Preservation of person‐specific knowledge in semantic memory disorder: A longitudinal investigation in two cases of dementia

The double dissociation involving person‐specific and general semantic knowledge is supported by numerous patient studies, though cases with preservation of the former are few. In this paper, we report longitudinal data from two cases. Their knowledge in both domains was preserved at the start of the investigation, but progressive deterioration was primarily observed on tests of general semantics. These data strengthen the evidence‐base for preservation of person‐specific knowledge in semantic memory disorder, and support its separate representation from object knowledge.

Multidimensional representation of objects—The influence of task demands

In our daily life, we often encounter situations in which different features of several multidimensional objects must be perceived simultaneously. There are two types of environments of this kind: environments with multidimensional objects that have unique feature associations, and environments with multidimensional objects that have mixed feature associations. Recently, we (Goldfarb & Treisman, 2013) described the association effect, suggesting that the latter type causes behavioral perception difficulties. In the present study, we investigated this effect further by examining whether the effect is determined via a feedforward visual path or via a high-order task demand component. In order to test this question, in Experiment 1 a set of multidimensional objects were presented while we manipulated the letter case of a target feature, thus creating a visually different but semantically equivalent object, in terms of its identity. Similarly, in Experiment 2 artificial groups with different physical properties were created according to the task demands. The results indicated that the association effect is determined by the task demands, which create the group of reference. The importance of high-order task demand components in the association effect is further discussed, as well as the possible role of the neural synchrony of object files in explaining this effect.     

Faking resistance of a quasi-ipsative RIASEC occupational interest measure

Quasi-ipsative (QI) forced-choice response formats are often recommended over single-stimulus (SS) as a method to reduce applicant faking. Across three studies we developed and tested a QI version of the RIASEC occupational interests scale. The first study established acceptable reliability and validity of the QI version. The second and third studies tested the efficacy of the QI version for faking prevention in simulated job applicant scenarios. The results revealed that although the QI and SS formats were similarly fakable for the primary targeted interest, faking was limited for the secondary target on the QI version. Future research should identify the specific contexts in which QI prevents faking on various individual differences measures to allow for accurate recommendations in applied settings.
