confirmatory factor analysis of the dutch version of the wechsler Memory scale fourth edition wms iv nl
Archives of Clinical Neuropsychology, 2015Co-Authors: Zita Bouman, Marc P H Hendriks, Margreet C Kerkmeer, Roy P C Kessels, Albert P AldenkampAbstract:The latent factor structure of the Dutch version of the Wechsler Memory Scale-Fourth Edition (WMS-IV-NL) was examined with a series of confirmatory factor analyses. As part of the Dutch standardization, 1,188 healthy participants completed the WMS-IV-NL. Four models were tested for the Adult Battery (16-69 years; N = 699), and two models were tested for the Older Adult Battery (65-90 years; N = 489). Results corroborated the presence of three WMS-IV-NL factors in the Adult Battery consisting of Auditory Memory, Visual Memory, and Visual Working Memory. A two-factor model (consisting of Auditory Memory and Visual Memory) provided the best fit for the data of the Older Adult Battery. These findings provide evidence for the structural validity of the WMS-IV-NL, and further support the psychometric integrity of the WMS-IV.

Memory assessment and depression testing for factor structure and measurement invariance of the wechsler Memory scale fourth edition across a clinical and matched control sample
Journal of Clinical and Experimental Neuropsychology, 2013Co-Authors: Franz Pauls, Franz Petermann, Anja C LepachAbstract:Between-group comparisons are permissible and meaningfully interpretable only if diagnostic instruments are proved to measure the same latent dimensions across different groups. Addressing this issue, the present study was carried out to provide a rigorous test of measurement invariance. Confirmatory factor analyses were used to determine which model solution could best explain Memory performance as measured by the Wechsler Memory Scale–Fourth Edition (WMS–IV) in a clinical depression sample and in healthy controls. Multigroup confirmatory factor analysis was conducted to evaluate the evidence for measurement invariance. A three-factor model solution including the dimensions of auditory Memory, Visual Memory, and Visual working Memory was identified to best fit the data in both samples, and measurement invariance was partially satisfied. The results supported clinical utility of the WMS–IV—that is, auditory and Visual Memory performances of patients with depressive disorders are interpretable on the basis...

binding in short term Visual Memory
Journal of Experimental Psychology: General, 2002Co-Authors: Mary E Wheeler, Anne TreismanAbstract:The integration of complex information in working Memory, and its effect on capacity, shape the limits of conscious cognition. The literature conflicts on whether short-term Visual Memory represents information as integrated objects. A change-detection paradigm using objects defined by color with location or shape was used to investigate binding in short-term Visual Memory. Results showed that features from the same dimension compete for capacity, whereas features from different dimensions can be stored in parallel. Binding between these features can occur, but focused attention is required to create and maintain the binding over time, and this integrated format is vulnerable to interference. In the proposed model, working Memory capacity is limited both by the independent capacity of simple feature stores and by demands on attention networks that integrate this distributed information into complex but unified thought objects.

Visual Memory for novel shapes implicit coding without attention
Journal of Experimental Psychology: Learning Memory and Cognition, 1996Co-Authors: Brett G Deschepper, Anne TreismanAbstract:: Implicit Memory for novel shapes was explored with a negative priming paradigm. The results show that representations of shapes, formed in a single trial and without attention, can last without decrement across 200 intervening trials and with temporal delays of up to a month. No explicit Memory of the shapes was available, either immediately or after a delay. There were consistent individual differences in the amount of negative priming shown, and some participants showed only facilitation. There was a trend toward increased facilitation across time, as if the Memory of the shape survived longer than an "action tag" attached to it, which specified whether it should be attended or ignored. The results demonstrate a surprising combination of plasticity and permanence in the Visual system and suggest that the roles of both attention and repetition may be to ensure voluntary retrievability rather than to form a lasting Memory.
