Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske Jul 2011

Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske

USF Tampa Graduate Theses and Dissertations

The contextual cueing effect was initially thought to be the product of memory guiding attention to the target location. However, the steep search slopes obtained in contextual cueing indicate an absence of attentional guidance. We hypothesized that crowding could be obscuring the presence of attentional guidance and investigated this possibility in 2 experiments. Crowding was manipulated by varying the density of items in the local target region in a contextual cueing task. We observed a significant reduction in search slopes between the novel and repeated conditions when crowding was reduced. Enhancing crowding eliminated the contextual cueing effect. These findings suggest …


Emotional Content In Autobiographical Memory Through An Attachment Theory Framework, Elizabeth Tsatkin May 2010

Emotional Content In Autobiographical Memory Through An Attachment Theory Framework, Elizabeth Tsatkin

Honors Scholar Theses

The current study investigates the relationship between individual differences in attachment style and the recall of autobiographical memories. According to attachment theory, affect regulation strategies employed by individuals high in attachment anxiety and high in attachment avoidance are likely to influence how information about the past is recalled. This study examines how attachment anxiety and attachment avoidance relate to the presence of negative emotions in autobiographical memories of upsetting events with important relationship figures (i.e., mother, father, or roommate). Participants included 248 undergraduate students ranging from ages 18-22 that attend a public university in the northeast. As hypothesized, individuals with …


The Effects Of Handedness And Bilateral Saccadic Eye Movements On False Alarms In Recognition Memory, Lisa Weinberg Apr 2010

The Effects Of Handedness And Bilateral Saccadic Eye Movements On False Alarms In Recognition Memory, Lisa Weinberg

Psychology Honors Projects

Handedness can be used as a marker for interhemispheric interaction, which can produce memory benefits. Bilateral saccadic eye movements can be used to manipulate levels of interhemispheric interaction. This study measured the effects of handedness and bilateral saccadic eye movement on memory using the Deese-Roediger-McDermott paradigm. This study predicted a memory advantage for left-handers and mixed-handers without eye movements and an advantage for right-handers with the eye movements. The results do not support these predictions but do suggest that handedness is a factor in episodic memory performance. The analyses for this study were run using A’ to compare false alarm …


Word Concreteness And Word Frequency As Moderators Of The Tip-Of-The-Tongue Effect, Jennifer Lynn Gianico Jan 2010

Word Concreteness And Word Frequency As Moderators Of The Tip-Of-The-Tongue Effect, Jennifer Lynn Gianico

Legacy Theses & Dissertations (2009 - 2024)

The tip-of-the-tongue (TOT) experience is a universal experience in which a speaker cannot fully produce a word that he or she believes will eventually be recalled and could easily be recognized. The purpose of the current set of experiments is to determine how different variables affect the rate of TOTs. Specifically, a series of three experiments investigates the roles of word concreteness and word frequency on TOT rates. A new finding, the concreteness effect on TOT rates, emerged and was replicated across all three experiments. This never-before investigated concreteness effect is discussed in terms of a general two-stage model of …


Modulation Of Memory Formation Following Violations Of Conditioned Expectations, Dennis Antonio Amodeo Jan 2009

Modulation Of Memory Formation Following Violations Of Conditioned Expectations, Dennis Antonio Amodeo

Theses Digitization Project

Increment in attention to the conditioned stimulus (CS) leads to an increased rate of acquisition of new associations involving CS. While the neuroanatomical basis of the phenomenon is largely understood, little is known about the synaptic mechanisms underlying memory formation for prediction error. The current experiment tests the overall hypothesis that this specific form of memory depends on N-methyl-D-aspartate (NMDA) receptor activation.


Memory Performance Is Related To Language Dominance As Determined By The Intracarotid Amobarbital Procedure, S. Kovac, G. Möddel, J. Reinholz, A. V. Alexopoulosa, T. Syed, S. U. Schuele, Tara T. Lineweaver, T. Loddenkemper Jan 2009

Memory Performance Is Related To Language Dominance As Determined By The Intracarotid Amobarbital Procedure, S. Kovac, G. Möddel, J. Reinholz, A. V. Alexopoulosa, T. Syed, S. U. Schuele, Tara T. Lineweaver, T. Loddenkemper

Scholarship and Professional Work - LAS

Objective

The goal of this study was to explore the relationship between language and memory lateralization in patients with epilepsy undergoing the intracarotid amobarbital procedure.

