Extending problem-solving procedures through reflection

A large-sample (n = 75) fMRI study guided the development of a theory of how people extend their problem-solving procedures by reflecting on them. Both children and adults were trained on a new mathematical procedure and then were challenged with novel problems that required them to change and extend their procedure to solve these problems. The fMRI data were analyzed using a combination of hidden Markov models (HMMs) and multi-voxel pattern analysis (MVPA). This HMM–MVPA analysis revealed the existence of 4 stages: Encoding, Planning, Solving, and Responding. Using this analysis as a guide, an ACT-R model was developed that improved the performance of the HMM–MVPA and explained the variation in the durations of the stages across 128 different problems. The model assumes that participants can reflect on declarative representations of the steps of their problem-solving procedures. A Metacognitive module can hold these steps, modify them, create new declarative steps, and rehearse them. The Metacognitive module is associated with activity in the rostrolateral prefrontal cortex (RLPFC). The ACT-R model predicts the activity in the RLPFC and other regions associated with its other cognitive modules (e.g., vision, retrieval). Differences between children and adults seemed related to differences in background knowledge and computational fluency, but not to the differences in their capability to modify procedures.     

Predictors of age-related and individual variability in autobiographical memory in childhood

ABSTRACT

Development of autobiographical memory is as a gradual process beginning in early childhood and continuing through late adolescence. Substantial attention has been paid to early childhood when first personal memories are formed; less attention has been focused on the flourishing of memories from the late preschool years onward. We addressed this void with a three-year cohort-sequential study of age-related changes in the length, completeness, and coherence of autobiographical narratives by children 4–10 years. We also examined the unique and combined variance in autobiographical narrative explained by children’s own language, maternal narrative style, domain-general cognitive abilities, non-autobiographical story recall, and memory-specific skills. There was substantial growth in autobiographical narrative skill across the 4–10-year period. Non-autobiographical story recall was a strong concurrent and cross-lagged predictor for all autobiographical narrative measures. Memory-specific and domain-general cognitive abilities systematically predicted narrative completeness and coherence but not length. Children’s language and maternal narrative style did not contribute additional variance when these predictors were considered. The findings highlight that age-related changes in autobiographical memory are the results of combined contributions of a variety of domain-general and domain-specific predictors.     

Individuality of Narratives Generated by Individuals: An Investigation Using Four-Panel Comics

In this study, we conducted an empirical research focusing on the generation of stories to obtain a hypothesis on how different the stories that people generate in their daily lives by linking events and situations are. For this purpose, five illustrations that revealed only the first and fourth panels of a four-panel comic were used as stimuli to generate a narrative in which the participants could make a connection between them. A total of 40 stories were obtained from eight participants. As a result, the narrative emerged in a variety of ways, even in events with little personal connection to the participants. This reveals that there are individual differences in the way people generate narratives themselves, despite their relationship with and position on the event. When the stories were typified, none of the participants generated similar stories in all five illustrations. This suggests that, because the combination of stories a person creates about every event is unique, there is only one story about the world, and one about himself/herself.     

How can a heterosexual man remove his body hair and retain his masculinity? Mapping stories of male body hair depilation

ABSTRACT

This study explores the gendered body hair removal norm and the meanings of male body hair by examining young people’s sense-making around male body hair removal. The novel technique of story completion was used to collect data from 102 psychology undergraduates. They were presented with a story “stem” featuring a young man (David) deciding to start body hair removal and asked to complete the stem. David was most often portrayed as a young heterosexual man who was excessively hairy, in the “wrong” places, was often subject to teasing and bullying, and was concerned about his diminished sexual capital. Hair removal did not always end “happily ever after” for David. While in some stories he “got the girl,” he was punished for his vanity and foolishness in others. These different endings arguably reflect currently ambivalent meanings around male body hair depilation. The production of a hairless, or less hairy, male body is both desirable and a potential threat to masculinity. The data spoke strongly to the power of social norms surrounding body hair practices and suggest that story completion provides a useful tool in interrogating the discourses that sustain these norms.     

Emotion regulation strategies in preschool children

This study investigated the development of emotion regulation strategies as reflected in the narratives of children between the ages of 3 and 6 years. An experimental procedure based on story completion tasks was devised to elicit the emotion‐related narratives of 69 preschool children. Coding of the narratives led to the observation of different emotion regulation strategies: Behavioural strategies, social support, and cognitive reappraisal. Several significant gender and age differences were identified in the use of these strategies. In addition, verbal skills, non‐verbal intelligence, and emotion comprehension were found to be associated with use of the observed emotion regulation strategies, although only at specific ages.     

Modeling the emergence of informational content by adaptive networks for temporal factorisation and criterial causation

Propagated activation of neurons through their network is an important process in the brain. Another crucial part of neural processing concerns adaptation over time of characteristics of this network such as connection strengths or excitability thresholds. This adaptation can be slow, as in learning from a multiple experiences, or it can be fast, as in memory formation. These adaptive network characteristics can be considered informational criteria for activation of a neuron. This then is viewed as a form of emergent information formation. Activation of neurons is determined by such information via a process termed criterial causation. In the current paper, the relationship of criterial causation with the principle of temporal factorisation for the dynamics of the world in general is explored. Temporal factorisation describes how the world represents information about its past in its present state, which then in turn determines the world’s future. In the paper, it is shown how these processes are analysed in more detail and modeled by (adaptive) network models.
