Stability of daily preference across multiple individuals

Preference stability provides clues about the extent to which a clinician might be able to deliver a particular stimulus contingent on behavior as a reinforcer. Previous research has been somewhat mixed in terms of evidence for preference stability. Results of the current study are consistent with studies that have reported correlations between preference assessments, suggesting that preferences are relatively stable across time.     

Validation of a Chinese Version of the Psychological Sense of School Membership (C-PSSM): Tests of Measurement Invariance and Latent Mean Differences

This study examined the factorial structure of the Chinese version psychological sense of school membership scale (C-PSSM) (Cheung and Hui Asia Pacific Education Review, 4(1), 67–74, 2003). Five hundred and thirty-four university students from Hong Kong completed an 18-item C-PSSM and data were analyzed using exploratory factor analysis and confirmatory factor analysis. In addition, tests of measurement invariance and latent mean differences were performed. From the results of the CFA, two items were deleted and a 3-factor, 16-item C-PSSM model was found to have an acceptable fit, with acceptable level of internal consistency for each factor and the overall scale. Measurement invariance (configural, metric, and partial scalar) of the 16-item C-PSSM was supported and the tests of latent mean differences revealed no statistical significance in factor score differences between male and female participants in this study. Overall, this study contributed to the literature by generating new insights on to the psychological sense of school membership through validating the C-PSSM on a sample from a culture and age group different from those reported in the current literature.     

A Guide to Conducting a Meta-Analysis

Meta-analysis is widely accepted as the preferred method to synthesize research findings in various disciplines. This paper provides an introduction to when and how to conduct a meta-analysis. Several practical questions, such as advantages of meta-analysis over conventional narrative review and the number of studies required for a meta-analysis, are addressed. Common meta-analytic models are then introduced. An artificial dataset is used to illustrate how a meta-analysis is conducted in several software packages. The paper concludes with some common pitfalls of meta-analysis and their solutions. The primary goal of this paper is to provide a summary background to readers who would like to conduct their first meta-analytic study.     

Increasing Single‐Word Requests to Multiword Requests in Children with Autism and Related Disabilities

Initial language training with children with autism often focuses on the production of single‐word requests (i.e., mands). As a child progresses in treatment, it is desirable to increase the mean length of utterance (MLU) of requests. The present study examined treatment outcomes of behavioral intervention designed to increase the MLU of requests in a larger sample of children with language delays (n = 30). Intervention consisted of prompts and differential reinforcement for lengthier requests, and trials were conducted flexibly throughout the treatment session. A non‐concurrent multiple baseline across participants design was utilized to establish experimental control, and MLU intervention consisted of a baseline and treatment phase for each participant. Nonoverlap of all pairs (NAP) was employed to estimate an effect size. Overall treatment effects were medium to large (average NAP = 0.89; average d = 2.36), and the majority of the sample (70%) demonstrated strong treatment effects. Results suggest that targeted behavioral intervention to increase the length of requests can be effective for children with autism and associated language delays.

Maternal Child‐rearing Practices in Hong Kong and Beijing Chinese Families: A Comparative Study

The present study aimed to examine the child‐rearing practices in Chinese families in Beijing and Hong Kong. The sample consisted of 89 mothers in Beijing and 45 mothers in Hong Kong. The mothers were instructed to respond to the Child‐rearing Practice Report (CRPR) in Q‐sort format. Some of the item clusters were combined to produce the authoritarian and authoritative disciplinary styles. The results indicated that mothers in Hong Kong were more likely to adopt an authoritarian child‐rearing pattern than mothers in Beijing; however, the two groups did not differ in authoritative child‐rearing style. The results also showed that mothers in Hong Kong controlled their children more than their counterparts in Beijing, and they were less inclined to show affection towards their children; mothers in Beijing emphasized their children's achievement much more than their Hong Kong counterparts. The findings suggest that Chinese parental disciplinary styles may be quite different in various regions of Chinese societies. Such variance across different geopolitical locations within the same cultural background has been ignored in past cross‐cultural research.     

The Tractarian Operation N and Expressive Completeness

The purpose of this paper is threefold. First, I visit the Fogelin–Geach-dispute, criticizeMiller's interpretation of the Geachian notationN(x:N(fx)) and conclude that Fogelin's argumentagainst the expressive completeness of the Tractariansystem of logic is unacceptable and that the adoptionof the Geachian notation N(x:fx) would not violate TLP5.32. Second, I prove that a system of quantificationtheory with finite domains and with N as the solefundamental operation is expressively complete. Lastly, I argue that the Tractarian system is apredicate-eliminated many-sorted theory (withoutidentity) with finite domains and with N as the solefundamental operation, and thus is expressivelycomplete.     

When Vague Sentences Inform: A Model Of Assertability

A speaker often decides whether or not to saysomething based on his assessment of the impact itwould have on his hearer's beliefs. If he thinks itwould bring them more in line with the truth, he saysit; otherwise he does not. In this paper, I developa model of these judgments, focusing specifically onthose of vague sentences. Under the simplifyingassumption that an utterance only conveys a speaker'sapplicability judgments, I present a Bayesian model ofan utterance's impact on a hearer's beliefs. Fromthis model I derive a model of a speaker's judgment ofwhether or not an utterance would be informative. Iillustrate it with several examples of judgments ofvague and non-vague sentences. For instance, I showthat it models the common judgment that assertingeither ``George is tall' or ``George is not tall' wouldbe misleading if George were borderline tall, butasserting ``George is tall and he isn't tall' would notbe.     

Laws, Regularities and Exceptions

Sentences of the form ' F s are G s' can express laws of nature, weaker Special Science laws, and also regularities which are not a part of any explicit science. These so-called generic sentences express nomic relationships which may have exceptions. I discuss the kinds of regularities expressed by generic sentences and argue that since they play a similar role in determining our ability to categorise and reason about the world, we should look for a unified treatment of them.
