The brain’s default network (DN) has received considerable interest in the context of so-called “normal” and pathological aging. Findings have generally been couched in support of a pessimistic view of brain aging, marked by substantial loss of structural brain integrity accompanied by a host of impairments in brain and cognitive function. A critical look at the literature, however, reveals that the standard loss of integrity, loss of function (LILF) view in normal aging may not necessarily hold with respect to the DN and the internally guided functions it supports. Many internally guided processes subserved by the DN are preserved or enhanced in cognitively healthy older adults. Moreover, differences in motivational, contextual, and physiological factors between young and older adults likely influence the extant neuroimaging and cognitive findings. Accordingly, normal aging can be viewed as a series of possibly adaptive cognitive and DN-related alterations that bolster cognitive function and promote socioemotional well-being and stability in a stage of life noted for change. On the other hand, the available evidence reveals strong support for the LILF view of the DN in neurodegenerative disorders, whereby syndromes such as Alzheimer’s disease (AD) and semantic dementia (SD), characterized by progressive atrophy to distinct DN subsystems, display distinct aberrations in autobiographical and semantic cognition. Taken together, these findings call for more naturalistic, age-appropriate, and longitudinal paradigms when investigating neurocognitive changes in aging and to adequately assess and control for differences in non-neural factors that may obscure “true” effects of normal and pathological aging. A shift in the framework with which age-related alterations in internally guided cognition are interpreted may shed important light on the neurocognitive mechanisms differentiating healthy and pathological aging, leading to a more complete picture of the aging brain in all its complexity.

Considerable debate has arisen about whether brain activity in elite athletes is characterized by an overall quieting, or neural efficiency in brain processes, or whether elite performance is characterized by activation of two simultaneous networks. One network exercises cognitive control using increased theta activation of premotor and cingulate gyrus, whereas the second reduces alpha activation in an inhibitory network that prevents the intrusion of debilitating thoughts emanating from the temporal lobe and other areas. Also, there is controversy about how a long-duration “quiet eye” (QE) can fit within a single efficient neural system, or whether a dual system where both increased cognitive control and reduced inhibitory processes has advantages. The literature on neural efficiency, the QE, and theta cognitive control, suggest that a long-duration QE promotes both an increase in theta band activation of the medial prefrontal cortex and anterior cingulate and reduced activation and inhibition of the temporal regions during high-pressure situations when a high level of focused, cognitive control is essential.
The Roles of Psychological Stress, Physical Activity, and Dietary Modifications on Cardiovascular Health Implications
Chun-Jung Huang, Matthew J. McAllister, and Aaron L. Slusher
Psychological stress disorders, such as depression and chronic anxiety contribute to increased risk of cardiovascular disease and mortality. Acute psychological and physical stress exacerbate the activity of sympathetic-adrenal-medullary system, resulting in the elevation of cardiovascular responses (i.e., heart rate and blood pressure), along with augmented inflammation and oxidative stress as major causes of endothelial and metabolic dysfunction. The potential health benefits of regular physical activity mitigate excessive inflammation and oxidative stress. Along with physical exercise, complementary interventions, such as dietary modification are needed to enhance exercise effectiveness in improving these outcomes. Specifically, dietary modification reduces sympathetic nervous system activity, improve mitochondrial redox function, and minimize oxidative stress as well as chronic inflammation.
Psychological research on safety at work aims at understanding people’s attitudes and behaviors in relation to hazards for their own and others’ health and well-being. Important safety-related behaviors are safety compliance and safety participation, which address rule-following and proactive safety improvements. These behaviors are influenced by individual cognitive and motivational processes as well as team processes, such as coordination and communication. Relevant antecedents of these processes are characteristics of the job (e.g., job demands), the individual (e.g., risk propensity), the team (e.g., leadership), and the organization (e.g., organizational culture). How individuals and teams are supported in adequately handling hazards also depends on the safety management systems set up in their organizations. Important components of such management systems are, for instance, safety training and incident reporting and investigation. Interventions aimed at improving safety always have to consider cultural factors in the organization, which impact attitudes toward risk and uncertainty.
Schema therapy has evolved since the late 1980s as an efficacious and increasingly widely used psychotherapeutic treatment for personality disorders and many other complex disorders that correlate with underlying maladaptive schemas. Only recently, attention among clinical geropsychologists has been growing for the application of schema therapy in older adults. Schema therapy is very feasible for both therapists and older patients. Schema therapy is an integrative psychotherapy, which draws on the cognitive-behavioral, attachment, psychodynamic, and emotion-focused traditions. In this treatment model, early maladaptive schemas are considered core elements of persistent and pervasive psychopathology, including personality disorders. The goal of treatment is to decrease the impact of maladaptive schemas and to replace negative coping responses and maladaptive schema modes with more healthy alternatives so that patients succeed in getting their core emotional needs met. The emerging attention for schema therapy in older adults is in line with the increased attention for personality disorders in later life, and also with the maturing field of psychotherapy for older adults. The first scientific evidence for the feasibility and the effectiveness of schema therapy has recently been shown. Despite these developments, much work is still to be done. The question is whether schema theory, which was developed for adults in young and middle adulthood, equally applies to those in later life. Although the first tests of effectiveness of schema therapy in older adults are encouraging, age-specific adaptations of existing therapy protocols, both for individual and group schema therapy, are wanted. Furthermore, the research that has been conducted so far has focused on the young-old. Especially for the growing and highly complex group of oldest-old patients, the development of feasible and effective schema-based interventions is needed. Integrating age-specific moderators for change, such as wisdom enhancement, attitudes to aging, and integrating the action of positive schemas, deserves recommendation.

