Human visual development is a complex dynamic psychological/neurobiological process, being part of the developing systems for cognition, action, and attention. This article reviews current knowledge and methods of study of human visual development in infancy and childhood, in relation to typical early visual brain development, and how it can change in developmental disorders, both acquired (e.g., related to at-risk births) and genetic disorders. The newborn infant starts life with a functioning subcortical visual system which controls newborn orienting to nearby high contrast objects and faces. Although visual cortex may be active from birth, its characteristic stimulus selectivity and control of visual responses is generally seen to emerge around six to twelve weeks after birth. By age six months the infant has adequate acuity and contrast sensitivity in nearby space, and operating cortical mechanisms for discriminating colors, shapes, faces, movement, stereo depth, and distance of objects, as well as the ability to focus and shift attention between objects of interest. This may include both feedforward and feedback pathways between cortical areas and between cortical and subcortical areas. Two cortical streams start to develop and become interlinked, the dorsal stream underpinning motion, spatial perception and actions, and the ventral stream for recognition of objects and faces. The neural systems developing control and planning of actions include those for directed eye movements, reaching and grasping, and the beginnings of locomotion, with these action systems being integrated into the other developing subcortical and cortical visual networks by one year of age. Analysis of global static form (pattern) and global motion processing allows the development of dorsal and ventral streams to be monitored from infancy through childhood. The development of attention, visuomotor control and spatial cognition in the first years show aspects of function related to the developing dorsal stream, and their integration with the ventral stream.
The milestones of typical visual development can be used to characterize visual and visuo-cognitive disorders early in life, such as in infants with perinatal brain injuries and those born very prematurely. The concept of “dorsal stream vulnerability” is outlined. It was initially based on deficits in global motion sensitivity relative to static form sensitivity, but can be extended to the planning and execution of visuomotor actions and problems of attention, together with visuospatial and numerical cognition. These problems are found in the phenotype of children with both genetic developmental disorders (e.g., Williams syndrome, autism, fragile-X, and dyslexia), and in acquired developmental disorders related to very preterm birth, or in children with abnormal visual input such as congenital cataract, refractive errors, or amblyopia. However, there are subtle differences in the manifestation of these disorders which may also vary considerably across individuals. Development in these clinical conditions illustrates the early, but limited, plasticity of visual brain mechanisms, and provides a challenge for the future in designing successful intervention and treatment.

Lev Semyonovich Vygotsky (real name Lev Simkhovich Vygodsky; Orsha 1896–Moscow 1934) was a Russian psychologist who created cultural-historical theory, which proved influential in developmental psychology and other psychological disciplines. Vygotsky characterized his approach as “height psychology” (as opposed to “depth psychology”) and posited that the higher forms of mind should be the starting point for the study of human development. In his view it was essential to study psychological processes in their historical dynamics; these dynamics could be unraveled with the causal-genetic approach he developed, which involved the guided formation of mind in the course of its study or the experimental unfolding of ontogeny. Vygotsky claimed that the mechanisms of human development are not genetically determined and that we must find its source in culture and the social environment. Human development is mediated by cultural artifacts and sign systems, which are mastered in a dialogue with other people in spontaneous or guided interaction, which stimulates development by creating a zone of proximal development. The major means of the transformation of innate mind into higher mind is language, which enables us to preserve and transmit the experience of generations. In this process of cultural development the person develops a system of higher psychological functions that are social in origin, voluntary and mediated in nature, and form part of a systemic whole. The process of ontogeny goes through a series of stable periods and crises that correspond with specific conditions of the social situation of development and the developmental tasks. Age periods are completed with the development of neoformations, which do not just form results but are also prerequisites for further development. With the development of verbal thinking and the mastery of cultural means of behavior the person masters her/his innate mind and becomes a personality, whose main characteristic is freedom of behavior.

