Accuracy and differentiation in social prediction: A developmental perspective1

Two studies examined the accuracy and differentiation of 4–5-yearolds‘, 8–9-year-olds’, and undergraduates' predictions of the preferences of peers and nonpeers. In Study 1 each subject was presented with separate arrays of snacks, meals, and activities depicted on cards and were asked to select their own preferences and the preferences of peers and nonpeers (“grown-ups” for the children, and “4- to 5-year-olds” for the undergraduates). In Study 2 each subject selected his or her own preference, the preference of peers, and the preferences of both older nonpeers (“grown-ups”) and younger nonpeers (“2-year-olds”). For all age groups, including 4–5-year-olds: (1) the preference predictions differentiated peers from nonpeers, as well as older nonpeers from younger nonpeers; (2) it was very rare for a subject to select his or her own preferences for the preference predictions of both peers and nonpeers. There were no consistent developmental differences either in the tendency to select one's own preferences when predicting the preferences of others or in the tendency to differentiate predictions for peers and nonpeers. In contrast, there was a clear developmental increase in predictive accuracy, with 4–5-year-olds being relatively inaccurate in predicting the preferences of nonpeers. The inadequacy of constructs such as “assumed similarity” and “egocentrism” as explanations for the general accuracy in predicting peers' preferences and the 4–5-year-olds' inaccuracy in predicting nonpeers' preferences is discussed. Possible alternative variables underlying developmental increases in judgmental accuracy, such as “social reference,”“self reference,” and “social category knowledge,” are then proposed.     

Preschool Children's Understanding of Conflicting Desires

This study examines the conditions under which 3-year-olds can use the desires of others to predict others' behavior. In Study 1, children were highly successful in predicting the actions of an agent based on that agent's desires when they were explicitly told about the agent's desires, even when the agent's desires were strongly different from the children's own. Study 2 showed that 3-year-olds could also predict the actions of an agent when they had to infer the agent's desires from the previous good and bad experiences of the agent and from information about the agent's general behavioral preferences. Studies 3 and 4 demonstrated that children had difficulty predicting an agent's behavior when they both had to infer the desire of the agent and this desire conflicted with their own desires. These results suggest that preschoolers' desire reasoning is sophisticated but also may be influenced by the processing demands of the task.     

Children’s Understanding and Use of Four Dimensions of Social Status

ABSTRACT

Beginning early in life, children are exposed to people who differ in social status. In five studies, we investigate whether 3- to 6-year-old children recognize different dimensions of status (i.e., wealth, physical dominance, decision-making power, and prestige) and use these dimensions to inform their social judgments (preferences and resource allocation). Across studies, we found that by age 3, children identify high-status people as in-charge. Further, while 3-6-year-olds favor higher status individuals over lower status individuals on a preference measure, 5-6-year-olds allocate a resource to a lower status individual over a higher status individual and 3-4-year-olds are at chance in their allocation. We observed minimal differences across dimensions of status in these studies. Taken together, across five pre-registered studies, we demonstrated that children identify and use social status distinctions to inform their social judgments across a variety of different dimensions.     

Young children infer causal strength from probabilities and interventions

We examine the interaction of two cues that children use to make judgments about cause-effect relations: probabilities and interventions. Children were shown a "detector" that lit up and played music when a block was placed on its surface. We varied the probabilistic effectiveness of the block, as well as whether the experimenter or the child was performing the interventions. In Experiment 1, we found that children can use probabilistic evidence to make inferences about causal strength. However, when the results of their own interventions are in conflict with the overall frequencies, preschoolers favor the results of their own interventions. In Experiment 2, children used probabilistic evidence to infer a hidden causal mechanism. Though they again gave preference to their own interventions, they did not do so when their interventions were explicitly confounded by an alternative cause.     

Anti-equality: Social comparison in young children

Young children dislike getting less than others, which might suggest a general preference for equal outcomes. However, young children are typically not averse to others receiving less than themselves. These results are consistent with two alternatives: young children might not have any preferences about others receiving less than themselves, or they might have preferences for others receiving less than themselves. We test these alternatives with 5- to 10-year-old children. We replicate previous findings that children will take a cost to avoid being at a relative disadvantage, but also find that 5- and 6-year-olds will spitefully take a cost to ensure that another’s welfare falls below their own. This result suggests that the development of fairness includes overcoming an initial social comparison preference for others to get less relative to oneself.     