There are many approaches to psychotherapy, commonly called “schools” or “theories.” These schools range from psychoanalytic, to variations of insight- and conflict-based approaches, through behavioral and cognitive behavioral approaches, to humanistic/existential approaches, and finally to integrative and eclectic approaches. Different and seemingly new approaches typically have been informed by older and more established ones. For instance, cognitive behavioral therapy (CBT), one of the more widely used approaches, evolved from traditional behavior therapy but has become sufficiently distinct by adding its own complex variations so as functionally to represent an approach of its own.
New approaches abound both in number and in complexity. Modern clinicians have had to become increasingly widely read and creative in trying to understand the ways in which patients may be helped. The sheer number of approaches, which has climbed into the hundreds, has challenged the field to find ways of ensuring that the treatments presented are effective. The advent of Evidence Based Practices (EBP) throughout the healthcare fields has placed the responsibility on those who advocate for particular types of treatment scientifically to demonstrate their efficacy and effectiveness. While this movement has brought standards to the field and has offered some assurance that psychotherapy is usually helpful, there remains much debate about whether the many different schools produce different results from one another. The debate about how best to optimize positive effects of psychotherapy continues, and there remain many questions to be asked of psychotherapy theories and of research on these approaches.
In the second half of the 19th century, the study of the phenomenon of the dream was undertaken with “scientific” method, by physicians, physiologists, and psychiatrists before the birth of the “myth” advanced by Freud who claimed for psychoanalysis the birthright of the psychological study of dreams. The article highlights the long and varied process of obtaining scientific knowledge of dreams and the dreaming process, and sheds light on researchers and traditions that have not received as much attention as they should have.

This article provides an overview of screening adolescents for substance use, misuse, and substance use disorders. It covers the practical and empirical considerations when working with youth around issues of drugs and alcohol. Four reliable and valid screening tools are discussed: Alcohol Use Disorders Identification Test (AUDIT), CRAFFT, Rutgers Alcohol Problem Index (RAPI), and Problem-Oriented Screening Instrument for Teenagers (POSIT). The tools and techniques are drawn from evidence-based theoretical frames and practices, including close attention to the recent adolescent (Screening, Brief Intervention, Referral, and Treatment (SBIRT) resources.

Active and stored mental representations of the self include both global and specific qualities as well as conscious and nonconscious qualities. Semantic and episodic memory both contribute to a self that is not a unitary construct comprising only the individual as he or she is now, but also past and possible selves. Self-knowledge may overlap more or less with others’ views of the self. Furthermore, mental representations of the self vary whether they are positive or negative, important, certain, and stable. The origins of the self are also manifold and can be considered from developmental, biological, intrapsychic, and interpersonal perspectives. The self is connected to core motives (e.g., coherence, agency, and communion) and is manifested in the form of both personal identities and social identities. Finally, just as the self is a product of proximal and distal social forces, it is also an agent that actively shapes its environment.

