Infants Anticipate Others' Social Preferences

In the current eye‐tracking study, we explored whether 12‐month‐old infants can predict others' social preferences. We showed infants scenes in which two characters alternately helped or hindered an agent in his goal of climbing a hill. In a control condition, the two characters moved up and down the hill in identical ways to the helper and hinderer but did not make contact with the agent; thus, they did not cause him to reach or not reach his goal. Following six alternating familiarization trials of helping and hindering interactions (help–hinder condition) or up and down interactions (up–down condition), infants were shown one test trial in which they could visually anticipate the agent approaching one of the two characters. As predicted, infants in the help–hinder condition made significantly more visual anticipations toward the helping than hindering character, suggesting that they predicted the agent to approach the helping character. In contrast, infants revealed no difference in visual anticipations between the up and down characters. The up–down condition served to control for low‐level perceptual explanations of the results for the help–hinder condition. Thus, together the results reveal that 12‐month‐old infants make predictions about others' behaviour and social preferences from a third‐party perspective.

How do 8‐month‐old infants recognize causality in object motion and that in human action?1

Abstract: In Experiment 1, 8‐month‐old infants were first habituated to the event in which a moving object collided with another behind an occluder, then they were shown the two test events with no occluder: the contact event, in which the two objects actually collided, and the non‐contact event, in which the second object started to move without contact with the first. The infants looked at both events for an equal amount of time. In Experiment 2, in which the first object was a human actor, however, infants looked at the non‐contact event reliably longer than the contact event. In Experiment 3, in which both objects were human actors stood face‐to‐back, infants looked at the non‐contact event longer, whereas in Experiment 4, in which human actors faced toward each other, infants looked at both events equally. In Experiment 5, in which the first actor told the second to go, 10‐month‐old infants looked at both events for an equal amount of time. These results suggest that 8‐ and 10‐month‐old infants appreciate different causal principles between objects and humans, and that, in doing this, they may acknowledge the possibility of communication between humans.     

When and why is helping others good for well‐being? The role of belief in reciprocity and conformity to society's expectations

This research investigates the relation between informal help and subjective well‐being and its underlying mechanisms using a cross‐national perspective. We focus on two potential mechanisms derived from the self‐determination theory and conformity to the social norms literature. From the standpoint of self‐determination theory, helping others is good for well‐being if it is intrinsically motivated, rather than driven by the expectation of reciprocity. On the other hand, from the perspective of the conformity literature, helping others is associated with a higher well‐being when it is linked to the benefits of social conformity, such as social approval. We tested these hypotheses using the data from a total of 23 countries. The results provided support for both mechanisms. First, we found that the lower individuals' beliefs in reciprocity are, the stronger is the positive effect of self‐reported helping behavior on their well‐being. Second, helping behavior was more strongly related to life satisfaction in countries where providing help represents a strong social norm (measured with two different cultural indicators). We conclude that both individual‐ and culture‐level mechanisms account for the relation between prosocial behavior and well‐being. Copyright © 2015 John Wiley & Sons, Ltd.     

Illusory contour figures are perceived as occluding surfaces by 8‐month‐old infants

Infants have been demonstrated to be able to perceive illusory contours in Kanizsa figures. This study tested whether they also perceive these illusory figures as having the properties of real objects, such as depth and capability of occluding other objects. Eight‐ and five‐month‐old infants were presented with scenes that included a Kanizsa square and further depth cues provided by the deletion and accretion pattern of a moving duck. The 8‐month‐old infants looked significantly longer at the scene when the two types of occlusion cues were inconsistent than when they were consistent with each other, which provides evidence that they interpreted the Kanizsa square as a depth cue. In contrast, 5‐month‐olds did not show this difference. This finding demonstrates that 8‐month‐olds perceive the figure formed by the illusory contours as having properties of a real object that can act as an occluder.     

