or summary of a particular event or type of stimulus. The third phase of information
processing involves storage of information in long-term memory. Long-term memory
consists of separate but connected categories. The final stage requires drawing on,
interpreting, and integrating categorical information to form judgments and decisions.
The social information process has profound managerial implications on hiring,
performance appraisal, leadership and communication.
The social information process is susceptible to various errors including halo, leniency,
central tendency, recency, and contract effects (see Table 7-2). Person perception also
is prone to the formation of stereotypes. A stereotype is an individual’s set of beliefs
about the characteristics or attributes of a group. Stereotypes may or may not be
accurate and are not always negative. Stereotyping is a four-step process that begins
by categorizing people into groups according to various criteria. Next, we infer that all
people within a particular group possess the same traits or characteristics. Then, we
form expectations of others and interpret their behavior according to our stereotypes.
Finally, stereotypes are maintained by (a) overestimating the frequency of stereotypic
behaviors exhibited by others, (b) incorrectly explaining expected and unexpected
behaviors, and (c) differentiating minority individuals from oneself. Stereotypes based
on sex-role, age, race, or disability may create biases in organizations. To reduce the
extent to which stereotypes influence decision making and interpersonal processes
throughout the organization, a firm should use education and training to inform its
workforce about the problem of stereotyping and it should engage in a broad effort to
reduce stereotyping through interpersonal contact among mixed groups. The firm
should use valid individual differences to differentiate successful performers and
remove promotional barriers. Top management commitment is needed to eliminate the
organizational practices that support or reinforce stereotyping and discriminatory
decisions.
People’s expectations or beliefs determine their behavior and performance through the
self-fulfilling prophecy and the Galatea effect, and thus serve to make their expectations
come true. The self-fulfilling prophecy occurs when someone’s high expectations for
another person result in high performance while the Galatea effect occurs when an
individual’s high self-expectations lead to high performance. Figure 7-2 presents a
model of the self-fulfilling prophecy showing how supervisory expectations affect
subordinate performance. First, high supervisory expectancy produces better
leadership, leading employees to develop higher self-expectations. Higher expectations
motivate employees to exert greater effort, ultimately increasing performance and
supervisory expectancies. Finally, successful performance also improves an
employee’s self-expectancy for achievement. Managers must harness the potential of
the self-fulfilling prophecy by building a hierarchical framework that reinforces positive
performance expectations.
Attribution theory holds that people attempt to infer causes for their own and others’
observed behavior. Kelley’s model of attribution is based on the premise that behavior
can be attributed to either internal factors within a person (e.g., ability) or to external
factors within the environment (e.g., task difficulty). To make attributions, we gather
information along three behavioral dimensions: consensus, distinctiveness, and
