On what is bound in figures and grounds

All else being equal, regions providing a quick, good match to object memories are likely to be seen as shaped figures rather than as shapeless grounds. Good matches to object memories occur only if the parts are properly bound spatially. If object memories are accessed in the course of perceptual organization even for regions ultimately seen as shapeless grounds, then binding of parts cannot require attention to figures. Novel silhouette primes were shown immediately before real or novel line drawings. The silhouette contours of half of the primes preceding real line drawings sketched a known shape on the outside, which nevertheless appeared to be a shapeless ground. At short prime-line drawing SOAs, observers took longer to categorize real line drawings following these experimental primes than control primes, suggesting that parts are properly bound spatially for regions perceived to be shapeless grounds, and further that object memories matching grounds are inhibited.     

A cross-cultural study of hindsight bias and conditional probabilistic reasoning

Hindsight bias is a mistaken belief that one could have predicted a given outcome once the outcome is known. Choi and Nisbett (2000 Choi, I. and Nisbett, R. E. 2000. Cultural psychology of surprise: Holistic theories and recognition of contradiction. Journal of Personality and Social Psychology, 79: 890–905. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) reported that Koreans showed stronger hindsight bias than Americans, and explained the results using the distinction between analytic cognition (Westerners) and holistic cognition (Easterners). The purpose of the present study was to see whether hindsight bias is stronger among Easterners than among Westerners using a probability judgement task, and to test an “explicit–implicit” hypothesis and a “rule-dialectics” hypothesis. We predicted that the implicit process is more active among Easterners to generate hindsight bias, and that Easterners are more dialectical thinkers, whereas Westerners are more rule-based thinkers. French, British, Japanese, and Korean participants were asked to make probabilistic judgements in a Good Samaritan scenario (Experiment 1) and in a scenario including conditional probabilistic judgement (Experiment 2). In both Experiments, we presume that the implicit revision of causal models is made just by being given unexpected outcome information, and that explicit revision is made by being asked to point out possible factors for an unexpected outcome. In the results Easterners showed greater hindsight bias generally and it was greater in the Good Samaritan scenario. We conclude that the reason why hindsight bias was lower among Westerners is primarily that they tried to follow a rule to suppress the bias.     

Knowing what to look for: Voice affects face race judgements

The study examined the effect that auditory information (speaker language/accent: Japanese or French) had on the processing of visual information (the speaker's race: Asian or Caucasian) in two forced-choice tasks: Classification and perceptual judgement on animated talking characters. Two (male and female) sets of facial morphs were constructed such that a 3-D head of Caucasian appearance was gradually morphed (in 11 steps) into one of Asian appearance. Each facial morph was animated in association with spoken French/Japanese or English with a French/Japanese accent. To examine the auditory effect, each animation was played with or without sound. Experiment 1 used an Asian or Caucasian classification task. Results showed that faces heard in conjunction with Japanese or a Japanese accent were more likely to be classified as Asian compared to those presented without sound. Experiment 2 used a same or different judgement task. Results showed that accuracy was improved by hearing a Japanese accent compared to without sound. These results were discussed in terms of the voice information acting as a cue to assist in organizing and attending to face features.     

When bystanders become bothersome: The negative consequences of bystander conflict and the moderating role of resilience

Bystander conflict is a situation in which employees are hindered in their work by parties not involved in the primary process. Public service employees and emergency care workers, such as ambulance employees and firefighters, often encounter this kind of conflict with potentially far-reaching detrimental effects for public or patient safety. Unfortunately, until now, bystander conflict has hardly received scientific attention. In this paper, we will present the results of an experiment (Study 1) and a simulation study (Study 2). Taken together, the results indicate that bystander conflict is negatively related to the affective, behavioural, and cognitive outcomes of individuals. Higher levels of bystander conflict were associated with more negative and less positive feelings (Studies 1, 2), unfavourable bystander appraisals (Studies 1, 2), and lower levels of performance (Study 2). Additionally, Study 2 revealed that bystander conflict was negatively and indirectly related to positive affect and performance through cognitive capacity. We investigated the moderating role of resilience, in order to provide insight into potential factors alleviating these negative associations. In both studies, resilience alleviated the negative associations of bystander conflict. Overall, the results of the two studies provide a first step towards a theory on bystander conflict.     

