Does Type Of Stimulus Influence Task-Irrelevant Evaluative Categorization Processes?, Guadalupe Corral

Open Access Theses & Dissertations

The effect of stimulus type on task-irrelevant evaluative categorization was examined in two separate studies by using the P3 component from event-related brain potentials. The first study presented idiosyncratic stimuli consisting of individuals that were rated by participants as either positive or negative within sequences of pictorial and verbal stimuli. The second study presented sequences of novel and familiar stimuli consisting of previously normed unattractive and neutral individuals. It was hypothesized that pictures would elicit task-irrelevant evaluative categorization processes and so would novel stimuli (relative to words and familiar stimuli, respectively). Task-irrelevance was examined by assessing P3 peak amplitude to …

The Distinctiveness Effect In Fingerprint Identification: How The Role Of Distinctiveness, Information Loss, And Informational Bias Influence Fingerprint Identification, Jessica L. Marcon

Open Access Theses & Dissertations

Fingerprint misidentification has become a concern for legal professionals, especially after the high profile misidentification of Brandon Mayfield as the Madrid train bomber and the first fingerprint related DNA exoneration of Stephen Cowans. The current studies examined how humans perceive the distinctiveness of fingerprints, whether distinctiveness effects found in face perception research are evident in fingerprint identification, and whether there are conditions under which the distinctiveness effect can be eliminated. Experiment 1 examined the distinctiveness effect and information loss, while Experiment 2 investigated the distinctiveness effect and its interaction with information loss and informational bias. In Experiment 1, results showed …

Attention Allocation And The Variability Of The Stereotype Priming Effect, Katherine R. White

Open Access Theses & Dissertations

The stereotype priming effect is assumed to be a rather uniform and robust effect. However, a closer look at the existing literature suggests that the `standard' stereotype priming effect may be more susceptible to variability than originally believed. In the present study, we sought to demonstrate that the stereotype priming effect displays significant variability in strength depending upon the level of attention allocated to the stereotype feature of interest. Participants were assigned to 1 of 3 conditions: a lexical decision task (LDT) condition, a pre-primed LDT condition, and a gender categorization condition. It was predicted that the stereotype priming effect …

Bilingual Lexical Disambiguation In Context: The Role Of Non-Selective Cross-Language Activation, Ana I. Schwartz, Li-Hao Yeh, Ana B. Areas Da Luz Fontes

Ana I Schwartz

The present study tested whether lexical disambiguation in sentence context is affected by cross-language lexical activation. In Experiment 1 Spanish-English bilinguals read English sentences biasing the subordinate meaning of homonyms that were either cognates or non-cognates. Participants’ ability to reject follow-up target words related to the dominant meaning showed greatest inhibition when the homonym was a cognate and the dominant meaning was shared with Spanish. In Experiment 2 a separate group of bilinguals read sentences biasing the dominant meaning of the homonyms and were instructed to accept target words related to any meaning of the homonym. In this case cognate …

On A Different Plane: Cross-Language Effects On The Conceptual Representations Of Within-Language Homonyms, Ana B. Areas, Ana I. Schwartz

Ana I Schwartz

We examined whether bilinguals’ conceptual representation of homonyms in one language are influenced by meanings in the other. 117 Spanish-English bilinguals generated sentences for 62 English homonyms that were also cognates with Spanish and which shared at least one meaning with Spanish (e.g., plane/plano). Production probabilities for each meaning were calculated. A stepwise multiple regression revealed that whether a meaning was shared with Spanish or not accounted for a significant portion of the variance, even after entering production probabilities from published monolingual norms. (Twilley et al., 1994). Homonyms classified as highly polarized based on monolingual responses became less polarized if …

Working Memory Influences On Cross-Language Activation During Bilingual Lexical Disambiguation, Ana B. Areas Da Luz Fontes, Ana I. Schwartz

Ana I Schwartz

This study investigated the role of verbal working memory on bilingual lexical disambiguation. Spanish-English bilinguals with low and high digit span read sentences in their second language ending in a cognate homonym (novel), noncognate homonym (fast), cognate (piano) or non-cognate (pencil). The dominant meanings of cognate homonyms were shared across languages while subordinate meanings were unique to the second language. Participants decided whether follow-up targets were related in meaning to the sentence. On critical trials sentences biased the subordinate meaning of the homonym and targets were related to the dominant meaning (novel – BOOK; fast – SPEED), forcing rejection of …

