Teaching Children with Autism Spectrum Disorder to Mand “Where?”

A modified multiple-baseline design across participants was used to evaluate a procedure for teaching the mand “Where?” to 3 children with autism. The participants were 3 and 5?years old and were participating in an intensive applied behavior analysis program. The participants were able to mand for items they wanted when the items were not in sight but were unable to ask where an item was located. The procedure consisted of a preference assessment for play activities, contrived conditioned motivating operations (CMO’s), prompting the children to mand “Where,” and consequences for correct and incorrect responding. Each contrived CMO consisted of an opportunity for the child to mand “Where” while playing with a selected activity, prompting the child to mand, and reinforcing a correct response by answering the question “Where.” Two of the participants learned to mand “Where” after training with 1 CMO and the mand generalized to novel contrived situations, activities, and the natural environment and was maintained over time (up to 4-weeks), whereas one participant required training with a second CMO before generalization occurred.

Person–organization fit effects on organizational attraction: A test of an expectations-based model

This study investigates the mechanisms that explain why person–organization (PO) fit impacts organizational attraction. Adopting Edwards and Cable’s (2009) approach, an integrative model is developed around the idea that experiencing value congruence during the recruitment process perpetuates certain expectations about future work environments and employer relationships. These expectations in turn have a positive impact on organizational attraction. Evidence from a longitudinal study on a sample of job seekers suggests that expected opportunities for value expression and need fulfillment offered the most viable explanations of value congruence effects. The implications of important observed differences in the experience of PO fit between job seekers and full-time employees are discussed.     

Reply to Rouder (2014): Good frequentist properties raise confidence

Established psychological results have been called into question by demonstrations that statistical significance is easy to achieve, even in the absence of an effect. One often-warned-against practice, choosing when to stop the experiment on the basis of the results, is guaranteed to produce significant results. In response to these demonstrations, Bayes factors have been proposed as an antidote to this practice, because they are invariant with respect to how an experiment was stopped. Should researchers only care about the resulting Bayes factor, without concern for how it was produced? Yu, Sprenger, Thomas, and Dougherty (2014) and Sanborn and Hills (2014) demonstrated that Bayes factors are sometimes strongly influenced by the stopping rules used. However, Rouder (2014) has provided a compelling demonstration that despite this influence, the evidence supplied by Bayes factors remains correct. Here we address why the ability to influence Bayes factors should still matter to researchers, despite the correctness of the evidence. We argue that good frequentist properties mean that results will more often agree with researchers’ statistical intuitions, and good frequentist properties control the number of studies that will later be refuted. Both help raise confidence in psychological results.     

The role of partial knowledge in statistical word learning

A critical question about the nature of human learning is whether it is an all-or-none or a gradual, accumulative process. Associative and statistical theories of word learning rely critically on the later assumption: that the process of learning a word’s meaning unfolds over time. That is, learning the correct referent for a word involves the accumulation of partial knowledge across multiple instances. Some theories also make an even stronger claim: Partial knowledge of one word–object mapping can speed up the acquisition of other word–object mappings. We present three experiments that test and verify these claims by exposing learners to two consecutive blocks of cross-situational learning, in which half of the words and objects in the second block were those that participants failed to learn in Block 1. In line with an accumulative account, Re-exposure to these mis-mapped items accelerated the acquisition of both previously experienced mappings and wholly new word–object mappings. But how does partial knowledge of some words speed the acquisition of others? We consider two hypotheses. First, partial knowledge of a word could reduce the amount of information required for it to reach threshold, and the supra-threshold mapping could subsequently aid in the acquisition of new mappings. Alternatively, partial knowledge of a word’s meaning could be useful for disambiguating the meanings of other words even before the threshold of learning is reached. We construct and compare computational models embodying each of these hypotheses and show that the latter provides a better explanation of the empirical data.

A Cross-Language Study of Perception of Lexical Stress in English

This study investigates the question of whether language background affects the perception of lexical stress in English. Thirty native English speakers and 30 native Chinese learners of English participated in a stressed-syllable identification task and a discrimination task involving three types of stimuli (real words/pseudowords/hums). The results show that both language groups were able to identify and discriminate stress patterns. Lexical and segmental information affected the English and Chinese speakers in varying degrees. English and Chinese speakers showed different response patterns to trochaic vs. iambic stress across the three types of stimuli. An acoustic analysis revealed that two language groups used different acoustic cues to process lexical stress. The findings suggest that the different degrees of lexical and segmental effects can be explained by language background, which in turn supports the hypothesis that language background affects the perception of lexical stress in English.
