The self-serving bias suggests that people tend to attribute their successes to internal, dispositional factors (such as ability or effort) while attributing their failures to external, situational factors. This bias helps maintain self-esteem and provides a sense of personal control over one's achievements.

According to Kelley's Covariation Model, for an external attribution, we look for high consensus, high distinctiveness, and high consistency. If a person acts differently in other situations (high distinctiveness), it supports an external attribution. The option C statement is logically complex in this context.

The actor-observer bias refers to the tendency to attribute one's own actions to external situational factors while attributing the actions of others to internal dispositional factors. In this specific scenario, the student explains their own performance based on the situation (the test's fairness) rather than their own effort, which aligns with the actor-observer perspective in social psychology.

An internal attribution occurs when an individual explains behavior by referring to the person's internal characteristics, such as personality traits, abilities, or dispositions. By labeling the child as lazy, the father is focusing on the child's inherent nature rather than external environmental factors like the quality of teaching or the difficulty of the schoolwork, thus making an internal attribution.

Empirical research in social psychology has extensively documented biases such as the fundamental attribution error (overemphasizing dispositional factors), the actor-observer effect (differing perspectives between actors and observers), and the self-serving bias (attributing success to self and failure to situation). The 'critical attribution error' is not a standard term or recognized phenomenon within established psychological literature.

Kelley's covariation model suggests that we attribute behavior based on consensus, distinctiveness, and consistency. If Sylvia laughs at all comedians, her behavior shows high consistency (she always does it) and low distinctiveness (she does it for all comedians, not just one). Therefore, both A and B are correct descriptors of her behavior within this theoretical framework.

In Weiner’s model, attributions are categorized by locus (internal vs. external) and stability (stable vs. unstable). Effort is considered an internal factor because it originates from the individual. It is also classified as unstable because effort is a variable that can change from one task or situation to another. Therefore, attributing failure to a lack of effort is an internal-unstable attribution.

The self-serving bias suggests that individuals tend to attribute their successes to internal, personal factors (dispositional), while attributing their failures to external, situational factors. This helps maintain self-esteem and a positive self-concept.

The fundamental attribution error describes the tendency to overemphasize personality traits and underemphasize situational factors when judging why someone else acted in a certain way. This cognitive bias is a cornerstone concept in social psychology regarding how we perceive and interpret human behavior.

The fundamental attribution error is a cognitive bias where observers overemphasize personality traits and underestimate situational influences when explaining the behavior of others. This tendency leads to inaccurate judgments about why people act the way they do, as it ignores the complex environmental pressures that often dictate human actions in specific contexts.
