Personnel selection is one of the most critical processes in the study of human work behavior because it determines the efficacy of many other issues of human resource management (e.g., training, productivity, and culture). From this perspective, personnel selection is a process of decision-making, and its main objective is to predict the future performance of potential employees. In order to achieve this objective, personnel selection identifies the individual requirements of job performance and uses a variety of assessment procedures, including cognitive ability tests, personality inventories, interviews, job knowledge tests, situational judgment tests, job experience, work sample tests, assessment centers, biodata, and reference checks. Using the best combination of predictors, currently, scientific personnel selection is capable of predicting and explaining over 60% of job performance variance based on individual differences.

Healthy aging is associated with changes in sensory, motor, cognitive, and emotional functions. Such changes depend on various factors. In particular, physical activity not only improves physical and motor but also cognitive and emotional functions. Observational (i.e., associations) and cross-sectional studies generally show a positive effect of regular physical exercise on cognition in older adults. Most longitudinal randomized controlled intervention studies also show positive effects, but the results are inconsistent due to large heterogeneity of methodological setups. Positive changes accompanying physical activity mainly impact executive functions, memory functions, and processing speed. Several factors influence the impact of physical activity on cognition, mainly the type and format of the activity. Strength training and aerobic training yield comparable but also differential benefits, and all should be used in physical activities. Also, a combination of physical activity with cognitive activity appears to enhance its effect on cognition in older age. Hence, such combined training approaches are preferable to homogeneous trainings. Studies of brain physiology changes due to physical activity show general as well as specific effects on certain brain structures and functions, particularly in the frontal cortex and the hippocampus, which are those areas most affected by advanced age. Physical activity also appears to improve cognition in patients with mild cognitive dysfunction and dementia and often ameliorates the disease symptoms. This makes physical training an important intervention for those groups of older people.
Apart from cognition, physical activity leads to improvement of emotional functions. Exercise can lead to improvement of psychological well-being in older adults. Most importantly, exercise appears to reduce symptoms of depression in seniors. In future intervention studies it should be clarified who profits most from physical activity. Further, the conditions that influence the cognitive and emotional benefits older people derive from physical activity should be investigated in more detail. Finally, measures of brain activity that can be easily applied should be included as far as possible.

The physical, psychological, and economic benefits of regular moderate-to-vigorous-intensity physical activity are well substantiated. Unfortunately, few people in developed countries engage in enough physical activity to reap these benefits. Thus, a strong theoretical understanding of what factors are associated with physical activity is warranted in order to create effective and targeted interventions. Social/ecological approaches to understanding physical activity demonstrate the breadth of correlates that encompass intra-individual, inter-individual, environmental, and policy-related variables in physical activity performance. One longstanding intrapersonal correlate of interest is the relationship between personality traits—enduring individual-level differences in tendencies to show consistent patterns of thoughts, feelings, and actions—and physical activity.
Personality trait theories are broad in focus and differ in terms of proposed etiology, yet much of the recent research in physical activity has been with super traits in the five-factor model: neuroticism, extraversion, openness, agreeableness, and conscientiousness. Meta-analytic reviews suggest that conscientiousness and extraversion are positively associated with physical activity with some mixed evidence for a small negative relationship with neuroticism. The effect appears to be most pronounced with vigorous physical activities and less so with lower-intensity lifestyle activities and shows mixed evidence for whether proximal social cognitive variables (intention, self-efficacy) can mediate this relationship. More specific sub-traits show that facets of extraversion (excitement-seeking, activity) or conscientiousness (self-discipline, industriousness/ambition) have larger and more specific associations with particular types of physical activity or moderate key processes like the intention-behavior gap. Furthermore, personality appears to be linked to higher-intensity and adventure activities more than lower-intensity leisure physical activities. Contemporary longitudinal assessments of the bi-directionality of personality and physical activity have begun to advance our understanding of interconnectedness. Interventions that target personality traits to improve physical activity have been relatively understudied but hold some promise when used in tandem with larger theoretical approaches and behavioral change strategies.