Stated goals and their influence on helping behavior toward ingroups and outgroups

When seeking to motivate individuals to help, helping behavior may be framed in terms of power‐oriented, results focused, goals or value‐oriented, ideologically based, goals. In two studies, participants were presented with a call for assistance benefitting an ingroup or an outgroup. The stated goal associated with helping behavior was power‐oriented or value‐oriented. Participants showed more willingness to help on behalf of an outgroup when they believed the charitable organization had value‐oriented goals and more willingness to help on behalf of their ingroup when they believed the charitable organization had power‐oriented goals. The results suggest that organizations should consider the relationship between who will benefit and who is providing assistance to maximize the likelihood that assistance will be provided.     

Ten-month-olds' selective use of visual dimensions in category learning

There is now general consensus that infants can use several different visual properties as the basis for categorization. Nonetheless, little is known about when and whether infants can be guided by contextual information to select the relevant properties from amongst those available to them. We show here that by 10 months of age infants can be biased, through observational learning, to use one or the other of two object properties for classification. Two groups of infants watched an actress classifying objects by either shape (the Shape group) or surface pattern (the Pattern group). When subsequently presented with two test trials which contradicted either one or the other of the classification rules, infants in the two groups looked longer to the classification event that was incompatible with the rule that group had been familiarized to. These results are discussed with reference to the development of selective feature processing in infancy.     

How infants process addition and subtraction events

Three experiments are described that assess 5‐month‐old infants’ processing of addition and subtraction events similar to those reported by Wynn (1992a ). In Experiment 1, prior to each test trial, one group of infants was shown an addition event (1 + 1) while another group was shown a subtraction event (2 ? 1). On test trials, all infants were shown outcomes of 0, 1, 2 and 3. The results seemed to require one of two dual‐process models. One such model assumed that the infants could add and subtract but also had a tendency to look longer when more items were on the stage. The other model assumed that infants had a preference for familiarity along with the tendency to look longer when more items were on the stage. Experiments 2 and 3 examined the assumptions made by these two models. In Experiment 2, infants were given only the test trials they had received in Experiment 1. Thus, no addition and subtraction or familiarity was involved. In Experiment 3 infants were familiarized to either one or two items prior to each test trial, but experienced no actual addition or subtraction. The results of these two experiments support the familiarity plus more items to look at model more than the addition and subtraction plus more items to look at model. Taken together, these three experiments shed doubt on Wynn’s (1992a ) assertion that 5‐month‐old infants can add and subtract. Instead they indicate the importance of familiarity preferences and the fact that one should be cautious before assuming that young infants have sophisticated numerical abilities.     

Blurring the Dichotomy of Good and Evil: The Idiosyncratic Helping Strategies Associated with Unmitigated‐Agentic and Unmitigated‐Communal Personalities

We theorized that unmitigated‐agentic personality constructs (UAPs)—prioritizing 'getting ahead’ over 'getting along’—and unmitigated‐communal personality constructs (UCPs)—prioritizing getting along over getting ahead—are associated with distinct affect‐regulatory helping strategies. In Study 1 (N = 179), UAPs, on average, related to greater negative‐affect versus positive‐affect induction helping tactics. In two experiments, UAPs, on average, related to a greater likelihood of selecting anger‐inducing versus love‐inducing or sadness‐inducing songs to help a target overcome a breakup (Study 2; N = 313) and greater selection of anger‐inducing and hubris‐inducing messages versus authentic‐pride‐inducing and love‐inducing messages to help a teammate struggling in a game (Study 3; N = 246). UCPs manifested the opposite patterns. Generally, these associations corresponded with helping‐strategy utility beliefs and were robust to moderators of helping target (self or other; Study 2) or altruistic versus selfish motives (Study 3). Study 4 (N = 205) provided some evidence of ecological validity in contexts of recalled everyday helping. Associations between personality constructs and relative helping strategies were about moderate in size (rs ~ .20) across these four studies. Findings suggest that UAPs are associated with helping strategies believed to promote ‘contemptuous’ self‐enhancement relative to ‘innocuous’ self‐enhancement and self‐transcendence, and vice versa for UCPs. © 2019 European Association of Personality Psychology     