Sensitivity to the Sampling Process Emerges From the Principle of Efficiency

Humans can seamlessly infer other people's preferences, based on what they do. Broadly, two types of accounts have been proposed to explain different aspects of this ability. The first account focuses on spatial information: Agents' efficient navigation in space reveals what they like. The second account focuses on statistical information: Uncommon choices reveal stronger preferences. Together, these two lines of research suggest that we have two distinct capacities for inferring preferences. Here we propose that this is not the case, and that spatial‐based and statistical‐based preference inferences can be explained by the assumption that agents are efficient alone. We show that people's sensitivity to spatial and statistical information when they infer preferences is best predicted by a computational model of the principle of efficiency, and that this model outperforms dual‐system models, even when the latter are fit to participant judgments. Our results suggest that, as adults, a unified understanding of agency under the principle of efficiency underlies our ability to infer preferences.     

Eye as a key element of conspecific image eliciting lateralized response in fish

Visual lateralization in different aspects of social behaviour has been found for numerous species of vertebrates ranging from fish to mammals. For inspection of a shoal mate, many fishes show a left eye–right hemisphere preference. Here, we tested the hypothesis that in fish, there is a key cue in the conspecific appearance, which elicits lateralized response to the whole image of the conspecific. In a series of eight experiments, we explored eye preferences in cryptic-coloured Amur sleeper, Perccottus glenii, fry. Fish displayed left-eye preferences at the population level for inspection of a group of conspecifics, their own mirror image, and a motionless flat model of a conspecific. In contrast, no population bias was found for scrutinizing an empty environment or a moving cylinder. When fry were showed a model of a conspecific in a lateral view with the eye displaced from the head to the tail, they again showed a significant preference for left-eye use. On the other hand, ‘eyeless’ conspecific model elicited no lateralized viewing in fry. Finally, the left-eye preference was revealed for scrutiny of the image of a conspecific eye alone. We argue that in Amur sleeper fry, eye is the element of the conspecific image, which can serve as a ‘key’ for the initiation of lateralized social response. This key element may serve as a trigger for the rapid recognition of conspecifics in the left eye–right hemisphere system. Possible causes and advantages of lateralized perception of social stimuli and their key elements are discussed in the context of current theories of brain lateralization.     

The Development of Social Exclusion Detection in Early Childhood: Awareness of Social Exclusion Does Not Always Align with Social Preferences

ABSTRACT

Starting in the preschool years, children show socially exclusive behaviors, such as intentionally leaving out another child from a ball game. Prior research investigating social exclusion understanding in preschoolers primarily used interview methods and it is clear that the verbal and cognitive skills necessary to identify and reason about social exclusion become more sophisticated with age. Yet it is unknown how children’s ability to identify social exclusion relates to their own behavior, such as their social preference for socially inclusive or exclusive individuals. Further, whether such social preferences remain stable or change across development is an open question. Thus, the current study investigated whether the ability to identify social exclusion develops in tandem with social preference behavior by assessing 3- to 6-year-old children’s (N = 256) identification of social exclusion and preferences between socially exclusive and inclusive agents. Five- to six-year-old children correctly identified social exclusion and preferred inclusive agents over exclusive agents across two experiments. Three- to four-year-old children could correctly identify social exclusion, but did not show evidence of a preference for inclusive agents over exclusive agents. Children were also able to detect implicit, nonverbalized social exclusion equally well as explicit, verbalized social exclusion across development. These findings suggest that young children’s social preferences are not wholly dictated by their ability to identify socially exclusive agents. This divergent pattern of social preference from identification has implications for interpreting social preference behavior in young children.     

When Choices Are Not Personal: The Effect of Statistical and Social Cues on Children's Inferences About the Scope of Preferences

Individual choices are commonly taken to manifest personal preferences. The present study investigated whether social and statistical cues influence young children's inferences about the generalizability of preferences. Preschoolers were exposed to either 1 or 2 demonstrators’ selections of objects. The selected objects constituted 18%, 50%, or 100% of all available objects. We found that children took a single demonstrator's choices as indicative only of his or her personal preference. However, when 2 demonstrators made the same selection, then children inferred that it generalized to other agents of the same kind as the original demonstrator's, but not to agents of a different kind. Lastly, only when both demonstrators blatantly violated random selection (i.e., in the 18% condition) did children generalize the preference even to an agent of a different kind. Thus, from a young age, social and statistical cues inform children's naïve sociology.     