Research indicates that both acute and chronic physical activity improve sleep. Effects on sleep include prolongation of total sleep time, slow wave sleep increase, rapid eye movement sleep decrease, wake after sleep onset reduction, and shortened sleep latency. However, detailed biological mechanisms of these effects have not been well elucidated.
Past studies strongly suggest that the sleep-promoting effect of exercise could be multifactorial. Increase of slow wave sleep, which has been repeatedly reported, strongly suggests physical activity effects on central nervous system function. Physical activity also elevates body temperature, alters glucose, and impacts other metabolic regulations. Habitual exercise also alters autonomic nervous system predominance measured by heart rate variability.

Cardiovascular disease has been estimated to be responsible for over 30% of deaths worldwide. The traditional cardiovascular risk factors of smoking, obesity, diabetes, physical inactivity, and family history predict about 50% of the variance of new cardiovascular disease cases; therefore, a number of other risk factors must contribute to cardiovascular disease development. One such factor is psychological stress, which has been identified as playing a role in the development of cardiovascular disease. The major research strategy for assessing the impact of psychological stress on cardiovascular disease development is to measure cardiovascular reactivity to laboratory mental stressors. Exaggerated mental stress-induced cardiovascular reactivity and slow stressor recovery have been associated with the development of cardiovascular disease.
In contrast to exposure to psychological stress, there is strong evidence that participation in aerobic exercise leads to a reduction in cardiovascular disease. Participation in regular aerobic exercise generally reduces the cardiovascular response to acute exercise; therefore, researchers have hypothesized that the ability of aerobic exercise to enhance cardiovascular health works partly by modifying the cardiovascular reactivity response to mental stressors. There is mixed evidence to suggest that chronic aerobic exercise decreases or increases cardiovascular reactivity to mental challenge in normotensive, healthy individuals. A decrease in reactivity, however, has been found in those studies that have examined individuals at risk of disease or diseased adults. The optimal volume and intensity of aerobic exercise that brings about maximum decreases in cardiovascular reactivity has yet to be determined. The impact of other forms of exercise on reactivity such as resistance exercise and interval sprinting exercise is starting to be assessed. The challenge for researchers in this area is to identify the mode of exercise that takes the least amount of time but brings about the greatest reduction of levels of stress-induced cardiovascular disease.

A historically popular research topic in exercise psychology has been the examination of the exercise-anxiety relationship, with an ever-growing literature exploring the link between exercise and anxiety. In addition to its potential for preventing anxiety and anxiety disorders, an increasing number of studies have examined the utility of physical activity and exercise interventions for the treatment of elevated anxiety and clinical anxiety disorders. A National Institute of Mental Health “state-of-the-art workshop” in 1984 was the first significant call put forth that understanding the anxiety-reducing potential of exercise was important and required further investigation. Since the publication of the evidence that came out of that NIMH workshop in Morgan and Goldston’s 1987 book, “Exercise and Mental Health,” a great deal more has been learned yet key aspects of the relationship between exercise and anxiety remain unknown. There is a great deal of work that remains to make good on the “potential efficacy of exercise.”

There is substantial interest in identifying the behavioral means by which to improve cognitive performance. Recent research and commercial ventures have focused on cognitive training interventions, but evidence suggests that the effects of these programs are small and task-specific. Researchers have also shown interest in exploring the potential benefits of physical activity for cognitive performance. Because the effects of physical activity have been found to be small to moderate and to be more global in nature, interest in physical activity has been growing over the past several decades. Evidence regarding the efficacy of physical activity is provided through cross-sectional studies, longitudinal prospective studies, and randomized controlled trials. When reviewed meta-analytically, small-to-moderate beneficial effects are reported for children, adults, older adults, and cognitively impaired older adults, and these effects are evident for a wide range of cognitive domains, including executive function, memory, and information processing. Researchers are currently focused on identifying the mechanisms of these effects. Most of this research has been conducted using animal models, but there is a growing body of literature with humans. From this evidence, there is support for the role of changes in cerebral structure, hippocampal perfusion, and growth factors in explaining the observed benefits. Thus far, however, the literature is quite sparse, and future research is needed to clarify our understanding of the mechanisms that provide the causal link between physical activity and cognitive performance. Research is also focused on understanding how to increase the benefits by potentially combining cognitive training with physical activity and by identifying the genetic moderators of the effects. These lines of work are designed to elucidate ways of increasing the magnitude of the benefits that can be obtained. At this point in time, the evidence with respect to the potential of physical activity for benefiting cognitive performance is quite promising, but it is critical that funding agencies commit their support to the continued exploration necessary to allow us to ultimately be able to prescribe physical activity to specific individuals with the express purpose of improving cognition.

