The study of development across the lifespan has traditionally focused on the individual. However, dyadic designs within lifespan developmental methodology allow researchers to better understand individuals in a larger context that includes various familial relationships (husbands and wives, parents and children, and caregivers and patients). Dyadic designs involve data that are not independent, and thus outcome measures from dyad members need to be modeled as correlated. Typically, non-independent outcomes are appropriately modeled using multilevel or structural equation modeling approaches. Many dyadic researchers use the actor-partner interdependence model as a basic analysis framework, while new and exciting approaches are coming forth in the literature. Dyadic designs can be extended and applied in various ways, including with intensive longitudinal data (e.g., daily diaries), grid sequence analysis, repeated measures actor/partner interdependence models, and vector field diagrams. As researchers continue to use and expand upon dyadic designs, new methods for addressing dyadic research questions will be developed.

Dynamic integration theory (DIT) describes emotion development across the lifespan, from childhood to old age. In doing so, DIT draws on a number of perspectives, such as equilibrium theories, theories of cognitive development, and theories of behavioral adaptation, and takes a strong cognitive-developmental view on emotion experience and emotion regulation. Two propositions are at the core of DIT. First, the development of emotion experience and emotion regulation proceeds from simple and automatic reactions to increasingly complex and integrated cognitive-affective structures (i.e., schemas). These cognitive-affective structures can be ordered in terms of increasing levels of cognitive complexity and integration, with integration referring to a person’s ability to acknowledge both positive and negative affect states and to tolerate and reconcile the contradictions and tensions that these states generate. Second, DIT also postulates that the efficiency with which cognitive-affective systems work is a result of the dynamic interplay between contextual variables and person-specific characteristics. Three key factors contribute to this dynamic interplay between person and context: (1) the strength of the affective arousal, (2) the person’s cognitive resources for dealing with different affect states, and (3) pre-existing trait-like dispositions and reaction tendencies that may either hinder or facilitate emotion regulation. Thus, a person’s emotion experience and emotion regulation in a given situation are the product of the dynamic interaction of these factors. Considerable empirical evidence supports the theoretical propositions of DIT, including findings speaking to changes in emotion experience and emotion regulation in later life when declines in cognitive functioning tend to become normative.
Dyslexia, or a reading disability, occurs when an individual has great difficulty at the level of word reading and decoding. Comprehension of text, writing, and spelling are also affected. The diagnosis of dyslexia involves the use of reading tests, but the continuum of reading performance means that any cutoff point is arbitrary. The IQ score does not play a role in the diagnosis of dyslexia. Dyslexia is a language-based learning disability. The cognitive difficulties of dyslexics include problems with recognizing and manipulating the basic sounds in a language, language memory, and learning the sounds of letters. Dyslexia is a neurological condition with a genetic basis. There are abnormalities in the brains of dyslexic individuals. There are also differences in the electrophysiological and structural characteristics of the brains of dyslexics. Hope for dyslexia involves early detection and intervention and evidence-based instruction.

Emotions are multifaceted subjective feelings that reflect expected, current, or past interactions with the environment. They involve sets of interrelated psychological processes, encompassing affective, cognitive, motivational, physiological, and expressive or behavioral components. Emotions play a fundamental role in human adaptation and performance by improving sensory intake, detection of relevant stimuli, readiness for behavioral responses, decision-making, memory, and interpersonal interactions. These beneficial effects enhance human health and performance in any endeavor, including sport, work, and the arts. However, emotions can also be maladaptive. Their beneficial or maladaptive effects depend on their content, time of occurrence, and intensity level. Emotional self-regulation refers to the processes by which individuals modify the type, quality, time course, and intensity of their emotions. Individuals attempt to regulate their emotions to attain beneficial effects, to deal with unfavorable circumstances, or both. Emotional self-regulation occurs when persons monitor the emotions they are experiencing and try to modify or maintain them. It can be automatic or effortful, conscious or unconscious. The process model of emotion regulation provides a framework for the classification of antecedent- and response-focused regulation processes. These processes are categorized according to the point at which they have their primary impact in the emotion generative process: situation selection (e.g., confrontation and avoidance), situation modification (e.g., direct situation modification, support-seeking, and conflict resolution), attentional deployment (e.g., distraction, concentration, and mindfulness), cognitive change (e.g., self-efficacy appraisals, challenge/threat appraisals, positive reappraisal, and acceptance), and response modulation (e.g., regulation of experience, arousal regulation, and expressive suppression). In addition to the process model of emotion regulation, other prominent approaches provide useful insights to the study of adaptation and self-regulation for performance enhancement. These include the strength model of self-control, the dual-process theories, the biopsychosocial model, the attentional control theory, and the individual zones of optimal functioning model. Based on the latter model, emotion-centered and action-centered interrelated strategies have been proposed for self-regulation in sport. Within this framework, performers identify, regulate, and optimize their functional and dysfunctional emotions and their most relevant components of functional performance patterns.

