Four‐Month‐Olds' Discrimination of Optic Flow Patterns Depicting Different Directions of Observer Motion

One of the most powerful sources of information about spatial relationships available to mobile organisms is the pattern of visual motion called optic flow. Despite its importance for spatial perception and for guiding locomotion, very little is known about how the ability to perceive one's direction of motion, or heading, from optic flow develops early in life. In this article, we report the results of 3 experiments that tested the abilities of 4‐month‐old infants to discriminate optic flow patterns simulating different directions of self‐motion. The combined results from 2 different experimental paradigms suggest that 4‐month‐olds discriminate optic flow patterns that simulate only large (> 32°) changes in the direction of the observer's motion through space. This suggests that prior to the onset of locomotion, there are limitations on infants' abilities to process patterns of optic flow related to self‐motion.     

Demands on Finite Cognitive Capacity Cause Infants' Perseverative Errors

This research unites traditionally disparate developmental domains—cognition and locomotion—to examine the classic cognitive issue of the development of inhibition in infancy. In 2 locomotor A‐not‐B tasks, 13‐month‐old walking infants inhibited a prepotent response under low task demands (walking on flat ground), but perseverated under increased task demands (descending a staircase). Despite elimination of factors previously associated with infant perseveration, infants still perseverated in the difficult stairs condition. Increasing cognitive load by manipulating task difficulty affected infants' ability to inhibit repeated responses that were no longer appropriate. Evidence supports a cognitive capacity account of infant perseveration, in which infants' performance depends on allocation of cognitive and attentional resources.     

Developmental Trajectories of Emotion Regulation Across Infancy: Do Age and the Social Partner Influence Temporal Patterns

The ability to effectively regulate emotions is a critical component of early socio‐emotional development. This longitudinal study examined the developmental trajectories of emotion regulation in a sample of 3‐, 5‐, and 7‐month‐olds during an interaction with mothers and fathers. Infants' negative affect and use of behavioral strategies, including distraction, self‐soothing, and high intensity motor behaviors were rated during the still‐face episode of the Still‐Face Paradigm. Longitudinal mixed‐effects models were tested to determine whether strategies were followed by an increase or decrease in negative affect. Results from mother‐infant and father‐infant dyads indicated that focusing attention away from the unresponsive parent and engaging in self‐soothing behaviors were associated with a subsequent decline in negative affect and the strength of these temporal associations were stable across infancy. In contrast, high‐intensity motor behaviors were followed by an increase in negative affect and this effect declined over time. No significant effects were found for the behavioral strategy of looking at the parent. Results underscore the importance of considering infant age and the social partner when studying the effectiveness of emotion regulatory strategies in early infancy.     

College Student Psychological Distress: Relationship to Self‐Esteem and Career Decision Self‐Efficacy Beliefs

College students experience a number of stressors, such as adjustment to a new environment, postgraduation planning, and the balancing of changing roles and responsibilities. These stressors may contribute to increased rates of psychological distress that have implications for their educational and career development. The purpose of this study was to extend understanding of the nature of the relationships among psychological distress, self‐esteem, and career decision self‐efficacy (CDSE) beliefs. Results from 292 undergraduate students demonstrated support for the proposed hypotheses. Psychological distress negatively related to self‐esteem and to CDSE. Self‐esteem was positively related to, yet distinct from, CDSE, and both self‐esteem and psychological distress contributed unique variance to the prediction of CDSE. Results highlight the importance of attending to student psychological distress in the provision of career counseling services. Future research that centralizes mental health is needed to better understand relationships among career development processes over time and within diverse student populations.     

Infant locomotion shapes proximity to adults during everyday play in the U.S.

Learning to walk expands infants’ access to the physical environment and prompts changes in their communicative behaviors. However, little is known about whether walking also shapes infants’ proximity to their adult social partners during everyday activities at home. Here we followed 89 infants (42 boys, 47 girls; 92% White, not Hispanic or Latino) longitudinally and documented connections between infant locomotion and infant-adult proximity on two timescales: (1) across developmental time, by comparing data from a session when infants could only crawl to a later session when they could walk (M walk onset = 12.15 months, range = 8-15); and (2) in real time, by testing whether the amount of time that infants spent in motion (regardless of their locomotor status) related to their interpersonal distance to adults. The developmental transition to walking corresponded to a significant, but modest, decrease in infant-adult proximity. Infants’ moment-to-moment locomotion, however, was strongly related to patterns of interpersonal distance: infants who spent more time in motion spent less time near adults and instigated more proximity transitions, resulting in shorter and more dispersed bouts of proximity throughout sessions. Findings shed new light on how infants’ motor achievements can reverberate across other domains of development, and how changes in infant development that researchers often observe over months arise from infants’ moment-to-moment experiences.     

