Improving intergroup relations between Catholics and Protestants in Northern Ireland via E-contact

Northern Ireland is characterised by extensive segregation between its predominantly Catholic and Protestant communities. With the aim of overcoming this segregation, the current study experimentally evaluated the effectiveness of electronic or E-contact as a novel indirect contact and prejudice-reduction strategy. Here, Catholic and Protestant participants were not required to meet physically but were involved in a collaborative and goal-orientated online interaction with a member of the other community. As predicted, E-contact improved both Catholics’ and Protestants’ outgroup attitudes via improved contact expectancies and reduced intergroup anxiety. These findings provide support for the contemporary role of online interactions in actively overcoming the physical and psychological barriers that often prevent prejudice reduction in segregated communities.

Expertise and recollective experience: recognition memory for familiar and unfamiliar academic subjects

Two experiments investigated whether expertise effects in recognition memory could be found for different academic subjects. The roles of subjective experience and repetition on such effects were also explored. Experiment 1 showed that overall recognition memory was greater for familiar than for unfamiliar academic words (the expertise effect). Additionally, this effect was attributable to the subjective experience of remembering rather than knowing. Experiment 2 showed that repetition of stimulus items at study eliminated these expertise effects. Previous research has generally failed to find expertise effects in overall recognition memory. The present findings show that expertise effects do occur in overall recognition memory and are associated with the richer memorial experience of remembering rather than knowing.

No intrinsic number bias: Evaluating the role of perceptual discriminability in magnitude categorization

Accumulating evidence suggests that there is a spontaneous preference for numerical, compared to non-numerical (e.g., cumulative surface area), information. However, given a paucity of research on the perception of non-numerical magnitudes, it is unclear whether this preference reflects a specific bias towards number, or a general bias towards the more perceptually discriminable dimension (i.e., number). Here, we found that when the number and area of visual dot displays were matched in mathematical ratio, number was more perceptually discriminable than area in both adults and children. Moreover, both adults and children preferentially categorized these ratio-matched stimuli based on number, consistent with previous work. However, when number and area were matched in perceptual discriminability, a different pattern of results emerged. In particular, children preferentially categorized stimuli based on area, suggesting that children's previously observed number bias may be due to a mismatch in the perceptual discriminability of number and area, not an intrinsic salience of number. Interestingly, adults continued to categorize the displays on the basis of number. Altogether, these findings suggest a dominant role for area during childhood, refuting the claim that number is inherently and uniquely salient. Yet they also reveal an increased salience of number that emerges over development. Potential explanations for this developmental shift are discussed.

Research Highlights

• Previous work found that children and adults spontaneously categorized dot array stimuli by number, over other magnitudes (e.g., area), suggesting number is uniquely salient.
• However, here we found that when number and area were matched by ratio, as in prior work, number was significantly more perceptually discriminable than area.
• When number and area were made equally discriminable (‘perceptually-matched’), children, contra adults, spontaneously categorized stimuli by area over number (and other non-numerical magnitudes).
• These findings suggest that area may be uniquely salient early in childhood, with the previously-observed number bias not emerging until later in development.
