By Kenneth Anderson, MA Normal and Retrograde Neurotransmission Delta-9 THC (delta-9-tetrahydrocannabinol) and CBD (cannabidiol) are the two most commonly found cannabinoids in the cannabis plant. The plant contains over 100 other cannabinoids as well. THC and CBD both affect the endocannabinoid system. "Endo-" is a Greek prefix meaning "inside." "Endocannabinoid system" refers to all the systems of the body which contain cannabinoid receptors and are affected by cannabinoids. We will be primarily focused on the effects of cannabinoids in the central nervous system, and on the CB1 receptor, which is the main cannabinoid receptor there. Drugs like THC can affect the central nervous system because there are also naturally occurring cannabinoids in the central nervous system, the endo...

By Tom Horvath, PhD I expect that you know everything I am about to write about. However, I hope this blog will be a useful reminder about life and values. A well-lived life is based on values. We act on values we are not even aware of. However, we know many of them. Becoming even clearer about them is worth the effort. Some ways to accomplish that effort is what I am proposing here. If you find yourself, in some part of your life, uncertain about what to do next, it’s time to think ahead. What is a value you want to be acting on? To help identify this value, ask yourself “big picture” questions. What would I ultimately like to accomplish? How would I like to be remembered? What change seems most important to make? If I could be completely in charge, what would I do? What I ...

By Tom Horvath, PhD How well can I calm myself or energize myself using my own abilities? How much do I need to use a substance for help? Although at times a mild sedative (one drink) or mild stimulant (a cup of coffee) can be a helpful tool, the more we rely on such tools the more our internal abilities diminish (atrophy). Daily low doses of sedatives or stimulants can be helpful. As the doses get higher, problems can emerge. In cases of substantial addictive problems, it is common to see someone bouncing between “downers” and “uppers,” sometimes even multiple times per day. At that level of substance use we can lose all sense that self-regulation can be accomplished by ourselves. None of us may reach the ideal of regulating ourselves entirely from our own resources. However, ...

By Tom Horvath, PhD Boredom is the perception of being under-stimulated. We all have optimal levels of stimulation (some generally want more, some generally less). Whatever your level, when you are not getting enough, you are bored (and when over-stimulated, you may be stressed). Boredom is often considered an undesirable state. However, let’s start with its advantages. If not much is going on in your immediate world, you have time to consider the larger context of your life. It is easy to lose track of what is more important than day-to-day and moment-to-moment issues. If bored you have a moment to consider what is important, rather than just immediate or urgent. When feeling bored you might say, “I’m glad nothing is pressing on me at the moment; I can think about the bigger p...

By Tom Horvath, PhD This blog will focus less on physical skills (like playing the piano or hitting a baseball) and more on “psychological skills” like being assertive. Physical and psychological skills are not entirely distinct. Your body will need to play its part in a psychological skill. For instance, you would need to say “no thanks, I’m not interested in that” with your mouth. The physical skills needed to accomplish a psychological skill are typically already well known to you. You just need to use them! Without further ado, let's take a look at practicing psychological skills. Practicing Psychological Skills #1: Interpersonal Skills Nevertheless, the physical aspect of a psychological skill can be a good place to start. To stay with our example, you could practice sayin...

A Closer Look at the Rat Park Experiment, Part 2 By Kenneth Anderson, MA Part 1 reviewed some of the historical background which led up to the rat park studies. Part 2 reviews the rat park studies themselves. Part 3 will take a look at where we have gone since. Bruce K. Alexander's first rat park study was published in 1978. The subjects were 32 albino Wistar rats (18 males and 14 females). After weaning, 10 of the rats (six males and four females) were placed in solitary confinement in standard laboratory cages. Twenty-two of the rats (12 males and 10 females) were placed in rat park. Rat park was an open-topped plywood box with 95 square feet of floor space covered in sawdust where rats could play, fight, and have sex with each other just like they did in their natural enviro...

By Tom Horvath, PhD We regularly see criteria for evaluating our health, physical fitness, or financial well-being. If our relationships are the primary source of our emotional well-being (a statement apparently accurate for most people), then guidelines for evaluating our relationships would also be valuable. Having both one or a few intimates, and a wide range of other relationships, is conducive to well-being. We need to have one or a few people we know very well, and then many other relationships that could be meaningful in various ways. We can compare this situation to the specialist/generalist distinction. We need to be a specialist in one or a few areas (often to make a living), but we also need to have much general knowledge, to get along well in the world. The followin...

by Tom Horvath, PhD, ABPP Dialectical Behavior Therapy (DBT) places a primary focus on improving distress tolerance. One of several tools DBT offers for tolerating distress is radical acceptance. The context of using any of the distress tolerance tools is the recognition that life will have distress, and that we need to learn how to bear up under it. Life is worth living even if it can be painful. DBT distress tolerance skills are designed to help us get through a crisis, but these tools benefit from practice in advance. These skills can help us accept the discomfort or pain that occur in a crisis, while preventing that discomfort or pain from rising to the level of suffering. Radical = “going to the root,” like a radish. Radical acceptance does not mean we approve of reality. ...

by Tom Horvath, PhD, ABPP Dialectical is a word with a long history (back to the Greeks), but for now let’s define it as “focusing or acting on the interaction of opposing forces or ideas.” Dialectical Behavior Therapy (DBT) identifies and addresses three common dialectical dilemmas, in order to improve emotional self-regulation, one of the primary goals of DBT. DBT can be helpful for individuals in whom large and rapid emotional swings (e.g., from love to hate) are common, painful, and harmful. The first of the dialectical dilemmas involves being emotionally vulnerable (either at present, or over a lifetime as a result of being emotionally more sensitive than average), but then downplaying the intensity of emotions. Typical self-statements are “this won’t be that hard” or “I shou...

by Tom Horvath, PhD, ABPP Interpersonal boundaries are part of the rules we establish about how to interact with other people. We can compare interpersonal boundaries to being in a house. The house protects us from the outside, and on the inside we protect our warm or cool air, our possessions, and our privacy. Houses have walls, roofs, doors, windows, window coverings, pipes, wires, and vents, which allow us to be highly flexible about what comes in and what goes out. In this blog we focus on keeping inside what needs to stay in. In a parallel blog we focus on keeping outside what needs to stay out. In either case, I am the one ultimately responsible for managing the boundary. I need to be prepared for others who may not know or respect the boundary I have established. I need to kno...
