Increasing the probability of finding an interaction in work stress research: A two‐wave longitudinal test of the triple‐match principle

Research into work stress has attempted to identify job resources that can moderate the effects of job demands on strain. The recently developed triple‐match principle (TMP) proposes that job demands, resources, and strain can be conceptualized as being composed of cognitive, emotional, and physical dimensions. When a psychological imbalance is induced by job demands, individuals activate corresponding resources to reduce the effects of the demands. A closer match occurs when the resources are processed in the same psychological domain as the demands. The further away from a match, the less likely an interactive effect will become. Put simply, the likelihood of finding an interactive effect between job demands and job resources is greatest when demands, resources, and strain are based on qualitatively similar dimensions (i.e. cognitive, emotional, and physical). For example, emotional support from colleagues is likely to buffer the effects of emotional demands on emotional exhaustion. The TMP was tested in a sample of 179 Australian police officers in a two‐wave longitudinal study. The likelihood of finding an interactive effect was related to the degree of match between job demands, job resources, and strain with 33.3% of triple‐match interactions significant, 22.2% when there was a double‐match, and 0.0% when there was no match. These findings lend support to the TMP as a guiding framework, for research, to explore possible interactive effects in work stress research, and for practice, to inform interventions matching resources to occupational demands, to offset strain.     

Learning antecedents for anaphoric one

Lidz et al. [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't have learned: Experimental evidence for syntactic structure at 18 months. Cognition, 89, B65-B73.] claim experimental substantiation of an argument from the poverty of the stimulus, in the sense of Pullum and Scholz [Linguist. Rev. 19 (2002) 9]. They cite a specific feature of English--the assignment of appropriate antecedents for anaphoric one--that cannot possibly be learned from experience because the evidence needed is found only in utterances of a type too rare to be encountered. Their argument involves three empirical claims. In this note we dispute all three.     

The fundamental attribution error in detecting deception: the boy-who-cried-wolf effect

Most people are unable to detect accurately when others are lying. Many explanations for this inability have been suggested but the cognitive heuristics involved in lie detection have received little attention. The present study offers evidence from two experiments, based on two different groups of observers, judging two different kinds of lies, presented in two different testing situations, that the fundamental attribution error significantly undermines the ability to detect honesty and deception accurately. Trait judgments of trustworthiness were highly correlated with state judgments of truthfulness, leading, as predicted, to positive correlations with honest detection accuracy and negative correlations with deception detection accuracy. More accurate lie detectors were significantly more likely than less accurate lie detectors to separate state and trait judgments of honesty. The effect of other biases, such as the halo effect and the truthfulness bias, also are examined. Implications for future research and practice are discussed.     

Developmental outcome of drug-exposed children through 30 months: a comparison of Bayley and Bayley-II

This study examined the effects of the Bayley Scales of Infant Development (BSID) version on developmental outcomes among drug-exposed children, some of whom received an intervention. Developmental outcome was evaluated with the BSID at 12 and 18 months and with the BSID-II at 24 and 30 months. In the repeated measures analyses, children scored higher on the BSID Mental Developmental Index (MDI; p < .01) and Psychomotor Developmental Index (PDI; p < .01) than on the BSID-II MDI and PDI. Version x Time (p < .01) and Version x Group (p < .01) interactions were also found for the MDI but not the PDI. PDI scores decreased on both the BSID and the BSID-II (p < .01). Over the first 2 years postpartum, mean MDI and PDI scores decreased among these high-risk, drug-exposed children.     

Tracking Substance Abusers in Longitudinal Research: Understanding Follow-Up Contact Difficulty

Studies examining follow-up contact difficulty provide useful information for planning longitudinal studies and for assessing the validity of follow-up data. Contact difficulty was examined among 96 substance abusers following substance abuse treatment. Interview completion rates at the 3-month and 6-month follow-ups were 93 and 97%, respectively. The extent of contact efforts required to complete follow-up interviews varied substantially but tended to be greater at the 3-month follow-up than at the 6-month follow-up. Contact difficulty was related to reuse of substances at the 3-month and at the 6-month follow-ups with reusers requiring greater contact efforts than abstainers. None of the baseline individual and contextual variables examined significantly predicted level of contact effort at follow-ups. Attrition-related validity implications are discussed along with practical suggestions for planning tracking efforts.     

Using talking computers to remediate reading and spelling disabilities: The critical role of the print-to-sound unit

Talking computers employing computer-generated speech feedback have been used to remediate the literacy skills of dyslexic readers. A computer program is described that employs DECtalk, a highlevel speech synthesizer, to narrate instruction involving intensive training in identifying whole words or in identifying and blending word segments corresponding to onsets, rimes, and phonemes. Procedures for developing individualized instruction are described as well as for constructing and editing the speech and graphics features of the program. Neurologically impaired dyslexic children trained with this program achieved greater acquisition and transfer of word recognition skill when their training involved segmented rather than whole word feedback.
