Bilingual and monolingual infants differ in how they process linguistic aspects of the speech signal. But do they also differ in how they process non-linguistic aspects of speech, such as who is talking? Here, we addressed this question by testing Canadian monolingual and bilingual 9-month-olds on their ability to learn to identify native…

The relation between mental imagery and visual perception is a long debated topic in experimental psychology. In a recent study, Wantz, Borst, Mast, and Lobmaier (2015) demonstrated that color imagery could benefit color perception in a task that involved generating imagery in response to a cue prior to a forced-choice color discrimination task.…

The benefit of permanent prompts depends on the extent to which their use is generalized. Previous research has demonstrated both control by and efficacy of pictorial prompts (e.g., Phillips & Vollmer, 2012). The present studies similarly evaluated stimulus control by textual prompts. Six school aged children with intellectual disabilities…

Children learn about the world through others' testimony, and much of this knowledge likely comes from parents. Furthermore, parents may sometimes want children to share their beliefs about topics on which there is no universal consensus. In discussing such topics, parents may use explicit belief statements (e.g., "Evolution is real") or…

Guessing translations of foreign words ("hodei?"), before viewing corrective feedback ("hodei-cloud"), leads to better subsequent memory for correct translations than studying intact pairs ("hodei-cloud"), even when guesses are always incorrect (Potts & Shanks, 2014), but the mechanism underlying this effect is…

Distributional models of semantics learn word meanings from contextual co-occurrence patterns across a large sample of natural language. Early models, such as LSA and HAL (Landauer & Dumais, 1997; Lund & Burgess, 1996), counted co-occurrence events; later models, such as BEAGLE (Jones & Mewhort, 2007), replaced counting co-occurrences…

Curriculum guidelines and professional organizations' recommendations lack details about how often and how much students should write in mathematics and what characteristics should define their writing. This study presents an analytic framework that addresses how often students are prompted in student mathematics books to write, how much they may…

Netrin-1 was initially characterized as an axon guidance molecule that is essential for normal embryonic neural development; however, many types of neurons continue to express netrin-1 in the postnatal and adult mammalian brain. Netrin-1 and the netrin receptor DCC are both enriched at synapses. In the adult hippocampus, activity-dependent…

Trait anxiety is considered to be a risk factor for anxiety disorders. The aim of the present study was to investigate how trait anxiety affects associative learning during and after an aversive event in laboratory rats. For this, rats were first submitted to a light-dark box test, followed by relief, safety, and fear learning. Our data…

The main question that this thesis addresses is: in what way does structural information enter into the processing of long-distance dependencies? Does it constrain the computations, and if so, to what degree? Available experimental evidence suggests that sometimes structurally illicit but otherwise suitable constituents are accessed during…

Purpose: The goal of this study was to assess the listening behavior and social engagement of cochlear implant (CI) users and normal-hearing (NH) adults in daily life and relate these actions to objective hearing outcomes. Method: Ecological momentary assessments (EMAs) collected using a smartphone app were used to probe patterns of listening…

Purpose: Children with hearing loss (HL), including those with hearing aids (HAs) and cochlear implants (CIs), often have difficulties contrasting words like "beach" versus "peach" and "dog" versus "dock" due to challenges producing systematic voicing contrasts. Even when acoustic contrasts are present,…

The temporal contiguity effect (TCE) is the tendency for the recall of one event to cue recall of other events originally experienced nearby in time. Retrieved context theory proposes that the TCE results from fundamental properties of episodic memory: binding of events to a drifting context representation during encoding and the reinstatement of…

We investigate effects of prosodic cues on interpretation of ambiguous sentences containing relative clauses (RCs) in English by Spanish-speaking learners. English and Spanish differ in default preference for RC attachment: English has a weak low attachment (LA) preference (RC modifies NP2); Spanish has a stronger high attachment (HA) preference…

Cultural experiences can influence how people attend to different emotional cues. Whereas semantic content explicitly describes feelings, vocal tone conveys implicit information regarding emotions. This cross-cultural study examined children's attention to emotional cues in spoken words. The sample consisted of 121 European American (EA) and 120…
