Eyewitness Choosing Behavior: The Role Of Ecphoric Experience And Non-Memorial Cues, Brian S. Cahill
Eyewitness Choosing Behavior: The Role Of Ecphoric Experience And Non-Memorial Cues, Brian S. Cahill
FIU Electronic Theses and Dissertations
Researchers’ attempts at understanding the processes underlying witness choosing behavior have focused on applying models that predict that identifications will be primarily driven by memorial factors. However, research has shown that several non-memorial variables affect witness choosing behavior (e.g., administrator influence, clothing bias, co-witness information); thus a full understanding of the processes underlying witness choosing behavior needs to account for these effects. While the memory-based models do attempt to provide explanations for the effects of non-memorial based variables on choosing behavior they all do so within a memorial context. However, I will argue a lineup task is not simply a …

Brain and Mind Institute Researchers' Publications
Many attempts have been made to localize the physical trace of a memory, or engram, in the brain. However, until recently, engrams have remained largely elusive. In this Review, we develop four defining criteria that enable us to critically assess the recent progress that has been made towards finding the engram. Recent 'capture' studies use novel approaches to tag populations of neurons that are active during memory encoding, thereby allowing these engram-associated neurons to be manipulated at later times. We propose that findings from these capture studies represent considerable progress in allowing us to observe, erase and express the engram.
Working With Embroideries And Counter-Maps: Engaging Memory And Imagination Within Decolonizing Frameworks, Puleng Segalo, Einat Manoff, Michelle Fine
Working With Embroideries And Counter-Maps: Engaging Memory And Imagination Within Decolonizing Frameworks, Puleng Segalo, Einat Manoff, Michelle Fine
Publications and Research
As people around the world continue to have their voices, desires, and movements restricted, and their pasts and futures told on their behalf, we are interested in the critical project of decolonizing, which involves contesting dominant narratives and hegemonic representations. Ignacio Martín - Baró called these the “collective lies” told about people and politics. This essay reflects within and across two sites of injustice, located in Israel/Palestine and in South Africa, to excavate the circuits of structural violence, internalized colonization and possible reworking of those toward resistance that can be revealed within the stubborn particulars of place, history, and culture. …
Building Metamemorial Knowledge Over Time: Insights From Eye Tracking About The Bases Of Feeling-Of-Knowing And Confidence Judgements, Elizabeth F. Chua, Lisa A. Solinger
Building Metamemorial Knowledge Over Time: Insights From Eye Tracking About The Bases Of Feeling-Of-Knowing And Confidence Judgements, Elizabeth F. Chua, Lisa A. Solinger
Publications and Research
Metamemory processes depend on different factors across the learning and memory time-scale. In the laboratory, subjects are often asked to make prospective feeling-of-knowing (FOK) judgments about target retrievability, or are asked to make retrospective confidence judgments (RCJs) about the retrieved target. We examined distinct and shared contributors to metamemory judgments, and how they were built over time. Eye movements were monitored during a face-scene associative memory task. At test, participants viewed a studied scene, then rated their FOK that they would remember the associated face. This was followed by a forced choice recognition test and RCJs. FOK judgments were less …
Contrasting Styles In Cognition And Behaviour In Bumblebees And Honeybees., David F Sherry, Caroline G Strang
Contrasting Styles In Cognition And Behaviour In Bumblebees And Honeybees., David F Sherry, Caroline G Strang
Psychology Publications
Bumblebees and honeybees have been the subjects of a great deal of recent research in animal cognition. Many of the major topics in cognition, including memory, attention, concept learning, numerosity, spatial cognition, timing, social learning, and metacognition have been examined in bumblebees, honeybees, or both. Although bumblebees and honeybees are very closely related, they also differ in important ways, including social organization, development, and foraging behaviour. We examine whether differences between bumblebees and honeybees in cognitive processes are related to differences in their natural history and behaviour. There are differences in some cognitive traits, such as serial reversal learning and …
