An apparent reason is that dependent variables and covariates need to be measured cholesterol medication comparison chart buy ezetimibe 10 mg lowest price. But a subtler reason is that measurement of an individual construct versus its manipulation can be viewed as two sides of the same coin. Understanding measurement error is central to any research design including experimental designs used in consumer psychology. The premise of this chapter is that understanding the measurement of one thing is central to understanding the measurement and manipulation of many things and, in fact, the entire research design. There is much to be learnt across different paradigms in research that often develop in relative independence, such as between research traditions in measurement, experimental designs and survey designs. Along these lines, the purpose of this chapter is to highlight the central importance of measurement in experimental research in consumer psychology. The topics of measurement and experimental design have been written about extensively (Nunnally, 1978; Cook & Campbell, 1979; Aronson, Carlsmith, Ellsworth, & Gonzales. This chapter offers a different perspective on merging insights from both perspectives to gain new insights on experimental designs. The chapter aims to provide depth of understanding of issues of measurement in experimental design in consumer psychology. Although survey designs are common in consumer psychology, measurement issues in survey design in consumer psychology are not in focus here. Moreover, the discussion of experimental designs also covers the measurement of the dependent variables. The chapter is written assuming basic knowledge of measurement and experimental designs. It borrows heavily from a recent book on measurement error and research design (Viswanathan, 2005). The second section uses issues in measure development, assessment and usage to derive implications for designing experiments in consumer psychology. The third section translates a finer taxonomy of types of measurement error to errors in an experimental context. The fourth section draws some broader parallels between measurement and research designs. As an example, in a study of time constraints and price judgments (Suri & Monroe, 2003), a series of pretests were used to decide on product categories, brand names, and high and low price levels. The time pressure manipulation was designed by first determining average time to process information. Then, different time pressure conditions were created based on absolute time using average time as a baseline. Respondents were assigned to different conditions and shown a monitor with the average time to complete the task and the time allotted to them. Each time pressure condition was assessed through determining responses to items tapping into subjective time pressure. In a study of gender typed ads and impression formation (Johar Moreau, & Schwarz, 2003), respondents completed a scale on tendency to gender stereotype in a first session. Two weeks later, in a second session of seemingly unrelated tasks, respondents rated ads, which were then followed by the experimenter leaving the room and a different experimenter administering the second task, and rating a woman based on an ambiguous description. Ads were selected from 2 weeks of television programming, identifying ads that showed women as homemakers and ads as controls in similar product categories. A large set of ads were pretested to identify a smaller set in both conditions that was similar on variables such as familiarity and liking.

The primary means of communication among neurons is generally taken as the firing rate of the neuron cholesterol levels range buy ezetimibe 10mg. Electrodes inserted into the brain can record these electrical impulses from single neurons cholesterol levels for diabetes order 10mg ezetimibe amex, groups of neurons cholesterol medication and viagra discount ezetimibe 10 mg mastercard, or from entire population responses percent of cholesterol in shrimp generic ezetimibe 10mg amex. Moreover, just as electrodes can record brain electrical activity, electrodes can also deliver electrical stimulation to neurons simulating aspects of neural firing. These latter two approaches make it possible to test causal hypotheses about neural function by changing the inputs to neural tissue without damaging the brain. The ability to rapidly generate action potentials within the neuron body is matched by a mechanism that assures rapid propagation of the electrical impulse through the axon so that neurotransmitters are released quickly after generation of an action potential. Since axons terminals and dendrites are not in direct contact, when a neuron fi res it releases its neurotransmitters in the synaptic cleft, a thin break between the cells about 20 nm wide. After the neurotransmitters bind to the receptors on the dendrites they are removed from the cleft by digestion by an enzyme, by being taken back into the neuron (reuptake), or by being broken down and rendered inactive (or the combination of the last two). Some receptors also initiate a sequence of chemical changes within the cell, which may further regulate ion inflow. Moreover, iontophoretic application of neurotransmitter agonist or antagonists can increase or decrease specific neurotransmitter effects in particular brain areas (Williams & Goldman-Rakic, 1995) allowing causal tests of hypotheses about neurotransmitter effects. When studying how neural activity is associated with behavior, social and cognitive neuroscientists typically study groups, or populations of neurons. Neighboring neurons tend to respond to the same or similar stimuli and to connect to the similar neurons or sets of neurons forming networks. When these groups are interconnected or have convergent or divergent connections, they are said to form neural circuits. Brain atlases such as the Talairach and Tournoux (1988) standard allow neuroscientists to use gross anatomical landmarks (such as bumps and turns in gyri or sulci-ridges and valleys) to identify specific anatomical regions. Such anatomical regions have been traditionally assumed to have specific functions. For example, damage to the frontal gyrus (inferior frontal) was identified by Broca (1861) as producing a loss of expressive language function or aphasia. However, in recent years there has also been an attempt to identify "functional" regions of the brain. Functional regions are identified by using a neuroimaging method that registers changes in neural processing during a specific task. So called "localizer tasks" can identify brain regions that respond to a particular kind of stimulus or psychological process such as preferential responses to faces relative to other body parts or objects. A major advance in cognitive and social neuroscience comes from being able to identify patterns of brain activity with anatomical regions whether these regions are defined by purely anatomical criteria or functional criteria. At the same time, there has been a substantial shift in research from studying single brain regions associated with specific psychological functions to identifying complex networks associated with these processes. In order to understand these networks it is necessary to understand the general structure of the brain. Understanding how these regions are organized is important to understanding the results of cognitive and social neuroscience research. The next section provides a thumbnail sketch of the overall organization of the anatomical regions of the brain most relevant to understanding neuroeconomics research. The Big Brain Picture-Cortical and Subcortical Parts There are a number of different ways that neuroscience research describes the landscape of the brain. Given the assumption of some relationship between function and structure, it is important to be able to identify which parts of the brain are involved (active) during different kinds of psychological processing. In order to refer to different parts of the brain, a number of different taxonomic schemes are used in research, with different strengths and weaknesses. However, it is important to be able to recognize which scheme is being used and to have some idea of how to interpret the intended reference. Brodmann (1909) numbered brain areas according to cellular composition (cytoarchitecture) and this numbering scheme is still widely used to identify different brain regions, although there have been criticisms raised of this work. For example, Brodmann area 4 refers to primary motor cortex and 22 to a part of the superior temporal gyrus.

