Can We Identify with a Nation Low in Morality? The Heavy Weight of (Im)Morality in International Comparison

Research has shown that the perceived morality of the ingroup is a primary source of group pride and ingroup identification. The present research examined whether this is true even when a group has a poor reputation for morality in terms of dishonesty and corruption, such as in the case of Italians. To address this issue, two studies analyzed the role of the three fundamental dimensions of social judgment—morality, competence, and sociability—in predicting Italians’ identification with their nation when the salience of social comparison and the status of the comparison outgroup were varied. Findings showed that perceived morality predicted ingroup identification when participants did not engage in social comparison. Under salient social comparison, individuals based group identification on other dimensions: Perceived sociability was the main predictor of identification when respondents compared with a higher status outgroup (Germans; Study 1; N = 109), whereas perceived competence was the main predictor of identification when participants compared with a lower status outgroup (Romanians; Study 2; N = 121). Overall, findings showed compensation processes in social identification: When social comparison is salient, members of a low morality group base identification on the dimension which allows positive differentiation from the outgroup.     

Small-sample characterization of stochastic approximation staircases in forced-choice adaptive threshold estimation

Despite the widespread use of up-down staircases in adaptive threshold estimation, their efficiency and usability in forced-choice experiments has been recently debated. In this study, simulation techniques were used to determine the small-sample convergence properties of stochastic approximation (SA) staircases as a function of several experimental parameters. We found that satisfying some general requirements (use of the accelerated SA algorithm, clear suprathreshold initial stimulus intensity, large initial step size) the convergence was accurate independently of the spread of the underlying psychometric function. SA staircases were also reliable for targeting percent-correct levels far from the midpoint of the psychometric function and performed better than classical up-down staircases with fixed step size. These results prompt the utilization of SA staircases in practical forced-choice estimation of sensory thresholds.     

Visual distortion of body size modulates pain perception

Pain is a complex subjective experience that is shaped by numerous contextual factors. For example, simply viewing the body reduces the reported intensity of acute physical pain. In this study, we investigated whether this visually induced analgesia is modulated by the visual size of the stimulated body part. We measured contact heat-pain thresholds while participants viewed either their own hand or a neutral object in three size conditions: reduced, actual size, or enlarged. Vision of the body was analgesic, increasing heat-pain thresholds by an average of 3.2 °C. We further found that visual enlargement of the viewed hand enhanced analgesia, whereas visual reduction of the hand decreased analgesia. These results demonstrate that pain perception depends on multisensory representations of the body and that visual distortions of body size modulate sensory components of pain.     

The Effect of Symbolic Distancing on Delay Tolerance across the Preschool Period

ABSTRACT

We aimed to longitudinally examine how symbolic distancing affects preschool children’s delay tolerance in a delay choice task. We presented children with choices between a smaller immediate reward and a larger delayed reward in conditions with either symbolic stimuli or edible rewards. Overall, symbolic distancing modulated children’s delay tolerance. In particular, whereas in the first phase (T1: 3- and 4-year-olds) children presented with edible rewards chose the larger option more often than children presented with symbolic stimuli, in the second phase (T2: 5- and 6-year-olds), there was no significant difference between children presented with symbolic stimuli and those presented with edible rewards. These results are discussed by examining how children’s delay tolerance changes during the development and comparing children to adult humans in a similar task.