The term empathy has been used as a label for a broad range of phenomena, including feeling what another person is feeling, understanding another person’s point of view, and imagining oneself in another person’s situation. However, perhaps the most widely researched phenomenon that goes by this label involves an other-oriented emotional state that is congruent with the perceived welfare of another person. The feelings associated with empathy include sympathy, tenderness, and warmth toward the other person. Other variations of empathic emotions have been investigated too, including empathic joy, empathic embarrassment, and empathic anger. The term altruism has also been used as a label for a broad range of phenomena, including any type of helping behavior, personality traits associated with helpful persons, and biological influences that spur protection of genetically related others. However, a particularly fruitful research tradition has focused on altruism as a motivational state with the ultimate goal of protecting or promoting the welfare of a valued other. For example, the empathy–altruism hypothesis claims that empathy (construed as an other-oriented emotional state) evokes altruism (construed as a motivational state). Empathy and altruism, regardless of how they are construed, have important consequences for understanding human behavior in general, and for understanding social relationships and well-being in particular.

Episodic future thinking refers to the ability to imagine or simulate experiences that might occur in an individual’s personal future. It has been known for decades that cognitive aging is associated with declines in episodic memory, and recent research has documented correlated age-related declines in episodic future thinking. Previous research has considered both cognitive and neural mechanisms that are responsible for age-related changes in episodic future thinking, as well as effects of aging on the functions served by episodic future thinking. Studies concerned with mechanism indicate that multiple cognitive mechanisms contribute to changes in episodic future thinking during aging, including episodic memory retrieval, narrative style, and executive processes. Recent studies using an episodic specificity induction—brief training in recollecting episodic details of a recent experience—have proven useful in separating the contributions of episodic retrieval from other non-episodic processes during future thinking tasks in both old and young adults. Neuroimaging studies provide preliminary evidence of a role for age-related changes in default and executive brain networks in episodic future thinking and autobiographical planning. Studies concerned with function have examined age-related effects on the link between episodic future thinking and a variety of processes, including everyday problem-solving, prospective memory, prosocial intentions, and intertemporal choice/delay discounting. The general finding in these studies is for age-related reductions, consistent with the work on mechanisms that consistently reveals reduced episodic detail in older adults when they imagine future events. However, several studies have revealed that episodic simulation nonetheless confers some benefits for tasks tapping adaptive functions in older adults, such as problem-solving, prospective memory, and prosocial intentions, even though age-related deficits on these tasks are not eliminated or reduced by episodic future thinking.

