Psychology For Dummies Cheat Sheet

The main question that fuels psychology is “Why do people do what they do?” Psychology basically aims to uncover what people do along with why and how they do it. Studying everyday behavior and mental processes is the focus of psychology much of the time. But sometimes the stresses of life can seem overwhelming, and in those cases people need help right away.

3 Psychological Tests to Measure Abnormal Behavior, Achievement, and Personality

Psychological tests are part of the entire psychological assessment process. Assessment is a set of scientific procedures used to measure and evaluate an individual’s behavior and mental processes. Psychologist Anne Anastasi (1908–2001), a past president of the American Psychological Association, defines a psychological test as an objective, standardized sample of behavior or mental processes. Nearly all topics in psychology can be measured with a test.

Clinical tests

Clinical psychologists (psychologists who work with mental disorders and abnormal behavior) typically use clinical testing as a way to clarify diagnoses and assess the scope and nature of a person’s or family’s disturbance and dysfunction. Specific tests are designed to assess the extent to which a patient may or may not be experiencing the symptoms of a particular disorder. These are diagnostic tests. Behavioral and adaptive functioning tests are two types of clinical tests that determine how well a person is doing in her everyday life and whether she exhibits specific problem behaviors. A common instrument used with children is the Child Behavior Checklist, which assesses the extent of a child’s behavior problems. Another commonly used clinical test is the Conner’s Parent Rating Scale, which detects attention deficit/hyperactivity disorder (ADHD) symptoms. In addition to disorder-specific inventories and tests, a wide variety of tests designed for other purposes lend themselves to the diagnostic process. Intelligence tests are designed to measure intelligence, but they can also show signs of cognitive dysfunction and learning disabilities. Personality tests are designed to measure personality, but they can also provide helpful insight to the types of psychological problems an individual is experiencing.

Educational and achievement tests

Educational and achievement tests measure an individual’s current level of academic competence. Glen Aylward, chair of the Division of Developmental and Behavioral Pediatrics at the Southern Illinois University School of Medicine, identifies three major purposes of this type of testing:
  • Identify students who need special instruction.

  • Identify the nature of a student’s difficulties in order to rule out learning disabilities.

  • Assist in educational planning and approach to instruction.

A typical educational/achievement test assesses the most common areas of school activity: reading, mathematics, spelling, and writing skills. Some tests include other areas such as science and social studies. A popular achievement test in use today is the Woodcock-Johnson Psychoeducational Battery, Revised. The test consists of nine subtests, measuring the standard areas of instruction but in more detail (mathematics is broken down into calculation and applied problems, for example). When a student has a hard time in school, it’s not unusual to administer an achievement test. Sometimes, students have a difficult time because they have a learning disability. Part of identifying a learning disability is assessing the student’s achievement level. Other times, a student struggles because of non-academic difficulties including emotional problems, substance abuse, or family issues. An achievement test sometimes helps to tease out these non-academic problems.

Personality tests

Personality tests measure many different things, not just personality. Numerous tests are designed to measure emotion, motivation, and interpersonal skills as well as specific aspects of personality, according to the given theory on which a test is based. Most personality tests are known as self-reports. With self-reports, the person answering questions about herself, typically in a pencil-and-paper format, provides the information. Personality tests are usually developed with a particular theory of personality in mind. A test may measure id, ego, or superego issues, for example, if it originates from a Freudian view of personality development.


Perhaps the most widely used personality test in the United States is the MMPI-2, The Minnesota Multiphasic Personality Inventory, 2nd Edition. Almost all American psychologists are trained to use the MMPI-2, which is considered to be a very reliable and valid instrument. A patient’s results from a MMPI-2 test provide rich information about the presence of psychopathology and level of severity, if present. The test’s results also reveal information about the emotional, behavioral, and social functioning of the test taker. A lot of psychologists use the MMPI-2 as a way to check the accuracy of their observations and diagnoses. The MMPI-2 test consists of 567 individual items and produces a score on nine clinical categories or scales. If a score is over a specific cutoff, it usually gets the attention of the psychologist administering the test. Psychologists consider such scores to be of clinical significance. The MMPI-2 covers a wide variety of areas, including depression, physical complaints, anger, social contact, anxiety, and energy level.

Projective personality tests

Projective personality tests are a unique breed of test. When most people think of psychological testing, these kinds of tests come readily to mind. The stereotype involves sitting across from a psychologist, looking at a card with smeared ink or a picture of somebody doing something on it, and answering questions like “What do you see here?” (You can take a free, mock personality test at

Projective personality tests are based on the projective hypothesis, which states that when presented with ambiguous stimuli, people project parts of themselves and their psychological functioning that they may not reveal if asked directly The idea is that many people can’t exactly describe what’s going on mentally and emotionally because of psychological defense mechanisms. Projective tests get past the defenses and penetrate the deep recesses of the psyche.