Getting To Know You: The Effects Of Familiarity And Time On Social Perception, Clarissa Arms Chavez

Open Access Theses & Dissertations

A new direction in social perception research is developed. The present research explored the impact of familiarity and time on social perception processes based on cognitive neuroscience models, social categorization models, and memory consolidation constructs. Familiarity was manipulated within an exposure task and time was manipulated by testing participants both 2-6 hr and 48 hr after the exposure task. Experiment 1 investigated the influence of familiarity and time on the argument of the automaticity of social categorization and associated stereotypes by testing the argument with two separate tasks. Experiment 1a tested the influence of familiarity and time on associated stereotypes …

Effects Of Concurrent Task Performance On Object Processing, Gabriela Durán

Open Access Theses & Dissertations

Most research on visual object identification focus on the bottom-up processes of the visual what? and where? pathways. However, such research has not been able to fully account for many visual abilities (e.g., identifying an object among many other objects and across changing conditions). Neurological evidence has shown that feedback from high-level areas (i.e., top-down processing) makes object processing more efficient. However, there are no behavioral studies that have tested this. Thus, four experiments used a concurrent n-back task to occupy higher-level areas and tested its effects on visual object processing relative to a number-repetition control task.

Experiment 1 examined …

The Effect Of Facial Resemblance On Alibi Credibility And Final Verdicts, Claudia Ochoa

Open Access Theses & Dissertations

The purpose of this study was to examine an extra-legal variable that may affect the credibility of a defendant and the alibi corroborator's testimonies. In this study, the facial appearance of the alibi corroborator was manipulated to resemble the defendant or the trial judge to different degrees using facial morphing software. Participants serving as mock jurors provided verdicts for a trial summary and rated the credibility of an alibi corroborator. It was hypothesized that as the facial resemblance shared between an alibi corroborator and a defendant increased, the less credible the alibi corroborator's testimony would be perceived, resulting in an …

A Study Of Possible Pre-Cognitive Advantages Of Bilingualism, Marisela Gutierrez

Open Access Theses & Dissertations

Past research has suggested that second language acquisition has a beneficial effect on the development of inhibitory control processes in children and adults. This has been referred to as the "bilingual advantage" and is most commonly quantified using the Simon task. Whether the bilingual advantage extends to precognitive mechanisms has not yet been examined. The goals of this study were to examine the bilingual advantage in university students; and to examine whether the bilingual advantage extends to the precognitive filtering mechanism of sensorimotor gating. It was predicted that, as compared to monolinguals, bilingual university students would have greater inhibitory control, …

The Effects Of Psychopathy And Machiavellianism On Cognitive Dissonance, Ashley Anne Murray

Open Access Theses & Dissertations

Psychopathic traits include a lack of guilt, a lack of remorse, callousness and antisocial behaviors such as impulsivity and aggression. The current study examined the effects of psychopathic traits as measured by the Psychopathic Personality Inventory - Revised: Short Form (PPI-R: SF; Lilienfeld & Widows, 2005) and the Levenson Primary and Secondary Psychopathy Scales (LPSP; Levenson, Kiehl, & Fitzpatrick, 1995), and of Machiavellianism (MACH), as measured by the MACH-IV (Christie & Geis, 1970), on cognitive dissonance in a sample of 164 participants. The induced compliance paradigm of cognitive dissonance was implemented by instructing each participant to complete a boring task …

Lexical Representation Of Second Language Words: Implications For Second Language Vocabulary Acquisition And Use, Ana I. Schwartz, Li-Hao Yeh, Moira P. Shaw

Ana I Schwartz

The goal of the present study was to examine whether cross-language activation of a bilingual’s native language influences the processing of lexical ambiguity within a second language. Highly proficient Spanish-English bilinguals performed a semantic verification task in which sentence frames were followed by the presentation of the final word of the sentence (the prime word). Participants then decided whether a follow-up target word was related to the meaning of the sentence. On critical trials the sentences ended in a semantically ambiguous word that was either a cognate with Spanish (e.g., novel), or a noncognate control matched on frequency and length …

