Midlife Stress, Kimberly Diah, Lisa K. Lashley, Charles J. Golden Apr 2025

Midlife Stress, Kimberly Diah, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Midlife stress occurs naturally through the aging process but can be the result of an external psychological stressor due to loss or change such as occupational stress, health concerns, parental bereavement and divorce. Coping with the psychological suffering associated with these stressors brings challenges throughout all stages of life, but when it occurs during midlife it can be complicated by heightened or unique feelings of bewilderment. For men, recognition of their own mortality and sense of purpose in life can drive the experience of midlife stress. For women, this experience may be derived from feelings of emptiness and sadness, physical …


Information Processing Theory (R.J. Lachman), Kimberly Diah, Lisa K. Lashley, Charles J. Golden Apr 2025

Information Processing Theory (R.J. Lachman), Kimberly Diah, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Information Processing Theory is a cognitive approach designed to understand human learning. Several perspectives of this theory emerged from the cognitive revolution in psychology beginning in the 1950s. The invention of the technological age of computers brought with it an innovative way of understanding how information is processed in humans. This lead researcher to draw analogies between the processing ability of humans and computers. The human-computer analogy developed from the foundation that as computers are able to process information so too can humans in a very similar method. Both encompasses ‘cognitive’ processes such as learning or obtaining information, solving problems, …


Mathematical Skills, Rhonda Douglas Brown Apr 2025

Mathematical Skills, Rhonda Douglas Brown

Essays in Developmental Psychology

Mathematical Skills are essential for understanding how the world works and for solving problems that are important to human survival and prosperity.  They are used in everyday living in societies across the world.  The most basic mathematical skills involve estimating the amount of small sets of items without using symbols, called number sense, and tracking a small number of individual objects through space and time, called parallel individuation.  These skills are thought to be present at birth or early in life and to increase in precision into adulthood.

Lifespan Perspective, Leila Eikevik Apr 2025

Lifespan Perspective, Leila Eikevik

Essays in Developmental Psychology

Psychologists who study human development have adopted the lifespan perspective, which maintains that important changes occur during every period of development and that these changes must be interpreted in terms of the culture and context in which they occur (Boyd and Bee, 2009). Prior to this understanding, the subject of development was limited to childhood. This view has shifted because it is evident adults continue to experience major life changes and there has been a significant increase in age expectancy. Therefore, all stages of life are equally important. Lifespan development begins at the time of conception and continues up until …


Marriage, Kim Fitzgibbon Apr 2025

Marriage, Kim Fitzgibbon

Essays in Developmental Psychology

Official legislation on the touted “fundamental right” of marriage dates back to the 1800s in the United States, showing the prominence and important that the concept of marriage has on society. Changes in laws and policy have increased the opportunity for marriage to a larger population and as such, research on the construct, its benefits, challenges and statistics has become an area of significant interest. The legal and financial implications of a marriage contract have also encouraged researchers due to the serious and long-lasting implications such a contract can have. Reasons to marry are endless, are highly individualized and can …


Naïve Theories, Ethan Fleuchaus, Heidi Kloos Apr 2025

Naïve Theories, Ethan Fleuchaus, Heidi Kloos

Essays in Developmental Psychology

While the idea of the mind as a blank slate has long been abandoned, the question of what exactly a “non-blank slate” might look like is still debated. In this entry we discuss the claim that children are equipped with naïve theories—primitive, incomplete, or otherwise ill-formed, but nevertheless systematic, mental representations of cause-effect relations. Other terms that reflect this idea include ‘misconceptions’, ‘naïve beliefs’, ‘prior theories’, ‘alternative conceptions’, or ‘intuitive theories’. Their main characteristic is that they interfere with an open-minded exploration of the surrounding. The unfortunate result of such biased exploration is that children ignore evidence that conflicts with …

Heinz Werner, Ethan Fleuchaus, Katie Cunningham, Heidi Kloos

Essays in Developmental Psychology

Heinz Werner (February 11, 1890 – May 14, 1964) was an Austrian psychologist who played an active role in defining the field of developmental psychology at the start of the 20th century. While initially seeking to become a composer and music historian, he changed his mind after listening to a lecture on Immanuel Kant at the University of Vienna. Werner became engrossed in topics of philosophy and psychology (which were combined at the time), and he wrote his dissertation on the psychology of aesthetic experiences. Subsequently he worked at the University of Hamburg, where he published the first edition of …


Patriarchal Violence, Fallon Flowers, Lisa K. Lashley, Charles J. Golden Apr 2025

Patriarchal Violence, Fallon Flowers, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Patriarchal violence has been described as a pattern of behavior by men perpetuated against women in order to maintain control over women and their behavior. Ultimately, it is meant to oppress them; resulting in women being relegated to a lower position in society. The need for men to exert control over women via Patriarchal violence has roots in one’s cultural, societal, and moral beliefs. Such beliefs pertain to what is considered appropriate and what is considered inappropriate in a cultural context.  One of the burgeoning examples of this form of violence against women is the “honor killing”, the killing of …