Perhaps the most popular projective personality test and maybe even the most popular psychological test of all time is the Rorschach Inkblot Test (RIT). The RIT consists of ten cards, each with its own standard inkblot figure. None of these inkblots are a picture or representation of anything. They were created by simply pouring ink onto a sheet of paper and folding it in half. The only meaning and structure the cards have are provided by the projections of the test taker himself.

Human Differences: Culture, Gender, and Sexuality

"Everybody is unique!" is the mantra of the modern era. Many people pride themselves on being different and one of a kind — particularly in Western popular culture and media — and anybody spending any time studying and working with people will tell you there is a great deal of truth to this. Three of the most prominent, salient, and obvious variations among people are differences in culture, gender, and sexuality/sexual orientation.

Psychology and culture

You live in a truly global society. People are more connected than ever, the world seems smaller, and you can encounter an array of differences at a pace and scale never before seen in history. In the past, you might be lucky if you met someone from a different culture once a month (depending on where you lived). Now, you can meet people from all over the world on the bus, at Starbucks, or online. Psychology as a field would be incomplete without an understanding of how different cultural contexts influence individual minds and behavior. Cross-cultural psychologist John W. Berry at Queen's University in Canada proposes that much of what is known as "psychology" is what he calls "culture bound" and "culture-blind":
  • Culture-bound: Psychology is most popular in Western societies (Europe, the United States, and Canada). As such, it has limited understanding of people outside of those regions — not exactly a universal science considering that the majority of the world's population lives outside of those areas.

  • Culture-blind: The psychology of Europe, the U.S., and Canada has a tendency to largely ignore the influence of culture on the mind and behavior.

How do you address these issues? Cross-cultural psychology is the study of how culture influences the mind and behavior. And when referencing "culture," think on a societal level. This can be religious groups, ethnic groups, or even geographic groupings, such as "Californian" — and if you think there aren't different cultures in California compared to New York, just ask a New Yorker.

Choosing a view: From the inside or out?

Two approaches that a researcher can use to gain insight and information from another culture and its practices are the emic and etic techniques, first developed by K.L. Pike in the 1960s.
  • Emic: The emic method involves approaching a culture different from one's own without preconceived notions as an "outsider" and seeking to understand from the perspective of the "insider" of that culture. An example of an emic approach would be to investigate or collect data on intergroup conflict (for example, rival gangs in Los Angeles) from the perspective of the gang members themselves. This could be done by using a technique called the ethnographic interview, in which the research subject describes his or her experience as openly and freely as possible. An advantage to the emic approach is that it gives very authentic data, specific to a particular culture or group. A disadvantage is that the data or findings might not be applicable beyond that specific situation or group, posing a problem of generalization.

  • Etic: The etic method approaches understanding with all of the preconceived notions and methods of the "outsider." An example of an etic approach would be to investigate or collect data on gang-versus-gang conflict by administering a series of personality tests to individual members that were developed for the general population. An advantage to the etic approach is that findings might be more generalizable; a disadvantage might be that outside bias might influence the interpretation of the findings.

It is generally expected that a combined emic and etic approach is the best way to capture the complexities in cross-cultural research.

Exploring indigenous psychologies

Is there a "Japanese Psychology?" Is there a "Brazilian Psychology?" Is there a "Tamil Psychology?" The short answer is yes. One of the goals of cross-cultural psychology is to look for variations in "other" cultures that are not present in "our own." Not all mental disorders are found in all cultures; or, at the very least, the manifestation of specific disorders varies somewhat or to some degree. The hallucinations of schizophrenics, for example, vary by culture (seeing things versus hearing things, or smelling things). Indigenous psychology also studies culture-bound syndromes — mental disorders that are only recognized and manifest in specific cultures. Here are some of the more interesting ones:
  • Running amok (Malaysian origin): A sudden outburst of aggression or violence and running around wildly.

  • Falling out (African American; Caribbean): Alteration in consciousness including passing out in response to stress.

  • Susto (Mexico, Central America, South America): Displaced soul resulting from trauma.

  • Koro (Asia): A man's sudden grasping of his penis for fear that it will retract into the body. For a women, fear that her nipples may protract.

  • Pibloktog (Arctic and Inuit): Seizure, losing consciousness, amnesia, breaking furniture, eating feces, yelling obscenities.