Depression is a leading cause of global burden affecting people across all ages, genders, and socioeconomic groups. Antidepressants are the cornerstone of treatment, yet treatment response is often inadequate. While some psychological interventions such as cognitive behavioral therapy can also help alleviate depressive symptoms, alternative and complimentary treatment options are required. In particular, therapeutic interventions that also address the greatly increased levels of obesity and cardiovascular disease among people with depression may offer added value. With the rising burden of premature mortality due to cardiovascular disease in people with depression and promising evidence base for physical activity to improve depressive symptoms, it is important to review the role, benefits, and underlying neurobiological responses of exercise among people with depression.
There has been a growing body of evidence to suggest that higher levels of physical activity reduce a person’s risk of incident depression. It appears that lower levels of cardiorespiratory fitness increase an individual risk of depression, suggesting that physical activity and physical fitness have a key role in the prevention of depression. Moreover, exercise can improve depressive symptoms in those with subthreshold depressive symptoms and major depressive disorder. Despite the effectiveness of exercise, the optimal dose and frequency are yet to be fully elucidated. Nonetheless, exercise appears to be well accepted by people with depression, with relatively low levels of dropout from interventions, particularly when supervised by qualified professionals with expertise in exercise prescription. Various barriers to engaging in exercise exist and motivational strategies are essential to initiate and maintain exercise. A number of hypotheses have been postulated to determine the antidepressant effect of exercise; however, most are based on animal models or models elucidated from people without depression. Therefore, future representative research is required to elucidate the neurobiological antidepressant response from exercise in people with depression. Physical activity interventions targeting fitness should be a central part of the prevention and management of depression. In particular, physical activity interventions offer a viable option to prevent and address cardiometabolic abnormalities and cardiovascular disease, which account for a significant amount of premature deaths in this population and are not addressed by standard pharmacological and psychological therapies.

Health-related quality of life (HRQL) is a multidimensional subcomponent of quality of life involving subjective appraisal of various dimensions of one’s life that can be affected by health or health-related interventions. There is considerable evidence demonstrating that exercise consistently results in meaningful improvements in an array of HRQL outcomes. Advances in the conceptualization of HRQL and recent evidence identifying select moderators and mediators of the effects of upon HRQL outcomes have important implications for the design and delivery of exercise interventions. Taken collectively, contemporary findings support the utility of adopting a hierarchical, bottom-up approach to the investigation of the effects of exercise upon HRQL.

Along with the social, economic, care-related, organizational, and technological context, the physical and infrastructural environment indoors and out of the home has gained attention in behavioral aging research as well as in gerontology as a whole since the 1960s. There is, however, an ongoing trend to downplay physical-infrastructural environments in behavioral aging research at the conceptual and empirical level. Therefore, substance is provided to support the usefulness of ecology and aging perspectives for the psychology of aging by mainly addressing North American and European research in the area.
Globalization has become an influential force in the construction of older age, notably in the framing of social and economic policies designed to manage and regulate demographic change. National institutions such as the welfare state provided a distinctive shape and associated meanings to the final phase of the life course in Western societies during the 20th century. This process was disrupted from the 1990s onward, with a combination of more intense processes of globalization and accelerated international migration. A transformed cultural context is influencing a move from a linear life course toward one in which events influencing later life are scattered across a broad spectrum of time, space, and chronological age.
Globalization will undoubtedly be a major factor in shaping the lives of older people through the 21st century. The types of changes it will bring are easy to predict in some respects, much less so in others. Older people will certainly be living in a culturally and socially diverse world, increasingly aware not only of the aging of their own society but also the impact of growing old on communities across the globe. An additional change will be the influence of supranational bodies in determining policies in areas such as Social Security and health and social care, these creating the framework for resources for support for old age. Globalization—as one constituent of the “risk society”—may also generate new forms of insecurity for individuals, of which anxieties and fears about aging could represent a significant dimension.

