The attitude expression of a man.

The attitude is an expression of a person. we study it In psychology, an attitude is an expression of favor or disfavor toward a person, place, thing, or event (the attitude object). Prominent psychologist Gordon Allport once described attitudes "the most distinctive and indispensable concept in contemporary social psychology."Attitude can be formed from a person's past and present. Key topics in the study of attitudes include attitude measurement, attitude change, consumer behavior, and attitude-behavior relationships.

Many measurements and scales are used to examine attitudes. Attitudes can be difficult to measure because measurement is arbitrary, meaning people have to give attitudes a scale to measure it against, and attitudes are ultimately a hypothetical construct that cannot be observed directly.

Following the explicit-implicit dichotomy, attitudes can be examined through direct and indirect measures.

Whether attitudes are explicit (i.e., deliberately formed) versus implicit (i.e., subconscious) has been a topic of considerable research. Research on implicit attitudes, which are generally unacknowledged or outside of awareness, uses sophisticated methods involving people's response times to stimuli to show that implicit attitudes exist (perhaps in tandem with explicit attitudes of the same object). Implicit and explicit attitudes seem to affect people's behavior, though in different ways. They tend not to be strongly associated with each other, although in some cases they are. The relationship between them is poorly understood.

Explicit measures tend to rely on self-reports or easily observed behaviors. These tend to involve bipolar scales (e.g., good-bad, favorable-unfavorable, support-oppose, etc.).Explicit measures can also be used by measuring the straightforward attribution of characteristics to nominate groups. Explicit attitudes that develop in response to recent information, automatic evaluation were thought to reflect mental associations through early socialisation experiences. Once formed, these associations are highly robust and resistant to change, as well as stable across both context and time. Hence the impact of contextual influences was assumed to be obfuscate assessment of a person's "true" and enduring evaluative disposition as well as limit the capacity to predict subsequent behavior. Likert scales and other self-reports are also commonly used.

Implicit measures are not consciously directed and are assumed to be automatic, which may make implicit measures more valid and reliable than explicit measures (such as self-reports). For example, people can be motivated such that they find it socially desirable to appear to have certain attitudes. An example of this is that people can hold implicit prejudicial attitudes, but express explicit attitudes that report little prejudice. Implicit measures help account for these situations and look at attitudes that a person may not be aware of or want to show. Implicit measures therefore usually rely on an indirect measure of attitude. For example, the Implicit Association Test (IAT) examines the strength between the target concept and an attribute element by considering the latency in which a person can examine two response keys when each has two meanings. With little time to carefully examine what the participant is doing they respond according to internal keys. This priming can show attitudes the person has about a particular object. People are often unwilling to provide responses perceived as socially undesirable and therefore tend to report what they think their attitudes should be rather than what they know them to be. More complicated still, people may not even be consciously aware that they hold biased attitudes. Over the past few decades, scientists have developed new measures to identify these unconscious biases.
