    Effects of Age-Related Stereotype Threat on Metacognition.Natasha Y. Fourquet, Tara K. Patterson, Changrui Li, Alan D. Castel & Barbara J. Knowlton - 2020 - Frontiers in Psychology 11.
    Previous work has shown that memory performance in older adults is affected by activation of a stereotype of age-related memory decline. In the present experiment, we examined whether stereotype threat would affect metamemory in older adults; that is, whether under stereotype threat they make poorer judgments about what they could remember. We tested older adults on a task in which participants viewed words paired with point values and “bet” on whether they could later recall each word. If they bet on (...)

    Relational Integration in Older Adults.Indre V. Viskontas, Keith J. Holyoak & Barbara J. Knowlton - 2005 - Thinking and Reasoning 11 (4):390 – 410.
    Reasoning requires making inferences based on information gleaned from a set of relations. The relational complexity of a problem increases with the number of relations that must be considered simultaneously to make a correct inference. Previous work (Viskontas, Morrison, Holyoak, Hummel, & Knowlton, 2004) has shown that older adults have difficulty integrating multiple relations during analogical reasoning, especially when required to inhibit irrelevant information. We report two experiments that examined the ability to integrate multiple relations in younger, middle-aged, and older (...)

    Retention Systems of the Brain: Evidence From Neuropsychological Patients.Barbara J. Knowlton & Indre V. Viskontas - 2003 - Behavioral and Brain Sciences 26 (6):743-744.
    Studies of neuropsychological patients are relevant to models of how long-term memories are stored. If amnesia is considered a binding deficit and not a difficulty in transferring information from short-term to long-term memory, it is unclear why context-free semantic learning is impaired. Also the model should account for the reverse temporal gradient seen in patients with semantic dementia.

    Relational Complexity, the Central Executive, and Prefrontal Cortex.James A. Waltz, Barbara J. Knowlton & Keith J. Holyoak - 1998 - Behavioral and Brain Sciences 21 (6):846-847.
    Halford et al.'s analysis of relational complexity provides a possible framework for characterizing the symbolic functions of the prefrontal cortex. Studies of prefrontal patients have revealed that their performance is selectively impaired on tasks that require integration of two binary relations (i.e., tasks that Halford et al.'s analysis would identify as three-dimensional). Analyses of relational complexity show promise of helping to understand the neural substrate of thinking.

    Recall, Recognition, and the Medial Temporal Lobes.Barbara J. Knowlton - 1999 - Behavioral and Brain Sciences 22 (3):455-456.
    Aggleton & Brown predict that recognition and episodic recall depend on different brain systems and can thus be dissociated from one another. However, intact recall with impaired recognition has not yet been demonstrated if the same type of information is used in both tests. Current evidence suggests that processes underlying familiarity-based recognition are redundant with processes underlying episodic memory.
