Etiology | An active area of research that gives understanding of development and hopefully effective treatments |
Brain | two hemispheres connected by corpus callosum |
split-brain | awareness of both hemispheres as result of surgery to sever the corpus
callosum for severe epilepsy |
Forebrain | the largest part of the brain that conducts high-level processes such as
consciousness, cognition, emotion, reasoning, language and memory. Contains:
Cerebral cortex and Subcortical structures:
• Thalamus; Hypothalamus; Pituitary gland; Limbic system |
Cortex | outermost covering of the brain consisting of densely
packed neurons; responsible for higher thought processes and
interpretation of sensory input |
Cerebral hemispheres | the two sections of the cortex
on the left and right sides of the brain |
corpus callosum | thick band of neurons that connects
the right and left cerebral hemispheres |
Central Nervous System (CNS) | brain and spine column (fight or flight or freeze) |
Peripheral Nervous System (PNS) | nerves are messengers to CNS
• Somatic: conscious or voluntary activities |
autonomic | unconscious or involuntary activities (internal organs and glands) |
Frontal Lobe | thinking, emotions, personality, judgment, self-control, muscle control/movements, memory
storage, and controls your understanding of social norms |
Parietal Lobe | information from the body’s senses. Damage impairs emotional processing and arousal. |
Somatosensory cortex | sensory information from across the body, such as touch, temperature, and pain. |
Occipital Lobe | primary visual cortex |
Temporal Lobe | hearing, memory, emotion, and some aspects of language. |
Prefrontal Cortex | higher level cognitive functioning |
Thalamus | sensory relay for the brain (with exception of smell) |
Limbic System | processes emotion, memory and smell |
Hippocampus | learning and memory |
Amygdala | emotional connection to memories |
Hypothalamus | homeostatic process, body temperature, appetite, blood pressure,
sexual motivation and behavior |
Midbrain | structures deep within the brain |
Reticular formation | regulates the sleep/wake cycle, arousal, alertness, and motor activity |
Substantia nigra and ventral tegmental area (VTA) | critical for movement. Also responsible
for mood, reward, and addiction through production of dopamine. (deficit linked to
Parkinson’s Disease) |
Hindbrain | located at the back of the head and looks like an extension of the spinal cord |
Medulla | automatic processes of the autonomic nervous system (breathing, blood pressure,
and heart rate) pons, and cerebellum |
Pons (bridge) | serves to connect the hindbrain to the
rest of the brain; assists with regulation of brain activity during sleep. |
Cerebellum | coordinates voluntary muscle movements, balance and posture, and supports motor learning. |
Thalamus | The “gateway to the cortex” as input from most of
our sensory systems (vision, hearing, touch, and
taste) travels first to the thalamus |
Basal ganglia | Collection of large structures involved with
voluntary movement |
Amygdala | Appears to have a role in identifying,
remembering, and responding to fear and
aggression |
Hypothalamus | Involved with motivation and homeostasis, or the regulation of
body functions such as temperature, thirst, hunger, biological
rhythms, and sexual activities |
Hippocampus | Essential to the formation of long-term memories |
Cingulate cortex | ACC - important in decision making, emotion, anticipation of
reward, and empathy
• PCC - participates in memory and visual processing |
Nucleus accumbens | Important part of the brain’s reward and pleasure circuitry |
Neurotransmitters | the chemical messengers of the nervous system connect to receptors |
Agonists | chemicals that mimic a neurotransmitter at the receptor site. |
Antagonist | blocks or impedes the normal activity of a neurotransmitter at the receptor. |
Resting potential | state of the brain when not firing a neural impulse |
Action potential | release of the neural impulse that is a reversal of the electrical charge
in the axon that allows positive sodium ions to enter the cell. |
Acetylcholine | Muscle action, memory Increased arousal, enhanced cognition |
Beta-endorphin | Pain, pleasure Decreased anxiety, decreased tension |
Dopamine | Mood, sleep, learning Increased pleasure, suppressed appetite |
Gamma-aminobutyric acid (GABA) | Brain function, sleep Decreased anxiety, decreased tension |
Glutamate | Memory, learning Increased learning, enhanced memory |
Norepinephrine | Heart, intestines, alertness Increased arousal, suppressed appetite |
Serotonin | Mood, sleep, Modulated mood, suppressed appetite |
Classification | A system for describing the important categories, groups, or dimensions of disorder. Creates clinical utility, enhances communication among mental health professionals, and improves research efforts |
Reliability | Determines whether clinicians, using the same set of
criteria, classify children into the same clearly defined categories. |
Inter-rater reliability | two or more clinicians gathering different pieces
of information come to same diagnostic conclusion. |
Cross-time reliability | same diagnosis is reached if child is evaluated
(by same clinician) at two different time points. |
Validity | the classification gives true-to-life, meaningful information |
Internal validity | refers to the etiology of a disorder, or the core
patterns of symptoms or difficulties experienced. |
External Validity | refers to the implications of the disorder to
treatment |
Bottom-up process | (1) data collection from normal and abnormal
adjustment (2) statistical grouping by distresses and disfunctions into
dimensions. |
Top-down process | (1) identification of types of disorder (2)
specification of symptoms to disorder |
Dimensions of Disorders | (1) externalizing: under controlled
behaviors often directed at others (2) internalizing: over controlled
behaviors often directed toward the self. |
Developmental perspective | Disorders are conceptualized as delay, fixation, or deviance |
Homotypic | two or more within a classification system (ex: different types of anxiety) |
Heterotypic | two or more outside of same classification system (EX: depression
(internalizing) and conduct disorder (externalizing) |
Familial | two or more disorders are clinically related (EX: depression and substance use) |
Concurrent | experienced at the same time |
Successive | experienced after one another |
Methodology | informant-completed forms and the the tendency to report any and all negative symptoms |
Assessment | the systematic collection of relevant information to solve the issues of (1) differentiating everyday or transient difficulties from clinically significant psychopathology, and (2) classifying and caring for those who have been identified as having disorders. |
Primary Prevention | reducing or eliminating risks, and reduce the
incidence of disorder in children. (1) Universal: provided for entire population (2) Selective: groups in above-average risk (3) Indicated:
specific risk factors |
Secondary prevention | implemented when signs of distress/dysfunction are noted. |
Tertiary prevention | implemented when disorder is present |
Adaptive VS. Maladaptive | focus on effectiveness of actions; may not meet statistical deviance because of common occurrence; subjective perspective. |
Distress vs. Disability | also subjective perspective; (EX: “strive on stress” vs. “buckle under pressure) |
Dyscontrol vs. Dysregulation | emphasis on voluntary or involuntary |
Harmful Dysfunction | emphasis on evolutionary theory to explain psychopathology development |
Categories Model | use of DSM-5 and ICD-10 codes: categorical model with criterion; can be exclusionary (yes or no) |
Dimensional Model | a continuum; effective in study of personality historically with more research being done on other psychopathologies |

Multiculutral/diversity is a significant area of ungoing research: | Frameworks suggest: (1) use of client’s preferred language
(translator services) (2) therapist-client ethnic matching (3)
remove barriers to access (4) including family input where
appropriate (5) incorporation of cultural values (i.e. traditions,
religion, etc…) |
