"Nothing in Biology makes sense except in the light of evolution."
Theodosius Dobzhansky
Please note that this glossary is continuously updated and is being assembled piece by piece, and week by week, jumping from subject to subject, in no particular order. This is my personal list that I am assembling in order to assist me in my studies. It will primary deal with the brain, human emotions, behaviors -- and of course, with evolutionary terms. Feel feel to use this free listing, but if you can, please help us out with a purchase from this site of a Book, music CD, Video, or DVD available from Amazon.com to help defray the costs of this site -- use the search vehicle at the bottom of the page to take you to Amazon.com.

Authoritarian personality theory (APT) As a psychodynamic theory, APT theorized that authoritarianism resulted from childrearing practices that humiliated and deprecated the child and predicated parental affection on the child's immediate and unquestioning obedience to the parents.this kind of subjugating environment was thought to predispose children toward thinking of human relations in terms of dominance and submission and to teach a particular orientation toward hierarchy: the vilification of those thought of as weak, humane, or deviate (e.g. ethnic minorities) and the glorification of those perceived to be strong and powerful. As such, authoritarians were hypothesized to hold conservative economic and polical views, and also be generally xenophobic, racist, and ethnocentric. After Sidanius & Prato, Social Dominance, p.6,

These thoughts that we generate can then be stored for additional memory on the subject, or acted upon upon immediately in an outward physical movement. Consciousness is recategorized thoughts as opposed to reactions automatically generated by innate mechanisms reacting to the immediate environment. The common phrase, "Think before you act" applies here.
Creationism Theory that a supreme deity created all life and non-life forms in the universe.
Culture The accumulated knowledge of all that has come before us and which we thought to be important enough to pass to future generations. Culture can take the form of art, myth, buildings, landscaping, religions, music, language, philosophy, politics, sports, and technology.

Evolutionary
Psychology
The study of human
behavior based on adaptations over evolutionary time that produced modular mental
mechanisms in the brain. The field is still growing and split between those who
believe that culture has a large influence, (that's us at Evolution's Voyage), and
others who believe that culture has little or no influence because there was little
or no culture for most of Homo sapiens existence.
Evolutionary time lag Since evolution change occurs slowly, existing humans designed for the previous environments of which they are a product. Simply put: We carry around a stone-aged brain in a modern environment. After David Buss

The Frustration-Aggression Hypothesis Social psychological term meaning that the intention to deliberately harm others, ruslts from the individual's frustration at not achieving highly desired goals. The resulting anger, because it would be dangerous to aim it toward high-ranking individuals or institutions, is turned against less powerful others. Hate crimes easily fall into this category.

Greeting, submissive Primate term meaning greeting of a submissive to a dominate primate. When greeting a dominate, a male submissive utters a series of short, panting grunts know as pant-grunting or rapid-ohoh. While he utters these sounds a submissive assumes a position where he looks up at the individual he is greeting. The submissive may also make a series of deep bows which are repeated so quickly one after the other that this action is know as bobbing. The female submissive greets a dominate male by usually presenting her backside to the dominant ape to be inspected and sniffed. After Frans DeWaal
Greaser Derogative term used by dominate Anglos to characterize subordinate Latino-Americans. c. mid 1940's to c. 2000.
Grooming Primate behavior of searching through another primate's body hair for small insects. Process includes stroking, and consensus agrees that the activity has a calming affect on the primates and helps to encourage group interaction and intimacy. Speculative theory suggests that "gossip" -- the passing of intimate details surrounding one's interpersonal connections -- may have sprung from this close, calming activity.
Group A loose term meaning a gathering more than one individual that has some purpose for being. However, in an evolutionary perspective it means an alliance of individuals, with a dominate leader/s, compliant and/or cooperative associates, and a submissive follower/s that has a purpose for being together.

Theory attributed to William D. Hamilton, University of Oxford, 1964. Or, can be viewed as the sum of an individual's own reproductive success (classical fitness) plus the effects the individual's actions have on the reproductive success of his or her genetic relatives. After David Buss

Male sexual aggression. Identified to be composed of two paths: impersonal sex path, where males use sexual conquest as a source of peer status and self-esteem. The second: hostile masculinity path. Usually brought on by rejection by women, the males uses domination and controlling acts to derogate and subjugate their targets. After Malamuth, Sockloskie, Koss, & Tanaka.
Masturbation The self-manipulation of one's genitals in order to produce sexual pleasure.
Mate deprivation hypothesis. Men who have not, or cannot secure mates through the means of attraction experience deprivation, which prompts them to use sexually aggressive tactics to avoid being excluded entirely. After Lalumiere, Chalmers, Quinsey, & Seto. Also see Thornhill, Thornhill, & Dizinno.

Maternal Bonding The emotional attachment that develops between mother and infant within a few days after birth. After Linda Brannon
Mating opportunity costs Missed additional matings as a direct result of effort devoted to offspring. In summary, because the mating opportunity costs of parental care will generally be lower for males than for females, males will be less likely than females to take on parental care.
