Variable coordination of eye and head movements during the early development of attention: A longitudinal study of infants aged 12–36 months

This longitudinal study investigated the effects of attentional development on peripheral stimulus localization by analyzing the eye and head movements of toddlers as they matured from 12 to 36 months. On each trial of an experiment, a central fixation point and a 30° peripheral stimulus were presented, such that in the gap condition the fixation disappeared 300 ms before the peripheral stimulus, whereas in the no-overlap condition it disappeared simultaneously as the peripheral stimulus, and in the overlap condition the fixation remained present when the peripheral target occurred. Results showed that eye and head movement latencies were highly correlated in all conditions and ages. However, at 12 months, head movements were as fast as eye movements, whereas during the subsequent development, eye movements became increasingly faster than head movements. These findings are indicative of a transition between 12 and 36 months due either to a change in attentional control, or to changes in the size of the visual field in which only eye movements occur.     

Individual differences in disengagement of fixation and temperament: Longitudinal research on toddlers

It has been suggested that a shift occurs in the brain's control system from the orienting network in infancy to the executive network by the age of 3–4 years; however, there has been little empirical evidence of this shift during toddlerhood. Therefore, the present study examined how the orienting system in infancy is related to an effortful control system at a later age. Children were assessed longitudinally at 12, 18, 24, and 36 months of age, using a gap-overlap task in which dynamic geometrical-shape stimuli were presented. Parents completed temperament questionnaires about the children at each age. A delayed-gratification task was also given to 36-month-olds. Overall, saccadic latencies in the gap-overlap task were significantly faster at 36 months. At all ages, responses were slower during overlap trials than during gap or no-overlap trials. Longer latencies in the overlap condition were associated with low temperamental orienting/regulation scores at 12 months but with high effortful control scores at 18 and 24 months. The associations at 18 and 24 months are thought to represent a genuine positive association between effortful control and sustained and focused attention.     

Effects of different facets of paternal and maternal control behaviour on early adolescents' perceived academic competence

The purpose of this study was to examine how different aspects of paternal and maternal control behaviours influence the perceived academic competence of early adolescents indirectly via their engagement with school. The analyses are based on a longitudinal study with two waves that were separated by 12 months. The participants were 228 early adolescents (50.4% girls) with an average age of 11.62 years (SD = .41) at the outset. Structural equation modeling analyses using bootstrapping procedures revealed that parental supervision was indirectly related to the perceived academic competence of adolescents via their engagement with schools, whereas parental authoritarian control was only linked to engagement with school. The discussion focuses on the multifaceted nature of parental control and the importance of both parents for the academic success of adolescents.     

Synchronous and time-lagged effects between occupational self-efficacy and objective and subjective career success: Findings from a four-wave and 9-year longitudinal study

We integrated research on the dimensionality of career success into social-cognitive career theory and explored the positive feedback loop between occupational self-efficacy and objective and subjective career success over time (self-efficacy → objective success → subjective success → self-efficacy). Furthermore, we theoretically accounted for synchronous and time-lagged effects, as well as indirect reciprocity between the variables. We tested the proposed model by means of longitudinal structural equation modeling in a 9-year four-wave panel design, by applying a model comparison approach and indirect effect analyses (N = 608 professionals). The findings supported the proposed positive feedback loop between occupational self-efficacy and career success. Supporting our time-based reasoning, the findings showed that unfolding effects between occupational self-efficacy and objective career success take more time (i.e., time-lagged or over time) than unfolding effects between objective and subjective career success, as well as between subjective career success and occupational self-efficacy (i.e., synchronous or concurrently). Indirect effects of past on future occupational self-efficacy via objective and subjective career success were significant, providing support for an indirect reciprocity model. Results are discussed with respect to extensions of social-cognitive career theory and occupational self-efficacy development over time.     