In‐group bias in children's intention to help can be overpowered by inducing empathy

An experimental vignette study was conducted among children (8–13 years) to examine whether inducing empathic understanding is an effective intervention to overpower peer group boundaries in children's helping. Children were induced or not induced to empathize with the recipient of help, who was or was not part of their (imagined) group of friends. Results showed that children intended to help in‐group peers more compared to outgroup peers when empathic understanding was not induced. However, when empathy was induced, they intended to help friends and non‐friends equally. Inducing empathic understanding was effective independent of the recipient's level of need, and children's advanced social perspective‐taking ability. Encouraging children to imagine how a recipient of help feels might thus be a useful strategy to prevent peer group‐based biases in children's helping behaviour.     

Probing the depth of infants’ theory of mind: disunity in performance across paradigms

There is currently a hot debate in the literature regarding whether or not infants have a true theory of mind (ToM) understanding. According to the mentalistic view, infants possess the same false belief understanding that older children have but their competence is masked by task demands. On the other hand, others have proposed that preverbal infants are incapable of mental state attribution and simply respond to superficial features of the events in spontaneous‐responses tasks. In the current study, we aimed to clarify the nature of infants’ performance in tasks designed to assess implicit theory of mind (ToM) by adopting a within‐subject design that involved testing 18‐month‐old infants on two batteries of tasks measuring the same four ToM constructs (intention, desire, true belief, and false belief). One battery included tasks based on the violation‐of‐ expectation (VOE) procedure, whereas the other set of tasks was based on the interactive, helping procedure. Replication of the original findings varied across tasks, due to methodological changes and the use of a within‐subject design. Convergent validity was examined by comparing performance on VOE and interactive tasks that are considered to be measures of the same theory of mind concept. The results revealed no significant relations between performance on the pairs of tasks for any of the four ToM constructs measured. This pattern of results is discussed in terms of current conflicting accounts of infants’ performance on implicit ToM tasks.

Object individuation and labelling in 6-month-old infants

The ability to determine how many objects are involved in physical events is fundamental for reasoning about the world that surrounds us. Previous studies suggest that infants can fail to individuate objects in ambiguous occlusion events until their first birthday and that learning words for the objects may play a crucial role in the development of this ability. The present eye-tracking study tested whether the classical object individuation experiments underestimate young infants’ ability to individuate objects and the role word learning plays in this process. Three groups of 6-month-old infants (N = 72) saw two opaque boxes side by side on the eye-tracker screen so that the content of the boxes was not visible. During a familiarization phase, two visually identical objects emerged sequentially from one box and two visually different objects from the other box. For one group of infants the familiarization was silent (Visual Only condition). For a second group of infants the objects were accompanied with nonsense words so that objects’ shape and linguistic labels indicated the same number of objects in the two boxes (Visual & Language condition). For the third group of infants, objects’ shape and linguistic labels were in conflict (Visual vs. Language condition). Following the familiarization, it was revealed that both boxes contained the same number of objects (e.g. one or two). In the Visual Only condition, infants looked longer to the box with incorrect number of objects at test, showing that they could individuate objects using visual cues alone. In the Visual & Language condition infants showed the same looking pattern. However, in the Visual vs Language condition infants looked longer to the box with incorrect number of objects according to linguistic labels. The results show that infants can individuate objects in a complex object individuation paradigm considerably earlier than previously thought and that linguistic cues enforce their own preference in object individuation. The results are consistent with the idea that when language and visual information are in conflict, language can exert an influence on how young infants reason about the visual world.     