Cross-Language Mediated Priming: Effects Of Context And Lexical Relationship, Ana I. Schwartz, Ana B. Areas Da Luz Fontes

Ana I Schwartz

We examined how linguistic context influences the nature of bilingual lexical activation. We hypothesized that in single-word context, form-related words would receive the strongest activation while, in sentence context, semantically related words would receive the strongest activation. Spanish-English bilinguals performed a semantic verification task on English target words preceded by a prime. On critical trials, the prime and target words were paired based either on a form-mediated relationship through the native language (L1), [e.g., bark (barco): BOAT] (Experiment 1) or on a semantically-mediated relationship [e.g., boat (barco): BARK] (Experiment 2). The prime word was presented either in isolation or after …

The Effects Of Using A Scripted Or Unscripted Interview In Forensic Interviews With Interpreters, Nicole Pruss

Open Access Theses & Dissertations

The current study set out to replicate and expand the results of a study by Pruss (2007) which found that information is lost when interviews are conducted through interpreters. In the present study, Viewers (i.e., mock eyewitnesses) fluent in Spanish watched a video of a burglary and then were interviewed in Spanish about what they had seen. Half of Viewers were randomly assigned to be interviewed by an English-speaking Interviewer through a bilingual Interpreter (Interpreter condition), and the other half were randomly assigned to be interviewed directly by a Spanish speaking Interviewer with no Interpreter (No Interpreter condition). Within each …

The N400 Erp: Semantic Vs. Evaluative Incongruities, Jennifer Hilda Taylor

Open Access Theses & Dissertations

The objective of this research was to utilize both behavioral (response times) and psychophysiological measures (ERPs - N400 & Pre-response Positivity) to uncover the cognitive mechanism responsible for the evaluative priming effect (spreading activation vs. response competition) by controlling for semantic influences. This research project examined the evaluative incongruity effect by controlling for semantic influences in two separate studies. The first study kept semantic associations among word pairs completely random, while the second study controlled for semantic associations by either pairing words from the same semantic category (e.g., animal-animal) or from different semantic categories (e.g., animal-person). Participants completed an evaluative …

Developing Lexical Competition Resolution Mechanisms Through Reading Experiences, Ana B. Areas Da Luz Fontes

Open Access Theses & Dissertations

The goal of the present study was to investigate whether competition resolution mechanisms are improved throughout a student's college years. For this purpose, I bilingual participants with a range in the number of college credits completed (e.g., freshmen to seniors) were recruited. Participants were presented with sentences that biased the less frequent, or subordinate meaning of an ambiguous word (e.g., novel, fast) (e.g., novel: something new; fast: to not eat). The ambiguous word was either a Spanish-English cognate (e.g., novel/novela) or a noncognate control (e.g., fast). These sentences were followed by target words that, on critical trials, were related to …

Reading Words In Spanish And English: Mapping Orthography To Phonology In Two Languages, Ana I. Schwartz, Judith F. Kroll, Michele Diaz

Ana I Schwartz

English-Spanish bilinguals named visually presented words aloud in each language. The words included cognates (e.g., fruit-fruta) and non-cognate translations, (e.g., pencil-lápiz). The cognates were selected so that the orthographic and phonological similarity of their lexical form in each language varied orthogonally. Cognate naming latencies were influenced by the cross-language match of the orthographic and phonological codes. When the orthographic forms were similar in the two languages, naming latencies were slowed by dissimilar phonology, providing evidence for feed-forward activation from orthography to phonology across languages. When the orthographic forms were dissimilar, the effects of the corresponding phonological match were not statistically …

Bilingual Lexical Activation In Sentence Context, Ana I. Schwartz, Judith F. Kroll

Ana I Schwartz

The present study investigated the cognitive nature of second language (L2) lexical processing in sentence context. We examined bilinguals’ L2 word recognition performance for language-ambiguous words [cognates (e.g., piano); and homographs (e.g., pan)] in two sentence context experiments with highly proficient Spanish-English bilinguals living in a bilingual community (Experiment 1) and with intermediate proficiency Spanish-English bilinguals living in a monolingual community (Experiment 2). To determine the influence of sentence constraint on cross-language activation, the critical words and their matched controls were inserted in low- and high-constraint sentences. In low-constraint sentences significant cognate facilitation was observed, suggesting that both languages were …
