Psych/Soci Flashcards
(10 cards)
Flashbulb memory
The subjectively vivid, compelling memories of details associated with reception of news about emotionally arousing events were referred to as flashbulb memories
Episodic memory
It stores personally experienced episodes with tags for context and time
Cycle of worrying is an example of _________.
self-fulfilling prophecy
Another researcher suggests that the study should also include measures of a teacher’s academic standards as a component of the classroom learning environment. Which statement provides a possible reason for the researcher’s suggestion that is based on the concept of self-fulfilling prophecy?
A.If a teacher has low expectations, students are more likely to behave in a way that reinforces the teacher’s low standards.
B.If a teacher has high expectations, students are more likely to consider the teacher’s high standards to be unfair.
C.If a teacher has low expectations, students who overcome the teacher’s low standards are more likely to succeed.
D.If a teacher has high expectations, students are more likely to experience frustration from the teacher’s high standards.
The answer to this question is A because in a self-fulfilling prophecy, an observer’s expectations either directly or indirectly lead to the expected attributes or behavior. A teacher’s low expectations and low standards can cause students to behave in ways that then confirm the teacher’s low expectations (or standards).
PET scan is designed for____.
measuring brain activation in particular regions
A transient shortage of oxygen (global ischemia) releases excess glutamate into the extracellular fluid of the brain. This causes neuronal death by hyperexcitation to a greater extent in the hippocampus than in the cortex. Which reason best explains why the hippocampus is selectively vulnerable during global ischemia?
A.The magnitude of action potentials is greater in hippocampal than cortical neurons.
B.The expression of NMDA receptors is more abundant in hippocampal than cortical neurons.
C.Hippocampal neurons generate a more negative postsynaptic potential than cortical neurons.
D.Hippocampal synapses have faster neurotransmitter diffusion rates compared to cortical synapses.
The answer to this question is B because NMDA receptors are a subtype of glutamate receptor. Higher expression of NDMA receptors in the hippocampus than the cortex would render the hippocampus more vulnerable to the excess release of extracellular glutamate.
Five Factor model
The five factor model (FFM) is based on five personality factors, often referred to by the acronym OCEAN for Openness, Conscientiousness, Extraversion, Agreeableness and Neutroticism.
A.Acetylcholine
B.GABA
C.Endorphins
D.Serotonin
Know the roles of each
Motion parallax
objects moving at a constant speed across the frame will appear to move a greater amount if they are closer to an observer (or camera) than they would if they were at a greater distance.
Sensory interaction
Sensory interaction is the idea that one sensory modality (e.g., vision) may influence another (e.g., balance).