Erythocyte sedimentation rate (ESR) is one of the oldest measures of inflammation. It is used extensively in clinical medicine and has shown some utility in biomedical research. It is a nonspecific inflammation assay, and although it is less sensitive than more modern measures such as C-reactive protein, it is a useful measure in chronic illnesses.
In general, ESR increases with age and appears to be a biomarker of aging in general. It predicts both cardiovascular disease (CVD) and cancer and is elevated in autoimmune disorders such as rheumatoid arthritis. Further, it predicts mortality both in the general population and in those with chronic illnesses such as CVD and cancer, independent of other indicators of illness severity.
Interestingly, ESR is not associated with anxiety or general measures of distress but is consistently associated with measures of depression and suicidal ideation. Further, the effect of depressive symptoms on mortality appears to be mediated through increases in ESR.
Studies of the relationship between stress and ESR have been less consistent, primarily because early studies were largely cross-sectional and in small samples. Studies using more modern, longitudinal analyses in larger samples may show more consistent results, especially if multilevel modeling was used that examined within-person changes in ESR in response to stress. Given that other large, longitudinal studies, such as the Baltimore Longitudinal Study on Aging, the Rotterdam Study, The Reykjavik Cohort Study, and Women’s Healthy Ageing Study have included ESR in their biomedical assays, it should be possible to analyze existing data to examine how psychosocial factors influence inflamm-aging in humans.

The field of sport, exercise, and performance psychology (SEPP) has evolved over the past 100 plus years. SEPP includes professional consultants, teachers, researchers, and students from diverse educational and training backgrounds. Persons primarily from the merging of sport science, kinesiology, and professional psychology have shaped SEPP into what it is today. Client populations typically served include athletes, coaches, and exercisers, and more recently, performing artists (musicians, singers, dancers), businesspersons, sports medicine professionals, and military personnel.
These people and phenomena have fashioned an ethical climate that is generally similar to—but in various ways different from—mainstream psychology. While the ethical values and codes of organizations like the American Psychological Association (APA) and the Association of Applied Sport Psychology (AASP) are generally comparable, the perceptions and application of these values and codes in SEPP realms may not match; this is due to the different histories of its membership, as well as the sometimes unusual work demands and atypical settings and circumstances in which SEPP persons function.
For both mainstream psychology and SEPP professionals, developments in technology and social media communications have presented ethical dilemmas for many who seek to maintain regular contact with their clientele. These issues, such as the use of technology in consulting, emphasize the importance of core ethical tenets such as privacy, confidentiality, and competence, among others, in the growing area of telehealth. In view of the rather unique ethical climate within SEPP, teaching applied ethics via classroom discussion, continued education, and sourcebooks is essential. To date, there appears to be a lack of continuity in the training and supervision of SEPP students and young professionals with respect to ethical decision making. This presents both a challenge and an opportunity to the current and next generation of scholars, researchers, and practitioners.

It is important for sport and exercise psychology (SEP) professionals to demonstrate that the interventions they employ make a difference. Assessing the degree of an intervention’s effectiveness depends first and foremost on the nature and scope of the intervention (i.e., the objective of the intervention) and its targeted group. Traditionally, interventions have been quite varied between the fields of sport psychology and exercise psychology; a common thread however, can be seen as an enhancement of the sport or exercise experience, along with an attempt to help the individual better self-regulate engagement with the targeted behavior or mindset. The central aim of enhancing the experience and increased self-regulation is oriented toward performance enhancement within sport psychology interventions, whereas within exercise psychology interventions the orientation is toward physical-activity adoption and better exercise program adherence. Although the two fields may have different objectives, it can be argued that sport psychology interventions—specifically psychological skills training (PST) interventions—can inform SEP professionals’ research and applied practices with both the sport and exercise populations.
Psychological skills training includes the strategies and techniques used to develop psychological skills, enhance sport performance, and facilitate a positive approach to competition. Since the early 1980s, a growing body of evidence has supported that the PST interventions SEP professionals employ do make a difference. In particular, evidence from research in sport contexts supports the use of a multimodal approach to PST interventions—combining different types of psychological strategies (e.g., goal-setting, self-talk, imagery, relaxation)—because a multimodal approach has demonstrated positive effects on both psychological skills and sport performance. The research investigating the effectiveness of PST interventions in enhancing performance has primarily centered on adult athletes who compete at competitive or elite levels. Elite athletes are certainly important consumers of SEP services; however, SEP professionals have rightfully challenged researchers and practitioners to target other consumers of SEP services who they argue are as deserving of PST as elite athletes. For example, young athletes and coaches are two populations that have traditionally been overlooked in the PST research. PST interventions targeting young athletes can help them to develop (at the start of their sporting careers) the type of psychological skills that facilitate a positive approach to competition and better abilities to self-regulate their emotional responses to stressful competitive situations. Coaches are also performers with unique needs who could benefit from PST interventions. Researchers have begun to target these two populations and the results might be considered the most intriguing aspects of the current PST literature. Future research related to PST interventions should target exercise populations. Exercise professionals often operate as coaches in healthy behavior change (e.g., strength and conditioning coaches, personal trainers, etc.) and as such should also employ, and monitor responses to, PST.
To facilitate further development and growth of PST intervention research in both sport and exercise settings, SEP professionals are encouraged to include a comprehensive evaluation of program effectiveness. In particular, four major areas to consider when evaluating PST programs are (a) the quality of the PST service delivery (e.g., the knowledge, delivery style, and characteristics of the SEP professional); (b) assessment of the sport psychological strategies participants used as a result of the PST program; (c) participants’ perceptions of the influence of the PST program on their psychological skills, performance, and enjoyment; and (d) measurement of participants psychological skills, performance, and enjoyment as a result of the PST program.

