Predicting attitudes toward operation Iraqi freedom

98 male and female college students ranging in age from 17 to 22 years (M= 19.2, SD= 1.1) were administered a questionnaire that contained Altemeyer's 20-item Right-Wing Authoritarianism Scale (RWA), questions about the legitimacy of the 2000 presidential election, Mayton's Physical Nonviolence Subscale, and a scale designed to measure attitudes toward Operation Iraqi Freedom. RWA scores, perceptions of the legitimacy of the 2000 presidential election, and scores on the Physical Nonviolence subscale were independent predictors of attitudes toward Operation Iraqi Freedom. In addition, those who had higher RWA scores were more likely to perceive the 2000 presidential election as legitimate. There was no significant correlation between RWA scores and attitudes toward physical nonviolence.     

Comparison-induced decoy effects

Extant theories of decoy effects on evaluations of attribute values were assessed with respect to their ability to account for a one-dimensional analogue of the asymmetric dominance effect. Parducci's (1965, 1995) range-frequency theory, Krumhansl's (1978) distance-density model, Tversky's (1977) diagnosticity principle, and reference point theories (e.g., Holyoak & Mah, 1982) were unable to account for this effect. One version of Helson's (1964) adaptation-level theory and our comparison-induced distortion theory (Choplin & Hummel, 2002) were able to account for the qualitative effect. Quantitative fits revealed that comparison-induced distortion theory provides a better account of this effect than does adaptation-level theory. These results suggest that, in some cases, biases created by language-expressible magnitude comparisons mediate the effects of decoys on evaluation.     

Adolescent Psychopathy and Personality Theory—the Interpersonal Circumplex: Expanding Evidence of a Nomological Net

The construct validity of psychopathy was examined in a sample of 114 male and female young offenders (M_age = 15.16) at a southeastern detention center. The interpersonal circumplex served as a framework of general personality from which to examine the construct of adolescent psychopathy. A supplementary analysis of the psychopathy measures and the Big 5 factors of personality was also conducted using a matrix approach. Measures included: (a) Antisocial Process Screening Device (P. J. Frick & R. D. Hare, 2001); (b) Child Psychopathy Scale (D. R. Lynam, 1996); (c) Psychopathy Checklist—Youth Version (A. E. Forth, D. S. Kosson, & R. D. Hare, 2003); and (d) Interpersonal Adjective Scales Revised—Big 5 Version (P. Trapnell & J. S. Wiggins, 1991; J. S. Wiggins, 1995). Results showed substantial convergence among the three psychopathy measures. In addition, meaningful associations between psychopathy and constructs within the interpersonal circumplex and broader domains of the Big 5 were obtained. Two psychopathy scales correlated to a higher degree than expected with neuroticism. These findings provide evidence linking personality theory to the concept of child and adolescent psychopathy, thereby adding to its construct validity. However, they do so with the caveat that youth may also be displaying some characteristics of neuroticism, suggesting that worry and anxiety may accompany psychopathic features in earlier developmental stages. The implications of the current study are discussed.     

Prioritization of new objects in real-world scenes: evidence from eye movements

The authors examined the prioritization of abruptly appearing objects in real-world scenes by measuring the eyes' propensity to be directed to the new object. New objects were fixated more often than chance whether they appeared during fixations (transient onsets) or saccades (nontransient onsets). However, onsets that appeared during fixations were fixated sooner and more often than those coincident with saccades. Prioritization of onsets during saccades, but not fixations, were affected by manipulations of memory: Reducing scene viewing time prior to the onset eliminated prioritization, whereas prior study of the scenes increased prioritization. Transient objects draw attention quickly and do not depend on memory, but without a transient signal, new objects are prioritized over several saccades as memory is used to explicitly identify the change. These effects were not modulated by observers' expectations concerning the appearance of new objects, suggesting the prioritization of a transient is automatic and that memory-guided prioritization is implicit.     

