Cognitive Control of Attentional Guidance by Visual and Verbal Working Memory Representations

Both visual and verbal information in working memory guide visual attention toward a memory‐matching object. We tested whether: (a) visual and verbal representations have different effects on the deployment of attention; and (b) both types of representations can be used equally in a top‐down manner. We asked participants to maintain a visual cue or a verbal cue at the beginning of each trial, and ended with a memory task to ensure that each cue was represented actively in working memory. Before the memory task, a visual search task appeared where validity was manipulated as valid, neutral, or invalid. We also manipulated the probability of valid trials (20%, 50%, and 80%), which had been told to the participants prior to the task. Consistent with earlier findings, attentional guidance by visual representations was modulated by the probability. We also found that this was true for verbal representations, and that these effects did not differ between representation types. These results suggest that both visual and verbal representations in working memory can be used strategically to control attentional guidance.     

Predictors of Living in Precarious Housing Among Immigrants Accessing Housing Support Services

The purpose of this study was to identify factors that explain immigrant housing vulnerability, thereby contributing to the growth of a more substantial knowledge base on the intersection between immigration, housing and homelessness. Administrative data on housing support service recipients (n?=?4168) in Alberta, Canada, were analysed to determine the varied demographic, socio-economic and health-related factors that contribute to living in a precarious housing situation (such as homelessness, couch surfing, staying with friends or family etc.). Logistic regression analysis shows that being an immigrant is a protective factor from living in a precarious housing situation. For the immigrant subsample (n?=?525), logistic regression analysis demonstrates that living in a larger city, having a mental illness and being married were protective factors from living in a precarious housing situation. However, having an addiction and being precariously employed (such as only working part-time, having temporary employment or being unemployed) were risk factors for living in a precarious housing situation. Shared and distinctive vulnerabilities among the immigrant subsample and the full study sample are discussed, along with implications for specific policy and programmes that aim to address the housing needs of immigrants.
