Problem focused coping: This involves attempts to take action to either reduce the demands of the stressor or to increase the resources available to manage it cheap 20 mg prednisolone with amex. Examples of problem focused coping include devising a revision plan and sticking to it order prednisolone 40 mg without prescription, setting an agenda for a busy day order 10 mg prednisolone overnight delivery, studying for extra qualiﬁcations to enable a career change and organizing counselling for a failing relationship. Emotion focused coping: This involves attempts to manage the emotions evoked by the stressful event. Examples of behavioural strategies include talking to friends about a problem, turning to drink or smoking more or getting distracted by shopping or watching a ﬁlm. Examples of cognitive strategies include denying the importance of the problem and trying to think about the problem in a positive way. Several factors have been shown to inﬂuence which coping strategy is used: Type of problem: Work problems seem to evoke more problem focused coping whereas health and relationship problems tend to evoke emotion focused coping (Vitaliano et al. Age: Children tend to use more problem focused coping strategies whereas emotion focused strategies seems to develop in adolescence (Compas et al. Gender: It is generally believed that women use more emotion focused coping and that men are more problem focused. For example, Stone and Neale (1984) considered coping with daily events and reported that men were more likely to direct action than women. However, Folkman and Lazarus (1980) and Hamilton and Fagot (1988) found no gender diﬀerences. In contrast they use more emotion focused coping if the problem is perceived as being out of their control (Lazarus and Folkman 1987). Available resources: Coping is inﬂuenced by external resources such as time, money, education, children, family and education (Terry 1994). Poor resources may make people feel that the stressor is less controllable by them resulting in a tendency not to use problem focused coping. Measuring coping The diﬀerent styles of coping have been operationalized in several measures which have described a range of speciﬁc coping strategies. The most commonly used measures are the Ways of Coping checklist (Folkman and Lazarus 1988) and Cope (Carver et al. The coping strategies described by these measures include the following: s Active coping (e. Some of these strategies are clearly problem focused coping such as active coping and planning. For example, positive reframing involves thinking about the problem in a diﬀerent way as a means to alter the emotional response to it. Some strategies can also be considered approach coping such as using emotional support and planning whereas others reﬂect a more avoidance coping style such as denial and substance use. Therefore eﬀective coping can be classiﬁed as that which reduces the stressor and minimizes the negative outcomes. In addition, recent research has shifted the emphasis away from just the absence of illness towards positive outcomes. Much research has addressed the impact of coping on the physiological and self-report dimensions of the stress response. Coping and the stress illness link: Some research indicates that coping styles may moderate the association between stress and illness. For some studies the outcome vari- able has been more psychological in its emphasis and has taken the form of well-being, psychological distress or adjustment. For example, Kneebone and Martin (2003) critic- ally reviewed the research exploring coping in carers of persons with dementia. They examined both cross-sectional and longitudinal studies and concluded that problem- solving and acceptance styles of coping seemed to be more eﬀective at reducing stress and distress. In a similar vein, research exploring coping with rheumatoid arthritis sug- gests that active and problem-solving coping are associated with better outcomes whereas passive avoidant coping is associated with poorer outcomes (Manne and Zautra 1992; Young 1992; Newman et al. Similarly, research exploring stress and psoriasis shows that avoidant coping is least useful (e. For example, Holahan and Moos (1986) examined the relationship between the use of avoidance coping, stress and symptoms such as stomach-ache and headaches. The results after one year showed that of those who had experienced stress, those who used avoidance coping had more symptoms than those who use more approach coping strategies. Coping and positive outcomes: Over recent years there has been an increasing recognition that stressful events such as life events and illness may not only result in negative outcomes but may also lead to some positive changes in people lives. This phenomenon has been given a range of names including stress related growth (Park et al. This ﬁnds reﬂection in Taylor’s cognitive adaptation theory (Taylor 1983) and is in line with a new movement called ‘positive psychology’ (Seligman and Csikszentmihalyi 2000). Although a new ﬁeld of study, research indicates that coping processes which involve ﬁnding meaning in the stressful event, positive reappraisal and problem focused coping are more associated with positive outcomes (Folkman and Moskowitz 2000). Coping is considered to moderate the stress/illness link and to impact upon the extent of the stressor. Much research has involved the description of the kinds of coping styles and strategies used by people and some studies suggest that some styles might be more eﬀective than others. Initially, it was deﬁned according to the number of friends that were available to the individual. However, this has been developed to include not only the number of friends supplying social support, but the satisfaction with this support (Sarason et al. Wills (1985) has deﬁned several types of social support: s esteem support, whereby other people increase one’s own self-esteem; s informational support, whereby other people are available to oﬀer advice; s social companionship, which involves support through activities; s instrumental support, which involves physical help.
This recognition process functions via special receptors that are not expressed in a clonal manner buy prednisolone 10 mg otc. Humoral buy generic prednisolone 5mg, Antibody-Dependent Effector Mechanisms The objectives of the immune response include: the inactivation (neutraliza- tion) and removal of foreign substances cheap prednisolone 10mg with mastercard, microorganisms, and viruses; the rejection of exogenous cells; and the prevention of proliferation of patho- logically altered cells (tumors). The systems and mechanisms involved in these effector functions are largely non-specific. Specific immune recognition by B and T cells directs these effector mechanisms to specific targets.

