Bringing together humanistic and intergroup perspectives to build a model of internalisation of normative social harmdoing

This article introduces a model of the internalisation of normative social harmdoing: the MINSOH. This model seeks to explain how group members internalise harmful social norms such that they personally endorse their groups' normative actions. To this aim, the MINSOH integrates two divergent yet complementary theoretical perspectives: self-determination theory and the social identity approach. These perspectives differ in their basic assumptions about the possibility for harm to become internalised, yet when integrated, they provide a powerful account of how harmdoing can become internalised. The MINSOH proposes specific conditions under which harmful normative actions become accepted by group members. This article outlines multiple self-determined motivations for harmdoing and discrete group processes that enable harmdoing to be internalised and autonomously enacted, and reviews factors that facilitate (i.e., strong/unique/comparative social identification; endorsement of ideological justifications) and block the internalisation process (presence of multiple identities/diverging norms; inclusive superordinate identity). Directions for future research are then discussed.

Confirmatory reinforcement learning changes with age during adolescence

Understanding how learning changes during human development has been one of the long-standing objectives of developmental science. Recently, advances in computational biology have demonstrated that humans display a bias when learning to navigate novel environments through rewards and punishments: they learn more from outcomes that confirm their expectations than from outcomes that disconfirm them. Here, we ask whether confirmatory learning is stable across development, or whether it might be attenuated in developmental stages in which exploration is beneficial, such as in adolescence. In a reinforcement learning (RL) task, 77 participants aged 11–32 years (four men, mean age = 16.26) attempted to maximize monetary rewards by repeatedly sampling different pairs of novel options, which varied in their reward/punishment probabilities. Mixed-effect models showed an age-related increase in accuracy as long as learning contingencies remained stable across trials, but less so when they reversed halfway through the trials. Age was also associated with a greater tendency to stay with an option that had just delivered a reward, more than to switch away from an option that had just delivered a punishment. At the computational level, a confirmation model provided increasingly better fit with age. This model showed that age differences are captured by decreases in noise or exploration, rather than in the magnitude of the confirmation bias. These findings provide new insights into how learning changes during development and could help better tailor learning environments to people of different ages.

Research Highlights

• Reinforcement learning shows age-related improvement during adolescence, but more in stable learning environments compared with volatile learning environments.
• People tend to stay with an option after a win more than they shift from an option after a loss, and this asymmetry increases with age during adolescence.
• Computationally, these changes are captured by a developing confirmatory learning style, in which people learn more from outcomes that confirm rather than disconfirm their choices.
• Age-related differences in confirmatory learning are explained by decreases in stochasticity, rather than changes in the magnitude of the confirmation bias.

     

Pitch Range Variations Improve Cognitive Processing of Audio Messages

This study explores the effect of different speaker intonation strategies in audio messages on attention, autonomic arousal, and memory. In this study, participants listened to 16 radio commercials, produced to vary in pitch range across sentences. Dependent variables were self‐reported effectiveness and adequacy, psychophysiological arousal and attention, immediate word recall and recognition of information. Results showed that messages conveyed with pitch variations achieved better scores compared to commercials with a homogenous pitch range across the sentences. This was especially the case when high pitch intonation was followed by low pitch within a sentence. The results increase our understanding of the influence of pitch range on processing by establishing a concrete strategy as a best practice for improving attention and memory.     

Does colour preference have a role in colour term acquisition?

A developmental association exists between colour preference and emerging colour term acquisition in young children. Colour preference might influence colour term acquisition by directing attention towards or away from a particular colour, making it more or less memorable. To investigate the role that colour preference may have in the acquisition of colour terms, experimental tasks of colour preference, discrimination, attention, memory, and new colour term learning, were given to three groups of participants (preschool children; primary school children; and adults). Each task utilized the same colour stimuli, which were four computer‐simulated colours, matched perceptually to four different Munsell chips, drawn from the same colour category. Three colours varied systematically from an anchor colour (10PB 4/8) only in saturation (10PB 4/4), luminance (10PB 6/8), or hue (5P 4/8). Results showed that within‐category colour preferences emerged with age, and that when established within individuals, most preferred colours were named significantly more accurately than least preferred colours, although this association did not appear to be mediated directly by attention or memory. Rather, perceptual saliency was shown to have a mediating role, to some extent, in determining the relationship between colour preference and the cognitive processing of colour.
