Seven experiments were conducted to examine the role of attention in automatization. Ss searched 2-word displays for members of a target category in divided-attention, focused-attention, and dual-task conditions. The main issue was whether attention conditions would affect what Ss learned about co-occurrences of the words in the displays. The attention(More)
The instance theory of automaticity claims that people learn what they attend to and express what they learned in transfer if they attend to the same things in the same way. These hypotheses were tested in 8 category search experiments in which target position was cued by color (red or green). The main question was whether target color would be encoded in(More)
BACKGROUND CONTEXT Pain patients often report cognitive symptoms, and many will include them in their claims of disability. There is empirical evidence that patients with pain do experience problems on attention-demanding cognitive tasks, but the results are mixed and the potential impact of exaggeration in the context of pain-related litigation has not(More)
Pain patients often report cognitive symptoms and many will include them in their claims of disability. The Processing Speed Index (PSI) of the WAIS-III was investigated as one aspect of cognitive functioning in six groups. Slight impairment was found for PSI and Digit Symbol subtest performance, but not for Symbol Search, in a Laboratory-induced Pain group(More)
This study used criterion groups validation to determine the accuracy of the Test of Memory Malingering (TOMM) in detecting malingered pain-related disability (MPRD) across a range of cutoffs in chronic pain patients undergoing psychological evaluation (n = 604). Data from patients with traumatic brain injury (n = 45) and dementia (n = 59) are presented for(More)
The purpose of this study was to determine the accuracy of Minnesota Multiphasic Personality Inventory 2nd edition (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) validity indicators in the detection of malingering in clinical patients with chronic pain using a hybrid clinical-known groups/simulator design. The sample consisted of patients(More)
The Test of Memory Malingering (TOMM) is a well-validated and widely used forced-choice symptom validity test. However, little is known about how TOMM performance is affected by pain. The present study evaluated the sensitivity of the TOMM to pain induced in healthy participants via the cold-presser test. Participants (n=20 per group) were administered the(More)
This study used criterion groups validation (known-groups design) to examine the classification accuracy of the Reliable Digit Span test (RDS) in a large group of chronic pain patients referred for psychological evaluation. The sample consisted of 612 patients classified into one of six groups based on evidence of malingered pain-related disability (MPRD):(More)
Reliable Digit Span (RDS) is an indicator used to assess the validity of cognitive test performance. Scores of 7 or lower suggest poor effort or negative response bias. The possibility that RDS scores are also affected by pain has not been addressed thus potentially threatening RDS specificity. The current study used cold pressor-induced pain to investigate(More)