Opsonization involves the coating of such microbes with Fc-ex- pressing antibodies which facilitates their phagocytosis by granulocytes. Many cells, particularly phagocytes (and interestingly enough also some bac- teria like staphylococci), bear surface Fc receptors that interact with different Ig classes and subclasses. Mast cells and basophils bear IgE molecules, and 2 undergo a process of degranulation following interaction with allergens against which the IgE molecules are directed. It is made up of a co-operative network of plasma proteins and cellular receptors, and is largely charged with the following tasks: & Opsonization of infectious pathogens and other foreign substances, with the aim of more efficient pathogen elimination. Bound complement factors can: enhance the binding of microbes to phagocytozing cells; result in the activation of inflammatory cells; mediate chemotaxis; induce release of inflammatory mediators; direct bactericidal effects; and induce cell lysis (Fig. The pro- duction of a C3 convertase, which splits C3 into C3a and C3b, is common to both pathways. C3b degradation products are recognized by recep- tors on B lymphocytes; they stimulate the production of antibodies as well as pathogen phagocytosis. The cleavage products C3a and C4a are chemotactic in their action, and stimulate expression of adhesion molecules. Nomenclature: the components of the alternative pathway (or cascade) are desig- nated by capital letters (B, D, H, I; P for properdin), those of the classical pathway (or cascade) plus terminal lysis are designated by “C” and an Arabic numeral (1–9). Component fragments are designated by small letters, whereby the first fragment to be split off (usually of low molecular weight) is termed “a” (e. Molecules often group to form complexes; in their designations the indi- vidual components are lined up together and are usually topped by a line.

Over 20 proteins of the complement system have been identified to date, and are classified as either activation or control proteins. C3 is not only present in the largest amount, but also represents a central structure for complement activation.

Pentameric IgM represents a particularly efficient C activator since at least two Ig Fc components in close proximity are required for C1q binding and activation. During alternative activation of complement, the splitting of C3 occurs directly via the action of products derived from microorganisms, endotoxins, polysaccharides, or aggregated IgA. C3b, which is produced in both cases, is activated by the factors B and D, then itself acts as C3 convertase.

Some viruses can activate the complement system without the intervention of antibodies by virtue of their ability to directly bind C1q. Importantly, without a stringent control mechanism complement would be activated in an uncontrolled manner, resulting in the lysis of the hosts own cells (for instance erythrocytes). Complement Control Proteins The following regulatory proteins of the complement system have been character- ized to date: C1 inhibitor, prevents classic complement activation. This protein is lacking in patients suffering from paroxysmal nocturnal hemoglobinuria. This is a glycolipid anchored within the cell surface which prevents C9 from binding to the C5b-8 complex, thus protecting the cell from lysis. Those complement components with the most important biological effects include: & C3b, results in the opsonization of microorganisms and other antigens, either directly or in the form of immune complexes. C5a initi- ates the chemotactic recruitment of granulocytes and monocytes, promotes their aggregation, stimulates the oxidative processes, and promotes the re- lease of the thrombocyte activating factor. Immunological Tolerance & T-cell tolerance, as defined by a lack of immune reactivity can be due to a number of processes: Firstly, Negative selection in the thymus (referred to as deletion); secondly a simple lack of reactivity to antigen (self or nonself) as a result of the antigen having not been present in the secondary lymphoid organs in a sufficient quantity or for a sufficient amount of time; and thirdly an excessive stimulation of T-cells resulting from the ubiquitous presence of sufficient antigen resulting in T cell exhaustion. Finally, it may also be possible that Tcells can become temporarily “anergized” by partial or incom- plete antigen stimulation. As a general rule, self-reactive (autoimmune) B cells are not generally deleted by negative selection and can therefore be present in the periphery. Exceptions to this rule include B cells specific for membrane-bound self-determinants, some of which are deleted or aner- gized. B cells react promptly to antigens, even self-antigens, which are ar- ranged repetitively. However, they only react to soluble monomeric antigens if they additionally receive T cell help. Thus, B-cell non-reactivity largely results from a lack of patterned antigen presentation structures or as a result of T-cell tolerance.

