Professional/Academic Experience

Paul Klaczynski has been on faculty in the School of Psychological Sciences at the University of Northern Colorado since 2007.

Research/Areas of Interest

Area of Interest

My research focuses on the development of critical thinking and the effects of beliefs stereotypes on children's, adolescents', and
adults' decisions, judgments, and reasoning. Within this broad area, I am interested in several specific belief systems—including, but
not limited to, beliefs about gender, occupations, and obesity—and how reliance on erroneous beliefs and stereotypes leads to biased
reasoning and judgments (known as "motivated," "belief-based," and "critical thinking" reasoning biases).

The focus of several recent studies has been on "developmental reversals": Counterintuitive age trends wherein children reason and
make better judgments than adolescents and adults. We have found that, when adolescent and adults reason and make decisions,
they often rely on misleading beliefs, stereotypes, and unreliable hearsay information, but children based their thinking on more reliable
statistical (numerical) evidence. As a consequence, children are—at least under certain conditions—better critical thinkers. This line of
research has led to an interest in identifying individual differences variables that let us predict which adolescents and adults reason
best. Our findings indicate that adolescents and adults who are (a) more flexible thinkers, (b) have greater "metacognitive
awareness" (for example, attend to their answers and strive for consistency), and (c) focus more on numerical than on social
evidence typically perform well. These findings do not diminish the importance of the developmental reversals we have found; instead,
they have allowed us to show that children only outperform adults (and adolescents) whose beliefs are entrenched and who are unable
(or unwilling) to consider different perspectives and ways of thinking.

We have studied developmental reversals in domains relevant to contemporary social issues including (but not limited to), gender,
juvenile delinquency, career decisions, and obesity. In two recent studies of judgments regarding gender and obese peers, our team
has found what appears to be an age-related increase in the "metacognitive gap." In evaluating the judgments they made of different
stereotype-relevant problems, children's evaluations correspond closely to their actual responses. However, despite being more likely to
respond incorrectly, adolescents and adults are also more likely to believe that they based their responses on sound logic. This is
what I have called the "metacognitive gap"—a contradiction in "thinking about one's own thinking" that, under some conditions,
increases with age. This phenomenon reveals a developmental pattern difficult to explain on the basis on most theories of critical
thinking and cognitive development.

Related to this research, I have also conducted several investigations of cross-cultural similarities and differences in preschoolers',
children's, and adolescents' perceptions of gender, obesity, and dieting/body image discrepancies, and how these perceptions relate to
numeracy and open-mindedness.

Teaching Philosophy

The core of my teaching philosophy is straightforward: Regardless of whether it is geared toward memorization, improvements in critical
thinking, or both, learning is an active process that evolves in, and interacts with, the subcultures of a university and its classrooms. I
rely on an apprenticeship metaphor of teaching and see students are “novices” at various levels of preparedness for acquiring the
“tools” of my trade. Through appropriate scaffolding, active guidance, encouragement to engage in self-initiated learning activities, and
individualized feedback, I hope to assist learners construct increasingly higher-order understandings of topical material. An essential
goal of facilitating the construction of these understandings is that their use is not tightly tied to the classroom; rather, students’
knowledge constructions should be sufficiently abstract that they transfer to other arenas (e.g., other classes, interactions with children,

The effective teacher should therefore engage the intellectual curiosity of students by creating an atmosphere of dialogue in which
students are guided toward increasingly accurate understandings of the "trade" and toward applying those understandings beyond the
walls of the classroom. Active participation on both the teacher's and the student's part is essential as knowledge and understanding
are created. Teaching thus represents the nexus of teacher, student, context, and course material.

Over the course of multiple interactions, students are challenged by the teacher and guided in their thinking through appropriate
feedback and a willingness to openly contemplate issues. In the ideal, the emergent outcome of this dialog is an active, independent
learner—a student who is interested in the pursuit of knowledge, who understands the constructive nature of knowledge and knowing,
and who strives toward achieving these goals without direct tuition.
