Representations of the fingers are embodied in our cognition and influence performance in enumeration tasks. Among deaf signers, the fingers also serve as a tool for communication in sign language. Previous studies in normal hearing (NH) participants showed effects of embodiment (i.e., embodied numerosity) on tactile enumeration using the fingers…

There is a long-standing debate over whether the passage of time causes forgetting from working memory, a process called trace decay. Researchers providing evidence against the existence of trace decay generally study memory by presenting familiar verbal memory items for 1 s or more per memory item, during the study period. In contrast,…

Research demonstrating that infants discriminate between small (e.g., 1 vs. 3 dots) and large numerosities (e.g., 8 vs. 16 dots) is central to theories concerning the origins of human numerical abilities. To date, there has been no quantitative meta-analysis of the infant numerical competency data. Here, we quantitatively synthesize the evidential…

Purpose: The purpose was (1) to test a new version of a mental rotation task (MRT), which assesses mental rotation abilities of men and women for sport-specific items, and (2) to investigate potential differences in MRT performance, which are based on athletic expertise. Methods: Eighty-eight basketball experts (42 females) and 123 novices (64…

Contextual cueing refers to the guidance of search by associative learning of the location of task-relevant target items in relation to the consistent arrangement of distractor ("context") items in the search display. The present study investigated whether such target-distractor associations could also be formed in a cross-modal search…

Infant research is providing accumulating evidence that number-space mappings appear early in development. Here, a Posner cueing paradigm was used to investigate the neural mechanisms underpinning the attentional bias induced by nonsymbolic numerical cues in 9-month-old infants (N = 32). Event-related potentials and saccadic reaction time were…

Participants with autism spectrum disorder (ASD) (n = 121, mean [SD] age: 14.6 [8.0] years) and typically developing (TD) controls (n = 40, 16.4 [13.3] years) were presented with a series of videos representing biological motion on one side of a computer monitor screen and non-biological motion on the other, while their eye movements were…

Speech in everyday conversations is riddled with discourse markers (DMs), such as "well," "you know," and "like." However, in many lab-based studies of speech comprehension, such DMs are typically absent from the carefully articulated and highly controlled speech stimuli. As such, little is known about how these DMs…

Our visual system samples external information, adjusts its sensitivity and constructs a stable representation of the world that allows us to perceive and interact with objects in our environments. Visual information with different levels of complexity is processed through the hierarchically organized visual cortical areas. This dissertation…

This study examined behavioral, heart rate (HR), and event-related potential (ERP) correlates of attention and recognition memory for 4.5-, 6-, and 7.5-month-old infants (N = 45) during stimulus encoding. Attention was utilized as an independent variable using HR measures. The Nc ERP component associated with attention and the late slow wave (LSW)…

In the present study, we investigated the accuracy of eyewitness accounts over time from a metacognitive perspective, in which post-retrieval monitoring and control processes play a crucial role in mediating between memory retrieval and ultimate memory performance. In two experiments, participants viewed a narrated slide show depicting ordinary…

This dissertation investigates the impact of cross-modal binding on word reading skills among English Language Learners (ELLs). Using Baddeley's updated working memory model, which includes the Episodic Buffer, this study examines how the ability to bind visual and phonological information in memory influences the reading development of ELL…

Children's ability to discriminate nonsymbolic number (e.g., the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest that it may be due to a sharpening numerical representation or an improved…

Eye tracking is becoming increasingly popular in physics education research (PER). As technology has advanced considerably in recent years and has become more user friendly, it is anticipated that eye tracking will play an increasingly significant role in assessing student learning at the process level in future studies. The main objective of this…

Emotion can influence various cognitive processes. Communication with children often involves exaggerated emotional expressions and emotive language. Children with autism spectrum disorder often show a reduced tendency to attend to emotional information. Typically developing children aged 7 to 9 years who varied in their level of autism-like…