Edmund V. Cowdry’s Problems of Ageing (1939), the first U.S. handbook in gerontology, spurred efforts to systematize and communicate data and hypotheses in a “discouragingly difficult field,” as one of the volume’s contributors put it. Researchers, educators, and practitioners subsequently published handbooks of aging to share basic concepts, norms, and metaphors—and eventually to construct theories.
Compared to theoretical constructs that animate African American studies, paradigms that inform inquiries into sex and gender, and queer theory-building, research on aging is sustained by few evidence-based, methodologically robust, heuristic theories. No single construct yet seizes the gerontological imagination. Analyzing notable handbooks reveals that the modern history of ever-emerging gerontological theory building went through three phases.
First, attempts to formulate Big Theories of Aging resulted in more disappointments than scientific advances. In the second phase, researchers on aging set more modest aims, often giving priority to methodological innovation, but failed to promote consilience in a data-rich, theory-poor arena. Psychological theories, pertaining to lifespan development, merit special attention in the third phase, because they proved useful to biomedical and social scientists doing research on aging.

Everyday salivary cortisol is a popular biomarker that is uniquely suited to address key lifespan developmental questions. Specifically, it can be used to shed light on the time-varying situational characteristics that elicit acute stress responses as individuals navigate their everyday lives across the adult lifespan (intraindividual variability). It is also well suited to identify more stable personal characteristics that shape the way that individuals appraise and approach the stressors they encounter across different life phases (interindividual differences). And it is a useful tool to disentangle the mechanisms governing the complex interplay between situational and person-level processes involving multiple systems (gain-loss dynamics). Applications of this biomarker in areas of functioning that are core to lifespan developmental research include emotional experiences, social contextual factors, and cognition. Methodological considerations need to involve careful thought regarding sampling frames, potential confounding variables, and data screening procedures that are tailored to the research question at hand.

Research in psychotherapy has developed a number of treatments, numbering well over 300, that have a strong evidence base. These treatments can be applied to a broad range of psychiatric disorders (e.g., depression, anxiety, schizophrenia, and others) as well as other sources of impairment in psychological functioning among children, adolescents, and adults. This article provides an overview of evidence-based psychotherapies, including current advances in how treatments are applied. Examples of treatments for depression and autism spectrum disorder are provided to illustrate the diversity of procedures in use and how they are applied. Key challenges related to evidence-based psychotherapies are highlighted, and these include disseminating the research findings, so that effective treatments are being used in clinical practice, and devising novel ways of delivering treatment to reach the large number of individuals who are in need of psychological services but do not yet receive care.

