Retirement, defined as an individual’s exit from the workforce, is usually accompanied by a behavioral withdrawal from work. While retirement was seen as a crisis in the past, it now stands as an opportunity for individuals to engage in different types of work (e.g., bridge employment), and to dedicate more time in their community with friends and family. Cross-national studies have been conducted to clarify the impact of preparedness on the temporal process of retirement: decisions, transition, and adjustment to retirement. Nevertheless, societies are constantly changing and future research, with the frameworks discussed in this chapter in mind, can continue investigating the concepts of retirement to help individuals prepare better.
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.

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.

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.

Children with specific language impairment (SLI) have a significant deficit in their ability to acquire language that cannot be attributed to intellectual disability, neurological damage, hearing loss, or a diagnosis of autism. These deficits can be long-standing, and adversely affect other aspects of the affected individual’s life. There seems to be a genetic component to SLI, but the disorder is not likely to be traced to a single gene. The problem appears to be universal, but symptoms vary depending on the language being learned. Current attempts to account for SLI have increased our understanding of the most salient symptoms of the disorder, but a full understanding of SLI is not yet within reach.

The comprehension of spoken language is a complex skill that, in any language, requires the listener to map the acoustic input onto the meaningful units of speech (phonemes, syllables, words). At the sentence level, the listener must detect the syntactic structure of the utterance in order to determine the semantic relationships among the spoken words. This culminates in comprehension at the discourse and narrative level. Each higher level of analysis is thus dependent on successful processing at the prior level, beginning with perception at the phoneme and word levels.
Unlike reading, where one can use eye movements to control the rate of input, speech is a transient signal that moves past the ears at an average rate of 140 to 180 words per minute. Whatever processing cannot be completed online, as the speech is arriving, must be accomplished on a fading trace of the speech input in memory. Although seemingly automatic in young adults, comprehension of rapid speech places a heavy burden for older adults, who often exhibit a combination of reduced working memory resources and slower processing rates, as observed across a number of perceptual and cognitive domains. An additional challenge arises from reduced hearing acuity that often occurs in adult aging. A major concern is that, even with only mild hearing loss, the listening effort required for success at the perceptual level may draw resources that would ordinarily be available for encoding what has been heard in memory, or comprehension of syntactically complex speech. On the positive side, older adults have compensatory support from preserved linguistic knowledge, including the procedural rules for its use. Our understanding of speech perception in adult aging thus rests on our understanding of such sensory-cognitive interactions.

Stigma is a complex process that results from the interaction of stereotypes, prejudice, and discrimination. When applied to health conditions (e.g., mental illness, HIV/AIDS, diabetes, obesity), stigma can contribute to a lack of recovery and resources as well as devaluation of the self. People with stigmatized health conditions may be too embarrassed to seek treatment and others may not provide them with equal opportunities. This often results in discrimination in employment, housing, and health care settings. Strategies have been proposed to prompt stigma change with strategic contact between those with the health condition and everyone else likely to have the best effects.

Strength training sessions are developed and overseen by strength and conditioning coaches, whose primary responsibilities are to maximize individuals’ athletic performance and minimize their injury risk. As the majority of education and certification for being a strength and conditioning coach focuses on physiology and physiological adaptations, biomechanics, and related scientific areas of study, there has been less emphasis on coaching behaviors, motivational techniques, pedagogical approaches, or psychological skills. These are important areas because to accomplish both long-term and short-term training goals, strength and conditioning coaches should use and train their athletes in the use of these techniques.
Motivation of training session participants is essential to being an effective strength and conditioning coach. Coaches motivate their athletes through their behaviors, design and organization of the training sessions, teaching techniques, role modeling, relationships with the athletes, and the psychological skills they incorporate within and outside of the training sessions. Coaches also often teach athletes about psychological skills not to motivate the athlete but to assist the athlete in their performance, mental health, or general well-being. Some of these psychological skills are so ingrained in the strength and conditioning discipline that coaches do not recognize or categorize them as psychological skills. Because of the relationship built between strength coach and athlete, the strength and conditioning coach often provides informal knowledge of advice on topics regarding general life lessons or skills that can actually be categorized under psychological skills. However, the lack of formal education and training in sport psychology techniques also means that strength and conditioning coaches do not take full advantage of many behaviors, motivational techniques, and other psychological skills. These areas remain an area for further professional development and research within the strength and conditioning field.

There are close parallels between surgical performance and performance in competitive sports. For example, both require significant gross and fine motor ability and effective concentration skills, and both are routinely performed in dynamic environments under significant time constraints. Given such parallels, it is not surprising that there has been an upsurge of research interest in the psychological processes that underlie expertise in surgical performance. Of these processes, perhaps the most frequently studied in recent years is that of motor imagery (MI; also known as “mental practice” or MP), the cognitive simulation skill that enables us to “see” and “feel” actions in our imagination without engaging in the physical movements involved. Current research interest in the role of motor (or “feeling oriented”) imagery in surgical performance is attributable to a combination of theoretical and practical factors. Specifically, at a theoretical level, hundreds of experimental studies in psychology have demonstrated the efficacy of MI/MP in improving skill learning and skilled performance in a variety of fields such as sport and music. The most widely accepted explanation of these effects comes from simulation theory, which postulates that executed and imagined actions share some common neural circuits and cognitive mechanisms. Put simply, imagining a skill activates some of the brain areas that are involved in its actual execution. Accordingly, systematic engagement in MI/MP appears to “prime” the brain for optimal skilled performance. Turning to the practical level, as surgical instruction has moved largely from an apprenticeship model (the so-called, “see one, do one, teach one” approach) to a model based on simulation technology (e.g., the use of virtual reality equipment), there has been a steady growth of interest in the potential of cognitive training techniques (e.g., MI/MP) to improve surgical skills and performance. Although these cognitive training techniques suffer both from certain conceptual confusion (e.g., with regard to the clarity of key terms) and inadequate empirical validation, they offer considerable promise in the quest for a cost-effective supplementary training tool in surgical education. Against this background, it is important for researchers and practitioners alike to evaluate progress in understanding the cognitive psychological factors (such as motor imagery) that underlie surgical skill learning and performance.