The Infant Orienting With Attention Task: Assessing the Neural Basis of Spatial Attention in Infancy

Infant visual attention develops rapidly over the first year of life, significantly altering the way infants respond to peripheral visual events. Here, we present data from 5‐, 7‐, and 10‐month‐old infants using the Infant Orienting With Attention (IOWA) task, designed to capture developmental changes in visual spatial attention and saccade planning. Results indicate rapid development of spatial attention and visual response competition between 5 and 10 months. We use a dynamic neural field (DNF) model to link behavioral findings to neural population activity, providing a possible mechanistic explanation for observed developmental changes. Together, the behavioral and model simulation results provide new insights into the specific mechanisms that underlie spatial cueing effects, visual competition, and visual interference in infancy.     

How Does Learning Impact Development in Infancy? The Case of Perceptual Organization

Pattern perception and organization are critical functions of the visual cognition system. Many organizational processes are available early in life, such that infants as young 3 months of age are able to readily utilize a variety of cues to organize visual patterns. However, other processes are not readily evident in young infants, and their development involves perceptual learning. We describe a theoretical framework that addresses perceptual learning in infancy and the manner in which it affects visual organization and development. It identifies five kinds of experiences that induce learning, and suggests that they work via attentional and unitization mechanisms to modify visual organization. In addition, the framework proposes that this kind of learning is abstract, domain general, functional at different ages in a qualitatively similar manner, and has a long‐term impact on development through a memory reactivation process. Although most models of development assume that experience is fundamental to development, very little is actually known about the process by which experience affects development. The proposed framework is an attempt to account for this process in the domain of perception.     

Understanding developmental cascades and experience: Diversity matters

This Presidential Address is aimed at considering how infant development can be understood in terms of developmental cascades. Adopting a developmental cascades approach may be especially useful for understanding development in infancy, when changes occur in multiple domains over relatively short time spans. Thinking about change in terms of developmental cascades highlights the role of the input in development, both in terms of how the input changes with development and in terms of how differences in the input lead to different developmental pathways. I reflect on how a developmental cascade perspective can help us understand the role of input and how development builds as the emergence and refinement of abilities changes the input and shapes the developmental pathways. Further, I emphasize that infants develop despite differences in the input, and that when studying infant development we should seriously consider the diversity of experience that infants encounter and how differences in experience (and input) shape the developmental cascade.     

Blinking Bird Brains: A Timing Specific Deficit in Auditory Learning in Quail Hatchlings

Contingency perception is critical during infancy, providing the basis for the continuous learning (and re‐learning) of the relation between the developing body, self‐produced actions, and the environment. Nevertheless, relatively few studies have systematically examined the spatiotemporal parameters that optimize learning during development. Here, we present a series of experiments exploring a novel timing‐specific deficit in auditory learning in an animal model, the bobwhite quail (Colinus virginianus). In this paradigm, chicks vocalize to hear playback of an unfamiliar maternal call and are later tested for their filial preference for that call over a novel maternal call. Rather than a simple, hyperbolic decline in learning with increased delay between chick vocalization and playback, we found a window—450–900 msec after chicks ceased vocalizing—in which chicks appeared to have difficulty learning and forming a preference for the maternal call. This deficit nonetheless occurred only when the spatial location of call playback switched semi‐randomly during training, suggesting an attentional explanation for this deficit. Our findings indicate that optimization of the temporal parameters in operant paradigms with infants can be complex, particularly if tasks requiring the switching of attention between spatial locations. Our findings may thus be instructive for other developmental research with infants employing operant components.     

Parental Death and Subjective Age: Indelible Imprints from Early in the Life Course?*

Past research suggests that sustaining a young identity helps adults maintain a greater sense of well‐being. The experience of subjective aging, however, is not a spontaneous phenomenon, but stems from lifelong developmental experiences. Drawing from writings on the life course and self‐concept, I consider how parental death in childhood shapes subjective age in adulthood. To examine the effects of maternal and paternal death on subjective age, I employ the Midlife Development in the United States Study (MIDUS). A series of linear regression analyses indicates that maternal death during childhood is associated with an older subjective age in adulthood, death of a father does not have a similar influence on subjective age, and that the effect on subjective age is stronger if maternal death occurred during childhood than during other periods of the life course. The findings highlight interconnections between timing of transitions in the life course, linked lives, and the development of self‐concept. Subjective age in adulthood seems to hinge on important biographical experiences from childhood, such as parental death, though the processes differ by the gender of the deceased parent.     

