Cousins of Neanderthals Left DNA in Africa, Scientists Report. The geneticists reached this conclusion, reported on Thursday in the journal Cell, after decoding the entire genome of three isolated hunter-gatherer peoples in Africa, hoping to cast light on the origins of modern human evolution.
But the finding is regarded skeptically by some paleoanthropologists because of the absence in the fossil record of anything that would support the geneticists’ statistical calculations. Two of the hunter-gatherers in the study, the Hadza and Sandawe of Tanzania, speak click languages and carry ancient DNA lineages that trace to the earliest branchings of the human family tree. The third group is that of the forest-dwelling pygmies of Cameroon, who also have ancient lineages and unusual blood types. The geneticists, led by Joseph Lachance and Sarah A. Tishkoff of the University of Pennsylvania, decoded the entire genomes of five men from each of these groups.
Among the DNA sequences special to pygmies, Dr. Dr. Dr. A co-author, Joshua M. Social psychology. Social psychologists therefore deal with the factors that lead us to behave in a given way in the presence of others, and look at the conditions under which certain behavior/actions and feelings occur.
Social psychology is concerned with the way these feelings, thoughts, beliefs, intentions and goals are constructed and how such psychological factors, in turn, influence our interactions with others. In addition to the split between psychology and sociology, there has been a somewhat less pronounced difference in emphasis between American social psychologists and European social psychologists. As a broad generalization, American researchers traditionally have focused more on the individual, whereas Europeans have paid more attention to group level phenomena (see group dynamics).[3][page needed] History[edit] Intrapersonal phenomena[edit] Attitudes[edit] Persuasion[edit] The topic of persuasion has received a great deal of attention in recent years.
Social cognition[edit] Self-concept[edit] Social influence. Morton Deutsch and Harold Gerard described two psychological needs that lead humans to conform to the expectations of others.
These include our need to be right (informational social influence), and our need to be liked (normative social influence).[3] Informational influence (or social proof) is an influence to accept information from another as evidence about reality. Informational influence comes into play when people are uncertain, either because stimuli are intrinsically ambiguous or because there is social disagreement. Normative influence is an influence to conform to the positive expectations of others. In terms of Kelman's typology, normative influence leads to public compliance, whereas informational influence leads to private acceptance. Types[edit] Social Influence is a broad term that relates to many different phenomena. Kelman's varieties[edit] 1) Compliance[edit] 2) Identification[edit] Philosophical anthropology. Sociology. What is the new sociology of Ideas ? A Discussion with Charles Camic and Neil Gross - Transeo Review.
Humanities are not so common an object of investigation for social scientists.
Other disciplines (intellectual history, political science or even philosophy) tend to challenge the accounts produced by sociologists. Moreover, the sophistication of disciplines such as philosophy or economic analysis can sometimes be a barrier for sociologists working on them. Could you briefly describe your personal trajectory, your education and past interests, and the reasons why you turned to the sociology of ideas ? Charles Camic : Although I “turned” about 10 years ago to using the expression “sociology of ideas” to describe my work, I’ve actually been doing research in this vein onward from my time in graduate school. When I was a sociology graduate student at the University of Chicago in the mid-1970s, my initial interests were social theory and the sociology of education. Neil Gross : You coined the phrase “new sociology of ideas” to describe the research field your works aim to contribute to.
