Abstract
Infants rely on developing attention skills to identify relevant stimuli in their environments. Although caregivers are socially rewarding and a critical source of information, they are also one of many stimuli that compete for infants' attention. Young infants preferentially hold attention on caregiver faces, but it is unknown whether they also preferentially orient to caregivers and the extent to which these attention biases reflect reward-based attention mechanisms. To address these questions, we measured 4- to 10-month-old infants' (N = 64) frequency of orienting and duration of looking to caregiver and stranger faces within multi-item arrays. We also assessed whether infants' attention to these faces related to individual differences in Surgency, an indirect index of reward sensitivity. Although infants did not show biased attention to caregiver versus stranger faces at the group level, infants were increasingly biased to orient to stranger faces with age and infants with higher Surgency scores showed more robust attention orienting and attention holding biases to caregiver faces. These effects varied based on the selective attention demands of the task, suggesting that infants' attention biases to caregiver faces may reflect both developing attention control skills and reward-based attention mechanisms.

The effects of parental presence on amygdala and mPFC activation during fear conditioning: An exploratory study. Dev Sci 2024:e13505.

Abstract
Learning safe versus dangerous cues is crucial for survival. During development, parents can influence fear learning by buffering their children's stress response and increasing exploration of potentially aversive stimuli. Rodent findings suggest that these behavioral effects are mediated through parental presence modulation of the amygdala and medial prefrontal cortex (mPFC). Here, we investigated whether similar parental modulation of amygdala and mPFC during fear learning occurs in humans. Using a within-subjects design, behavioral (final N = 48, 6-17 years, mean = 11.61, SD = 2.84, 60% females/40% males) and neuroimaging data (final N = 39, 6-17 years, mean = 12.03, SD = 2.98, 59% females/41% males) were acquired during a classical fear conditioning task, which included a CS+ followed by an aversive noise (US; 75% reinforcement rate) and a CS-. Conditioning occurred once in physical contact with the participant's parent and once alone (order counterbalanced). Region of interest analyses examined the unconditioned stress response by BOLD activation to the US (vs. implicit baseline) and learning by activation to the CS+ (vs. CS-). Results showed that during US presentation, parental presence reduced the centromedial amygdala activity, suggesting buffering of the unconditioned stress response. In response to learned stimuli, parental presence reduced mPFC activity to the CS+ (relative to the CS-), although this result did not survive multiple comparisons' correction. These preliminary findings indicate that parents modulate amygdala and mPFC activity during exposure to unconditioned and conditioned fear stimuli, potentially providing insight into the neural mechanisms by which parents act as a social buffer during fear learning. RESEARCH HIGHLIGHTS: (1)This study used a within-participant experimental design to investigate how parental presence (vs. absence) affects youth's neural responses in a classical fear conditioning task. (2)Parental presence reduced the youth's centromedial amygdala activation to the unconditioned stimulus (US), suggesting parental buffering of the neural unconditioned response (UR). (3)Parental presence reduced the youth's mPFC activation to a conditioned threat cue (CS+) compared to a safety cue (CS-), suggesting possible parental modulation of fear learning.

Abstract
The relevance of the study is due to the presence of a relationship that occurs between the emotional and intellectual development of the individual. Negative changes in the process of emotional development of a person lead to the fact that they are unable to use other structures, in particular, intelligence, and therefore develop harmoniously. As a basic emotion, fear is an integral part of the emotional field, as is the emotion of joy, sadness, and anger. Fear performs a protective function, but it also destroys the individual if it is irrational. The emotion of fear, arising in childhood, can be fixed and transformed into more acute manifestations, that is, into phobic disorders. Personality is formed under the influence of society, so a very important role in its development is played by models of upbringing in the family and those attitudes and prescriptions that a person learns from childhood. In adulthood, these patterns are manifested in the form of stereotypical behaviour, which substantially affects a person’s quality of life. Therefore, it is important to clarify how childhood fears can affect the individual in adulthood. The purpose of this study is to establish a link between childhood fears and stereotypical behaviour. A number of methods and techniques were used to achieve this goal, including theoretical (analysis, synthesis, generalisation) and practical (D. McLain’s general tolerance for uncertainty scale; tolerance-intolerance of ambiguity questionnaire by T.V. Kornilova; questionnaire of childhood fears). The results of the study show that in the case when a person cannot safely live through fears as a child, they have an impact on the psychological well-being of the individual, which encourages the formation of psychological problems. It is proved that as a result of gender stereotypes in education, male and female fears formed in childhood differ markedly. Therewith, it is noted that certain stereotypes have a positive meaning in a person’s life if they do not suppress their psychological development. The research materials will be useful for practical psychologists in the education and social fields, and teachers
