Compassion is the light that shines in the eyes of those who care
Towards a more Humane Society. Contemplating an emotion, 1 line a day.
Our divided and conflicted world needs compassion more than ever. #MentalHealth.

Egocentric spatiotemporal perception
Concepts in Sensorimotor Research.
It is a fundamental aspect of self-consciousness and scaffolds our subjective experience of being present, in the here and now, which is vital for our survival and wellbeing.
Alterations may lead to feelings of self-detachment, self-fragmentation, and body and world alienation.
Disability in Strength
A new mural titled “Disability is Strength, at Oakland Airport honors visionaries who helped
build the movement for disability rights and independence, and present a vision for a future of full inclusion, rights and justice.The mural features disability rights pioneers Ed Roberts, Judith Heumann and Brad Lomax.
Judy Heumann, one of the great and recently deceased disability rights early advocates once said, "Independent Living isn't doing everything by yourself – it's being in control of how things are done."
Compassion is the key that unlocks the door to forgiveness

Depersonalization and Autism
What is Depersonalization Disorder (DPD)
- Loss of body ownership /disembodiment feelings / somatosensory distortions/ loss of agency: distressing feelings of being 'spaced out', detached from one's self, body, and the world (observing yourself from a distance).
- atypical 'flat' time perception (alterations in perception, including disruptions in the perception of time. )
Research findings on DPD and atypical time perception in the NT population
- Distorted perception of time: Tendency to overestimate the duration of time intervals, perceiving time as slower than it actually is which can contribute to the overall sense of detachment (1,2)
- Neural correlates of time perception: fMRI studies show differences in brain activity and connectivity patterns in regions associated with time processing, eg: PFC and parietal cortex (3,4)
- Role of attentional processes: Difficulties in allocating attention appropriately, leading to a reduced ability to accurately perceive and process temporal information (5,6)
- Emotional factors: Emotional states, eg anxiety and stress, can modulate time perception, leading to temporal distortions. DP folks often experience heightened levels of anxiety and emotional distress, which may contribute to their altered perception of time. (1,2)
- Both involve atypical sensory processing suggesting a potential shared underlying connection.
- Overlap in Symptoms: Though there are distinct dx criteria, both share some overlapping symptoms, such as a sense of detachment from oneself, difficulties with emotional regulation, and social challenges.
- Neurobiological Factors: Though the specific mechanisms and neural circuits may differ, both potentially involve alterations in brain functioning and connectivity.
- Impact on Functioning: Co-occurrence may exacerbate the challenges in everyday functioning especially in areas of social interactions and emotional well-being.
Research Findings in Autism and Implications
- 17% autistics met the diagnostic criteria for DPD, compared to 2% non-autistic (7)
- Compared to controls, autism+DPD more likely to have
- higher anxiety and depression (8)
- more difficulty with social interaction and communication (9)
- more repetitive behaviors and special interests (10)