Although psychotherapy is on balance effective for a broad array of psychological problems, a relatively small but steadily accumulating body of evidence suggests that at least some psychological interventions are harmful. Until recently, however, relatively little research attention has been paid to the identification of harmful psychological treatments. Although it has long been recognized that a nontrivial minority of people become worse following therapy, this finding does not necessarily mean that they have become worse because of therapy. Nevertheless, recent research has homed in on a small subset of interventions that may produce psychological harm, physical harm, or both. In addition, there is growing interest in pinpointing potential mechanisms of deterioration effects in psychotherapy, as well as in distinguishing harmful therapies from harmful therapists.

Prejudice is an attitude toward a social group and its members that can be expressed as either a negative or positive (e.g., paternalistic) evaluation and creates or maintains hierarchical status relations between groups. The origins of prejudice include individual differences in personality and ideological preferences, socialization experiences relating to exposure to different social norms, and the functional ways that groups relate to one another. Prejudice can be measured directly through self-report measures or indirectly through patterns of behavior or with techniques such as response latency methods. Moreover, implicit prejudice, which is automatically activated, can be distinguished from explicit prejudice, an attitude people know that they hold and may be able to control. Both types of prejudice predict discrimination—the differential treatment of a group or its members—but the strength of these relationships varies as a function of a variety of contextual factors (e.g., social norms). Because of the wide range of forces that shape prejudice and the functional nature of bias, prejudice can be difficult to change. Among the more robust ways to reduce prejudice are strategies that promote frequent, positive contact with members of another group; encourage people to categorize others in ways that emphasize shared group identities; or alter automatic associations underlying implicit bias. The study of prejudice continues to be an important and actively researched topic in social psychology, with contemporary approaches increasingly considering a broader range of micro- (e.g., genetics) and macro-level (e.g., culture) forces that shape the nature of prejudice and its influence on discriminatory behavior.

Although the specific prevalence rates may vary, eating disorders (ED) affect male and female athletes regardless of sport type and competitive level. Generally, rates of subclinical disorders are much higher than clinical ones, with the most frequent clinical classification being Eating Disorders Not Otherwise Specified. Further, EDs occur not only among active athletes, but are also found in samples of retired athletes as well. Existing research on the prevalence of EDs in athletes, however, has been limited due to its reliance on out-of-date diagnostic criteria, sometimes small samples, and a focus on point prevalence to the exclusion of examining how rates might change over time. Central to prevalence research and clinical assessments is the ability to accurately assess EDs in athletes. Although structured clinical interviews represent the most valid approach, they are time consuming and not often used in determining prevalence. Researchers have relied on self-report measures instead. Such measures include those developed initially in nonathletes, but used to study athletes (e.g., Questionnaire for Eating Disorder Diagnosis; Mintz, O’Halloran, Mulholland, & Schneider, 1997), and those specifically for athletes (e.g., Athletic Milieu Direct Questionnaire; Nagel, Black, Leverenz, & Coster, 2000). Most of these measures, though having adequate psychometric properties, are based on diagnostic criteria that are no longer in use, so additional research that employs prevalence measures that reflect DSM-5 criteria is needed with athletes. Most ED research in sport has used samples of active athletes; few studies have considered how the transition out of sport might affect athletes’ perceptions of their bodies, their relationship to food, and their approaches to exercise and being physically active. Retirement from sport generally is considered to be a developmental stressor and thus may exacerbate ED symptoms and body image concerns in some athletes. Yet, for other athletes, retirement may represent a positive transition in which they emerge from a sport culture, focused on weight and appearance, to reclaim themselves and their bodies. Initial qualitative findings appear to support each hypothesis in part, though longitudinal quantitative studies that track athletes from active competition through retirement are needed to understand the changes athletes experience in relation to their bodies, food, and exercise, and when such changes are most likely to occur.

