As technology advances and offers enjoyable sedentary alternatives to sport, active recreation, and transportation, there is a growing need to understand and harness the drivers of physical activity and exercise among children and adolescents. Determining how youth perceive their physical capabilities and their opportunities and what motivates them to be physically active can provide essential information for teachers, coaches, youth leaders, and program planners who are interested in promoting physical activity. Several well-established and also more recently developed behavioral theories offer numerous avenues to gaining a better understanding of the perceptions and motivation of youth with respect to physical activity and exercise behavior, including the social ecological model, social cognitive theory, self-determination theory, habit theory, dual-process theory, and nudge theory, among others.
Children and adolescents have individual characteristics that influence their perceptions, motivations, and behavior. They also exist within a multilayered ecological context that helps to shape those perceptions, motivations, and behavior. For youth to be sufficiently physically active and thereby help to reach their full potential, the environment must be conducive to consistent routines of physical activity. Such an environment can be designed to provide easily accessible and enjoyable opportunities for youth to fulfill their basic psychological needs for autonomy, relatedness, and competence to be physically active. There is potential for technology to contribute positively toward the design of conducive environments, and toward fostering motivation and enjoyment of exercise and physical activity among children and adolescents.
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.

Gender and cultural diversity are ever-present and powerful in sport, exercise, and performance settings. Our cultural identities affect our behaviors and interactions with others. As professionals, we must recognize and value cultural diversity. Gender and culture are best understood within a multicultural framework that recognizes multiple, intersecting identities; power relations; and the action for social justice. Physical activity participants are culturally diverse in many ways, but in other ways cultural groups are excluded from participation, and especially from power (e.g., leadership roles).
Sport, exercise, and performance psychology have barely begun to address cultural diversity, and the limited scholarship focuses on gender. Although the participation of girls and women has increased dramatically in recent years, stereotypes and media representations still convey the message that sport is a masculine activity. Stereotypes and social constraints are attached to other cultural groups, and those stereotypes affect behavior and opportunities. Race, ethnicity, socioeconomic status, and physical characteristics all limit opportunities in physical activity settings. People who are overweight or obese are particularly subject to bias and discrimination in sport and physical activity. Cultural competence, which refers to the ability to work effectively with people of a different culture, is essential for professionals in sport, exercise, and performance psychology. Not only is it important for individuals to develop their own cultural awareness, understanding, and skills, but we must advocate for inclusive excellence in our programs and organizations to expand our reach and promote physical activity for the health and well-being of all.

Understanding gender and gender differences is a prevalent aim in many psychological subdisciplines. Social psychology has tended to employ a binary understanding of gender and has focused on understanding key gender stereotypes and their impact. While women are seen as warm and communal, men are seen as agentic and competent. These stereotypes are shaped by, and respond to, social contexts, and are both descriptive and prescriptive in nature. The most influential theories argue that these stereotypes develop in response to societal structures, including the roles women and men occupy in society, and status differences between the sexes. Importantly, research clearly demonstrates that these stereotypes have a myriad of effects on individuals’ cognitions, attitudes, and behaviors and contribute to sexism and gender inequality in a range of domains, from the workplace to romantic relationships.
Gestalt psychology is an holistic approach to psychology launched in 1910 by three psychologists: Max Wertheimer, Wolfgang Köhler, and Kurt Koffka. It was conceived to oppose elementary or atomistic psychology, the conception that psychical processes consist of elements whose associations produce the contents experienced in the mind or soul. Instead, Gestalt psychology holds that configurations or, in German, Gestalten, not these hypothetical elements, are the primary material underlying experience. Beginning with research in perception, the Gestalt approach was soon applied to other fields of psychology. Gestalt theory, inspired by field theories in physics, tried to lay a common groundwork for psychology, physiology, and physics. The Gestalt movement originated in Germany, but the three protagonists for personal and political reasons resettled in the United States where the movement became an important force combatting the dominance of behaviorism. The Gestalt approach was especially fruitful in empirical psychology, but it did not fulfill the promise of turning psychology into a unified science based on a common theoretical ground.

