Latency‐based functional analysis in schools: Correspondence and differences across environments

Functional analyses were conducted for problem behavior of three girls with intellectual and developmental disabilities. Analyses conducted under analog conditions measured rate and latency. Latency‐based functional analyses were conducted in a classroom setting in multielement and reversal designs. Correspondence was identified between the standard functional analysis and the two latency analyses for one participant. Partial correspondence was found with the other two participants. These results are discussed in light of research on adaptions for functional analysis in classroom settings.     

Practice does not facilitate acquisition of McCollough effects: Evidence against a learning model

Previous investigators (Schmidt, Pinetts, & Finke, 1978) have asserted that McCollough effects (MEs) are acquired more readily by experienced than by inexperienced subjects. The present experiments examine this claim in a paradigm that utilizes quantitative measurements of MEs to evaluate possible changes in subjects’ susceptibility to them. MEs were induced every few days for approximately 2 months; results revealed no progressive increments in either strength or acquisition rats. The lack of facilitation due to practice is inconsistent with learning models proposed to account for MEs.     

Citizen participation and emprowerment: The case of local environmental hazards

Local environmental hazards place millions of citizens at risk of physical, emotional, and financial harm. While the discovery of such hazards can be fundamentally disempowering for individuals and communities, few scholars have examined the dynamics of empowerment in this context. We explore the relationships among forms of empowerment, citizen participation, and local environmental hazards, and offer a model of the processes of empowerment and disempowerment appropriate to a broad range of citizen issues. On the basis of this analysis we recommend a partnership approach to community decision making that is designed both to reduce the likelihood that local environmental hazards will develop and to minimize the disempowering impact of any threats that do occur.     

Age effects shrink when motor learning is predominantly supported by nondeclarative, automatic memory processes: evidence from golf putting

Can motor learning be equivalent in younger and older adults? To address this question, 48 younger (M = 23.5 years) and 48 older (M = 65.0 years) participants learned to perform a golf-putting task in two different motor learning situations: one that resulted in infrequent errors or one that resulted in frequent errors. The results demonstrated that infrequent-error learning predominantly relied on nondeclarative, automatic memory processes whereas frequent-error learning predominantly relied on declarative, effortful memory processes: After learning, infrequent-error learners verbalized fewer strategies than frequent-error learners; at transfer, a concurrent, attention-demanding secondary task (tone counting) left motor performance of infrequent-error learners unaffected but impaired that of frequent-error learners. The results showed age-equivalent motor performance in infrequent-error learning but age deficits in frequent-error learning. Motor performance of frequent-error learners required more attention with age, as evidenced by an age deficit on the attention-demanding secondary task. The disappearance of age effects when nondeclarative, automatic memory processes predominated suggests that these processes are preserved with age and are available even early in motor learning.     

Musicians experience less age-related decline in central auditory processing

Age-related decline in auditory perception reflects changes in the peripheral and central auditory systems. These age-related changes include a reduced ability to detect minute spectral and temporal details in an auditory signal, which contributes to a decreased ability to understand speech in noisy environments. Given that musical training in young adults has been shown to improve these auditory abilities, we investigated the possibility that musicians experience less age-related decline in auditory perception. To test this hypothesis we measured auditory processing abilities in lifelong musicians (N = 74) and nonmusicians (N = 89), aged between 18 and 91. Musicians demonstrated less age-related decline in some auditory tasks (i.e., gap detection and speech in noise), and had a lifelong advantage in others (i.e., mistuned harmonic detection). Importantly, the rate of age-related decline in hearing sensitivity, as measured by pure-tone thresholds, was similar between both groups, demonstrating that musicians experience less age-related decline in central auditory processing.     

Distinct task-independent visual thresholds for egocentric and allocentric information pick up

The dominant view of the ventral and dorsal visual systems is that they subserve perception and action. De Wit, Van der Kamp, and Masters (2011) suggested that a more fundamental distinction might exist between the nature of information exploited by the systems. The present study distinguished between these accounts by asking participants to perform delayed matching (perception), pointing (action) and perceptual judgment responses to masked Müller-Lyer stimuli of varying length. Matching and pointing responses of participants who could not perceptually judge stimulus length at brief durations remained sensitive to veridical stimulus length (egocentric information), but not the illusion (allocentric, context-dependent information), which was effective at long durations. Distinct thresholds for egocentric and allocentric information pick up were thus evident irrespective of whether perception (matching) or action (pointing) responses were required. It was concluded that the dorsal and ventral systems may be delineated fundamentally by fast egocentric- and slower allocentric information pick up, respectively.

Assessing the Development of the Sales Profession

As we celebrate the silver anniversary of this journal, it is time to assess the development of sales as a profession. This paper uses the sociology of work literature to develop six criteria society uses in making the attribution of a work group as a profession. Sales is then examined on each of those six dimensions. It is concluded that our discipline meets or exceeds four of the requirements, has mixed results on one construct, and falls short on another criterion. Progress will require the development and enforcement of an ethical code. A strong professional association for all salespeople across all industries could also be very useful in this regard. Future use of technology by salespeople will also impact client views of sales as a profession.
