Specific word transfer as a measure of processing in the word-superiority paradigm

Explanations of context effects in the Reicher-Wheeler task and the letter-identification task appeal to word-based processing, yet these tasks provide no explicit measure of word processing. An experiment is reported which was designed to investigate the use of transfer in the word-identification task as a measure of word-based processing in letter-identification tasks. It was found that encoding manipulations that determined whether a word-superiority effect was or was not found in a letter-identification task (e.g., Thompson & Massaro, 1973) also determined whether transfer was or was not found in a subsequent word-identification task. The results of the experiment are discussed in terms of the utility of using transfer experiments as converging evidence about the presence and/or absence of processes that cannot be directly measured in other experimental paradigms.     

Field reliability of comprehensive system scoring in an adolescent inpatient sample

The extent to which the Comprehensive System for the Rorschach is reliably scored has been a topic of some controversy. Although several studies have concluded it can be scored reliably in research settings, little is known about its reliability in field settings. This study evaluated the reliability of both response-level codes and protocol-level scores among 84 adolescent psychiatric inpatients in a clinical setting. Rorschachs were originally administered and scored for clinical purposes. Among response codes, 87% demonstrated acceptable reliability(> .60), and most coefficients exceeded .80. Results were similar for protocol-level scores, with only one score demonstrating less than adequate reliability. The findings are consistent with previous evidence, indicating reliable scoring is possible even in field settings.     

Offender interviewing in custodial settings: Understanding validity,value and veracity issues

The purpose of this scoping literature review was to identify trends regarding validity, value and veracity issues when conducting (qualitative) interviews with offenders in custodial settings. We selected for review works from electronic databases in SAGE, Springer, and Taylor and Francis by using e-journals, Google Scholar and the behavioural science database, PsycINFO. The inclusion criteria for our studies were based on whether sources addressed offender interviewing as a wellspring of information, but excluded those that focused solely on the acquisition of clinical information (at the expense of focusing on validity, value and veracity issues). We utilised the content analysis approach to identify themes/ patterns in the research findings. Key findings suggest that offenders with impression management motivations deceive and manipulate in their research interview presentations. When gathering data from inmates in custodial care settings, best practice includes cross-checking offender interview data against other sources of evidence and taking into account the context in which they are serving their sentences.     

Stochastic independence in the recognition/identification paradigm

Abstract

Experiments in which subjects study a set of items and then take two successive tests, a recognition test followed by a test of implicit retrieval of the same items (e.g. Tulving, Schacter, & Stark, 1982), have typically yielded data showing stochastic independence between the tests. Ostergaard (1992) has suggested that the procedure for assessing such independence should include an evaluation of the data against a model that assumes maximal dependence between the components of the test attributable to the study episode. In applying his Maximum Memory Dependence model to the published data, however, Ostergaard inexplicably used test-primed data for baseline measures, rather than non-primed data, and erroneously concluded that there was no clear evidence for independence. In this article, we show that when the standard baseline measures are used, the results of many experiments demonstrate stochastic independence.     

On the measurement of priming: What is the correct baseline?

Abstract

We argue, contrary to Ostergaard (this issue), that the baseline for measuring priming effects in “recognition/identification” experiments is correctly estimated by the subjects’ performance with non-primed items. There is no reason to assume, as Ostergaard (this issue) does, that priming that occurs in a single presentation of the target item is qualitatively different from priming that occurs, in the same experimental situation, in two or more presentations, or that empirical findings, such as stochastic independence between recognition and primed identification, are affected by the number of presentations of the target items at study.     

A comparison of MMPI-2 high-point coding strategies

High-point coding refers to the popular practice of classifying Minnesota Multiphasic Personality Inventory (Hathaway & McKinley, 1983) profiles based on which clinical scales are the most elevated. A previous review of high-point code studies (McGrath & Ingersoll, 1999a) noted marked discrepancies across studies in the rules used to define high-point codes. This study was conducted to evaluate the costs and benefits of different strategies for high-point coding. The impact of 4 rules for high-point coding on effect sizes and group sizes was evaluated. The 4 rules included requiring a minimum elevation, excluding potentially invalid protocols, restricting coding to well-defined codes, and replacing the lower scale in infrequently occurring codes with the next most elevated scale. The evidence supported the clinical utility of requiring a minimum elevation for code scales. The results were more equivocal concerning the value of well-defined coding and for not replacing the lower scale in infrequent codes. Results were surprisingly negative concerning the utility of excluding potentially invalid protocols, suggesting that guidelines developed in situations in which there is a clear motivation to distort results may not generalize to other settings.     

Perceptual identification of visually degraded stimuli

In this article, we describe procedures, materials, and some representative results of a microcomputer-based approach to the degradation of visual stimuli for the investigation of perceptual identification. We discuss application of the procedures for the production of visually degraded picture, letter, and word stimuli, and of visual stimuli common to neuropsychological investigations.     

Contingent dissociation between recognition and fragment completion: the method of triangulation

Two experiments conforming to the logic of the method of triangulation were conducted. Following the study of a list of words, the first of two successive tests (recognition) was identical for two groups of subjects, but the second one, in which the same word-fragment cues were presented to both groups, differed with respect to retrieval instructions. Subjects in one group engaged in cued recall of study-list words, whereas those in the second group completed the fragments with the first word that came to mind. Both experiments yielded the same result: The dependency between the first and second tests, indexed by Yule's Q statistic, was greater for recognition and cued recall than it was for recognition and fragment completion. These results speak to the controversial issue of the usefulness of contingency analyses of data from successive memory tests. The results are interpreted in a theoretical framework consisting of an integration of the idea of a hypothetical quasi-memory system with the transfer-appropriate procedural approach.