Within sporting contexts, goal setting is a commonly used technique that can lead to enhanced performance. Recommendations for goal setting have been widely embraced in sport and performance settings by researchers, practitioners, athletes, and coaches. However, it could be argued that these recommendations are overly simplistic, and that a lack of critical commentary in the sporting literature fails to acknowledge the complexity of goal setting in practice. For example, there has been limited acknowledgement within the applied recommendations of important factors such as personal differences with those individuals setting goals, contextual and environmental factors, and the characteristics of goals being pursed. Equally, the focus of goal setting research and practice has predominantly been on goal progress or goal attainment, thus overlooking the wider benefits of effective goal pursuit on additional aspects such as well-being. Similarly, the interactions between these factors has gained little attention with the academic literature or applied recommendations. This may result in diminished effectiveness of goal setting for athletes, and ultimately lead to sub-optimal performance and well-being.
Critical and comprehensive reviews of the literature are timely and necessary, in order to develop a deeper understanding of goal setting in sport and performance. Combining research from both within sport and from theorists examining goals within other contexts can enhance our understanding of how to promote and support adaptive goal pursuit within sport and performance. Overall, this may lead to more appropriate and useful recommendations for researchers, athletes, coaches, and applied practitioners, ensuring that goal setting can be an effective technique for a range of individuals within sport and performance contexts.

Consciously setting a specific, difficult, challenging goal leads to high performance for four reasons. Specificity results in (1) the choice to focus on goal-relevant activities and to ignore those that are irrelevant. Challenge leads to an increase in (2) effort and (3) persistence to attain the goal. The combination of specificity and difficulty cue (4) the search for strategies to attain the goal. However, for this to occur, an individual or team must have the ability and the situational resources to attain the goal. In addition, the goal must be important; there must be commitment to goal attainment. Finally, feedback must be provided on goal progress so that adjustments can be made, if necessary, regarding effort or strategy for attaining the goal.

Death and loss are universal human experiences, yet understandings of and attitudes toward expressing grief have shifted across time. The earliest psychological conceptualization of grief pathologized “holding on” to the lost object, a notion that has since been rejected in favor of a conception of continuing bonds that can be adaptive in grief. Similarly, early stage theories of grieving suggested a linear progression toward resolution and acceptance of loss, which has been criticized in favor of approaches that allow for natural regulatory processes of attending to the loss and reengaging with a changed world. In sum, grief is no longer regarded solely as looking back on a past life with the deceased but rather is oriented toward creating and reconstructing a meaningful present and future that accommodate the loss and its impact.
Most people respond adaptively to loss by relying on their internal and social support systems. However, a significant subset of grievers struggles with complicated grief, which is characterized by intense longing for the deceased, causes impairment in various life domains, and extends beyond the period of grieving that is considered normal for the population and culture. Grief therapy is most appropriate and advantageous for grievers who self-identify the need for additional support, and this tends to happen among those who are struggling disproportionately. Complicated grief shares features with other common psychiatric diagnoses (e.g., Major Depressive Disorder and Posttraumatic Stress Disorder), as well as being characterized by distinctive separation distress regarding the deceased. Treatment for complicated grief targets the common symptoms among these disorders as well as the grief-specific manifestations of distress that are concentrated on issues of coping, attachment, meaning, and behavior.