Methods

In 386 patients, language lateralization and memory lateralization as determined by laterality index (LI) were correlated with each other.

Results

Language lateralization and memory lateralization were positively correlated (r = 0.34, P < 0.01). Correlations differed depending on the presence and type of lesion (χ2 = 7.98, P < 0.05). LIs correlated significantly higher (z = 2.82, P < 0.05) in patients with cortical dysplasia (n = 41, r = 0.61, P < 0.01) compared with the group without lesions (n = 90, r = 0.16, P > 0.05), with patients with hippocampal sclerosis falling between these two groups. Both memory (P < 0.01) and language (P …


The Representation Of Multiple Translations In Bilingual Memory : An Examination Of Lexical Organization For Concrete, Abstract, And Emotion Words In Spanish-English Bilinguals, Dana M. Basnight-Brown Jan 2009

The Representation Of Multiple Translations In Bilingual Memory : An Examination Of Lexical Organization For Concrete, Abstract, And Emotion Words In Spanish-English Bilinguals, Dana M. Basnight-Brown

Legacy Theses & Dissertations (2009 - 2024)

Tokowicz and Kroll (2007) originally reported that the number of translations a word has across languages influences the speed with which bilinguals translate concrete and abstract words from one language to another. The current work examines how the number of translations that characterize a word influences bilingual lexical organization and the processing of concrete, abstract and emotional stimuli. Experiment 1 examined whether the number-of-translations effect reported previously could be obtained in a different task (i.e., lexical decision task) using the same materials presented by Tokowicz and Kroll. Decision latencies revealed no significant differences between concrete and abstract words, which suggested …


Memory For Music And The Implications Of Expertise For Music Recall: A Review ; Memory For The Recall Of Popular Songs: A Comparative Study Of Musicians And Nonmusicians, Simon Maclachlan Jan 2009

Memory For Music And The Implications Of Expertise For Music Recall: A Review ; Memory For The Recall Of Popular Songs: A Comparative Study Of Musicians And Nonmusicians, Simon Maclachlan

Theses : Honours

How people remember music is not only a practical concern for musicians, it also poses an interesting challenge for psychological theory (Wallace, 1994). One question that has often been overlooked is what occurs during the time that elapses between the stimulus onset (hearing music) and the generation of a response (an indication that the song has been remembered). While there is evidence to show that memory for song may be biased in a forward direction (Sibma, 2003), the role of expertise on memory for song may provide a deeper understanding of the nature of our memory for music. This review …


Directed Forgetting Of Live Motion Events: An Investigation Of A New Stimulus Set, Shawn Dickerson Jul 2008

Directed Forgetting Of Live Motion Events: An Investigation Of A New Stimulus Set, Shawn Dickerson

Psychology Theses & Dissertations

Instructions to forget presented information are often given and it is necessary to further understand how those involved can be affected by what is called "directed forgetting". The purpose of the current study was to investigate if a video stimuli would produce directed forgetting using the list method and a recognition style test. In addition, viewing live motion events has been suggested to be a more relevant modality to examine directed forgetting and thus another purpose of the current study was to utilize video stimuli to create a more valid assessment of this phenomenon. Participants (N=181) were selected through the …


The Relationships Among Age, Physical Activity, And Working Memory, Ellen M. Carpenter Jan 2008

The Relationships Among Age, Physical Activity, And Working Memory, Ellen M. Carpenter

Psychology Theses & Dissertations

As our population ages, determining exogenous factors that may offset cognitive decline become increasingly important. The primary goal of the present study was to determine whether older individuals who engage in regular physical activity demonstrate superior working memory performance relative to older sedentary individuals. Forty young (20 active, 20 sedentary) and forty older (20 active, 20 sedentary) individuals engaged in cognitive measures of information processing speed, inhibitory function, and verbal and visuospatial working memory. Age differences in recall were found for verbal and visuospatial span tasks, as well as for recall reaction time on verbal and visuospatial n-back tasks, and …