Preview search and contextual cuing

We investigated the effect of contextual cuing (M. M. Chun & Y. Jiang, 1998) within the preview paradigm (D. G. Watson & G. W. Humphreys, 1997). Contextual cuing was shown with a 10-item letter search but not with more crowded 20-item displays. However, contextual learning did occur in a preview procedure in which 10 preview items were followed by 10 new items. Repeating the new items alone did not generate contextual learning, but repeating the preview items alone did, as long as they had a consistent spatial relation with the target. This was not merely due to the onset of the preview items being associated with the target location. No learning effect took place with a preview of homogeneous items that competed less for selection with new stimuli. The results provide evidence for old items being processed in preview search and providing a context for subsequent search of new items.     

Bi-phasic hitting with constraints on impact velocity and temporal precision

The aim of the experiment was to investigate how bi-phasic hitting movements are organized to comply with both impact and temporal precision constraints. 'Bi-phasic' refers to a sequential movement with a preparatory movement away from the interception location followed by a strike phase. The interception location was fixed, as the motion of the hitting device was constrained to follow a straight path orthogonal to that of the approaching balls. We manipulated the required temporal precision by projecting balls with different constant approach speeds (1, 1.5, and 2m/s). Different impact constraints were imposed by instructing participants first to simply hit the ball and subsequently to hit the ball to a designated target area located either 55 or 105 cm away from the interception location. We determined several kinematic variables and used Principal Component Factor Analysis to classify these variables. The analysis revealed two independent factors: a 'velocity' factor (formed by impact velocity, peak velocity of the preparatory phase, peak velocity of the strike phase, and amplitude of the strike) and a 'timing' factor (formed by onset of the preparatory phase, moment of peak velocity of the preparatory phase, and onset of the strike phase). The 'velocity' factor scaled significantly with the required impact constraint and the 'timing' factor scaled significantly with ball speed.     

Studies of Work: Achieving Hybrid Disciplines in IT Design and Management Studies

We explore the relationship between ethnomethodology (EM), ethnography and the needs of managers and designers in industry, considering both ethnomethodological and industrial criteria of adequacy and explicating their relationship through the concept of “audience.” We examine a range of studies in this light, with a view to their possible candidacy as hybrid studies and identify three types of application of EM studies of work: market research, design, and business improvement. Application in the first of these fields we dub “anthropological,” in that it consists in studying and reporting back on the ways of exotic people (customers). This is the application most commonly found in studies of computer supported co-operative work (CSCW). A second CSCW application, “technomethodology,” involves the introduction of EM concepts into the design process. A further application, dubbed “holding-up-a-mirror,” involves reporting back to members of a setting upon their own activities. We argue that technomethodology and holding-up-a-mirror both offer the possibility of creating hybrid disciplines. We consider the objection that improvement and design involve the introduction of value judgements that threaten the practice of EM indifference, arguing that action research can serve as a guarantee of unique adequacy (UA) by testing the researcher’s understanding as analysis in action in the setting. Furthermore, the standard of reporting required by the UA criterion contributes to the effectiveness of proposed solutions.     

Does retrieval fluency contribute to the underconfidence-with-practice effect?

Judgments of learning (JOLs) made during multiple study-test trials underestimate increases in recall performance across those trials, an effect that has been dubbed the underconfidence-with-practice (UWP) effect. In 3 experiments, the authors examined the contribution of retrieval fluency to the UWP effect for immediate and delayed JOLs. The UWP effect was demonstrated with reliable underconfidence on Trial 2 occurring for both kinds of JOL. However, in contrast to a retrieval-fluency hypothesis, fine-grained analyses indicated that the reliance of JOLs on retrieval fluency contributed minimally to the UWP effect. Our discussion focuses on the status of the retrieval-fluency hypothesis for the UWP effect.     

Eye gaze and individual differences consistent with learned attention in associative blocking and highlighting

The associative learning effects called blocking and highlighting have previously been explained by covert learned attention, but evidence for learned attention has been indirect, via models of response choice. The present research reports results from eye tracking consistent with the attentional hypothesis: Gaze duration is diminished for blocked cues and augmented for highlighted cues. If degree of attentional learning varies across individuals but is relatively stable within individuals, then the magnitude of blocking and highlighting should covary across individuals. This predicted correlation is obtained for both choice and eye gaze. A connectionist model that implements attentional learning is shown to fit the data and account for individual differences by variation in its attentional parameters.