From understanding others' needs to prosocial action: Motor and social abilities promote infants' helping

In the present study, we test the main hypothesis that infants' understanding of others' needs translates into helping behavior, when critical motor and social competencies have emerged, early in the second year. We assessed the understanding of others' needs in an eye‐tracking paradigm and the helping behavior of 10‐ (n = 41) and 16‐month‐olds (n = 37). Furthermore, we assessed the motor and social abilities of 16‐month‐olds. Critically, while infants understood others' needs already at 10 months, fine motor and social interaction skills moderated the link between infants' prosocial understanding and helping behavior at 16 months. This provides first evidence that infants' helping behavior relates to their understanding of others' needs. Furthermore, we found that fine motor, gross motor, and social interaction skills predicted early helping behavior by themselves. These findings highlight that the emergence of infants' helping behavior is the result of a developmental system that includes infants' understanding of others' needs and also their motor and social competencies. The link between infants' understanding of others' needs and their early helpful actions provide further support for the prosocial nature of early helping behavior.     

Self‐Esteem and Justice Orientation as Moderators for the Effects of Individual‐Targeted and Group‐Targeted Justice

Drawing on the self‐interest and moral virtues perspectives of justice, we examine how self‐esteem and justice orientation as individual difference factors moderate the effects of individual‐targeted and group‐targeted justice on helping behaviors and intention to leave. A scenario‐based study was conducted using a total sample of 624 Japanese undergraduate students. The results highlighted the difference between the moderating roles of self‐esteem and justice orientation. Self‐esteem moderated the effect of individual‐targeted procedural justice on intention to leave such that the effect was stronger when self‐esteem was high. In contrast, justice orientation mainly moderated the effects of group‐targeted procedural and distributive justice on helping behaviors such that the effects were weaker when justice orientation was high. Implications of our findings and future research directions are discussed.     

Older but not younger infants associate own‐race faces with happy music and other‐race faces with sad music

We used a novel intermodal association task to examine whether infants associate own‐ and other‐race faces with music of different emotional valences. Three‐ to 9‐month‐olds saw a series of neutral own‐ or other‐race faces paired with happy or sad musical excerpts. Three‐ to 6‐month‐olds did not show any specific association between face race and music. At 9 months, however, infants looked longer at own‐race faces paired with happy music than at own‐race faces paired with sad music. Nine‐month‐olds also looked longer at other‐race faces paired with sad music than at other‐race faces paired with happy music. These results indicate that infants with nearly exclusive own‐race face experience develop associations between face race and music emotional valence in the first year of life. The potential implications of such associations for developing racial biases in early childhood are discussed.     

Helping others or helping oneself? An episodic examination of the behavioral consequences of helping at work

Scholars have paid an increasing amount of attention to organizational citizenship behaviors (OCBs), with a particular emphasis on helping others at work. In addition, recent empirical work has focused on how OCB is an intraindividual phenomenon, such that employees vary daily in the extent to which they help others. However, one limitation of this research has been an overemphasis on well‐being consequences associated with daily helping (e.g., changes in affect and mental depletion) and far less attention on behavioral outcomes. In this study, we develop a self‐regulatory framework that articulates how helping others at work is a depleting experience that can lead to a reduction in subsequent acts of helping others, and an increase in behaviors aimed at helping oneself (i.e., engaging in political acts). We further theorize how two individual differences—prevention focus and political skill—serve as cross‐level moderators of these relations. In an experience sampling study of 91 full‐time employees across 10 consecutive workdays, our results illustrate that helping is a depleting act that makes individuals more likely to engage in self‐serving acts and less likely to help others. Moreover, the relation of helping acts with depletion is strengthened for employees who have higher levels of prevention focus.     