Self-compassion and body-related self-conscious emotions: Examining within- and between-person variation among adolescent girls in sport

ObjectivesSelf-compassion protects against the occurrence of negative body image experiences and may be particularly useful in defending against negative body- and appearance-related self-conscious emotions in sport. The aim of this study was to examine within- and between-person associations between self-compassion and appearance-related self-conscious emotions.Design & MethodIn a three-year longitudinal cohort study, adolescent girls involved in organized sport (N = 518, M_age = 14.02 ± 1.38) completed yearly self-reports of self-compassion, body- and appearance-related shame, guilt, embarrassment, and envy.ResultsBased on findings from multilevel models, higher levels of both average and time-varying self-compassion were associated with lower levels of body-related shame, guilt, embarrassment, and envy. Specifically, girls reported lower levels of negatively valanced self-conscious emotions when self-compassion was higher than usual.ConclusionsThese findings support previous accounts on the utility of self-compassion as a buffer against negative body image experiences and extend these findings to appearance-related self-conscious emotions in the sport context. In light of the declining levels of self-compassion for girls in adolescence, it is important to focus intervention efforts on cultivating self-compassion to protect girls from negative body-related emotional experiences in sport.     

The dynamics of purchasing an electric vehicle – A prospective longitudinal study of the decision-making process

This paper presents the results of a longitudinal prospective study which followed 113 people interested in the purchase of an electric vehicle for a period of two months. Based on an adapted stage model of self-regulated behavioral change (Bamberg, 2013b), a short online questionnaire with a stage diagnostic and the measurement of central model constructs was administered to the participants every second day. The analysis shows that 85% of transitions between the stages occur along the paths of the stage model. Stage transitions are preceded by increases in goal intentions and implementation intentions during the week before the transition. Intentions are predicted by most of the expected model constructs, but the effects were different on the between-person and the within-person level. The average stage durations are between two and three weeks. Implications of the study for research on stage models and practice are discussed.     

Goals and plans for Big Five personality trait change in young adults

Four studies were conducted on young adults’ goals and plans to change personality traits. In Study 1, a new trait change goal assessment tool, the BF-TGI, found Neuroticism to be the most frequently cited trait for a change goal. In Study 2, data was gathered from the UK, Iran and China. Iran showed a higher prevalence of normative change goals than the UK and China. Study 3 investigated plans to change traits. Extraversion and Conscientiousness plans were more specific than for the other traits. Study 4 investigated whether goals and plans to change predict change over 12 months, and found that goals and plans to change Conscientiousness and Neuroticism predicted change in the opposite direction to the goal.     

40,000 memories in young teenagers: Psychometric properties of the Autobiographical Memory Test in a UK cohort study

Although the Autobiographical Memory Test (AMT) is widely used its psychometric properties have rarely been investigated. This paper utilises data gathered from a 10-item written version of the AMT, completed by 5792 adolescents participating in the Avon Longitudinal Study of Parents and Children, to examine the psychometric properties of the measure. The results show that the scale derived from responses to the AMT operates well over a wide range of scores, consistent with the aim of deriving a continuous measure of over-general memory. There was strong evidence of group differences in terms of gender, low negative mood, and IQ, and these were in agreement when comparing an item response theory (IRT) approach with that based on a sum score. One advantage of the IRT model is the ability to assess and consequently allow for differential item functioning. This additional analysis showed evidence of response bias for both gender and mood, resulting in attenuation in the mean differences in AMT across these groups. Implications of the findings for the use of the AMT measure in different samples are discussed.

Neurocognitive profiles of preterm infants randomly assigned to lower or higher hematocrit thresholds for transfusion

Objective: Preterm infants are frequently transfused with red blood cells based on standardized guidelines or clinical concerns that anemia taxes infants' physiological compensatory mechanisms and thereby threatens their health and well-being. The impact of various transfusion guidelines on long-term neurocognitive outcome is not known. The purpose of this study is to evaluate long-term neurocognitive outcome on children born prematurely and treated at birth with different transfusion guidelines.

Methods: Neurocognitive outcomes were examined at school age for 56 preterm infants randomly assigned to a liberal (n?=?33) or restrictive (n?=?23) transfusion strategy. Tests of intelligence, achievement, language, visual-spatial/motor, and memory skills were administered. Between-group differences were assessed.

Results: Those in the liberal transfusion group performed more poorly than those in the restrictive group on measures of associative verbal fluency, visual memory, and reading.

Conclusions: Findings highlight possible long-term neurodevelopmental consequences of maintaining higher hematocrit levels.
