By Todd Kashdan, George Mason University. Social anxiety occurs when we are overly concerned about being humiliated, embarrassed, evaluated, or rejected by others in social situations. Everyone experiences social anxiety some of the time, but for a minority of people, the frequency and intensity of social anxiety is intense enough to interfere with meaningful activities (e.g., relationships, academics, career aspirations). When a person’s level of social anxiety is excessive, social interactions are either dreaded or avoided, social cues and emotions are difficult to understand, and positive thoughts and emotions are rare, then that person may be diagnosed with social anxiety disorder (or social phobia). There are effective treatments—with both medications and psychotherapy–for this problem. Unfortunately, only a small proportion of people with social anxiety disorder actually seek treatment.

In the same way, all people naturally engage in mental comparisons with the people around them during the course of daily life. These evaluations can impact our motivation and feelings. In this module, you will learn about the process of social comparison: its definition, consequences, and the factors that affect it.

By Tiffany A. Ito and Jennifer T. Kubota, University of Colorado Boulder, University of Delaware.This module provides an overview of the new field of social neuroscience, which combines the use of neuroscience methods and theories to understand how other people influence our thoughts, feelings, and behavior. The module reviews research measuring neural and hormonal responses to understand how we make judgments about other people and react to stress. Through these examples, it illustrates how social neuroscience addresses three different questions: (1) how our understanding of social behavior can be expanded when we consider neural and physiological responses, (2) what the actual biological systems are that implement social behavior (e.g., what specific brain areas are associated with specific social tasks), and (3) how biological systems are impacted by social processes.

By Ross Thompson, University of California, Davis.Childhood social and personality development emerges through the interaction of social influences, biological maturation, and the child’s representations of the social world and the self. This interaction is illustrated in a discussion of the influence of significant relationships, the development of social understanding, the growth of personality, and the development of social and emotional competence in childhood.

By Robert Biswas-Diener and Jake Teeny, Portland State University, The Ohio State University.  No matter what you’re doing--solving homework, playing a video game, simply picking out a shirt--all of your actions and decisions relate to your consciousness. But as frequently as we use it, have you ever stopped to ask yourself: What really is consciousness? In this module, we discuss the different levels of consciousness and how they can affect your behavior in a variety of situations. As well, we explore the role of consciousness in other, “altered” states like hypnosis and sleep.

By Linda Bartoshuk and Derek Snyder, University of Florida. Humans are omnivores (able to survive on many different foods). The omnivore’s dilemma is to identify foods that are healthy and avoid poisons. Taste and smell cooperate to solve this dilemma. Stimuli for both taste and smell are chemicals. Smell results from a biological system that essentially permits the brain to store rough sketches of the chemical structures of odor stimuli in the environment. Thus, people in very different parts of the world can learn to like odors (paired with calories) or dislike odors (paired with nausea) that they encounter in their worlds. Taste information is preselected (by the nature of the receptors) to be relevant to nutrition. No learning is required; we are born loving sweet and hating bitter. Taste inhibits a variety of other systems in the brain. Taste damage releases that inhibition, thus intensifying sensations...

By Marissa L. Diener, University of Utah. This module focuses on parenthood as a developmental task of adulthood. Parents take on new roles as their children develop, transforming their identity as a parent as the developmental demands of their children change. The main influences on parenting, parent characteristics, child characteristics, and contextual factors, are described.

By Joel A. Muraco, University of Wisconsin, Green Bay. Each and every one of us has a family. However, these families exist in many variations around the world. In this module, we discuss definitions of family, family forms, the developmental trajectory of families, and commonly used theories to understand families. We also cover factors that influence families such as culture and societal expectations while incorporating the latest family relevant statistics.

By Emily Hooker and Sarah Pressman, University of North Carolina at Chapel Hill, University of Calfornia, Irvine. Our emotions, thoughts, and behaviors play an important role in our health. Not only do they influence our day-to-day health practices, but they can also influence how our body functions. This module provides an overview of health psychology, which is a field devoted to understanding the connections between psychology and health. Discussed here are examples of topics a health psychologist might study, including stress, psychosocial factors related to health and disease, how to use psychology to improve health, and the role of psychology in medicine.

By Robert Bornstein, Adelphi University. Originating in the work of Sigmund Freud, the psychodynamic perspective emphasizes unconscious psychological processes (for example, wishes and fears of which we’re not fully aware), and contends that childhood experiences are crucial in shaping adult personality. The psychodynamic perspective has evolved considerably since Freud’s time, and now includes innovative new approaches such as object relations theory and neuropsychoanalysis. Some psychodynamic concepts have held up well to empirical scrutiny while others have not, and aspects of the theory remain controversial, but the psychodynamic perspective continues to influence many different areas of contemporary psychology.

