Behaviorism
be•hav•ior•ism (bi-hav'y?-riz'?m)
n.
A school of psychology that confines itself to the study of observable and quantifiable aspects of behavior and excludes subjective phenomena, such as emotions or motives. Also called behavioral psychology.
be•hav'ior•ist n.
be•hav'ior•is'tic adj.
A school of psychology which seeks to explain animal and human behavior entirely in terms of observable and measurable responses to environmental stimuli. Behaviorism was introduced (1913) by the American psychologist John B. Watson, who insisted that behavior is a physiological reaction to environmental stimuli. He rejected the exploration of mental processes as unscientific. The conditioned-reflex experiments of the Russian physiologist Ivan Pavlov and the American psychologist Edward Thorndike were central to the development of behaviorism. The American behaviorist B. F. Skinner contended that all but a few emotions were conditioned by habit, and could be learned or unlearned. The therapeutic system of behavior modification has emerged from behaviorist theory. Therapy intends to shape behavior through a variety of processes known as conditioning. Popular techniques include systematic desensitization, generally used on clients suffering from anxiety or fear of an object or situation, and aversive conditioning, employed in cases where a client wishes to be broken of an unhealthy habit (such as smoking or drug abuse). Other behavior therapies include systems of rewards or punishments, and modeling, in which the client views situations in which healthy behaviors are shown to lead to rewards.

behavioral science
n.
A scientific discipline, such as sociology, anthropology, or psychology, in which the actions and reactions of humans and animals are studied through observational and experimental methods.
Cognition
cog•ni•tion (kog-nish'?n)
n.
1. The mental process of knowing, including aspects such as awareness, perception, reasoning, and judgment.
2. That which comes to be known, as through perception, reasoning, or intuition; knowledge.
The term cognition is used in several different loosely related ways. In psychology it is used to refer to the mental processes of an individual, with particular relation to a view that argues that the mind has internal mental states (such as beliefs, desires and intentions) and can be understood in terms of information processing, especially when a lot of abstraction or concretization is involved, or processes such as involving knowledge, expertise or learning for example are at work. It is also used in a wider sense to mean the act of knowing or knowledge, and may be interpreted in a social or cultural sense to describe the emergent development of knowledge and concepts.
Cognition in mainstream psychology
The sort of mental processes described as cognitive are largely influenced by research which has successfully used this paradigm in the past. Consequently this description tends to apply to processes such as memory, attention, perception, action, problem solving and mental imagery. Traditionally emotion was not thought of as a cognitive process. This division is now regarded as largely artificial, and much research is currently being undertaken to examine the cognitive psychology of emotion; research also includes one's awareness of strategies and methods of cognition, known as metacognition.
Empirical research into cognition is usually scientific and quantitative, or involves creating models to describe or explain certain behaviors.
While few people would deny that cognitive processes are the responsibility of the brain, a cognitive theory will not necessarily make any reference to the brain or any other biological process (compare neurocognitive). It may purely describe behavior in terms of information flow or function. Relatively recent fields of study such as cognitive science and neuropsychology aim to bridge this gap, using cognitive paradigms to understand how the brain implements these information processing functions (see also cognitive neuroscience), or how pure information processing systems (e.g. computers) can simulate cognition (see also artificial intelligence). The branch of psychology which studies brain injury to infer normal cognitive function is called cognitive neuropsychology. The links of cognition to evolutionary demands are studied through the investigation of animal cognition.
The theoretical school of thought derived from the cognitive approach is often called cognitivism.
The phenomenal success of the cognitive approach can be seen by its current dominance as the core model in contemporary psychology (usurping behaviorism in the late 1950s).
Cognitive
cog•ni•tive (kog'ni-tiv)
adj.
1. Of, characterized by, involving, or relating to cognition.
2. Having a basis in or reducible to empirical factual knowledge.
Cognitive science
cognitive science
n.
The study of the nature of various mental tasks and the processes that enable them to be performed.
Cognitive science is usually defined as the scientific study either of mind or of intelligence. Practically every introduction to cognitive science also stresses that it is highly interdisciplinary; it is often said to consist of, take part in, and collaborate with psychology (especially cognitive psychology), artificial intelligence, linguistics and psycholinguistics, philosophy (especially philosophy of mind), neuroscience, logic, robotics, anthropology and biology (including biomechanics).
Cognitive psychology
cognitive psychology
n.
Cognitive psychology is a theoretical perspective that focuses on the realms of human perception, thought, and memory. It portrays learners as active processors of information&emdash;a metaphor borrowed from the computer world--and assigns critical roles to the knowledge and perspective students bring to their learning. What learners do to enrich information, in the view of cognitive psychology, determines the level of understanding they ultimately achieve.

Psychometric Properties
Validity
The term validity refers to the extent to which a questionnaire or inventory measures what it claims to evaluate. Any instrument has many different validities, depending on the inventory's specific purpose and varying with the procedure for assessing its validity. Several of the most popular ways for studying the validity of an instrument are: analyzing its content, relating scores on the instrument to scores on a criterion measure, and investigating the particular psychological characteristics or constructs evaluated by the instrument.
The various procedures for assessing validity are useful to the extent that they increase understanding of what an instrument is measuring, so the scores will represent more accurate information on which decisions can be based.
This table shows different types of validity with corresponding definitions. SalesDialogue's products are then reviewed according to each validity measure.