And something can be a norm in one culture that would be considered a disorder in another. For example, grieving in some cultures includes extended periods of mourning, not going out into public, wearing black, not remarrying, and not attending family events. These are expected norms. In Western cultures, this behavior might be diagnosed as depression. Other studies have noted other cross-cultural differences. For example, immigrants to North American from Haiti and Eastern Europe are less trusting of others than Western European Americans and African Americans. Asian Americans show fewer outwards signs of depression than European Americans, who clearly smile less and display more negative emotion when depressed.

Looking for universals

Are there psychological universals? Cross-culture studies have been conducted in a wide range of areas, such as developmental psychology, cognitive psychology, and psychopathology. Cross-cultural similarities have been found for such phenomena as theory-of mind, counting ability in infants, and mate preferences (in almost all cultures studied, men value attractiveness and chastity more than women do, and women value status and financial prospects). Ultimately, as can be found with many issues in psychology, the "answer" to the human universal versus cultural variability question is that broadly speaking, the components of the mind and human behavior can be thought of as (by varying degrees) both universal and variable across cultures.

Psychology and gender

Perhaps the most simple and obvious human differences are sex and gender, male or female, masculine or feminine. Nearly all descriptions of other people when we talk about them, tell stories, describe them, or research them include an accounting of sex and gender.

Sex refers to an individual's biological status as either male or female, including anatomy. For the most part, you are born with your sex. Gender is not so cut and dry. Gender refers to the behavior and characteristics defining masculinity or femininity, which is understood to be psychologically, socially, and culturally constructed. Gender can be correlated with sex to some degree, but everyone knows people who are sexually male who are feminine in gender and vice versa.

Finding a place in the continuum

Gender manifests itself psychologically and behaviorally in what psychologists call gender roles. A gender role is a collection of social norms and expectations for a person who identifies or is identified as either masculine or feminine, man or woman. The presence of gender roles in societies gives rise to stereotypes and biases, prejudices, and judgments, of course. However, the world is still very "gendered," and people are still pretty much viewed through the lens of gender role and gender role categories. Psychologist Sandra Bem developed the Bem Sex-Role Inventory as a way to characterize an individual's gender in relation to a scale. Bem's inventory identifies the following as characteristics typically associated with being masculine, feminine, or neutral:
  • Masculine: Acts as a leader, aggressive, ambitious, analytical, assertive, athletic, competitive, defends own beliefs, dominant, and forceful

  • Feminine: Adaptable, affectionate, cheerful, does not use harsh language, gentle to needs of others, soft-spoken, tender, warm, compassionate, and loyal

  • Neutral: Adaptable, conscientious, friendly, helpful, jealous, moody, secretive, solemn, theatrical, and unpredictable

There is no value judgment associated with Bem's breakdown. Certainly both masculine and feminine traits are valuable in their own right, and certainly their utility and usefulness will vary by situation and context.

Looking at gender differences

Gender stereotypes abound. Girls can't do math. Men are uncaring. We know that stereotypes are often a shortcut for critical thought and all too often take us down the wrong road. But consistent differences between men and women have been found in research, such as higher rates of aggression and violence in men, higher rates of substance abuse in men, and higher rates of depression in women. Women's and men's leadership styles vary as well, with women adopting a more democratic and participatory approach and men adopting a more autocratic and directive approach. At one point in history, scientists claimed that women had inferior brains. However, modern neuroscience demonstrates no difference in general intelligence between men and women. Some studies suggest that men perform better at spatial and math abilities while women have stronger verbal abilities, but these findings are so small that they are irrelevant in the real world. So, why are there so few women in science and technology? If it's not biology, then is it culture, family influence, or sexism? The answer to this question has yet to be found.

Psychology and sexuality

Whom are you sexually attracted to? Sexual attraction is part of what defines a person's sexuality. A person's sexuality consists of his or her
  • Sexual biology (for example, genitals and arousal)

  • Psychosocial functioning (attractions, emotions, and beliefs)

  • Behavior (masturbation and intercourse)

  • Clinical aspects (erectile dysfunction and fetishes)

  • Cultural aspects (prohibitions of premarital sex or gender roles)

Laying the building blocks of sexuality

The development of sexuality is thought to begin in childhood, or at least the roots of adult sexuality are thought to come from childhood.