Physical activity is essential for optimal human functioning. However, the emergence of modern lifestyle conveniences has contributed to the increased prevalence of sedentary behavior. As a result, the psychobiological nature of physical activity and the positive impact of physical activity on body and brain communication has prompted investigators to utilize a breadth of research strategies and techniques to identify physical activity regimes, associated mental health benefits, and the plausible mechanisms that explain the mental health adaptations. Furthermore, investigators have provided evidence supporting a number of mechanisms that at least partially explain the psychological adaptations to acute (a single bout) and chronic (long-term) physical activity intervention. Through these efforts, the observed efficacy of physical activity as a potential therapeutic intervention strategy to ameliorate the most prevalent mental disorders (i.e., anxiety, depression, bipolar disorder, and schizophrenia), and to enhance mental illness-related and age-related impairments of cognitive function has received some attention in the literature and will likely lead to clarity and confidence for clinical use.
There is no doubt that exercise, a vital health-promoting activity, regardless of health status, produces numerous well-established physical, functional, and mental health benefits. Many people, however, do not adhere to medical recommendations to exercise consistently, especially if they have chronic illnesses. Put forth to explain this conundrum are numerous potential explanatory factors. Among these are mental health correlates such as anxiety, fear, fatigue, pain, motivation, and depression, as well as various self-efficacy perceptions related to exercise behaviors, which may be important factors to identify and intervene upon in the context of promoting adherence to physical activity recommendations along with efforts to reduce the cumulative health and economic burden of exercise non-adherence among the chronically ill and those at risk for chronic illnesses.

Terror management theory (TMT) posits that the uniquely human awareness of death engenders potentially debilitating existential terror that is “managed” by subscribing to cultural worldviews providing a sense that life has meaning as well as opportunities to obtain self-esteem, in pursuit of psychological equanimity in the present and literal or symbolic immortality in the future. In empirical support of TMT, research has demonstrated that: self-esteem serves to buffer anxiety in general, and about death in particular; reminders of death increase defense of the cultural worldview and efforts to bolster self-esteem; threats to the cultural worldview or self-esteem increase the accessibility of implicit death thoughts; conscious and non-conscious thoughts of death instigate qualitatively different defensive processes; death reminders increase hostility toward people with different beliefs, affection for charismatic leaders, and support for political and religious extremism; and death reminders magnify symptoms of psychological disorders.

Experience-sampling methodology (ESM) captures everyday events and experiences during, or shortly after, their natural occurrence in people’s daily lives. It is typically implemented with mobile devices that participants carry with them as they pursue their everyday routines, and that signal participants multiple times a day throughout several days or weeks to report on their momentary experiences and situation. ESM provides insights into short-term within-person variations and daily-life contexts of experiences, which are essential aspects of human functioning and development. ESM also can ameliorate some of the challenges in lifespan-developmental methodology, in particular those imposed by age-comparative designs. Compared to retrospective or global self-reports, for example, ESM can reduce potential non-equivalence of measures caused by age differences in the susceptibility to retrospective memory biases. Furthermore, ESM maximizes ecological validity compared to studies conducted in artificial laboratory contexts, which is a key concern when different age groups may differentially respond to unfamiliar situations. Despite these strengths, ESM also bears significant challenges related to potential sample selectivity and selective sample attrition, participants’ compliance and diligence, measurement reactivity, and missing responses. In age-comparative research, these challenges may be aggravated if their prevalence varies depending on participants’ age. Applications of ESM in lifespan methodology therefore require carefully addressing each of these challenges when planning, conducting, and analyzing a study, and this article provides practical guidelines for doing so. When adequately applied, experience sampling is a powerful tool in lifespan-developmental methodology, particularly when implemented in long-term longitudinal and cross-sequential designs.

