Visual tracking of multiple objects in a complex scene is a critical survival skill. When we attempt to safely cross a busy street, follow a ball's position during a sporting event, or monitor children in a busy playground, we rely on our brain's capacity to selectively attend to and track the position of specific objects in a dynamic scene. This…

Two mechanisms are said to be responsible for guiding focal attention in visual selection: bottom-up, saliency-driven capture and top-down control. These mechanisms were examined with a paradigm that combined a visual search task with postdisplay probe detection. Two SOAs between the search display and probe onsets were introduced to investigate…

Purpose: To investigate the perception and production of lexical stress and processing of affective prosody in adolescents with high-functioning autism (HFA). We hypothesized preserved processing of lexical and affective prosody but atypical lexical prosody production. Method: Sixteen children with HFA and 15 typically developing (TD) peers…

This dissertation attempts to explain how nineteenth-century American Spiritualist literature may have made readers feel like they were hearing voices, touching the dead, seeing celestial spaces, or enjoying other sensory proofs of the afterlife. Spiritualists believed that, while all human beings possessed faculties designed to perceive the dead,…

Dyslexia is a neuro-cognitive disorder with a strong genetic basis, characterized by a difficulty in acquiring reading skills. Several hypotheses have been suggested in an attempt to explain the origin of dyslexia, among which some have suggested that dyslexic readers might have a deficit in auditory temporal processing, while others hypothesized…

Mindfulness is a key skill that produces the greater psychological awareness identified by most leadership scholars as being essential to effective leadership. This study conducted an exploratory assessment of the effectiveness of mindfulness-based cocurricular collegiate leadership programs through pre- and post-participation application of the…

The goal of this study was to explore whether viewing the speaker's articulatory gestures contributes to lexical access in children (ages 5-10) and in adults. We conducted a vowel monitoring task with words and pseudo-words in audio-only (AO) and audiovisual (AV) contexts with white noise masking the acoustic signal. The results indicated that…

Perceived age plays an important role in the context of age identity and social interactions. To examine how accurate individuals are in estimating how old they look and how old others are, younger, middle-aged, and older adults rated photographs of older target persons (for whom we had information about objective and subjective age) in terms of…

The present study investigates how age, phonological saliency, and deviance size affect the presence of mismatch negativity (MMN) and positive mismatch response (P-MMR). This work measured the auditory mismatch responses to Mandarin lexical tones, initial consonants, and vowels in 4- to 6-year-old preschoolers using the multiple-deviant oddball…

Paired associates learning is impaired in both schizophrenia and amnestic mild cognitive impairment (aMCI), which may reflect hippocampal pathology. In addition, schizophrenia is characterized by the dysfunction of the retino-geniculo-striatal magnocellular (M) visual pathway. The purpose of this study was to investigate the interaction between…

Purpose: In this study, the authors evaluated the effect of remote system and acoustic environment on speech perception via telehealth with cochlear implant recipients. Method: Speech perception was measured in quiet and in noise. Systems evaluated were Polycom visual concert (PVC) and a hybrid presentation system (HPS). Each system was evaluated…

This paper applies contemporary principles in cognitive and social psychology to understand how Western ballet and modern dance is imbued with emotional and narrative meaning by an audience. These include nine Gestalt concepts of visual form perception as well as cognitive heuristics of representativeness and availability in concept formation and…

The present work examined whether secrets are experienced as physical burdens, thereby influencing perception and action. Four studies examined the behavior of people who harbored important secrets, such as secrets concerning infidelity and sexual orientation. People who recalled, were preoccupied with, or suppressed an important secret estimated…

The Japanese language has single/geminate obstruents characterized by durational difference in closure/frication as part of the phonemic repertoire used to distinguish word meanings. We first evaluated infants' abilities to discriminate naturally uttered single/geminate obstruents (/pata/ and /patta/) using the visual habituation-dishabituation…

Early studies of memory-impaired patients with medial temporal lobe (MTL) damage led to the view that the hippocampus and related MTL structures are involved in the formation of long-term memory and that immediate memory and working memory are independent of these structures. This traditional idea has recently been revisited. Impaired performance…