Self-talk has been studied from the earliest days of research in experimental psychology. In sport psychology, the cognitive revolution of the 1970s led researchers and practitioners to explore the ways in which self-talk affects performance. Recently, a clear definition of self-talk that distinguishes self-talk from related phenomena such as imagery and gestures and describes self-talk has emerged. Self-talk is defined as the expression of a syntactically recognizable internal position in which the sender of the message is also the intended received. Self-talk may be expressed internally or out loud and has expressive, interpretive, and self-regulatory functions. Various categories of self-talk such as self-talk valence, overtness, demands on working memory, and grammatical form have all been explored.
In the research literature, both instructional and motivational self-talk have been shown to enhance performance. Negative self-talk increases motivation and performance in some circumstances but is generally detrimental to sport performance. Matching self-talk to the task (e.g., using motivational self-talk for gross motor skills such as power lifting) can be a useful strategy, although findings have been inconsistent, perhaps because many individual sport performances involve diverse sport tasks that include both fine and gross motor skills. Research on athletes’ spontaneous self-talk has lagged behind experimental research due in large part to measurement challenges. Self-talk tends to vary over the course of a contest, and it can be difficult for athletes to accurately recall. Questionnaires have allowed researchers to measure typical or “trait” self-talk. Moment-by-moment or “state” self-talk has been assessed by researchers observing sport competitions. Descriptive Experience Sampling has been used to study self-talk in golf, a sport that has regular breaks in the action. Some researchers have used fMRI and other brain assessment tools to examine brain function and self-talk, but current brain imaging technology does not lend itself to use in sport settings. The introduction of the sport-specific model of self-talk into the literature provides a foundation for ongoing exploration of spontaneous (System 1) self-talk and intentionally used (System 2) self-talk and highlights factors related to self-talk and performance such as individual differences (personal factors) and cultural influences (contextual factors).

Primate societies are unusually complex compared to those of other animals, and the need to manage such complexity is the main explanation for the fact that primates have unusually large brains. Primate sociality is based on bonded relationships that underpin coalitions, which in turn are designed to buffer individuals against the social stresses of living in large, stable groups. This is reflected in a correlation between social group size and neocortex size in primates (but not other species of animals), commonly known as the social brain hypothesis, although this relationship itself is the outcome of an underlying relationship between brain size and behavioral complexity. The relationship between brain size and group size is mediated, in humans at least, by mentalizing skills. Neuropsychologically, these are all associated with the size of units within the theory of mind network (linking prefrontal cortex and temporal lobe units). In addition, primate sociality involves a dual-process mechanism whereby the endorphin system provides a psychopharmacological platform off which the cognitive component is then built. This article considers the implications of these findings for the evolution of human cognition over the course of hominin evolution.
Categorization is a process whereby we make sense of the world around us by separating things into different classes or groups. When we learn which categories that objects belong to, we also learn about relationships between those objects. Social categorization involves applying that same process to people, including ourselves. It is not only a cognitive process for understanding and explaining the world, but it is part of the way we organize the world. That is, the groups we belong to such as genders, ethnicities, religions, and nations are based on social categories, and thus phenomena such as stereotyping and person perception rest on social categorization. The study of social categorization has drawn heavily on the study of object categorization and many of the core insights from that field are relevant, but there are also some important differences that suggest social categorization is more, indeed much more, than object categorization. The first key difference is that social categories, unlike object categories, are made up of people who can choose to unite or divide. Social categorization can help us not only to understand why other people are similar to each other and different from us but also to predict when they will be similar and different to us. The second key difference is that when we categorize ourselves, we learn who we can cooperate with, who shares our goals and interests, and who we might cooperate with. It is hard to imagine effective human functioning without the abilities that social categorization grants us.
Social comparison activity is one of the most important spheres of human functioning; it is necessary for appraising where one stands within his or her community and for establishing viable routes for connecting with others. Social comparison is thus a critical psychological phenomenon essential to understanding both social behavior and formation of identity. To this end, individuals look to similar others to evaluate their own abilities and opinions, look to those better than themselves for inspiration and guidance, and evaluate others depending on similarities and distinctions with the self. In addition, they evaluate their own position in life with reference to other’s positions, look to others for information about social norms and for clues about how to behave, and experience feelings toward others based on implications of mutual differences for their relationship. This renders the nature of social comparisons complex; they take horizontal forms that focus on connections or distinction, as well as vertical forms that focus on superiority or inferiority. Moreover, they may be experienced through interaction, subjectively constructed in one’s mind, or deliberately orchestrated in order to impact others.
Complexities of social comparison activity are commensurate with multiple functions that they serve. First, people compare with others in order to gain self-knowledge and reduce uncertainty. Comparisons that fulfill this function typically occur with similar others, are biased toward comparing with those slightly better off, and are sensitive to diagnosticity that information about others carries for oneself. Second, people compare with others in order to self-enhance and protect well-being. Comparisons that fulfill this function often involve contrasting oneself from those worse off, although they can also involve perceiving similarities with superior others, especially when these are role models or close others. Third, people compare in order to self-improve, namely, boost their skills and abilities. Such comparisons typically occur with others that are better, yet similar in relevant attributes, and in domains that leave room for personal progress. Fourth and final, people compare in order to connect socially with others. Such comparisons occur through regular social interaction as individuals emphasize mutual similarities, through creation of comparisons to protect or embolden others, and through selection of social identities that maximize a sense of group belonging.

