  • Diminished preparatory physiological responses in people with dementia

    Open AccessK H Chen, Julian A Scheffer et al.ARTICLEThe Journals of Gerontology…2025References: 3

    Objectives Emotional impairments in people with dementia can be taxing for family caregivers. However, caregivers differ in their resilience to these challenges. We previously found that, compared to healthy controls and people with Alzheimer’s disease, people with frontotemporal lobar degeneration (FTLD) have smaller physiological responses when anticipating upcoming emotional stimuli. This impairment may leave these people with FTLD unprepared …

  • Is Broca's area critical for speech and language? Evidence from lesion-symptom mapping in chronic aphasia

    Open AccessTimothy J Herron, Krista Schendel et al.ARTICLEFrontiers in Language Sciences2024

    Introduction The specific role that Broca's area plays in speech and language has been hotly debated in the literature. Some research has pointed to a specific role in particular aspects of speech production, while other findings have suggested additional roles in aspects of language comprehension. In the current study, we had the opportunity to take a broad approach by analyzing lesion and behavioral data from a large cohort of left hemisphere s…

  • Responding to the emotions of others

    Open AccessSandy J Lwi, Claudia M Haase et al.ARTICLEEmotion2019

    Responding prosocially to the emotion of others may become increasingly important in late life, especially as partners and friends encounter a growing number of losses, challenges, and declines. Facial expressions are important avenues for communicating empathy and concern, and for signaling that help is forthcoming when needed. In a study of young, middle-aged, and older adults, we measured emotional responses (facial expressions, subjective exp…

  • Age-related changes in emotional behavior

    Open AccessAlice Verstaen, Claudia M Haase et al.ARTICLEEmotion2018

    We examined age-related changes in emotional behavior in a sample of middle-aged and older long-term married couples over a 13-year period. Data were collected at 3 waves, each occurring 5 to 6 years apart. For the present study, only couples who participated in all 3 waves were examined (n = 87). Couples were either in the middle-aged group (40-50 years old, married at least 15 years) or the older group (60-70 years old, married at least 35 year…

  • Positive urgency and emotional reactivity

    Sheri L Johnson, Claudia M Haase et al.ARTICLEEmotion2016

    Positive urgency, defined as a tendency to become impulsive during positive affective states, has gained support as a form of impulsivity that is particularly important for understanding psychopathology. Despite this, little is known about the emotional mechanisms and correlates of this form of impulsivity. We hypothesized that positive urgency would be related to greater emotional reactivity in response to a positive film clip. Seventy-five unde…

  • Short alleles, bigger smiles? The effect of 5-HTTLPR on positive emotional expressions

    Open AccessClaudia M Haase, Ursula Beermann et al.ARTICLEEmotion2015

    The present research examined the effect of the 5-HTTLPR polymorphism in the serotonin transporter gene on objectively coded positive emotional expressions (i.e., laughing and smiling behavior objectively coded using the Facial Action Coding System). Three studies with independent samples of participants were conducted. Study 1 examined young adults watching still cartoons. Study 2 examined young, middle-aged, and older adults watching a thematic…
