The role of brothers and sisters in the gender development of preschool children

The study examined whether the sex of older siblings influences the gender role development of younger brothers and sisters of age 3 years. Data on the Pre-School Activities Inventory, a measure of gender role behavior that discriminates within as well as between the sexes, were obtained in a general population study for 527 girls and 582 boys with an older sister, 500 girls and 561 boys with an older brother, and 1665 singleton girls and 1707 singleton boys. It was found that boys with older brothers and girls with older sisters were more sex-typed than same-sex singletons who, in turn, were more sex-typed than children with other-sex siblings. Having an older brother was associated with more masculine and less feminine behavior in both boys and girls, whereas boys with older sisters were more feminine but not less masculine and girls with older sisters were less masculine but not more feminine.     

Behavior analysis and the R&D paradigm

This paper considers research and development (R&D) as a style of investigation that holds promise for the field of behavior analysis. Contrasted with academic-style research, R&D tends to be highly targeted toward achievement of specific outcomes, which are determined by a user community. R&D is typically multidisciplinary in character and is coordinated by a funding source. R&D usually includes extensive field testing and systematically addresses technology transfer. A program of R&D focused on detector dogs serves as an exemplar of this approach for behavior analysis.     

To Be or Not to Be: Exploring the Nature of Positively and Negatively Keyed Personality Items in High-Stakes Testing

Including equal numbers of positively and negatively keyed items is common in Five-Factor Model (FFM) personality measures. Much literature has demonstrated the presence of positive and negative keying factors in low-stakes testing situations, but there is a dearth of research investigating these factors in high-stakes testing. To address this gap, we investigated whether an FFM measure used in high-stakes testing was influenced by positive and negative keying factors. We also examined the overlap of the positive and negative keying factors with social desirability, rule-consciousness, acquiescence, and cognitive ability. Confirmatory factor analysis supported the inclusion of distinct factors associated with positively and negatively keyed items and suggested that the keying factors accounted for a substantial portion of variation in responses to FFM items. Social desirability and rule-consciousness were found to have significant relations with both keying factors, whereas acquiescence was only related to the negative keying factor. Implications for the construct validity of FFM measures used in high-stakes testing and directions for future research are discussed.     

Psychometric properties of the mini-social phobia inventory (Mini-SPIN) in a large online treatment-seeking sample

The Mini-Social Phobia Inventory (Mini-SPIN) is a brief, three-item measure designed as a screening tool for social anxiety disorder (SAD). This study investigated the Mini-SPIN’s psychometric properties in a series of trials of Internet-delivered treatment. Participants were 993 people seeking Internet-delivered cognitive behavioural therapy for a range of anxiety and mood disorders. Participants completed the Mini-SPIN, and were diagnosed using the Mini International Neuropsychiatric Interview Version 5.0.0 (MINI). They also completed measures of depression, general anxiety, panic, neuroticism and general impairment. The Mini-SPIN’s ability to discriminate between people with and without SAD, within a large sample of people seeking treatment for a range of psychological disorders, was assessed at initial assessment and three-month follow-up. The Mini-SPIN’s criterion group validity, internal consistency, test–retest reliability, construct validity and responsiveness to treatment were also examined. Results demonstrated that the Mini-SPIN has an excellent ability to discriminate between those with and without SAD in a highly comorbid clinical sample, and also has good criterion group validity. The Mini-SPIN also exhibited excellent internal consistency, good test–retest reliability, and was responsive to treatment. These results highlight the Mini-SPIN’s potential as an efficient and reliable measure of SAD in heterogenous populations.     

Screening Job Applicants: The Impact of Physical Attractiveness and Application Quality

The present study investigated the impact of physical attractiveness and résuméquality on the evaluation of job applicants in the screening phase of the selection process. One hundred and eighty participants were asked to imagine they were a recruiting officer and to screen an application for the position of graduate trainee manager. Participants read a job advertisement and one of two versions of a curriculum vitae, which differed in quality. Attached to the front page of each curriculum vitae was a passport-sized head-and-shoulders photograph of either an average or an attractive female. A control condition with no attached photograph was also included. Participants judged the likelihood with which they would offer an interview to the applicant, the quality of the application, and the likely starting salary they would offer the applicant. Results indicated that attractiveness had no impact when the quality of the application was high but that attractiveness was an advantage when the application was mediocre. When the résumé quality was average the attractive applicant was evaluated more positively than the control, no photograph, applicant; an attractive photograph boosted the evaluation of a mediocre application. Results are discussed in terms of discrimination and implications for the field of human resource management.     

Resampling programs for multiway contingency tables with fixed marginal frequency totals

A resampling algorithm is presented for analyzing multiway contingency tables with fixed marginal frequency totals. Applications are illustrated with extensions of Fisher's exact, Pearson's chi-squared, and likelihood-ratio tests to three-way contingency tables.     

An experimental comparison between rival theories of rapid automatized naming performance and its relationship to reading

Two studies investigated the degree to which the relationship between rapid automatized naming (RAN) performance and reading development is driven by shared phonological processes. Study 1 assessed RAN, phonological awareness, and reading performance in 1010 7- to 10-year-olds. Results showed that RAN deficits occurred in the absence of phonological awareness deficits. These were accompanied by modest reading delays. In structural equation modeling, solutions where RAN was subsumed within a phonological processing factor did not provide a good fit to the data, suggesting that processes outside phonology may drive RAN performance and its association with reading. Study 2 investigated Kail's proposal that speed of processing underlies this relationship. Children with single RAN deficits showed slower speed of processing than did closely matched controls performing normally on RAN. However, regression analysis revealed that RAN made a unique contribution to reading even after accounting for processing speed. Theoretical implications are discussed.     

The varying effects of age of acquisition

There are a number of theories that suggest that age of acquisition (AoA) effects are not uniform across different tasks. Catling and Johnston (2006a) found greater AoA effects within an object-naming task than in a semantic classification task. They explained these findings by suggesting that AoA effects might accumulate according to how many levels of representation a task necessitates access to. Brysbaert and Ghyselinck (2006) explain the difference in AoA effects by proposing two distinct types of AoA (frequency dependent and frequency independent), the first accounted for by a connectionist-type mechanism and the latter situated at the interface between semantics and word production. Moreover, Moore, Smith-Spark, and Valentine (2004) and Holmes and Ellis (2006) have suggested that there are two loci of AoA effects: at the phonological level and somewhere within the perceptual level of representation. Again, this could account for the varying degrees of AoA effects. This study sets about testing these ideas by assessing the effect size of AoA across a series of different tasks that necessitate access to various levels of representation. Experiments 1-4 demonstrate significant effects of AoA in a novel picture-picture verification task, an object classification task, a picture verification task, and an object-naming task. Experiment 5 showed no effects of initial phoneme on the naming of the critical objects used within Experiments 1-4. The implication of the varying AoA effect sizes found within Experiments 1-4 in relation to explanations of AoA are discussed.     

Promising New Developments in the Therapist–Client Relationship: A Philosophy of Science Review and Preview

Two questions were central: What are the current and what were the past new developments in the therapist–client relationship? By means of a “philosophy of science analysis,” what principles may be taken as helping to account for these new developments? Nine principles were identified in a review, including the articles in the present theme issue of the journal. The proposal and invitation are to use these nine principles to generate further, future, promising new developments in the therapist–client relationship.
