The moderating effect of need type on the prediction of overall job satisfaction

Recent investigations concerned with the analysis of work motivation and job satisfaction constructs have combined the logic of subgrouping with an emphasis on the importance of individual differences. The present study is based on a need-fulfillment model, which places a major emphasis on individual differences in needs. A hierarchical clustering method was used to subgroup a sample of 570 managers on their need profiles. Need type was tested as a moderator of the relationship between specific dimensions of job satisfaction and overall job satisfaction. The findings showed that need type moderated the relative contributions of specific dimensions of satisfaction in the prediction of overall job satisfaction, and in addition the prediction level was found to be greater for the need types than for the total sample.     

Dimensions of perception of posture in dance

This study reports a preliminary investigation designed to assess the possibility of using a semantic differential in the appraisal of expressive characteristics of posture in dance.Twenty still photographs of postures displayed by one female dancer were judged on 25 bipolar scales by 50 Ss. Ratings of eight of these Ss were used for estimating reliabilities of the scales — resulting in elimination of five scales. Intercorrelation matrices of the 20 remaining scales were obtained for each of the 42 remaining Ss. Consideration of homogeneity of the distribution of these matrices led to the exclusion of four of them, leaving 38 matrices for further analysis.After random division of these matrices into two equally sized subgroups, principal component analyses with VARIMAX rotation were carried out on the average intercorrelation matrix for each subgroup. This resulted in two very similar three-factor solutions. The three factors, identified as similar to Osgood's well-known factors of activity, evaluation and potency, accounted for about 55% of the total variance. The results, discussed in terms of Berlyne's conception, suggest that the semantic differential may be a reliable instrument for measuring connotations of posture in dance.     

Phonological and semantic priming: Evidence for task-independent effects

The questions asked in the present experiments concern the generality of semantic and phonological priming effects: Do these effects arise automatically regardless of target task, or are these effects restricted to target tasks that specifically require the retrieval of the primed information? In Experiment 1, subjects produced faster color matching times on targets preceded by a masked rhyming prime than on targets preceded by an orthographic control or an unrelated prime. This result suggests that automatic priming effects on the basis of phonological similarity can be obtained even when the target task does not make use of phonological information. This claim was reinforced in Experiment 2 in which a rhyme priming effect and a semantic priming effect were found in a semantic categorization task. In Experiment 3, the target task was phonological (rhyme detection), and, again, both phonological and semantic priming effects were observed. Finally, in Experiments 4 and 5, in a replication and an extension of Experiment 1, phonological and semantic priming effects were found in a color matching task, a task involving neither phonological nor semantic processing. These results are most straightforwardly interpreted by assuming that both semantic and phonological priming effects are, at least in part, due to automatic activation of memorial representations.     

A FORMULA FOR THE USE OF SUPPRESSION VARIABLES IN CORRECTING INDIVIDUAL RATINGS

D unér , A. & M agnusson , D. A formula for the use of suppression variables in correcting individual ratings. Scand. J. Psychol , 1962, 3 , 226–232.—Ratings of aptitude, ability or performance used for selection and/or prediction or as criteria for the estimation of the validity of other methods are often influenced by irrelevant factors. Two correction formulas based on a suppression variable have been derived. The relation between the correlation formula derived and the partial correlation formula is discussed, as well as the effect of the application of the formula on the estimation of differential validity.     

Repeated interrogations: verbal and non‐verbal cues to deception

The major aim of this study was to investigate to what extent verbal and non‐verbal features of liars' and truth‐tellers' behaviour change during the course of repeated interrogations. After seeing a staged event, 24 suspects (12 liars and 12 truth‐tellers) were interrogated three times over a period of 11 days. In terms of the non‐verbal features, and in line with our prediction, we found that the liars displayed significantly fewer smiles, self‐manipulations, pauses, and less gaze aversion than truth‐tellers. Furthermore, over time the initial differences between liars' and truth‐tellers' non‐verbal behaviour increased for smiles, gaze aversion and pauses. In addition, we found that the cue ‘richness of detail’—the most indicative verbal marker for truth as given in previous research—had no discriminative power at any of the interrogation sessions. Finally, and in contrast to beliefs held by supposed expert lie‐catchers (e.g. judges and police officers), truthful and deceptive statements were found to be equally consistent over time. The psycho‐legal implications of the above findings are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

