Question: What two dimensions are mentioned when looking into the theory of the American social psychologist, author, and lecturer born in 1972?

<P0-S0> Bernard Weiner (born 1935) is an American social psychologist known for developing a form of attribution theory which explains the emotional and motivational entailments of academic success and failure. <P0-S1>  Bernard Weiner got interested in the field of attribution after the first studying achievement motivation. <P0-S2>  He used TAT to identify differences in people’s achievement needs and then turned to the study of individual issues people face when they think of their own successes and failures. <P0-S3>  One of his students, Linda Beckman, came up with this topic, and from then on, Bernard Weiner carried on further investigation which led him to a road of the cognitive processes that have motivational influence. <P0-S4>  Being a three-stage process, attribution theory explains the causes of an event or behavior. <P0-S5>  The three stages include observations and determination of behavior, and attributing to causes. <P0-S6>  There are two types of attributions; external and internal. <P0-S7>  External attribution relates causality to outside agents, whereas, internal attribution assigns the person himself for any behavior. <P0-S8>  In one of his interviews in 1996, Bernard Weiner was asked the following: "How does attribution contribute to high ability, high achievement, and giftedness?" <P0-S9>  His answer is the proceeding paragraph. <SEP> <P1-S0>  Social groups are perceived as warm if they do not compete with the ingroup for the same resources (e.g., college space) and they are considered competent if they are high in status (e.g., economically or educationally successful). <P1-S1>  Thus, lack of competition predicts perceived warmth and status predicts perceived competence. <P1-S2>  The model was first proposed by social psychologist Susan Fiske and her colleagues Amy Cuddy, Peter Glick and Jun Xu. <P1-S3> The stereotype content model (SCM) is a psychological theory that hypothesizes that stereotypes possess two dimensions: warmth and competence. <SEP> <P2-S0> Amy Joy Casselberry Cuddy (born 1972) is an American social psychologist, author and lecturer known for her research on stereotyping and discrimination, emotions, power, nonverbal behavior, and the effects of social stimuli on hormone levels. <SEP> <P3-S0> Superfluidity and superconductivity are macroscopic manifestations of quantum mechanics. <P3-S1>  There is considerable interest, both theoretical and practical, in these quantum phase transitions. <P3-S2>  There has been a tremendous amount of work done in the field of phase transitions and critical phenomenon in two dimensions. <P3-S3>  Much of the interest in this field is because as the number of dimensions increases, the number of exactly solvable models diminishes drastically. <P3-S4>  In three or more dimensions one must resort to a mean field theory approach. <P3-S5>  The theory of superfluid transitions in two dimensions is known as the Kosterlitz-Thouless (KT) theory. <P3-S6>  The 2D XY model - where the order parameter is characterized by an amplitude and a phase - is the universality class for this transition.