The importance of social and ideal social dimensions in self‐congruity research

Chronic or situational self‐construal moderates the effects of four self‐congruity (SC) dimensions (i.e., actual, ideal, social, and ideal social) on brand evaluations. Past research has mainly focused on the actual and ideal SC effects; these effects have been found to be stronger than the social and ideal social SC effects. However, the findings of past research are based on samples from individualistic cultures. Individualists have a dominant independent self‐construal. We conduct two experiments to show that the social and ideal social SC effects are stronger than the actual and ideal SC effects for individuals with a dominant interdependent self‐construal. In Study 1, using samples from collectivistic cultures, four SC effects are compared. In Study 2, we examine how primed self‐construal, whether independent or interdependent, impacts the four SC effects. This research documents the importance of the social and ideal social dimensions in SC research.

Invited Address at the Occasion of the Bertelson Award 2005 Impairments in visual discrimination in amnesia: Implications for theories of the role of medial temporal lobe regions in human memory

A prominent and long-standing view of human long-term memory is that structures within the medial temporal lobe (MTL) work together to support the acquisition of memory for facts and events. In contrast to this view, recent studies in rats and non-human primates suggest dissociations in function between regions comprising the MTL. Evidence in support of such specialisation in humans, however, has been inconclusive, leading some researchers to propose that human MTL functions as a unitary system uniquely specialised for the acquisition and storage of long-term memory. This paper reviews some of the key studies from the animal and human literature that support an account of functional differentiation and discusses the different theoretical positions that have emerged from their findings. A series of recent experiments in humans designed to determine whether there is functional homogeneity in MTL regions across species are also reviewed and an alternative account of human memory—in which long-term memory is dependent upon representations distributed throughout the human brain rather than one specialised system—is proposed.     

Chronic psychological stress and the regulation of pro-inflammatory cytokines: a glucocorticoid-resistance model.

This study examined whether chronic stress impairs the immune system's capacity to respond to hormonal signals that terminate inflammation. Fifty healthy adults were studied; half were parents of cancer patients, and half were parents of healthy children. Parents of cancer patients reported more psychological distress than parents of healthy children. They also had flatter diurnal slopes of cortisol secretion, primarily because of reduced output during the morning hours. There was also evidence that chronic stress impaired the immune system's response to anti-inflammatory signals: The capacity of a synthetic glucocorticoid hormone to suppress in vitro production of the pro-inflammatory cytokine interleukin-6 was diminished among parents of cancer patients. Findings suggest a novel pathway by which chronic stress might alter the course of inflammatory disease.     

The effect of repeated experience on children's suggestibility across two question types

There is a discrepancy in the literature regarding the effect of repeated experience on children's suggestibility. Some researchers have concluded that repeated experience increases children's suggestibility for variable details whereas others have reported no detrimental effect. This study demonstrated that the type of question used to test memory (cued‐recall versus yes/no questions) could account for the different reported conclusions. Children aged 5–6 years took part in an event either once or four times. Three or 21 days later, they were given a suggestive interview about the single/final occurrence of the event during which half of the event details were inaccurately described. When later asked yes/no questions, the children with repeated experience agreed with more of the suggestions than did those in the single‐experience condition, especially at the longer delay. In relation to cued‐recall questions, however, experience did not mediate the number of times that false suggestions from the biasing interview were reported. This latter finding was revealed irrespective of the retention interval. Copyright © 2002 John Wiley & Sons, Ltd.     

Treatment Adherence in Children with Sickle Cell Disease: Disease-Related Risk and Psychosocial Resistance Factors

To identify disease-related risk factors and psychosocial resistance factors that impact adherence to prescribed treatment in the context of admission to a Hematology Acute Care Unit (HACU) designed to provide acute care for children with sickle cell disease (SCD) presenting with pain or fever. A total of 73 primary caregivers and 24 children (if age 8 or older) completed standardized forms during the HACU admission. Treatment adherence variables (medical staff rating, SCD-related care activities, percentage of agreement between treatment recommendations made and care activities, and attendance at hematology clinic) indicated moderate-to-high adherence. Based on regression analyses, the risk variable of disease-related stress and the resistance variables of family flexibility and less reliance on passive coping accounted for significant portions of the variance in treatment adherence. Empirical evaluation of interventions designed to improve communication regarding expectations for the care of children with SCD and to support active family problem solving during times of SCD-related stress must be ongoing.
