Shyness and emotion‐processing skills in preschoolers: a 6‐month longitudinal study

The present study utilized a short‐term longitudinal research design to examine the hypothesis that shyness in preschoolers is differentially related to different aspects of emotion processing. Using teacher reports of shyness and performance measures of emotion processing, including (1) facial emotion recognition, (2) non‐facial emotion recognition, and (3) emotional perspective‐taking, we examined 337 Head Start attendees twice at a 24‐week interval. Results revealed significant concurrent and longitudinal relationships between shyness and facial emotion recognition, and either minimal or non‐existent relationships between shyness and the other aspects of emotion processing. Correlational analyses of concurrent assessments revealed that shyness predicted poorer facial emotion recognition scores for negative emotions (sad, angry, and afraid), but not a positive emotion (happy). Analyses of change over time, on the other hand, revealed that shyness predicted change in facial emotion recognition scores for all four measured emotions. Facial emotion recognition scores did not predict changes in shyness. Results are discussed with respect to expanding the scope of research on shyness and emotion processing to include time‐dependent studies that allow for the specification of developmental processes.

The relation between 3‐ and 15‐month olds' cry vocalizations and their mothers' affective involvement during inoculation

This study examined if infant immunization distress is related to their mothers' affective involvement prior to the injection. The duration of infant cry vocalizations and the amount of maternal behaviour before and after the syringe injection were observed in 18 mother–infant dyads, of whom nine comprised 3‐month‐old and nine 15‐month‐old infants. The maternal behaviour was scored in terms of various soothing strategies used to calm infants in distress. Infant cry duration, in both the 3‐ and the 15‐month olds, was associated with amount of maternal eye‐gaze before the injection. For the 15‐month olds, also face‐to‐face contact and rocking the infant was associated with more crying. Even though the small scale of the study warrants some caution in the interpretation, the overall findings suggest that young infants have a referential understanding of caregiver affective involvement prior to a stressor.

The relationship between sustained attention and cognitive performance in 17–24‐month old toddlers

The purpose of this study was to investigate individual differences in sustained attention and task performance with toddlers. Participants were 61 17–24‐month old toddlers. Indices of sustained attention (duration of attention and frequency of off‐task glances) were assessed during two 4 min problem solving tasks, and then related to problem solving and the mental scale of the Bayley scales of infant development‐II (BSID‐II). As expected, toddlers who attended to tasks for longer periods of time were more successful at problem solving, and had higher scores on the BSID‐II than toddlers who attended for shorter periods of time. In addition, older toddlers had longer attention spans, more frequent off‐task glances, and were more successful at problem solving than younger toddlers. Interestingly, toddlers with more frequent off‐task glances had longer attention spans, were more successful at problem solving, and had higher BSID‐II scores than peers with fewer off‐task glances. These findings suggest that although behavioural indices can be used to identify sustained attention, the relationship between behaviours thought to capture distractibility and attention is more complex than had been previously assumed. Results are discussed in the context of current theories of infant attention and cognitive performance. Copyright © 2000 John Wiley & Sons, Ltd.     

Association Learning with Own‐ and Other‐race Faces in three‐ and six‐month old infants – A longitudinal study

This longitudinal study assessed 133 Caucasian German infants at 3 and 6 months of age to investigate the influence of own‐race and other‐race faces as visual stimuli on association learning in the visual expectation paradigm (VExP). The study is related to the findings on the other‐race‐effect (ORE) which is said to emerge at 6 months of age. Caucasian faces were used as stimuli of a familiar ethnic category, whereas African faces were used as stimuli of an unfamiliar ethnic category. There was no significant difference between the two stimulus classes in infants' reaction time (RT) to stimulus shifts at 3 months. At 6 months of age, infants' RT decreased significantly in the Caucasian faces condition but not in the African faces condition. These results indicate that the processing of other‐race versus own‐race faces by the age of 6 months, which is also the relevant age for the onset of the ORE, has an important influence on the performance on the VExP.

Motivation and dropout in female handballers: a 21‐month prospective study

The purpose of this study was to test a motivational model of sport dropout that integrates the four‐stage causal sequence proposed by the Hierarchical Model of Vallerand ( 1997 ) and elements from achievement goal theory (Nicholls, 1989 ). The model posits that a task involving motivational climate facilitates, while an ego‐involving climate undermines, perceptions of competence, autonomy, and relatedness. In turn, feeling incompetent, non‐autonomous, and unrelated to others undermines self‐determined motivation toward handball which leads to the intention of dropping out of the game. Finally, such intentions are implemented later. Three hundred and thirty‐five female handballers completed a motivation questionnaire and were followed for 21 months. Results from structural equation modelling analyses provided basic support for the model. The findings are discussed in the light of their theoretical and applied implications.

