In this study, we evaluated the effect of individualized, embedded choice opportunities in daily routines on the task initiations and protests by one man with severe disabilities. An initial functional analysis conducted during Phase 1 revealed that low rates of participation and high rates of protests in household activities were related to prompts that offered no control. Subsequently in Phase 2, we modified prompts within three different routines to provide greater control through choice. Within the context of an A-B-A-B design, the effects of a “traditional” no-choice versus choice task analysis were evaluated in each routine across three staff. The results demonstrated that when routines included opportunities for choice, task initiations were high, whereas protests, including severe aggression, were virtually eliminated. These results are discussed in relation to their implications for participant control, individualizing choice opportunities, embedding choice in daily routines, and the prevention of problem behaviors.

This paper investigates the effects of two display characteristics on decisions in a preferential choice task under conditions of strict uncertainty. Participants receiving information in tabular format (n = 83) made fewer compensatory choices, more maximin choices, and selected dominated alternatives more often when outcome distributions were described in terms of a midpoint and variability rather than minimum and maximum values. In contrast, participants given data in a graphical format (n = 80) made more compensatory choices with midpoint-variability than with min-max graphs. Participants given information in graphical format selected fewer dominated alternatives than did participants who received the same information in tabular format. These findings have important policy implications. While it may be desirable to use display characteristics to influence employees to make decisions consistent with organizational policies, the desirability of providing such “persuasive” decision guidance is problematic in settings where the information provider and the decision maker are independent parties to an economic exchange.

Purpose Previous studies showed early production precedes late perception in Cantonese tone acquisition, contrary to the general principle that perception precedes production in child language. How tone production and perception are linked in 1st language acquisition remains largely unknown. Our study revisited the acquisition of tone in Cantonese-speaking children, exploring the possible link between production and perception in 1st language acquisition. Method One hundred eleven Cantonese-speaking children aged between 2;0 and 6;0 (years;months) and 10 adolescent reference speakers participated in tone production and perception experiments. Production materials with 30 monosyllabic words were transcribed in filtered and unfiltered conditions by 2 native judges. Perception accuracy was based on a 2-alternative forced-choice task with pictures covering all possible tone pair contrasts. Results Children's accuracy of production and perception of all the 6 Cantonese tones was still not adultlike by age 6;0. Both production and perception accuracies matured with age. A weak positive link was found between the 2 accuracies. Mother's native language contributed to children's production accuracy. Conclusions Our findings show that production and perception abilities are associated in tone acquisition. Further study is needed to explore factors affecting production accuracy in children.

Summary: We review the rationale for behavioral clinical case formulations and emphasize the role of the functional analysis in the design of individualized treatments. Standardized treatments may not be optimally effective for clients who have multiple behavior problems. These problems can affect each other in complex ways and each behavior problem can be influenced by multiple, interacting causal variables. The mechanisms of action of standardized treatments may not always address the most important causal variables for a client's behavior problems. The functional analysis integrates judgments about the client's behavior problems, important causal variables, and functional relations among variables. The functional analysis aids treatment decisions by helping the clinician estimate the relative magnitude of effect of each causal variable on the client's behavior problems, so that the most effective treatments can be selected. The parameters of, and issues associated with, a functional analysis and Functional Analytic Clinical Case Models (FACCM) are illustrated with a clinical case. The task of selecting the best treatment for a client is complicated because treatments differ in their level of specificity and have unequally weighted mechanisms of action. Further, a treatment's mechanism of action is often unknown.
