In this video I explain the 4 remaining "sins" of memory from Daniel Schacter's list. Misattribution refers to incorrectly identifying the source of a memory and relates to false recognition, deja vu, and cryptomnesia. Suggestibility is the idea that our memories are subject to influence and distortion from external information. Several types of bias can influence memory, including consistency bias and egocentric bias. Persistence refers to repeated recall of memories of traumatic events that disrupts one's life and is related to disoders like PTSD.

Please note that the symptoms described in this video are not comprehensive and there are other symptoms involved in diagnosis for each of these disorders.

In this video I explain external validity (or ecological validity) and criticisms of artificiality that can arise from laboratory experimentation. I also explain naturalistic observation and field experiments as ways of overcoming artificiality and collecting real-life data, though both of these approaches have the disadvantage of sacrificing control over potential confounding variables.

In this video I describe characteristics that are important for determining whether traits or behaviors represent potential symptoms of a disorder. These mostly focus on deviance, dysfunction, and distress, though danger and duration also play a role in identifying symptoms. Next I discuss the challenges of diagnosis and the need to find a balance between objectivity and the inherently subjective nature of the psychiatrist-client relationship.

In this video I discuss some ways that drugs can influence the functioning of neurotransmitters by binding to receptors on postsynaptic neurons. I explain the difference between agonist drugs which increase effects of a neurotransmitter and antagonist drugs which reduce the effects of the neurotransmitter. I explain how nicotine acts as an agonist for the neurotransmitter acetylcholine and how neuroadaptation relates to addiction. Next I explain how caffeine acts an an antagonist for the neurotransmitter adenosine and how this relates to the familiar "crash" that people experience after using caffeine.

In this video I describe touch sensation and haptic perception, which refers to exploring the world by grasping. I outline the types of receptor in the skin including mechanoreceptors, thermoreceptors, and nocireceptors, and then discuss how signals are mapped out according to sensitivity in the somatosensory cortex of the parietal lobe. This mapping research was initially conducted by Wilder Penfield and can be used to create a “homunculus” or a representation of a little person in the cortex, which can be done for both the somatosensory cortex and the motor cortex.

In this video I consider racial differences in average IQ scores. This controversy reached a peak with the publication of "The Bell Curve" by Richard Herrnstein and Charles Murray in 1994. This led to publication of several papers on race and IQ stating that IQ is considered valid, reliable, and heritable, and that while group differences exist, the causes of these differences are not clearly understood. While concepts of race, environmental and societal forces, and genes may or may not all contribute to observed differences between groups, it's important to remember that knowing an individual's group membership doesn't tell one anything about that individual's IQ score.