Wilhelm Wundt (1832–1920) is one of the most famous names in the history of psychology. After passing into oblivion for nearly 60 years, in recent decades he has been celebrated in general psychology textbooks as the founding father of scientific psychology. However, this traditional portrait is incomplete and can lead to misunderstandings, as his psychological program is primarily understood in terms of experimental psychology.
In order to complete this traditional picture, two aspects of his work must be emphasized and clarified: the role of Völkerpsychologie as the counterpart of experimental or individual psychology, and the interaction between his psychological program and his philosophical project. The ultimate meaning of Wundt’s conception of scientific psychology cannot be understood in isolation from his broader philosophical goals. Reading Wundt from the point of view of such interaction offers a deeper understanding of his work.
In the literature of mainstream scientific psychology, German scholar William Stern has been known primarily (if at all) as the inventor of the intelligence quotient (IQ). In fact, however, Stern’s contributions to psychology were much greater and more consequential than this. In this all-inclusive article, I have sought to provide readers with a fuller appreciation for the breadth and depth of Stern’s work, and, in particular, for that comprehensive system of thought that he elaborated under the name “critical personalism.” Drawing frequently on translated quotations from Stern’s published works, and on his personal correspondence with the Freiburg philosopher Jonas Cohn, I have endeavored to show how Stern was much more than “the IQ guy.” During the first 20 years of his academic career, spent at the University of Breslau in what is now the Polish city of Wroclaw, Stern founded that sub-discipline of psychology that would be concentrated on the study of individual differences in various aspects of human psychological functioning. He also made major contributions to that sub-discipline referred to at the time as “child” psychology, and laid the foundations for a comprehensive system of thought that he would name “critical personalism.” After relocating to Hamburg in 1916, Stern continued his scholarly efforts in these domains, taught courses both in psychology and in philosophy at the university that opened its doors there in 1919, and played major administrative roles there in the institutional homes of both disciplines until forced to flee Nazi Germany in 1934. The present chapter highlights ways in which, over the course of his scholarly career, Stern boldly opposed certain trends within mainstream thinking that were ascendant during his time.

The concept of wisdom is ancient and deeply embedded in the cultural history of humanity. However, only since 1980s have psychologists begun to study it scientifically. Taking a culturally and philosophically informed perspective, this article integrates insights from the quantitative science of wisdom. Analysis of epistemological traditions and research on folk theories of wisdom suggest cultural similarities in the domain of cognition (e.g., wisdom as reasoning ability and knowledge). These similarities can be contrasted with cultural differences concerning folk-theoretical affective and prosocial themes of wisdom, as well as expression of various wisdom-related themes, rooted in distinct sociocultural and ecological environments. Empirical evidence indicates that wisdom is an individually and culturally malleable construct, consistent with an emerging constructionist account of wisdom and its development. Future research can benefit from integration of ecological and cultural-historical factors for the meaning of wisdom and its expression.

Study of the intersection of work with nonwork components of individuals’ lives has most often focused on roles within nuclear and extended families but is increasingly focused on nonwork domains beyond family, such as roles within friendships, communities, leisure activities, and the self. In line with the focus of most existing literature on the family-specific domain within nonwork lives, the nonwork domain will generally be referred to here as “family.” One popular conceptualization of linking mechanisms between work and family differentiates between work-family conflict or stress, which occurs when a work role and a nonwork role are not fully compatible and results in some type of physical or psychological strain. Alternatively, work-family enrichment occurs when participation in one role benefits life in the other role. Concepts similar to work-family enrichment include work-family positive spillover and work-family facilitation; all emphasize the ways in which one role can positively impact another role. Additionally, the popular concept of work-family balance highlights either a state of low conflict and high enrichment or the presence of effectiveness and satisfaction in both roles.
Broadly speaking, the links between work and family are bi-directional, such that the work domain can influence the family domain, the family domain can influence the work domain, and both can occur simultaneously. Work-family conflict and enrichment have been tied to important employee outcomes, including work (e.g., absenteeism), family (e.g., family satisfaction), and domain-unspecific outcomes (e.g., physical and psychological health), as well as to organizational outcomes (e.g., market performance). Working conditions contributing to work-family conflict and enrichment are frequently characteristic of lower wage jobs, such as low levels of control over work, high work demands, low levels of supervisor support, shift work, and temporary work that can lead to unpredictable schedules, high degrees of job insecurity, and increased health and safety hazards. Researchers are presented with unique challenges as the workplace continues to change, with more dual-earner couples, an increasingly aging workforce, and surges of technology that facilitates flexible work arrangements (e.g., telecommuting). Nonetheless, researchers and organizations work to explore relationships between work and family roles, develop policies related to work and family (i.e., national, state or local, and organizational), and build evidence-based interventions to improve organizations’ abilities to meet employees’ needs.
Working memory as a temporary buffer for cognitive processing is an essential part of the cognitive system. Its capacity and select aspects of its functioning are age sensitive, more so for spatial than verbal material. Assumed causes for this decline include a decline in cognitive resources (such as speed of processing), and/or a breakdown in basic control processes (resistance to interference, task coordination, memory updating, binding, and/or top-down control as inferred from neuroimaging data). Meta-analyses suggest that a decline in cognitive resources explains much more of the age-related variance in true working memory tasks than a breakdown in basic control processes, although the latter is highly implicated in tasks of passive storage. The age-related decline in working memory capacity has downstream effects on more complex aspects of cognition (episodic memory, spatial cognition, and reasoning ability). Working memory remains plastic in old age, and training in working memory and cognitive control processes yields near transfer effects, but little evidence for strong far transfer.