“Above the below”: body trauma as spectacle in social/media space

The exposure and, more particularly, self‐exposure of psychological and bodily trauma has become the central feature of our “postdocumentary” culture. TV talk shows, observational documentary, life‐style programming and reality television all facilitate the exhibition and consumption of personal pain and suffering (as well as joy and individual success). Generally speaking, this showcasing of personal trauma is a gendered one; with many of the established and newer formats dismissed as feminised media culture; with few, if any, intellectual pretensions. This is partly the case because the domain of emotional suffering, at least, has been conventionally designated a “feminine” one, with women especially, licensed to speak about bodily or psychological insecurity, vulnerability or damage. When “masculine” damage or trauma is at stake, its presentation and articulation in media culture takes on quite different forms and meanings. Bearing in mind this context, this essay examines an example of the new hybrid of reality TV and performance piece: the David Blaine event entitled “Above the Below”. It does so in order to explore the meanings, symbolics and ethics of the current specularisation of bodily trauma in social and media space; revealing the multiple ways in which an ethics of the self and of becoming is articulated in a popular form. Ultimately, the aim is to make more complex our understanding of “the apparently oxymoronic ‘popularity’ of trauma” as cultural text (Radstone , p. 189).

This dissolution of the boundary between inside and outside gives rise to a fourth aspect of the felt experience of physical pain, an almost obscene conflation of private and public. It brings with it all the solitude of absolute privacy with none of its safety, all the self‐exposure of the utterly public with none of its possibility for camaraderie or shared experience. Artistic objectifications of pain often concentrate on this combination of isolation and exposure. (Scarry , p. 53)     

The Effect of Excessive Crying on the Development of Emotion Regulation

The goal of this study was to examine the effect of excessive crying in early infancy on the development of emotion self‐regulation. Cry diaries were used to categorize excessive criers and typical criers at 6 weeks of age. At 5 and 10 months of age, infants and mothers participated in procedures to elicit infant reactivity and regulation during a frustration task and maternal sensitivity and intrusiveness during a free‐play session. Last, maternal ratings of temperament were obtained. Results revealed excessive criers to show higher levels of negative reactivity than typical criers. Excessive criers also demonstrated lower regulation, but this finding was only significant for male infants. Boys in the excessive criers group exhibited the lowest level of emotion self‐regulation. Maternal behavior and ratings of temperament at 5 and 10 months failed to distinguish the 2 cry groups. The findings suggest that excessive crying may influence the developmental trajectory of the ability of boys to self‐regulate emotion. The hypothesized processes involved in this outcome are discussed.     

Experiencing Sampling Research from Its Beginnings into the Future

Early experience sampling research sought to map the ecology of adolescents’ lives. Its contributions include discovery of similar patterns in psychological states across diverse samples: positive emotions with friends, more negative states alone, high challenge but low motivation during schoolwork, and wider variability in teens’ than adults’ emotions, including more frequent extreme positive states. Recent ambulatory assessment research has expanded this mission and methods in valuable ways. Yet it still demands problem‐solving (e.g., engaging participants, formulating analyses that represent teens’ complex lives). A promising innovation is use of micro‐longitudinal analyses to examine sequential processes (e.g., linkages between stress–coping–emotions; relationship episodes). Qualitative data can add “zones” for development of empirically‐based theory about daily processes, such as adolescents’ meaning‐making and learning self‐regulation.     

The Use of Mindfulness Training to Create an ‘Accompanying Place’ for Social Work Students

Social work students experience emotional stress while having to perform and meet expectations from both academy and field. They may often feel physically and emotionally overwhelmed while struggling to make the time and space to fully process the varied experiences involved. There seems to be an unmet need for an ‘accompanying place’ where thoughts, feelings and dilemmas can be observed in a non‐evaluative way. Mindfulness has evolved lately as an efficient therapeutic technique in therapy. This paper describes a technique that applies mindfulness meditation in a group format in order to create a broader and richer learning experience that answers students' emotional needs. The group met for eight weeks. Its goals were to enhance self‐awareness and increase emotional support in handling field and academic stressors while experiencing different states of consciousness. Findings show that students were able to acquire new knowledge about themselves, experience autonomy in learning self‐containment and regulation, and gain insights regarding their professional self‐concept. Significance for social work training is discussed.     

Triangulation and Theoretical Understanding

The more recent interpretation of triangulation in social and educational research was summarised and examined with reference to theory triangulation applied in an empirical study. The construction of special educational needs (SEN) from the individual experiences of a sample of SEN co‐ordinators and SEN teachers, parents, and adolescents with emotional and behavioural difficulties or physical disabilities were interpreted from the perspectives of personal construct theory, bio‐psycho‐social model, socio‐psychological analysis, bioecological model of human development and a developmental model of self‐understanding. Their points of convergence and divergence enriched and extended theoretical understanding. The focus on the ‘verstehen’ psychological level of analysis and on forging closer theory, concept and data connections influenced the range of theory choice. This instance of theory triangulation casts doubts on the Duhem‐Quine thesis of underdetermination.     

