A preliminary study on the relationship between characteristics of TV content and delayed speech development in young children

Our previous population survey of 18-month-old children suggested an association between delayed language development and heavy TV viewing. We therefore collected all 85 videos described as children's favorites in that questionnaire to examine relationships between the characteristics of habitually viewed videos and language development. In the language delayed group, compared to the non-delayed group, the types of videos preferred more were “realistic animations” and “baby education” and the characteristics of videos were contained few close-ups of characters facing viewers, continued uninterruptedly between stories, had constant movement or transformation of characters, had a high frame rate of animation, and that adults readily kept on watching the videos even with the sound off. These characteristics were seen more in videos the above two types. These findings imply that habitual television/video viewing with characteristics that are not apt to elicit parent–child communication for long hours may affect delayed language development in young children.

Early predictors of career development: A 10-year follow-up study

This paper presents empirical findings from a 10-year longitudinal study of the educational and occupational socialization of 445 participants who were about 7 years old when first tested, and about 17 years old at the fourth time of measurement. In addition to collecting psychological measurements from the participants, behavioral reports were collected from significant others, specifically parents and teachers. Findings demonstrated that the life/career evolution of the participants can be understood only when taking into account the dynamic interaction between the unique personal characteristics of individuality of each person and the psychosocial theatre within which the person’s development takes place. Using the life-span, life-space framework of Super, and the Developmental-Contextual model from Vondracek, different emerging early predictors with unique impact on the process of educational and occupational socialization were identified, especially with respect to the probability of dropping out of school. Results in terms of gender, parental influences, psychological characteristics, and social context are discussed with regard to their potential implications for psychological interventions in schools, families, and occupational settings, as well as with regard to personal counseling in what concerns the management of life circumstances and behavioral ecosystems.

What the eyes already ‘know’: using eye movement measurement to tap into children's implicit numerical magnitude representations

To date, a number of studies have demonstrated the existence of mismatches between children's implicit and explicit knowledge at certain points in development that become manifest by their gestures and gaze orientation in different problem solving contexts. Stimulated by this research, we used eye movement measurement to investigate the development of basic knowledge about numerical magnitude in primary school children. Sixty‐six children from grades one to three (i.e. 6–9 years) were presented with two parallel versions of a number line estimation task of which one was restricted to behavioural measures, whereas the other included the recording of eye movement data. The results of the eye movement experiment indicate a quantitative increase as well as a qualitative change in children's implicit knowledge about numerical magnitudes in this age group that precedes the overt, that is, behavioural, demonstration of explicit numerical knowledge. The finding that children's eye movements reveal substantially more about the presence of implicit precursors of later explicit knowledge in the numerical domain than classical approaches suggests further exploration of eye movement measurement as a potential early assessment tool of individual achievement levels in numerical processing.

Individual and contextual factors: An interactionist approach to understanding employee self-development

While prior research has identified several individual characteristics and contextual factors influential on an employee’s quantity of self-development participation, no research has examined multiplicative effects among these factors. This study investigated person-situation interactions among five individual characteristics (e.g., openness to experience) and the contextual factor of workplace support for self-development. This study also sought to investigate the link between proactive personality and self-development participation, a promising individual characteristic that has received little attention in the self-development literature. Data collected from 136 employees demonstrates significant interactions between workplace support with learning goal orientation, openness to experience, and conscientiousness. As hypothesized, workplace support is more strongly, positively linked to quantity of self-development participation for employees lower in these traits. In contrast, the provision of external support is rather inconsequential for those high in these traits, as these employees demonstrate an internal propensity to engage in voluntary development regardless of the support available. Regarding proactive personality, a significant positive relationship was observed with self-development quantity. Further, although the expected interaction between proactive personality and workplace support did not reach statistical significance (p = .056), it was in the hypothesized direction.

Measuring psychological need states in sport: Theoretical considerations and a new measure

ObjectivesResearch guided by Self-determination Theory (Deci & Ryan, 1985; Ryan & Deci, 2017) has repeatedly demonstrated the importance of focusing on both the bright (satisfaction) and dark (frustration) sides of the three basic psychological needs. Recently, researchers have also argued for the utility of assessing a third need state, that of “unfulfillment”. In this paper, we outline an effort to develop and provide initial validity evidence for scores of a new multidimensional and sport-specific measure, the Psychological Need States in Sport-Scale (PNSS-S), to assess the satisfaction, frustration, and unfulfillment of all three needs.MethodIn Study 1, we developed 46 candidate items, and tested evidence for the factorial structure of the responses to the newly developed items, internal consistency and discriminant validity of the subscale scores. Following refinement, the replication of the favored model was tested using an independent sample of athletes in Study 2. Evidence for the nomological network of the subscales of the new measure was also demonstrated in Study 2.ResultsFactor models incorporating all three need states showed poor fit with the data. However, following post-hoc modifications, a six-factor model assessing the need states of satisfaction and frustration, separately for autonomy, competence, and relatedness, was found to have good fit to the data. After refinement, the 29-item six-factor model was found to demonstrate good fit, good standardized factor loadings, factor correlations in the expected directions, and acceptable estimates of internal consistency in Study 2. Tests of nomological networks showed that the six need states were significantly predicted by contextual autonomy, competence, and relatedness support/thwarts as expected. Autonomy and competence need satisfaction were significantly associated with engagement; and competence and relatedness need satisfaction were significantly associated with positive affect. In addition, autonomy and competence need frustration were significantly associated with exhaustion and all three need frustration states significantly predicted negative affect.ConclusionsA tripartite conceptualization of the need states was not empirically supported. Nevertheless, the PNSS-S makes a unique contribution to the sport literature, as it represents the first sport-specific measure of six distinct, yet, correlated states of the satisfaction and frustration of autonomy, competence, and relatedness needs.     

Association of prenatal attachment and early childhood emotional,behavioral, and developmental characteristics: A longitudinal study

This study examines the associations between prenatal attachment and child development, socioemotional behavioral problems, and competence at early childhood. It also inquires whether maternal depression and anxiety at the prenatal period and at early childhood are associated with child outcomes. The study consisted of 83 mothers and their children. Data regarding the prenatal attachment, depression, and anxiety were collected during Weeks 28 to 40 of gestation. When the children were 21 to 31 months old, the Brief Infant and Toddler Social Emotional Assessment (BITSEA) and the Ankara Developmental Screening Inventory (ADSI) were applied to children along with Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) administered to mothers. Results showed that prenatal attachment scores significantly correlated with BITSEA-Competency subscale scores and ADSI total scores at early childhood, r(83) = 0.246, P = .025, and r(82) = 0.316, P = .004, respectively. Prenatal attachment levels were found to be the predictors of both behavioral and emotional competence and development at early childhood, b = 0.081, t(83) = 2.273, P = .014, and b = 0.281, t(83) = 3.225, P = .002, respectively. In addition, prenatal attachment was shown to be even a stronger predictor of development than was worsening maternal depression at early childhood, b = −0.319, t(83) = 2.140, P = .035. Our results indicate that fostering prenatal attachment may be beneficial for better infant outcomes at early childhood.
