Does neighborhood size really cause the word length effect?

In short-term serial recall, it is well-known that short words are remembered better than long words. This word length effect has been the cornerstone of the working memory model and a benchmark effect that all models of immediate memory should account for. Currently, there is no consensus as to what determines the word length effect. Jalbert and colleagues (Jalbert, Neath, Bireta, & Surprenant, 2011a; Jalbert, Neath, & Surprenant, 2011b) suggested that neighborhood size is one causal factor. In six experiments we systematically examined their suggestion. In Experiment 1, with an immediate serial recall task, multiple word lengths, and a large pool of words controlled for neighborhood size, the typical word length effect was present. In Experiments 2 and 3, with an order reconstruction task and words with either many or few neighbors, we observed the typical word length effect. In Experiment 4 we tested the hypothesis that the previous abolition of the word length effect when neighborhood size was controlled was due to a confounded factor: frequency of orthographic structure. As predicted, we reversed the word length effect when using short words with less frequent orthographic structures than the long words, as was done in both of Jalbert et al.’s studies. In Experiments 5 and 6, we again observed the typical word length effect, even if we controlled for neighborhood size and frequency of orthographic structure. Overall, the results were not consistent with the predictions of Jalbert et al. and clearly showed a large and reliable word length effect after controlling for neighborhood size.     

Shared Communities: A Multinational Qualitative Study of Immigrant and Receiving Community Members

Community psychology is central to understanding how immigrants and more established residents of their new settings join together to develop a shared sense of community and membership. In our present study, we explored how newer (i.e., first‐ and second‐generation immigrants) and more established community members form multiple positive psychological sense of community (PSOC) with one another. We conducted a multinational, qualitative study of PSOC through interviews with 201 first‐ and second‐generation immigrants and third generation or more “receiving community members” in three contexts (Baltimore‐Washington corridor of the U.S.; Torino, Italy; Lecce, Italy). Results indicated numerous similarities among the ways in which participants constructed PSOC in shared and nonshared communities, regardless of immigration/citizenship status, length of community residence, city, country, age, or gender. Small, proximal, and salient communities were often particularly important to building positive PSOC, which was formed around diverse membership boundaries. As intersectional beings, members converged and diverged on many characteristics, providing multiple opportunities for members to bring diversity to their communities while sharing other characteristics deemed essential to membership. Nonetheless, findings point to significant, structural challenges rooted in power and privilege that must be confronted to bridge the community‐diversity dialectic and build strong, shared sense of community.     

Resilience in Organ Transplantation: An Application of the Connor–Davidson Resilience Scale (CD–RISC) With Liver Transplant Candidates

End-stage liver disease (ESLD) is a chronic and debilitating condition associated with substantial psychological stress, morbidity, and mortality. The Connor–Davidson Resilience Scale (CD–RISC; Connor & Davidson, 2003 Connor, K. M., & Davidson, J. R. (2003). Development of a new resilience scale: The Connor– Davidson Resilience Scale (CD–RISC). Depression and Anxiety, 18(2), 76–82. doi:10.1002/da.10113[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) is a commonly used resilience measure. This research examined the validity of the CD–RISC among ESLD patients (N = 120) using exploratory factor analysis. Results supported a single-factor solution after removing poorly loading items. The CD–RISC also was correlated with measures of depression, anxiety, quality of life, social support, age, and cognitive ability, thus providing evidence to support its construct validity. Future research should confirm this factor structure and examine its predictive validity prior to widespread use among ESLD patients. This research represents the first step in this process and proposes an alternative version of the CD–RISC for this population.     

Incremental Validity of Leaderless Group Discussion Ratings Over and Above General Mental Ability and Personality in Predicting Promotion

Leaderless group discussions (LGDs) constitute one of the oldest assessment center exercises. In recent times, their added value has sometimes been questioned in light of trends to streamline assessment centers. The purpose of the present study is to examine the incremental validity of LGD ratings over cognitive ability scores and personality ratings for the prediction of extrinsic career success (i.e., promotion speed and number of promotions). We investigated this issue in the context of the promotion of French naval officers (N = 93) in an academy for high‐level executive positions over a 10‐year period. Results indicated that LGD ratings accounted for incremental variance in the prediction of promotion criterion measures, beyond cognitive ability and personality test scores. These results confirm that LGD ratings provide a unique contribution to the prediction of extrinsic career success in high‐level executive positions.
