A fundamental aspect of decision making is the speed-accuracy tradeoff (SAT): slower decisions tend to be more accurate, but because time is a scarce resource people prefer to conclude decisions more quickly. The current research adds to the SAT literature by documenting two previously unrecognized influences on the SAT: perception shifts and goal…

There has been considerable interest in what components of decision-making change when speed or accuracy is stressed. In many early studies, quite strict assumptions were made about parameter invariance across experimental conditions (sometimes called selective influence). Here we fit the standard diffusion model to the data from four large…

Many previous studies observed that higher retrospective confidence ratings about memory performance were associated with shorter response times in memory test. Researchers often interpret response time as a measure of retrieval fluency which is an important cue utilized in confidence formation process. However, the drift diffusion model (DDM)…

Children tend to make more last-minute locomotor adjustments than adults when avoiding stationary obstacles. The purpose of this study was to compare avoidance behaviors of middle-aged children (10-12 years old) with young adults during a head-on collision course with an approaching virtual pedestrian. Participants were immersed in a virtual…

It has widely been accepted that aggregating group-level decisions is superior to individual decisions. As compared to individuals, groups tend to show a decision advantage in their response accuracy. However, there has been a lack of research exploring whether group decisions are more efficient than individual decisions with a faster…

Previous research has investigated the Spatial Numerical Associations of Response Codes (SNARC) effect as a measure of spatial number coding in relation to mathematics (Cipora et al., 2020, https://doi.org/10.1111/nyas.14355). An issue that arises if one wants to correlate mathematical performance with the SNARC effect, is how individual…

Purpose: Adults recognize words that are acquired during childhood more quickly than words acquired during adulthood. This is known as the Age of Acquisition (AoA) effect. The AoA effect, according to the integrated account, manifests in tasks necessitating greater semantic processing and in tasks with arbitrary input-output mapping. Compound…

The role of morphology in learning to read can vary widely across languages and is related to the extent to which the morphological system is a dominant feature of the specific language. The present study focuses on Arabic, a Semitic language written in an "abjad" (consonantal writing system) and characterized by rich morphological…

Two experiments are presented that use tasks common in research in numerical cognition with young adults and older adults as subjects. In these tasks, one or two arrays of dots are displayed, and subjects decide whether there are more or fewer dots of one kind than another. Results show that older adults, relative to young adults, tend to rely…

Purpose: We investigated developmental differences in a dual task involving rhyming and tone judgment/decisions and the effects of varying cognitive demands on task performance. Method: Participants were 7- to 11-year-olds, 12- to 15-year-olds, and adults between 18 and 40 years (n = 19 per group). The rhyming task consisted of three stimuli…

Research on first language (L1) attrition typically focuses on immigrant populations in their second language (L2) environment, yet we know comparably little about L1 attrition in the L1 setting. This study used two lexical tasks to test L1 attrition, a time-sensitive word decision task and a video retelling. Chinese teachers of English vs.…

In the traditional conception of working memory for word lists, phonological codes are used primarily, and semantic codes are often discarded or ignored. Yet, other evidence indicates an important role for semantic codes. We carried out a preplanned set of four experiments to determine whether phonological and semantic codes are used similarly or…

The development of emergent literacy, a precursor to formal reading, has been linked to subsequent conventional literacy skills in Chinese children. The factors important for acquiring Chinese reading skills, such as phonological and morphological awareness, have primarily been studied in primary school children rather than preschoolers. The…

Background: Evidence indicates that fluent readers automatically decompose morphologically complex words. However, few studies have directly compared processing of stimuli comprising different types of morphemes, particularly bound and free morphemes. Methods: Eighty fluently reading young adults participated in a lexical decision task with word…

The same-different task is a classic paradigm that requires participants to judge whether two successively presented stimuli are the same or different. While this task is simple, with results that have been replicated many times, response times (RTs) and accuracy for both same and different decisions remain difficult to model. The biggest obstacle…
