Cognitive-affective bases of behavior Flashcards
(112 cards)
_____________ deals with the observation that two individuals confronted with the same
stimulus presentation may come to different conclusions, that is, they may not
agree as to whether a simple stimulus was present. Disagreement may occur due
to differences in discriminability or response bias
Signal detection theory
process interpreting physical sensations
___________ of the stimulus is described by the mathematical function of separation/
spread, with separation representing signal strength and spread representing the
background noise present during the stimulus presentation.
Discriminability
d′
Response bias is a function of where the criterion for stimulus detection is set. The criterion can be set low to avoid _________ at a more
liberal threshold, or the criterion can be set high to avoid ____________ at a more
conservative threshold
False negatives; false positives
_____________ is the branch of psychology that deals with the detection and interpretation
of sensory stimuli.
Perception
__________ means that a perceived stimulus will undergo successive elaboration. For a
visual stimulus this means edge and orientation processing at early stages, the detection of features such as corners or curves or shapes at middle stages, and the identification of an object from a memory store at a later stage.
Hierarchical Processing
\_\_\_\_\_\_\_\_\_ means that there is a separate central nervous system unit for processing each visual feature (i.e., shape, color, and motion). Integration occurs by the simultaneous activity of processing units gaining access to each other’s contents (parallel and distributed processing).
Functional Segregation
_______________ defined as the cognitive process by which a unified internal representation of a
stimulus is formed from the activity of multiple mental modules. FB requires greater attentional resources than single feature processing, is
more likely to rely on the activity of the frontal and parietal cortex, and is supported
by cholinergic activity.
Feature Binding
____________ (Bayesian
approaches) has been used to understand sensory/perceptual processes (Brainard,
2009; Simoncelli, 2009). By applying optimal estimation theory (also known as
statistical decision theory) to a simple example, such as color recognition, we can
outline its basic principles and extrapolate to a more complex process such as
objection recognition.
optimal estimation theory
more recent than signal detection theory
Given several possible interpretations of a visual scene, the visual system selects the most probable interpretation a priori (Brainard et al., 2006),
or, put another way, the actual image data are combined with prior assumptions
(Brainard, 2009).
this is what is meant by Bayesian approaches, such as how we know the color of an object doesn’t change even though the lighting / environment may change.
Cocktail party effect
The term attention can
also mean a process occurring during alert states by which a stimulus can either
be attended to or ignored. (Selective attention).
___________ is a neuropsychological test often used to assess attention. Formulated by Michael Posner,[1] the task assesses an individual’s ability to perform an attentional shift. It has been used and modified to assess disorders, focal brain injury, and the effects of both on spatial attention.
The Posner cueing task, also known as the Posner paradigm
In the classic demonstration of a______________________, individuals who are actively tracking an aspect of a sports event fail to notice a person in a gorilla suit walking
directly through the game—clearly, attention cannot be directed everywhere.
Attentional blindness
when attentional resources are taxed through
increased processing load, or by dividing them between two tasks, performance
______ are observed; however, those resources can be increased through
practice (Treisman, 2009).
decrements
______ the more similar tasks are, the more they
compete
for limited attentional resources. Similar tasks tend to share the same
sensory/
perceptual modality.
Structural Interference
___________________there is a general limit to the extent of attentional resources.
Evidence for this limit can be found even when attention is divided between
two noninterfering (i.e., different modalities) tasks and performance decrements
occur. These decrements are less than those occurring with high structural interference,
but they are still meaningful enough to indicate a drain on a general
attentional resource that is occurring.
General Interference
______—the unity of our actions places limits on attentional
resources in preparing responses.
Behavioral coherence
_________ is an example of
attention to objects (i.e., word identity) taking precedence over attention to attributes
(i.e., the color of ink the word is printed in)
The Stroop Effect (Stroop, 1935)
________ helps to explain the push–pull relationship of the facilitative and inhibitory
mechanisms at work (Pinsk, Doninger, & Kastner, 2004). The theory posits the
degree to which an ignored stimulus is processed depends on the extent of processing
required by the attended stimulus. According to ____________, reduction of interference caused by distractors is greatest when the processing
demands to the attended stimulus are highest.
Attentional load theory (Lavie &
Tsal, 1994)
Attention can be “captured” in a stimulus-driven fashion, referred to as _______
mechanisms or reflexive attention, or in a strategic fashion, referred to as _______
mechanisms (Treisman, 2009).
bottom-up (odor of smoke, name said across a room); Gestalt
principles of perceptual organization (i.e., similarity, proximity, and common fate)
are part of bottom-up attentional influences (Kastner et al., 2009)
top-down (Anne Treisman’s conjunction search paradigm (Treisman & Gelade,
1980); find the O in red ink); lateral parietal and frontal
lobes; Top-down attentional
control helps to resolve competition between stimuli by introducing bias toward one stimulus over another.
Latent variable analysis suggests that _______ is a critical component of EFs, as there is a near perfect correlation of WM and non-WM executive
functioning tasks, leading some experts to refer to a unitary underlying construct
of executive attention
Working memory
“_____” EFs are thought to involve cognitive functions, whereas “___” EFs involve social and affective processing.
Cold; Hot; EFs are the only neuropsych tested constructs that relate to personality. (e.g., frontal lobe injury, HM).
Wisconsin Card Sort Test (set establishment and maintenance), the Stroop Color Word Test (attentional control), and the Controlled Oral Word Association Test
(verbal fluency).
______ viewed intelligence tests as probing the limited range of linguistic, logical, mathematical,
and spatial abilities, and so expanded to a theory of multiple intelligences to incorporate musical, bodily-kinesthetic, naturalistic, interpersonal and
intrapersonal abilities
Gardner
(compared to Stanford-Binet, Weschler, etc).
(Weschler: Intelligence is the aggregate or global capacity of the individual to act
purposefully, to think rationally and to deal effectively with his environment”)
_________ theory, from the bottom up are: (1) regulation of cortical
arousal and attention; (2) receiving, processing, and retention of information; and
(3) programming, regulation, and verification of behavior.
Luria’s (1980) theory of intelligence.
________ theorized that each mental ability represented by a mental test
was influenced by a general factor and a specific factor, which he designated as
lower case g and s
Spearman (same guy as ranked correlation -1 - +1).