The Effects Of Using A Scripted Or Unscripted Interview In Forensic Interviews With Interpreters, Nicole Pruss Jan 2008

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 …


Cognitive Implications Of Facilitating Echoic Persistence, Carryl L. Baldwin Jan 2007

Cognitive Implications Of Facilitating Echoic Persistence, Carryl L. Baldwin

Psychology Faculty Publications

Seventeen participants performed a tone-pattern-matching task at different presentation levels while concurrently engaged in a simulated-driving task. Presentation levels of 60, 65, and 70 dBC (SPL) were combined factorially with tone-matching delays of 2, 3, and 4 sec. Intensity had no effect on performance in single-task conditions and short-delay conditions. However, when the participants were engaged concurrently in the driving task, a significant interaction between presentation level and delay was observed. In the longest delay condition, the participants performed the tone-patten-matching task more efficiently (more quickly and without additional errors) as presentation intensity increased. These findings demonstrate the interaction between …


Speeded Retrieval Abolishes The False Memory Suppression Effect: Evidence For The Distinctiveness Heuristic, C. S. Dodson, Amanda C. Gingerich Jan 2005

Speeded Retrieval Abolishes The False Memory Suppression Effect: Evidence For The Distinctiveness Heuristic, C. S. Dodson, Amanda C. Gingerich

Scholarship and Professional Work - LAS

We examined two different accounts of why studying distinctive information reduces false memories within the DRM paradigm. The impoverished relational encoding account predicts that less memorial information, such as overall famililarity, is elicited by the critical lure after distinctive encoding than after non-distinctive encoding. By contrast, the distinctiveness heuristic predicts that participants use a deliberate retrieval strategy to withhold responding to the critical lures. This retrieval strategy refers to a decision rule whereby the absence of memory for expected distinctive information is taken as evidence for an event’s nonoccurrence. We show that the typical false recognition suppression effect only occurs …


The Importance Of Retrieval Failures To Long-Term Retention: A Metacognitive Explanation Of The Spacing Effect, Harry P. Bahrick, Lynda K. Hall Jan 2005

The Importance Of Retrieval Failures To Long-Term Retention: A Metacognitive Explanation Of The Spacing Effect, Harry P. Bahrick, Lynda K. Hall

All Faculty and Staff Scholarship

Encoding strategies vary in their duration of effectiveness, and individuals can best identify and modify strategies that yield effects of short duration on the basis of retrieval failures. Multiple study sessions with long inter-session intervals are better than massed training at providing discriminative feedback that identifies encoding strategies of short duration. We report two investigations in which long intervals between study sessions yield substantial benefits to long-term retention, at a cost of only moderately longer individual study sessions. When individuals monitor and control encoding over an extended period, targets yielding the largest number of retrieval failures contribute substantially to the …


Musical Stem Completion: Humming That Note, Jill A. Warker, Andrea Halpern Jan 2005

Musical Stem Completion: Humming That Note, Jill A. Warker, Andrea Halpern

Faculty Journal Articles

This study looked at how people store and retrieve tonal music explicitly and implicitly using a production task. Participants completed an implicit task (tune stem completion) followed by an explicit task (cued recall). The tasks were identical except for the instructions at test time. They listened to tunes and were then presented with tune stems from previously heard tunes and novel tunes. For the implicit task, they were asked to sing a note they thought would come next musically. For the explicit task, they were asked to sing the note they remembered as coming next. Experiment 1 found that people …


Mental Concerts: Musical Imagery And Auditory Cortex, Robert J. Zatorre, Andrea R. Halpern Jan 2005

Mental Concerts: Musical Imagery And Auditory Cortex, Robert J. Zatorre, Andrea R. Halpern

Faculty Journal Articles

Most people intuitively understand what it means to “hear a tune in your head.” Converging evidence now indicates that auditory cortical areas can be recruited even in the absence of sound and that this corresponds to the phenomenological experience of imagining music. We discuss these findings as well as some methodological challenges. We also consider the role of core versus belt areas in musical imagery, the relation between auditory and motor systems during imagery of music performance, and practical implications of this research.


