Parental Influence, Justin Burgess, Lisa K. Lashley, Charles J. Golden Apr 2025

Parental Influence, Justin Burgess, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

An adequate level of parenting—providing enough nutrition, shelter, exposure to language and peers, or not harshly punishing children (punching, kicking, striking with a weapon)—seems to not have a long-term effect on cognitive development in children. Twin and adoption studies have found that intelligence is accounted for almost entirely by genes and nonshared environment, which includes peers, teachers, and unique experiences. However, there are parenting styles and types of home environments that are correlated with better school performance, stronger school engagement, and more words spoken at certain ages.

Gifted Children, Justin Burgess, Lisa K. Lashley, Charles J. Golden Apr 2025

Gifted Children, Justin Burgess, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Children can be gifted in a variety of different areas, including musical talent, athleticism, and artistic ability among others. The focus of this entry will be solely on those children who are gifted in intellectual ability and academic achievement. Identification of intellectual giftedness usually requires an individually administered intelligence test, achieving a Full-Scale Intelligence Quotient (FSIQ) of 130 or higher, which is a threshold that dates back to Lewis Terman’s research at Stanford in the early to mid 20th century. Although this seems like an arbitrary score, an IQ score of 130 and above is where an individual scores two …

The Marshmallow Task, Laurel A. Brabson, Hannah M. Coffey, Mary Margaret Ruckle, Cheryl B. Mcneil

Essays in Developmental Psychology

To study the human systems of self-control during delayed gratification, Dr. Walter Mischel and colleagues developed what became the famous Marshmallow Test, published in Science in 1989. This study became a frontrunner in the field of psychology, laying the foundation for future studies in impulse control. Dr. Mischel was born in 1930 in Vienna, Austria. He was a professor at the University of Colorado, Harvard University, and Stanford University where he originally conducted the Marshmallow Test. Dr. Mischel currently holds a professorship at Columbia University.

Craik & Lockhart: Levels Of Processing, Macey Cartwright, Heidi Kloos Apr 2025

Craik & Lockhart: Levels Of Processing, Macey Cartwright, Heidi Kloos

Essays in Developmental Psychology

What is the nature of mental activity that allows a child to remember a past experience? Traditionally, the question of memory was answered with an exclusively static model: The mind was said to have storage bins to which represented experiences are added. Depending on the exact nature of the storage bin, the experience is remembered either for a short time (i.e., shortterm memory) or for a long time (i.e., long-term memory). Though widely familiar, this model of static storage bins falls notoriously short on explaining the nuance of memory findings. For example, short-term memory appears to have strict capacity limits …

Representative Sampling, Jessica Choe, Lisa K. Lashley, Charles J. Golden Apr 2025

Representative Sampling, Jessica Choe, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

The research process begins with an initial observation that scientists or researchers of various backgrounds want to engage in and understand, which prompts them to formulate theories and hypotheses, collect data, and use statistical procedures to organize, summarize, and interpret gathered data. Research conducted through questionnaires or surveys are often utilized to determine the nature of a population or the interests of members in a particular group.

Possible Selves, Chris Burley, Lisa K. Lashley, Charles J. Golden Apr 2025

Possible Selves, Chris Burley, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Self-concept is an individual’s idea of who the individual was in the past, who the individual is at present, and who that individual has the potential to become in the future. When considering self-concept, group memberships and other social roles typically shape how an individual thinks about him- or herself. A strong self-concept helps an individual to make sense of his or her present situation, maintains positive feelings through difficult situations, make sensible predictions about the future, as well as helps to sustain motivation.

Intersensory Redundancy, Macey Cartwright, Heidi Kloos Apr 2025

Intersensory Redundancy, Macey Cartwright, Heidi Kloos

Essays in Developmental Psychology

How does redundancy in the input affect the child’s attention? Consider, for example, a scenario in which the child is listening to a parent’s utterances, as well as watching the parent’s lips moving in synchrony with the speech. Intuitively, one might assume that there is an inherent advantage in such informational coherence. The match between sounds and visual input might help constrain attention in productive ways. Alternatively, a mismatch in intersensory information might affects attention negatively. The reality of how intersensory redundancy affects a child’s attention is more surprising than what intuition might suggest, as we discuss in this essay.