Eye‐tracking Social Preferences

We hypothesize that if people are motivated by a particular social preference, then choosing in accordance with this preference will lead to an identifiable pattern of eye movements. We track eye movements while subjects make choices in simple three‐person distribution experiments. We characterize each choice in terms of three different types of social preferences: efficiency, maxi‐min, and envy. For the characterization, we use either the choice data or the eye movement data. The evidence indicates that distributional choices are broadly consistent with the choice rule implied by eye movements. In other words, what subjects appear to be interested in when you look at their choices corresponds to what they appear to be interested in when you look at their eye movements. This correspondence lends credibility to the behavioral relevance of social preferences models. Copyright © 2015 John Wiley & Sons, Ltd.     

Social discounting of pain

Impatience can be formalized as a delay discount rate, describing how the subjective value of reward decreases as it is delayed. By analogy, selfishness can be formalized as a social discount rate, representing how the subjective value of rewarding another person decreases with increasing social distance. Delay and social discount rates for reward are correlated across individuals. However no previous work has examined whether this relationship also holds for aversive outcomes. Neither has previous work described a functional form for social discounting of pain in humans. This is a pertinent question, since preferences over aversive outcomes formally diverge from those for reward. We addressed this issue in an experiment in which healthy adult participants (N = 67) chose the timing and intensity of hypothetical pain for themselves and others. In keeping with previous studies, participants showed a strong preference for immediate over delayed pain. Participants showed greater concern for pain in close others than for their own pain, though this hyperaltruism was steeply discounted with increasing social distance. Impatience for pain and social discounting of pain were weakly correlated across individuals. Our results extend a link between impatience and selfishness to the aversive domain.     

Variable preferences for sexual dimorphism in stature (SDS): Further evidence for an adjustment in relation to own height

In contemporary Western populations, some physical characteristics are sexually dimorphic, and it is known that these traits also affect human mate preferences. Height is one such characteristic, and evidence suggests that females prefer taller over shorter males, indeed, taller males have been found to have greater reproductive success. However, relative height is also important with ‘Sexual Dimorphism in Stature’ (SDS) calculated as male height/female height. Pawlowski (2003) showed that people adjust their preferences for SDS in relation to their own height in order to increase their potential pool of partners. The aim of the present study was to replicate Pawlowski’s study on a larger sample of participants, and to investigate the universality of the reported preference adjustment within European societies. We present data of 1102 men and women from three countries (Germany, Austria, and the UK) that confirm Pawlowski’s original data on a Polish sample. Moreover, the mechanism of an adjustment of SDS preferences in relation to own height was found in all three countries, suggesting that height dependent partner preference is a genuine feature in Western societies.     

Social learning of food types in zebra finches (<Emphasis Type="Italic">Taenopygia guttata</Emphasis>) is directed by demonstrator sex and feeding activity

In this study we examined how social learning of feeding preferences by zebra finches was affected by the identity of different demonstrators. We presented adult zebra finches with two demonstrators, one male and one female, that exhibited different food choices, and we recorded their subsequent preference when given a choice between the two food types. Previously it was found that young zebra finches' patterns of social learning are affected by the sex of the individual demonstrating a feeding behaviour. This result could be explained by the lack of exposure these animals had to the opposite sex, or by their mating status. Therefore, we investigated the social learning preferences of adult mated zebra finches. We found the same pattern of directed social learning of a different type of feeding behaviour (food colour): female zebra finches preferred the colour of food eaten by male demonstrators, whereas male zebra finches showed little evidence of any preference for the colour of food eaten by female demonstrators. Furthermore, we found that female observers' preferences were biased by demonstrators' relative feeding activity: the female demonstrator was only ever preferred if it ate less than its male counterpart.

Children’s reasoning about norms and traits as motives for behavior

Two important sources of information for social judgments are personality dispositions (traits) and social norms. Existing research suggests that young children do not find traits salient. To what extent might they rely on a different source of information? Two experiments explored how information about preferences (what someone likes) and rules (what is allowed or forbidden) affected social judgments. Five-year-olds predicted people’s future behavior would be consistent with rules, but appeared insensitive to information about preferences. Preferences were better predictors than rules for 8-year-olds. Older children and adults consistently judged that actors would want to, and be happy to, satisfy preferences rather than rules. Younger children were more likely to use rules to infer people’s psychological states. Results are consistent with the hypothesis that deontic relations, such as rules and norms play a central role in young children’s social cognition, with ideas of individual psychological dispositions emerging in middle childhood.     