You might feel pride at your skill (particularly if others in your group did less well in similar negotiations) cholesterol eating eggs order ezetimibe 10mg otc, but you also may experience guilt healthy cholesterol foods buy ezetimibe 10 mg low price. Russell and Carroll (1999a) argue that the bipolarity of emotional experience implies that when you are happy cholesterol levels vary proven ezetimibe 10mg, you are not sad cholesterol medication birth defects 10mg ezetimibe visa, just as when you are hot, you are not cold. Strictly speaking, that claim is very strong since being at one point on the abscissa of an affect distribution precludes being at any other point. Mutual exclusivity of positive and negative affect, on the other hand, would produce intermediate degrees of independence. But does any level of correlation between measures of positive and negative affect imply that any (even low) levels of happiness preclude experiencing sadness? Watson and Tellegen (1999) maintained that sadness decreases as happiness increases. In that sense, happiness and sadness regularly co-occur and are only mutually exclusive when people are maximally happy or maximally sad. Williams and Aaker (2002) employed either happy, sad, or mixed emotional appeals by combining the same picture with different characterizations of it. They found that the acceptance of the duality of emotions (via mixed emotional appeals) was greater among Asian American than Anglo Americans (who actually reported discomfort), although both groups reported experiencing a combination of happiness and sadness when given the mixed emotional appeal. Such self reports are ambiguous since it is difficult to know whether people assume they should be experiencing mixed emotions when confronted with a stimulus presenting a happy and sad event or could be translating their "somewhat sad" (or somewhat happy) feelings on to scales that allow them to report mixed emotions. Since people may well have alternated back and forth, in a subsequent study, Larsen et al. A button-pressing task suggested that people, in fact, experienced mixed emotions simultaneously. Note, however, that these are unlikely to be extremely positive and extremely negative feelings-a combination that seems difficult to imagine. So, another possibility is that people subjectively interpreted these more moderate feelings as though they were part positive and part negative in light of the information they were given. Andrade and Cohen (2007b) point out that previous theories tended to rely on the assumption that positive and negative feelings cannot be experienced at the same time. As a result, people who deliberately exposed themselves to apparent sources of negative feelings either do not experience much negative affect (Fenz & Epstein, 1967; Zuckerman, 1996) or focus on its relieving consequences-after removal of the aversive stimuli (Solomon & Corbit, 1974; Zillmann, 1980). Andrade and Cohen showed the importance of relaxing the single affective valence assumption in order to provide a more complete understanding of the phenomenon. However, fear approach consumers also showed increased levels of positive affect, whereas fear avoidance consumers showed no signs of positive experiences. Also importantly, the authors demonstrated that mixed feelings are more likely when individuals are able to place themselves within a protective (detachment) frame: "An ideal detachment frame gives people the ability to increase psychological distance from the main actors of the movie, while still absorbing the impact of the scenes" (p. People tend to deliberately choose to expose themselves to sources of negative affect when a psychological protective frame is present, as it allows for the co-activation of positive and negative affect. A similar rationale has been adopted to show the presence of mixed feelings of disgust and amusement as a result of video exposure (Hemenover & Schimmack, 2004). Integral affect refers to affective responses that are genuinely experienced and directly linked to the object of judgment or decision. These affective responses are integral to the extent that they are elicited by features of the object, whether these features are real, perceived, or only imagined. Incidental affect refers to affective experiences whose source is clearly unconnected to the object to be evaluated. It refers to affective responses that are elicited by the task or process of making judgments and decisions, as opposed to direct, integral responses to features of the target objects or purely incidental feelings. For example, the emotional stress of having to choose between two very attractive offers would be considered task-induced in that it is the process of having to choose between these two offers that is stressful, not the offers themselves. Indeed, decisions may trigger unpleasant task-related affect even when the options are associated with pleasant integral affect, for example, a choice between two vacation destinations. In the above example, the emotional stress experienced would not be incidental either because, by definition, it would not have arisen had a judgment or decision not been required. Each type of affect will be discussed separately in relation to consumer judgment and decision making. In general, though not always, objects that elicit pleasant feelings, such as a beautiful symphony, a sweet dessert, or an attractive singer, are evaluated more favorably, and objects that elicit unpleasant feelings, such as a noisy apartment, a sour tasting dish or a rude salesperson, are evaluated less favorably.

