Loss of Financial Capacity in Alzheimer's Disease: The Role of Working Memory

Recent research has demonstrated that loss of financial capacity is a common consequence of Alzheimer's disease (AD). While progressive cognitive decline is a defining feature of AD, the relationship between such decline and loss of financial capacity in AD remains unclear. Working memory may be strongly associated with financial abilities, as many financial tasks require temporary storage and manipulation of numerical and other data. The present study examined the relationship between financial capacity and working memory in AD patients. Participants included 20 AD patients and 23 cognitively intact older controls. Working memory was conceptualized using Baddeley and colleagues' model, which posits that the three components of the working memory system are the visuospatial sketchpad, phonological loop, and central executive system. The present study examined only the latter two components of working memory. Each participant was administered the Financial Capacity Instrument (FCI), an instrument that directly assesses eight domains of financial activity, and the WAIS-III Working Memory subtests (Digit Span, Arithmetic, Letter–Number Sequencing). AD patients as a group performed significantly below controls on the FCI Total Score and on each of the eight FCI domains and working memory subtests. Within the AD group, measures of the central executive component of working memory (WAIS-III Digits Backward, Arithmetic, and Letter-Number Sequencing tests) showed strong correlations with the FCI domains of basic monetary skills, checkbook management, bank statement management, and bill payment and FCI total score, while a measure of the phonological loop component of working memory (WAIS-III Digits Forward) was not significantly correlated with any FCI domains or with the FCI total score. The results suggest that the multiple domains of financial capacity are primarily correlated with the central executive component of working memory.     

Personality Assessment Inventory profiles of deployed combat troops: an empirical investigation of normative performance

The present study examined the normative scores and psychometric properties of the Personality Assessment Inventory (PAI; Morey, 1991) within a non-treatment-seeking sample of soldiers deployed to combat zones in Iraq, compared with a sample of community adults matched with respect to age and gender. Results indicate the scores and properties of the PAI scales were generally quite similar in the Iraq and community samples, with modest differences emerging on only 3 subscales addressing antisocial behavior, issues with close relationships, and interpersonal vigilance. These results suggest that standard normative interpretation of PAI scales is appropriate even when the instrument is administered in a combat zone. In comparison with prior research, the results may suggest that documented mental health issues among combat veterans, when present, may be particularly likely to emerge postdeployment.     

DataVision: A computer-based system for generating and reading digital information accompanying video images on videotape

An Apple IIe-based system is described that generates both machine-readable and human-readable numbers for recording with visual information on videotape. Hardware and software components of the encoding system are detailed. An automatic decoding system that reads the numbers from videotape into computer memory is also described. Current applications of the system are briefly discussed.     

Evaluating the quality of training delivered by direct-care staff in a state mental retardation center

This study evaluated a center-wide training system in a state-operated mental retardation center. Staff performance was assessed under varying conditions with collateral measures collected on resident behavior. The quality of training delivered by direct-care staff was measured following the completion of an inservice training program and when individual feedback and praise were available or a group contingency where feedback, praise, and money were available. Inservice training was not found to be sufficient to maintain staff training skills. Providing feedback and praise had mixed results in maintaining staff behavior. A group contingency using feedback, praise, and money was found to be immediately effective in improving and maintaining staff behavior. Collateral measures on student behavior were also provided that indicated that consistent, quality training by staff resulted in increased student skill acquisition. These results are discussed within the framework of conducting research in applied settings.     

An improved video multiplexer for behavioral research

Wellens and Revert (1979) described a solid-state circuit that allowed two sources of video information to be multiplexed and recorded using one videotape machine. On playback, the demultiplexed video signal allowed the original video channels to be viewed independently on separate television monitors. Recent changes in videocassette recorder technology have improved the playback quality of recorded images but disrupt the demultiplexing process when freeze frame or search options are selected. Improved multiplexing techniques that overcome these limitations are described.

Validation of an automated 16PF administration procedure

Examined the effects of a computer-based administration procedure on reliability and validity of a personality questionnaire. Utilizing a counterbalanced repeated-measures design, Form A of the 16PF was administered to 80 undergraduates who had been randomly assigned to either computer-computer, computer-booklet, booklet-computer, or booklet-booklet administration conditions. Subjects also completed a self-report anxiety measure before and after each administration of the 16PF. Multivariate analyses revealed no significant differences in score reliability, validity, or self-reported anxiety among the four administration conditions. Small yet significant differences were noted with respect to ratings of the assessment experience. Subjects in the two groups which were exposed to both administration formats rated the computer procedure as more positive in comparison to the booklet format. Due to the student sample, replication of these findings with treatment-seeking clients is needed.
