Chunking mechanisms in human learning

Pioneering work in the 1940s and 1950s suggested that the concept of 'chunking' might be important in many processes of perception, learning and cognition in humans and animals. We summarize here the major sources of evidence for chunking mechanisms, and consider how such mechanisms have been implemented in computational models of the learning process. We distinguish two forms of chunking: the first deliberate, under strategic control, and goal-oriented; the second automatic, continuous, and linked to perceptual processes. Recent work with discrimination-network computational models of long- and short-term memory (EPAM/CHREST) has produced a diverse range of applications of perceptual chunking. We focus on recent successes in verbal learning, expert memory, language acquisition and learning multiple representations, to illustrate the implementation and use of chunking mechanisms within contemporary models of human learning.     

Social Comparison and Satisfaction: Students' Reactions After Exam Feedback Predict Future Academic Performance1

These studies examined the relations among performance satisfaction, choice of social comparison targets, and subsequent performance in a classroom setting. Previous research has shown that comparison with high performers helps academic performance. In 2 field studies, this relation was moderated by satisfaction with initial performance. After learning their scores on the first exam of the semester, students indicated their satisfaction with the scores and performance level of someone with whom they would like to compare exams. Comparison with poor performers was beneficial when coupled with dissatisfaction. Dissatisfied students who preferred comparison with poor performers improved over the semester.     

How Children and Adults Represent God's Mind

For centuries, humans have contemplated the minds of gods. Research on religious cognition is spread across sub‐disciplines, making it difficult to gain a complete understanding of how people reason about gods' minds. We integrate approaches from cognitive, developmental, and social psychology and neuroscience to illuminate the origins of religious cognition. First, we show that although adults explicitly discriminate supernatural minds from human minds, their implicit responses reveal far less discrimination. Next, we demonstrate that children's religious cognition often matches adults' implicit responses, revealing anthropomorphic notions of God's mind. Together, data from children and adults suggest the intuitive nature of perceiving God's mind as human‐like. We then propose three complementary explanations for why anthropomorphism persists in adulthood, suggesting that anthropomorphism may be (a) an instance of the anchoring and adjustment heuristic; (b) a reflection of early testimony; and/or (c) an evolutionary byproduct.     

Stable middle-aged face recognition: No moderation of the own-age bias across contexts

The own-age bias (OAB) has been proposed to be caused by perceptual expertise and/or social-cognitive mechanisms. Investigations into the role of social cognition have, however, yielded mixed results. One reason for this might be the tendency for research to focus on the OAB in young adults, between young and older adult faces where other-age individuation experience is low. To explore whether social-cognitive manipulations may be successful when observers have sufficient other-age individuation experience, we examined biases involving middle-aged other-age faces and the influence of a context manipulation. Across four experiments, young adult participants were presented with middle-aged faces alongside young or older adult faces to remember. We predicted that in contexts where middle-aged faces were positioned as other-age faces (alongside young adult faces), recognition performance would be worse than when they were positioned as relative own-age faces (alongside older adult faces). However, the context manipulations did not moderate middle age face recognition. This suggests that past findings that context does not change other-age face recognition holds for other-age faces for which observers have higher individuation experience. These findings are consistent with a perceptual expertise account of the OAB but more investigation of the generality of these results is required.     

The Role of Social Support,Being Present,and Self‐kindness in University Student Psychological Distress

Objective

Self‐kindness, which is thought to be part of self‐compassion, has the potential to contribute to mental health, as well as serve as a focus for interventions. However, little attention has been given to the potential role of self‐kindness specifically, especially in the context of mindful presence and available social support, in buffering distress.

Method

Structural equation modelling was used to test a theoretically based model of how these factors relate to each other and psychological distress. Participants were 592 Australian university students.

Results

Results confirmed our hypotheses, showing that: (a) receiving social support is important to the capacity for self‐kindness both directly and indirectly through the ability to “be present,” and (b) the relationship between social support and psychological distress is partially mediated by the practices of self‐kindness and being present. The model of social support, being present, and self‐kindness accounted for half the variance in psychological distress. With the addition of stressors, a regression model explained a total of 62% of the variance.

Conclusions

These findings have implications for understanding the construct of self‐kindness and its role in the development of interventions to improve student success.

Understanding the richness of brand relationships: Research dialogue on brands as intentional agents

This essay offers some perspectives on Kervyn et al.'s insightful research on brand relationships and the role of perceived intentions and ability. After briefly discussing the importance of brand knowledge and functionality in understanding the diversity of brand relationships, some other antecedents and consequences of brand relationships are reviewed. Three antecedents of corporate credibility — expertise, trust, and likability — are suggested as another means to differentiate how consumers view different brands. Brand resonance — an intense, active loyalty relationship — is also suggested as an important outcome of brand relationships. The essay concludes by noting that any concept as complex as brand relationships lends itself to multiple concepts, perspectives, and analysis.