Theories of social gerontology have progressed from a focus on individuals’ later-life decline to theories that emphasize the intra- and interindividual variability of later-life experiences and the ways in which such heterogeneity is conditioned by social structural, cultural, and interpersonal factors that often begin in childhood and continue to shape individuals and members of their social networks across the life course. Consistent with theories across the sciences, theories of social gerontology predict and explain real-world experiences. In the case of social gerontology, the goals of theory address a wide array of phenomena, ranging from individuals’ attitudes and motivations, social networks and social support, the actions and functions of formal organizations, the embodiment of cultural norms and stereotypes, social determinants of health, and sources of inequality throughout the life course.. As the field of social gerontology has developed, theories in the field have shown increasing complexity, particularly regarding the roles of early life course experiences, social structural positions, and interpersonal relations in explaining variations in well-being, longevity, and the quality of life across the lifespan. As part of this increased complexity, social gerontology has become increasingly cross-disciplinary, spanning disciplines such as sociology, psychology, biology, anthropology, public health, medicine, and engineering, with a strong emphasis on how each discipline can contribute to developing principles that transcend individual fields. These integrative theories of social gerontology are crucial to developing comprehensive approaches to improving the health and well-being of individuals throughout the life course. Theories of social gerontology help us comprehensively understand the aging process by emphasizing individual characteristics, social relationships, and the larger cultural contexts in which individuals’ lives are embedded.

Social isolation refers to the objective lack of social integration. Loneliness, in contrast, refers to the perceived lack of social integration. Loneliness has serious consequences for the well-being of aging persons. Individuals who feel lonely tend to have poorer health, less autonomy, and lower subjective well-being than individuals who do not feel lonely. Lonely individuals even tend to become more socially isolated over time. While prevalence rates of social isolation increase with advancing age, only a minority of older people suffer from severe loneliness, however. Hence, loneliness is not necessarily a consequence of growing old, but rather, depends on specific risk factors (e.g., social needs, social expectations, resources, and competencies). Interventions therefore should be focused on these risk factors (unfulfilled social needs, unmet social perceptions, and lack of resources and competencies).

Social markers in language and speech are cues conveyed through verbal and nonverbal means that serve to identify individuals to the groups to which they belong. Social markers can be linguistic, paralinguistic, or extralinguistic in form, and can range from intentional and purposive (e.g., language selection or dialect accentuation) to unintentional and uncontrollable (e.g., vocal features that mark age or sex). They help to provide context for social organization. Extralinguistic cues are those that may be conveyed through gesture and physical appearance (i.e., skin color). However, social markers in language and speech focus on the paralinguistic (i.e., vocal cues such as pitch and tone) and linguistic cues (i.e., language choice, language style, accent, dialect, code-switching, and multilingualism) that mark social categories. Relevant social categories that are made distinctive through language and speech markers include age, sex and gender, social class, ethnicity, and many others. Scholars across disciplines of psychology, social psychology, linguistics, and communication have approached the study of social markers from different perspectives, resulting in theoretical (e.g., communication accommodation theory, ethnolinguistic vitality theory, linguistic intergroup bias) and methodological (e.g., matched-guise technique and ethnography of communication) advancements.