Psychomotor Speed In Old Age, Cheryl Chakranarayan, Nathan C. Weed Apr 2025

Psychomotor Speed In Old Age, Cheryl Chakranarayan, Nathan C. Weed

Essays in Developmental Psychology

Psychomotor ability is defined in terms of the relationship between cognitive functions and motor activities. It plays an important role in acquiring and carrying out a broad range of physical skills and coordinated behaviors, such as playing a sport, or in everyday activities like pouring a glass of milk or applying makeup. Psychomotor speed therefore is the rate at which a certain psychomotor behavior can be carried out. Because of the relevance of psychomotor speed to many areas of personal functioning, it has been extensively studied in a wide variety of applied contexts including sports performance, personnel selection within the …

Social Exchange Theory, William Goulart, Lisa K. Lashley, Charles J. Golden Apr 2025

Social Exchange Theory, William Goulart, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Exchange theory originated in the field of sociology in the 1920s. However, since the late 1950s and early 1960s, social exchange theory has been a major school of thought in the field of both social psychology and sociology. This is largely due to the work of George Homans, John Thibaut, Harold Kelley, and Peter Blau. Social exchange theory describes all human interactions as a series of trades or exchanges of rewards between actors.

Unemployment, David A. Scott, Caroline Sumner, Taylor Roberson, Rachel Edwards Apr 2025

Unemployment, David A. Scott, Caroline Sumner, Taylor Roberson, Rachel Edwards

Essays in Developmental Psychology

Unemployment is a difficulty that millions of Americans face on a yearly basis. Unemployment is a multifaceted concern that impacts the individual, including their financial security, their family, and the larger community systems. The Bureau of Labor Statistics (BLS) reported the unemployment rate at 4.1% in 2017, which is the lowest unemployment rate since 2000. Based on the BLS’s 2016 statistics, African Americans suffer with the highest unemployment rates, followed by Hispanics, Whites, and lastly, Asians. However, statistics only tell part of the story. According to the BLS, unemployment is classified as “people who are jobless, are actively seeking work …

Success And Intelligence, Halie B. Hamilton, Nathan C. Weed Apr 2025

Success And Intelligence, Halie B. Hamilton, Nathan C. Weed

Essays in Developmental Psychology

One of the most famous studies tracking the relationship between intelligence and success was conducted by Louis Terman. Terman’s Gifted Child Study began in the 1920s and followed nearly 1500 gifted children throughout their lives. To qualify, the children had to have an IQ of at least 140. The children were followed into adulthood to see how their intelligence was related to social and personal adjustment. Terman found that his sample showed not only positive academic outcomes, but also tended to be healthier, taller, and stronger than children with lower IQs. These positive effects persisted into adulthood. Two-thirds earned bachelor’s …

Vision In Infants, Brianna Mcgee, Rachel Wu Apr 2025

Vision In Infants, Brianna Mcgee, Rachel Wu

Essays in Developmental Psychology

There is a great deal of visual development over the first year of life. Many aspects of vision undergo this dramatic change, including visual perception (the ability to see and interpret information), visual acuity (the clarity of our vision), and smooth pursuit (the ability to follow objects). These three aspects are fundamental to early visual experiences that facilitate typical cognitive development. This entry will provide a brief overview of visual perception, visual acuity, and smooth pursuit in human infants.

Student Motivation - Traditional Vs. Nontraditional College Students, Marcus Lee Johnson Apr 2025

Student Motivation - Traditional Vs. Nontraditional College Students, Marcus Lee Johnson

Essays in Developmental Psychology

Traditional-aged college undergraduate students are typically between the ages of 18 and 23 years and pursue their college education immediately after graduating from high school. Nontraditional undergraduate students tend to be older than 24 years in age or have taken time off from pursuing higher education. Many nontraditional students have reported having parental responsibilities, mortgages, or career responsibilities. Despite these perceived challenges, the nontraditional student population has tripled in size since the 1970’s and is projected to continue growing steadily in the coming years.

