Developmental patterns of emotion regulation in toddlerhood: Examining predictors of change and long‐term resilience

Emotion regulation is critical for optimal functioning across a wide range of domains and may be even more important for individuals in high‐risk environments. While evidence suggests that childhood is generally a period of emotion regulation growth and development, research is needed to examine factors that may contribute to deviations from a typical trajectory. In a prospective study of 1,905 children, latent class growth analysis (LCGA) was used to identify trajectory groups of emotion regulation across toddlerhood (age 14–36 months), examine predictors of those trajectory groups from child temperament, parenting behaviors, and environmental risk, and explore predictions of resilience in 5th grade from the identified groups. LGCA supported a three‐class model, with a Stable Incline group, a Decline group, and a Catch‐Up group. Child negative emotionality, positive and negative parenting, and environmental risk predicted group membership. These trajectory groups in toddlerhood were predictive of child resilient functioning in the 5th grade. Our findings highlight the importance of utilizing developmental models of emotion regulation and provide implications for prevention and early intervention services to enhance emotion regulation development in early childhood.     

Reading Emotion From Mouse Cursor Motions: Affective Computing Approach

Affective computing research has advanced emotion recognition systems using facial expressions, voices, gaits, and physiological signals, yet these methods are often impractical. This study integrates mouse cursor motion analysis into affective computing and investigates the idea that movements of the computer cursor can provide information about emotion of the computer user. We extracted 16–26 trajectory features during a choice‐reaching task and examined the link between emotion and cursor motions. Participants were induced for positive or negative emotions by music, film clips, or emotional pictures, and they indicated their emotions with questionnaires. Our 10‐fold cross‐validation analysis shows that statistical models formed from “known” participants (training data) could predict nearly 10%–20% of the variance of positive affect and attentiveness ratings of “unknown” participants, suggesting that cursor movement patterns such as the area under curve and direction change help infer emotions of computer users.     

Structuring of Early Reaching Movements: A Longitudinal Study

Reaches, performed by 5 infants, recorded at 19 weeks of age and every third week thereafter until 31 weeks of age, were studied quantitatively. Earlier findings about action units were confirmed. At all ages studied, movements were structured into phases of acceleration and deceleration. Reaching trajectories were found to be relatively straight within these units and to change direction between them. It was also found that at all ages, there was generally one dominating transport unit in each reach. The structuring of reaching movements changed in four important ways during the period studied. First, the sequential structuring became more systematic with age, with the dominating transport unit beginning the movement. Second, the duration of the transport unit became longer and covered a larger proportion of the approach. Third, the number of action units decreased with age, approaching the two-phase structure of adult reaching. Finally, reaching trajectories became straighter with age.     

Spiritual and Religious Implications of Aging with HIV: A Conceptual and Methodological Review

ABSTRACT

Spirituality and religious practices can buffer people from stressful life circumstances and promote positive biopsychosocial outcomes. The beneficial effects of spirituality and religious practices have been documented in aging and HIV. Unfortunately, little is known about spirituality and religious practices in older adults with HIV. As the number of older adults with HIV increases, with an estimated 91,000 adults over 50 being diagnosed with this disease in the United States, spirituality and religious practices may help HIV-positive people to age successfully. Crisis competence and spiritual trajectories are ways of conceptualizing spiritual development when confronting aging with a life-changing event such as a being diagnosed with HIV. Methodological issues in studying spirituality in adults aging with HIV are identified including defining spirituality and religiosity, heterogeneity of the population, timing of diagnosis, mode of transmission, sexual orientation, religious and cultural stigma, and hardiness. Implications for possible interventions are also posited.     

‘Theory of mind’ development of Pakistani children: Do preschoolers acquire an understanding of desire,pretence and belief in a universal sequence?

Research on “theory of mind” (TOM) suggests that a grasp of the mind develops universally and sequentially, but both these claims require testing in different cultural groups. Study 1, involving 72 preschoolers, showed the expected developmental transition on false belief tasks; 3 year olds were below statistical chance, while 4 year olds were at chance, representing a lag behind Western children. The same pattern of at chance (pretence, desire and belief) and below chance performance (false belief) was replicated in study 2 with 77 preschoolers (3–5 years) and corroborated the lag identified for some Asian countries. This deficient and varied timing of TOM performance is consistent with theories (social constructivist) supporting the role of social factors in TOM development. Moreover, significant inter-task correlations corroborate the need to broaden the research focus beyond false belief tasks.

Task specificity and the timing of discrete aiming movements

In discrete aiming movements the task criteria of time-minimization to a spatial target (e.g., Fitts, 1954) and time-matching to a spatial-temporal goal (e.g., Schmidt et al., 1979) tend to produce different functions of the speed-accuracy trade-off. Here we examined whether the task-related movement speed-accuracy characteristics were due to differential space-time trade-offs in time-matching, velocity-matching and time-minimizing task goals. Twenty participants performed 100 aiming trials for each of 15 combinations of task-type (3) and space-time condition (5). The prevalence of the primary types of sub-movement (none, pre-peak, post-peak, undershooting and overshooting) was determined from the kinematics of the movement trajectory. There were comparable distributions of trajectory sub-movement profiles and space-time movement outcomes across the three tasks at the short movement duration that became increasingly dissimilar over decreasing movement velocity and increasing movement time conditions. Movement time was the most influential variable in mediating sub-movement characteristics and the spatial/temporal outcome accuracy and variability of discrete aiming tasks – a role that was magnified in the explicit task demands of time-matching. The time-matching and time-minimization task goals in discrete aiming induce qualitatively different control processes that progressively contribute beyond the minimal time conditions to task-specific space-time accuracy and variability characteristics of the respective movement speed-accuracy functions.     

Individual differences in trajectories of arithmetical development in typically achieving 5- to 7-year-olds

The arithmetical performance of typically achieving 5- to 7-year-olds (N = 29) was measured at four 6-month intervals. The same seven tasks were used at each time point: exact calculation, story problems, approximate arithmetic, place value, calculation principles, forced retrieval, and written problems. Although group analysis showed mostly linear growth over the 18-month period, analysis of individual differences revealed a much more complex picture. Some children exhibited marked variation in performance across the seven tasks, including evidence of difficulty in some cases. Individual growth patterns also showed differences in developmental trajectories between children on each task and within children across tasks. The findings support the idea of the componential nature of arithmetical ability and underscore the need for further longitudinal research on typically achieving children and of careful consideration of individual differences.     

Why the brain needs language in order to be self-conscious

It has been argued that natural language, in the form of inner speech, plays a central role in self-consciousness. However, it is not quite clear why. In this paper, we present a novel answer to the why question. According to the thesis presented in this paper, the brain as a physical system is limited in observing itself and relies on the mediation of natural language for the reconstruction of its phase space trajectory. Drawing on knowledge gathered on the measurement of dynamical systems, we detail the unique properties of natural language that may support this reconstruction.
