Beyond category sorting and pleasantness rating: Inducing relational and item-specific processing

In most studies of relational and item-specific processing, category sorting and pleasantness rating have been the main procedures used to induce these two types of processing. Because the two types of processing have been studied in a wide range of memory phenomena (Hunt & McDaniel, 1993), it is strange that other tasks have not been proposed and tested. The present experiment demonstrates that equivalent results can be obtained with three relational processing tasks (category sorting, narrative construction, and relational imagery) and equivalent results with three itemspecific processing tasks (pleasantness ratings, familiarity ratings, and single imagery).

Failure to replicate a QTL association between a DNA marker identified by EST00083 and IQ

In a paper published in this journal, a possible QTL association was reported between general cognitive ability and a marker, identified by an expressed sequence tag, EST00083 (Skuder et al., 1995). In two small samples, the frequency of the common allele of this DNA marker, which was shown to be in the threonine transfer RNA gene in mitochondrial DNA, was significantly greater in a high-IQ group than in a low-IQ group. As part of the ongoing IQ QTL Project (Plomin et al., 1995), we have attempted to replicate this QTL association. First, we found that the QTL association remained significant when we compared 51 high- and 51 -average IQ subjects, drawn in part from the samples used in the previous report. However, when we examined the association in new samples of 40 extremely high-IQ subjects and 50 average-IQ subjects, the association did not replicate. This underlies the need for replication in case-control studies of allelic association.     

A comparative study of scales constructed by three psychophysical methods

A comparison is made between the scales constructed by the Method of Paired Comparison, Rank Order, and the Method of Successive Intervals. Application of the three psychophysical methods to handwriting specimens and to nationality preferences results in mutually linear scales. Choice of scaling methods becomes, then, a matter of practical convenience rather than of relative validity.The writer is very much indebted to Professor L. L. Thurstone for the suggestion of this problem and for supervision in carrying out the study.     

Case Groups: An In-Service Education Technique

An elementary public school utilized Case Groups as part of a comprehensive in-service education program for its staff. The Case Group was designed as a paced learning experience incorporating elements from discussion, case study, and sensitivity training groups in the attempt to facilitate both cognitive and experiential aspects of the teachers' continuing professional growth. The kinds of growth experienced by the participants are described and subjectively evaluated to the conclusion that the Case Group, or modifications thereof, has high potential for the in-service education of teachers.     

Altered emotional decision-making in prisoners with borderline personality disorder

Previous studies have identified neuropsychological deficits in individuals with antisocial personality disorder and/or psychopathy. Few studies have examined neuropsychological functioning in individuals with borderline personality disorder (BPD), and no studies have yet investigated cognitive and emotional function in male prisoners with BPD. In this study, we compared the risky decision-making of 17 participants with a history of serious violent or sexual offenses and a diagnosis of DSM-IV BPD with that of 17 participants with similar offending histories but personality disorders other than BPD. Those with BPD exhibited altered processing of information about potential losses (punishment) when the probability of gains (reward) was high; they also increased their choice of risky options even in circumstances where this was clearly avoidable. These data suggest that individuals with a diagnosis of BPD and a history of serious offenses have problems integrating different reinforcement signals when choosing between risky actions, perhaps reflecting corticolimbic dysfunction as an underlying mechanism in BPD.     

Assessing the multidimensional and hierarchical structure of SERVQUAL

Parasuraman, Zeithaml, and Berry introduced SERVQUAL in 1998 as a scale to measure service quality. Since then, researchers have proposed several variations. This study examines the development of the tool. Marketing researchers have first challenged the conceptualization of a perceptions-expectations gap and have concluded that the performance-based measures are adequate to capture consumers' perception of service quality. Some researchers have argued that the five dimensions of the SERVQUAL scale only focus on the process of service delivery and have extended the SERVQUAL scale into six dimensions by including the service outcome dimension. Others have proposed that service quality is a multilevel construct and should be measured accordingly. From a sample of 467 undergraduate students data on service quality toward up-scale restaurants were collected. Using the structural equation approach, two measurement models of service quality were compared, the extended SERVQUAL model and the restructured multilevel SERVQUAL model. Analysis suggested that the latter model fits the data better than the extended one.     

Three-year outcomes of exposure to a science curriculum

From 1,142 seventh and eighth graders responses to paper-and-pencil measures were correlated with scores on a science-based antismoking curriculum and on tobacco use behavior (-.14 to -.24).     

The influence of stimulus properties on category construction

It has been demonstrated that when people free classify stimuli presented simultaneously in an array, they have a preference to categorize by a single dimension. However, when people are encouraged to categorize items sequentially, they sort by "family resemblance," grouping by overall similarity. The present studies extended this research, producing 3 main findings. First, the sequential procedure introduced by G. Regehr and L. R. Brooks (1995) does not always produce a preference for family resemblance sorts. Second, sort strategy in a sequential procedure is sensitive to subtle variations in stimulus properties. Third, spatially separable stimuli evoked more family resemblance sons than stimuli of greater spatial integration. It is suggested that the family resemblance sorting observed is due to an analytic strategy.