Validity Measures and Definitions
| Type of Validity | Definition |
| Criterion Validity | Relates the scores on an instrument to objective performance criteria |
| Face Validity | Refers to the degree to which the instrument appears to measure what it is alleged to evaluate |
| Content Validity | The extent to which the instrument covers all of the important aspects of what is being measured |
| Item Validity | The extent to which the individual items are appropriate and representative of a larger domain |
| Predictive Validity | The extent to which instrument scores predict future performance |
| Congruent Validity | The relationship of the scores on the instrument to another instrument thought to be in the same measurement arena |
| Construct Validity | The extent to which the instrument measures a theoretical construct or trait |
| Concurrent Validity | The correlation between what the instrument measures, and some other variable, measured within the same time interval |
Validity of SalesDialogue's Products
The construction of valid instruments is not a simple matter – it requires hours of pilot testing, data analysis and instrument refinement. Much time and effort has been expended in the development of our products.
i) Criterion Validity - In the research we have conducted, our products have demonstrated good Criterion Validity such that scores are related to demonstrated competencies and observable behaviors. The relationship is solid and positive, and it has been shown that higher scores are affiliated with superior sales performance. Specifically, there is a statistically significant difference between groups of superior sales performers and average sales people on all six of the sales components.
ii) Face Validity - Our products have appropriate Face Validity. An instrument is said to be face valid if it appears to be measuring what it claims to evaluate. The inventory items appear to be measuring relevant concepts, without of course, giving away how the items align with the scales.
iii) Content Validity - Content Validity refers to the degree that the instrument covers the important aspects of what is being measured. For example, to demonstrate the Content Validity of a sales instrument, the instrument would be given to a number of sales people to complete and they would subsequently be asked whether the report, as well as the individual inventory items, covered important aspects of sales and that the feedback report offered tips and suggestions to help them improve their performance. Based on feedback from three independent pilot studies conducted in 1999, 2000 and 2001, we are satisfied with the Content Validity of our products. We have also refined the instruments and the feedback reports to reflect participant input.
iv) Item Validity - Item Validity examines the appropriateness of each individual inventory item. The items are considered independently of the content to ensure they are culture-free and denote the same meaning for different individuals. As you know, inventory items should be clear and straightforward so respondents are able to accurately and meaningfully describe themselves on the instrument.
v) Predictive Validity - Since our products are primarily developmental, as opposed to evaluative, Predictive Validity is not of primary importance, provided that the instruments meet other validity criteria. To establish the Predictive Validity of our instruments, they would need to be administered to a random group of individuals whose behavior would be subsequently monitored over time. One would then look for correlations between their original thinking styles, as measured by SalesBOOSTER, and observable behaviors in the environment that were linked to these cognitive scales.
vi) Congruent Validity - Congruent Validity refers to the relationship of the scores on an instrument to another instrument thought to be in the same measurement arena. So, Congruent Validity relates to inter-test correlation. We have established the Congruent Validity of our instruments by comparing scores with other cognitive instruments. The observed inter-test correlation has ranged from 0.45 to 0.74. This is a good, solid inter-test correlation coefficient, given that the comparative instruments measure general thinking styles rather than cognitive sales competencies.
vii) Construct Validity - An estimation of Construct Validity is derived from the theory, reasoning, or logic on which the instrument is based. The designer of any instrument has a theoretical view that is expressed by the instrument and the measurement scales. In addition to reviewing these scales and the theoretical assumptions associated with them, it is useful to assess the practicality of the theory by looking at its ability to statistically discriminate between groups known to be more competent versus groups known to be less competent on the measure. At a very basic level, the score range of these two groups will serve to validate the power of the instrument and its Construct Validity. Our products have consistently demonstrated appropriate Construct Validity between groups of differing sales ability, as determined by candidates’ sales performance. The assumptions behind our scales are reasonable and consistent with cognitive behavioral models and effective thinking practices.
viii) Concurrent Validity - Concurrent Validity is the correlation between what the instrument measures and a criterion variable within the same time frame. Whereas Predictive Validity examines the instruments' track record over time, Concurrent Validity uses an immediate external measure in the here and now. Concurrent Validity is not always easy to measure, since immediate, objective feedback can be elusive. It is worthwhile, however, to identify concurrent criterion measures, as their immediacy can help identify instrument strengths and weaknesses. In reviewing our products, we compared individual component scale scores with those obtained on a multi-rater competency instrument where both instruments were completed in approximately the same timeframe. The Concurrent Validity of scores ranged from 0.55 to 0.69.
Reliability
While validity refers to the instrument measuring what it claims to evaluate, reliability refers to consistency over time. By definition, an instrument can be reliable without being valid, but it cannot be valid without being reliable. This is a very important distinction that the reader may want to think about for a couple of minutes.
It is important because on occasion, test publishers present the reliability of their instrument, leaving people to assume it is also valid. Some of the instruments we have seen in our psychology practice are indeed reliable (consistent over time) but they are not valid because they do not measure what they claim to evaluate. For example, suppose we administered a test of numerical ability to a group of sales applicants today and a week from today. We would see very similar results across the time span, indicating that the test was, indeed, very reliable. However, even though it has high reliability, it would not be a valid measure of sales ability because math proficiency is not likely related to sales skills.
Our products have demonstrated validity and are reliable measures over time. There is a second type of reliability related to internal consistency called split-half reliability that compares sub-sets of items within scales. Our products' split-half reliability coefficients are comparable to other well-designed instruments.
