Citizen science has gained importance in recent years and revealed great potential, especially regarding science learning and environmental education. However, little is known about ways of supporting individual learning processes within citizen science. With this in mind, a home experiment set, the Nitrogen Box, was developed within a chemistry…

This study examines the science learning experiences across the lifespan of two groups of college students: adults with intellectual and/or developmental disabilities in a post-secondary inclusive program, and adults in a preservice secondary education teacher candidate program. Data, in the form of personal narrative science stories were…

Phonotactics--constraints on the position and combination of speech sounds within syllables--are subject to statistical differences that gradiently affect speaker and listener behavior (e.g., Vitevitch & Luce, 1999). What statistical properties drive the acquisition of such constraints? Because they are naturally highly correlated, previous…

Aim: We aimed to explore the organization of the calendar knowledge base underlying date calculation by assessing the ability of savant calendar calculators to free recall a series of date lists. Method: Four experiments are reported that assessed recall of structural and non-structural features of the calendar in eight savant calendar calculators…

The mainstream agricultural literacy movement has been mostly focused on school-based learning through formal curricula and standardized non-formal models (e.g., FFA, 4-H). The purpose of the current study is to qualitatively explore through a grounded theory approach, the development, sharing, and translation of diverse forms of agricultural…

In this article we report on listener categorization of meaningful environmental sounds. A starting point for this study was the phenomenological taxonomy proposed by Gaver (1993b). In the first experimental study, 15 participants classified 60 environmental sounds and indicated the properties shared by the sounds in each class. In a second…

The uncanny valley--the unnerving nature of humanlike robots--is an intriguing idea, but both its existence and its underlying cause are debated. We propose that humanlike robots are not only unnerving, but are so because their appearance prompts attributions of mind. In particular, we suggest that machines become unnerving when people ascribe to…

Adults can incrementally combine information from speech with astonishing speed to anticipate future words. Concurrently, a growing body of work suggests that vocabulary ability is crucially related to lexical processing skills in children. However, little is known about this relationship with predictive sentence processing in children or adults.…

In the present paper, we (1) study whether people differ in the equity models they use, and (2) test whether individual differences in equity models relate to individual differences in equity sensitivity. To achieve this goal, an Information Integration experiment was performed in which participants were given information on the performance of two…

Sidman (1994) noted that the existence of a member that is common to more than one class may produce either class merger (union) or class intersection. A multiple-selection, matching-to-sample test was developed to examine the conditions under which these outcomes occur. Test trials each required three conditional discriminations involving…

Where are we? In three experiments, we explore preschoolers' and adults' intuitions about the location of the self using a novel method that asks when an object is closet to a person. Children and adults judge objects near a person's eyes to be closer to her than objects near other parts of her body. This holds even when considering an alien…

In order to be adaptive, cognition requires knowledge about the statistical structure of the environment. We show that decision performance and the selection between cue-based and exemplar-based inference mechanisms can depend critically on how this knowledge is acquired. Two types of learning tasks are distinguished: "learning by comparison", by…

The exhibition of actions that are causally unnecessary to the outcomes with which they are associated is a core feature of human cultural behavior. To enter into the world(s) of their cultural in-group, children must learn to assimilate such unnecessary actions into their own behavioral repertoire. Past research has established the habitual…

This study tests whether the detrimental effects of strong diversity faultlines on team performance can be counteracted by combining 2 managerial strategies: task role crosscutting and superordinate goals. We conducted a 2 (crosscut vs. aligned roles) x 2 (superordinate vs. subgroup goals) experimental study. Seventy-two 4-person teams with…

Three experiments examine whether a naturalistic reading task can induce long-lasting changes of syntactic patterns in memory. Judgment of grammatical acceptability is used as an indirect test of memory for sentences that are identical or only syntactically similar to those read earlier. In previous research (Luka & Barsalou, 2005) both sorts of…
