Vision neuroscience has made great strides in understanding the hierarchical organization of object representations along ventral visual stream (VVS). How VVS capture fine-grained similarities between objects that observers subjectively perceive received limited examination so far. In current study, we addressed this question by focussing on perceived among subordinate exemplars real-world categories. We hypothesized these are reflected with highest fidelity neural activity patterns...
Crime and violence are highly prevalent in South Africa, exacerbated by numerous socioeconomic challenges. To investigate how exposure to crime (and their impacts, e.g. stress) perceived low-income communities, we hosted a set of facilitated ‘community conversations’, as opportunities for community engagement. Our objective was provide safe space members share perceptions; were interested know if such conversations would be feasible with adolescents (>12 years) adults the community....
Threatening stimuli capture our attention more rapidly than benign stimuli, and threatening experiences lead to longer lasting vivid episodic memories. The common interpretation of these findings is that humans share an evolved fear response enables prioritized processing threats, providing a survival advantage. This assumed be universal; however, have been documented almost entirely in WEIRD (western, educated, industrialized, rich, democratic) populations. Here, we address this gap by...
Abstract Identifying what an object is, and whether has been encountered before, is a crucial aspect of human behavior. Despite this importance, we do not yet have complete understanding the neural basis these abilities. Investigations into organization representations revealed category specific in ventral visual stream perceptual tasks. Interestingly, categories fall within broader domains organization, with reported distinctions between animate, inanimate large, small objects. While there...
Perirhinal Cortex (PRC) in the medial temporal lobe has been proposed to be an extension of ventral visual stream (VVS; Murray, Bussey, Saksida, 2007). In support this notion, evidence from numerous sources suggests that PRC supports discrimination objects with high feature overlap. present fMRI study, we asked whether activity patterns reflect subjectively perceived similarity objects, and these are distinguishable at levels which earlier VVS regions cannot distinguish between them....
Threatening stimuli capture our attention more rapidly than benign stimuli, and threatening experiences lead to longer-lasting vivid episodic memories. The canonical interpretation of these findings is that humans share an evolved fear response enables prioritized processing providing a survival advantage. This assumed be universal,however, have been documented almost entirely in WEIRD (white, educated, industrialized, rich, democratic) populations. Here, we address this gap by examining...
How do we remember traumatic events, and are these memories different in individuals who experience post-traumatic stress? Some evidence suggests that events mnemonically enhanced, or include more episodic detail, relative to other types of memories. Simultaneously, with PTSD have non-episodic details all their memories, a pattern hypothesized result from impairment executive function. Here, explore questions unique population experienced severely than 20 years ago – lived through the 1994...
The threat superiority effect is the finding that threatening stimuli capture attention more rapidly than neutral stimuli. Despite its well-established presence, it unknown whether response impacted by our experience with or knowledge of threats. To explore this, we quantified individual differences in familiarity and for non-threatening stimuli, asked if these modulated on a visual search task. We found participants were faster at detecting they less familiar had of, but only items not...

The human adult hippocampus can be subdivided into the head, or anterior and its body tail, posterior hippocampus, a wealth of functional differences along longitudinal axis have been reported. One line literature emphasizes specialization for different aspects cognition, whereas another unique role in emotional processing. While some research suggests that memory between appear early development, it remains unclear whether this is also case emotion goal meta-analysis was to determine...
