Intersensory redundancy accelerates preverbal numerical competence

Intersensory redundancy can facilitate animal and human behavior in areas as diverse as rhythm discrimination, signal detection, orienting responses, maternal call learning, and associative learning. In the realm of numerical development, infants show similar sensitivity to numerical differences in both the visual and auditory modalities. Using a habituation-dishabituation paradigm, we ask here, whether providing redundant, multisensory numerical information allows six-month-old infants to make more precise numerical discriminations. Results indicate that perceptually redundant information improved preverbal numerical precision to a level of discrimination previously thought attainable only after additional months of development. Multimodal stimuli may thus boost abstract cognitive abilities such as numerical competence.     

From psychosocial equilibrium to catastrophic breakdown: Cyprus 1955–1974

The recent history of Cyprus presents an example of a society in which a centuries-long peaceful coexistence of diverse populations gave way to violence and murderous hate, with devastating end results. This paper tries to understand and describe the process by which Cypriot society slid from a position of psychosocial equilibrium and integration towards one of disintegration, fragmentation and catastrophic breakdown. This paper draws from work by social anthropologists, sociologists, historians and others, and from my own personal experience. To these I applied insights afforded by psychoanalysis to identify and explore the psychic processes and states of mind that characterized a psychosocial disintegrative process. I came to see external political events and internal psychological processes as inseparably intertwined and dynamically interdependent, each emanating from and catalysing the other. The factual details of the process described are of course unique in their local specificity, but the psychic phenomena that characterized it are not: at both the individual and group levels they are replicated in other societies undergoing similar processes of self-destruction.     

Social power and emotional experience: Actor and partner effects within dyadic interactions

A dyadic methodological and statistical approach to social power is used to test the notion that an individual’s power and a partner’s power have distinct effects on the individual’s emotional experience. Two studies examined actor and partner effects of social power on emotion within dyadic interactions. Across interpersonal contexts and measures of social power, the individual’s own social power, theorized to activate behavioral approach, was associated with positive emotion (an actor effect). In contrast, being subject to a partner’s elevated social power, theorized to activate behavioral inhibition, was associated with increased negative emotion (a partner effect). The discussion focuses on how dyadic methodological and statistical approaches point to new lines of inquiry in the study of social power.     

Implicit emotional biases in decision making: the case of the Iowa Gambling Task

Many authors have endorsed the hypothesis that previous emotional experiences may exert a covert influence on behavior, but some findings and replications of the original studies challenged this view. We investigated this topic by carrying out an experiment with the Iowa Gambling Task (IGT), where a dissociation procedure was adopted to successfully isolate possible implicit components. After a typical interaction with the IGT, participants performed a "blind" card selection phase without receiving any feedback. Half of them were instructed to continue choosing as they did before, the other half was told that good card decks turned bad, and vice versa, so that explicit knowledge was necessary to overcome the previously learned deck-outcome associations. The results confirmed the existence of early acquired implicit biases, confirming that previously experienced emotional events may covertly affect subsequent behavior.     

Economic Disadvantage in Complex Family Systems: Expansion of Family Stress Models

Economic disadvantage is associated with multiple risks to early socioemotional development. This article reviews research regarding family stress frameworks to model the pathways from economic disadvantage to negative child outcomes via family processes. Future research in this area should expand definitions of family and household to incorporate diversity and instability. This expansion would be particularly relevant for research among low-income ethnic minority families and families with young children. This line of research would highlight specific pathways to target to prevent the onset of early parental and child dysfunction.     

Positive attributional style,life events and their effect on children's mood: Prospective study

The present study extended previous research into the role of cognitive style in predicting depressive symptoms in children by examining positive attributional style for positive events in a prospective manner, with a focus on the influence of prior life experience. A non‐clinical sample of 102 children (aged 10–12 years) was recruited. Participants completed self‐report measures of depression, attributional style, stressful life events, and positive life events on two occasions (approximately 6 months apart). Positive attributional style for positive events moderated the relationship between negative life events and follow‐up depressive symptoms. Number of positive events did not significantly moderate the negative life events–depression symptoms relationship although there was a trend in the expected direction. Positive attributional style for positive events appeared to act as both a mediator and moderator in the positive events–depression symptoms relationship. Theoretical and clinical implications of these findings are discussed.     

Ubiquity of Whiteness in majority group national imagination: Australian = White,but New Zealander does not

This research examined cross‐national differences in the extent to which majority ethnic group members (White Europeans) in Australia and New Zealand automatically privileged members of their ingroup, relative to Indigenous targets, in cognitive representations of nationhood. As predicted, European Australian undergraduates implicitly associated their own ethnic group with the concept of “Australian”, relative to Aboriginal Australian targets (N = 50), but the implicit preferencing of Whiteness in representations of nationhood (relative to Maori targets) was absent in a comparable sample of New Zealand European undergraduates (N = 50). These results indicate that the extent to which representations of minority groups are interwoven with non‐conscious cognitive representations of nationhood and national identity are not immutably fixed. Instead, it is argued that this cross‐national difference is due to underlying systemic differences in the extent to which symbolic markers of Indigenous culture, identity, and values are consensually represented in majority group (White) national culture.     

Contexts and control operations used in accessing list-specific, generalized, and semantic memories

The human ability to focus memory retrieval operations on a particular list, episode or memory structure has not been fully appreciated or documented. In Experiment 1-3, we make it increasingly difficult for participants to switch between a less recent list (multiple study opportunities), and a more recent list (single study opportunity). Task performance was good, although there was a cost associated with switching. In Experiment 4, list-specific learning experiences were used to create a generalized memory as a step towards semantic memory. List-specific memories intruded during attempts to retrieve the generalized memory and the generalized memory enhanced list-specific performance. The generalized memory also intruded in a free-association task. We propose that a hierarchy of contexts and control operations underlie the human ability to access different memory structures and that there is no sharp discontinuity in the control operations needed to access list-specific, generalized, and semantic memories.