Infants, toddlers, and young kids

Of course, one's sex first becomes evident at birth (or younger if you get a fetal ultrasound), thus marking the early stages of sexuality. A person's sex carries with it biological predispositions (attraction tendencies) and cultural expectations (he's going to be a "ladies' man"). The sexuality development process is just beginning. An infant's closeness with parents (being hugged, cuddled, bathed, and dressed) is a precursor to sexuality and it's possible that disruptions or unhealthy experiences in these interactions can lead to difficulties with sexuality later in life. (These are not seen as "sexual" experiences for an infant but rather precursors to later developed sexuality, as they relate to physical closeness.) As infants grow into "kids," there is a growing awareness and curiosity about their bodies and genitals. It is not unusual to see children "play" with their genitals and engage in "show" games to others. They may even stimulate themselves by rubbing their genitals against toys or other objects. Simultaneously, there is an awareness of parental reactions and attitudes toward the body in general and genitals in particular. These experiences can range from shaming, to embarrassment, to laughter, to acceptance. Keep in mind that an overly negative tone should be avoided. At some point, children inevitably asking how babies are made, and how parents respond to this varies widely. Some give a biologically informed talk, whereas others engage in elaborate fairy tales. It is best not to avoid this discussion because a curious child is bound to find out one way or another; parents should want to be in control of their child's access to that type of information. Crushes and attractions start to emerge and children may even talk about "marrying" or "having a boyfriend" in reference to a class or playmate.

Approaching adolescence

As children approach adolescence they have a fairly clear understanding of the anatomical differences between boys and girls. Attitudes toward nudity in the home can change as children become more "mature." Kids may engage in "playing house" or "doctor" as a way to explore their sexual arousal, attractions, and bodies. Experimentation may be with either gender. This type of sex play is not generally considered harmful under ordinary and relatively innocent circumstances. However, behavior that appears to be "age-inappropriate" such as overly adult-like actions and adult sexual language use may be a warning sign of possible inappropriate sexual exposure or abuse. Also look for the following warnings that a child may be being sexually abused:
  • Refusal to change for gym or to participate in physical activities

  • Reluctance to be left alone with a particular person or people

  • Sexual knowledge, language, and/or behaviors that are unusual and inappropriate for their age

There could be other reasons for these behaviors, but take seriously any suspicion of sexual abuse of children.

Puberty and adulthood

Puberty marks a significant stage of sexual development. Bodies and physiology go through immense changes. Surveys suggest that the average age of first intercourse is 16 years old for boys and 17 years old for girls. Teen pregnancy and sexually transmitted diseases become real concerns as well. These issues remain ongoing into adulthood.

Defining healthy sexuality

Having a "healthy sex life" is common fodder for daytime talk shows, books and magazines. Defining healthy sexuality is not about moralizing or upholding any particular set of cultural values per se, but is seen as a "health issue" and is defined in terms of a healthy adult relationship in which the rights, well-being, and satisfaction of all involved is central.

Deciding what's attractive

Every year, people spend billions of dollars trying to make themselves more attractive. And people also want someone "good-looking" to be with. It's not just physical attributes, personality plays a big role in who you are attracted to, as do a host of other attributes such as moral values and career. Where do our attraction preferences come from? Once again, nature and nurture are at play in the development of sexual attraction. From a biological (nature) perspective, sexual attraction is referred to as sexual selection and is understood within an evolutionary context. Sexual attraction is a function of keeping the species alive! But attraction is immensely individualized and heavily culturally influenced. What might make one person attractive to one person and not another is subjective. Research has turned up some features common to both female and male attractiveness, however, such as financial stability, waist-to-hip ratio (curvaceousness) in women, and the "inverted triangle" (shoulders, chest, waist) for men. However, these must not be oversold. Not everyone likes blondes, or curves, or muscles, or . . . you get the idea.

Getting your bearings on sexual orientation

There is great variety in sexual attraction, but one determinant that plays the biggest role is sexual orientation, defined as an individual's patterns of emotional, romantic, and sexual attractions to men, women, or both sexes. Sexual orientation exists on a continuum with three main orientations: heterosexual (attractions to the opposite sex), gay/lesbian (attractions to the same sex as oneself), and bisexual (attractions to both men and women).

Sexual orientation is considered separate from one's biological sex and gender identity. You could be a "feminine" (gender) male (sex) who is attracted to women (heterosexual) or a "masculine" woman attracted to women.