Attentional Competition: Weapon Focus, Encoding Time, And Memory Accuracy Correlations Between Crime Scene Items, Seyram Kekessie
Attentional Competition: Weapon Focus, Encoding Time, And Memory Accuracy Correlations Between Crime Scene Items, Seyram Kekessie
FIU Electronic Theses and Dissertations
The present study examines the relationships between recognition and recall accuracy of faces, and recognition and recall accuracy of objects. Secondly, this study examines the influence of weapon presence on description and identification accuracy, and whether encoding time moderates the effect. 713 participants watched an image that was either displayed for five seconds or twenty seconds, and either included a weapon or no weapon. Subsequently, they were asked to give descriptions of what they saw before viewing a lineup that either included the perpetrator or was made up of innocent suspects. Results indicated that witnesses’ description accuracy of the crime …
Bisphenol-A Exposure During Adolescence Leads To Enduring Alterations In Cognition And Dendritic Spine Density In Adult Male And Female Rats, Rachel E. Bowman, Victoria N. Luine, Samantha Diaz Weinstein, Hameda Khandaker, Sarah Dewolf, Maya Frankfurt
Bisphenol-A Exposure During Adolescence Leads To Enduring Alterations In Cognition And Dendritic Spine Density In Adult Male And Female Rats, Rachel E. Bowman, Victoria N. Luine, Samantha Diaz Weinstein, Hameda Khandaker, Sarah Dewolf, Maya Frankfurt
Psychology Faculty Publications
We have previously demonstrated that adolescent exposure of rats to bisphenol-A (BPA), an environmental endocrine disrupter, increases anxiety, impairs spatial memory, and decreases dendritic spine density in the CA1 region of the hippocampus (CA1) and medial prefrontal cortex (mPFC) when measured in adolescence in both sexes. The present study examined whether the behavioral and morphological alterations following BPA exposure during adolescent development are maintained into adulthood. Male and female, adolescent rats received BPA, 40 μg/kg/bodyweight, or control treatments for one week. In adulthood, subjects were tested for anxiety and locomotor activity, spatial memory, non-spatial visual memory, and sucrose preference. Additionally, …
Hippocampal Volume And Auditory Attention On A Verbal Memory Task With Adult Survivors Of Pediatric Brain Tumor, Reema Jayakar, Tricia Z. King, Robin Morris, Sabrina Na
Hippocampal Volume And Auditory Attention On A Verbal Memory Task With Adult Survivors Of Pediatric Brain Tumor, Reema Jayakar, Tricia Z. King, Robin Morris, Sabrina Na
Psychology Faculty Publications
Objective: We examined the nature of verbal memory deficits and the possible hippocampal underpinnings in long-term adult survivors of childhood brain tumor. Method: 35 survivors (M=24.10±4.93 years at testing; 54% female), on average 15 years post-diagnosis, and 59 typically developing adults (M=22.40±4.35 years, 54% female) participated. Automated FMRIB Software Library (FSL) tools were used to measure hippocampal, putamen, and whole brain volumes. The California Verbal Learning Test – Second Edition (CVLT-II) was used to assess verbal memory. Results: Hippocampal (F(1,91)=4.06, ηp2=.04), putamen (F(1,91)=11.18, ηp2=.11), and whole brain (F(1,92)=18.51, …
Effects Of Caffeine On Memory In Rats, Cisse Nakeyar
Effects Of Caffeine On Memory In Rats, Cisse Nakeyar
2015 Undergraduate Awards
Caffeine is typically used to counter the effects of fatigue by enhancing performance for cognitive tasks, it is also known to suppress appetite. The current study is conducted to determine if caffeine would have an effect on memory. Twenty-four male Long Evans rats (375-425g) were used, they were randomly assigned to one of three groups: saline control (0.9% saline), caffeine low dose (15mg/kg), and caffeine high dose (50mg/kg). Testing was conducted in a Skinner box with a retractable lever that dispensed food when pressed. Rats were trained for five consecutive days for 10-15 min sessions. Then, two days of baseline …
