An exploratory investigation of coffee and lemon scents and odor identification

Fragrance sellers often provide coffee beans to their customers as a "nasal palate cleanser," to reduce the effects of olfactory adaptation and habituation. To test this idea, college students smelled three fragrances multiple times, rating odors each time. After completing nine trials, participants sniffed coffee beans, lemon slices, or plain air. Participants then indicated which of four presented fragrances had not been previously smelled; Coffee beans did not yield better performance than lemon slices or air.     

BRIEF REPORT: LATENCY FUNCTIONAL ANALYSIS OF ELOPEMENT

Elopement is a potentially dangerous problem behavior prevalent among individuals with developmental disabilities. However, functional analysis of elopement presents unique challenges including potential confounds because of the need for participant retrieval during functional analysis sessions. In the current study, we implemented a latency functional analysis with an eight‐year‐old child with an intellectual disability, in which the dependent measure was latency to elopement. Following the latency functional analysis, a functional communication intervention was developed and its effectiveness in decreasing elopement was evaluated using an ABAB design. Findings suggest that a functional analysis of latency may be a suitable methodology to identify the operant function of elopement. Copyright © 2013 John Wiley & Sons, Ltd.