Development of infant prehension handedness: A longitudinal analysis during the 6- to 14-month age period

Handedness is a developmental phenomenon that becomes distinctively identifiable during infancy. Although infant hand-use preferences sometimes have been reported as unstable, other evidence demonstrates that infant hand-use preference for apprehending objects can be reliably assessed during the second half of the infant's first year of life. The current study provides further insight into the stability of prehension preferences. We modeled individual and group level patterns of prehension handedness during the period from 6 to 14 months of age. We examined the developmental trajectories for prehension handedness in relation to the sampling rate at which preferences are assessed. The results revealed interesting developmental changes in prehension handedness that can only be identified when using monthly sampling intervals. We conclude that using non-linear multilevel models of infant handedness with monthly sampling intervals permit us to accurately capture the developmental changes in manual skills that occur during this period of infancy.     

Competitiveness across the life span: the feisty fifties

Existing theories on life span changes in confidence or motivation suggest that individuals' preferences to enter competitive situations should gradually decline with age. We examined competitive preferences in a field experiment using real financial stakes in 25- to 75-year-olds (N = 543). The critical dependent variable was whether participants chose to perform a simple mental arithmetic task either under a piece-rate payment schedule (i.e., $.25 per solved item) or a competitive payment schedule ($.50 per solved item if the overall score is better than that of a randomly selected opponent, $0 otherwise). Results revealed that competitive preferences increased across the life span until they peaked around age 50, and dropped thereafter. We also found that throughout, men had a substantially larger preference for competing than women-extending previous findings on college-aged participants. The age/gender differences in preferences were neither accounted for by actual differences in performance nor individuals' subjective confidence. This first systematic attempt to characterize age differences in competitive behavior suggests that a simple decline conception of competitiveness needs to be reconsidered.     

The interplay between perceived busyness and power distance belief on subjective social status: Consequences for consumer preferences for material versus experiential purchases

The perception of a busy life as an indicator of self-worth varies among individuals. Postulating that this perceptual difference can be attributed to one's attitude toward social stratification, the current research examines the interplay between perceived busyness and power distance belief (PDB). We propose that perceived busyness dictates a consumer's subjective social status under low PDB but not under high PDB. Furthermore, the interaction between perceived busyness and PDB determines an individual's relative preference for purchase types: material versus experiential purchases. Study 1 verifies that consumers' perceived busyness has a positive effect on their evaluation of their social status when they have low PDB, whereas this effect disappears when they have high PDB. Study 2 tests the asymmetric effect of perceived busyness and PDB on preference for purchase types, and Study 3 further provides evidence for the mediating role of subjective social status.     

Low- and high-testosterone individuals exhibit decreased aversion to economic risk

Testosterone is positively associated with risk-taking behavior in social domains (e.g., crime, physical aggression). However, the scant research linking testosterone to economic risk preferences presents inconsistent findings. We examined the relationship between endogenous testosterone and individuals' economic preferences (i.e., risk preference, ambiguity preference, and loss aversion) in a large sample (N = 298) of men and women. We found that endogenous testosterone levels have a significant U-shaped association with individuals' risk and ambiguity preferences, but not loss aversion. Specifically, individuals with low or high levels of testosterone (more than 1.5 SD from the mean for their gender) were risk and ambiguity neutral, whereas individuals with intermediate levels of testosterone were risk and ambiguity averse. This relationship was highly similar in men and women. In contrast to received wisdom regarding testosterone and risk, the present data provide the first robust evidence for a nonlinear association between economic preferences and levels of endogenous testosterone.     

Individual differences in preference for risky behaviors during courtship

Engaging in risky behaviors is a sexual signalling strategy that men use to procure mates. The present study investigates men’s preferences for engaging in risky behaviors (along with women’s preferences for their male partner’s risky behavior) within dating couples. We investigated associations between relationship length, self-perceived attractiveness, sociosexuality orientation, and preference for risky behaviors in a sample of 256 couples. Results indicated that men had stronger preferences for risky behaviors than their partner’s ideal preference. Furthermore, relationship length was associated with a decline in women’s preference for their partner’s risk-taking, but not men’s preference for their own risk-taking. Self-perceived attractiveness was negatively associated with risk preference, and sociosexuality orientation was not directly related to risk preference. Female preferences for less intense male risky behaviors could reflect the need of paternal investment which is required for offspring care. Decreased male sexual signalling could account for lower preferences of risky behaviors in females who are involved in longer lasting romantic relationships.