The effects of adults' affective expression and direction of visual gaze on 12‐month‐olds' visual preferences for an object following a 5‐minute, 1‐day,or 1‐month delay

Between 12‐ and 14 months of age infants begin to use another's direction of gaze and affective expression in learning about various objects and events. What is not well understood is how long infants' behaviour towards a previously unfamiliar object continues to be influenced following their participation in circumstances of social referencing. In this experiment, we examined infants' sensitivity to an adult's direction of gaze and their visual preference for one of two objects following a 5‐min, 1‐day, or 1‐month delay. Ninety‐six 12‐month‐olds participated. For half of the infants during habituation (i.e., familiarization), the adults' direction of gaze was directed towards an unfamiliar object (look condition). For the remaining half of the infants during habituation, the adults' direction of gaze was directed away from the unfamiliar object (look‐away condition). All infants were habituated to two events. One event consisted of an adult looking towards (look condition) or away from (look‐away condition) an object while facially and vocally conveying a positive affective expression. The second event consisted of the same adult looking towards or away from a different object while conveying a disgusted affective expression. Following the habituation phase and a 5‐min, 1‐day, or 1‐month delay, infants' visual preference was assessed. During the visual preference phase, infants saw the two objects side by side where the adult conveying the affective expression was not visible. Results of the visual preference phase indicate that infants in the look condition showed a significant preference for object previously paired with the positive affect following a 5‐min and 1‐day delay. No significant visual preference was found in the look condition following a 1‐month delay. No significant preferences were found at any retention interval in the look‐away condition. Results are discussed in terms of early learning, social referencing, and early memory.     

Measures of infant behavioral and physiological state regulation predict 54‐month behavior problems

This study investigated whether measures of infant temperament, regulatory disorders, and physiological reactivity and concurrent measures of family environment were predictors of child behavior problems at 54 months of age. The sample consisted of 23 children–mother dyads. The sample recruitment strategy emphasized testing both typical and fussy/difficult infants at 9 months of age. Children were categorized into low and high behavioral problem groups at 54 months of age. The children in the high behavioral problem group were more likely at 9 months to have been temperamentally difficult, to have been classified as regulatory disordered, and to have displayed respiratory sinus arrhythmia (RSA) regulation difficulties. These children also were more likely to come from families described as less cohesive and providing less focus on active/recreational activities when the children were 54 months old. A logistic regression analysis, including only the 9‐month infant measures (i.e., difficultness, regulatory disorders classification, and RSA regulation), resulted in a significant model with 100.0% accurate classification into high or low behavioral problem groups. Data suggest that infant measures of behavioral and physiological state regulation may be early indicators of child behavior problems, especially internalizing problems.     

Learning from others in 9‐18‐month‐old infants

The use of an adult as a resource for help and instruction in a problem solving situation was examined in 9, 14, and 18‐month‐old infants. Infants were placed in various situations ranging from a simple means‐end task where a toy was placed beyond infants' prehensile space on a mat, to instances where an attractive toy was placed inside closed transparent boxes that were more or less difficult for the child to open. The experimenter gave hints and modelled the solution each time the infant made a request (pointing, reaching, or showing a box to the experimenter), or if the infant was unable to solve the problem. Infants' success on the problems, sensitivity to the experimenter's modelling, and communicative gestures (requests, co‐occurrence of looking behaviour and requests) were analysed. Results show that older infants had better success in solving problems although they exhibited difficulties in solving the simple means‐end task compared to the younger infants. Moreover, 14‐ and 18‐month‐olds were sensitive to the experimenter's modelling and used her demonstration cues to solve problems. By contrast, 9‐month‐olds did not show such sensitivity. Finally, 9‐month‐old infants displayed significantly fewer communicative gestures toward the adult compared to the other age groups, although in general, all infants tended to increase their frequency of requests as a function of problem difficulty. These observations support the idea that during the first half of the second year infants develop a new collaborative stance toward others. The stance is interpreted as foundational to teaching and instruction, two mechanisms of social learning that are sometime considered as specifically human.

Imitation from television by 24‐ and 30‐month‐olds

Infants’ imitation of complex actions was examined in three experiments with 24‐ and 30‐month‐olds. In all experiments, an adult modeled a series of actions with novel stimuli and the infant's reproduction of those actions was assessed either immediately or after a 24‐hour delay. Some infants watched the demonstration live, while other infants watched the same demonstration on television from a pre‐recorded videotape. Both 24‐ and 30‐month‐olds imitated actions that had been modeled on television; however, their performance was consistently inferior to that of infants of the same age who watched the demonstration live.     

The attentional ‘zoom‐lens’ in 8‐month‐old infants

The spatial attention mechanisms of orienting and zooming cooperate to properly select visual information from the environment and plan eye movements accordingly. Despite the fact that orienting ability has been extensively studied in infancy, the zooming mechanism – namely, the ability to distribute the attentional resources to a small or large portion of the visual field – has never been tested before. The aim of the present study was to evaluate the attentional zooming abilities of 8‐month‐old infants. An eye‐tracker device was employed to measure the saccadic latencies (SLs) at the onset of a visual target displayed at two eccentricities. The size of the more eccentric target was adjusted in order to counteract the effect of cortical magnification. Before the target display, attentional resources were automatically focused (zoom‐in) or spread out (zoom‐out) by using a small or large cue, respectively. Two different cue–target intervals were also employed to measure the time course of this attentional mechanism. The results showed that infants' SLs varied as a function of the cue size. Moreover, a clear time course emerged, demonstrating that infants can rapidly adjust the attentional focus size during a pre‐saccadic temporal window. These findings could serve as an early marker for neurodevelopmental disorders associated with attentional zooming dysfunction such as autism and dyslexia.
