exam Flashcards
what is the subcorticle structure associated with the experience of arousal, alertness and wakefulness?
the reticular formation
what subcorticle brain structure produces and releases dopamine?
the ventral tegmental area
what cortical brain structure stores and processes the reward related values of objects and events?
the orbitofrontal cortex
what is the structure in the brain stem involved in motivational and emotional functioning?
the reticular formation
what are the 8 subcortical brain structures involved in motivation and emotion functioning?
reticular formation, basal ganglia, amygdala, hypothalamus, insular cortex, ventral tegmental area, ventral striatum, nucleus accumbens
what are the 5 cortical structures involved in motivation and emotion?
prefronal cortex, orbitofrontal cortex, ventromedial prefrontal cortex, dorsolateral prefrontal cortex, anterior cingulate cortex
describe the dopamine based reward circuit/ the brains reward system
beginning in the ventral tegmental area (VTA) where dopamine is manufactured and then released to the nucleus accumbens (NA). From the NA, the reward center extends into the prefrontal cortex, which is involved in the subjective experience of pleasure, and into the orbitofrontal cortex, which stores the objects learned reward value
what does the hypothalamus do?
the hypothalamus regulates eating, drinking, mating, and the endocrine system. it controls the pituitary gland which regulates the endocrine system. its the brain of the autonomic nervous system.
what were the 3 philosophical origins of motivational concepts, or the 3 grand theories?
will, instinct and drive
the grand theory of will proposed that?
the ancient philosophers understood motivation within 2 themes: good, rational, immaterial and active (i.e. the will); and primitive, impulsive, biological and reactive (i.e. bodily desires).
the grand theory of instinct proposed that?
physiological analysis of motivation by focusing on the mechanistic. the appeal of instinct doctrine was its ability to explain unlearned behaviour that had energy and purpose (i.e. goal directed biological impulses)
the grand theory of drive proposes that?
behaviour is motivated to the extent that it serves the needs of the organism and restores biological homeostatis.
what is a paradigm?
a consensus about what constitutes a disciplines methods, problems, and solutions. it is a stage in the typical development of a scientific discipline.
what is motivations new paradigm?
one in which behaviour is energised and directed not by one single grand cause, but instead by a multitude of multilevel and co-acting influences
what are 3 principles to keep in mind when studying the motivated and emotional brain?
1: specific brain structures generate specific motivational states;
2: biochemical agents (ie NT’s) stimulate these brain structures;
3: day to day events stimulate biochemical agents into action
define the process of the motivated brain?
An environmental event stimulates the release of biochemical agents that stimulate brain structures which in turn arouses motivation
motivation involves those processes that give behaviour its _________ and _____________
energy and direction
a behaviours energy is its what?
strength, intensity and persistence
a persons motivation can be expressed through their?
behaviour, engagement, brain and physiological activations, and self report
what are the 7 behavioural expressions of motivation
effort, persistence, latency, choice, probability of response, facial expressions, and bodily gestures
what are the 4 interrelated aspects of engagement?
behaviour, emotion, cognition, and agency
what brain and physiological activity are expressions of motivation?
brain activity, cardiovascular activity, hormonal activity, ocular activity, electrodermal activity, skeletal activity
what is the framework for understanding motivation and emotion?
antecedent conditions cue a motive status that is influenced by ones needs, cognitions and emotions. this leads to a sense of “wanting to” and an urge to either approach or avoid which energises and directs ones behaviour
what are the 4 processes capable of giving behaviour strength and purpose (its energy and direction)?
the individuals needs, cognitions, emotions, and external events
what are the relationship and social context factors that involve and satisfy ones need for relatedness?
social interactions that promise the possibility of warmth, care, and mutual concern vitalise ones need for relatedness. Having relationships that involve mutual caring, liking, accepting and valuing satisfy ones need for relatedness.
what is engagement?
engagement refers to how actively involved a person is in a task. it is a multidimensional construct consisting of 4 distinct, yet intercorrelated and mutually supportive, aspects of behaviour, emotion, cognition, and agency
what is cognitive engagement?
cognitive engagement refers to how strategically the person attempts to process information and to learn in terms of employing sophisticated rather than superficial learning strategies.