Positive Effects of Talking About the Negative: Family Narratives of Negative Experiences and Preadolescents' Perceived Competence

Family narratives about the past are an important context for the socialization of emotion, but relations between expression of negative emotion and children's emerging competence are conflicting. In this study, 24 middle‐class two‐parent families narrated a shared negative experience together and we examined the process (initiations and collaborations) and function (the expression and explanation of emotions) of co‐constructed narratives in relation to preadolescents' perceived competencies and self‐esteem. Family narratives in which specific emotions were expressed and explained in a collaborative fashion, especially negative emotion, were positively related to preadolescents' reported competencies and self‐esteem, whereas family narratives that expressed general positive emotion were negatively related to preadolescents' perceived competencies. Implications of family narratives about emotional events, specifically the ways in which families discuss emotion, in relation to preadolescents' self‐development are discussed.     

Categorical Perception of Facial Emotions in Infancy

Categorical perception, indicated by superior discrimination between stimuli that cross categorical boundaries than between stimuli within a category, is an efficient manner of classification. The current study examined the development of categorical perception of emotional stimuli in infancy. We used morphed facial images to investigate whether infants find contrasts between emotional facial images that cross categorical boundaries to be more salient than those that do not, while matching the degree of differences in the two contrasts. Five‐month‐olds exhibited sensitivity to the categorical boundary between sadness and disgust, between happiness and surprise, as well as between sadness and anger but not between anger and disgust. Even 9‐month‐olds failed to exhibit evidence of a definitive category boundary between anger and disgust. These findings indicate the presence of discrete boundaries between some, but not all, of the basic emotions early in life. Implications of these findings for the major theories of emotion representation are discussed.     

The Development of Selective Attention Orienting is an Agent of Change in Learning and Memory Efficacy

This study examined whether the developmental transition from facilitation‐based orienting mechanisms available very early in life to selective attention orienting (e.g., inhibition of return, IOR) promotes better learning and memory in infancy. We tested a single age group (4‐month‐olds) undergoing rapid development of attention orienting mechanisms. Infants completed a spatial cueing task designed to elicit IOR, in which cat or dog category exemplars consistently appeared in either the cued or noncued locations. Infants were subsequently tested on a visual paired comparison of exemplars from these cued and noncued animal categories. As expected, infants showed either facilitation‐based orienting or the more mature IOR‐based orienting during spatial cueing/encoding. Infants who demonstrated IOR‐based orienting showed memory for both specific exemplars and broader category learning, whereas those who showed facilitation‐based orienting showed weaker evidence of learning. Attention orienting also interacted with previous pet experience, such that the number of pets at home influenced learning only when infants engaged facilitation‐based orienting during encoding. Learning in the context of IOR‐based orienting was stable regardless of pet experience, suggesting that selective attention serves as an online learning mechanism during visual exploration that is less sensitive to prior experience.     

A life course approach: research orientations and future challenges

The need to study lifelong changes in health and functioning has resulted in increasing emphasis on a life course approach in different fields of inquiry. The aim of this approach is to explore how biological, psychological, and social risk factor trajectories, acting across the entire life course, influence age-related diseases, functional decline, and disability. The importance of the first years of life upon later development and adult characteristics was generally recognized already in the first half of the twentieth century, but it was not until the 1990s that different strands of medical and social research converge in the field of life course epidemiology, in which epidemiological processes are approached using different models such as biological programming, critical periods, pathways, and accumulation. The biological programming model holds that organ development in utero and early infancy determines the maximum functional capacity that an individual can attain and influences the development of certain chronic diseases later in life. The critical period model extends the idea to include child development and key social transitions over the entire life course. The pathway model focuses on the cumulative effect of life events along the developmental trajectories, with early advantage or disadvantage setting a person on a pathway to a later etiologically important exposure. The accumulation model describes the underlying social, behavioral, and biological processes that drive the impact of the life course on health. The growing focus on life course determinants of aging also has implications for studies of long-term changes in physical activity and their role in determining both gains and losses of health and functioning with aging. A life course approach presents great challenges for the continued development of testable theoretical models and effective study design and analysis.     

Child,Caregiver, and Temperament Contributions to Infant Joint Attention

Little is known about variables that may contribute to individual differences in infant joint attention, or the coordination of visual attention with a social partner. Therefore, this study examined the contributions of caregiver behavior and temperament to infant joint attention development between 9 and 12 months. Data were collected from 57 infants using a caregiver–infant paradigm, an infant–tester paradigm, and a parent report of infant temperament. Nine‐month measures of caregiver scaffolding and infant initiating joint attention (IJA) with testers were significantly related to 12‐month infant IJA with testers. A temperament measure of positive emotional reactivity was related to 9‐month IJA, and a measure of negative emotional reactivity was related to 12‐month IJA. Temperament and caregiver scaffolding measures, however, were not associated with the development of infant responding to joint attention. These results further the understanding of the multiple processes that contribute to joint attention development in infancy, and support the hypothesis that initiating and responding measures tap different aspects of joint attention development.