Infants’ coding of location in continuous space

The ability to code location in continuous space is fundamental to spatial behavior. Existing evidence indicates a robust ability for such coding by 12 months, but systematic evidence on earlier origins is lacking. A series of studies investigated 5-month-olds’ ability to code the location of an object hidden in a sandbox, using a looking-time paradigm. In Experiment 1, after familiarization with a hiding-and-finding sequence at one location, infants looked longer at an object being disclosed from a location 12 inches (30 cm) away than at an object emerging from the hiding location, showing they were able to code location in continuous space. In Experiment 2, infants reacted with greater looking when objects emerged from locations 8 inches (20 cm) away from the hiding location, showing that location coding was more finely grained than could be inferred based on the first study. In Experiment 3, infants were familiarized with an object shown in hiding-and-finding sequences at two different locations. Infants looked longer at objects emerging 12 inches (30 cm) away from the most recent hiding location than to emergence from the other location, showing that infants could code location even when events had previously occurred at each location. In Experiment 4, after familiarization with two objects with different shapes, colors, and sounding characteristics, shown in hiding-and-finding sequences in two locations, infants reacted to location violations as they had in Experiment 3. However, they did not react to object violations, that is, events in which the wrong object emerged from a hiding location. Experiment 5 also found no effect of object violation, even when the infants initially saw the two objects side by side. Spatiotemporal characteristics may play a more central role in early object individuation than they do later, although further study is required.     

Affective matching of odors and facial expressions in infants: shifting patterns between 3 and 7 months

Recognition of emotional facial expressions is a crucial skill for adaptive behavior. Past research suggests that at 5 to 7 months of age, infants look longer to an unfamiliar dynamic angry/happy face which emotionally matches a vocal expression. This suggests that they can match stimulations of distinct modalities on their emotional content. In the present study, olfaction–vision matching abilities were assessed across different age groups (3, 5 and 7 months) using dynamic expressive faces (happy vs. disgusted) and distinct hedonic odor contexts (pleasant, unpleasant and control) in a visual‐preference paradigm. At all ages the infants were biased toward the disgust faces. This visual bias reversed into a bias for smiling faces in the context of the pleasant odor context in the 3‐month‐old infants. In infants aged 5 and 7 months, no effect of the odor context appeared in the present conditions. This study highlights the role of the olfactory context in the modulation of visual behavior toward expressive faces in infants. The influence of olfaction took the form of a contingency effect in 3‐month‐old infants, but later evolved to vanish or to take another form that could not be evidenced in the present study.     

The roots of human altruism

Human infants as young as 14 to 18 months of age help others attain their goals, for example, by helping them to fetch out‐of‐reach objects or opening cabinets for them. They do this irrespective of any reward from adults (indeed external rewards undermine the tendency), and very likely with no concern for such things as reciprocation and reputation, which serve to maintain altruism in older children and adults. Humans' nearest primate relatives, chimpanzees, also help others instrumentally without concrete rewards. These results suggest that human infants are naturally altruistic, and as ontogeny proceeds and they must deal more independently with a wider range of social contexts, socialization and feedback from social interactions with others become important mediators of these initial altruistic tendencies.     

Infants can infer the presence of hidden objects from referential gaze information

Infants' apparent failure in gaze‐following tasks is often interpreted as a sign of lack of understanding the referential nature of looking. In the present study, 8‐ and 12‐month‐old infants followed the gaze of a model to one of two locations hidden from their view by occluders. When the occluders were removed, an object was revealed either at the location where the model had looked or at the other side. Infants at both ages looked longer at the empty location when it had been indicated by the model's looking behaviour, and this effect held up even when their first look after gaze following was discounted. This result demonstrates that even young infants hold referential expectations when they follow others' gaze and infer the location of hidden objects accordingly.     

Paying it forward: how helping others can reduce the psychological threat of receiving help

This paper shows that receiving help could be psychologically harmful for recipients, and passing on help to others after receiving help (“helping forward”) is a good strategy to improve and restore help recipients' self‐competence. Participants (N = 87) received autonomy‐ or dependency‐oriented help and anticipated helping forward or not. Compared to receiving autonomy‐oriented help, receiving dependency‐oriented help negatively affected participants' self‐competence and their evaluation of the helper. Anticipation of future helping increased the liking for and evaluation of the helper. After paying help forward, participants felt more self‐competent than before helping, and this effect was more pronounced among former recipients of dependency‐oriented help. These results show that helping forward can negate the psychological threat associated with receiving help.