By Donelson R. Forsyth, University of Richmond. This module assumes that a thorough understanding of people requires a thorough understanding of groups. Each of us is an autonomous individual seeking our own objectives, yet we are also members of groups—groups that constrain us, guide us, and sustain us. Just as each of us influences the group and the people in the group, so, too, do groups change each one of us. Joining groups satisfies our need to belong, gain information and understanding through social comparison, define our sense of self and social identity, and achieve goals that might elude us if we worked alone. Groups are also practically significant, for much of the world’s work is done by groups rather than by individuals. Success sometimes eludes our groups, but when group members learn to work together as a cohesive team their success becomes more certain. People also turn to groups when important decisions must be made, and this choice is justified as long as groups avoid such problems as group polarization and groupthink.

By Don Lucas and Jennifer Fox, Northwest Vista College. Sexuality is one of the fundamental drives behind everyone’s feelings, thoughts, and behaviors. It defines the means of biological reproduction, describes psychological and sociological representations of self, and orients a person’s attraction to others. Further, it shapes the brain and body to be pleasure-seeking. Yet, as important as sexuality is to being human, it is often viewed as a taboo topic for personal or scientific inquiry.

By Ap Dijksterhuis. Radboud University Nijmegen. Unconscious psychological processes have fascinated people for a very long time. The idea that people must have an unconscious is based on the idea that (a) there is so much going on in our brains, and the capacity of consciousness is so small, that there must be much more than just consciousness; and that (b) unless you believe consciousness is causally disconnected from other bodily and mental processes, conscious experiences must be prepared by other processes in the brain of which we are not conscious. Not only logic dictates that action starts unconsciously, but research strongly suggests this too. Moreover, unconscious processes are very often highly important for human functioning, and many phenomena, such as attitude formation, goal pursuit, stereotyping, creativity, and decision making are impossible to fully understand without incorporating the role of unconscious processes.

By Dora Angelaki and J. David Dickman, Baylor College of Medicine. The vestibular system functions to detect head motion and position relative to gravity and is primarily involved in the fine control of visual gaze, posture, orthostasis, spatial orientation, and navigation. Vestibular signals are highly processed in many regions of the brain and are involved in many essential functions. In this module, we provide an overview of how the vestibular system works and how vestibular signals are used to guide behavior.

By Bertram Malle, Brown University. One of the most remarkable human capacities is to perceive and understand mental states. This capacity, often labeled “theory of mind,” consists of an array of psychological processes that play essential roles in human social life. We review some of these roles, examine what happens when the capacity is deficient, and explore the many processes that make up the capacity to understand minds.

By Hannah Boettcher, Stefan G. Hofmann, and Q. Jade Wu, Boston University. In the past century, a number of psychotherapeutic orientations have gained popularity for treating mental illnesses. This module outlines some of the best-known therapeutic approaches and explains the history, techniques, advantages, and disadvantages associated with each. The most effective modern approach is cognitive behavioral therapy (CBT). We also discuss psychoanalytic therapy, person-centered therapy, and mindfulness-based approaches. Drug therapy and emerging new treatment strategies will also be briefly explored.

By Erin I. Smith,California Baptist University.We are bombarded every day with claims about how the world works, claims that have a direct impact on how we think about and solve problems in society and our personal lives. This module explores important considerations for evaluating the trustworthiness of such claims by contrasting between scientific thinking and everyday observations (also known as “anecdotal evidence”). I.

By Robert V. Levine, California State University, Fresno. There are profound cultural differences in how people think about, measure, and use their time. This module describes some major dimensions of time that are most prone to cultural variation.

By Simona Buetti and Alejandro Lleras, University of Illinois at Urbana-Champaign. Vision is the sensory modality that transforms light into a psychological experience of the world around you, with minimal bodily effort. This module provides an overview of the most significant steps in this transformation and strategies that your brain uses to achieve this visual understanding of the environment.

Welcome to Child Growth and Development. This text is a presentation of how and why children grow, develop, and learn. We will look at how we change physically over time from conception through adolescence. We examine cognitive change, or how our ability to think and remember changes over the first 20 years or so of life. And we will look at how our emotions, psychological state, and social relationships change throughout childhood and adolescence.
