Midterm 1 Flashcards
Epiphysis
the closing of the ends of the bones, which terminates growth after the adolescent growth spurt has completed
Secondary sex characteristics
the manifestations of sexual maturity at puberty, including the development of breasts, the growth of facial and body hair, and changes in the voice
Taner Stages
a widely used system that describes the five stages of pubertal development
Secular trend
the tendency, over the past two centuries, for individuals to be larger in stature and to reach puberty earlier, primarily because of improvements in health and nutrition
Delayed phase preference
a pattern of sleep characterized by later sleep and wake times, which usually emerges during puberty
Basal metabolism rate
the minimal amount of energy the body uses using a resting state
Graduated driver licensing
system in which full adult driving privileges are not granted all at once, but over phased time
Deductive reasoning
a type of logical reasoning in which one draws logically necessary conclusions from a general set of premises or givens
Metacognition
thinking about thinking itself
imaginary audience
the belief, brought on by a heightened sense of self-consciousness of early adol. that everyone is watching and evaluating your behavior
Personal fable
the belief that they are unique and not subject to the rules that govern other peoples behavior
cognitive developmental view
a perspective on development, (Piaget), that takes a qualitative, stage theory approach
Sensorimotor period
(Cognitive developmental view, 1) birth ->2 yr
Preoperational period
(cognitive developmental view, 2) 2-5 yr
concrete operations
(cognitive developmental view, 3) 6-> early adol
Formal opperations
(cognitive developmental view, 4) adol through adulthood
information processing perspective
perspective on cognition that derives from the study of artificial intelligence and attempts to explain cognitive development in terms of growth of specific components of thinking process (such as memory)
Selective attention
the process by which we focus on one stimulus while tuning out the other
divided attention
the process of paying attention to two or more stimuli at the same time
Working memory
that aspect of memory in which information is held for a short period of time while a problem is being solved
long-term memory
the ability to recall something from a long time ago
autobiographical memory
the recall of personally meaningful past events
reminiscent bump
the fact that experiences from adolescence are generally recalled more than experiences from other stages of life
functional magnetic resonance imaging (fMRI)
used to produce images of the brain, often while the individual is preforming some sort of mental task
Diffusion tensor imaging
ised to produced images of the brain that shows connections among different regions
electroencephalography (EEG)
measures electrical activity at different locations of the scalp
Event-related potentials (ERPs)
Changes in electrical activity in areas of the brain in response to specific stimuli or events
Synaptic pruning
the process through which unnecessary connections between neurons are eliminated
Myelination
the process through which brain circuits are insulated with myelin, which improves the efficiency of information processing
Plasticity
the ability of the brain to change in response to experience
developmental plasticity
extensive remodeling of the brains circuitry in response to experiences during childhood and adol. while brain is still maturing
adult plasticity
relatively minor changes in brain circuits as a result of experiences during adulthood after the brain has matured
Prefrontal cortex
the region of the brain most important for sophisticated thinking abilities, such as planning, thinking ahead, weighing risks and rewards, and controlling impulses
Limbic system
an area of the brain that plays an important role in the processing of emotional experience, social information, and reward and punishment
Response inhibition
the suppression of a behavior that is inappropriate or no longer required
executive function
more advanced thinking abilities, enables chiefly by the maturation of the prefrontal cortex, especially in early adol
functional connectivity
the extent to which multiple brain regions function at the same time which improves during adol
Zone of proximal development
in Vygotsky’s theory, the level of challenge that is still within the individuals reach but that forces and individual to develop more advanced skills