Why Distinctive Information Reduces False Memories: Evidence For Both Impoverished Relational-Encoding And Distinctiveness Heuristic Accounts, Amanda C. Gingerich, C. S. Dodson Jan 2004

Why Distinctive Information Reduces False Memories: Evidence For Both Impoverished Relational-Encoding And Distinctiveness Heuristic Accounts, Amanda C. Gingerich, C. S. Dodson

Scholarship and Professional Work - LAS

Two accounts explain why studying pictures reduces false memories within the Deese-Roediger-McDermott paradigm (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995). The impoverished relational-encoding account suggests that studying pictures interferes with the encoding of relational information, which is the primary basis for false memories in this paradigm. Alternatively, the distinctiveness heuristic assumes that critical lures are actively withheld by the use of a retrieval strategy. When participants were given inclusion recall instructions to report studied items as well as related items, they still reported critical lures less often after picture encoding than they did after word encoding. …


The Association Of Working Memory And Anxiety With Skill Acquisition And Transfer In Young And Older Adults, Isabelle Valk Jan 2004

The Association Of Working Memory And Anxiety With Skill Acquisition And Transfer In Young And Older Adults, Isabelle Valk

Theses: Doctorates and Masters

Two studies, involving a total of 184 adults between 17 and 89 years of age, were conducted to determine whether age differences in skill acquisition and transfer could be related to age differences in working memory functioning and anxiety. In both experiments, working memory functioning was measured using the Digit Span task (Wechsler, 1997) und the Reading Span tusk (Daneman & Carpenter, 1980), while anxiety levels were measured using the State Trait Anxiety Inventory (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983). Participants were required to perform a mental arithmetic task in Experiment I, and a visual numerosity task in Experiment …

International Bulletin of Political Psychology

This article identifies a complexity of helping others based on beliefs in the therapeutic value of such constructs as reliving memories, venting, catharsis, and the return of the repressed.


The Influence Of Warning Label Presentation In Memory Recognition Of Aging Adults, Brian J. Call Oct 2002

The Influence Of Warning Label Presentation In Memory Recognition Of Aging Adults, Brian J. Call

Master's Theses - Daytona Beach

Research indicates that hundreds of thousands of people are injured each year as a result of poor communication between medical personnel, warning label information, and consumers when taking over the counter or prescription medication. Typically, as adults age, they are increasingly responsible for remembering the hazards of taking medications. If inadequate information exists in memory in regards to side effects, dosage, and other warnings, the likelihood of improper usage will increase. Because aging adults typically have a reduction in cognitive resources, it was hypothesized that older adults would require the aid of additional warning information to assist in the retrieval …


Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling Jan 1998

Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling

Faculty Journal Articles

We explored the ability of older (60-80 years old) and younger (18-23 years old) musicians and nonmusicians to judge the similarity of transposed melodies varying on rhythm, mode, and/or contour (Experiment 1) and to discriminate among melodies differing only in rhythm, mode, or contour (Experiment 2). Similarity ratings did not vary greatly among groups, with tunes differing only by mode being rated as most similar. In the same/different discrimination task, musicians performed better than nonmusicians, but we found no age differences. We also found that discrimination of major from minor tunes was difficult for everyone, even for musicians. Mode is …

The Use Of Prior Knowledge In Learning From Examples, Stephen B. Blessing '89 Jul 1996

The Use Of Prior Knowledge In Learning From Examples, Stephen B. Blessing '89

Doctoral Dissertations

This dissertation examines the way people acquire procedures from examples, and provides a computational model of the results. In four experiments, people learned an analog of algebra. For each experiment, the initial know ledge that people had of the task was varied. In two experiments (Experiments 1 and 3), the syntactic know ledge that people had concerning the task w as manipulated. The knowledge of syntax that participants had, particularly the ability to correctly parse the character string, was found to be a major determiner in the way participants acquired the rules. Experiment 2 explicitly manipulated participant's awareness as to …


