A new look at “the hard problem” of bilingual lexical access: evidence for language-switch costs with univalent stimuli

Considerable work has used language-switching tasks to investigate how bilinguals manage competition between languages. Language-switching costs have been argued to reflect persisting inhibition or persisting activation of a non-target language. However, these costs might instead reflect the use of bivalent stimuli (i.e. pictures or digits that can be responded to in either language). That is, language-switching costs may simply reflect a cost of selecting the task-appropriate response for a given item and so may not be reflective of bilingual lexical access [Finkbeiner, M., Almeida, J., Janssen, N., & Carramaza, A. (2006). Lexical selection in bilingual speech production does not involve language suppression. Journal of Experimental Psychology: Learning, Memory, and Cognition, 32(5), 1075–1089]. The present study addresses this concern by having Chinese/English bilinguals switch between languages in response to inherently univalent stimuli (English words and Chinese Characters) as well as lexically univalent, but orthographically bivalent, stimuli (English words and Chinese Pinyin). Speakers showed switch costs when naming both univalent and orthographically bivalent stimuli, showing that switch costs can be found even with inherently univalent stimuli.     

Inference in the Wild: A Framework for Human Situation Assessment and a Case Study of Air Combat

Situation awareness is a key construct in human factors and arises from a process of situation assessment (SA). SA comprises the perception of information, its integration with existing knowledge, the search for new information, and the prediction of the future state of the world, including the consequences of planned actions. Causal models implemented as Bayesian networks (BNs) are attractive for modeling all of these processes within a single, unified framework. We elicited declarative knowledge from two Royal Australian Air Force (RAAF) fighter pilots about the information sources used in the identification (ID) of airborne entities and the causal relationships between these sources. This knowledge was represented in a BN (the declarative model) that was evaluated against the performance of 19 RAAF fighter pilots in a low‐fidelity simulation. Pilot behavior was well predicted by a simple associative model (the behavioral model) with only three attributes of ID. Search for information by pilots was largely compensatory and was near‐optimal with respect to the behavioral model. The average revision of beliefs in response to evidence was close to Bayesian, but there was substantial variability. Together, these results demonstrate the value of BNs for modeling human SA.     

Stereotype threat strengthens automatic recall and undermines controlled processes in older adults

The threat of being judged stereotypically (stereotype threat) may impair memory performance in older adults, thereby producing inflated age differences in memory tasks. However, the underlying mechanisms of stereotype threat in older adults or other stigmatized groups remain poorly understood. Here, we offer evidence that stereotype threat consumes working memory resources in older adults. More important, using a process-dissociation procedure, we found, for the first time, that stereotype threat undermines the controlled use of memory and simultaneously intensifies automatic response tendencies. These findings indicate that competing models of stereotype threat are actually compatible and offer further reasons for researchers and practitioners to pay special attention to age-related stereotypes during standardized neuropsychological testing.     

Cognitive processes in psychological adaptation to miscarriage: A preliminary report

Abstract

Twenty-two women who wished to continue their pregnancies were interviewed several months after their first miscarriage. Levels of anxiety and depression showed an extremely high degree of variability. Cognitive processes in the form of a search for meaning, mastery and self-enhancement hypothesised to be important in adaptation to negative events were assessed. Having an explanation for the miscarriage and the experience leading to a general reappraisal of values were associated with lower levels of intrusive thoughts. A belief in a medical cause was linked to lower anxiety. Women believed that neither they themselves nor their doctors could exert much influence over the outcome of future pregnancies. Stronger belief in personal control was associated with higher anxiety levels. There is a need to consider not only the emotional consequences of miscarriage but also the cognitive mediators influencing such responses and although based upon a small sample this study initiates that process.     

Second-Order Change in Marriage and Family Therapy: A Web-Based Modified Delphi Study

Second-order change is a central concept in Marriage and Family Therapy, but still remains poorly operationalized. We conducted a web-based modified Delphi study with 31 established faculty members currently teaching in COAMFTE-accredited Master's and Doctoral programs in the United States and in Canada to identify consensus regarding second-order change concepts, clinical operationalization, evaluation, and teaching principles. Numerous exemplars of first and second-order change were generated, but consensus on most items was low. Consensus was highest for pedagogy and low regarding concepts and clinical examples of first-order change and evaluation of second-order change. Results suggest clearer definitions and better measurement of systemic change are needed.     

Children and Adolescents of Cancer Patients: The Impact of Cancer on the Family

In this article, extant literature was reviewed to examine the impact of parental cancer on the family. Many researchers and scholars have hypothesized that parental illnesses, like cancer, can affect all levels of the family system. However, most psychosocial research to date has focused on how cancer affects the patient and the couple. Consequently, little is known about how parental cancer affects the psychosocial development of children and adolescents. Therefore, research is needed to explore how children and adolescents are negatively impacted or protected from the effects of living with a parent who has cancer. More specifically, longitudinal studies that examine the mechanisms by which the cancer affects children's and adolescents' functioning can help physicians and family therapists clinically intervene in more efficacious ways.     

Accounts of workplace bullying: The role of the organization

In over a decade of research into bullying at work, the focus has been on defining, measuring, and explaining the essential nature of the bullying phenomenon. This focus has positioned the individual as the main unit of analysis, with the organization acting as a facilitating backdrop. By assuming a critical research position as opposed to the dominant positivist tradition from which most of the bullying research emanates, attention can be drawn to additional and marginalized accounts. Our research does not offer a definition of bullying—rather, we examine the implications of the different ways in which the term bullying is used. This paper uses data from a case study in a large telecommunications company's call centres. We demonstrate that while employees use the pathologized individual and the facilitating environment to account for bullying, in addition they use the notion of the pathologized organization. This additional narrative brings issues of power and politics in organizations to the fore. Taking a critical management approach, we focus on employee accounts of the oppressive impact of power structures. We argue that marginalizing certain accounts functions to maintain the organizational power balance. By using the term bullying to describe their work experience, employees in this study sought to employ an emotive and highly charged term to highlight their discontent at increasingly difficult work situations.     

Infant interest in their mother's face is associated with maternal psychological health

Early experience can alter infants’ interest in faces in their environment. This study investigated the relationship between maternal psychological health, mother–infant bonding, and infant face interest in a community sample. A visual habituation paradigm was used to independently assess 3.5-month old infants’ attention to a photograph of their mother's face and a stranger's face. In this sample of 54 healthy mother–infant pairs, 57% of mothers (N = 31) reported symptoms of at least one of stress response to trauma, anxiety, or depression. Interest in the mother-face, but not stranger-face, was positively associated with the mother's psychological health. In regression analyses, anxiety and depression predicted 9% of the variance in looking to the mother-face. Anxiety was the only significant predictor within the model. No direct associations were found between mother–infant bonding and infants’ face interest. Taken together, these findings indicate that infant's visual engagement with their mother's face varies with maternal symptoms of emotional distress, even within a community sample.