Stress (Personality Types), Alison Datoc, Lisa K. Lashley, Charles J. Golden Apr 2025

Stress (Personality Types), Alison Datoc, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Both stress and personality types are multifaceted topics that have been defined in multiple ways.  Examining the relationship between stress and personality types is complex; however, literature on this relationship is well-established. While early research on the relationship between personality and stress focused on unidimensional personality traits, such as the relationship between stress and Type A personality, optimism, and hostility, research in this field today takes a comprehensive approach conceptualizing personality in five dimensions. The most widely accepted method of defining personality today is the Big Five model, consisting of five independent factors of personality: Extraversion, Neuroticism, Agreeableness, Openness to …

Stereotype Thinking, Lisa Stebbins, Lisa K. Lashley, Charles J. Golden Apr 2025

Stereotype Thinking, Lisa Stebbins, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Stereotypes are widely held fixed thoughts and beliefs adopted by common members of a group, that represent a particular group of individuals or behaviors as a whole. Attitudes people hold reflect in-group beliefs, values, and everyday life choices that are transgressed throughout multiple generations.  Stereotypes are intertwined into society, and although many people would like to deny these attitudes, they are implanted on individuals when we are young and occur without conscious awareness. Stereotype thinking is adaptive in nature, which serves the purpose to help people make sense of the world around them, by explaining social events, justifying one’s actions, …

Career Plateauing, Victor Tran, Lisa K. Lashley, Charles J. Golden Apr 2025

Career Plateauing, Victor Tran, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

A career plateau can be defined as a phenomenon in which an individual’s career becomes stagnant. It is imperative to distinguish the two types of career plateaus: (1) content (job content) plateauing and (2) structural (hierarchical) plateauing. Content plateauing refers to a situation in which an individual’s job content (i.e., knowledge, skills, duties, responsibilities, etc.) stops changing. While structural plateauing assumes content plateauing, it also refers to a situation in which an individual can no longer progress, advance, or be promoted within the hierarchical framework of an organization. Career plateauing is not a novel phenomenon; however, it has progressively become …

Urie Bronfenbrenner, Wallace Fullerton, Donna Devaughn Kreskey Apr 2025

Urie Bronfenbrenner, Wallace Fullerton, Donna Devaughn Kreskey

Essays in Developmental Psychology

Urie Bronfenbrenner (born April 29, 1917, Moscow, Russia – died September 25, 2005, Ithaca, New York, U.S.) was a Russian-born American developmental psychologist. He is best known for ecological systems theory. This theory explains human development as the result of nested relationships between the individual and family, friends, schools, neighborhoods, society, and the time period in which the individual lived. Bronfenbrenner described these contexts as, matryoshka, or Russian nesting dolls. The individual was layered within multiple contexts, or systems and each system was represented by one of the nested dolls. The ecological system of each individual was built from five …

Types Of Play, Rebecca Mcmahon Giles Apr 2025

Types Of Play, Rebecca Mcmahon Giles

Essays in Developmental Psychology

Rather than using a universally agreed upon definition of play, the following list of characteristics, first presented in the widely cited Association of Childhood Education International position statement on play, "Play: A Necessity for All Children" (ACEI/Isenberg & Quisenberry, 1988), is used to distinguish play from non-play behaviors:  intrinsically motivated and self-initiated; process oriented; non-literal and pleasurable; exploratory and active; and rule-governed. Types of play have been categorized according to both the degree of social participation (Parten, 1932) and the level of cognitive functioning (Piaget, 1962; Vygotsky, 1967).

Trait Stability, Gregory John Vitale Apr 2025

Trait Stability, Gregory John Vitale

Essays in Developmental Psychology

Trait stability is the concept that personality structures largely remain consistent over time. Traits, like many concepts in psychology, tend to be considered one part nature and one part nurture; that is, individuals are born with some qualities and learn to employ others based on their environment. Psychologists have taken the concept of innate traits and made inferences about how they may or may not be related to some psychological disorders, especially personality disorders, and have found mixed results. This has immense developmental implications. For one, despite a child’s temperament traits at an early age, the environment can change them. …

Adolescent Social Development, Randall E. Osborne Apr 2025

Adolescent Social Development, Randall E. Osborne

Essays in Developmental Psychology

Views about the manner and nature of human development have changed across time (Psyking.net 2016). Some of these views have been religious (e.g., creationism) and some of these views have been more biological (e.g., preformationism).  Regardless of the focus of the view, how we believe human beings develop has a profound effect on our expectations for those beings.  One early view of human development from a biological perspective was Preformationism.  This is explained as, “A notion that was widespread among pioneer biologists in the 18th century was that the fetus, and hence the adult organism that develops from it, is …

