some specific setting and were able to describe it in detail. While the reports typically had reference to past events, they were expressed as though the experiences were taking place at the moment. As in dreams, multiple shifts occurred in the settings experienced by the subjects, sometimes in rapid succession" (p. Sometimes the subjects reported euphoria and feelings of inebriation: "When it occurred, the subjects would often smile vacuously and compare their feelings to those resulting from several Martinis" (p. Most users have difficulty in describing this intoxication and simply report a state of oblivion and fantasy. Perry (1975) summarizes some of the psychological effects of this state: the high continues for 4-6 hours, during which time the user often becomes very talkative, having sincere and sympathetic conversations, usually with others similarly intoxicated. This gradually develops into a state of mild depression as the high wears off; the person is irritable, feels isolated and sometimes paranoid. These users generally require 24-48 hours to completely return to what they consider normal (p. Many users find the experience a positive one and emphasize the rewarding aspects of the same symptoms that other users cite as negative. Recent studies of phencyclidine users are beginning to uncover an increased occurrence of these pleasurable and positive effects among those who continually self-administer the drug.

Across various occupations, some people view their work as a job, an unfulfilling but necessary way to make money. Others view their work as a career, an opportunity to advance from one position to a better position. The rest-those who view their work as a calling, a fulfilling and socially useful activity-report the highest satisfaction with their work and with their lives. Between the anxiety of being overwhelmed and stressed, and the apathy of being underwhelmed and bored, lies a zone in which people experience flow. Immersed in a project, they worked as if nothing else mattered, and then, when finished, they promptly forgot about it. The artists seemed driven less by the external rewards of producing art-money, praise, promotion-than by the intrinsic rewards of creating the work. It takes time to refocus mental concentration after the distraction of an e-mail or instant message. Thus, Microsoft is developing an attentional user interface that aims to "detect when users are available for communication, or when the user is in a state of flow" (Ullman, 2005). When the researchers beeped people at random intervals and asked them to report what they were doing and how much they were enjoying themselves, those who were vegetating usually reported little sense of flow and little satisfaction. People reported more positive feelings when interrupted while doing something active, something that engaged their skills, be it play or work. In industrialized nations, work has been changing, from farming to manufacturing to knowledge work. More and more work is outsourced to temporary employees and consultants who communicate electronically from virtual workplaces in remote locations. Will the psychological contract-the subjective sense of mutual obligations between workers and employers- become more or less trusting and secure? These are among the questions that fascinate psychologists who study work-related behavior. In Chapter 6, we encountered one of its subfields: human factors psychology, which explores how machines and environments can be optimally designed to fit human abilities. Personnel psychologists match people with jobs, by identifying and placing well-suited candidates. Organizational psychologists modify jobs and supervision in ways that boost morale and productivity. Personnel Psychology 13: How do personnel psychologists help organizations with employee selection, work placement, and performance appraisal? Psychologists can assist organizations at various stages of selecting and assessing employees. They may help identify needed job skills, decide upon selection methods, recruit and evaluate applicants, introduce and train new employees, and appraise their performance. After concluding that many of the hires were ill-matched to the demands of their new job, Tenopyr developed a new selection instrument: 1. She asked new applicants to respond to various questions (without as yet making any use of their responses). She identified the individual items on the earlier test that best predicted who would succeed. When his mother gave him a box of paints to cheer him up one day, he felt the darkness lift and his energy surge. Marry the strengths of people with the tasks of organizations and the result is often prosperity and profit. Any such trait, if matched with suitable work, can function as a strength (Buckingham, 2007).