Progressive neurological disorders are incurable disorders with gradual deterioration and impacting patients for life. Two common progressive neurological disorders found in late life are Parkinson’s disease (PD) and motor neuron disease (MND). Psychological complications such as depression and anxiety are prevalent in people living with PD and MND, yet they are underdiagnosed and poorly treated.
PD is classified a Movement Disorder and predominantly characterized by motor symptoms such as tremor, bradykinesia, gait problems and postural instability; however, neuropsychiatric complications such as anxiety and depression are common and contribute poorly to quality of life, even more so than motor disability. The average prevalence of depression in PD suggest 35% and anxiety in PD reports 31%. Depression and anxiety often coexist. Symptoms of depression and anxiety overlap with symptoms of PD, making it difficult to recognize. In PD, daily fluctuations in anxiety and mood disturbances are observed with clear synchronized relationships to wearing off of PD medication in some individuals. Such unique characteristics must be addressed when treating PD depression and anxiety. There is an increase in the evidence base for psychotherapeutic approaches such as cognitive behavior therapy to treat depression and anxiety in PD.
Motor neuron disease (MND) is classified a neuromuscular disease and is characterized by progressive degeneration of upper and lower motor neurons is the primary characteristic of MND. The most common form of MND is Amyotrophic lateral sclerosis (ALS) and the terms ALS and MND are simultaneously used in the literature. Given the short life expectancy (average 4 years), rapid deterioration, paralysis, nonmotor dysfunctions, and resulting incapacity, psychological factors clearly play a major role in MND. Depression and suicide are common psychological concerns in persons with MND. While there is an ALS-specific instrument to assess depression, evaluation of anxiety is poorly studied; although emerging studies suggesting that anxiety is highly prevalent in MND. Unfortunately, there is no substantial evidence-base for the treatment of anxiety and depression in MND.
Caregivers play a major role in the management of progressive neurological diseases. Therefore, evaluating caregiver burden and caregiver psychological health are essential to improve quality of care provided to the patient, as well as to improve quality of life for carers. In progressive neurological diseases, caregiving is often provided by family members and spouses, with professional care at advanced disease. Psychological interventions for PD carers addressing unique characteristics of PD and care needs is required. Heterogeneous clinical features, rapid functional decline, and short trajectory of MND suggest a multidisciplinary framework of carer services including psychological interventions to mitigate MND. A Supportive Care Needs Framework has been recently proposed encompassing practical, informational, social, psychological, physical, emotional, and spiritual needs of both MND patients and carers.

Tasks that involve remembering to carry out future intentions (such as remembering to attend an appointment), and the cognitive processes that enable the completion of such tasks (such as planning), are referred to as prospective memory (PM). PM is important for promoting quality of life across many domains. For instance, failures in remembering to meet social commitments are linked to social isolation, whereas failures in remembering to fulfill occupational goals are linked to poorer vocational outcomes. Declines in PM functioning are of particular concern for older adults because of the strong links between PM and functional capacity. The relationship between age and PM appears to be complex, dependent on many factors. While some aspects of PM appear to hold up relatively well in late adulthood, others appear to show consistent age-related decline. Variability in age differences appears to partially reflect the fact that there are diverse types of PM tasks, which impose demands on a range of cognitive processes that are differentially affected by aging. Specifically, the level and type of environmental support associated with different PM task types appears to be a meaningful determinant of age-related effects. Given the worldwide changing age demographics, the interest in age-related effects on PM will likely intensify, and a primary focus will be how to optimize and maintain PM capacity for this population. This is already reflected in the increasing research on interventions focused on enhancing PM capacity in late adulthood, and points to important future directions in this area of study.

