- Four-, 6-, and 11-month old infants were presented with movies in which two adult actors conversed about everyday events, either by facing each other or looking in opposite directions. Infants from 6 months of age made more gaze shifts between the actors, in accordance with the flow of conversation, when the actors were facing each other. A second experiment demonstrated that gaze following alone did not cause this difference. Instead the results are consistent with a social cognitive interpretation, suggesting that infants perceive the difference between face-to-face and back-to-back conversations and that they prefer to attend to a typical pattern of social interaction from 6 months of age.

- Cortisol in hair is a new biomarker assessing long-term hypothalamic-pituitary-adrenal (HPA) axis activity, which is related to emotion regulation. We compare hair cortisol concentrations (HCC), in clinically referred children with disruptive mood dysregulation disorder (DMDD) (n = 19), children with other types of psychological disorders (n = 48), and healthy subjects (n = 36). We also investigate the association between HCC and irritability, age, and sex. Our results show that children with DMDD or other types of psychological disorders have higher HCC than healthy subjects, p < .001, ?(2)(p) = .39. No difference between children with DMDD and those with other types of psychological disorders was found, p = .91, nor an association between HCC and irritability in the clinical sample, p = .32. We found a significant negative correlation between HCC and age in those with DMDD, r = -0.54, p < .05, but not in the normative sample, r = -0.20, p = .25. No differences in HCC between girls and boys were found in the normative sample, p = .49. Children in need of psychological treatment, including those with DMDD, seem to have dysregulated HPA-axis activity over time. Excessive accumulated cortisol concentrations in hair could be an indicator of a psychological disorder in children.

- Six- and 12-month-old infant’s eye movements were recorded as they observed feedingactions being performed in a rational or non-rational manner. Twelve-month-olds fixatedthe goal of these actions before the food arrived (anticipation); the latency of these gazeshifts being dependent (r = .69) on infants life experience being feed. In addition, 6- and12-month-olds dilated their pupil during observation of non-rational feeding actions. Thiseffect could not be attributed to light differences or differences in familiarity, but wasinterpreted to reflect sympathetic-like activity and arousal caused by a violation of infant’sexpectations about rationality. We argue that evaluation of rationality requires less experiencethan anticipations of action goals, suggesting a dual process account of preverbalinfants’ everyday action understanding.

Teleological Reasoning in 4-Month-Old Infants : Pupil Dilations and Contextual Constraints

- Four-month-old infants were presented with feeding actions performed in a rational or irrational manner. Infants reacted to the irrational feeding actions by dilating their pupils, but only in the presence of rich contextual constraints. The study demonstrates that teleological processes are online at 4 months of age and illustrates the usefulness of pupil dilations as a measure of social cognitive processes early in infancy.

The Development and Neural Basis of Pointing Comprehension

- The neurological correlates of pointing comprehension in adults and 8-month-old infants are explored. Both age groups demonstrate differential activation to congruent and incongruent pointing gestures over posterior temporal areas. The functional similarity of the adult N200 and the infant P400 component suggests that they might have a common source.

The development of joint visual attention : A longitudinal study of gaze following during interactions with mothers and strangers
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Two- to 8-month-old infants interacted with their mother or a stranger in a prospective longitudinal gaze following study. Gaze following, as assessed by eye tracking, emerged between 2 and 4 months and stabilized between 6 and 8 months of age. Overall, infants followed the gaze of a stranger more than they followed the gaze of their mothers, demonstrating a stranger preference that emerged between 4 and 6 months of age. These findings do not support the notion that infants acquire gaze following through reinforcement learning. Instead, the findings are discussed with respect to the social cognitive framework, suggesting that young infants are driven by social cognitive motives in their interactions with others.