For consumer behavior cholesterol test equipment generic ezetimibe 10mg overnight delivery, the important implication is that purchasing impulses are in fact almost always resistible cholesterol levels defined purchase 10 mg ezetimibe fast delivery. A model of self-regulation from the health domain (Rothman cholesterol medication dizziness quality ezetimibe 10 mg, 2000) describes the desire to initiate a behavioral change as stemming from the positivity of the outcome cholesterol medication weight loss cheap 10mg ezetimibe free shipping. Thus, most people believe that smoking cigarettes is bad for them, and many have quit smoking in order to improve their odds of avoiding lung cancer in later life, but others may not value that outcome. Motivation may come from perceptions of the difficulty (or possibility) that the goal can be attained. This model emphasizes selfefficacy as key to whether and how the consumer will approach the self-control task. Thus, if a person considering a diet thinks, "If I am offered cake at parties, I am confident that I can refuse and instead I eat fruit," he or she is displaying self-efficacy and its aid in selecting suitable means to attain the larger goal of limiting caloric intake. Research on the overconsumption of food (binge eating) supports the importance of self-beliefs in motivating people to self-regulate-as well as the demotivating effects of not believing in oneself. This research shows that women who hold high standards for thinness but believe that they are overweight have high binge eating tendencies-but only if they also doubt their ability to reach their goal (Vohs et al. Women who believe that they close the gap between their current (perceived) body image and their desired body image do not overeat. Recent work suggests that laypersons have personal beliefs about how self-control operates (Mukhopadhyay & Johar, 2005). Moreover, personal theories about self-control can help predict variance in goal attainment, presumably because they influence commitment to self-regulatory goals and subsequent motivation. Breakdowns in the monitoring aspect of self-regulation are not as well understood as are breakdowns in the other ingredients, but nevertheless breakdowns in monitoring are a key reason that goals are not met. Monitoring is perhaps more central to understanding consumption than other aspects of goal attainment, which suggests that more work could be done to underscore its value in consumer behavior. Thus, if someone has money problems, it may be difficult to increase income or willpower, and revising standards downward (to accept being on the verge of bankruptcy) may be problematic. Likewise, it is no accident that successful dieters count calories and otherwise carefully monitor what they eat, and that the cessation of monitoring often undermines dietary efforts. This "extended-now" state renders people vulnerable to incoming urges and impulses and makes long-term goals seem less pressing. This extended-now theory of self-regulation is supported by studies showing that self-regulation changes time perception, such that self-regulators feel that time is moving more slowly as compared to non-regulators (and as compared to veridical durations). Classic work on chronic dieters demonstrates that not only the reliability or strength of the signal is important in monitoring, but also the interpretation of the feedback. Research on dieting versus nondieting1 shoppers shows that dieters buy less when they have not recently eaten than when they have recently eaten, whereas the opposite pattern holds with nondieters (Nisbett & Kanouse, 1969). The idea is that the bodily signals that one has not eaten in a while is a positive, reinforcing signal that the goal of limiting caloric intake is being met. Therefore, dieters-who have the goal of restricting caloric intake-buy less food when they get feedback that they are meeting their dieting goals. As another example of how interpretation can undermine monitoring, Gilovich (1983) addressed the seeming paradox that many gamblers continue to gamble and even seem to remain optimistic, even though most lose more than they win, and, in fact, long-term net losses are almost guaranteed by the structure of the gambling system (by which, for example, the casino or indeed the state government must make a net profit, so it pays out less in winnings than it takes in). Accurate monitoring would have to reveal to gamblers that they had lost more often than won. But Gilovich (1990) found that gamblers discounted some losses as "near wins" and so felt encouraged despite losing. This can be done by looking back at how far one has come or how much more has to be done. A new study suggests that seeing how far one has come may be more effective in promoting self-regulation than how much more work is ahead. Nunes and Dreze (in press) gave loyalty cards to customers at a professional car wash. Some customers were given a card that required 10 car wash purchases before one free car wash was earned, whereas others were given a loyalty card that required 8 car wash purchases before the reward. However, those in the 10 car wash condition were given their card with two "free" stamps already affi xed to it, making the amount of effort needed to reach the goal equivalent. Perceptions of progress mattered, though-34% of customers fi lled their card and earned a free car wash in the 10 washes-but-2-free condition, whereas only 19% did in the 8 washes condition. Moreover, the goal gradient was steeper for those in the 10-but-2 condition, such that after receiving the loyalty card, they came to the car wash more often than did the 8 wash condition customers.
