Research Design Types

Cross-Sectional Design

• A cross-sectional design is used for research that collects data on relevant variables one time only from a variety of people, subjects, or phenomena.
• A cross-sectional design provides a snapshot of the variables included in the study at one particular point in time.
• Cross-sectional designs generally use survey techniques to gather data, for example, the U.S. Census.

Advantages

• Data on many variables
• Data from a large number of subjects
• Data from dispersed subjects
• Data on attitudes and behaviors
• Good for exploratory research
• Generates hypotheses for future research
• Data useful to many different researchers

Disadvantages

• Increased chances of error
• Increased cost with more subjects and each location
• Cannot measure

Metaphors for Culture in a Global Village

Global access to the world village means we don't have to leave home. This interaction is often described with metaphors:

• Melting Pot: Cultures blend together into one.
• Fruit Salad: Cultures are mixed but remain separate and distinct.
• Pizza Supreme: Cultures are held together by a cohesive bond (the cheese).

The Role of Language and Non-Verbal Communication

Kinesics, Proxemics, and Chronemics

Kinesics, the study of body language and gestures, plays an important role in communication. Other key areas include Proxemics, which involves preferences for space, and Chronemics, which involves preferences for time.

The Nature of Language

Language is symbolic. A symbol is an arbitrarily selected, learned “sign” that... Continue reading "Core Concepts in Culture, Language, and Communication" »

The Case of Henry Molaison (Patient H.M.)

Henry Molaison, most known as patient H.M. (1921–2008), suffered from severe seizures. In an attempt to cure his epilepsy, he underwent a bilateral medial temporal lobectomy, during which his hippocampus was removed. At the age of 27, following this major surgery, his seizures ended, but his ability to form new explicit memories was lost. While his epilepsy was controlled, he suffered from heavy anterograde amnesia. His working memory and implicit memory remained intact, but he could not add new events to his explicit memory. His old memories remained untouched, but from that day forward, he was forced to "live in the present."

His case is arguably the most influential in the study of memory and has... Continue reading "Psychology Fundamentals: Memory, Gender, and Perception" »

The Cognitive Approach to Sleep

Definition/Explanation:

The cognitive approach views sleep as something that facilitates information processing. Sleep is used to secure information gathered during the day in long-term memory. Memories and learning are moved to long-term storage during sleep.

According to the cognitive approach, dreams are not meaningless. In fact, they are essential points of our problem-solving process and allow information to be synthesized and recombined to gain insight.

Domhoff (2011) argued that dreams are what occur when the mind doesn't have anything else to do. During the day, we daydream, but during the night, we aren't in control, and our dreams seem more vivid and engrossing. He believes that dreams are mental processes...

What is Psycholinguistics?

Psycholinguistics is the study of the psychological aspects of language, the relationships between psychology and language, our neural capacity, and speech perception and production.

It is the study of language from the point of view of psychology, trying to understand how language is produced and understood.

Branches of Psycholinguistics

• General psycholinguistics: Theories of language functioning in adult language users.
• Developmental psycholinguistics: Mainly focuses on language acquisition by children.
• Applied psycholinguistics: Covers reading, writing, and bilingualism.

Related Disciplines

Psycholinguistics has several "siblings": neurolinguistics, biolinguistics (the origin and biological foundations of language), and... Continue reading "Psycholinguistics: Language Production and Perception" »

2. One of the most consistently damaging teratogens is alcohol.
3. The symptoms of fetal alcohol syndrome are most likely to include mental abnormalities.
4. The rooting reflex refers to a baby's tendency to open the mouth in search of a nipple when touched on the cheek.

Early Cognitive Abilities

5. In order to test whether newborns can visually discriminate between various shapes and colors, psychologists have made use of the process of habituation.
6. The best evidence that a 4-month-old infant possesses an understanding of object permanence is the child's