Short Term Effects Of Repeated Masked Priming In Stem Completion Tasks, Anthony Van Andel Jan 1995

Short Term Effects Of Repeated Masked Priming In Stem Completion Tasks, Anthony Van Andel

Theses : Honours

This thesis examines the effect of time delay and intervening items on masked repetition studies with word stem completion tasks. In the first experiment a masked priming effect was obtained. The effect was strongest 500ms after the presentation of the prime, and decreasing in a linear trend seven seconds after the presentation of the prime. The second experiment found that interpolating a naming task between the masked prime and the stem completion task eliminated the effects of the repeated masked prime. This result is a failure to replicate previous research which found a masked repetition effect over a short delay …


Memory Biases In Left Versus Right Implied Motion, Andrea R. Halpern, Michael H. Kelly Jan 1993

Memory Biases In Left Versus Right Implied Motion, Andrea R. Halpern, Michael H. Kelly

Faculty Journal Articles

People remember moving objects as having moved farther along in their path of motion than is actually the case; this is known as representational momentum (RM). Some authors have argued that RM is an internalization of environmental properties such as physical momentum and gravity. Five experiments demonstrated that a similar memory bias could not have been learned from the environment. For right-handed Ss, objects apparently moving to the right engendered a larger memory bias in the direction of motion than did those moving to the left. This effect, clearly not derived from real-world lateral asymmetries, was relatively insensitive to changes …


Mental Scanning In Auditory Imagery For Songs, Andrea R. Halpern Jan 1988

Mental Scanning In Auditory Imagery For Songs, Andrea R. Halpern

Faculty Journal Articles

Four experiments examined how people operate on memory representations of familiar songs. The tasks were similar to those used in studies of visual imagery. In one task, subjects saw a one-word lyric from a song and then saw a second lyric; then they had to say if the second lyric was from the same song as the first. In a second task, subjects mentally compared pitches of notes corresponding to song lyrics. In both tasks, reaction time increased as a function of the distance in beats between the two lyrics in the actual song, and in some conditions reaction time …

Incidental And Intentional Recall Of Item Names And Spatial Locations, Lois Ann Scovel Oct 1981

Incidental And Intentional Recall Of Item Names And Spatial Locations, Lois Ann Scovel

Psychology Theses & Dissertations

Recent studies have indicated that there are no differences between the incidental and intentional recall of spatial location; whereas, intentional recall is superior to incidental recall of verbal information. In order to examine the variables that affect recall, second graders, fifth graders and adults were instructed to learn the location or the name of seven highly discriminable or less discriminable objects presented in a spatial array. Analysis of names recalled indicated that high discriminability enhanced recall, and that intent to learn facilitated recall, particularly for adult males. Recall increased with age, and females recalled more names than did males. Analysis …


The Ability Of Young Children To Recognize Facial Photographs Of Young Children, Young Adults, And Senior Citizens, Barbara Bell Bruff Jul 1980

The Ability Of Young Children To Recognize Facial Photographs Of Young Children, Young Adults, And Senior Citizens, Barbara Bell Bruff

Psychology Theses & Dissertations

A review of the literature on facial recognition including a description of its development from birth to old age, hypothesized reasons for its unique development, and factors which affect it, reveals the need for facial recognition studies involving the young child. Twenty children (10 males, 10 females) at each of three ages (3, 5, and 7 years) were presented with 30 pictures of persons of both sexes from three age groups (3-7, 18-25, and 50 years and above). A testing procedure followed in which each child was asked to pick out the test picture from a photo album page with …


Normative Data On The Auditory Memory Test Battery, Mary Clare Mountain Jan 1980

Normative Data On The Auditory Memory Test Battery, Mary Clare Mountain

Dissertations and Theses

This study examined the means and standard deviations for the Auditory Memory Test Battery (Burford, 1976) using a sample of normal second, third, and fourth grade children. The study also compared span and sequence scores, low and high SES scores, and an individual's test scores with teacher judgment of intelligence group. A brief examination of the AMTB as used with LD children was also performed but not included in the statistical analysis.
