Which cognitive bias might significantly impact the judgment of a school psychologist during assessments?

Confirmation bias is a cognitive bias that can significantly influence the judgment of a school psychologist during assessments by causing them to favor information that confirms their pre-existing beliefs or hypotheses while disregarding evidence that contradicts them. This bias can manifest when a psychologist has a suspicion about a student's needs or abilities; they may unconsciously select data or interpret observations in a way that supports their initial thoughts, potentially leading to skewed evaluation results.

In the context of psychological assessments, confirmation bias can affect not only how a school psychologist interprets test scores and behavioral observations but also impact decision-making regarding interventions and recommendations for the student. Awareness of this bias is crucial for psychologists to ensure that their evaluations are comprehensive, objective, and rooted in the best interests of the student, ensuring holistic understanding rather than one that reinforces preconceived notions.

Cognitive biases like attribution bias, availability heuristic, and anchoring bias can also play roles in decision-making, but confirmation bias is particularly prominent in assessment contexts where validating initial hypotheses can severely compromise accurate evaluation.