What is embodiment? A psychometric approach

What is it like to have a body? The present study takes a psychometric approach to this question. We collected structured introspective reports of the rubber hand illusion, to systematically investigate the structure of bodily self-consciousness. Participants observed a rubber hand that was stroked either synchronously or asynchronously with their own hand and then made proprioceptive judgments of the location of their own hand and used Likert scales to rate their agreement or disagreement with 27 statements relating to their subjective experience of the illusion. Principal components analysis of this data revealed four major components of the experience across conditions, which we interpret as: embodiment of rubber hand, loss of own hand, movement, and affect. In the asynchronous condition, an additional fifth component, deafference, was found. Secondary analysis of the embodiment of runner hand component revealed three subcomponents in both conditions: ownership, location, and agency. The ownership and location components were independent significant predictors of proprioceptive biases induced by the illusion. These results suggest that psychometric tools may provide a rich method for studying the structure of conscious experience, and point the way towards an empirically rigorous phenomenology.     

The Variety of Lattice Effect Algebras Generated by MV-algebras and the Horizontal Sum of Two 3-element Chains

It has been recently shown [4] that the lattice effect algebras can be treated as a subvariety of the variety of so-called basic algebras. The open problem whether all subdirectly irreducible distributive lattice effect algebras are just subdirectly irreducible MV-chains and the horizontal sum of two 3-element chains is in the paper transferred into a more tractable one. We prove that modulo distributive lattice effect algebras, the variety generated by MV-algebras and is definable by three simple identities and the problem now is to check if these identities are satisfied by all distributive lattice effect algebras or not.

Keeping the Spirit of Community Partnerships Alive in the Scale Up of HIV/AIDS Prevention: Critical Reflections on the Roll Out of DEBI (Diffusion of Effective Behavioral Interventions)

DEBI, or the Diffusion of Effective Behavioral Interventions is the largest centralized effort to diffuse evidence-based prevention science to fight HIV/AIDS in the United States. DEBI seeks to ensure that the most effective science-based prevention interventions are widely implemented across the country in community-based organizations. Thus, this is a particularly timely juncture in which to critically reflect on the extent to which known principles of community collaboration have guided key processes associated with the DEBI rollout. We review the available evidence on how the dissemination of packaged interventions is necessary but not sufficient for ensuring the success of technology transfer. We consider additional principles that are vital for successful technology transfer, which were not central considerations in the rollout of the DEBI initiative. These issues are: (1) community perceptions of a top-down mode of dissemination; (2) the extent to which local innovations are being embraced, bolstered, or eliminated; and (3) contextual and methodological considerations that shape community preparedness. Consideration of these additional factors is necessary in order to effectively document, manage, and advance the science of dissemination and technology transfer in centralized prevention efforts within and outside of HIV/AIDS.     

The ‘elasticity’ of criminal evidence: a moderator of investigator bias

This study examined investigators' perceptions of the reliability of incriminating and exonerating evidence of different types. Police trainees in the role of investigators read the background of a homicide case and then received a piece of evidence that either confirmed or disconfirmed their prior suspicion against the suspect. Despite identical objective characteristics of the evidence, participants rated the disconfirming (vs. confirming) evidence as less reliable and generated more arguments to question its reliability. This asymmetrical scepticism was stronger for participants judging witness evidence, compared to DNA and photo evidence, supporting the hypothesis that different types of evidence vary in ‘elasticity’—the extent to which subjective interpretations can be justified. Interestingly, the observed effects were not limited to the specific evidence in the case, but also affected the ratings of the type of evidence in general, suggesting that reliability criteria for witness information are highly malleable and sensitive to contextual influences.

Internet‐initiated sexual abuse: adolescent victims' reports about On‐ and Off‐line sexual activities

The purpose of the present study was to investigate how adolescent girls, who had been sexually (on‐ and off‐line) deceived and abused by an Internet hebephile, reported about these acts. As we had access to documentation of 68 girls' conversations (i.e. chat logs) and involvement with the perpetrator, we were able to gauge what the victims reported during the police interview against this detailed documentation. In contrast with findings from previous research, the majority of victims reported about the off‐line activities (real‐life meetings) with the perpetrator. However, the victims omitted and/or denied more of the on‐line activities, specifically the more severe sexual on‐line acts (sending nude photos and participating in sexual web shows). There is probably a gap between what the victims reported and what they presumably remembered about the on‐line activities. Factors that might have affected the victims' pattern of reports are discussed. Copyright © 2008 John Wiley & Sons, Ltd.