Adolescent Death, Kim Fitzgibbon, Lisa K. Lashley, Charles J. Golden Apr 2025

Adolescent Death, Kim Fitzgibbon, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

According to recent statistics from the Center for Disease Control and Prevention (CDC), there are approximately 9,500 adolescent deaths per year in the United States, as defined by mortality rates for individuals aged 15-19. CDC statistics also show that the leading causes of death for American adolescents were unintentional accidents and injuries, suicide and homicide. Furthermore, according to David Balk’s Handbook of Adolescent Death and Bereavement, gender and racial differences contribute to disproportionate mortality rates, with African American and Hispanic males finding themselves significantly more likely to be killed by homicide than Caucasian counterparts.


Secondary Mental Abilities, Kim Fitzgibbon, Lisa K. Lashley, Charles J. Golden Apr 2025

Secondary Mental Abilities, Kim Fitzgibbon, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Mental abilities have commonly been broken down into two main categories; primary and secondary. Primary mental abilities are thought to be large scale groups with similar abilities. Secondary mental ability builds off foundational primary mental abilities of intelligence. Research has suggested that there are six main secondary mental abilities, with the potential for additional abilities to be named or discovered as more research emerges. Expanding research on these abilities has also suggested that they can morph and evolve with age, just as primary abilities related to intelligence.


Brain Study Techniques, Rhonda Douglas Brown Apr 2025

Brain Study Techniques, Rhonda Douglas Brown

Essays in Developmental Psychology

Brain study techniques are used to understand how the brain processes information and manages behavior.  They can establish which parts of the brain are responsible for different types of cognition and behavior.  One technique, called lesion studies, involves conducting case studies of patients with brain injury and associating damage in specific regions or structures with loss or impairment of specific cognitive processes and behaviors.  For example, in the mid1800s, using post-mortem autopsy, Paul Broca observed that patients who had lost the ability to speak, but could understand language, had damage in the posterior sections of the inferior frontal gyrus; whereas, …


Marriage In Old Age, Nicole M. Fornalski, Lisa K. Lashley, Charles J. Golden Apr 2025

Marriage In Old Age, Nicole M. Fornalski, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

As closely interactive cohorts throughout their adult lives, husbands and wives have been seen to become even closer confidants and partners in older age.  These changes may predominate after retirement and the loss of daily work practices and professional systems.  Older couples have frequently shared a considerable quantity of time with one another, and subsequently are able to call forth collective memories and years of intercommunications.  In addition, older adult couples usually report less conflicts, and appear to acquire more meaning out of their spousal relationships.  They also report less psychological distress and rates of illness than older singles.  These …


Role Transitions, Nicole M. Fornalski, Lisa K. Lashley, Charles J. Golden Apr 2025

Role Transitions, Nicole M. Fornalski, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

A role can be defined as one’s position in a relationship or social structure, whereas a role identity consists of the behavioral expectations that are included in that role. While some individuals may view their roles through a fixed set of social standards, others rely on their own subjective perceptions and interpretations of these positions through flexible guidelines.  Through the process of a role transition, the literature identifies two types defined as a macro role transition or micro role transition.  A macro role transition consists of a psychological or physical change between consecutively held roles.  Examples can include career transitions, …


Sexually Transmitted Diseases, Fallon Flowers, Lisa K. Lashley, Charles J. Golden Apr 2025

Sexually Transmitted Diseases, Fallon Flowers, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Sexually Transmitted Diseases (STDs) are diseases that can be passed from one person to another via sexual contact. Some STDs can be treated and cured, while others, once contracted, remain for a lifetime. Chlamydia is one of the more common STDs that both women and men are susceptible to. It is the result of exposure to a bacteria called Chlamydia Trachomatis. In women, the infection can occur in the cervix, throat, or rectum, while men who are infected experience the infection inside the penis (urethra), throat, and rectum. With regard to transmission, Chlamydia can be transmitted from one person to …


Grandparenthood, Ronald Okolichany, Lisa K. Lashley, Charles J. Golden Apr 2025

Grandparenthood, Ronald Okolichany, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

The transition from parenthood into grandparenthood is a normative experience for a majority of individuals and typically occurs in middle age. However, this transition is not uncommon for individuals over 65 or under 55. An individual’s first experience with grandparenthood generally occurs in childhood, when they interact with their grandparents as grandchildren. Initially, the bond between grandparents and grandchildren is mediated by the parents. However, over time the relationship between the two becomes more direct.