The causes of sexual orientation have yet to be firmly discovered through scientific research. It is considered both biologically determined and environmentally shaped. Research shows the relative influence of such variables as genetics, hormones, and cultural influences, but no one factor has been crowned "the cause." Some people have judged that being gay, lesbian, or bisexual is a lifestyle "choice" that a person makes, but many gay men, lesbian women, and bisexual men and women report feeling as if they had "no choice" and simply knew how they felt from an early age. They simply were attracted to whom they were attracted to, period. Until 1973, being gay or lesbian was considered a mental disorder and was diagnosable by psychiatrists with the aim of providing "treatment." Mainstream psychology now considers these sexual orientations as normal variations of human sexuality. These are not disordered people — just people. It is important to note that prejudice and discrimination continue to negatively impact members of the LGBTQ (Lesbian, Gay, Bisexual, Transgendered) community, and these influences can lead to stress-related difficulties. Rather than viewing these sexual orientations as disorders, psychology has come to focus on helping individuals in the LGBTQ community overcome and cope with discrimination. Psychologists have developed programs focused on helping teens to "come out," especially those in communities that still have a difficult time accepting people who are gay, lesbian, bisexual, or transgendered. Psychologists also explore gay, lesbian, bisexual, and transgendered social and identity development. Therapies and therapists claiming to be able to change an individual's sexual orientation (for example, if a man no longer wishes to "be gay") have not been demonstrated to be effective from a scientific perspective. Such "treatments" are considered outside the mainstream, and are not supported by the American Psychological Association.

2 Psychological Tests to Measure Intelligence and Neuropsychological and Cognitive Ability

Any number of different disciplines are involved in mental illness treatment and working with people with mental disorders. Psychological testing, however, is considered the sole domain of psychologists. Although some professionals, including school counselors and learning disability specialists, conduct psychological testing, their testing is limited in scope and to a specific problem. Psychologists are thoroughly trained in all aspects of psychological testing and are the primary professionals in this area. Testing formats include surveys, pencil-and-paper tests, exercises and activities (like putting a puzzle together), interviews, and observation. Psychological testing focuses on the subject matter of psychology, behavior, and mental processes.

Intelligence tests

Intelligence tests may be the most frequently administered type of psychological test. They measure a broad range of intellectual and cognitive abilities and often provide a general measure of intelligence, which is sometimes called an IQ intelligence quotient. Intelligence tests are used in a wide variety of settings and applications. They can be used for diagnostic purposes to identify disabilities and cognitive disorders. They’re commonly used in academic and school settings. Intelligence tests have been around since the beginning of psychology as an established science, dating back to the work of Wilhelm Wundt — one of the founders of psychology — in the early 20th century. The most commonly used tests of intelligence are the Wechsler Adult Intelligence Scale, 4th Edition, for adults, and the Wechsler Intelligence Scale for Children, 4th Edition, for children. Each of these tests contains several subtests designed to measure specific aspects of intelligence, such as attention, general knowledge, visual organization, and comprehension. Both tests provide individual scores for each subtest and an overall score representing overall intelligence.

Neuropsychological and cognitive tests

Although not a new field, tests of neuropsychological functioning and cognitive ability, related specifically to brain functioning, are rapidly becoming a standard part of a psychologist’s testing toolset. Neuropsychological tests have traditionally been used to augment neurological exams and brain imaging techniques (such as MRIs, CT scans, and PET scans) but they’re being used more widely now in psychoeducational testing and other clinical testing situations.

The technology of scanning techniques picks up on the presence of brain damage, but neuropsychological tests serve as a more precise measure of the actual functional impairments an individual may suffer from. Scans say, “Yep, there’s damage!” Neuropsychological tests say, “. . . and here’s the cognitive problem related to it.”

Neuropsychological testing is used in hospitals, clinics, private practices, and other places where psychologists work with patients who are suspected of neuropsychological impairment. People suffering head trauma, developmental disorder, or other insults to the brain may need a thorough neuropsychological examination. A popular neuropsychological test is a collection of tests called a test battery. The Halstead-Reitan Neuropsychological Test Battery includes tests that measure neuropsychological constructs, such as memory, attention and concentration, language ability, motor skills, auditory skill, and planning. Completing the battery requires several hours, and it’s never done in one sitting. However, when conducted by a competent professional, the testing can yield a tremendous amount of helpful information. Many neuropsychological instruments are available; some are comprehensive, like the Halstead-Reitan, and some are designed to measure a specific function such as language or attention. A neuropsychological evaluation is conducted using a comprehensive instrument or a collection of individual instruments to create a profile of neuropsychological strengths and weaknesses. The following areas of neuropsychological functioning are typically assessed:
  • Executive Functions: Focusing, planning, organizing, monitoring, inhibiting, and self-regulating

  • Communication and Language: Perceiving, receiving, and expressing self with language and nonverbal communication

  • Memory: Auditory memory, visual memory, working memory, and long-term memory

  • Sensorimotor Functions: Sensory and motor functions, including hearing, touch, smell, and fine and gross muscle movements

  • Visual-Spatial Functions: Visual perception, visual motor coordination, visual scanning, and perceptual reasoning

  • Speed and Efficiency: How fast and how efficient thinking is