Family systems therapy seeks to alter the structure or processes of a family for the purposes of reducing distress in one or more persons and improving the ability of the family to meet members’ needs. Building from a general systems paradigm, family systems therapy recognizes that family structures shift over time as they respond to members’ developmental processes and broader system demands. As members enter and exit or change capacity, and as external stressors arise, the family typically uses adaptive processes to demonstrate resilience. Family systems therapy is useful when the family struggles to adapt, or the adaptation strategy further stresses the family.
Multiple models of family systems therapies offer variations in intervention approaches but have common tenets. Major models include Ackerman’s early psychodynamics model, transgenerational models of family therapy, structural family therapy, strategic family therapy, and communications approaches to family therapy. Models vary in their recommended roles for the therapist, strategies for therapist and family, and the salience of immediate versus longer-term goals. Family systems therapies conceptualize family interactions as complex, reciprocal, open, self-organizing, adaptive, social constructionist, and meaning-making.
Family systems therapy also can be used with systems larger than families, such as schools or organizations, or to understand cultural phenomena. The field of marriage and family therapy has defined competencies for practice, training requirements, and licensure standards and established national and international professional organizations.
Forensic psychology in the 21st century entails the application of psychology to all aspects of the criminal justice process. Forensic psychologists, therefore, are engaged in the theorization of offending, offender profiling, the psychology of testimony, investigative interviewing, the psychology of juries and judges, and psychological approaches to the punishment and treatment of offenders. Historically, however, forensic psychology, has been narrower in scope.
Founded principally in Europe during the late 19th century as a response to the reform of criminal procedure and research on suggestion, which undermined confidence in witness credibility, forensic psychology was initially pursued by jurists and psychiatrists eager to understand the behavior of all those involved in the criminal justice process. While this ambition was pursued piecemeal by jurists throughout the early 20th century in their studies of guilty knowledge, judges, jurors, and investigators, the exigencies of the courtroom, soon saw the field become focused on the psychology of the witness, particularly the juvenile witness. Important, in this regard were the efforts of both European and American experimental psychologists, whose precarious position within universities at the fin de siècle saw them look for real-world applications for psychology and led them to campaign voraciously for the inclusion of psychological knowledge and psychological expertise in legal proceedings.
Competition between several disciplines, including law, psychology, psychiatry, and pedagogy, over the role of psychological expert made the professionalization of this field difficult up until the Second World War. During the late 1940s and 1950s, however, not only did forensic psychology increasingly become the exclusive purview of psychologists, but the discipline’s scope began to expand. Notable in this regard was offender profiling, which emerged from the psychological analysis of war criminals and the application of the insights gained here to several high-profile criminal cases in the United States.
Philosophical functionalism, as distinct from the psychological school of functionalism that enjoyed popularity around the turn of the 20th century, is a theory about the nature of mental states. That is, functionalism offers an account of which conditions must be satisfied for something to count as a belief, or a desire, or a pain, or an itch, or a fear, or a memory. Functionalism is thus a metaphysical doctrine about mental states, that is, a doctrine concerning what makes something a mental state. “Metaphysical,” in this context, should not be taken to suggest anything mysterious. Chemistry is a metaphysical doctrine in just the same sense as functionalism: it is a theory that offers an account of which conditions must be satisfied for something to count as, say, a pure chemical substance rather than a mixture. As philosophical theories go, functionalism has been fantastically successful. Its contemporary form traces to seminal work that H. Putnam initiated in the 1960s, and it remains in early 21st century the most widely accepted theory of the nature of mental states among philosophers in the Anglo tradition.
According to functionalism, the conditions necessary and sufficient for something to be a mental state are specified in terms of functional role. Functionalists have disagreed about the correct basis on which functional descriptions of mental states should rest, with the result that functionalism is better conceived as a family of closely related theories about the nature of mental states rather than a single uniform view. Briefly, the idea of functional role can be usefully illustrated by consideration of an artifact, such as a corkscrew, the nature of which is defined in terms of the function of removing corks. What it is to be a corkscrew is to perform this functional role. Likewise, the functionalist claims, what it is to be a mental state is to perform the functional role characteristic of a belief, or a desire, or a pain, and so on.

With the gambling market continuously shifting and evolving, one form of gambling has uninterruptedly remained a staple in most cultures. Sports wagering has been and remains one of the most popular forms of gambling, especially among males. With the increase in the gambling market, sports wagering has also grown into the online gambling and fantasy sports wagering markets. These escalations in popularity have brought substantial revenue to sports wagering operators and have influenced government officials, policymakers, legislation researchers, the media, and the general public. There are two major groups of issues that surround sports wagering: sports wagering as an economic and tax-generating entity and the integrity of the game. More recently, a concern over problem gambling from a public health perspective has evolved. It is equally important that these issues be considered when creating or changing legislation around sports wagering.