Group decisions are ubiquitous in everyday life. Even when decisions are made individually, decision-makers often receive advice or suggestions from others. Thus, decisions are often social in nature and involve multiple group members. The literature on group decision-making is conceptualized as falling along two dimensions: how much interaction or information exchange is allowed among the group members, and how the final decision is made. On one end, group decisions can be made simply by aggregating member preferences or judgments without any interaction among members, with members having no control or say in the final judgment. One the other end, groups’ decisions can involve extensive member interaction and information exchanges, and the final decision is reached by group consensus. In between these two endpoints, various other strategies are also possible, including prediction markets, Delphi groups, and judge–advisor systems. Research has shown that each dimension has different implications for decision quality and process depending on the decision task and context. Research exploring these two dimension has also helped to illuminate those aspects of group decision-making that can lead to better-quality decisions.
Group process refers to the behaviors of the members of small working groups (usually between three and twelve members) as they engage in decision-making and task performance. Group process includes the study of how group members’ characteristics interact with the behavior of group members to create effective or ineffective group performance. Relevant topics include the influences of group norms, group roles, group status, group identity, and group social interaction as they influence group task performance and decision-making, the development and change of groups over time, group task typologies, and decision-making schemes. Relevant group outcomes include group cohesion, process losses and process gains in performance, free riding, ineffective information sharing, difficulties in brainstorming, groupthink, and group polarization. Other variables that influence effective group process include group member diversity, task attractiveness, and task significance. A variety of techniques are used to improve group process.
Gustav Theodor Fechner (b. 1801–d. 1887) is well known to psychologists as the founder of psychophysics, a set of methods for empirically relating measured sensory stimulus to reported sensation. Rich as this field of research has proven to be, especially as detection instruments and recording devices have improved in modern times, Fechner himself would be disappointed to discover that he is remembered merely for psychophysics as psychologists understand it today. To Fechner, those particular methods and approaches were only one part of the domain of psychophysics—outer psychophysics—whereas he envisioned psychophysics (both outer and inner) to be the key to the broadest kind of scientific worldview: the study of the relationship between the material world and the mental world (indeed the spiritual universe; in German, die geistige Welt).
The preface of Fechner’s 1860 masterwork, Elements of Psychophysics, states, “[I]t is an exact theory of the relation of mind to body. . . . As an exact science psychophysics, like physics, must rest on experience and the mathematical connection of those empirical facts that demand a measure of what is experienced or, when such a measure is not available, a search for it.” In that definition, Fechner reveals his view of natural science, and how psychophysics was meant to expand the range of natural science and the scope of its achievements. Fechner’s influence emerged during the mid-19th century, as the physical and medical sciences were achieving great breakthroughs and establishing fundamental and unifying concepts; this was especially true in Germany, including the city where he came to study and remained for the rest of his life, Leipzig. Fechner was one of the most enthusiastic and optimistic believers in unifying concepts of science.
Fechner’s psychophysics gave important impetus to psychometrics and experimental psychology; he also proposed a statistical approach to aesthetics and a “theory of collectives” that pointed toward statistical interpretations of many (perhaps all) areas of experience. In his early career he was a central figure in German physics and an early supporter of the atomic theory of matter as well as Darwinian evolution. His profoundly spiritual ideas, however, were out of step with the science of his time. This aspect of Fechner’s thought is evident in his inner psychophysics, where he searched for the full measure of “what is experienced.”

Within psychology, the term habit refers to a process whereby contexts prompt action automatically, through activation of mental context–action associations learned through prior performances. Habitual behavior is regulated by an impulsive process, and so can be elicited with minimal cognitive effort, awareness, control, or intention. When an initially goal-directed behavior becomes habitual, action initiation transfers from conscious motivational processes to context-cued impulse-driven mechanisms. Regulation of action becomes detached from motivational or volitional control. Upon encountering the associated context, the urge to enact the habitual behavior is spontaneously triggered and alternative behavioral responses become less cognitively accessible.
By virtue of its cue-dependent automatic nature, theory proposes that habit strength will predict the likelihood of enactment of habitual behavior, and that strong habitual tendencies will tend to dominate over motivational tendencies. Support for these effects has been found for many health-related behaviors, such as healthy eating, physical activity, and medication adherence. This has stimulated interest in habit formation as a behavior change mechanism: It has been argued that adding habit formation components into behavior change interventions should shield new behaviors against motivational lapses, making them more sustainable in the long-term. Interventions based on the habit-formation model differ from non-habit-based interventions in that they include elements that promote reliable context-dependent repetition of the target behavior, with the aim of establishing learned context–action associations that manifest in automatically cued behavioral responses. Interventions may also seek to harness these processes to displace an existing “bad” habit with a “good” habit.
Research around the application of habit formation to health behavior change interventions is reviewed, drawn from two sources: extant theory and evidence regarding how habit forms, and previous interventions that have used habit formation principles and techniques to change behavior. Behavior change techniques that may facilitate movement through discrete phases in the habit formation trajectory are highlighted, and techniques that have been used in previous interventions are explored based on a habit formation framework. Although these interventions have mostly shown promising effects on behavior, the unique impact on behavior of habit-focused components and the longevity of such effects are not yet known. As an intervention strategy, habit formation has been shown to be acceptable to intervention recipients, who report that through repetition, behaviors gradually become routinized. Whether habit formation interventions truly offer a route to long-lasting behavior change, however, remains unclear.
Healthy and Pathological Neurocognitive Aging: Spectral and Functional Connectivity Analyses Using Magnetoencephalography