Psychodynamic psychotherapies (PDP) is an umbrella term for a variety of therapeutic modalities that have evolved out of the psychoanalytic/psychodynamic tradition, each theorizing a trajectory of human development that includes an etiology of and treatment for psychopathology. PDPs have in common the belief that people have an unconscious mind that influences thoughts and behaviors outside of the individual’s awareness. These processes operate from birth till death and are responsible for adaptive and maladaptive functioning at the level of interpersonal relationships and daily living.
The psychodynamic therapist creates a case formulation for the individual seeking treatment, which incorporates a formal diagnosis with an understanding of the underlying dynamic factors contributing to the individual’s suffering. From this case formulation a treatment plan is created specific to the individual. During treatment, the therapist develops a strong working alliance while utilizing psychodynamic-specific techniques targeted at bringing insight into these unconscious thoughts and behaviors. Greater self-understanding enables greater choice ability and flexibility in functioning.
In contrast to prevalent views, empirical research has found support for the efficacy of PDP in the treatment of mental disorders, including but not limited to: depression, anxiety disorders, somatic disorders, and personality disorders. In general, PDP was found more effective than control conditions and not different from active treatments. PDP effects have been shown to remain stable post treatment.

The practice of athletic training involves both physical and psychological strategies when leading patients through the injury recovery process. Research on the psychology of injury offers theoretical foundations that guide the application of strategies to assist the patient with stressors that emerge during rehabilitation. This article applies theory to athletic training practice during injury recovery by examining the stressors that patients experience across the phases of rehabilitation. Addressing both physical and psychological aspects of injury recovery is expected by patients and provides a holistic care model for healthcare practitioners.

Worldwide, tobacco use is a leading cause of morbidity and mortality. However, the health effects of smoking are reversible, making smoking cessation an important target for public health policy. Tobacco control is a field of public health science dedicated to reducing tobacco use and, thereby, to reducing cigarette-related morbidity and mortality. For tobacco control to be effective, it is necessary for policy makers to understand the personal and interpersonal factors which encourage people to smoke, factors which motivate smokers to quit (e.g., health, social pressure, cost), and the personal and population-level methods that are most effective at encouraging and prolonging attempts to quit. Research has identified that social norms, mental health, and individual personality factors are most associated with smoking uptake, so interventions which reduce social smoking (e.g., smoking bans, plain packaging) would be most effective at preventing uptake. Conversely, the use of cigarettes is maintained by nicotine addiction and attempts to quit are often motivated by health concerns, social pressure and the cost of tobacco products. As such, interventions that address physiological and behavioral addiction inherent in tobacco product use (e.g., nicotine replacement therapy combined with counselling), that create social pressure to stop (e.g., mass media campaigns), or that increase the cost of tobacco products are most likely to be effective at encouraging attempts to quit.

The assessment of older adults is quite challenging in light of the many age-related physiological and metabolic changes, increased number of chronic diseases with potential psychiatric manifestations, the associated medications and their side effects, and the age-related changes in the presentation of common mental health problems and disorders. A biopsychosocial approach to assessment is particularly important for older adults due to the substantial interplay of biological, psychological, and social factors that collectively produce the clinical presentation faced by clinicians. An appreciation of age-related and non-normative changes in cognitive skills and sensory processes is particularly important both for planning the assessment process and the interpretation of findings. The assessment of older adults is unfortunately plagued by a paucity of age-appropriate assessment instruments, as most instruments have been developed with young adults. This paucity of age-appropriate assessment instruments is an impediment to reliable and valid assessment. Notwithstanding that caveat, comprehensive and valid assessment of older adults can be accomplished through an understanding of the interaction of age-related factors that influence the experience and presentation of psychiatric disorders, and an appreciation of the strengths and weaknesses of the assessment instruments that are used to achieve valid and reliable assessments.
