The present study investigated the effects of positive and negative GABA[subscript A] modulators under three different baselines of repeated acquisition in squirrel monkeys in which the monkeys acquired a three-response sequence on three keys under a second-order fixed-ratio (FR) schedule of food reinforcement. In two of these baselines, the…

Quantitative analyses of stimulus control and reinforcer control in conditional discriminations and delayed matching-to-sample procedures often encounter a problem; it is not clear how to analyze data when subjects have not made errors. The present article examines two common methods for overcoming this problem. Monte Carlo simulations of…

In Phase 1, 4 pigeons were trained on a three-component multiple concurrent-chains procedure in which components differed only in terms of relative terminal-link entry rate. The terminal links were variable-interval schedules and were varied across four conditions to produce immediacy ratios of 4:1, 1:4, 2:1, and 1:2. Relative terminal-link entry…

If manufacturing a safer cigarette is technically possible--an open question--then mandating that tobacco manufacturers improve the safety of cigarettes would likely have both positive and negative implications for the nation's health. On the one hand, removing toxins may reduce the incidence of smoking-related diseases and premature mortality in…

This qualitative study explores how male students from different racial backgrounds experience racial diversity within racially diverse or homogeneous friendship groups. Based on an inductive analysis of purposive interviews, the author found that diverse friendships among men may result from both an attitude of intentionality with regard to…

The past decade has seen a tremendous growth in the use of structural equation modeling (SEM) to address research questions in 2 subfields of behavioral science: cancer prevention and control (e.g., determinants of cancer screening adherence) and behavioral oncology (e.g., determinants of psychosocial adjustment among cancer patients or…

This article looks at how behavioral research can be an effective tool to use during the redesign process of university plazas. It also summarizes the research that was conducted at University Union Plaza at California Polytechnic State University (Cal Poly), a 30-year-old plaza that is scheduled to be redesigned. Through the use of behavioral…

"The Alex Studies: Cognitive and Communicative Abilities of Grey Parrots" by Irene Pepperberg is reviewed from a behavior analytic orientation. The results of the majority of her experiments are discussed in terms drawn from the general literature of behavior analysis and Skinner's analysis of verbal behavior. We conclude that she has provided…

Can one be open-minded about a strongly held belief? I defend a reconciliation of the suggested conflict that turns on open-mindedness as an educational aim subordinate to the aim of knowledge, and as an attitude about one's beliefs (a second-order or meta-belief), not a weakened attitude toward a proposition believed. The reconciliation is…

TgCRND8 mice represent a transgenic mouse model of Alzheimer's disease, with onset of cognitive impairment and increasing amyloid-[beta] plaques in their brains at 12 weeks of age. In this study, the spatial memory in 25- to 30-week-old TgCRND8 mice was analyzed in two reference and one working memory Morris water maze (MWM) tests. In reference…

The impact of a previously successful or unsuccessful experience on the subsequent acquisition of a related task is not well understood. The nature of past experience may have even greater impact in individuals with learning deficits, as their cognitive processes can be easily disrupted. Mice with a targeted disruption of the [alpha] and [delta]…

Men largely are neglected in research on eating disturbances, including research on the eating disorder continuum. This research explored whether the eating disorder continuum provides an accurate representation for men of characteristics related to disturbed eating in women. Results for a sample of 166 men were mixed, offering limited support for…

Researchers are analyzing the root causes for the universal problem of chronic academic procrastination, which is believed to raise student's anxiety and sinks their self-esteem. Colleges of Belgium, Canada, and Netherlands have begun to develop counseling programs that draw on cognitive and behavioral research to help students lessen…

Undergraduate students routinely rated science-related courses such as biopsychology as intimidating and very difficult. Identification of factors that may contribute to success in these types of courses is important in order to help increase performance and interest in these topics. To examine what variables are related to performance, we studied…

Following the behavior-analytic tradition of analyzing individual behavior, the present research investigated demand elasticity of individual consumers purchasing supermarket products, and compared individual and group analyses of elasticity. Panel data from 80 UK consumers purchasing 9 product categories (i.e., baked beans, biscuits, breakfast…