Preoperational Period, Huda Abu-Suwa, Lisa K. Lashley, Charles J. Golden Apr 2025

Preoperational Period, Huda Abu-Suwa, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

The preoperational period is part of Jean Piaget’s four stages of cognitive development (Lally & Valentine-French, 2019). Piaget was a cognitive psychology, who in 1936 created a model to explain how children understand the world and develop cognitively. While other contemporary theorists believed that intelligence was a fixed trait, Piaget believed that cognitive development was a process that occurred in distinct stages, and that maturation brings about changes and growth in development, rather than training (Lally & Valentine-French, 2019). Piaget posited that each stage occurred at a specific time and in a specific sequential order, such every child goes through …


Embryonic Stem Cell Research, Huda Abu-Suwa, Lisa K. Lashley, Charles J. Golden Apr 2025

Embryonic Stem Cell Research, Huda Abu-Suwa, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Stem cell research is a controversial issue that has received considerable attention over the last three decades. Stem cell research began in the early 1980’s, when stem cells were obtained from mice embryos and utilized to understand the functioning of stem cells (Grivennikov, 2008). In 1998, researchers discovered techniques for obtaining embryonic stem cells from human and growing them in laboratories. Since them, substantial research has been conducted on stem cells and their potential uses, which includes increasing our understanding of diseases and how they occur, treating various diseases, and testing new medications for safety and efficacy (Taylor, 2005).

Psychological Development: Cognition, Emotions, Personality, Anita Knight Kuhnley, Kelly Carapezza, Gary Sibcy Apr 2025

Psychological Development: Cognition, Emotions, Personality, Anita Knight Kuhnley, Kelly Carapezza, Gary Sibcy

Essays in Developmental Psychology

Adolescence is considered the age that bridges childhood and adulthood, Erik Erikson, who has contributed much to our understanding of the developmental stages described adolescence as, “the age mediating between childhood and adulthood (Erikson, 1997, p.xi).” Adolescence includes the sometimes tumultuous years between the ages of 11 and 21, and the Eriksons addressed this as one stage (Newman and Newman, 2013). Some authors attribute the fact that adolescence is such a trying time to the fact that adolescents lose synapses in the brain specifically in the primary visual cortex at a rate of 5,000 per second (Bears, Connor, and Paradiso, …


Fast Mapping, Heidi Kloos, Hannah Mcintire Apr 2025

Fast Mapping, Heidi Kloos, Hannah Mcintire

Essays in Developmental Psychology

In a classic study by Carey and Bartlett (1978), preschool children were presented with two trays and prompted to: “Bring me the chromium tray, not the blue one. The chromium one.” One week later, a new task context was used to test what children thought ‘chromium’ refers to (e.g., “Show me the chromium one”). Results show that 3- and 4-year-olds were able to learn the meaning of ‘chromium’ even after a single exposure. This phenomenon was termed ‘fast mapping’. It captures the mental process of narrowing down the meaning of a word during a casual experience. In the current essay, …


Personal Control Beliefs, Sarah Kurzu, Eric A. Goedereis Apr 2025

Personal Control Beliefs, Sarah Kurzu, Eric A. Goedereis

Essays in Developmental Psychology

Personal control refers to the degree to which an individual believes one is in control of his or her own life, as opposed to one’s circumstances being the result of factors outside of one’s control. An individual with high personal control has a stronger belief that he or she is able to produce desired outcomes within a designated domain. The beliefs themselves are broken down into two main constructs: external and internal control. Internal control emphasizes the responsibility of the individual and his or her actions on the outcome, while external control determines the outcome as being guided by an …

Adolescent Depression, Skip Kumm

Essays in Developmental Psychology

It is common for teens to experience depression. Researchers have found that up to one in eight youth experience some form of depression during their teenage years. It is also well known that all adolescents face many unique challenges related to school, finding a college, peer pressure, and hormones, which may result periods of sadness, frustration, and despair; however, depression is more than just feeling sad or not being happy, depression is a serious mental condition different from typical adolescent experiences.


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

Generativity, Chris Burley, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

In psychology, the term generativity refers to concern for the future and the need to offer positive contributions to future generations. The term first appeared in stage seven of Erik Erikson’s model of psychosocial development (generativity vs. stagnation). Erikson’s model postulates that generativity occurs explicitly in middle adulthood, but a more recent model of generativity created by Dan McAdams proposes that generativity occurs as a function of increasing cultural demand and concern for future generations, rather than a function of personality change (McAdams, 2001).


Complex Emotions, Jessica Choe, Lisa K. Lashley, Charles J. Golden Apr 2025

Complex Emotions, Jessica Choe, Lisa K. Lashley, Charles J. Golden

Essays in Developmental Psychology

Complex emotions are ways in which an individual reacts and respond to complex social situations when encountering people and situations in the social world. Thus, complex emotions are ways of coping and adapting to complex social situations. Complex emotions are mental representations that have been studied on a three-level analysis surrounding the body, mind, and society, which translates to the biological and the evolutionary, the mental and the psychological, and the social and the cultural. This approach has been referred to as the neurocognitive sociology of emotions.

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.