Explicit memory tests include recall memory tests, recognition memory tests, and measures of relearning (also known as savings). Implicit memory refers to the influence of experience on behavior, even if the individual is not aware of those influences. Implicit memory is made up of procedural memory, classical conditioning effects, and priming. Priming refers both to the activation of knowledge and to the influence of that activation on behavior. An important characteristic of implicit memories is that they are frequently formed and used automatically, without much effort or awareness on our part. Sensory memory, including iconic and echoic memory, is a memory buffer that lasts only very briefly and then, unless it is attended to and passed on for more processing, is forgotten. Schemas are important in part because they help us encode and retrieve information by providing an organizational structure for it. The hippocampus is important in explicit memory, the cerebellum is important in implicit memory, and the amygdala is important in emotional memory. Evidence for the role of different brain structures in different types of memories comes in part from case studies of patients who suffer from amnesia. Cognitive biases are errors in memory or judgment that are caused by the inappropriate use of cognitive processes. These biases are caused by the overuse of schemas, the reliance on salient and cognitive accessible information, and the use of rule-of-thumb strategies known as heuristics. These biases include errors in source monitoring, the confirmation bias, functional fixedness, the misinformation effect, overconfidence, and counterfactual thinking. Understanding the potential cognitive errors we frequently make can help us make better decisions and engage in more appropriate behaviors. Summers, sparked an uproar during a presentation at an economic conference on women and minorities in the science and engineering workforce. During his talk, Summers proposed three reasons why there are so few women who have careers in math, physics, chemistry, and biology. One explanation was that it might be due to discrimination against women in these fields, and a second was that it might be a result of women‘s preference for raising families rather than for competing in academia. But Summers also argued that women might be less genetically capable of performing science and mathematics—that they may have less ―intrinsic aptitude‖ than do men. One of the conference participants, a biologist at the Massachusetts Institute of Technology, walked out on the talk, and other participants said that they were deeply offended. Summers replied that he was only putting forward hypotheses based on the scholarly work assembled for the conference, and that research has shown that genetics have been found to be very important in many domains, compared with environmental factors. As an example, he mentioned the psychological disorder of autism, which was once believed to be a result of parenting but is now known to be primarily genetic in origin. Many Harvard faculty members were appalled that a prominent person could even consider the possibility that mathematical skills were determined by genetics, and the controversy and protests that followed the speech led to first ever faculty vote for a motion expressing a ―lack of confidence‖ in a Harvard president. Summers resigned his position, in large part as a result of the controversy, in 2006 (Goldin,  Goldin, & Foulkes, 2005). The characteristic that is most defining of human beings as a species is that our large cerebral cortexes make us very, very smart. In this chapter we consider how psychologists conceptualize and measure human intelligence—the ability to think, to learn from experience, to solve problems, and to adapt to new situations. We‘ll consider whether intelligence involves a single ability or many different abilities, how we measure intelligence, what intelligence predicts, and Attributed to Charles Stangor Saylor. We‘ll also consider intelligence in terms of nature versus nurture and in terms of similarities versus differences among people. Intelligence is more strongly related than any other individual difference variable to successful educational, occupational, economic, and social outcomes. Scores on intelligence tests predict academic and military performance, as well as success in a wide variety of jobs (Ones, Viswesvaran, &  Dilchert, 2005; Schmidt & Hunter, 1998). At least some of this latter relationship may be due to the fact that people who are more intelligent are better able to predict and avoid accidents and to understand and follow  instructions from doctors or on drug labels. Although some specific personality traits, talents, and physical abilities are important for success in some jobs, intelligence predicts performance across all types of jobs. Our vast intelligence also allows us to have language, a system of communication that uses symbols in a regular way to create meaning. Language gives us the ability communicate our intelligence to others by talking, reading, and writing. As the psychologist Steven Pinker put it,  language is the “the jewel in the crown of cognition‖ (Pinker, 1994). Although other species have at least some ability to communicate, none of them have language. How Summers offended: Harvard president’s comments underscored the gender bias we’ve experienced.