Sibling Relationships In Old Age, Ronald Okolichany, Lisa K. Lashley, Charles J. Golden Apr 2025

Sibling Relationships In Old Age, Ronald Okolichany, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

The relationship between siblings is unique among family relationships in that sibling relationships have a dimension of equality. In other words, they do not necessarily share the same obligations toward each other as a married partners or parents and child may, especially in Western cultures. Durkheim (1933) described sibling relationships as a “mechanical” bond rather than an “organic” bond, which would better characterize a complimentary relationship, such as that between married partners or a parent and child. This mechanical bond results in ambivalence and rivalry towards one another during childhood and early adulthood, as siblings are often forced to compete …

Cognitive Dissonance, Afton Nelson, Eric A. Goedereis Apr 2025

Cognitive Dissonance, Afton Nelson, Eric A. Goedereis

Essays in Developmental Psychology

Leon Festinger proposed the theory of cognitive dissonance in 1957, in which he extensively outlined the major derivations of dissonance, consonance, and justification (Festinger & Carlsmith, 1959). In short, cognitive dissonance occurs when one’s actions are inconsistent with previous beliefs about one’s self. The inconsistency in these beliefs creates conflict within the self. For example, an individual may think of herself as a good person, yet she breaks a law. In this example, there is inconsistency between one’s current action and prior beliefs about the self.

John B. Watson, Afton Nelson, Amanda Kracen

Essays in Developmental Psychology

John B. Watson (1878 – 1958) was an influential American psychologist credited with advancing behaviorism, a psychological approach that considers all behavior to be a result of interactions with the external environment.

Ethical Research, Stephanie Nguyen, Aya Shigeto

Essays in Developmental Psychology

In the early history of empirical research, the ethical code of conduct was only loosely followed and not well regulated. Now, following a proper code of ethics is expected in research with committees from the institutional to the international level strictly regulating and holding researchers accountable for their work. Research ethics address questions, such as whether a study will produce the greatest good; who is intended to benefit from a study at the expense of others; and how research participants, especially those from vulnerable populations (e.g., pregnant women; minors; people in impoverished circumstances, with disabilities, or from minority groups), should …

Piaget's Conservation Experiments, Motolani Shenbanjo, Heidi Kloos Apr 2025

Piaget's Conservation Experiments, Motolani Shenbanjo, Heidi Kloos

Essays in Developmental Psychology

When it comes to assessing the magnitude of a quantity, the mind has several options. For example, to determine the amount of juice in a glass, one could merely look at the height of the juice in the glass; or one could incorporate both the height and the width of the glass. The latter would be the correct approach: The height alone can be misleading, for example when the glass is very narrow. Thus, in order to behave rationally, one has to look past the salient dimension of height and instead focus on integrating several dimensions. According to Jean Piaget, …

Job Satisfaction (Motivation / Work / Employee / Satisfaction), Veronica Stelzer, Jonathan Proctor Apr 2025

Job Satisfaction (Motivation / Work / Employee / Satisfaction), Veronica Stelzer, Jonathan Proctor

Essays in Developmental Psychology

Satisfaction is a multifaceted emotional state of being that is derived from the fulfillment of expectations, wants, and needs. Reaching a level of satisfactory creates contentment, pleasure and even pride, but in order to achieve this state of well-being the task must be reasonably challenging, purposeful and appreciated. Today, job satisfaction is a topic that interests many. Satisfaction surveys are completed yearly, if not quarterly, to assure employees are feeling heard and understood. Some businesses such as Facebook and American Express have employee satisfaction ratings that top the charts, other places of work, suffer from high turnover rates and lack …

Infant Speech Perception And Babbling, Brian Schanding Apr 2025

Infant Speech Perception And Babbling, Brian Schanding

Essays in Developmental Psychology

Much work in the study of early life speech perception centers on an infant’s ability to discriminate sounds. Studies rely on an infant’s reactions to spoken language, measured by various physical and biometric responses, as evidence of an infant’s ability to perceive distinct spoken sounds. Studies have identified a number of characteristics of human speech, termed cues, which infants have demonstrated they can recognize.
