The Spacing Effect In Remote Information-Integration Category Learning, Anthony Cruz
The Spacing Effect In Remote Information-Integration Category Learning, Anthony Cruz
Electronic Thesis and Dissertation Repository
The present study examined whether the temporal distribution of procedural category learning experiences would impact learning outcomes. Participants completed the remote category learning study on a smartphone in one of two learning conditions: Massed (control) or distributed. Consistent with expectations, distributed learners reached higher accuracy levels. This effect disappeared after accounting for reaction time differences, suggesting that it was driven by attentional mechanisms. Distribution may have made participants more likely discover the optimal categorization strategy and more robust to sensory habituation. Counter to previous findings, participants favored distributed learning. These results suggest that adult category learning is facilitated by temporal …
Temperament And Individual Differences In Category Learning, Tianshu Zhu
Temperament And Individual Differences In Category Learning, Tianshu Zhu
Electronic Thesis and Dissertation Repository
Objectives. Individuals can differ in their strategic approach in learning the same categorization task, researchers have sought to study what specific stable individual differences traits can help explain these differences. This dissertation first surveyed extant literature on the impact of trait differences on category learning then examined the effect of temperament traits on these dependent variables. Chapter 2 (scoping review): This scoping review synthesized the past literature that examined the relationship between sources of stable individual differences and category learning performance and strategy use outcomes. Five database platforms were searched to identify relevant articles, cross-referencing was also performed. Sixty-nine studies …
Category Learning In Older Adulthood: Understanding And Reducing Age-Related Deficits, Rahel R. Rabi
Category Learning In Older Adulthood: Understanding And Reducing Age-Related Deficits, Rahel R. Rabi
Electronic Thesis and Dissertation Repository
Executive functions are important for learning rule-based (RB) categories, as well as non-rule-based (NRB) categories (e.g., categories learned implicitly, without a verbal rule). However, executive functioning is known to decline with age, leading to age-related deficits in category learning. The current thesis examines RB and NRB category learning in older adults using category sets that vary in difficulty (e.g., rule complexity, number of stimulus dimensions, salience of stimulus dimensions). In Chapter 2, older adults and younger adults completed three category sets (simple single-dimensional RB, disjunctive RB, and NRB). Older adults learned the simple, single-dimensional rules quite well. In contrast to …
An Investigation Of Masked Priming Mechanisms In Binary Classification Tasks, Jason Perry
An Investigation Of Masked Priming Mechanisms In Binary Classification Tasks, Jason Perry
Electronic Thesis and Dissertation Repository
The goal of the present research was to examine the nature of masked priming with an emphasis on the influence of stimulus-response (S-R) associations. In Chapter 2, both the magnitude of the category congruence (priming) effect and the nature of the priming distance effect were assessed in two number classification tasks. Participants made either magnitude (i.e., is the target larger or smaller than ‘5’?) or identification judgments (i.e., press one button if the target is a ‘1’, ‘2’, ‘3’ or ‘4’ or the other button if the target is a ‘6’, ‘7’, ‘8’ or ‘9’). Priming distance effects in …
