Mother-child communication about location: giving and following directions for finding hidden objects.

We conducted 2 experiments to examine how mothers structure directions to young children for finding hidden objects and how young children use these directions to guide their searches. In Experiment 1, we examined the reference frames mothers use to communicate with their 2.5-, 3-, and 3.

Relationships among victoria symptom validity test indices and personality assessment inventory validity scales in a large clinical sample.

The purpose of this study was twofold: (1) to examine the relationships among measures of cognitive symptom exaggeration (i.e., response accuracy and response latency) and (2) to examine the relationship between measures of cognitive and psychopathological symptom exaggeration.

The latent structure of cognitive symptom exaggeration on the Victoria Symptom Validity Test.

Previous studies have focused on the ability of cognitive symptom validity tests to identify simulated malingering or distinguish between clinical samples of individuals at low or high risk of cognitive symptom exaggeration. However, no published studies have examined the latent structure of negative response bias on cognitive tests: measures of cognitive symptom exaggeration may evaluate a continuum of poor effort/invalid responding or a dichotomy of adequate versus inadequate effort. The present study examined whether Victoria Symptom Validity Test (VSVT) indices evaluate a latent dimension or category of response distortion.

Psychometric adequacy and comparability of the short and full forms of the Personality Assessment Inventory.

The 160-item short form of the Personality Assessment Inventory (PAI) was developed for situations in which respondents complete only the 1st half of the test. The present study evaluates the adequacy and comparability of the full and short forms of the PAI in terms of a wide range of psychometric characteristics. In all, 421 participants completed the full form as part of a neuropsychological evaluation.

Utility of the Boston naming test in predicting ultimate side of surgery in patients with medically intractable temporal lobe epilepsy.

Purpose: Confrontation naming tasks have long been presumed to be sensitive to left temporal dysfunction and, consequently, are frequently used in the evaluation of surgical epilepsy patients. Despite wide and frequent use, few studies have examined the utility of confrontation naming tasks in individuals with temporal lobe epilepsy (TLE).

Methods: The current study examined the presurgical Boston Naming Test (BNT) performance of 217 right-handed adult patients with intractable TLE (left, 108; right, 109) to determine the utility of this measure in predicting ultimate side of surgery.