Social participation is a key element of a healthy later life; and from a life course perspective, social participation declines in later life, due to separation from employment and educational institutions, loss of partners and friends, and restrictions due to functional limitations. Thus, maintaining and increasing participation has gained attention from researchers, program administrators, and policy developers. The term “social participation” means activities that involve social exchange and choice, and volunteering is consistently included. Personal, behavioral, health and social services, economics, and social and physical environmental factors have been associated with social participation and volunteering. Higher levels of human capital, social capital, and cultural capital have been associated with higher levels of participation; and the built and social environment can facilitate engagement. Studies demonstrate the positive effects of social participation and volunteering on physical, cognitive, and psychological health of older adults. Role theory and concepts of coping as well as cognitive enrichment have been used to explain these positive outcomes.
Volunteering, as a form of social participation, has received much academic attention in the last decade for a few reasons because, more than other social activities, it is altruistic. This feature may increase the health-producing benefits of engagement as well as create good for the community. It is often referred to as creating a “win-win” for the individual and for society.
Individual, group, and community interventions have been developed to increase social participation. However, evidence supporting effectiveness is limited and programs are underutilized. Future directions include wider implementation of interventions and more attention to the role of environment in increasing social participation, the use of technology in social participation, and increased understanding of the pathways through with social participation and volunteering improve well-being in later life.

Language is a social behavior, and a key aspect of social interaction. Language is ubiquitous and usually occurs with other human behaviors across diverse contexts. Thus, it is difficult to study it in isolation. This difficulty may be why most social psychologists tend to neglect language. Language use, though, has implications for many social psychological processes, and given its role in daily social life, it is important to understand its social underpinnings. The 50+ year history of the field of language and social psychology highlights the relationship between language and communication, and also foregrounds the differences between the social-psychological and communication approaches. One central issue is bilingualism and the relationship among language, identity, and culture. Another is methodology, where social psychologists have tended to choose experimental and survey strategies to look at language (not always to the best advantage). This century has seen the development of new technologies that allow us to look at language at large scale and in rich detail, and which have the potential to transform this research. In part as a consequence, there are now many new topics emerging in language and social psychology, which help to set a new agenda for future research.

Over the entire life span, social relationships are essential ingredients of human life. Social relationships describe regular interactions with other people over a certain period and generally include a mental representation of the relationship and the relationship partner. Social relationships cover diverse types, such as those with family members, romantic partners, friends, colleagues, as well as with other unrelated people. In general, most of these relationships change in number, contact frequency, and relationship quality during adulthood and old age. For example, both the number of and contact with friends and other unrelated people generally decrease with advancing age, whereas the number of and contact with family members remain rather stable. Relatively little is known about longitudinal changes in the quality of relationships, apart from romantic relationships, because few longitudinal studies have tracked specific relationships. Some explanatory factors, which are discussed in the literature, are (a) motivational changes, (b) reduced time due to work and family demands during adulthood, and (c) resource constraints in older age. Future work on social relationships would benefit from increasingly applying dyadic and network approaches to include the perspective of relationship partners as well as from examining online and offline contact in social relationships, which has already proved important among younger adults.

The sociocultural aspects of sport injury and recovery include the broad landscape of social beliefs, climates, processes, cultures, institutions, and societies that surround the full chronological spectrum of sport injury outcomes, ranging from risk through to rehabilitation and retirement. A social ecological view of research on this topic demonstrates that sociocultural influences affect sport injury outcomes via interrelated sport systems extending from the intrasystem (i.e., within sports persons) through the microsystem (i.e., sport relationships), mesosystem (i.e., sport organizations), exosystem (i.e., sport governing bodies), and macrosystem (i.e., sport cultures). Affected sport injury outcomes include sport injury risks and responses during rehabilitation, return to play, and retirement from sport.
Some specific examples of sociocultural themes evident in research literature include personal conformity to the cultural expectation to play hurt, social conventions of behavior when sport injuries occur, institutional character or ethics when making return to play decisions, guidelines for the care of athletes prescribed by sport governing bodies, and the economic costs to society for sport injuries. Many elements of sport injury are affected by these sociocultural influences, such as the risk of injuries, rehabilitation processes, and career terminations. Continuing debates and discussions include advocacy for sport rule changes, bans on dangerous sports, institutional responsibility, and global sport safety efforts. These form the basis for recommendations about sociocultural interventions designed to reduce sport injury risks and optimize effective injury recoveries through social and cultural best practices.