Oscillatory activity present in brain signals reflects the underlying time-varying electrical discharges within and between ensembles of neurons. Among the variety of non-invasive techniques available for measuring of the brain’s oscillatory activity, magnetoencephalography (MEG) presents a remarkable combination of spatial and temporal resolution, and can be used in resting-state or task-based studies, depending on the goals of the experiment.
Two important kinds of analysis can be carried out with the MEG signal: spectral a. and functional connectivity (FC) a. While the former provides information on the distribution of the frequency content within distinct brain areas, FC tells us about the dependence or interaction between the signals stemming from two (or among many) different brain areas.
The large frequency range combined with the good resolution offered by MEG makes MEG-based spectral and FC analyses able to highlight distinct patterns of neurophysiological alterations during the aging process in both healthy and pathological conditions. Since disruption in spectral content and functional interactions between brain areas could be accounted for by early neuropathological changes, MEG could represent a useful tool to unveil neurobiological mechanisms related to the cognitive decline observed during aging, particularly suitable for the detection of functional alterations, and then for the discovery of potential biomarkers in case of pathology.
The aging process is characterized by alterations in the spectral content across the brain. At the network level, FC studies reveal that older adults experience a series of changes that make them more vulnerable to cognitive interferences.
While special attention has been dedicated to the study of pathological conditions (in particular, mild cognitive impairment and Alzheimer’s disease), the lack of studies addressing the features of FC in healthy aging is noteworthy. This area of research calls for future attention because it is able to set the baseline from which to draw comparisons with different pathological conditions.

Age-related hearing loss is heterogeneous. Multiple causes can damage the auditory system from periphery to cortex. There can be changes in thresholds for detecting sound and/or in the perception of supra-threshold sounds. Influenced by trends in neuroscience and gerontology, research has shifted from a relatively narrow modality-specific focus to a broader interest in how auditory aging interacts with other domains of aging. The importance of the connection between sensory and cognitive aging was reported based on findings from the Berlin Aging Study in the mid-1990s. Of the age-related sensory and motor declines that become more prevalent with age, hearing loss is the most common, and it is the most promising as an early marker for risk of cognitive decline and as a potentially modifiable mid-life risk factor for dementia. Hearing loss affects more than half of the population by 70 years of age and about 80% of people over 80 years of age. It is more prevalent in people with dementia than in peers with normal cognition. People with hearing loss can be up to five times more likely to develop dementia compared to those with normal hearing. Evidence from cross-sectional studies has confirmed significant correlations between hearing loss and cognitive decline in older adults. Longitudinal studies have demonstrated that hearing loss is associated with incident cognitive decline and dementia. Various biological, psychological, and social mechanisms have been hypothesized to account for these associations, but the causes remain unproven. Nevertheless, it is widely believed that there is a meaningful interface among sensory, motor, and cognitive dysfunctions in aging, with implications for issues spanning brain plasticity to quality of life. Experimental research investigating sensory-motor-cognitive interactions provides insights into how age-related declines in these domains may be exacerbated or compensated. Ongoing research on auditory aging and how it interfaces with cognitive aging is expected to increase knowledge of the neuroscience of aging, provide insights into how to optimize the everyday functioning of older adults, and inspire innovations in clinical practice and social policy.
