Cultures of moderation and expression: emotional experience, behavior, and physiology in Chinese Americans and Mexican Americans

Ethnographic accounts suggest that emotions are moderated in Chinese cultures and expressed openly in Mexican cultures. The authors tested this notion by comparing subjective, behavioral, and physiological aspects of emotional responses to 3 (warned, unwarned, instructed to inhibit responding) aversive acoustic startle stimuli in 95 Chinese Americans and 64 Mexican Americans. Subjective reports were consistent with ethnographic accounts; Chinese Americans reported experiencing significantly less emotion than Mexican Americans across all 3 startle conditions. Evidence from a nonemotional task suggested that these differences were not artifacts of cultural differences in the use of rating scales. Few cultural differences were found in emotional behavior or physiology, suggesting that these aspects of emotion are less susceptible to cultural influence.     

Personality and creativity

Previous research has provided conflicting accounts of the effects of personality on creative behaviour. This study examines the issue by means of factor analysis and multivariate analysis of variance. Different measures of creative behaviour and cognitive abilities are correlated with personal characteristics such as psychoticism, extraversion and other measures of personality. The results are consistent with the idea that different forms of creative behaviour are related to distinct characteristics of personality.     

Changing environmental context does not reliably affect memory

Most current theories of human memory propose that context, defined here as the time and place at which an event was experienced, forms an integral feature of the mnemonic representation of events. One way of investigating context is by manipulating the environmental context (which typically means the room in which the experiment takes place). The predominant result of this manipulation reported in the literature has been consistent with theory: Memory performance is better when the learning and testing environments are the same than when they differ. This article reports eight experiments that in aggregate challenge the reliability of this same-context advantage. Experiment 1 reported a failure to obtain a same-context advantage. Experiments 2–7 investigated various features of the design that might have reduced the effect. None of these experiments produced a reliable same-context advantage. Experiment 8 repeated the methodology of a published report of a same-context advantage with more than double the number of subjects, but failed to replicate the effect. An analysis of features of the experiments led to two suggestions for future investigations of the effects of changes in environmental context on memory.     

“Identify-to-reject”: A specific strategy to avoid false memories in the DRM paradigm

Previous research using the Deese–Roediger–McDermott (DRM) paradigm has shown that lists of associates in which the critical words were easily identified as the themes of the lists produce lower levels of false memories in adults. In an attempt to analyze whether this effect is due to the application of a specific memory-editing process (the identify-to-reject strategy), two experiments manipulated variables that are likely to disrupt this strategy either at encoding or at retrieval. In Experiment 1, lists were presented at a very fast presentation rate to reduce the possibility of identifying the missing critical word as the theme of the list, and in Experiment 2, participants were pressed to give yes/no recognition answers within a very short time. The results showed that both of these manipulations disrupted the identifiability effect, indicating that the identify-to-reject strategy and theme identifiability play a major role in the rejection of false memories in the DRM paradigm.     

Influence of the social context on use of surgical-lengthening and group-empowering coping strategies among people with dwarfism

Objective: To assess the role that social contextual factors exert on the way people with disproportionate short stature (dwarfism) cope with the negative consequences of discrimination. Method: Using multigroup structural equation modeling, we compare the coping process of people with dwarfism from Spain (N = 63) and the USA (N = 145), two countries that differ in the role played by organizations offering support to people with dwarfism. Results: In Spain, where organizational support is recent, a coping approach aimed at achieving integration with the majority group through limb-lengthening surgery prevails; in the USA, where the long-standing organization of people with dwarfism encourages pride in being a "little person" and positive intragroup contact, a coping strategy based on empowering the minority group dominates. Conclusions: Both strategies, each in its own context, are effective at protecting psychological well-being from the negative consequences of stigmatization; however, they exert their positive effects through different processes.

Visual object categorization in birds and primates: Integrating behavioral,neurobiological, and computational evidence within a “general process” framework

Previous comparative work has suggested that the mechanisms of object categorization differ importantly for birds and primates. However, behavioral and neurobiological differences do not preclude the possibility that at least some of those mechanisms are shared across these evolutionarily distant groups. The present study integrates behavioral, neurobiological, and computational evidence concerning the “general processes” that are involved in object recognition in vertebrates. We start by reviewing work implicating error-driven learning in object categorization by birds and primates, and also consider neurobiological evidence suggesting that the basal ganglia might implement this process. We then turn to work with a computational model showing that principles of visual processing discovered in the primate brain can account for key behavioral findings in object recognition by pigeons, including cases in which pigeons’ behavior differs from that of people. These results provide a proof of concept that the basic principles of visual shape processing are similar across distantly related vertebrate species, thereby offering important insights into the evolution of visual cognition.