Work stress refers to the process of job stressors, or stimuli in the workplace, leading to strains, or negative responses or reactions. Organizational development refers to a process in which problems or opportunities in the work environment are identified, plans are made to remediate or capitalize on the stimuli, action is taken, and subsequently the results of the plans and actions are evaluated. When organizational development strategies are used to assess work stress in the workplace, the actions employed are various stress management interventions. Two key factors tying work stress and organizational development are the role of the person and the role of the environment. In order to cope with work-related stressors and manage strains, organizations must be able to identify and differentiate between factors in the environment that are potential sources of stressors and how individuals perceive those factors. Primary stress management interventions focus on preventing stressors from even presenting, such as by clearly articulating workers’ roles and providing necessary resources for employees to perform their job. Secondary stress management interventions focus on a person’s appraisal of job stressors as a threat or challenge, and the person’s ability to cope with the stressors (presuming sufficient internal resources, such as a sense of meaningfulness in life, or external resources, such as social support from a supervisor). When coping is not successful, strains may develop. Tertiary stress management interventions attempt to remediate strains, by addressing the consequence itself (e.g., diabetes management) and/or the source of the strain (e.g., reducing workload). The person and/or the organization may be the targets of the intervention. The ultimate goal of stress management interventions is to minimize problems in the work environment, intensify aspects of the work environment that create a sense of a quality work context, enable people to cope with stressors that might arise, and provide tools for employees and organizations to manage strains that might develop despite all best efforts to create a healthy workplace.

In the literature on prejudice and derogatory reactions, two prominent lines of research can be distinguished, one focusing on the expression and endorsement of (mostly) negative stereotypes and prejudice, and one zooming in on how defense of cultural worldviews can lead to derogatory reactions toward those who are different from ourselves. Research on both stereotypes/prejudice and cultural worldviews reveals how personal uncertainty can lead to the occurrence of derogatory reactions. In research on prejudice, the automaticity of stereotyping and prejudice has been the subject of debate. Some scholars argue for the inevitability of stereotyping, as these processes are assumed to be automatic and inevitable. By contrast, other scholars distinguish automatic stereotype activation from more controlled stereotype endorsement. Importantly, stereotype activation may be altered by stereotype-negation training reducing the expression of prejudice. In worldview defense research, it is shown how uncertainty-related motives and other worldview threats are related to the expression of derogatory reactions toward those who fall outside our scope of justice.
In contemporary society, people frequently have to deal with feelings of personal uncertainty, especially regarding future-oriented delayed outcomes. To cope with these feelings, people adhere to their cultural worldviews. These belief systems enable people to strive for long-term goals, but also make them more vulnerable to expressing prejudice and other derogatory reactions. A wealth of research shows that when people’s worldviews are threatened, they tend to react more rigidly and negatively toward others, especially toward those who belong to an outgroup. For example, if one believes that the world is inherently just (i.e. in studies looking at “just world beliefs”), interacting with innocent victims of crimes can threaten this worldview. In the face of this conflict, people sometimes respond in derogatory and prejudiced ways toward those victims in order to uphold their belief that the world is a just place where bad things can only happen to bad people. Importantly, alleviating feelings of personal uncertainty (either by affirming personal certainty or by refocusing attention toward other aspects of an unjust situation) can reduce derogatory reactions and instigate benevolent reactions focused on helping those who are less well off.
